LAURION Mineral Exploration Inc. (TSX-V: LME | OTC: LMEFF | FSE: 5YD) has provided an update on environmental, technical, and regulatory work supporting its 100%-owned Ishkōday Gold and Polymetallic Project in Northwestern Ontario. The company is advancing two complementary initiatives at the historical Sturgeon River Mine: recovery and remediation of a surface waste rock stockpile, and an Advanced Exploration Project involving dewatering and rehabilitation of the mine shaft. These efforts, backed by five years of environmental baseline studies and ongoing Indigenous consultation, position LAURION to potentially recover residual mineralization from legacy mining waste and gain underground access to evaluate historical gold-bearing structures that were not fully explored before mining ceased in 1942.
The surface stockpile recovery initiative matters because it represents a rare opportunity to extract value from decades-old mining waste while simultaneously remediating a legacy environmental liability. LAURION has submitted a Recovery of Minerals Permit application to the Ministry of Energy and Mines, including a Recovery and Remediation Plan under Ontario’s Mining Act. The stockpile contains mineralized material that can be recovered without new infrastructure or underground development, followed by remediation to provincial standards. This approach aligns with the company’s strategy of pursuing non-dilutive initiatives that enhance project development flexibility, as noted in its corporate update.

Separately, the proposed Advanced Exploration Project could provide critical geological insights. The historical Sturgeon River Mine shaft extends approximately 642 metres below surface with 15 underground levels and has been flooded since operations ceased, containing an estimated 114,000 cubic metres of static water. LAURION plans to remove the shaft cap, install a temporary headframe and hoisting plant, and conduct controlled dewatering to enable safe underground access. This would allow underground exploration drilling and sampling to evaluate the deposit’s potential. The company is preparing a Permit to Take Water application for submission to the Ministry of the Environment, Conservation and Parks in Q4 2026, supported by a detailed hydrogeological impact assessment. An Advanced Exploration Closure Plan and additional environmental approvals are targeted for early 2027.
The environmental baseline program, conducted over five years, included terrestrial ecology, aquatic and benthic studies, groundwater and surface water monitoring, shaft water characterization, and a Stage 1 Archaeological Assessment. These studies provide a foundation for regulatory review and will inform environmental management and monitoring measures. Indigenous engagement is being advanced through the Indigenous Joint Steering Committee and project-specific consultation with Animbiigoo Zaagi’igan Anishinaabek First Nation, Bingwi Neyaashi Anishinaabek First Nation, and Biinjitiwaabik Zaaging Anishinaabek First Nation. Public consultation will also occur as part of the Closure Plan process.
Management emphasizes the diligence behind these efforts. “Five years of rigorous, independent environmental baseline work is not a small undertaking,” said Cynthia Le Sueur-Aquin, President and CEO. “Recovering potentially economic residual mineralization within the stockpile, and doing so responsibly, is exactly the kind of value-additive, environmentally sound project our shareholders should expect.” She added that the dewatering program is expected to provide safe underground access for geological mapping and evaluation, and facilitate rehabilitation of a long-standing legacy mine hazard. No ore will be mined, processed, or sold as part of the dewatering program.
These developments are important because they demonstrate LAURION’s commitment to responsible resource development and could enhance the project’s economic potential while addressing historical environmental risks. Successful permitting and execution could lead to a better understanding of the mineralized system, potentially supporting a future Mineral Resource Estimate. The company’s focus on technical clarity and reduced execution risk positions it for long-term value creation in a prolific mining region.
