Highest Grade And Widest Mineralized Intercepts To Date At Stillwater West Battery Metals & PGE Project

VANCOUVER - Group Ten Metals Inc. reported partial results from the first two drill holes of the 14-hole resource expansion campaign completed in 2021 at the Company's flagship Stillwater West PGE-Ni-Cu-Co + Au project in Montana, USA. Results are expected to form the basis of an updated resource estimate in 2022.

2021 Drill Highlights: CZ2021-01 returned the widest high-grade intercept to date on the project being 63.7 meters of 0.92% Nickel Equivalent ("NiEq"), equal to 2.46 g/t Palladium Equivalent ("PdEq"), with 0.47% Ni, 0.42 g/t Pd, 0.27% Cu, and 0.04% Co as well as significant Pt and Au values, within 367.6 meters of continuous mineralization at 0.31% NiEq (or 0.83 g/t PdEq); and CM2021-01 returned the longest mineralized intercept ever recorded in the Stillwater district with 728 meters of continuous sulphide mineralization at 0.27% NiEq, or 0.73 g/t PdEq, including contained intervals of successively higher grades: 352.9 meters of 0.39% NiEq (or 1.04 g/t PdEq) with 0.52 g/t 3E (Pd, Pt, and Au), and 0.17% Ni, plus significant Cu and Co values; 159.2 meters of 0.48% NiEq (or 1.29 g/t PdEq) with 0.77 g/t 3E, 0.18% Ni, plus significant Cu and Co values; 50.2 meters of 0.54% NiEq (or 1.45 g/t PdEq) with 1.0 g/t 3E, 0.19% Ni, plus significant Cu and Co values; and Shorter intervals of high-grade mineralization including 7.2 meters of 1.33 g/t Pd, 0.93 g/t Pt, and 0.24% Ni, plus significant Au, Cu, and Co values, for 1.02% NiEq (or 2.72 g/t PdEq).

Both holes are step-outs completed with the objective of expanding deposits delineated by the 2021 Mineral Resource Estimate announced on October 21, 2021: CM2021-01 was one of six holes drilled in 2021 in the area between the DR and Hybrid deposits to step out from high-grade nickel sulphide-PGE mineralization identified in hole CM2020-04; and CZ2021-01 is one of two holes drilled in 2021 to step-out on the CZ deposit in the area of wide, high-grade mineralization returned in hole CZ2019-01.

The Mineralization starts at or near surface in both holes, and assay results are pending from the lowest portion of CZ2021-01, and from the remaining 12 holes drilled in 2021. Rhodium results are also pending on all holes.

Michael Rowley, President and CEO, said, "These initial results from the first two holes of our 2021 resource expansion drill campaign provide the strongest demonstration to date of our ability to target highly mineralized zones at Stillwater West, with significant wide intervals reaching more than five times the cut-off grade used in our recent resource estimate. This is very clear evidence that our predictive geologic model, utilizing tools like deep penetrating induced polarization geophysics, is accurately and effectively guiding us to drill wide zones of higher-grade nickel-copper-cobalt sulphide mineralization (battery metals), enriched in palladium, platinum, rhodium (platinum group elements), and gold. In addition to driving increased size and grade in our planned resource update, our ability to target effectively as we step-out from known mineralization in a large magmatic system is delivering incredibly low discovery costs as we advance the project.

"Our work to date has demonstrated the exceptional scale and potential of the mineralized system in the lower Stillwater Complex. These results confirm and refine that understanding with Chrome Mountain hole CM2021-01 returning nearly three-quarters of a kilometer of continuous mineralization from a site that is over seven kilometers west of the HGR deposit in the Iron Mountain area, where hole IM2019-03 previously held the record for highest grade-thickness. Both areas have additional very high grade-thickness intervals in drill results, as does the CZ deposit located between the two. All of this confirms our observation that the lower Stillwater Complex has an immense endowment of contained metal and yet is surprisingly underexplored, despite its location in a famously productive and well-mineralized American mining district. Our systematic approach to exploration has quickly delineated five resource-stage deposits that are open for expansion across the nine-kilometer core of the Stillwater West project and we will continue to focus on their expansion while also advancing earlier stage targets that continue across the 32 kilometers of prospective magmatic stratigraphy covered by the property. We look forward to announcing results from the remaining drill holes along with results of our 2021 IP expansion survey in the near term as they become available."
