VANCOUVER, British Columbia, July 15, 2025 (GLOBE NEWSWIRE) -- Callinex Mines Inc. (the “Company” or “Callinex”) (TSX-V: CNX; OTCQX: CLLXF) is pleased to announce that it has received approval for a grant of up to $150,000 from the Newfoundland and Labrador Junior Exploration Assistance (JEA) Program for its 100% owned Point Leamington Project (the “Project”). Additionally, the Company has secured additional exploration permits from the Department of Natural Resources, Newfoundland and Labrador, for the Project, which encompasses the Pt. Leamington volcanogenic massive sulphide (“VMS”) Deposit, located on the island of Newfoundland, hosting a significant resource of gold, copper, zinc, and silver. The permits were approved just two weeks after submission, demonstrating the province’s streamlined approach and reputation as a mining-friendly jurisdiction.

Max Porterfield, President & CEO of Callinex Mines, stated, “We are thrilled to receive this significant financial support from the Newfoundland and Labrador JEA Program, alongside the rapid approval of additional exploration permits. The swift permitting process, with approvals granted just two weeks after submission, underscores Newfoundland’s reputation as a tier-one mining jurisdiction. This grant and the expanded permits position us to aggressively advance the Pt. Leamington Project, expanding the resource base and unlocking the critical mineral potential of this exciting project.”

The JEA grant, administered by the Department of Industry, Energy and Technology, Newfoundland and Labrador, supports the Company’s 2025 exploration plans targeting critical minerals as the primary exploration focus. The funding will contribute to exploration work aimed at expanding the Pt. Leamington Deposit and refining and testing exploration targets along strike. The additional permits expand the scope of approved activities to include prospecting, geologic mapping, and geochemical rock sampling within prospective areas of the broader land package, further advancing exploration efforts.

The Point Leamington Project, consisting of a mining lease and exploration claims, is located approximately 37km by road and trails from the City of Grand Falls-Windsor and approximately 20km from the provincial power grid. The Deposit is a large, felsic-hosted VMS deposit with a pit-constrained Indicated Mineral Resource of 5.0 Mt grading 2.5 g/t AuEq for 402 koz AuEq (145.7 koz gold, 60.0 Mlb copper, 153.5 Mlb zinc, 2.0 Moz silver, 1.5 Mlb lead), a pit-constrained Inferred Mineral Resource of 13.7 Mt grading 2.24 g/t AuEq for 986.5 koz AuEq (354.8 koz gold, 110.2 Mlb copper, 527.3 Mlb zinc, 6.2 Moz silver, 7.0 Mlb lead), and an out-of-pit Inferred Mineral Resource of 1.7 Mt grading 3.06 g/t AuEq for 168.5 koz AuEq (65.4 koz gold, 13.3 Mlb copper, 102.9 Mlb zinc, 1.4 Moz Ag, 2.6 Mlb lead) ().

The planned exploration campaign will leverage the recently secured two-year exploration permit (valid through June 2027) for ground geophysics and diamond drilling, as well as the newly approved permits for surface field exploration. These additional permits enable prospecting, geologic mapping, and geochemical sampling to refine high-priority targets identified from airborne electromagnetic anomalies along strike from the Deposit.

The JEA Program’s financial support and the Department of Natural Resources’ efficient permitting process highlight Newfoundland and Labrador’s commitment to fostering exploration and development of critical mineral resources.
