Multiple New Sulphide-Rich Mineralized Structures Identified In Resource Expansion Drilling At Stillwater West

VANCOUVER - Stillwater Critical Minerals Corp. reported on diamond drilling completed at the Stillwater West Ni-PGE-Cu-Co + Au project in Montana in 2023, and other initiatives. The 2023 drill campaign focused on expansion of the NI 43-101-compliant resources with particular focus on expanding recent high-grade discoveries at Chrome Mountain at the west end of the nine-kilometer-long resource area. Six holes totaling 2,310 meters were completed within and outside of the current resource area, west and south of the current DR-Hybrid deposit, as part of a planned multi-phase program. Multiple new mineralized zones were intercepted.

Results include identification and expansion of the N series of sulphide-rich mineralized structures parallel to high-grade nickel sulphide mineralization first discovered by the Company in drill holes CM2021-05 and CM2020-04. Drilling in 2023 intercepted the N2 and N3 mineralized zones in parallel to high-grade mineralization in CM2021-05, which is now known as N1. Reported prior, N1 returned 13.2 meters grading 2.89% Recovered Nickel Equivalent1 ("NiEq") (2.31% Ni, 1.51 g/t 4E, 0.35% Cu, and 0.115% Co), starting at 37.6 meters and is contained within 400.8 meters of continuous battery and precious metal mineralization. N series structures and associated high-grade mineralization are now understood to be part of a series of north-south trending structures that crosscut the layered sequence and Platreef-style mineralization of the Stillwater Igneous Complex.

Drilling also confirmed nickel and copper sulphide mineralization in a large and previously untested geophysical anomaly which forms part of a string of untested anomalies extending over 12 kilometers along strike. All core has now been submitted to the lab for assay with results expected soon. Mineralized zones were predicted by the updated exploration model, demonstrating the Company's success in advancing the first ever detailed geologic model of the lower Stillwater Igneous Complex. Drilling for 2024 is now being planned to continue expansion around known mineralization at the existing resource areas, at recent discoveries including the N series structures, and also more broadly across the 32-kilometer-long project.

Michael Rowley, President and CEO, said, "We continue to advance new sulphide-rich discoveries at our flagship Stillwater West project as we apply geologic models from South Africa's giant polymetallic nickel sulphide mines to similar geology at our Stillwater West project. Recent work is identifying additional styles of mineralization, and we look forward to expanding further on these exciting developments as they advance. Overall, the Stillwater district remains underexplored - and therefore wide open for significant expansion of known mineralization - despite having produced critical and strategic minerals such as nickel, copper, palladium, platinum and chrome for over a century. We look forward to reporting assay results and providing updated analysis as we work with our partners at Glencore PLC and the US Geological Survey to advance primary domestic supply of nine of the commodities identified as critical by the US Government. Additional news is expected from our Kluane and Drayton-Black Lake projects, carbon sequestration studies, and other initiatives including continued work on government funding channels."
