Colorado Prospector - Gem and mineral prospecting and mining forums _ Gem and Mineral Specimen Finds or Processes _ Kimberlite pipes

Posted by: leonard Feb 28 2012, 10:41 AM

Here's a little item I found on another forum.

http://www.sciencenews.org/view/generic/id/337737/title/Carbonation_brings_diamonds_to_surface



This thin slice of a kimberlite rock from northern Canada, seen through a microscope and in polarized light, shows colorful minerals caught up in magma that rose from deep within the Earth.

I use thin sections frequently but I thought it would be nice to add a "hand specimen" in here to help those prospecting for pipes to ID kimberlite in the field. Here's a pic of a kimberlite sample from my private collection. It came from a diamond bearing pipe in northwest Canada;




The interesting thing I've discovered is that some kimberlite thin sections look very much like meteorite thin sections, in a general way. Kimberlite grains are often rounded much like chondrules that are seen in meteorites. Here is a pic I just took of a thin section I have from a kimberlite pipe in Fayette County Pennsylvania;




Now compare that kimberlite thin section to a meteorite I found last summer;




You can see the rounded grains that I think are the result of high speed erosion, in the pipe on the way up, or in space when the dust grains accumulate at cosmic velocitiy. Of course this is only my opinion but it is rather interesting, don't ya think?

I'm ready for a trip to northern colorado whenever anyone that knows what they are doin wants an assistant.

Leonard,

If you are going to northern Colorado, rather than northern Canada, then this is the type of kimberlite you'd want to find...

Hi,
Pictures of the land on top of a Kimberlite Pipe (Yellow ground) in Africa.
Years ago I found the pipe by accident had it tested and was pleasantly surprised.
The room was 14c the electron microscope showed the tiny diamonds and all the important indicators. I was smiling from ear to ear and the Geologist was sweating! He asked several times where I found the sample and was pretty upset when I refused to say!
Now if only I had the money to start the mine!
Have fun
DD

DD,

Having the pipe so close to a water source should cut mine development expenses significantly.

Astrobleme
Yeah very true and there is about 100 000 tons of alluvial material right on top of the pipe so one can start mining as soon as the Washing pans are set up. Takes about three days to set up..
Then once the loose gravel has been removed you step in with brooms and brush the rock clean this is where you find almost all the diamonds that was released out of the Kimberlite.. big paydays hahaha
Then you start blasting and crushing.... I can smell the diesel fumes already emoticon-misc-004.gif
The area is well known for the large stones, if you hear of a 200 ct stone found in Africa this is the area...
Greetings.
DD

Posted by: Diamond Digger Apr 16 2014, 08:09 AM

BTW,
Thought I would mention it.
Diamond mining does not use a lot of water at all! I used to run two pans with about 500 liters of water per day.
So water is not such an issue you can fill up a 600 gallon tank at home and tow it into wherever you are working every day!
Have fun!

Caveman: Not mining it, since the ANC took over South Africa, they have brought in laws that allows them to take your mine away from you and pay what they see fit. So there are 2 very rich Kimberlite pipes in Africa that will not be developed and the locations will probably die with me, that is if I die have no intentions too hahaha.
But I am meeting with a group of Investors this week after long negotiations and if all goes well I will be opening a diamond mine soon. But not in South Africa, since 1994 70 000 white Farmers and their families have been murdered there under the ANC rule I do not aim to become a statistic.. Check Farm murders on Youtube if you have a strong stomach.

well you could always sell the info to the location to the highest bidder with a confidentiality contract not to divulge any info to anyone. a bird in the hand is worth two in the bush!

Posted by: Diamond Digger Aug 30 2014, 07:41 AM

Hi,
SA just passed a new law so that they can take any mine they want.
So that makes the pipes worthless.

DD,

Looks like you are onto a deposit with characteristics of the State Line Mining District. As far as I know, all kimberlite pipes in the district carry diamonds. Now you just have to wash the gems out of the sticky blue-green mud.

If you are in a crater lake setting, then the diamonds and garnets will be highly concentrated over the eons of wave action as they cannot wash out away from the pipe diatreme that is surrounded by granite walls. If you are in a stream setting that is cutting across the pipe, then the diamonds will concentrate as other heavy minerals do. They are just harder to collect the further away from the pipe that the stream travels. I've attached a photo of a stream that is developing a placer containing the blue-green clay that I discovered 10 or 11 years ago. You can see the close resemblance to what you've found.

