Midland identifies copper anomalies at Lac Bernard

MONTREAL, June 11, 2026 (GLOBE NEWSWIRE) -- Midland Exploration Inc. ( “ Midland ” ) ( TSX-V: MD ) is pleased to announce the final results from its 2025 high-resolution lake bottom survey completed on the Lac Bernard project, in the Eeyou Istchee James Bay and Caniapiscau regions. The Lac Bernard project is wholly owned by Midland and consists of 271 exclusive exploration rights (“EER”) covering an area of 138 square kilometres, including 54 new EER recently added. Highlights: Results from the 2025 lake bottom sampling survey successfully identified eight (8) anomalies that returned more than 250 ppm Cu, with a maximum value of 533 ppm Cu; Three (3) clusters of lake bottom copper anomalies were identified on the project; Soil and prospecting exploration program to begin in June.

A high-density lake sediment survey was conducted on the Lac Bernard, Viau and in the southeastern part of the Caniapisc Au projects in 2025. The survey targeted areas where strong polymetallic (Cu, Mo, Zn, W) lake sediment anomalies were present in regional Quebec government survey. The 2025 survey successfully confirmed and replicated the original Quebec government data and anomalies.

The higher density survey further strengthened their significance and localization. On the Lac Bernard project, several strongly anomalous copper (Cu) lake sediment anomalies were identified in three (3) different areas. A total of eight (8) lake sediment samples returned more than 250 ppm Cu, with a maximum value of 533 ppm Cu (0.05% Cu), while seventeen (17) other samples returned between 130 and 250 ppm Cu.

In comparison, the regional median value for copper calculated from 1 161 regional lake bottom samples, including the Quebec government public data and the new results, is about 26 ppm Cu. Moreover, several anomalies in gold (Au) and molybdenum (Mo
