BRIXTON METALS COMMENCES DRILLING FOR MAIDEN TAILINGS MINERAL RESOURCE ESTIMATE AT THE LANGIS SILVER PROJECT

Brixton Metals Corp. 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. 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-metre 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 chief executive officer, 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's objective is to delineate a potential 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 financing 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 (refer to Ontario Ministry of Energy and Mines, 2026).

The opportunity is underpinned by historical processing records indicating that the tailings were milled at an average feed grade of approximately 20 to 25 ounces per tonne silver, with recoveries of approximately 88 per cent. This implies that roughly 2.4 to 3.0 opt (approximately 75 to 95 grams per tonne) 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 testwork. These historical figures are unverified and conceptual in nature.

To date, the company has advanced several work streams in support of this objective.

• Tailings extent: The technical team has successfully mapped the physical extensions of the tailings.

• Active verification drilling: A dedicated sonic drill is currently executing a systematic drilling grid over these mapped extensions to confirm spatial and grade continuity.

• Comprehensive metallurgical testwork: In parallel with the active drill program, Brixton is preparing comprehensive metallurgical testwork. This analytical program will be conducted on representative samples from both the surface tailings environment and the hard-rock exploratory drill core to define optimized processing and recovery parametres across both material types.

• The current drilling and upcoming metallurgical testing are designed to systematically transition historical targets into a verified, compliant asset framework.

About the Langis project

An exploration target for the project has been identified in the range of 1.0 million to 2.0 million tonnes grading 400 g/t to 800 g/t silver. Note: the potential quantity and grade of the exploration target are conceptual. Insufficient exploration has been completed to define a mineral resource and there is no certainty that further exploration will result in the target being delineated as a mineral resource.