I certainly am excited by the looks of your pit photos.

Congratulations!


Posted by: Diamond Digger Jul 6 2015, 03:40 PM

Astro,
As it is this deposit is quite some distance away from the state line, but so far the test we ran looks good, waiting on the bulk sample permits then we will give it a good going over.

Like your picture, that looks like a run to me, meaning the lava flowed away from the pipe and formed a thick layer of kimberlite that's now in the weathering process. Needs sampling!!

One of my young guys stumbled across this a few days ago... tested it. Diamondiferous Kimberlite exposed right on top of the ground.
Of course it is now claimed done and dusted.
Onward's and upwards!
Cannot wait to get my teeth stuck into this bit!

New to group and am hitting the ground running.

What I wouldn't do to get DD and Astrobleme in the same room give them a topic for discussion and then just sponge it all up. DD I spent two stints in Southern Africa. Once studying black rhinos in Namibia and again working with Southern Ground Hornbills in Northern SA and Kruger. I have friends that still live in fear because of the violence and land reparations. Seems like just about everybody loses out...the people, the land, and the wildlife...sad. A piece of me will always be in Africa and I can't wait to be able to go back.

But back to happier things, those "indicator minerals" on the ground in the second picture, is that what I think I've read other people referring to in other posts as lava ash? Is this correct? Are these like xenoliths or do they form in the kimberlitic process. I'm so new to this and have been just read, read, read, reading and hound, hound, hound, hounding. I'm looking for heavy and shiny things wink.gif , but also keep anything that looks out of the ordinary along with location in case later if/when I learn more, I can go back to sites I may have been too ignorant to know they were good in the first place lol. This seems to be the case with these. I found very similar looking stones in the past but because of how far back in I'd hiked, I only took a few small ones and snapped a gps point. Now of course I can't find the stones I took, but I have the gps and I don't need it because I remember right where they were. Tell me if I'm wrong or over-simplifying but to me they felt and looked like green, purple, yellow limestone that got thrown into lava for a bit, partially melted, and then yanked back out.

Thank you so much and I look forward to learning more.

Musk Rat,
Welcome to the forum!

Well what you suggested has been done! Astro and I have met and been together in my truck looking at possible Kimberlite pipes.
Was great meeting the guy even though our trip ended up with no Kimberlites or indicators found. Cost me a pretty penny but that's all part of prospecting.
That trip I did manage to find a kimberlite pipe and managed to secure it.



Here is Shea one of my guys sitting on top of the exposed Kimberlite




When prospecting for diamond bearing kimberlites this is what you are looking for, G 10 Pyrope (fire) garnets and Chromium diopside (green) crystals.
These have been weathered out of the host rock.




This is what they look like still in the host rock Kimberlite.



And the real thing you are looking for!


Hope this helps!
PS the light green CR crystals are very brittle and only travel about .75 miles away from a pipe in a river setting, before its crushed to powder.
So if you find them you are close!
DD





Posted by: Musk_Rat Jan 31 2021, 09:02 AM

Hey thanks for the reply Diamond Digger. What a trip just finding that pile weathering out of the host rock drool.gif . I haven't gotten that close, but have some very interesting things I've found while panning a few waterways up there. The fires (and my day job) made it really tough to get much done on public land this past season. But I'm excited to explore some targets more thoroughly and see what this summer brings.

Then what I hear you saying is don't bother looking for anything else other than what you pictured lol.

Specimen 1: I found this specimen in river gravels while panning and it stood out because it felt like glass in my hand and was very heavy but was covered in river scum. And honestly I wish I could say I'm some geological genius, but really I kept it because it was very heavy and different than anything else I'd seen. As well, I could feel the circular indentations you'll see on the one side of the stone. I'm hoping this wasn't the stupidest thing I could do but I used diamond polishing pads (for polishing marble counter tops) to clean it up to better see what it was composed of. Once I started to see what I had, I decided to stop in case I was ruining the specimen or doing something stupid. Additionally, it wasn't taking well to the polishing (very hard material) compared to other stones I'd polished in this manner.

The first two photos are with my phone. Then the rest are with my digital microscope. The last photo you can see the pyrope shining through the blue mineral (kyanite?, eclogite?)

Thanks for the help and anyone else out there that could shed some light.

Another one of the back close up.

