IP Geophysical Anomalies Expand To 12 Kilometers In Length At Stillwater West Critical Metals Project

VANCOUVER - Group Ten Metals Inc. reported results from the Induced Polarization geophysical (IP) survey completed in 2021 at its 100%-owned Stillwater West PGE-Ni-Cu-Co + Au project in Montana. The 2021 survey was completed as an expansion off the west end of the 2020 survey, covering the area between the Hybrid and DR deposits at Chrome Mountain and drill-defined high-grade gold mineralization at the Pine target area. The size and strength of the resulting geophysical signatures demonstrate additional potential for large bodies of sulphide mineralization.

Survey Highlights: 1) High-level geophysical anomalies, measured and modeled in 3D to 800 meters depth, extend the combined model from 9.2 kilometers ("km") to 12km in length in the center of the 32-kilometer-long Stillwater West project. 2) The five deposits defined by the Company's inaugural NI43-101 mineral resource estimate* are set in similar anomalies in the 2020 IP survey and show strong spatial correlations with IP results, demonstrating the effectiveness of the technique in targeting desirable Platreef-style sulphide mineralization in the lower Stillwater complex. 3) Results of the combined IP surveys suggest significant expansion potential for drill-defined sulphide mineralization in the 2021 mineral resource estimates which delineated a total of 1.1Blbs of nickel, copper, and cobalt, plus 2.4Moz of palladium, platinum, rhodium and gold. 4) The expanded survey included the Pine target area with the objective of finalizing drill targets and advancing drill-defined high-grade gold mineralization towards definition of a formal mineral resource. 5) Very high chargeability readings of over 180 mV/V were returned in the Pegmatoid Ridge target area, coincident with a strong kilometer-scale gold-in-soil anomaly that is contiguous with drill-defined high-grade gold at the Pine target, two kilometers to the southeast. Anomalous palladium, platinum, nickel and copper are also seen in soils in this area. 6) IP geophysics has proven to be an effective tool for identifying high-grade sulphide mineralization in the lower Stillwater Igneous Complex, guiding Group Ten's 2020 and 2021 drill campaigns to the discovery of multiple new high-grade magmatic horizons of Platreef-style nickel and copper sulphide mineralization, with palladium, platinum, rhodium, gold, and cobalt.

Michael Rowley, President and CEO, said, "Results from the 2021 IP geophysical survey expanded our model of the core project area by 30% in length and advanced very high-quality targets with some of the highest chargeability readings to date. 3D models developed from the combined survey - and the strong correlation with drill-defined mineralization that is demonstrated across the core 12-kilometer span of the project - highlight the remarkable scale and potential of the mineralized system at Stillwater West and provide important information on structure and geometry for our predictive geologic model to guide future drill campaigns. Near-term, we are looking forward to announcing additional assay results from the 14 resource expansion holes drilled in 2021. Those results will allow us to finalize our exploration plans for 2022 which will focus on resource expansion drilling in priority deposit areas in addition to other high priority targets within the now expanded 12km core project area."
