The mineralized area extends over an area of 12 kilometers in length and up to 4 kilometers in width. Mineralization consists of irregular lenses scattered along the contact between the limestone and argillite. The fluorite area contains a historical resource of 2.6 million tonnes grading 30% CaF2 (of which Rocher Deboule has optioned the northern section) as reported on page 291 of the 1986 Report on Canadian Mineral Deposits, Energy, Mines and Resources Canada. The main showing on the Tam deposit is reported to have indicted potential of more than 450,000 tonnes averaging 36.7% CaF2 as reported in Minefile No. 094M 005.

Where historical estimates are referred to, the Company has no classification of the resource or reserve, and the Company has not obtained enough of the original data and has not done the work necessary to verify the classification of a resource or reserve. The Company is not treating the estimates as a NI 43-101 defined resource or reserve verified by a qualified person, and the historical estimates should not be relied upon.
