Brixton Metals (TSXV: BBB) has started a dedicated sonic drilling campaign at its Langis Silver Project, aiming to define an initial mineral resource estimate from historic tailings left behind by decades of past mining.
The program adds a third rig to the project, joining two bedrock rigs already advancing a fully funded 60,000-metre drill program for 2026.
The tailings effort is its own animal. A single sonic rig is working the waste material from operations that ran between 1956 and 1968, drilling a systematic grid over mapped tailings extents to test for grade and continuity. The goal is a compliant resource that could support a Recovery and Remediation Plan and, eventually, near-term cash flow.
Historical processing records suggest the tailings were milled at roughly 20 to 25 ounces per tonne silver at about 88% recovery, implying that something in the order of 75 to 95 g/t silver may still sit in the legacy material.
“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,” said Gary R. Thompson, Chairman and CEO. He noted that surface rights and patented claims are already in hand, and pointed to Ontario’s new recovery framework as a reason the company is well positioned to advance the work while its bedrock rigs continue chasing high-grade silver elsewhere on the property.
That framework is key to the strategy being put into place. Effective July 1, 2025, Ontario’s Recovery of Minerals regime under the Mining Act created a streamlined permitting path, letting qualifying projects proceed with a recovery permit instead of a full closure plan, provided they meet consultation, financial assurance and environmental requirements.
Brixton is also preparing metallurgical test work on samples from both the tailings and hard-rock drill core to refine processing and recovery parameters.
Alongside the tailings work, the bedrock program is targeting unconformity-related silver veins and regional structural pathways, testing infill positions and step-out extensions across the historic camp. The company has framed an exploration target of 1.0 to 2.0 million tonnes grading 400 to 800 g/t silver, a figure it describes as conceptual.
