(TSXV:SAG)(OTCQB:SAGGF) (\"Sterling\" or the \"Company\") is pleased to announce the discovery of a high-grade copper zone at its Soo Copper Project (\"Soo Copper\" or the \"Project\") located in Batchewana Bay, Ontario. Drill hole MEPS-25-02, part of the Company's Phase 2 exploration program, discovered a high-grade copper and gold zone within a continuous, bulk-tonnage copper-molybdenum-silver-gold porphyry system (Figure 5).HighlightsDiscovery hole intersects 262.5m of 1.05% CuEq starting from 47.5m downhole, including a new high-grade bornite zone with 68.3m grading 3.25% CuEq starting at 179.7m downhole, featuring semi-massive bornite and chalcopyrite grading up to 9.3m of 19.98% CuEq (see Table 1 for full results and Figure 6).Highest copper and gold grades encountered to date at Soo Copper, including:33% Cu over 0.55m starting at 220.45m depth; and196 g/t Au and 21.3% Cu over 0.6m starting at 219.85m depth.Newly discovered high-grade Cu-Au mineralization, characterized by bornite and associated porphyry dykes, indicates a robust, large-scale Cu-Au-Ag-Mo system with the potential to transform the Project.Phase 2 drilling has been expanded from a minimum of 3,000m to at least 6,000m.A core photo gallery is now available on Sterling's website, click here to view.The Company will be hosting a live webinar to discuss the results on Wednesday, October 1, 2025, at 11:00 am eastern.

The first hole drilled at MEPS provided critical geological context, refining the interpretation of the mineralized trend and guiding adjustments to subsequent drill angles.Building on this foundation, MEPS-25-02 was designed to test a more favourable portion of the target. The hole revealed bornite within the first 25m and intersected c...
