(TSXV: USCM) (OTCQB: USCMF) (FSE: 0IU0) (\"USCM\") and US Critical Materials Corp. (\"Materials Corp.\") (collectively, the \"Partners\") are pleased to report the results for the underground channel sampling completed at the Sheep Creek Rare Earth Project in southwestern Montana (\"Sheep Creek\" or the \"Project\"). The sampling was completed in Adit #1 and Adit #3 which were developed in the late 1950's for niobium mineralization by the Continental Columbium Company. Until now, the workings have not been accessed and evaluated for rare earth mineralization. A total of 23 samples were collected and described by the Partners, and were analyzed by Activation Laboratories (Actlabs), located in Ancaster, Canada. Highlights from Underground Sampling ProgramA total of 23 carbonatite samples confirmed rare earth mineralization with grades up to 102,293ppm (10.23%) Total Rare Earth Elements (\"TREE\") (Sample #720), including 13,940ppm (1.39%) combined neodymium and praseodymium, which are the most sought after of the Light Rare Earth Elements (\"LREE\") group.Underground results reveal an average of 50,400 (5.04%) TREE, including an average combined 6,721ppm (0.67%) neodymium and praseodymium. These grades are consistent with the surface sample results (reference press release dated February 14, 2023) and therefore suggest uniformity in the TREE content of the carbonatite bodies. The carbonatites within the Sheep Creek mine workings are strongly enriched in LREE with an average value of 5.03% compared to 121.6ppm for Heavy Rare Earth Elements (\"HREE\").Preliminary geologic mapping has tentatively connected several of the carbonatite bodies suggesting continuity over several hundred meters. The exposures sampled in the adits are likely contiguous with surface exposures, a vertical distance of about 50 meters. Expanding both dimensions will be the focus of a drilling program.The samples collected in 2022 from Adit #1 and Adit #3 are summarized in Table 1 and shown in Figures 2 and 3. Table 1.
