Sterling Metals expands Soo copper footprint

TORONTO, ON / ACCESS Newswire / June 17, 2026 / Sterling Metals Corp. (TSXV:SAG)(OTCQB:SAGGF) ("Sterling" or the "Company") is pleased to report assay results from the first six holes of it 2026 drilling program at the Soo Copper Project (" Soo Copper " or the " Project ") located near Batchewana Bay, Ontario. These results continue to demonstrate the scale and continuity of the Soo Copper system at the MEPS Discovery (" MEPS "), expanding the footprint of copper mineralization, confirming a copper bearing, multi-phase porphyry stock across a 1.4-kilometre corridor (Figure 1), and identifying a new higher grade molybdenum zone at depth. Highlights Broad intervals of near surface mineralization returned: 503.9m of 0.26% CuEq (0.14% Cu, 0.05 g/t Au, 0.64 g/t Ag, 177.4 ppm Mo) from 3.1m depth in SC-26-04; 289.5m of 0.26% CuEq (0.2% Cu, 0.03 g/t Au, 0.97 g/t Ag, 50.9 ppm Mo) from 3.5m depth in SC-26-05; and 214.5m of 0.29% CuEq (0.22% Cu, 0.02 g/t Au, 0.94 g/t Ag, 75.3 ppm Mo) from 3.0m depth in SC-26-06, including 10.5m of 1.01% CuEq (0.41% Cu, 0.07 g/t Au, 2.67 g/t Ag, 1003.8 ppm Mo) from 207.0m depth.

Extensive copper-molybdenum mineralization highlights the robust mineralization system associated with the underlying porphyry complex. The presence of a multi-phase porphyry stock was intersected in two separate locations - beneath MEPS (SC-26-04 and SC-26-05) and approximately 1km east of MEPS (SC-26-01 and SC-26-02) - supporting Sterling's interpretation of a robust copper system. The Company has drilled over 12,000m across 22 holes in 2026.
