Colorado Prospector - Gem and mineral prospecting and mining forums _ Prospectors and Rockhounding Field Work _ COLORADO DIAMOND PROSPECTING

Posted by: ASTROBLEME Nov 21 2008, 07:26 PM

Hi Everyone:

Diamond prospecting isn't too hard if you know what to look for. This photo was recently posted publicly by another diamond expert (Dan Hausel) whom I've worked with and have grown to respect over the past few years. I am excited to now be able to share some knowledge through this forum as I have endured much difficulty in the early years while learning about diamond prospecting on my own.

The specimens in this photo are great examples of "indicator minerals" that were recovered from a diamond bearing area (Sloan Ranch kimberlite pipes #1 & #2) right here in Colorado. If you ever find minerals that resemble these specimens in any of your samples, I'd advise you to consider testing the prospect area for DIAMONDS!

Sincerely,

ASTROBLEME

Of course, the best indicator of a diamond mining deposit is to be successful in finding diamonds.

Here is a photo of my first diamond recovery a few years ago. It is hard to explain the excitement...even today...at finding diamond crystals right here in Colorado!

Here's another photo that you might enjoy. The building was a diamond processing plant that worked the kimberlite pipes on the old Sloan Ranch back in the 1980's. The flat areas up to the right of the building are the reclamation efforts that cover some of the kimberlite.

Chuck Fipke later used the plant to process the first cores taken from the ice covered lake that held his fantastic Canadian discoveries…since it was the only diamond processing facility in North America at the time.

Very cool diamond find Astrobleme! cool.gif I bet you were a happy prospector that day for sure!

I remember an excellent documentary done about Chuck's Canadian adventures, very good story.
And the ending description about what he did after his success and he sold the mine........he headed right back out to prospect for more. happy088.gif emoticon-misc-004.gif

Thanks for posting, great stuff! Like NM Jack said.....Keep it comin'!

Dear CP:

I got the urge to prospect for diamonds about two decades before finding that first stone, so I can relate to Chuck and his story. People dismissed his diamond pursuits and some even joked about him early on. He had a tremendous passion for diamond prospecting that gave him the will to continue on in the face of what most folks would consider unbeatable odds. Of course, many of us can really understand why he keeps prospecting...even when he has already had tremendous successes.

Sincerely,

Hello Everyone Prospecting for Diamonds:

Kimberlites that contain diamonds also carry several other minerals. The most well known are the garnets. Many diamond prospectors search for these garnets since they are much more numerous than diamonds. The colors can be very different and the best way to tell if a garnet was from a diamond bearing pipe is to do a detailed analysis on the chemistry.

Why? Because diamonds contain inclusions and some of those inclusions have been identified as being garnets. The garnets that have the chemistry known to be found in diamond bearing kimberlitic pipes are described as G-9 or G-10. I have collected garnets ranging from purple through wine to bright red in coloration from the surface expressions known as pans in the State Line Mining District. The color isn't so much as an indicator of a kimberlitic pipe containing diamonds as the diamonds are. It is my opinion that far too much time and money is being spent around the world looking for "diamond indicators" than there is actually digging up diamonds!

Here's a photo of some of the garnets I have collected from diamond bearing kimberlitic pipes here in Colorado.



As you can see, these don't look too impressive but the diamonds that come with them sure are...

Take another look at my first diamond photo. The red coloration of the matrix is the eclogite garnet mineral. The cubo-octahedral crystal developed within that diamond- eclogite xenolith matrix a long time before it was delivered to the surface. Diamond crystals come in many forms and not all of them appear to be diamonds when first collected. Some have suffered damage during deposition and others can take an uncommon crystal form so check your concentrates carefully. Most diamonds break away from the matrix and are found in a "clean" state without any trace of the matrix. This is due to the diamond being so much harder than the matrix. The diamond crystal is the only thing that survives the through the erosion process. If you ever find a diamond with the matrix attached, you are very, very close to the diamond source. Take your time to properly sample the area to determine where the diamonds are eroding from.

Hope this helps in your recognition of possible diamond deposits.

Sincerely,

ASTROBLEME

Heck, I would be happy just to find those indicator minerals you have posted at the top. The color of those garnets is awesome

Posted by: jim Dec 5 2008, 07:57 AM

Very cool stuff. That means that Mr Tonko has come close to his sorce since the stone in the first pic has matrix still stuck to it. It makes since too. Being that diamond is harder than ALL its surroundings it just gets polished. I'd love to hear his story.

nm jack:

While I travel through NM occasionally, I have never had the chance to do any prospecting. I'm sorry that I don't have any information on NM diamond deposits.

If you haven't already done it, let me suggest that you zoom in on you claims using the Google Earth tool. A good quality color photo of your claim coverage may help identify the central core of the blue ground where sampling would be the best. Here's a Google Earth image of a cluster of some of my pipes expressing both "yellow ground" and "blue ground" materials.



The circular pans (some call them mars or craters) are highly visible from aerial photos. The depressions seasonally fill with water making sampling difficult when the clay is muddy. LOTS of sampling is required to determine if the target pipe has diamonds.

This Is the one I was Interested in , there was never a claim over here ever , I liked the name "lady moon lake" it has destinct craters in the lake Floor. This lake is private but the ponds were all locatable , i was going to claim it just cause how it looked on google earth ,Couldnt locate ON so i lost interest these were even over 2 miles from diamonex as their sister company was going to work with me as long as i was 2 miles away from diamonex , I thought of the sites upon visiting poor Targets and lost interest , but the large lake remains a mystery ,

Id say with all the attention in this area someone should make an effort here , even though the lakes private look at it! It Looks Special , WHAT IF , could be , even part of sec 1 is locatable

But Thanks Anyways Dan and Denise whom helped answer many questions about claiming , but thats what happened to the lakes that i was talking about possibly filling on. as shown never seen a claim



 

 

Posted by: Bennie Dec 10 2008, 07:50 AM

to clarify my last post about lady moon ;
this is a private lake but could be leased and drilled maybe even mined , this is an unexplored pipe in the red feather lakes region

While telling dan i was going to explore this area i asked if he been there before and he said;

"even though the lake was private Lady Moon this was top of his list of places Given to diamonex to investigate "
personal communication Dan Hausel 2008

this is 1 of Dans Discoveries ...

some of the area is locatable but the lake itself is private but most of the surrounding is NF Land and is locatable almostl all the way up to the large lake which is private

I explored some of this area and didnt find anything keeping my attention and the larger better portion of the anomoly was private, so i left this area

I am not liable for any use or misuse of this place or idea ,this information is for a professional company that wants to drill, this area might be worth poking around ;)
this is a target that needs alot of groundwork but is a free reference and possibly a free diamond mine to be found haha
there may be another hidden intrusion on some of the claimable adjacent NF land or maybe a lease can be arranged on the private lake .

Posted by: ColoradoProspector Dec 12 2008, 11:24 AM

Nice arial of your kimberlite pipes Astrobleme, can sure see a distinct difference in the deposited material. Would definately enjoy finding something like that someday......very cool!
So when out prospecting and you notice a clear "difference" in ground color, rock form, etc......that would be a great place to check out!

Diamonds normally aren't found with any matrix if I remember it right so yep I would agree, musta' been right at the source. excited.gif

Great info Bennie thanks, sorry to hear you lost interest in that area though. Many times private land owners will make lease arrangements to work deposits within their land, just never know until you inquire with them.

