Fall Exploration At The Sheep Creek Rare Earth Project


VANCOUVER - US Critical Metals Corp. (USCM) and US Critical Materials Corp. (Materials Corp.) reported on fall exploration efforts at the Sheep Creek Rare Earth Project in southwestern Montana. Sheep Creek is one of the highest grade rare earth projects in the United States and the Partners have now confirmed mineralization at surface and at depth. Based on the presence of mineralization at depth, the technical team will further focus exploration efforts on these promising zones. Two of three historic adits (Adit #3 and Adit #1) have been successfully opened and sampled.

The recent program included 21 underground rock-chip channel samples, 24 surface rock chip samples, 17 surface channel samples, 30 stream sediment samples and approximately 150 soil samples. The underground workings were developed in the late 1950's for niobium mineralization by the Continental Columbium Company but have not been previously evaluated for rare earth mineralization. The carbonatite exposures afforded by the underground workings will greatly advance the understanding of this complex and unique geologic system. Results from opening, mapping and sampling of the underground workings will support the filing of a Plan of Operation with the US Forest Service. The Partners will provide more details outlining the results from the recent program and plans to drill the Project in due course.

The carbonatite exposed in Adit #3 is accessed by a cross-cut approximately 400 feet long at which point it intersects a northwest-southeast trending carbonatite that is developed over a distance of approximately 120 feet. The carbonatite in the mine workings correlate to carbonatites exposed in a trench cut 125 vertical feet above the adit. The carbonatite in Adit #3 varies from 1 foot to over 4 feet in width and is strongly banded with ancylite, allanite and monazite. Nine rock-chip channel samples were collected from Adit #3. A grab sample of ancylite-bearing carbonatite analyzed in 2021 (sample 21005) from the trench above the adit contained 17.05% total rare earth oxides.

The carbonatite exposed in Adit #1 varies from 1 to 3 feet in width and can be followed for a distance of 270 feet along the drift. Ancylite is present throughout the underground workings. Rock-chip channel samples were collected across the mineralized zone and will be analyzed for rare earths and other critical metals. 12 rock-chip channel samples were collected from Adit #1. A grab sample of ancylite-bearing carbonatite analyzed in 2021 from a surface outcropping of the dike, about 50 feet above Adit #1 (sample 21008) contained 16.44 % total rare earth oxides.

James Hedrick, President, said, "These initial underground findings further support the potential for Sheep Creek to become a truly unique and valuable asset within the US. During my time with the US Geological Survey, as the rare earths analyst, I had the opportunity to review the majority of the rare earth projects in the US. In my professional opinion, there are very few assets in the US that have the potential which continues to be uncovered at Sheep Creek."

Mr. Darren Collins, Chief Executive Officer and Director of USCM, comments: "These findings continue to support our business model of identifying teams with proven expertise in specific commodities and providing the capital required to advance those projects in a timely and impactful manner. It is a pleasure to continue to work with Jim and his team and we look forward to further results from Sheep Creek."
