Brixton's Silver Bonanza Paves Way for Maiden Resource at Langis Project

COBALT, ON – June 16, 2026 – In the world of mineral exploration, drill results are the currency of progress, translating geological potential into tangible value. Today, Brixton Metals Corporation (TSX-V: BBB, OTCQX: BBBXF) made a significant deposit into that account, announcing exceptionally high-grade silver intercepts from its ongoing exploration at the Langis Project in Ontario’s historic Cobalt silver camp. The results not only confirm the presence of bonanza-grade silver but also signal a critical shift in the project's potential scale, accelerating its journey from a historic mine to a modern, commercially viable asset.

The latest findings are a key milestone in Brixton's ambitious 2026 drill campaign, a massive undertaking aimed squarely at defining a maiden mineral resource estimate for the project. This step is the linchpin in the transition from exploration to development, providing the verified data necessary to attract further investment, secure potential partnerships, and ultimately, build a mine.

Unearthing Bonanza Grades and Bulk Potential

The headline numbers from Brixton's latest announcement are impressive by any industry standard. Hole LM-26-342, drilled in the Shaft 6 South area, hit a wide zone of 23.7 meters grading 206.6 grams per tonne (g/t) silver. Within that larger interval, the company intersected a remarkable 1.8 meters grading 1,329 g/t silver—a grade that signifies extremely rich, direct-shipping ore potential. To put that in perspective, a grade of 300 g/t is often considered high-grade for an underground silver mine.

Similarly, hole LM-26-355 in the nearby Shaft 6 Southeast area returned 4.95 meters of 492.8 g/t silver, which included a core-length of one meter assaying a spectacular 1,798 g/t silver. These results build upon a series of successful intercepts reported throughout the 2026 program, consistently demonstrating the project's capacity to deliver kilogram-plus per tonne silver values.

Perhaps more significant for the project's long-term commercial prospects is the geological nature of the mineralization. While the Cobalt Camp is famous for its high-grade, narrow veins of native silver, Brixton's drilling has also identified disseminated silver mineralization—fine particles of silver spread throughout the host rock. This is a potential game-changer for Langis.

As Chairman and CEO Gary R. Thompson stated, “it is also promising to observe disseminated silver mineralization, as it’s generally associated with large-scale, bulk-tonnage potential.” This discovery opens up the possibility of a much larger mining operation than one that solely targets narrow veins, fundamentally altering the economic model and expanding the project's scope. The combination of high-grade veins, which can provide early cash flow and boost project economics, with a broader, bulk-mineable resource is a powerful duo for any aspiring miner.

A Strategic Push Towards a Maiden Resource

These compelling results are not happening in a vacuum. They are the product of a highly focused and aggressive strategy to fast-track the Langis Project toward a pivotal commercial milestone: its first-ever NI 43-101 compliant mineral resource estimate. This formal declaration of tonnes and grade is the foundation upon which all future economic studies, financing efforts, and development plans are built.

To achieve this, Brixton has embarked on what locals have reportedly called the largest drill campaign the Cobalt Camp has seen from any single company. The company plans to drill a total of 60,000 meters in 2026, and with nearly 19,000 meters already completed, the pace is accelerating. “The second drill is now operational to meet our goal of 60,000 meters of drilling at Langis this year as we advance toward a maiden resource estimate,” Thompson confirmed. This significant capital deployment underscores management's confidence in the asset and its commitment to moving it up the value chain.

While the company has outlined a conceptual exploration target of 1.0 to 2.0 million tonnes grading between 400 and 800 g/t silver, the current drill program is designed to convert that potential into a defined, bankable resource. This is the critical step that separates promising prospects from projects with a clear path to profit.

Revitalizing a Storied Silver District

Brixton's modern exploration success is unfolding on historically rich ground. The Cobalt Camp has collectively produced over 445 million ounces of silver, and the Langis mine itself was a significant contributor, producing 10.4 million ounces at a very high average grade of 777.5 g/t silver between 1908 and 1989. However, past operators focused primarily on the most accessible, highest-grade veins.

Brixton is leveraging modern geological understanding and exploration technology to unlock potential that was previously overlooked. The identification of disseminated silver and the extension of known mineralized zones, such as in the Shaft 6 Southeast area which has no known historic stopes, demonstrates how a fresh perspective can breathe new life into a mature mining district. Furthermore, the project benefits immensely from its brownfield status. The existence of excellent infrastructure, including all-season roads, power, and nearby rail, dramatically reduces the capital hurdles and timelines typically associated with building a new mine from scratch in a remote location. This inherited infrastructure provides a significant, unwritten commercial advantage.

De-Risking the Path to Production

For investors and potential partners, the credibility of exploration results is paramount. Brixton is following rigorous industry-standard Quality Assurance and Quality Control (QA/QC) protocols to ensure the data's reliability. Core samples are processed and analyzed at ALS Minerals Laboratories, an ISO-certified facility, and all technical information is reviewed and verified by an independent Qualified Person, Mr. Martin Ethier, P.Geo.

This meticulous approach to data verification is a crucial, non-negotiable step in de-risking the project. While Brixton Metals maintains a diversified portfolio of promising assets, including projects optioned to major players like Ivanhoe Electric and Eldorado Gold, the strategic focus on rapidly advancing Langis highlights its standout potential. The combination of near-surface, high-grade mineralization and a clear path to a maiden resource makes Langis a primary engine for value creation within the company, demonstrating a clear-eyed strategy to translate drill-bit success into commercial reality.