Oh fiddlesticks! Now I got a hankerin' to go out diggin'! emoticon-misc-004.gif See what ya'll did!
Great info, and we would love to hear more about the prospecting stories and work that followed for those pipes Astrobleme......with lots more pics of course! biggrin.gif

Dear CP:

Here's a pic of my first pipe discovery. The "soft" kimberlite eroded during many, many milions of years, leaving a crater like basin inside steep walled "hard granite" cliffs. The steep walls now surround a lake that has formed over the clays resulting from the breakdown of the kimberlite. Other researchers have noted that grass prefers to grow over kimberlite pipes but trees avoid it. You can really see the tree line well above the waterline here.



I'll give a look through my files and see if I can find a couple more pics you'd enjoy.

Dear CP:

Here's a photo of the site where the first drill sampling of one of my discoveries was initiated. This lode claim target is named the "Sands of Time" and it is situate within the South Lost Lakes Placer Claim. It was drilled to a depth of 300 feet in the fall of 2007.

Dear CP:

This is a recent photo of the surveyed access route that leads into the USFS approved drill site at Lost Lake. As I'm sure you will remember, this is where I had the "CLAIM JUMPER" problem with Bennie Ulibarri.



Notice how the United States Forest Service places the drilling equipment access route below high water line. This is an effort to reduce vegetation damage as much as possible.

ASTROBLEME

Dear CP:

This pic is of Diamond Mountain. The rock mountain lies within the State Line Mining District. It was named way, way before anyone knew there were any naturally occuring diamond deposits nearby. I think that possibly this area had some involvement with an old story about a diamond hoax but the details escape me at this moment.

Posted by: ASTROBLEME Dec 12 2008, 06:22 PM

Dear CP:

I found another set of recent photos (Sept 2008) that detail what a kimberlite target drill site looks like. These two photos are of one of the lakes that are visible in the aerial photo I posted earlier.

This is the actual staked drilling site...

[attachment=3060:drillholell2.JPG]

The view below is from the drill site southward that shows the staked access route into the drill site following along the lake shore. Again you will notice that the USFS is trying to mitigate the impact on perennial vegetation by keeping the equipment access route below high water line. Off highway vehicles tear through this muddy area illegally and I have seen my blue ground splattered along roads 1/2 mile away from this site as they leave the area with my blue clay on their tires!

You can see again that the trees standoff from the kimberlite pipe but the grass prefers it. This is a great field indicator for possible sample sites.



ASTROBLEME

Posted by: ASTROBLEME Dec 12 2008, 06:36 PM

Dear CP:

Here's another photo I've taken recently. Bennie previously posted his "discovery" pics of my claims a few weeks ago on this forum at

http://www.coloradoprospector.com/forums/index.php?showtopic=2338



Thank you for closing that thread. I really get upset with people who vandalize claim stakes. In my photo you will see both the drill site stake and the USFS marker that were torn down and thrown into the grass. This happens far too frequently and that is why I warned everyone that the area was already under claim. I hope that something can be learned from all of that.

Dear amethystguy:

I think the grass anomaly follows pretty much around the world if the climate is right. Another thing I've seen on occasion in the State Line Mining District is animals digging into the grass anomalies. This might be due to them trying to get water or maybe the grass has better nutrients. This "dugout" had blue clay about 1 meter down.

Fantastic info and pics Astrobleme.......very cool.
Can't wait to hear about the successful drill tests too.... happy088.gif When it comes time to start excavating let me know, I'm pretty good with some of them big yellow dirt tools! laugh.gif

I bet the water has alot to do with where the grass/trees grows too. With the natural depression holding more moisture longer in that area would definately cause different vegetation and fawna. Notice the aspen trees all right inside the pines? I'm no tree surgeon laugh.gif but I think aspens tap roots need to reach water where as pines don't do well over the long term in that same moisture. Gives us a clue, as it did many old time prospectors, to where water is or isn't close to the surface.


Hope to hear more about these soon, thanks for sharing. Great stuff!!

Dear CP:

I'd love to tell everyone all about these claims that have been approved for drilling by the USFS but I'm somewhat limited in the level of detail I can provide. My family's company accepted "an offer that can't be refused" a couple of years ago. Once that happened, the proprietary nature of those claims involved should be respected, so I prefer to not reveal too many details publicly. On the otherhand, since I have had so much trouble with claim jumping and vandalism, I am now publishing this map of those claims in an effort to inform the public as to these important holdings.



I can say that I have recovered diamonds with a No. 2 shovel on some these claims before they were under contract. It is my hope that others can find the information they need to go out and discover their own diamond deposit with the information I do post here.

Many diamond developers look for good drill core results as they are looking for large kimberlite resources that they can develop into a mine producing a revenue stream for many years forward. That takes lots of up-front money and these arrangements may not benefit the recreational prospector. Sure, a prospector can sell out for some quick cash but he/she will never see the full value for their discovery.

It has been my experience that lots of money can be made by extracting diamonds that have already been "mined by mother nature". Given the nature of kimberlite being much softer than the hard granite surrounding it, the erosion process liberates the diamonds naturally. No need for an expensive roller crusher or other high tech devices if you can find the pan that holds the diamonds within the crater walls. If the pan has already eroded out, look down-stream for the stones as they do not wear out easily. In areas that have been subjected to glacial ice movement (Colorado has some!), then you need to look down-ice to see if there are any concentrated placers.

The pan, crater, or diatreme in my mind, is acting much like a natural gold pan. It holds back the heavy minerals like diamonds and garnets while the other rock breaks completely down and then washes or blows away. This process lasts millions and millions of years and the crater like depressions holding the diamonds may not be easily recognized at first. Many fortunes have been made quickly by working diamonds concentrated into placers...especially the pans that form over the pipes. Small companies working in Africa have done this for years but the knowledge isn't really shared.

There is some public information that I can share that is available and may be of help, so here's the link...

Hi amethystguy:

I'll try and answer you as best as I can.

My family's company holds numerous mining claims for uranium, lead, zinc, copper, silver, gold and gemstone deposits. The map I've put up is only for some of my claims. It only shows those claims that are presently under contract for diamond exploration by another company and have been the subject of claim jumping here in the Forum. There are other areas under claim in that area that aren't shown on the map. Those areas are public records and can be found by using BLM LR2000 or even hiring a mining consultant if need be. Remember that each individual claim has a Location Certificate and Claim Map on file in the County Clerk and Recorder's Office as well as the BLM State office. Those documents have the legal descriptions and the maps are on a 1 inch = 500 feet scale.

On the map I posted, the scale is in miles, so the detail isn't as good as in the public records. I just wanted to give folks an idea as to where the claim jumping has been the most severe and prompt them to use caution when prospecting in those areas. The pink lines indicate the boundary lines of my placer claims and the black lines indicate the boundaries of the lode claims. If you have a specific location in question, please feel free to contact me via e-mail at
johnny.tonko@meteoritecrater.com
for details.

There is no limit on the number of claims that a person can have. If someone has more than 10 claims nation-wide, they can no longer qualify for the small miner exemption. That means they must pay the annual assessment fees of $125 per claim plus additional county court filing fees as well.

My company pays many thousands of dollars each year in claim assessments. When you figure in all the additional costs for prospecting, surveying, lawyers, assays, geological consultants, accountants and taxes...there isn't much left to show as profit for all the work that goes into the venture. That is part of why it really upsets me when my claims get jumped, especially when I am willing to negotiate leases to interested parties for exploration on some claims. I really want to help folks learn about mining claims and will try my best to do that. However, there are a few people that abuse the records system to find where deposits are and then they make it a point to go there to collect minerals illegally. My hope is to prevent mineral trespass by education (this Forum is a great way to get out information) before the problem arises.

Hope this helps explain the map.