 

Posted by: Diamond Digger Feb 2 2021, 02:17 PM

Hi MR,
Looks like you have some form of Garnet in that one specimen however its very unlikely to be Pyrope garnets as they are only formed inside Kimberlite.
The other rocks looks interesting, not something I have seen before.
And yes haha don't bother looking for anything else if you are looking for kimberlite. There are a few in Colorado but the diamond bearing ones are all tied up and off limits to everyone.
However if you are keen you can look in this area 39° 4'34.29"N 105°16'33.17"W in CO there is rumoured to be a diamond bearing pipe there in the area... You have samples of what to look for go get it!
Very good luck, lots of water and food off the 51.
Have fun
DD

Posted by: Musk_Rat Feb 2 2021, 07:43 PM

DD,
Thanks for the input. Colorado School of Mines holds "office hours" periodically for the public where you can bring in samples for a geologist to look at and help id. I may try that, but from my own research, the only thing I can come up with is that it's an eclogite nodule.

https://en.wikipedia.org/wiki/Eclogite

How it got to where I found it is probably up for debate. Definitely going to poke around more in that area. I know that all the "KNOWN" worthwhile kimberlite has been claimed up in the area and/or is behind miles of litigation, private land, and barbed wire. However I know this beautiful women that lives up there and has been milling kimberlite for millions of years, but I just need to figure out where she sorted it all to...

Thanks for the coordinates! I am very keen! Some close family lives not to far from there, so now I have an excuse to visit and an excuse to leave!

Did some poking around on aerial photography and on macrostrat.org [(if you haven't seen this website you really should). It's a geological map of the whole world. The map is only as good as the source data so I imagine it's more accurate and useful in some areas than others. It can be tough to navigate and find your area of interest, but once you do... atomic.gif ]

From what I can see from the air, there's promise in the area (and unclaimed areas from preliminary checks)! Thanks again DD!






Posted by: Musk_Rat Feb 7 2021, 04:10 PM

So I've done some more research just about rocks that carry garnets and I think the one specimen might be Garnet Blueschist. Very cool and I'll take into consideration any other input. From what I read it is very similar to eclogite but is found less deep in the mantle. However similar to other Kimberlite xenoliths if it isn't exhumed quickly the minerals will be altered on their way to the surface.

Posted by: Diamond Digger Feb 8 2021, 04:18 AM

Musk Rat,

Kimberlite is a very peculiar rock once exposed to oxygen for a few million years it changes from hard rock to a yellowish sand like structure very similar to sandstone in colour. (weathering)... hence the term yellow ground. It will react with oxygen and the slightest water movement will wash the material down any close-by gully's ditches rivers etc... now the name changes to Alluvial material and this material can travel for hundreds of miles downriver.... Many of these ancient deposits are mined in SA and around the world.
So Kimberlite weathers when oxygen is introduced..... it releases the Pyrope garnets G-10, Chromium Diopside diamonds Spinel etc etc.... all these are called diamond indicators.
But Kimberlite comes to the surface from 150km down in the Earth.... as a big hot lava flow and collects quite a few different rocks on the way up. So you will find strange rocks in it nothing out of the ordinary.
Good luck with your hunt.
DD
PS there are lots of different garnets.... but only One counts!!

Posted by: Musk_Rat Feb 10 2021, 10:19 PM

Yeah DD the more I research this is a cool rock and they're garnets, but like you said not the ones that count. Looks like more digging and more miles...Thanks again DD. Now if the snow would only stop falling.

Posted by: Diamond Digger Feb 11 2021, 04:38 AM

Snow? LOL Diamond miners are made of sterner stuff..... Road to work!



Build in cooler box!




Cleaning the windscreen a light snow dusting.... GMF




As you can see we don't care much about a little bit of ice....The only good ice is them ones you can put in Whiskey
The rest one ignores!
Get out there and do the thing! lol

Posted by: Musk_Rat Feb 11 2021, 07:05 PM

Love the pics! Too good! I think it's safe to say you're much further along in the process than me, but just as crazy lol! I'm just getting on the scent. It's funny because I've been wondering if you are in SA or the states and that answers that question. I was out and panning/sampling just last week after work.

You should be a motivational speaker! Those are incredible!

