Amex Gold Mining Inc. (TSXV: AMX; OTCQX: AMXEF) has filed a Project Notice for its proposed Perron Gold Mine with Québec’s Ministry of the Environment.
The submission formally begins the provincial environmental impact assessment process for the proposed underground mine near Normétal in the Abitibi region.
Environmental Review Begins
The Project Notice provides provincial authorities with an overview of the proposed mine, including its underground operations, surface infrastructure, environmental setting and general design.
After completing its administrative review, the Ministry of the Environment, the Fight Against Climate Change, Wildlife and Parks will issue a directive specifying the information Amex must include in its Environmental Impact Assessment.
Amex said it has already started environmental baseline studies, engineering work, technical evaluations and stakeholder engagement in preparation for the assessment.
Filing the notice does not constitute environmental approval or authorize construction of the mine. The project remains subject to the assessment process, consultations and additional government decisions and permits.
Phase 1 Uses Regional Processing Capacity
The proposed operation is based on Amex’s Phase 1 feasibility study, released in April and supported by an NI 43-101 technical report filed in May.
The study outlines an underground operation producing approximately 1,100 tonnes per day, with ore processed at an existing regional facility through a toll-milling arrangement.
Phase 1 Proven and Probable Mineral Reserves total 1.989 million tonnes grading 12.1 grams per tonne gold, containing approximately 774,500 ounces.
Amex projects average annual production of approximately 147,000 ounces over five years of commercial operation. The study estimates an all-in sustaining cost of US$910 per ounce and initial capital spending of C$193.9 million, before accounting for a projected C$68.1 million in pre-production revenue.
Using an assumed gold price of US$3,500 per ounce and a C$1.38-to-US$1 exchange rate, the study calculated an after-tax net present value of C$1.13 billion and an after-tax internal rate of return of 114.6%. These figures are projections based on study assumptions and are not guaranteed.
Amex is separately advancing construction of a permitted 40,000-tonne bulk-sample program. The company said the program will provide geological, geotechnical, metallurgical and operating data that could inform future mine development.
The Project Notice moves Perron into Québec’s formal environmental review process, but the project’s construction and production timeline will depend on the assessment outcome, additional approvals, financing and execution of the proposed development plan.