Sincerely,

ASTROBLEME

sometimes people make mistakes even county clerks ,as they givin me the wrong page's on these claims ,

also due to the camping and fishing symbols on all of my road map's, I made the assumption that the bottom lake was unclaimable just like the bottom Creedmore Lakes were

Its not a "recreation area" even though there is many campsites on both sides of the lake and the maps say "picnick area" even your map does , my atlas had fishing symbols on this lake lol

Im sorry Astrobleme , I didnt know it was claimed and even claimable for that matter , im sorry , i would of never been there had i been furnished the correct information

it will not happen again , im a busy bee and i will be buzzing new areas

im sorry for reacting the way I did there tonko ,

Hausel said your a nice guy , this was a misunderstanding to boot , i was wrong

also i would like to see a clearer picture of that diamond, in the picture it resembled a tan chlorite, the picture is aweful dark though

Trees dont like to grow into these pipes , I believe it to be a response from the tree , not wanting to set roots in the magnetic and conductive soils , I have seen baby trees growing in pipes but I Imagine the blue clays blended with the country grus to make a tolerable soil when these were setting roots(see attatched photo). Worldwide there is trees that do grow in pipes and its reported that some of these orchards are much lusher and green that the surrounding Trees , Probibly due to the high micro-nutrient content of these eroding blue clays. I dont believe the trees Cant Grow in kimberlite , I Believe it to be true that the trees just dont want to, but when tricked into growing in it , they grow great (notice the large tree bigger than all the others and the 2 baby trees all growing in a wheathered pipe)

I believe it to be forseeable that trees can grow in pipes , under rare unknown circumstances trees can be tricked into setting roots.
but Trees in general dont want to grow in it and they generally dont. but they could grow in it (see attached image) , I believe if theyre tricked into planting roots , theyll like it , and grow in it

Cool Stuff , hope this answered your question Jason ...

These pipes can be found under mountains under valleys and even under lakes ,

I estimate that Lake anomolies in general make up less than 8% of known kimberlites world wide.
as far as lakes , there has been a number of these lakes anomolies discovered in canada in recent years ,Some of these lakes are now world class Diamond Mines , and these lakes had very rich kimberlite but is burried under 50- 100 meters of unmine-able kimberlite, some examples of these lakes that are recieving a bunch of attention in canada are ; SnapLake ,KirklandLakes ,PellattLakes ,Wekusko Lakes ,Contwoyto Lakes ,small lake ,Smile Lake ,Mud Lake ,Whitefish Lake , and others , based of some of the field reports reguarding these Canadian lakes , I have a neutral opinion on the colorado lake anomolies, some cases were destinctly simmilar to Canada some werent.
These Colorado anomolies 10 miles South Of The State-Line District Could Be Great Sites , the likleyhood a collector would find anything is near impossible, and most if not all of these Lakes are claimed and off limits in that capacity , Diamonds when mined are found by bulk loads by the metric tons or tonnes and ore grades are calculated by the 100 metric tons or 100 tonnes , ore grades for commerrcial mining vary anywhere 35.CPHT's-300+CPHT's (carats per hundred tonnes) . Hausel wrote "even the richest deposits , diamond is less than 1 part per million"

as a personal request to anyone reading , please dont vandalize claims , or act on anything im posting , this is soley for educational purposes to those who want to learn a little about kimberlites and how to identify them ,

Im writing a great How To Book ; on how to find and identify kimberlites and even help you prove out an kimberlite or unconventional host rock in the field !!! .
should make for some interesting reading to say the least , when completed I hope to get her published iin the future

Do you guys have a specific book or reference material to check out regarding finding, identifying, and mining diamond deposits? I thought about getting Elrich & Hausel's book. I already have 2 or 3 books about diamonds but I want something more specific, more atuned to what I said. Any suggestiuons?

the world of diamond deposits is a very secerative world , there is little spoken of the techniques and ways they find deposits and even less information on mining Feasability and Evaluation techniques reguarding Kimberlite , Most of which can and are done out in the field .

heres some of the Best Books ive found on the subject >>>>(see attached photos)<<<<

Hausel has a new book to be Released 2009 and will be readily available on amazon.com (see attached photos) that ones suppose to have a bunch of diamond info and other gem occurances , should be a good one
theres also a title I need to get called "Barren Lands" I hear its a Good Find too

Hello Everyone:

Hope you had a Merry Christmas!

The State Line Mining District where I have the diamond claims staked is related to an impact crater-like formation called the Virginia Dale Ring Dike Structure. The remnant ring dike rims that are still visible create a crater like expression at least 12 miles across. This structure has similar characteristics to the larger Vredefort Ring in South Africa. Several diamond mines had been developed around the Vredefort Ring long before it was confirmed as an impact crater. As yet, I have been unable to find firm evidence of impact at Virginia Dale but interestingly, the old Kelsey Lake diamond mine sits squarely in one of the rings!

It was amazing to me to see the kimberlite pipes emplaced into the deep granite crust west of Fort Collins and I was curious as to why it occurred there and not everywhere else that there was an ancient thick granite crust. I've developed a theory that diamonds were being brought up by the ancient impacts of large meteorites/comets and I have mapped many diamond areas around the globe that were located within or near impact craters. My thinking is that the over-pressure put upon the crust during an asteroid or comet impact has allowed for kimberlite magma to be ejected through the crater ring "cracks" generated as a result from a reflex shock wave generated during the hyper-velocity impact. I would say it is kind of like putting your finger tightly to an orange peel and watching the juice "erupt" from the skin. Kimberlite emplacement is always from deep sources and it is fast and quick...not prolonged like normal volcanism. As it turns out, the Russians had also observed this phenomenon and have made diamond discoveries near craters within the past few decades. The Virginia Dale Precambrian Ring-Dike Complex was first recognized by W. A. Braddock in 1962. In 1968, D. H. Eggler researched the structure and wrote his thesis on his findings. In 1970, R. S. Wing and L. F. Dellwig thought the structure may have had an influence on the Ferris-Aultman and other known Paleozoic age diatremes in the State Line vicinity.

Many scientists had dismissed the potential for meteorite/comet creation of the Vredefort Ring. The same thing has happened with Virginia Dale, in my opinion. Please consider my advice here...if you are prospecting an area near a known impact crater, I'd suggest that you also look for diamonds that may be associated with the crater. If the initial impact didn't bring diamonds to the surface, the resulting fractures in the granite may have allowed for later intrusive events to find a way up to the surface. In fact, many kimberlite pipes have shown multiple emplacements within the same diatreme. This makes sampling even more important since some parts of the pipe are too lean yet other intrusions have plenty of diamonds. Here's a USGS photo that I touched up with the ring dikes as related to the Kelsey Lake diamond mine.



I recently recommended a book to a poster that isn’t so much a prospecting guide but rather it is a scientific monograph devoted to diamond bearing rocks. The book is titled Kimberlites, Orangeites, and Related Rocks by Roger Howard Mitchell of Lakehead University in Thunder Bay, Ontario Canada. It was published by Plenum Press and I think it is a great resource. The book summarizes much of what has been held “secret” for so long and it is a must have for anyone serious about finding diamonds. My copy ran about $200 US a few years ago so if you can find a good condition used copy, that may be the way to go. I hope that the information I've provided here is of some value to you.

