HudBay Advancing Reed Mine Project in Manitoba
Initial capital to develop the Reed mine is estimated at C$71.9 million. Run-of-mine ore will be transported by truck to HudBay’s Flin Flon concentrator, where it will be crushed to less than 150 mm. The Reed ore will be batched separately through the concentrator, with assumed metal recov-eries of 94% copper, 58% gold and 62% silver in a copper concentrate. Production from the Reed ores is expected to average 17,000 mt/y of copper in concentrate.
Access to the underground Reed mine will be via a trench, portal, and decline located near the center of the surface site. The decline will be excavated 6 m wide and 5 m high to a depth of 510 m from surface and will be able to accommodate a 60-mt truck. Mining levels will be spaced 25 m vertically and will be accessed from the decline. Level development will be 5.5 m wide by 4.5 m high to accommodate a 10-yd 3 Scooptram. Mining will be at a rate of 1,300 mt/d, using long-hole open stop-ing methods.
Infrastructure required at the Reed site includes an employee camp, mine office and changehouse dry, mechanical shop, warehouse, core shack, explosive maga-zine, electrical generator and fuel storage area, electrical office, ventilation downcast building, and compressor building.
As of March 30, 2012, the Reed pro-ject had probable minerals reserves totaling 2.2 million mt, grading 3.83% copper, 0.59% zinc, 0.48 g/mt gold, and 6.02 g/mt silver. HudBay and VMS are optimistic that additional resources can be developed down-dip from the current reserves.
