Sterling drills 57 m of 0.81% CuEq below MEPS discovery

TORONTO, ON / ACCESS Newswire / July 29, 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. All three holes were drilled from the same pad at the MEPS Zone (" MEPS "). Highlights: Discovery of a molybdenite-rich breccia body immediately below the high-grade copper zone demonstrates potential for molybdenum to become an economically material co-product to copper, representing a second critical metal to the Soo Project while also adding over 100 m of vertical depth to the MEPS Discovery zone highlighted by 57 m of 0.81% CuEq (0.21% Cu, 1077 ppm Mo, 0.04g/t Au, 1.17g/t Ag) Near-vertical drill hole demonstrates continuous extent of copper-dominant mineralization from bedrock surface at 4.0m depth down to greater than 400 m depths with a key interval of 358 m grading 0.5% CuEq (0.32% Cu, 237ppm Mo, 0.04 g/t Au, 2.21g/t Ag) from 50 m depth Upper and Lower GFP Copper Zones continue to demonstrate continuity and high grades in the core of the MEPS Discovery highlighted by the Lower GFP Copper Zone intercept of 8.5 m grading 4.73% CuEq (3.98% Cu, 0.43 g/t Au, 28.99g/t Ag, 118 ppm Mo) Hole SC-26-10 was drilled to provide a near-vertical, continuous section of the high-grade copper discovery zone and to explore for the first time the zone immediately below the high-grade copper zone, that nearby, previously completed drillholes indicated the possible presence of a molybdenum-copper ("Mo-Cu") breccia body; see Figures 1 and 2.

Starting from just 4.0 m downhole SC-26-10 intersected 497.6 m grading 0.41% copper equivalent (" CuEq ") (0.24% Cu, 227.7 ppm Mo, 0.03 g/t
