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) were also identified in many of these lake bottom samples. On the Viau project, several Zn, Mo and Au anomalies were also identified. These anomalies all remain unexplained. On the Lac Bernard project, a 326-soil sampling program and a week of prospecting is planned to begin in June to follow up on these anomalies. Prospecting will also occur on the Viau project.

Lac Bernard and Viau Projects

The Lac Bernard project is located 30 kilometres south of Caniapisc Au and covers several Au, Cu, Mo, and Zn lake bottom anomalies, from the MRNF database, that are located in an area showing a favourable magnetic complexity, as observed on the available federal magnetic data covering the region. The Viau project is located 16 kilometres west of Caniapisc Au and covers several Zn and Mo lake bottom anomalies, from the MRNF databases, located on a magnetic high that could represent the signature of a fluorite granite identified by the MRNF in the same area.

Quality Control

The design, processing and interpretation of the lake sediments survey was performed by qualified persons employing a Quality Assurance/Quality Control program consistent with industry best practices, including the use of standards and blanks. Lake sediment samples were collected and preprocessed by IOS Services Geoscientifiques at Saguenay, Quebec. Lake sediment samples were shipped and analyzed at Activation Laboratories at Ancaster, Ontario, by 2 different methods: 1) instrumental neutron activation analysis (INAA); 2) inductively coupled plasma atomic emission spectroscopy (ICP-AES) after an aqua-regia digestion.

Cautionary statements

Lake bottom sample anomalies are from the secondary environment, and anomalies are not necessarily indicative of mineralized zones.

Mineralization occurring at deposits and former mines mentioned in this press release is not necessarily indicative of mineralization that may be intersected on projects held by Midland described in this press release.
