BRITISH COLUMBIA – Avanti Mining of Vancouver has updated the feasibility study for its Kitsault moly property 140 km northeast of Prince Rupert to include a new open pit mine plan based on 2012’s resource model. The Kitsault property has three known molybdenum deposits, and was a producer in 1967-72 and 1981-82 during which time output totalled 31 million lb of moly.
The updated study is based on proven and probable reserves of 228.2 million tonnes grading 0.083% Mo (415.5 million lb) and 5.0 g/t Ag (36.6 million oz). Initial capital costs including working capital are estimated at $936 million, and sustaining capital will be $106 million. The costs cover an open pit mine and 40,000 t/d mill (SAG-ball milling, followed by conventional flotation and five stages of cleaning) that would operate for at least 16 years.
Avanti says that at a long term moly price of US$14.50/lb, the Kitsault project has an after tax net present value with an 8% discount of $433 million and a 16.6% internal rate of return. Total cash cost including milling and transportation will be $6.73 (US$626) per pound of molybdenum.
The Kitsault project is progressing through the environmental assessment process under the Nisga’a final agreement as well as provincial and federal legislation.
