Brixton Metals Corporation has initiated a dedicated sonic-drilling campaign to define a potential initial Mineral Resource Estimate (MRE) from historic tailings at its wholly owned Langis Silver Project in the Cobalt silver mining camp of Ontario, Canada. The company announced that three rigs are now active, with the tailings program targeting a compliant resource to advance a Recovery and Remediation Plan and generate near-term cash flow. Two additional rigs are executing the fully funded 60,000-meter 2026 bedrock drill program to expand known mineralized zones and test unmined extensions.
2026 Objectives at the Langis Silver Project
- Define a maiden tailings Mineral Resource Estimate 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.”
Tailings Evaluation and 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 aims to delineate a potential MRE, advance a Recovery and Remediation Plan, and generate near-term cash flow. Beyond 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. The framework is intended to support faster mineral recovery activities while maintaining health, safety, and environmental protections.
The opportunity is underpinned by historical processing records indicating that the tailings were milled at an average feed grade of approximately 20 to 25 opt silver, with recoveries of about 88%. This implies that roughly 2.4 to 3.0 opt (approximately 75 to 95 g/t) of silver, representing the unrecovered balance, may remain in the legacy tailings, and this residual silver is the focus of the company’s tailings drilling and metallurgical test work. These historical figures are unverified and conceptual in nature.
