MANITOBA – CROWFLIGHT MINERALS of Toronto is studying an expanded throughput scenario for its Bucko Lake nickel project near Wabowden, Man., in the Thompson Nickel Belt. The company is considering a 50% increase, to 1,500 t/d, from the figures in the bankable feasibility study. Production would begin Q3 2009.
The additional cost involved with the expanded throughput option is estimated at $8.5 million on top of the earlier capital cost estimate of $64.0 million (see CMJ Net News for Feb. 7, 2007). Average annual cash flow would rise to $78.0 million from the earlier estimate of $55.1 million if the price of nickel is US$8/lb.
The bankable feasibility study announced on April 24, 2007, envisioned an underground mine using a rehabilitated, three-compartment shaft on the property plus an internal ramp system for access, with mining by longhole stoping. The concentrator is expected to recover approximately 81% of the contained nickel to produce on average 12.5 million lb of contained nickel in concentrate per year over an eight-year mine life. Production is scheduled to commence in the second quarter. The proven and probable reserve totals 2.3 million t grading 1.84% Ni.
The expanded project will include a decline to connect the surface with the underground ramp, a past backfill plant, and extra infrastructure (ventilation, pumping, etc). Additional information is posted at www.Crowflight.com.
