Brixton Metals Company (TSXV: BBB,OTCCQX: PBXV) It said it has initiated a dedicated acoustic drilling campaign to determine a potential preliminary mineral resource estimate (MRE) of historical tailings at its wholly-owned Langis Silver project, located at a cobalt silver mining camp in northeastern Ontario, Canada.
The tailings program targets a potentially compatible resource to enhance the recovery and remediation plan and generate near-term cash flow, while two additional rigs are executing the company’s fully funded 60,000m foundation drilling program in 2026 to expand known mineralized areas and test unmined extensions, bringing the total to three rigs now active across the project.
2026 targets for the Langes Silver Project: Determine primary tailings mineral resource estimate (MRE) through dedicated acoustic drilling; Testing of structural targets and new unconformity targets for additional mineralization and expansion and filling of known high-grade silver zones to improve continuity.
“Commencing dedicated drilling for the Langis tailings is an important step towards identifying the first resource with the goal of generating near-term cash flow,” said Gary R. Thompson, Chairman and CEO. “With surface rights and patented claims already in place and a new recovery framework in Ontario, we are well positioned to advance this opportunity, while our core drilling rigs continue to expand high-grade silver potential across the broader property.”
An active on-site acoustic drilling rig is dedicated entirely to evaluating areas of historic tailings from operations spanning 1956 through 1968. The company’s goal is to determine a potential Mineral Resource Estimate (MRE), deliver 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 precious metals from historic mine waste while reducing the long-term environmental footprint of the legacy tailings facility. Successfully identifying a compatible resource could also provide non-dilutive financing to maintain and expand hard rock exploration operations over the long term across the wider Langes property.
This initiative is consistent with the Ontario government’s new regulatory framework for recovering residual metals from tailings and other mine waste. Effective July 1, 2025, Ontario’s mineral recovery regime under the Mining Act creates a simplified permitting process that allows eligible projects to proceed with a recovery permit in lieu of a full closure plan. Applicants must submit a recovery and treatment plan and meet applicable consent, counseling, financial assurance and regulatory requirements.
This framework aims to support faster metal recovery activities while maintaining health, safety and environmental protection.
This opportunity is supported by historical processing records which indicate that the tailings were milled to an average feed grade of approximately 20 to 25 oz/t silver, with a recovery of approximately 88%. This means that approximately 2.4 to 3.0 oz/t (about 75 to 95 g/t) of silver, representing the unrecovered balance, may remain in the older tailings, and this residual silver is the focus of the company’s tailings drilling and mineral testing work. These historical figures are unverified and are conceptual in nature.
To date, the company has developed several workflows to support this goal:
Extent of the waste: The technical team succeeded in mapping the physical extensions of the waste.
Active Verification Drilling: A dedicated acoustic drilling is currently carrying out a systematic drilling network on these mapped extensions to confirm spatial and grade continuity.
Comprehensive metallurgical testing works: In parallel with the active drilling programme, Brixton is preparing comprehensive metallurgical testing works. This analytical program will be conducted on representative samples from the surface tailings environment and hard rock exploratory drilling cores to determine optimal processing and recovery parameters across both material types.
Current drilling and upcoming mineral testing are designed to systematically convert historical targets into a compliant and verified asset framework.
Historical processing data from 1956-1968, including references to average feed grades of approximately 20 to 25 oz/t silver and potential recoveries of 88%, are historical in nature and based on operational records that have not been verified by a qualified person.
These estimates are used only as a guide to the current hazardous waste drilling program. The qualified person has not done adequate work to classify these historical estimates as current mineral resources, and Brixton does not treat them as current mineral resources. While Brixton is exploring to identify a potential mineral resource, it remains uncertain whether additional exploration will result in the target being successfully identified as an official mineral resource.
Brixton owns patented surface rights and claims covering the targeted tailings area, providing the company with direct access to legacy materials and reducing potential third-party land use restrictions.
The Langes project also benefits from strong regional infrastructure, with proximity to roads, power and railway lines and operating refineries and mills in the region. This existing ownership location and access to infrastructure enhances operational flexibility, helps reduce logistical complexity, and supports the effective progress of the company’s evaluation of waste reprocessing opportunities.
The 60,000m core drilling program at Langes is systematically targeting two key geological vectors known to control high-grade silver mineralization within the historic camp:
Unconformity-related silver veins: Historical production in the area shows that a significant portion of the economic silver mineralization is centered at or near the major regional unconformity between metamorphic volcanic rocks, metasedimentary rocks, and the Huronian Supergroup. Current drilling is focused on testing backfill locations within known mineral corridors and exit extensions along this horizon, which have not been tested by modern exploration techniques.
Regional Structural Trajectories: Structural modeling using reprocessed historical gravity data has identified key regional structures that are interpreted to serve as primary conduits for silver-bearing fluids. Two active rigs are currently testing these structural intersections at depth and along strike to identify potential new mineralization zones outside of historically mined areas.
The exploration target for the Langes project has been set at 1.0 million to 2.0 million tonnes of 400 g/t to 800 g/t silver.
The wholly-owned Langis Silver project, located approximately 500 kilometers north of Toronto, Ontario, includes a former producing mine and excellent infrastructure, including access to all-season roads, power, rail links, and a refinery.
Silver mineralization is found as native silver and in steep to moderately steep veins, veins, rosettes, and fracture fills, often associated with minerals such as calcite, hematite, pyrite, cobaltite, chalcopyrite, nicolite, and silver.
Mineralization is hosted across three major rock types: Keewatin Archean volcanic and metasedimentary rocks, sedimentary rocks from the Proterozoic Coleman Member of the Huronian Supergroup, and Proterozoic Nipissing rocks. The geological ore deposit model for this area is an extensional continental rift depositional environment. Intermittently from 1908 to 1989, the Langes mine produced 10.4 million ounces of silver with a primary grade of 777.5 g/t silver (25 oz/t).
Reported silver recoveries at Langis have been 88% to 98%. More than 10 km of underground workings have been developed by previous operators. However, the columns and openings were covered and sealed. Historically, the Cobalt Camp silver mines have collectively produced more than 445 million ounces of silver.
The 2026 program returned some of the strongest intervals reported by the company and the region to date.
Brixton has four exploration projects in its entirety: the major Thorne copper, gold, silver and molybdenum project, the Langis and Hudson Bay silver projects in Ontario, the Hog Haven copper, silver and gold project in northwestern Montana, USA, which has been selected for Ivanhoe Electric, and the Atlin Goldfields project in northwestern British Columbia, which has been selected for Eldorado Gold.