Sincerely,

Can you look for shocked quartz to determine if there was an impact? Well, I guess it would have been so long ago that most of the sign would have eroded away. good read Mr. tonko

So much erosion has occured in the publicly accessible locations that I haven't been able to collect any shocked quartz specimens. Perhaps there are some remaining on the private lands but I don't have access into those areas.

thats some interesting concepts there JT ,

In the Kelsey Lake Area, "there are atleast 5 major Faults which help controll the location of the pipes" (Eggler and others) .
many other pipes throughout the district are ON or near major faults,
An excellent Documented Example Are the sloan 1&2 Kimberlites in colorado, where these pipes are situated ON the "copper king fault" and ON the "prairie divide fault "

throughout the district a good portion of all Anomolys are Fault controlled pipes , when looking for kimberlites, "im looking for kimberlite" lol , im looking for where it escaped. and where it came out the ground and can be found , im looking for all or any clues to help find them , I tend to stay looking around favorable precambrian basemented areas , Faults In Precambrian Basements are favorable terraines to host kimberlites , and are good places to look...
theres Millions's of faults to be investigated in these precambrian areas ,,,


Also some areas of these precambrian outcrops are host to hot springs and gold and platinum group mineralization and other anomolys and or subductions, which make portions unfavorable to host a kimberlite , like southern colorado the (AKA the gold rush ,Southern Colorado!!!),
But its all about the Kimberlite Intrusive , where did it pop out at , then Diamond Feasability and the possibility commercial mining is definatley another can of worms so to speak

most people wouldnt be able to identify a kimberlite , even Chronic and Ferris in 1960 when they discovered Both the ferris and aultman kimberlites in wyoming (which are private and owned) they didnt know it was a kimberlite ,they did notice lower paleozoic carbonates surrounded by precambrian the granite , discovered by chronic and Ferris in 1960 and identified as a kimberlite by McCallum in 1964
these anomolys apear to be partially fault controlled aswell as many kimberlites worldwide .

I found an interesting youtube video along with this picture which will kind of explain favorable terraines for diamonds this video is GREAT 1!!! http://www.youtube.com/watch?v=QDqskltCixA now find the stablest and Oldest portions of the craton and look for an destinctly different intrusion there LOL

colorado can have kimberlites simmiliar to Africa and Australia and geochemmically tested some do ...

thanks for letting me contribute , if you wanna read anything else I authored youll have to wait til I complete my project - But I will let you all know

Thanks for reading and watching

Did any of you guys ever sluice "down stream" or in the drainage basin of these kimberlite areas? Didn't I read somewhere that 1000's of feet of overlay in that area had eroded away which would include the kimberlite pipes. That would make for areas of high concentrations of loose diamonds in gravels and stream beds. Another question why is there an absence of "yellow ground"? Is the kimberlite not decayed enough? thanks

Sure seems like a good idea Jason! happy088.gif

The impact theroy has me just fascinated! Thanks for the input Johnny. I can see how many folks in the public would have a real hard time with the whole scale of the theroy......an impact so severe that life on the planet probably changed dramatically and may well have caused the earths crust to crack (shock waves) possibly setting off dormant or un-erupted volcanos for hundreds of miles around the impact and then of course causing magmatic eruptions through the created faults. WHAT A SHOW THAT MUST HAVE BEEN!
atomic.gif
Then try to imagine on top of all this that when the impact occured, Colorado was, more than likely, completely underwater as well as not having the Rocky mountains evolution at that time, or at least not as they stand today or even close. WHEW!
I find the theroy not only fascinating but very fesable and I bet in a short time there will be some histroy re-written from the new impact studies recently undertaken by several researchers. TOO COOL! cool.gif

as far as diamond bearing kimberlites in the stateline district go ,
lets go off facts ok

fact is all these kimberlites are found in an Archean portion of the Craton , Like everywhere else in the world that diamondifferious kimberlites are found . and these are a intrusions in this solid basement.

a volcanoe would burn a diamond up , a kimberlite freezez and isnt Molten hot , the second a diamond was Forged its frozen and preserved and within seconds kimberlite is transported to the surphase a frozen mass that thaws and then erodes , full of mantle rocks and misc specimens preserved in the kimberlite its undeniable the heat it takes to make a diamond but its undesputable at that temperature that shortly after the crystal is created it can be graphitized (burnt) .

as i posted before , when kimberlite erodes it releases acids and it disolves everything in it except diamond leaving a clay with other colored clays in it

WATCH THAT VIDEO 2 POSTS UP , you can see the kimberlites bieng made, CARBON DATING PROVES these pipes in colorado and wyoming to be between 200 and 800 million years old in age Coincidentally created at the same time these cratons were bouncing around which did infact happen, this is the best example i can give you as far as the creation and formation of diamond and kimberlites =Watch the videohttp://www.youtube.com/watch?v=QDqskltCixA

Dear Bennie:

I am totally in agreement on the kimberlite "freeze" process. The currently accepted theory is that the large content of carbon dioxide gas trapped within the kimberlite starts acting as a cooling agent when the pressure is released. Some of the diatreme walls I've seen at State Line don't show an alteration from heat like is found in volcanic activity.

My thinking is that once the pipe gets shot up from an impact over-pressure event on the crust, the fast moving kimberlite magma looses pressure as it breaks the surface and the carbon dioxide turns to gas. This pressure drop "freezes" the pipe. Super fast emplacement and if conditions were right, diamonds can be carried up and preserved in the process.

Impacts have been responsible for some kimberlite emplacement around the globe, but not all. At State Line, I am just saying that it sure looks to me like an ancient impact kicked off the process. There have been at least two major intrusive events in some selected pipes. Perhaps the initial ring-dike creation was from impact and the other intrusions were from subduction melting or other gaseous events.

absolutley JT

diamond preservation in kimberlites isnt a big issue, as the MgO contents in picoilemenites almost always proves that "kimberlites" tend to preserve diamond,when indicatorminerals , Kimberlites are common worldwide and Kimberlites make ideal diamond mines.
these gas and xenolith rich peridotic breccias freeze and dont weather and decompose until introduced to water when unwheathered theyre full of many rare mantle treasures some of which are extremely valuable gemstones other than diamond (eclogites,lherzolites, moissanite),

also graphite mines and nearby areas are totally unrelated to kimberlite . diamonds recovered from such operations are always graphatized and of poor quality even as industrial use

Dear amethystguy:

Thanks for the kind words. I'm glad you find the information useful.

This recent discovery of nano diamonds resulting from high speed impact has gotten me thinking...again. Knowing that diamond crystals will grow larger in the right environment, lab diamonds being grown on seed crystals are a good example, I think it may be possible that impacts may have created the "seed diamonds" that are now being mined as kimberlite eruptions. As the continental plates subduct, the nano diamonds and other carbon gets dragged downward into mantle where it is melted. It seems plausible to me that on a long time scale, these nano diamonds could develop into larger crystals. When the diamond bearing rock gets ejected up through the craton, the diamonds are transported from their deep growth zones in the kimberlite slurry.

At least that is something to consider, I think.

Sincerely,

ASTROBLEME

Dear Coalbunny:

Ask and you shall receive... spock.gif

Years ago, I acquired some raw field samples from what is now known as Crater of Diamonds State Park in Arkansas for my collection. The diamond deposit is actually an eroded lamproite pipe. I have been working on similar intrusive events here in Colorado. If you come across rocks (even in coal mines) that resemble those I've attached in this photo, they may contain diamonds and my advice is that a sample should be taken and properly analyzed.

Take care,

Johnny

I just moved to Laporte and hope to drive up there this spring a bunch to do some prospecting for diamonds and other rare mantle minerals. If anyone wants a 25 year old geology major as partner/apprentice in the area hit me up.

Also would sluicing with a gold sluice be best or a greese table/pan for finding my first diamond? I know a few people who dredge here in CO who say they have found a few diamonds in their cons.


Tom

Posted by: ASTROBLEME Jan 24 2010, 05:17 PM

Hello Tom:

It has been my experience that a pan or sluice will work fine without adding "grease". While a grease table works well in a controlled environment, the stuff that gets into the sluice out in the field really sticks to the grease if it has carbon in it. Bugs, roots, leaves and various other carbon based items will cause you more trouble than it is worth, in my opinion.

