Brixton Metals commences maiden tailings resource drilling at Langis Silver

Three Rigs Now Active to Advance the 60,000-Meter Exploration Campaign and Tailings Mineral Resource Estimate VANCOUVER, British Columbia, June 18, 2026 (GLOBE NEWSWIRE) -- Brixton Metals Corporation (TSX-V: BBB, OTCQX: BBBXF) (the “ Company ” or “ Brixton ”) is pleased to report that it has commenced a dedicated sonic-drilling campaign to define a potential initial Mineral Resource Estimate (MRE) from the historic tailings at its wholly owned Langis Silver Project, located in the Cobalt silver mining camp of Ontario, Canada (Figure 1). The tailings program targets a potential compliant resource to advance a Recovery and Remediation Plan and generate near-term cash flow, while two additional rigs execute the Company’s fully funded 60,000-meter 2026 bedrock drill program to expand known mineralized zones and test unmined extensions, bringing the total to three rigs now active across the Project. Highlights 2026 objectives at the Langis Silver Project: Define a maiden tailings Mineral Resource Estimate (MRE) through dedicated sonic drilling.

Test new structural and unconformity targets for additional mineralization. Extend and infill known high-grade silver zones to improve continuity. Gary R. Thompson, Chairman and CEO, stated: “ Commencing dedicated drilling on the Langis tailings is an important step toward defining a maiden resource with the objective of generating near-term cash flow.

With the surface rights and patented claims already in hand and Ontario’s new recovery framework in place, we are well positioned to advance this opportunity, while our two bedrock rigs continue to expand the high-grade silver potential across the broader property .” Figure 1.

Tailings Evaluation & Resource Delineation Campaign An active sonic drill rig on-site is entirely dedicated to evaluating the historic tailings areas from operations spanning 1956 through 1968.

The Company’s objective is to delineate a potential Mineral Resource Estimate (MRE), advance a Recovery and Remediation Plan, and generate near-term cash flow. In addition to its economic potential, the project represents a meaningful environmental remediation opportunity by recovering valuable metals from historic mine waste while reducing the long-term environmental footprint of the legacy tailings facility. Successfully defining a compliant resource could also provide non-dilutive funding to sustain and expand long-term, hard-rock exploration drilling across the broader Langis property.

This initiative aligns with the Government of Ontario’s new regulatory framework for the recovery of residual minerals from tailings and other mine wastes. Effective July 1, 2025, Ontario’s Recovery of Minerals regime under the Mining Act establishes a streamlined permitting process that allows qualifying projects to proceed with a recovery permit rather than a full closure plan. Applicants must submit a Recovery and Remediation Plan and satisfy applicable consent, consultation, financial assurance and regulatory requirements.
