Wyoming kimberlites

[dowser]

Many areas of crypto volcanic structures, can be observed, with kimberlite diamond ferrous possibilites, just west and North of Cheyenne. Seems to me a very interesting area to prospect for gems. I dont see any posts about it. Has anyone checked it out? Is it a nice place to visit, camp, explore, and prospect ?

I spent a good portion of my time, for several years, prospecting for diamonds in the Green River Basin. never found a diamond, but found lots of kimberlite-indicator minerals, like chromum diopside, pyrope garnet, and others. I met a guy from South Africa who was over here looking for diamonds. He now has several k-pipes claimed in the area you mentioned, and also near the old Kelsey Lake diamond mine. He had, at one time, the rights to the Sloan Ranch diamondiferous kimberlites, too. Don't know if he still has those rights. I left 2 sluices in drywashes in the basin. Haven't checked them for 3 years. Need to get that done next summer. Sluices aren't much good for gems, but work to some extent, and you can leave them in remote locations to do their work. Figured it was worth a try.:-)

Thanks, I knew someone woulda checked. I've learned a little about diamond ore, watching in Arkansas. I saw multiple places listed with G-10 Garnets, around N Colorado and S Wyoming. I know that the ore itself might not contain many gems, because most were resorbed if not cooled quickly. Diamonds in Arkansas are found in years of deteriorated lamphorite gravels. If a gravely area exists around their, maybe someone can get lucky. Sounds like a fun place to explore..

I really enjoyed diamond prospecting. I was always finding other gemstones, which kept it interesting. Thew diamonds are there, even in the Green River Basin, but in that basin the kimberlites are eroded down and buried under hundreds of feet of erosion debris from the Uinta Mouintains. The diamonds were dispersed long ago, but still occasionally found. There are also tons of fluorescent minerals in the basin.

Agree! just North of where you were is a ton of Jade. May not be a diamond, but still worth picking up.
