Stillwater Complex Continues Trend Of Identifying Increasing PGE Content Up-Sequence


VANCOUVER - Danie Grobler, Vice-President of Exploration for Stillwater Critical Minerals Corp. (SWCM), commented, "We see an overall trend of increasing PGE content up-sequence within the Ultramafic Series of the Stillwater Complex (SWC) in Montana. Scientific studies have shown that the Ultramafic Series of the SWC are enriched in PGE relative to most mafic magmas. Furthermore, the chromitite layers correlate with and are particularly enriched in rhodium and the lesser PGEs osmium, iridium, and ruthenium. More importantly, the reported high-grade rhodium results correlate with specific chromite seams and correspond to geochemical and geophysical anomalies associated with our existing resource areas defined during 2021, highlighting our rapidly advancing understanding of their occurrence, and our ability to effectively target new areas."

President and CEO, Michael Rowley, stated, "Our 2022 programs built on the success of past campaigns, continuing to return rhodium at significant potential co-product values at a time when the U.S. is looking to increase domestic supplies of this very rare element, alongside 49 other critical minerals. We look forward to reporting our updated and expanded resource models in the near term as we advance Stillwater West towards its potential to become a primary low-carbon source of eight of the minerals listed as critical by the US government, effectively ushering in the next phase of critical mineral supply from the iconic and productive Stillwater Complex."

The Company is rapidly advancing the Stillwater West PGE-Ni-Cu-Co + Au project towards becoming a world-class source of low-carbon, sulphide-hosted nickel, copper, and cobalt, critical to the electrification movement, as well as key catalytic metals including platinum, palladium and rhodium used in catalytic converters, fuel cells, and the production of green hydrogen. Stillwater West positions SWCM as the second-largest landholder in the Stillwater Complex, with a 100%-owned position adjoining and adjacent to Sibanye-Stillwater's PGE mines in south-central Montana. The Stillwater Complex is recognized as one of the top regions in the world for PGE-Ni-Cu-Co mineralization, alongside the Bushveld Complex and Great Dyke in southern Africa, which are similar layered intrusions.

The J-M Reef, and other PGE-enriched sulphide horizons in the Stillwater Complex, share many similarities with the highly prolific complexes. SWCM's work in the lower Stillwater Complex has demonstrated the presence of large-scale disseminated and high-sulphide battery metals and PGE mineralization. Drill campaigns by the Company, complemented by a substantial historic drill database, have delineated five deposits of Platreef-style mineralization across a core 12-kilometer span of the project, all of which are open for expansion into adjacent targets. Multiple earlier-stage Platreef-style and reef-type targets are also being advanced across the remainder of the 32-kilometer length of the project based on strong correlations seen in soil and rock geochemistry, geophysical surveys, geologic mapping, and drilling.
