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

![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() whell the other day I may have located a very ridiculously large sized kimberlite pipe in Colorado. This may or may not be a Diamondiferious kimberlite , but am positive its related as I found many Xenoliths inside this pipe. The xenoliths found inside arent the conventional Indicator Minerals, But for sure came from an unknown depth and are present on the surphase. It apears to have eroded to the usual blue soils mainly Chlorite and montmorillonite clay, in this picture you can see sodium carbonate on the granitic rocks in the lake, another characteristic of kimberlite there is no source of salt ANYWHERE in this granitic basement, This might be a kimberlite , im not certain but will know shortly as im contacting the best , If a kimberlite , would prove the largest pipe in The USA Bennie

Sincerely, Tonko Mining Company, Inc. http://www.meteoritecrater.com/ yep i sure wouldnt want to trespass on anyones claim! i imagine theres enough of that as it is!but the information given here has been really enlightning to read and research about. ive seen some of these indicator materials in a sand and gravel plant that is getting its material from the anceint Mississippi River channel at 130/150 feet down and 5 miles from the current river channel. the close up colored pictures have helped educate this old man! and i say thank you for that! |
