Sterling Extends Core MEPS Copper Zone to 700m; Intersects 200m of 0.53% CuEq Including 102m of 0.81% CuEq

Sterling Metals Corp. announced new drill results from step-out drilling at its Soo Copper Project in Ontario, extending the MEPS porphyry copper zone to 700m. Hole SC-26-26 intersected 397.19m grading 0.37% CuEq, including 200m of 0.53% CuEq and a high-grade section of 13.25m at 1.82% CuEq. The results demonstrate significant scale and continuity of the copper mineralization, with detailed QA/QC procedures and transparent metal equivalent calculations.

Errington Metals Expands Depth Potential at the Errington Zone

Errington Metals Corp. announced initial results from its 2026 Spring exploration program at the Errington Zone, confirming multiple high-grade copper-zinc-lead-gold-silver intercepts at depth. The drilling extends mineralization and supports a new geological model suggesting the zone remains open for further growth. Elevated gold and silver values in the eastern part of the zone are expected to enhance overall value per tonne.

Sterling Increases Strike of MEPS Discovery to 1.3km and Discovers Molybdenum-Copper Porphyry Stock at Depth

Sterling Metals Corp. announced drill results from four holes at its Soo Copper Project in Ontario, extending the MEPS Zone discovery to over 1.3 km of strike. Hole SC-26-16 intersected a mineralized granite porphyry stock at its shallowest depth to date, confirming elevated molybdenum and associated copper. Highlights include 12 metres at 1.70% CuEq within a broader 101-metre interval grading 0.50% CuEq, indicating significant potential for expansion to the east and at depth.

Errington Metals Expands Depth Potential at the Errington Zone

Errington Metals announced initial 2026 drill results from its Errington Zone, confirming multiple high-grade polymetallic intercepts including 11.0 meters grading 6.41% CuEq in hole EME-26-086. The drilling extends mineralization at depth, with the zone remaining open for further growth, supported by a new geological model suggesting faulting and offset rather than termination. Elevated gold and silver values in the eastern part of the zone are noted to enhance overall value.

Mink Ventures Corporation Exploration Update

Mink Ventures reported results from its 2026 phase 2 drill program at the Warren Property, where drilling successfully intersected sulphide mineralization at predicted VTEM targets. However, most holes returned no significant nickel, copper, or cobalt, though hole W2620 returned an anomalous 0.2% Cu over 0.5m.
