US Critical Metals Corp. announced that it has completed further exploration activities at the McDermitt Project in Nevada. The Project is strategically located along the east margin of the McDermitt Caldera and approximately 19 kilometers from Lithium America's Thacker Pass Lithium Project, which is the largest known claystone lithium deposit(s) in the US with 3.7 million tonnes of lithium carbonate equivalent reserves at 3,160 ppm lithium1. The field work was designed to examine and sample in detail the historical trenching area where lithium-bearing decomposed rock material was reported in previously collected samples, and further investigate the presence of outcropping caldera lakebed sedimentary rocks within the confines of the claim block. This exploration program has significantly advanced each of these objectives by replicating previous samples of approximately 2,000ppm Li. The map below provides sample locations and corresponding lithium values of samples collected during the Fall 2023 and Spring 2024 field campaigns. The field work was designed to examine and sample in detail the historical trenching area where lithium- bearing decomposed rock material was reported in previously collected samples, and further investigate the presence of outcropping caldera lakebed sedimentary rocks within the confines of the claim block. This exploration program has significantly advanced each of these objectives by replicating previous samples of approximately 2,000ppm Li. The recent exploration work suggests that the eastern margin of the caldera has been overlooked for lithium potential due to post-mineral cover. Samples were collected from nearly all of the trenches that cover an area approximately 1.3 km north-south and 0.3 km east-west. Detailed work within the historical trenching area where samples of lithium-bearing sandy material have been collected included reexamining the area where the initial samples were collected and undertaking trench dump sampling of nearly all of the trenches that exist in the area. During the Fall of 2023 and Spring of 2024, a total of 53 geochemical samples were collected from the trench area and surrounding areas. USCM collected 53 samples at the historic trench area and the surrounding areas (two sampling campaigns during Fall of 2023 and Spring of 2024) where highly anomalous concentrations of lithium were previously reported in several samples. All of the samples comprise unconsolidated material, mostly of sand or silt-size, assumed to be colluvial and alluvial in origin with a possibility of being derived from decomposed rock of local origin (loess deposits). Five samples out of the total 53 have shown elevated concentrations of lithium. These include sample 945910 at 2,054 ppm Li collected during the Fall 2023 exploration program, and samples collected from the current exploration including sample 945938 at 670 ppm Li, sample 945939 at 2,129 ppm Li, sample 945940 at 418 ppm Li, and sample 945941 at 754 ppm Li. The highest lithium concentrations observed were from samples 945910 and 945939 which were collected from a single ridgeline,
between two trenches, that is covered by a sandy material that hosts the lithium mineralization. The map below provides sample locations and corresponding lithium values of samples collected during the Fall 2023 and Spring 2024 field campaigns.