As long as your sluice is set up to catch the black sands, diamonds will also be trapped. Just keep the riffles clean and you should do fine. Be sure to get permission from claim owners and/or private holdings to avoid any problems. Diamond prospects are well patrolled up there.

Good luck!

Posted by: Forestwalker Jan 25 2010, 02:05 PM

Thanks for the advice, I was thinking that would be the case with the non polar detritus. I know how to set up the sluice to catch garnets which are a similar SG and I will clean up often.

Seems like its a railroad style checkerboard pattern of public and private land, how can I find who owns the private land?

I started prospecting in NH for gold and aqua/tourmaline and there are no claims so I am not used to the paperwork and claims research side but I know I have to be diligent to do right.

Tom:

You are right in the railroads establishing the ownership pattern. The checkerboard pattern has over the years resulted in numerous split mineral estates. In many locations, the government lands have private mineral holdings and the public lands have private mineral holdings. It takes some time to sort ownership issues out but if you focus on a small target area, that will help limit the complexity.

Larimer County has an awesome http://maps1.larimer.org/apps/lcparlocator/default.aspx?theme=maps/TaxParcel Use this resource to identify property ownership, overlay aerial imagery, USGS quads and more.

The Larimer County Clerk and Recorder in Fort Collins will also have copies of all the mining claims and claim maps.

Here's a link to Permit No. P2008001 that DiamonEx filed in an effort to revise their drilling plans for my claims at Bull Garden. The original plan was to drill multiple holes along a boundary fence to determine if the pipe continued onto adjacent lands. This revised NOI came just weeks before the company ran into financial troubles and was forced to cancel the project.

For those that find themselves in a position to move forward on a large scale project, remember that plans can be revised but it can delay permitting. Make sure to plan appropriately so that revisions are not required that will slow down a project or delay it unexpectedly.

Very interesting stuff on this link.
First let me say Hi to everyone as I am new to the forum but I am very old to diamond mining.

In my experience diamonds behave much differently than gold when it is washed away from the source material (Alluvial diamonds)

The old prospectors would and did find the odd diamond here and there but a sluice is not the right way to find diamonds. You need a diamond washing plant, they can be small or big depending on your budget.
The most efficient diamond plant is the 14 foot washing plant. Many of them are build to be a mobile unit that can be towed behind a truck or a serious 4 x 4.

The 14 foot pan is capable of washing many tons of gravel per day and you can sort the heavy concentrates almost every 15 minutes. You will need a excavator to pile the alluvial gravel onto a stock pile and a front end loader to pick the gravel up and feed it directly into the wash pan. No need to feed slowly since the pan feeds itself with buckets on a conveyor belt, almost like the old water wheels were powered. Similar concept.

Anyway if you can afford to setup this kind of operation you will need to make sure your tests are done in controlled circumstances I suggest you test the pan properly before you go into production.
The speed with witch the pan sorting arms turn must be very specific the consistency of the water and soil sludge must be %100 correct in order to push the diamonds out to the edge of the pan. If it turns too fast or too slow you will loose diamonds. So experience is the key, you must know how to tap the concentrates into a bucket (Old fashioned Milking bucket) and when to tap the concentrates out of the pan.

Once all this is done and you have your four to six buckets full of concentrate you have to classify and sort. Here we use a half a 44 gallon drum, and four diamond sieves about 20 inches across from large to small. Pour one bucket at a time into the top sieves make sure they are properly stacked on top of each other and the drum is filled almost to the top with water. Then you classify the stones the same way as you would gold bearing gravel. With diamonds it is slightly different because they are bigger than gold flakes. So you carefully scan the rocks for any diamonds. They can be any color so I always hold the top two sieves under a Blue light (Ultraviolet) All diamonds are florescent and they show up blue in color blue so they are very easy to spot.

The third sieve is usually where the diamonds are, up to three carats in size will be in this pan. This one you shake under water and rotate the pan about 15 degrees every time you shake it, usually about ten times this will rotate the light gravel to the outside of the sieve and the heavy stones will be in the center of the sieve if you do it right the black sand/stones will form a circle in the middle of the sieve.

Now you have to turn the sieve over onto the sorting table (In the shade) with one swift move, then drop the sieve a few times onto the sort table to make sure everything is out. Then comes the FUN part. I use a small 4 inch builders plaster trowel to separate and screen the concentrates. But usually the diamonds are lying on the top of the concentrates and they are easy to spot if you know what to look for.... just look for the bright one of a kind shine! I always run the ultra violet light over the rest of the wastes just in case, no one is perfect!
Well I hope this helps you a little in your prospecting endeavors.

No need to panic!

There may be confusion with the energy source being used to “light up” the diamond crystal. All diamonds will respond to x-ray but only one in seven (my experience...not scientific) will fluoresce under black light.

A Sortex x-ray machine was used briefly at the Kelsey Lake Diamond Mine (at the border of Colorado and Wyoming) just before it was forced to close after the landowner (Union Pacific Railroad) filed suit for mineral trespassing in federal court in the late 90’s. Many stones were recovered from the old tailings in early testing of this machine. It is my understanding that the Sortex machine was sold to a diamond interest in South America and was not used to a great extent in mining production due to the lawsuit.

If one uses a black light in the field for prospecting, it may be possible to identify some diamonds but many, many stones will be left behind. In the Stateline Mining District, one would want to use additional caution as black lights at night will attract numerous mosquitoes. There have been problems with West Nile virus in mosquitoes across Larimer County, Colorado. I would suggest using strong mosquito repellent, even if you aren’t using black lights after dark.

Diamond Digger posted this in the Off Topic forum under "Halo All Prospectors" topic. I found it very interesting since one of my first sampling efforts recovered a stone much like he was describing...

Hi,
Your questions are interesting. But you should never worry too much about how it got to the surface just that it is there!
I am not a Geologist but I held many pieces of Kimberlite in my hands and I sure know what to look for and how to spot it.
Garnets is the first indicator you want to see small dark purple ones. Then Feldspar, ilminite etc they are good indicators but a tip I can give you is to look for the pointer stone.... (Spits in the corner ) It is a dirty white stone small usually around 5-10 mil big looks like two separate stones joined by a dirty brown band... in any direction, hence dirty stone. The lore is you will always find a diamond right next to one of them. At first I thought it a joke so the old man took me into the field with a test sieve and we spend the day looking for dead gravel. This is gravel that does not bear diamonds. We did find some and it looked OK from afar but close up the indicators were gone. On the way back we did a quick hand wash of some promising samples and found a small .3ct diamond next to you guessed it.... a dirty stone!
Have fun.
DD



Here is a photo of the brown and white banded stone I recovered on my very first sampling effort for diamonds several years ago. After reading DD's post, I remembered the odd brown and white rock so I went back into my old samples and put together this picture to share...



The stone under the tweezers is the sharp edged fragment that was contained in the lake sediments that formed inside the granite walls surrounding my first kimberlite pipe discovery at the Stateline Mining District. I imagine that a similar sample that had eroded out of a pipe, after tumbling in a stream for some distance, it would look like the white and brown banded stone DD talks about. If you come across a sample like this in the Stateline Mining District, it is a "very good indicator" in my opinion.

DD, do you have any photos of the pointer stones?

Johnny,
Well yeah it looks like the same rock but once washed a little down a stream its a dirty old bugger and no idea why, you find one of them the diamond will be next to it.

Unfortunately I have no video or pictures of mining. Just never thought I will want any, how sad is that?

I am designing a new diamond wash plant at the moment.
So far it looks quite exciting so we shall see how it works once I get it going. I have incorporated a gold separation unit so if any gold comes into the plant it ain't going out thats for sure.
Have a good one.

