In 1975 diamonds were accidentally discovered in wyoming, to date there has been over 300 kimberlites discovered between colorado and wyoming. Atleast 200 discovered by Dan Hausel while he was chief of exploration.
since 1980 many properties have seen or visited by companies , most if not all have yielded diamond. In the begining cominco desighned a terrible mill and as a result many Diamonds were lost. last year one ton of tailings were re processed for diamond content and no suprise to dan hausel a 4 carat diamond was recovered.
These diamond bearing rocks called kimberlites can be located through many exploration techniques. one of the most popular is looking for indicator minerals ans these tell a pro theres a kimberlite nearby.
another popular technique is a fly over with special mounted equipment made especially for locating these anomolys. Myself I use one of the best techniques "keeping my eyes peeled to the ground" one would want to see blueground; eroded kimberlites and source of indicator minerals.
once a site is located , sampling is generally the first thing. Mining companies sample anywhere from .5 of a ton to 300 tons . ore grades in the state- line district varied from .1CPHT to 135.cpht (carats per hundred tonnes, tonne=200lbs more}
but again cominco lost diamonds they desighned 3 mills each more worse than the previous . Numerous indicator mineral anomols exist in colorado and wyoming > after Dan discovered 200 kimberlites for Diamonex, he told me theres still many discoveries to be made on both sides of the border.
most if not all kimberlites in the stateline district are infact owned thus off limits.
Canada started mining a few short years ago and are now number3 in the world. Canada even produced more than Africa last year. Fact DeBeers sold all properties in Africa and are exploring thier new sites in Canada which are considered "WorldClass". Myself I have 20+ excellent targets to follow up on and will keep the CP's site fresh and keep you guys updated

Since I deal with a lot of mine owners here in the South-east I have seen first ahnd how tresspassing can hurt or hinder your mining and prospecting. I am sorry to hear about that Mr. Tonko. Out there you guys have so much land that it would be hard to differenciate between someone's claim and public land. You really have to know where you are at so as not to step on anyone's toes. Is there a map you can get which shows where the claims are? Here in GA and most places have fences and or NO TRESSPASSING signs around property but that still doesn't stop all tresspassers. When my friend used to work JXR amethyst mine he would cover as much of the area he was working in with dirt and the trackhoe but he couldn't cover it all. He would tell me stories of chasing off people who would sneak in all the time trying to dig and steal from him. It was easy for somebody to sneak on the property and dig and they just might have pulled out a 5000 dollar crystal or a 10,000 dollar cluster. I guess it doesn't matter where you live because there is always somebody who will break the rules. Hell, there have been claimjumpers since gold was first discovered. Usually if you find someone on your property like that you have to give them a warning as it could be an honest mistake but that second time ole Mr. sheriff needs to come on out and he will straighten things out.
