Sterling Metals intersects continuous copper mineralization from surface

TORONTO, ON / ACCESS Newswire / July 13, 2026 / Sterling Metals Corp. (TSXV:SAG)(OTCQB:SAGGF) ("Sterling" or the "Company") is pleased to report assay results from three additional drill holes completed as part of its ongoing 2026 drilling program at the Soo Copper Project (" Soo Copper " or the " Project "), located near Batchewana Bay, Ontario. Each hole intersected broad intervals of continuous copper mineralization beginning near surface, further defining the scale of the MEPS Zone (" MEPS ") and reinforcing Sterling's interpretation of a large, copper-dominant system with significant expansion potential. Holes SC-26-07, SC-26-08 and SC-26-09 tested the northwest and west extents of MEPS, intersecting 248.0 m to 323.0 m grading 0.30% to 0.34% CuEq (Copper Equivalent).

The results also refine the Company's understanding of the structural controls on mineralization, providing important information to guide future drilling (Figures 1 and 2). Highlights: Three additional near-surface copper intersections of up to 325 m averaging greater than 0.3% CuEq continue to define the scale, continuity and shallow nature of the MEPS Zone. Drilling continues to support Sterling's interpretation of a large copper system with widespread mineralization.

Higher-grade copper zones appear to be associated with favourable host rocks, providing a clear framework for targeting additional high-grade mineralization. Strong correlation between copper mineralization and IP chargeability anomalies continue to validate Sterling's exploration model and highlight significant potential to expand the footprint of MEPS. Jeremy Niemi, P.Geo., Senior Vice President, Exploration and Evaluation, commented, "These results reflect the methodical exploration approach we are taking at Soo Copper.

SC-26-07, SC-26-08 and SC-26-09 each intersected thick mineralized intervals within the first few metres of bedrock, extending
