Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. These mineral resource estimates include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied.

Mineral Resource Estimate Methodology

The mineral resource estimate for the Fireweed and Inferno North Deposits reported herein were prepared by Garth Kirkham, P.Geo. of Kirkham Geosystems Ltd., Burnaby, BC. The estimates were completed in MineSight ^{[ TM ]} using a three dimensional block modelling (10 metres by 10 metres by 3 metres (vertical) block size). The mineralization was interpreted into six distinct domains for Fireweed and one domain for Inferno North, modelled as wireframes and used as hard boundaries to constrain estimation. Geostatistical analysis was completed on the 1.5 metre composite assay data for each of the metals, and variograms were defined for each domain of mineralization. The grades for copper, gold and silver were interpolated into the block model using inverse distance to the second power. Interpolated results are reported in indicated and inferred categories and are based on continuity of the mineralization and sample density. The 1.2% base case cut-off grade was chosen for reporting due to the fact that this is the cut-off grade current being utilized for the underground reserves at the Minto site. It is anticipated that the Fireweed and Inferno North would potentially be mined using underground methods.