Posted by: Diamond Digger Feb 14 2021, 02:40 PM

Musk Rat,
Do not forget to take pictures of the area and stones that you find at the co-ordinates, we are waiting anxiously for your picture report here.
And make sure there is still snow on the ground.... emoticon-object-024.gif
Your Key is to find Chromium Diopside crystals, once you do you know you are .75 miles or less from the pipe.
Anthills are a good place to search for CR and G-10... you will not find small diamonds in any anthill, their little paws just cannot pick a diamond up since they are all covered with a natural oily layer...
Very good luck!
DD

If you find it Claim it get the permits in order and I will bring the gear.
DD

Posted by: Musk_Rat Feb 15 2021, 10:59 AM

DD,
A couple spots will have to wait until spring thaw because they're locked under ice(more now than ever after this polar weather). I'm also anxious to head up to that other area I alluded to, but it's a good trek in even for the highly motivated. I'll be headed West and back on the trail asap. (My wife and I just welcomed our first child 3 weeks ago, but she knows I can't stay out of the hills long) There will no doubt be plenty of snow still and if I'm lucky some ice. I'm no geologist and I don't want to get your hopes up though. I know I'm on the right track, but how close to the finish line?

Posted by: Diamond Digger Feb 16 2021, 08:56 AM

MR
Congratulations on the Kiddo!

One only have hope once one is in the field looking for the tell tale sign that gets your blood pumping with a question.... "What If?"
That is the good feeling when it turns out to be the indicators that you suffered snow Ice and bad winds to find.... Makes the hart warm.
Good luck

Hope you get some sleep!

Travel safe my man! So sad to hear about SA... Luckily my friends live and work out in the bush, so are more worried about things with teeth lol. It's just probably starting to get cool down there and mean while we're in for a weekend of nice weather(I did go up last weekend, but mostly to prescout and stretch my legs), so I'll be strapping on the ol boots and heading West. Hopefully I'll have something good to report or at least know a little bit more than I do now.

Drink a black label for me! cheers.gif

DD still haven't made it to those coordinates you gave me, but have been relatively fruitful in a couple other locations. Been prospecting until just a couple weeks ago, so now have been going through samples more closely from the summer and took some photos. Here are some indicators from my last area of interest.

MR,
Hows things....
No idea what indicators you got there but yeah.... its not for diamonds or Kimberlite.
Diamondiferous kimberlites are very very rare. If you do not have the Coordinates it can cost Millions to find the right place.
Dont give up.... Everyone learns the hard way!
Maybe just follow the instructions go to the right spot.... (LOL)

DD,
Things are good. I did at least do some land status research for the area you sent me and will eventually get up there. Seems like the small garnets I'm finding are green/red/purple/orange just like yours but not as big. Thoughts? Are they different?

How have your efforts been this year?

Those look like some nice indicators to me Musk Rat! Keep up the good hunt. signs021.gif

Posted by: Diamond Digger Jan 12 2022, 10:49 AM

Good stuff,
However the picture above only have G-10 Pyrope garnets and the green crystals are Chromium diopside not garnets.
The garnets is also know as Fire garnets very dark purple/red....
Do not confuse granite garnets with G-10"s.
Get out there and get it done!

Hi MR
Nope do not recognise that type.
There are no quarts associated with kimberlite indicators.
Have fun out there!
Not easy to find diamond bearing indicators......
Major mining companies spend $$ millions a year trying to find them.
You got the spot you got the info..... Once you start washing that topsoil you will see the indicators I gave here.

DD,
I appreciate the insight. Not what I wanted to hear but I still appreciate it. Peer review is the hardest thing to swallow sometimes, but is important to keep you honest and on the right track. I wish color was the only important identifying factor. I saw purple and got very excited, but overlooked the possibility that it could be some other purple mineral. I have still set them aside to be potentially tested and haven't given up that they could be purple garnets, but they could also be little amethyst chips instead of little garnet chips.

The search continues and I'm not giving up on my spot. I'm finding everything that points to a deposit except the right minerals to convince you lol(wet/depressed area, blue sticky mud, variety of minerals nodules that don't belong there, but there is a creek cutting across/through it so there are upstream minerals mixed in)

Thanks again DD and I'm going to check out your area this spring.

Posted by: Diamond Digger Jan 30 2022, 02:31 PM


MR,
Yeah it is easy to convince yourself something is close by however the minerals do not lie as they only come from one source.
Chromium diopside is a very brittle green see through crystal, you can powder it to dust between your fingers. They do not travel far from a pipe, about .75 miles then they are absorbed in the dust. Once you find such a crystal then you are so close!
Very good luck!
DD

I'm finding everything that points to a deposit except the right minerals to convince you lol(wet/depressed area, blue sticky mud, variety of minerals nodules that don't belong there, but there is a creek cutting across/through it so there are upstream minerals mixed in)

Thanks again DD and I'm going to check out your area this spring.