There is just so much potential to mine diamonds.... sigh.... One riverbed produced a 7ct white stone that alone will pay for all my expenses building the plant! Massive untapped resources.
It is so frustrating. bash.gif

LOL so you have Eco-hippies as well; they are everywhere!
But mining alluvial diamonds is the cure for a bad personal economy. It is the only business I have ever been in where the turn of a sieve can hold $100 000 in sparklers.... no other business has that kind of profit potential.
Only one thing, I will bring all my knowledge build the plant set it up build a few more to sell on and get the money back (lol) train them lads to use it but this time I want a small share in the company.
Not making another fella rich and get nothing myself!
Anyway diamond mining is very Eco-hippy positive.. no mercury no chemicals of any sort nada nothing to pollute the environment. So they will have a tough time finding fault... but give them credit they try!

The law protects both the miner and the resource. If an individual miner or a mining company cannot comply with the law, they cannot do business. Pretty simple concept in my opinion. research.gif

I grew up in coal camps where a company would post a small bond, tear up everything that stood in the way of getting out the coal by strip mining and then...surprise after they cashed the checks for the production...go out of business and let the bond cover the mess. Well, the bonding was set so low that reclamation couldn't be funded so the taxpayer footed the bill. I saw the same trucks with the same drivers change their names from "Mining Company" to "Reclamation Company" and further profit from their earlier efforts! kick_can.gif

If the individual or company cannot comply with modern mining laws, they will not get the permits needed to operate. The government saw the same thing I did growing up...too many people jumping their bonds and walking away to let everyone else pay for their destruction.

Good mining plans will get approved with an adequate bonding fund to assure proper reclamation. info_grin.gif

Astro,
That mine can be made to pay but sadly it seems that it's not. Simple mistakes will cost you a fortune that's why you should never start a mine if you have to employ the so- called experts. If you yourself do not know what you are doing do not even try it. It will cost you...
I bet way to much was spend on setting up the "equipment" and salaries for the big boys.. what with a loan of $10Mil us? WOW
I can start a mine with $2 mil and make a success of it. Why? Not because I am better than the experts but because I grew up on a Diamond Diggings and I know how to get them out of the ground, (and I have done it before with much less cash), Hard Kimberlite or Alluvial gravel, the cheapest way possible. Being Cheap is what it is all about. You cannot spend money on anything that is not recovery related... I am sitting on Two Kimberlite pipes and I know I can make them pay within a very short time but I do not have the cash backing these guys had.
Phew! How could they loose that kind of money????
Makes one wonder.
Either way wish I was there lol

Hi Andy. Used to dig myself between Riverton pleasure resort and Windserton on place called Tipperary. Worked for DeBeers Geology back in the 70's I am at present in North Dakota working on the oilfields but is busy building a small prospecting plant and will take it to stateline area in Wyoming to hunt some diamonds there. Believe me there is plenty. Realy surprised that everybody is so focussed on hunting gold and overlook the better stuff."DIAMONDS" Man nothing like flipping that screen and there lies a 10ct shiny as hell.

Colorado and Wyoming have been in an extended drought for about a decade now. I have established water rights for the lakes that form over my diamond pipes. That water is used for processing the decomposed blue kimberlite clays that hold tight to the diamonds. This assures me an adequate supply for mining purposes without being curtailed by junior water rights holders or governmental entities that do not support mining activities.

In order for someone to start a wash plant this spring, there must be water rights or an augmentation plan that has already been approved in place for the 2013 season. If not, it will be very difficult to secure a suitable water supply to mine or run bulk samples given the current conditions and long term outlook. There has been a water component to mining activities in the west from the very start in the 1800's. Those mines that had the water rights were often the only ones that prospered. It is still the same thing today but the focus now is on high volume gold leaching, hydraulic fracking for natural gas and oil shale development. Water engineers and water attorneys are paid very well due to the demand for their services/expertise. Mining has always had many challenges and water in the west is still a BIG ONE!

Take a look at the newest Google Earth map photo overlays from fall of 2012 and you can see how much the natural lake levels across the Stateline Mining District pipes has dropped. If you use the "timeline" tool, you can see that the lakes are getting much smaller over time. This lack of precipitation is good for prospecting "new" targets but it will hamper wash plant activities unless the weather trend changes drastically in the next few weeks. I used this low water cycle to my advantage in the drought cycle starting in 2002. I was able to sample targets that I had identified but could not work previously due to the water being too deep over the lake bottoms in the many years before the drought. Now I am looking at a very different problem. If the drought goes on for another decade, I may have to seek out an x-ray machine or other device that is able to recover diamonds with much less water. Anyone ever heard of a "diamond dry washer"?

Hello everyone. I know this thread is a bit old but was hoping to find some info on if there's any good place to go to learn how to identify kimberlites, indicator minerals, etc. I'm just starting out with this hobby. I've been a novice rockhounder (forever it seems) and am definitely more in this for the hunt/discovery than thinking I'm going to get rich, but of course that would be a great side benefit. I'm hoping for some hands on experience but it seems I've jumped on this bandwagon on the tail end of local popularity as it seems the local gem/mineral clubs aren't very active. I'm ready to learn a bit more and start some serious digging as compared to the digging through dump sites, etc. as I've done in the past. Any direction would be much appreciated. I'm absorbing all I can from the web and Dan's info and am going to be looking into the many links/books that have been suggested here. Any other "must do's" for a beginner or location to go get some honest to goodness hands on "this is what you do" instructions?

Thank you!!

Misty-

Sounds like you've already done a fair bit of reading, which is good. Identification of kimberlites in the field, when you have limited to no experience with them, can be very difficult - even for seasoned geologists. The rock type just isn't that common, and there are many variations in the lithologies readily discernable at the outcrop level. Like all rocks/minerals, the ability to identify then accurately is directly associated with how much you have previously handled that rock type, and how well you undertand the processes that formed it.

I would suggest that you continue reading what you can - sounds like you've been reading alot of what D.H. has on the web in regards to the Stateline District? Then do a little research into the field locations. For looking at samples of kimberlite rock type, you'll need to visit the pipes themselves. Up in the Stateline District you should note that most of the accessible pipes on public land are under claim. There are a few that are not, but I know from personal experience that those not under claim are difficult to access. Outside of the Stateline District there are a number of well known kimberlites (and lamproites) in both Colorado and Wyoming that you can visit - Green Mountain, Iron Mountain District, Leucite Hills, Cedar Mountain, etc.. - just check on the land status before expecting to take home a bag of samples.

Due to the friability, and fast weathering rates of most kimberlites, there is usually limited surface expressions from which to sample rock mass. In some instances the rocks at the surface are not kimberlite in the truest sense, but rather rock fragments from other units penetrating by the eruptive event. Some pipes in the Stateline Distict have sandstone or carbonate float shows at the surface. All that said above, one can still collect kimberlite samples in the area without tresspassing or claim jumping - you'll just have to work for it. In fact I have a nice piece on the window sill in my office - massive kimberlite porphyry with a nice ~4mm pyrope garnet - collected from the Stateline District in the last year.

If it is kimberlite indicator minerals (KIM) that you want (pyrope garnet, chromian diopside, magnesian ilmenites, etc), the best way is to pan fluvial sediments near known (and preferably the larger) kimberlite pipes. Again, check out land/claim status, as there are a number of placer diamond claims in the Stateline, but I believe there is plenty of open ground that would likely be productive for KIM. Additionally, one can have success by sampling and washing soils directly from the kimberlite outcrop.

Hopefully that is somewhat helpful. Feel free to drop me a note if you have specific questions.

