Lac Rocher
![]() Discovered in 1999, the Lac Rocher sulphide nickel deposit is located in northern Quebec some 140 kilometres northeast of the village of Matagami and about 50 kilometres east of paved Highway 109.
The Lac Rocher nickel discovery occurs in the zoned, unmetamorphosed "Discovery Intrusion" that is in sharp intrusive contact with the enveloping country rock. The 3.2 metre massive sulphide intersection at the footwall contact of the intrusion obtained from drill hole NLR-99-01 returned a weighted average of 10.8% nickel as part of a 61.5 m interval grading 1.69% nickel. Substantial sulphide mineralization (>8%) has been intersected over a 175 m interval at the north end on the Discovery Intrusion where it occurs as massive lenses and disseminations and coarse aggregates of pyrrhotite, pentlandite, chalcopyrite, and minor pyrite. There is a Measured & Indicated NI 43-101 compliant resource of 0.8 million (M) tonnes grading 1.12% Ni for 20M lbs of nickel, and an Inferred Resources of 0.44M tonnes grading 0.65% Ni for another 6M lbs of nickel, all at 0.5% nickel cut-off.
The PEA shows that metal prices of US$9.74/lb nickel, US$3.65/lb copper and US$30.43/lb cobalt (at an exchange rate of Cdn$1.00:US$0.95) are necessary for the project to break even on a pre-tax, 100% equity basis. The Company is re-visiting the calculations in the PEA with respect to the current commodity-price environment and higher Canadian dollar. The PEA envisions the Lac Rocher deposit being contract mined in two phases using mechanized cut-and-fill mining over a span of 24-26 months. In Phase One, 65,000 tonnes would be extracted at 1.75% nickel, 0.57% copper and 0.062% cobalt; in Phase Two an additional 252,730 tonnes would be extracted at 1.52% nickel, 0.59% copper and 0.051% cobalt. All extracted material is assumed to be transported offsite to the Copper Rand mill in Chibougamau , Quebec. In addition to those noted above, the December 2008 PEA was based on the following parameters:
The Company intends to maintain the project in a condition that will allow it to be quickly advanced to production when justified by metal prices. To that end, an Environmental Impact Study (EIS) has been submitted and construction of an access road completed. The PEA includes the use of inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that any value from such resources will be realized in whole or in part. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation or other relevant issues.
