ONTARIO – Northern Graphite Corp. of Ottawa is considering a concentrator twice the size of the one recommended in the feasibility study for the Bissett Creek graphite project, located between Ottawa and North Bay. As now contemplated, the mill would treat 5,580 t/d and produce 44,200 tonnes of concentrate annually.
The preliminary economic assessment done for the scenario with the larger mill, puts the pre-tax internatl rate of return at 31.7% and the pre-tax net present value at C$264.7 million using a base case with an 8% discount rate and average concentrate price of US$1,800 per tonne. The deposit contains 40.5 million tonnes grading 1.83% Cg (graphitic carbon) in what Northern calls “potential economically extractable resources.”
Capital costs of building an open pit with a 21-year life and mill are $134.1 million and sustaining capital comes to $55.1 million. The company says, “Almost 90% of production will consist of large and extra large flake and battery grade graphite which is by far the highest ratio in the industry.”