Posted by: russau Jul 31 2014, 03:59 PM

years back before my Geology Proff retired, he gave me a sample piece of" Missouri Kimberlite". But he said, it wasn't Diamond being material. this type of Kimberlit had small brown holes/tunnels in it like worm holes.

Hello, I appreciate all the educational info on the CP site. Could anyone fill in the gap between finding the diamonds and putting the money in the bank? I really need an expert in the business to guide me through the process and who to do business with. I'm planning a prospecting trip in August and hope to have all the methods and contacts worked out ahead of time so maybe, just maybe, the vacation will pay for itself. For example, who does one sell industrial diamonds to and how quick is the process? How would one do the same with gem quality stones and how is their value determined? I would love to start a career in placer diamond mining, just two old ladies with hand tools. Rocket

Posted by: MikeS Dec 11 2014, 09:30 PM

Hello Rocket! smileywaving.gif Welcome to the forums!
I have not mined any diamonds myself, however I recommend learning how to find legal ground to prospect first. There is much private property in and around the diamond fields here in Colorado. There is also active mine claims on the public lands. A good place to start is this topic:http://www.coloradoprospector.com/forums/index.php?showtopic=2638

There is lots of great information on this site to dig into to help you prepare for your first trip. I would suggest concentrating first on how to find some diamonds without getting yourself into a pickle.

Posted by: Somethin' Else Dec 26 2014, 10:19 AM

Hi, y'all! I'm Rocket's partner. We have had a great time researching land records (I do this as part of my 8-5 job). We've been doing it on the State Line District for about 6 months now. Both Astrobleme and Dan Hausel (in his two bulletins, 11 & 12) have been very encouraging, suggesting we don't have to drill kimberlites to find lots of diamonds, just "pick them up off the ground"' or dig in a streambed ("there's lots of diamonds in ******* creek"). (I've seen that photo of the double handful of diamonds. Is this for real?) Logically, in creeks below kimberlite lakes and on public land seem the biggest potential for gemstone finds. We were both wondering, however, how deep you have to dig in a typical mountain stream at 7,000 - 8,000 feet to get to those choice minerals? Are we talking 3 feet or 30 feet? It also appears on the land records that there are a lot of closed claims scattered about. Does this mean they were mined out? Or did those enthusiasts from the 2008-2009 diamond rush just get burned out and discouraged? We're still planning that August (or maybe July) vacation, and are wondering what affect the 2013 floods had on the mountain streams and roadbeds? Are many still closed? It's been great reading all the posts and getting a growing education on the life of a Colorado prospector.

Even the large operations in the kimberlite pipes have to process tons of material to find enough diamonds to be profitable. I would say it is possible to find some on the ground and in the right streams, however you may have to move lots of material to find one.

It always depends on the certain geological spot where the gemstones have concentrated. When digging in streams for float material, bedrock can be 1' down or over 30 ft. down. I have never dug a hole deeper than 4.5 feet below water line cause that's as deep as my chest waiters can go(digging for gold).

It can be that the material was depleted or it can be that it was unprofitable for the current conditions. I know many gold mines in Colorado didn't close because they were mined out, they just cost more to extract than they can cover in value.

Thanks Mike! You've been most helpful.

Someone has watched too much Gold Rush on Discovery.

Being a landman in O&G country (which is what I surmise you do based on previous comments) will be extremely more lucrative than any small scale diamond operations in the Stateline District.

Also, go back and do some more homework, as potentially productive ground in the district is much more tied up than you have implied with your comments. Note that there are alot of private roads that end in or pass through public lands for which you will have to negotiate access, and from what I hear, not everyone is so accommodating up there these days.

Your welcome! I have been searching for profitable gold for a few years now. I have not found that spot...... yet. I have found other minerals that may prove profitable. I rock hounded for fun for about a decade before going for profits. Some folk's are still finding profitable gold and other minerals in Colorado and making a living at it. Whenever I take a first trip to an area I expect to not find much to show but I usually find something to learn from. Most likely you will find some garnets or other minerals which can lead you to possible diamonds in the gravel. If you choose the right spot to try there is a good chance of finding a few low grade diamonds. Finding a quality diamond that can pay for your trip is possible but the odds are not in your favor. Treasure hunting is like that. Even when I am digging on my claim where I know there is good minerals all over the place I sometimes come home empty handed from a trip. I don't mean to discourage you at all. I hope you can find some diamonds. I would love to see pictures of any finds you do make even if they are just garnets. thumbsupsmileyanim.gif I have been thinking of trying some streams in the diamond fields but it may take lots of work and testing to find a good one. If I make a trip to the diamond fields I will post results here.

When I was prospecting my Stateline Mining District targets more than a decade ago, it was during a very long drought. The lakes that cover the pipes had significantly lower water levels than normal. This allowed me to take samples to determine if KIMs were present that otherwise would have been impossible to collect.

All the natural lake water levels are well above average depths due to the recent flooding that took place in the Poudre River watershed. It will be difficult or impossible to recover proper samples from the Stateline District lakes until the water levels are again reduced. The best chance for prospecting, in my experience, is to work the streams until the lake levels have dropped.

Best of luck in the New Year!

Hello fellow prospectors! I'm very new to the site and new to Colorado! Though I've just recently moved here, I've visited several times and have a huge interest in the state line district. I'm sure I've done much as others have, read everything about the district...all of Dan Hausel's books and papers, looked at Google Earth for hours!! I've been up to the area to peek around. I live in the Fort Collins area and I'm looking to connect with fellow prospectors. I feel like I have SO much to learn and I'm extremely passionate about rocks! I'm hoping to connect with like mind friends and have some adventures this coming season! Cheers

Hi Erica! Welcome to the forum and to Colorado! You lady, have come to the right place. I feel free to ask anything and I'm sure someone will have a good answer!

Posted by: EJJ Jan 2 2015, 01:38 PM

Thanks for the welcome! I would like to say one great aspect to look at when searching for diamonds in the state line district is that there has been 2-4 thousand feet of erosion since the time these kimberlite pipes were created. The pipes that have been found to be diamondiferous have had most of the pipe eroded away by the time they were even found. ie diamonds rolling around everywhere! lol... I think a good place to start when looking for placer diamonds is to study up on paleodrainages. Where did water flow during the time at creation of these pipes? Where would placer diamonds potentially be carried to millions of years ago. Could there be a concentration of them there now? Possibly!

Hello Erica! Welcome!
I think old water flows and glaciers could have moved many diamonds around and deposited them in seemingly unlikely places around the source.

Hi, y'all! I'm Rocket's partner. We have had a great time researching land records (I do this as part of my 8-5 job). We've been doing it on the State Line District for about 6 months now. Both Astrobleme and Dan Hausel (in his two bulletins, 11 & 12) have been very encouraging, suggesting we don't have to drill kimberlites to find lots of diamonds, just "pick them up off the ground"' or dig in a streambed ("there's lots of diamonds in ******* creek"). (I've seen that photo of the double handful of diamonds. Is this for real?) Logically, in creeks below kimberlite lakes and on public land seem the biggest potential for gemstone finds. We were both wondering, however, how deep you have to dig in a typical mountain stream at 7,000 - 8,000 feet to get to those choice minerals? Are we talking 3 feet or 30 feet? It also appears on the land records that there are a lot of closed claims scattered about. Does this mean they were mined out? Or did those enthusiasts from the 2008-2009 diamond rush just get burned out and discouraged? We're still planning that August (or maybe July) vacation, and are wondering what affect the 2013 floods had on the mountain streams and roadbeds? Are many still closed? It's been great reading all the posts and getting a growing education on the life of a Colorado prospector.





