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

Hi Everyone:
I certainly have no problem with exchanging information and promoting prospecting as I support those efforts with membership in several organizations including the Colorado Prospector club. On the otherhand, I have no respect for claim jumpers. Here's a set of photos detailing the excavation of sand samples and blue clays that were being collected without my permission from one my company's diamond mining claims this past summer. [attachment=3010:claimjump.jpg] [attachment=3011:claimjump2.jpg] [attachment=3012:claimjump3.jpg] [attachment=3013:claimjump4.jpg] If anyone has further knowledge of this instance or any other incident of claim jumping efforts against my mineral right ownership, please let me know.
