Adex Mining Appeals Regulatory Action

Adex Mining Inc. filed an appeal with the New Brunswick Energy and Utilities Board (NBEUB) on July 29, 2026, contesting the July 13, 2026 cancellation of Mineral Claim 1505. The claim hosts the Mount Pleasant mining project and was cancelled by the Mining Recorder for alleged failure to meet required work program expenditures under the Mining Act.

Adex argues the cancellation contradicts prior written guidance and the company's ongoing strategic review process, alleging the Recorder imposed arbitrary deadlines and ignored good-faith compliance proposals. The company seeks an interim stay, a setting aside of the cancellation notice, reinstatement of the claim, and regulatory directions to complete required expenditures.

The claim remains in "protected status" under s. 52(4) of the Mining Act pending discussions regarding a potential transaction, aligning with the Special Committee's previously announced strategic review. Adex will seek clarification on the protected status and provide updates as regulatory engagement progresses.

Adex Mining Inc. (ADE) disclosed the cancellation of Mineral Claim 1505 on July 14, 2026, and the market had already priced in this development. The company filed an appeal on July 29, 2026, which serves as a standard procedural follow-up rather than a new market-moving event.

Financial data indicates a severe liquidity crunch for the company. Adex Mining Inc. holds approximately $225,000 CAD in cash against $7.08 million in debt, and a going concern flag is actively disclosed. This financial reality underscores the company's inability to fund the required work program expenditures or service its maturing debt.

The regulatory action highlights the company's difficulty in maintaining its sole asset in good standing. The appeal is viewed as a defensive measure with a low probability of success given the documented expenditure shortfalls and the company's financial constraints. While the impact is negative, it is incremental, as the core asset risk was already materialized in the prior release.

Adex Mining Inc. (ADE) is a Canadian exploration and development company headquartered in Toronto, Ontario. Its flagship asset is the Mount Pleasant Mine Property in New Brunswick, Canada, which is divided into the Fire Tower Zone, containing tungsten, molybdenum, and bismuth, and the North Zone, which hosts tin, indium, and zinc.

The dormant mine is currently under care and maintenance, with a prefeasibility study and environmental permitting on hold pending improved market conditions. Historically, the Fire Tower Zone produced approximately 1 million tonnes of tungsten between 1983 and 1985. Existing infrastructure includes crushing and processing facilities, tailings ponds, and metallurgical buildings.

NI 43-101 compliant estimates indicate 13.5 million tonnes of indicated tungsten and molybdenum in the Fire Tower Zone and 12.4 million tonnes of indicated tin, zinc, and indium in the North Zone.