Hi Somethin' Else! When prospecting the streams for diamonds, think like you would for looking for gold. Diamonds are heavier than quartz and granite derivatives, and they will settle out (deposit) just like gold, but since they are not as heavy as gold, they may travel further. I tried this thinking and found a "honey hole" around Labor Day last year. For just a few hours work, I pulled out 42 diamonds, from Roosevelt National Forest area. Most of the diamonds I found, were in the 3 5gal buckets I filled to take home and pan later. They came from a creek where it exited out of a canyon into a small flat valley, it was where the stream velocity suddenly diminished that the diamonds were deposited in a small sandbar. I am going back there in July and spend a few days finding more. Attaching a picture of a .15ct sparkler from that batch.

And astrobleme is right on with his aadvice... Just a note to a post from 2008... another way to ffind diamond possible areas, is to use geological maps and look for ring dike complexes. Stateline district is one example, with the Virginia Dale ring complex. Diamond pipes occur within and adjacent to where fault lines cross these ring faults. The kansas kimberlite are associated with a similar structure...but no diamonds found. Another example is the ring dike complex located just west of the Cumberland Gap on the Kentucky Viirginia border.. One of the known kimberlite locations in Kentucky is on a fault that intersects ne edge of that ring faults. Diamond exploration there found no diamonds, but if you interpolate history of streams,, which now flow paralel to the mountain folds, in the past, they cut through the cumberland gap... which would make that kimberlite pipe, now very eroded, the likely source of several diamonds found in Virginia. One was found on a hillside just above a creek that drained from the cumberland gap area. Ditto, for the one found in Richmond, above a river that traces its source back to the Cumberland Gap area. Just think outside the box using current geology knowledge.

Just 'cause no diamonds were found in the drillings doesn't mean they ain't there.

The lamproites of the Wasatch Uplift just west of me have had instances of microscopic diamonds and indicators as well as PMs and indicators for those. But while you may not make a living off of it, on occasion mineable concentrations have been located (just nothing diamond yet).

Addendum to that .15ct sparkler... if you look close, on left side from top to bottom you will see cleavage line visible. There are 2 more cleavage lines visible if you look closely. And, yes, diamonds can have conchoidal fracture if broken under stress, but rarely happens, but this one exhibits one such fracture. Wonder what big diamond this chip broke off of.

An update to conditions for prospecting/mining this spring...2015.

A colleague told me that he was talking recently with some loggers who are working in the forest at State Line Mining District. They told him about an encounter with some folks using a sluice box in a remote stream where they were cutting trees. Evidently, the miners had recovered numerous diamonds and they excitedly shared the news with the loggers. extra_happy.gif

There is plenty of water for mining or prospecting at the present time. I would encourage anyone seeking diamonds to take advantage of these prime conditions before runoff is over. emoticon-misc-004.gif

Recently, Bobbie Askarson from Longmont found an 8.52 carat diamond worth $1,500,000.00 at the Crater of Diamonds State Park in Arkansas. She said it looked like a quartz crystal and she only was looking for about 20 minutes before she found the stone.

Once you see a natural diamond, they are much easier to spot while prospecting. I'd bet Bobbie would be good at finding gems at the State Line Mining District here in Colorado. emoticon-misc-004.gif

Posted by: Diamond Digger Jul 7 2015, 02:36 AM

Astro who priced that stone? They are living on Colorado where that stuff they smoke is legal hehehehe
A D color 8.52 stone will cut out to about 4.49 +- carats cut stone and the value is if the stone is (Internally flawless and spotless) IF LC 4.49Ct = $405 460
Below is a link to diamond price lists both cut and uncut.

Now if she is to sell this stone uncut she can expect around $150 000 to $180 000 as a rough stone the buyer will then cut it into two stones a major stone and a minor stone, the minor stone is not worth mentioning as it will be less than half a carat looking at her stone in detail. The major stone will be around 4- 4.5 CT if it is a D (Blue-white) stone and perfect price is as above but if the color drops to f, g, h, i, then the price drops by huge chunks.

The buyer then sells the stone to a wholesaler that then manufactures the stone and he in turn sells it to a Jeweler where one would go and buy it.
So the buyer will sell for $250 000 the wholesaler will sell for $350 000 (Now it is a ring pendant etc) and the jeweler will sell for $405 460 or a bit higher.

Here is the link:
http://www.ajediam.com/diamond_price_quotes.html

So the price all depends on the four C's Color Cut, Clarity and Carats.
A fancy color stone may reach that price but then it will have to be sky blue or maybe Red but both of these are very very scares like Chicken teeth!
Have fun!

Hello DD,

That diamond price link is great information for common stones. I'm not sure who valued the Crater of Diamonds find but I'm certain that the provenience increases the value substantially. emoticon-object-018.gif

Hi folks,

Thank you all for your generous contribution of knowledge to one of my favorite subjects - raw diamonds!

Having been mining at the Prairie Creek Diatreme (Crater Of Diamonds State Park) the month before that beautiful 8.52 carat find was made, I feel I might be able to shed a little light on the parks unique diamond values. As the 5th largest diamond ever found in the parks history, it is an under statement to say its worth a boatload!

For those of you not familiar with the diamonds that come out of this pipe, here's a bit of info to chew on. These diamonds are considered to be 11's on the scale of hardness, they are considered to be the hardest diamonds ever found. There are a couple institutions, one in Texas, the other in northern Arkansas, that almost always outbid anyone interested in purchasing finds like this. and yes, bidding wars do occur. Remember this is the same pipe that the 40.42c Uncle Sam, the 34.25c Star of Murfreesboro, and the 27.31c Howell, came from. And also, the home of the Strawn-Wagner Diamond. Found in 1990 by Shirley Strawn and weighing 3.09 carats when found, it is known as one of the worlds most perfect diamonds, graded a perfect 0/0/0 by The American Gem Society in 1998 and graded perfect by the Gemological Institute of America, making it the first diamond ever to receive such an AGS grading. The diamond is considered a one-in-a-billion, according to Peter Yantzer, the AGS Laboratory Director.

So, I guess that's the long way around saying the diamonds from this pipe are very, very, unique. They are, in a way, like treasure from a Spanish Galleon at auction. You can't put a nice tidy 4 c's price on them, even though that is a factor, they are worth exactly what someone is willing to pay for them!

Just my opinion, hope this was helpful.

Hello Everyone,

I was pleased to see a well written article detailing Colorado's diamond resources in the March 13, 2017 Pueblo Chieftain newspaper this morning. Dr. James Hagadorn, a scientist at the Denver Museum of Nature & Science, tells of promising new analytical techniques to gain a better understanding of the diamond crystals and the use of chemistry to decipher how Earth evolved. Perhaps this article titled “A geologist’s best friend” was also published in other papers so keep an eye out for it.

It has been many years since my last visit to the Denver Museum of Nature & Science to view the Colorado diamonds they had on display. From the photo with the article today, it appears that their collection has grown substantially. I encourage those wanting to learn more about diamonds to take a trip to the museum if they have a chance.

Sincerely,

The Crater of Diamonds State Park in Arkansas provides public access (for a fee) to mine diamonds using hand tools. Tonko Mining Company, Inc. is an entity that continues to mine diamonds using hand tools on our claims within the boundaries of Colorado's Stateline Diamond Mining District. I do not know of any other business that is currently mining diamonds for profit in the USA. That is why today's Executive Order, published below, that prohibits diamond imports from Russia is very important to my family's long term mining interests:

The US sanctions to ban Russian diamond exports has a problematic loophole. Restrictions apply to rough diamonds - but once they have been cut and polished, the country of origin no longer matters.

G7 countries buy about 70% of the world's diamonds - so a G7 ban could have an effect, if the diamonds can be traced.
