Goldcorp’s Borden Gold Project near Chapleau has filed an Advanced Exploration Closure Plan. Goldcorp is planning to extract a bulk sample of roughly 30,000 tonnes of rock to be assayed and analyzed. In order to perform this bulk sample, a portal and small ramp will be constructed. This bulk sample is required as part of the pre-feasibility work for a mine. This work will begin in late 2016 or early 2017 if all is approved.
From the Closure Plan:
“The following are the major components of this Closure Plan as proposed by Goldcorp:
• Development of a new portal and ramp for extraction of a bulk sample, about 30,000 tonnes;
• Stockpiling of mine rock from portal / ramp development;
• Temporary stockpiling of the bulk sample material (within the mine rock stockpile area), with haulage off-site for testing;
• Collection and diversion berms to facilitate the separation of mine rock and bulk sample material “ contact” water from natural surface runoff;
• Construction and operation of a new Collection Pond and treatment of “contact” water comprising: underground mine water, mine rock and bulk sample material stockpile runoff, and general site runoff;
• Mobile water treatment facilities involving pH adjustment and/or flocculent addition;
• Installation of a mine water effluent discharge pipeline, routed to the west to Borden River;
• Operation of two diesel generators, with up to 4.1 megawatts (MW) of power supply, and one backup diesel generator;
• A maintenance shop for upkeep of large haul trucks;
• A septic tank and raised tile field bed; and
• Temporary (mobile) service buildings, including office triers (should read trailers?) and mine dry.”
