Strathmore Plus has acquired the Agate claims, an in-situ recovery (ISR) project in the Shirley Basin uranium district of Wyoming. The 52 lode mining claims were staked in an area previously explored by Kerr-McGee Corporation during the 1970s. Kerr-McGee was the largest uranium company in the US at the time. Uranium mineralization is contained in Wyoming-type roll fronts within the Eocene Wind River Formation, an arkosic-rich sandstone. Historically, 60 million pounds of uranium were mined in Shirley Basin, including from open-pit, underground, and the first successful in-situ recovery operation in the US during the 1960s.
Technical Advisor, Mr. DeJoia, stated, “During my 10 years working in Shirley Basin, I was aware of the extensive exploratory drilling that Kerr-McGee was completing across the central and southern Shirley Basin areas. On occasion I would visit the drill sites, where I had a chance to see the shallow depth of the drilling and notable changes in the color of the cuttings distinguishing altered from unaltered ground, indicative of roll front mineralization in Shirley Basin. The area is readily accessible from the state highway with utilities crossing near the claim group also. Shirley Basin has excellent transmissivity and permeability, ideal for in-situ recovery. We look forward to exploratory drilling in the near future to verify the historical drilling results and to expand the area of mineralization into untested ground.”
The Agate property consists of 52 mining claims covering 1,075 acres. Kerr-McGee drilled at least 500 holes in the area covered by the claim group. Strathmore will acquire data for 100’s of geophysical gamma logs and associated drill hole location maps for the property area that are available from the Wyoming Geological Survey. The uranium mineralization is shallow, from 15 to approximately 150 feet deep. Much of the mineralization is below the water table and is amenable to in-situ recovery. The average thickness varies from several feet to tens of feet, with grades ranging from 0.02% to 0.18% eU3O8 as noted on the historical gamma logs.
