Pretivm Resources Inc.: Positive PEA for Brucejack Gold Project


VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 2, 2011) - Pretium Resources Inc. ("Pretivm") (TSX:PVG) is pleased to report positive results from a National Instrument 43-101-compliant Preliminary Economic Assessment ("PEA") for the high-grade gold and silver resources identified to date at its Brucejack Project in northern British Columbia. The PEA was prepared by Wardrop, a Tetra Tech Company (Wardrop).

  • PEA Highlights
    • Base case estimated pre-tax Net Present Value (5% discount) of US$662 million and internal rate of return of 27.1%, using US$1,100/oz gold and US$21/oz silver;
    • Mine life of 16 years, with an average processing rate of 1,500 tonnes/day;
    • Annual average production for first ten years of 173,200 ounces of gold and 1.12 million ounces of silver;
    • Estimated capital cost, including contingencies, of US$281.7 million.

Production and Processing

The Brucejack high-grade project is planned to commence as an underground mining operation, with small-scale open pit mining commencing near the depletion of the underground mining inventory. The estimated underground mining inventory is comprised of 6.16 million tonnes of mineralized material with an average mill feed grade of 10.5 grams per tonne gold and 87.26 grams per tonne silver. The remaining inventory is comprised of 2.26 million tonnes of mineralized material from the open pits with an average mill feed grade of 3.35 grams per tonne gold and 35.95 grams per tonne silver.

The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied that would enable them to be categorized as mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There is no certainty that the PEA will be realized.

Gold-silver doré will be produced using a combination of conventional bulk sulphide flotation, gravity concentration and cyanidation, with gold and silver recovery by the Merrill-Crowe process. A total of 2.16 million ounces of gold and 14.72 million ounces of silver will be produced over the life of mine. The following table summarizes the production and processing parameters:

Capital and Operating Costs

The total estimated capital cost for the Brucejack high-grade project is US$281.7 million and the estimated operating costs are C$158.36 per tonne milled for underground mining and C$68.77 per tonne milled for open pit operation. The following tables summarize the cost components:

Brucejack Project Update

Upon completion of the 2011 drill program now underway at Brucejack, a new mineral resource estimate for the project's high-grade gold and silver resources will be prepared which will form the basis for an updated Preliminary Economic Assessment. Concurrent with the preparation of an updated PEA, which is planned to commence in Q4 2011, Pretivm will either proceed with a pre-feasibility study or advance directly to a full feasibility study for the Brucejack Project high-grade development opportunity.

Ian I Chang, M.A.Sc., P.Eng., Vice President, Project Development, Pretium Resources Inc. is the Qualified Person (QP) responsible for Brucejack Project development.
