Group Ten Metals Announces Name Change to Stillwater Critical Minerals

VANCOUVER, June 9, 2022 - Group Ten Metals Inc. (TSX.V:PGE; OTCQB:PGEZF; FSE:5D32) (the "Company" or "Group Ten") is pleased to announce that, effective at market opening on June 13, 2022, the common shares of the Company will trade on the TSX Venture Exchange under the name "Stillwater Critical Minerals Corp." to better reflect the commodity suite of battery, catalytic and precious metals at the Company's flagship Stillwater West project in Montana, USA. The project hosts a total of eight metals (nickel, cobalt, chromium, palladium, platinum, rhodium, iridium and ruthenium) designated as critical by the United States government with a mandate to secure domestic supplies based on economic and national security concerns. Stillwater West also hosts significant copper resources.

President and CEO Michael Rowley commented "Rebranding Group Ten Metals to Stillwater Critical Minerals reflects our increasing focus on our flagship project and the great potential we see in the iconic and famously productive Stillwater mining district. With the recent addition of two renowned Bushveld and Platreef geologists to our team we are well positioned to advance the next phase of large-scale critical mineral supply from the district, building on past production of nickel, copper, and chromium, and the on-going production of platinum group and other metals by our neighbor, Sibanye-Stillwater. Our Platreef-style nickel and copper sulphide deposits contain a compelling suite of critical minerals and are open for expansion along trend and at depth. We look forward to further announcements including assay results from our 2021 resource expansion drill campaign and our 2022 exploration plans in the near term."

The Company's stock symbols remain the same (TSX.V: PGE | OTCQB: PGEZF | FSE:5D32). The new CUSIP number is 86074L103 and the new ISIN number is CA86074L1031. In addition, the Company is pleased to announce the launch of a new website, www.criticalminerals.com, and new Twitter handle, @Stillwater_CM.

About Stillwater West

Group Ten 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 for batteries and the electrification movement, as well as key catalytic metals including platinum, palladium, rhodium, iridium and ruthenium used in catalytic converters, fuel cells, and the production of green hydrogen. Stillwater West positions Group Ten 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, USA¹. 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 Merensky and UG2 Reefs in the Bushveld Complex. Group Ten's work in the lower Stillwater Complex has demonstrated the presence of large-scale disseminated and high-sulphide battery metals and PGE mineralization, similar to the Platreef in the Bushveld Complex².

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.

All statements in this release, other than statements of historical facts including, without limitation, statements regarding potential mineralization, historic production, estimation of mineral resources, the realization of mineral resource estimates, interpretation of prior exploration and potential exploration results, the timing and success of exploration activities generally, the timing and results of future resource estimates, permitting time lines, metal prices and currency exchange rates, availability of capital, government regulation of exploration operations, environmental risks, reclamation, title, and future plans and objectives of the company are forward-looking statements that involve various risks and uncertainties. Although Group Ten believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Forward-looking statements are based on a number of material factors and assumptions. Factors that could cause actual results to differ materially from those in forward-looking statements include failure to obtain necessary approvals, unsuccessful exploration results, changes in project parameters as plans continue to be refined, results of future resource estimates, future metal prices, availability of capital and financing on acceptable terms, general economic, market or business conditions, risks associated with regulatory changes, defects in title, availability of personnel, materials and equipment on a timely basis, accidents or equipment breakdowns, uninsured risks, delays in receiving government approvals, unanticipated environmental impacts on operations and costs to remedy same, and other exploration or other risks detailed herein and from time to time in the filings made by the companies with securities regulators.
