Sterling intercepts 44.1 m of 1.02% CuEq at MEPS copper zone

TORONTO, ON / ACCESS Newswire / October 5, 2026 / Sterling Metals Corp. (TSXV:SAG)(OTCQB:SAGGF) ("Sterling" or the "Company") is pleased to report assay results from drill holes SC-26-27 and SC-26-28 at the MEPS Zone (" MEPS "), part of the Company's ongoing drill program at the Soo Copper Project (" Soo Copper " or the " Project "), near Batchewana Bay, Ontario. SC-26-27 extends the continuous higher-grade mineralization across the MEPS Copper Zone 6 returning 44.1m of 1.02% CuEq within a near-surface longer interval of 187m grading 0.34% CuEq (Figure 2). Copper mineralization continues to expand with continued drilling.

Highlights:

SC-26-27 extended the near surface zone of continuous, higher-grade mineralization returning 44.1m grading 1.02% CuEq (0.96% Cu) including 18.2m of 2.02% CuEq (1.92% Cu) within a longer, near-surface interval of 187m grading 0.34% CuEq (0.32% Cu).

Intersected discrete zones of very copper-rich mineralization, including those developed in association with strong hydrothermal breccias, which are clearly characteristic of the MEPS system and occur across a broad continuous footprint of copper mineralization.

Sterling has now completed 53 holes totaling more than 22,000m in 2026, exceeding the Company's minimum 20,000m drill program. Given the cost advantages and lack of drill seasonality, drilling continues with no current plans to stop.

Jeremy Niemi, P.Geo., Senior Vice President, Exploration and Evaluation, commented, "SC-26-27 is another encouraging result from a system that continues to get larger as we drill it. The hole returned 44.1 metres grading 1.02% CuEq (0.96% Cu), including 18.2 metres grading 2.02% CuEq (1.92% Cu), extending the continuous, higher-grade core zone of MEPS to the west within a broad, coherent envelope of copper mineralization.
