CORRECTION FROM SOURCE: Group Ten Reports 13.2 m of 3.33% Nickel Equivalent Within 401 m Continuous Mineralization from Resource Expansion Drilling

Results continue to support the Company's priority objective of expanding the October 2021 inaugural mineral resource estimates with multiple wide and highly mineralized intervals returned in step-out drilling in the DR-Hybrid deposit area at Chrome Mountain (see Table 1 and Figure 1). Drilling in 2021 focused on resource expansion in three of the five deposit areas delineated by the 2021 estimates. Similar wide and well-mineralized intervals have now been reported from all three deposit areas as announced December 20, 2021, and March 7, 2022. Mineralization remains open to expansion along trend and at depth in all five deposit areas, that are in the 12-kilometer-long resource area within the broader 32-kilometer-long land package in the lower Stillwater Igneous Complex (see Figure 2).

Highlights:

• CM2021-05 returned 400.8 meters of continuous battery and precious metal mineralization grading 0.30% Nickel Equivalent ("NiEq"), equal to 0.80 g/t Palladium Equivalent ("PdEq"), with successive contained higher-grade intervals including 96 meters of 0.60% NiEq (1.56 g/t PdEq) and including 13.2 meters of 3.33% NiEq (8.88 g/t PdEq) as 2.31% Ni, 1.51 g/t Pd+Pt+Au+Rh ("4E"), 0.35% Cu and 0.115% Co starting at 37.6 meters. This is one of the widest high-grade intercepts ever recorded in the Stillwater district.
• The results from CM2021-05 represent an important new discovery with the same distinctive signature of high-grade nickel sulphide, platinum group metals and gold as encountered in CM2020-04, which returned 8.5 meters of 1.74% NiEq (or 4.65 g/t PdEq) within a broad mineralized package located approximately 125 meters to the west. This zone remains open to further expansion with additional drilling.
• CM2021-06 returned 0.26% NiEq (0.71 g/t PdEq) over 345.0 meters, including 75.4 meters of 0.37% NiEq, or 0.99 g/t PdEq, and a second, lower interval with 148.4 meters of 0.30% NiEq, or 0.79 g/t PdEq.
• CM2021-04 returned 247.2 meters of 0.21% NiEq (0.57 g/t PdEq) mineralization including two long intervals at higher grades.
• Results also continue to highlight the potential for significant co-product rhodium values at Stillwater West, with drill samples in Chrome Mountain holes CM2021-04, -05, and -06 up to 0.36 g/t Rh within the mineralized horizons. At recent values, rhodium trades at more than 16 times the value of platinum and 8 times the value of palladium on a spot price basis at over USD 16,000 per ounce. Sibanye-Stillwater, adjacent to Group Ten's Stillwater West project, is the primary US producer. Supply constraints for rhodium have supported rising prices since 2017.
• Assay results remain pending from five holes in the HGR deposit area at Iron Mountain and portions of holes CZ2021-01 and IM2021-04, in addition to rhodium assay results on a number of mineralized intervals reported to date.

These results, in addition to results released March 7, 2022 and December 20, 2021, demonstrate significant potential to expand the October 2021 mineral resource estimates with multiple long intervals at grades well above the 0.20% NiEq cut-off grade used in that study (see bolded assay values on Table 1). Potential is also shown to expand existing resources at higher cut-off grades, such as 0.35% and 0.50% NiEq (red values and shaded rows, respectively, on Table 1). Moreover, as shown in Figures 1 to 4, these results provide important intercepts in step-out drill holes located up to several hundred meters from the resource estimate block models.

Dr. Danie Grobler, Group Ten's Vice-President of Exploration, commented "I am excited to extend my experience obtained over the past two decades at the Platreef in the northern Bushveld Complex to Group Ten's Stillwater West project. We see significant comparability with Platreef-style mineralization in the lower Stillwater Complex and in particular, early evidence of higher-grade Flatreef pegmatoidal-style mineralization targets within the project's layered magmatic stratigraphy."

Michael Rowley, President and CEO, commented, "The high-grade intercept in hole CM2021-05 is the latest in a series of exciting discoveries made by our team in the lower Stillwater complex through the development of a new predictive geologic model for this famously metal-rich district. This notable intercept demonstrates the same high tenor nickel sulphide mineralization as a similar interval in CM2020-04, 125 meters away, and is in an area that is completely outside of the current resource block model. It also represents one of the widest high-grade battery and precious metal intercepts to date in the Stillwater district. Further step-outs on this new target, situated between the existing DR and Hybrid deposit areas, are a priority for the coming season. Overall, we continue to see confirmation of a large mineralized system with an impressive endowment of eight of the commodities listed as critical by the US government. We look forward to reporting additional remaining drill results from the 2021 Iron Mountain drilling, exploration plans for 2022, and other news in the near term."

Table 1 - Highlight Results from the 2021 Expansion Drill Campaign at the DR and Hybrid Deposit Areas

Highlighted significant mineralized intercepts are presented above. Grade-thickness values cover significant mineralized intervals with total palladium and nickel equivalent grade-thickness determined by multiplying the thickness of continuous mineralization (in meters) by the palladium equivalent grade (in grams/tonne) to provide gram-meter values (g-m) or by multiplying the nickel equivalent grade (in percent) to provide percent-meter values as shown. Total nickel and palladium equivalent calculations reflect total gross metal content using long term metal prices (all USD): $7.00/lb nickel (Ni), $3.50/lb copper (Cu), $20.00/lb cobalt (Co), $1,000/oz platinum (Pt), $1,800/oz palladium (Pd), and $1,600/oz gold (Au). Equivalent values have not been adjusted to reflect metallurgical recoveries. Total metal equivalent values include both base and precious metals. Intervals are reported as drilled widths and are believed to be representative of the actual width of mineralization.

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 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 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.

Quality Control and Quality Assurance

2021 drill core samples were analyzed by ACT Labs in Vancouver, B.C. Sample preparation: crush (< 7 kg) up to 80% passing 2 mm, riffle split (250 g) and pulverize (mild steel) to 95% passing 105 µm included cleaner sand. Gold, platinum, and palladium were analyzed by fire assay (1C-OES) with ICP finish. Selected major and trace elements were analyzed by peroxide fusion with 8-Peroxide ICP-OES finish to insure complete dissolution of resistate minerals. Following industry QA/QC standards, blanks, duplicate samples, and certified standards were also assayed.