Musk_Rat,

When I compare your pics to the one of known indicators from the Sloan 1 & 2 diamondiferous pipes in the Stateline Mining District from Dan Hausel, there is very close resemblance IMO. Take a look at this post;

Here's the indicator photo I'm referencing...



Here is my opinion of the comparison of photos...




Sincerely,

Astro,
I was curious if your were going to weigh in and happy you did. That's some pretty slick work with the pics and very compelling. From my previous post: "I'm not giving up on my spot. I'm finding everything that points to a deposit except the right minerals to convince [DD] lol." "I have set them aside to be potentially tested and haven't given up."

I am continuing with optimistic scrutiny and some valuable perspective. I believe getting them lab tested is the only way to know for sure outside of finding a stone in my samples. I appreciate the feedback and knowledge all around.

MR...
I mined diamonds from 8 years old.... there are only one set of indicators for a Kimberlite pipe or its vicinity, these I gave you in the PM.
I know Astro very well we met in Colorado when I was over there prospecting. I tested his claims but never found anything real no G-10.s no chromium diopside...
and well diamonds are very rare. I even paid $500 for the privileges' to test his claims at the here mentioned locations.... but nope there were no diamond indicators at all unfortunately. He is a nice guy and I would really have loved to find the right stuff on his claims but nope nothing... I even tested drill samples from an Australian company that drilled there and found nothing. Not every Kimberlite have diamonds... its a hard but cold fact.
However it is not easy to convince a convinced person of facts..... I never mentioned this, will be the first time I bring this out, most people get very caught up into the idea of sitting on a fortune but alas it only ever pans out in about %1 of the cases.
However if you think that purple amatists is a diamond indicator I cannot do mush to convince you otherwise but experience will eventually do the job for me!
So hard reality knocks.... diamond indicators are very specific... if a kimberlite does not have 23ppm (Parts per million) of Chromium diopside and an abundance of G-10 pyrope (fire) garnets it is bare... nothing there no matter how hard you wish for it.... done.
Sorry I had to crush a few dreams here but diamond mining is very very specific.... you either have the correct indicators or you waste money on useless claims.
DD
I know I am going to be unpopular after this post but I know my business... it is diamond mining.

DiamondD,
No worries man. I appreciate your honest thoughts as always. It was not my hope to stir anything up and I can take the feedback. To me this is science and facts are facts...it's either there or it isn't. I will continue to dream, but leave guessing and hoping out of the equation. I'm seriously looking into getting them lab tested and for a few hundred bucks can definitively find out.

Diamonds and kimberlites are extremely rare, but so am I lol (1 in 8 billion) I knew this wasn't going to be easy and something I may never succeed at, but I will leave you with one of my favorite movie quotes from The Edge..."what one man can do, another can do!"

DD stop.gif ,

I was concerned about what you were up to when you contacted me expressing interest in my company's mining claims. This concern was amplified as you bragged extensively about your brother-in-law being upper management in DeBeers. But when you told me that you could provide access to a machine that could extract diamonds using only 2 liters of water per day, to get the diamonds out of the thick clay on my claims, I gave you a chance at the very reasonable rate of lease of $500. However, you failed to prove your ability as professed, and the lease expired. I sincerely understand your continued interest in the Stateline Mining District and don't think your post will make you unpopular. My company considers proposals on a case-by-case basis, and we encourage you to work with us rather than against us and all of the other prospectors working in that area.

DiamonEx, that Australian company you referenced, never provided the drill core results as I was contracted to receive, yet you say you tested them? This revelation, along with the timing of it is, well...very interesting.

At least you learned to drive on the right side of the road during the day that we spent together. smiley-laughing021.gif

Hope your search for diamonds is successful as it is a very fulfilling experience! cheers.gif

LOL yeah I have no interest in the claims you have there. Sorry. I went to test them in case there was something there. There was nothing.
No matter how good an ability is, it just can prove anything if the claim is bare.
Nothing there Nada zilch.
And I will refrain from saying anything else. Just that you are wasting a lot of money on barren ground.
Have fun.

Just started the process getting the mine up and running.
Got some time
