MONTREAL, Sept. 22, 2026 /CourierPR/ -- Midland Exploration Inc., in partnership with SOQUEM Inc., has announced the results of its 2026 exploration campaign on the Nachicapau project, which follows the discovery of copper, gold, and silver occurrences along a 4-km-long by 1.5-km-wide corridor between 2022 and 2025. These new results are part of the Strategic Alliance between Midland and SOQUEM in the Labrador Trough in Nunavik, Quebec.
The 2026 exploration campaign, conducted over a period of 5 days in June, yielded a total of 54 rock samples. The results reveal that ten (10) grab samples show grades equal to or greater than 0.10% copper (Cu), including four (4) samples above 1.00% Cu, reaching up to 26.8% Cu. Anomalous gold values above 0.1 g/t Au are associated with these samples, while three (3) samples exhibit silver values reaching up to 238 g/t Ag. These results highlight a close relationship between copper (Cu), gold (Au), and silver (Ag) mineralization and the presence of monzonite dykes, alkalic ultramafic units, and regional structural features.
The best results of the June 2026 campaign were obtained in grab samples collected in boulders, consisting of calcite-dolomite-quartz veins crosscutting a monzonite. The mineralization is characterized by the presence of centimetre-scale patches of digenite and malachite within the veins and in their selvages. Hematite is a common accessory mineral and occurs as distinctive specularite crystals. The host rock is weakly deformed and systematically altered to albite, epidote, and hematite.
On outcrop, these dykes crosscut, at low angles, alkalic mafic to ultramafic volcanic units of the Murdoch Formation. Copper mineralization occurs in calcite-dolomite-quartz tension gashes. Sample C2130669, which graded 0.59% Cu, 0.77 g/t Au, 10.3 g/t Ag, confirms the extension of both the mineralized zone and the monzonite dyke north of the DG-12 showing discovered in 2025 (1.46% Cu, 0.14 g/t Au, 9.20 g/t Ag in a monzonite dyke). Samples C2130681 to C2130685, collected on either side of the DG-5 showing (2.95% Cu, 0.01 g/t Au, 27.6 g/t Ag), extend the mineralized zones associated with monzonite dykes over a distance of 150 metres. Sample C2130684, collected in a digenite-malachite vein, yielded showing-level grades of 3.03% Cu, 0.17 g/t Au, and 20.0 g/t Ag.
Mineralization associated with mafic to ultramafic volcanic units was also observed. Three (3) samples collected in ultramafic schist and intrusive units yielded anomalous Cu, Au, and Ag values. Sample C2130651, which did not appear to be mineralized, yielded values of 0.10% Cu, 0.13 g/t Au, and 0.76 g/t Ag, i.e., respectively 30 to 100 times higher than regional background values. This observation suggests that copper mineralization is not exclusively found in veins but may also occur disseminated within deformed and altered ultramafic units.
The 2025 OreVision® induced polarization survey helped improve understanding of the geological setting and Cu-Au-Ag mineral occurrences on the Nachicapau project. Sedimentary units (dolomite, mudstone), mafic intrusives, and ultramafic schists can be distinguished based on resistivity and chargeability contrasts. Copper mineralization is closely linked with low-resistivity (<6,000 Ohm.m) and moderate chargeability (7-14 mV/V) zones within the ultramafic schist unit and along the contact with sedimentary units.
Cu-Au-Ag mineralization on the Nachicapau project appears to be related to deformed and altered mafic to ultramafic volcanic units of the Murdoch Formation, where it occurs as disseminated digenite and malachite, monzonite dykes where it occurs in veins with higher-grade Cu, Au, Ag, and intense albite-epidote-hematite alteration occurring around the veins. Low-resistivity copper mineralization (<6,000 Ohm.m) and moderate-chargeability (7-14 mV/V) zones are also observed. A deformation corridor trending N350 that affects volcanic units and a major shear zone marking the contact with sedimentary units are also identified.
The 2026 exploration campaign was designed to follow up on chargeability and conductivity anomalies outlined by the Orevision® induced polarization survey conducted in 2025. The campaign was conducted over a period of 5 days in June, during which a total of 54 rock samples were collected.
