[{"type":"text","content":"Sterling Metals Discovers Cu-Mo Porphyry Stock 1.5km from MEPS Discovery Zone Confirming Scale of Porphyry Copper SystemTORONTO, ON / ACCESS Newswire / March 1, 2026 / Sterling Metals Corp. (TSXV:SAG)(OTCQB:SAGGF) (\"Sterling\" or the \"Company\") is pleased to report that in the first drill hole of the 2026 drill program, the Company has discovered a greater than 400m zone of felsic porphyry stock hosting widespread, multi-stage copper and molybdenum sulphide mineralization with potassic alteration and porphyry-type veining.The blind porphyry stock was drill-intersected approximately 1.5km from the MEPS Discovery (\"MEPS Discovery\") that is highlighted by a 400 x 400m continuous zone of near-surface copper mineralization centered around discovery hole MEPS-25-02 that contained 265.5m of 1.05% CuEq* including 68.3m of 3.25% CuEq*(see press release dated September 29, 2025). The presence of a Cu-Mo mineralized felsic porphyry stock so far from the MEPS Discovery provides further strong evidence for the presence of a giant porphyry copper system at the Soo Copper Project, located off the Trans-Canada Highway only 70km north of Sault Ste Marie and 20 km from rail and deep-water access.HighlightsDrillhole SC-26-01 was designed to test a ZTEM resistivity low geophysical target in proximity to bornite and chalcopyrite exposures in outcrop and as a large step-out to the MEPS Discovery (Figure 1 and 2).At approximately 530m vertical depth, a thick zone of altered mafic volcanics transitioned sharply into a coarse-grained felsic porphyry, interpreted as part of a stock-like intrusive body, which was then drilled for over 400m currently continuing at approximately 1000m depth. The porphyry stock contains widespread, overall weak to moderate, but locally strong development of copper sulphides as fine chalcopyrite and bornite disseminations in the groundmass and as coarser grains within veins and is closely associated with potassic feldspar alteration. Molybdenite is also commonly present within quartz veins with or without chalcopyrite (see Figure 3, 4 and 5).While assays are not expected for some time, the evidence from this hole suggests this is not the core of the mineralized stock but a peripheral part of a larger copper zone. However, it does confirm that there is a large porphyry stock complex associated with the surface copper show...
