Multiple Large-Scale Polymetallic Magmatic Sulphide Targets In Historic Stillwater Mining District

VANCOUVER - Stillwater Critical Minerals Corp. reported multiple large-scale magmatic sulphide targets generated from a property-wide MobileMTm magneto-telluric (MMT) geophysical survey completed in late 2024 at its flagship Stillwater West Ni-PGE-Cu-Co + Au project in Montana.

Data from the 2024 MMT survey was processed and incorporated into the Company's 3D geological model of the lower Stillwater Igneous Complex to prioritize targets with a focus on expanding current mid- and high-grade mineral resources.

Inversion and 3D modeling of results from 2024 MMT geophysical surveys provide multiple coincident multi-kilometer-scale resistivity lows and conductive highs. Magnetic inversion processing from the MMT data provides important information for project-wide structural interpretation and highlights relationships between the metasedimentary floor and ultramafic strata. Multiple very low frequency ("VLF") data were also acquired, confirming near surface drilled mineralization and structures. Limited drill testing has been completed on these new targets to date. Where available, drill results confirm polymetallic sulphide-rich Platreef-style mineralization across wide areas of the project.

Results have expanded the detailed 3D geological model of the lower Stillwater Igneous Complex that has been developed by the Company from 9.5 kilometers to 20 kilometers. Results have provided multiple priority drill targets for expansion of mineral resources with particular focus on mid- and high-grade mineralization. Drill targets are now being finalized and prioritized for planned upcoming drill campaigns.

President and CEO, Michael Rowley, said "Having relied on globalized supply chains for decades, the United States has now made clear it intends to secure domestic inventories of, and processing capacity for, nine critical minerals that we have inventoried at Stillwater West. Last week's Executive Order from the White House is the strongest directive yet in this regard, building on similar initiatives that date from 2016, and earlier. As the third largest mineralized layered magmatic complex in the world, the Stillwater Igneous Complex is famously well-mineralized and offers both scale and grade, making it a foundational component of this Government- mandated national policy objective. The Stillwater Igneous Complex has provided the United States with critical minerals for over a century, including the on-going production of palladium, platinum, rhodium, nickel, copper and other metals by our neighbor Sibanye-Stillwater. We are well positioned to bring these large, polymetallic mine models with robust economics to a similar geological setting in the United States. Following our recent meetings with State and Federal officials, we are focused on accelerating our path to mine development and production. We look forward to providing further updates."
