Sterling intercepts 203 m at 0.51% CuEq at MEPS; includes 16.25 m at 2.31% CuEq

TORONTO, ON / ACCESS Newswire / August 10, 2026 / Sterling Metals Corp. (TSXV:SAG)(OTCQB:SAGGF) ("Sterling" or the "Company") is pleased to report assay results from drill hole SC-26-13 at the MEPS Zone (" MEPS "), part of the Company's ongoing 20,000m drill program at the Soo Copper Project (" Soo Copper " or the " Project "), near Batchewana Bay, Ontario. Drilled approximately 140 metres east of SC-26-10 ( reported in a press release on July 29, 2026 ) the hole intersected 445.0m grading 0.40% copper equivalent (" CuEq ") (0.24% Cu, 172 ppm Mo, 0.05 g/t Au, 2.09 g/t Ag), including 203.10m grading 0.51% CuEq (0.38% Cu, 43.4 ppm Mo, 0.09 g/t Au, 2.99 g/t Ag) and higher-grade intervals of 16.25m grading 2.31% CuEq (1.90% Cu, 127.6 ppm Mo, 0.226 g/t Au, 12.09 g/t Ag) and 9.50m grading 2.34% CuEq (1.29% Cu, 63.6 ppm Mo, 0.88 g/t Au, 20.72 g/t Ag).

Highlights:

Strong near-surface mineralization of 203.10m grading 0.51% CuEq from 40.9m downhole within a longer interval of 445.0m of 0.40% CuEq starting from 22m depth.

Returned 9.50m grading 2.34% CuEq from 74m depth and 16.25m grading 2.31% CuEq from 176m depth associated with GFP porphyry sills.

The hole continued to intersect additional copper and molybdenum mineralization farther downhole in association with a strong quartz hydrothermal breccia with a copper interval intercepting 7.5m of 1.48% CuEq from 459m downhole.

Jeremy Niemi, P.Geo., Senior Vice President, Exploration and Evaluation, commented, "SC-26-13 is an outstanding result that combines nearly 450 metres of continuous mineralization with significant higher-grade copper intervals associated with GFP porphyry sills. The hole extends to the east, high grade copper mineralization intersected in hole SC-26-10 and strengthens our interpretation that this
