*Copper equivalent calculation represents the total metal value for each metal, multiplied by the conversion factor, summed and expressed in equivalent copper percentage. These
results are exploration results only and no allowance is made from recovery losses that may occur should mining eventually result. However it is the company's opinion that elements
considered here have a reasonable potential to be recovered. Prices and conversion factors are summarized below;
Copper Equivalent Formula = Cu % +Co (ppm) x 0.0008*
Price Assumptions - Cu (US$1.60/lb), Co (US$16/lb)
*Conversion Factor 0008 = (Co 16/Cu 1.60)/10000 in order to convert ppm Cobalt to % Cobalt.
