There are currently four other significant gold targets (e.g., Iris Lake, Goldie Zone, Burchell West and Span Lake) on the Property which are not part of the current resource estimates. The Report was prepared by Wardrop, a Tetra Tech Company (Wardrop) and incorporates over 26,000 m of drilling that was completed on the deposit. Foundation is the operator of this project and owns 60% interest in the Property. Alto owns the remaining 40%.

Indicated and Inferred resources have been determined for the East Coldstream Deposit (see Table 1 in link below). At a cut-off grade of 0.4 g/t gold and using the Inverse Distance Squared (ID2) estimation method, the two parallel gold horizons contain an Indicated Resource of about 3.5 million tonnes with an average grade of 0.85 g/t gold. In addition, the Inferred Resource totals approximately 30.5 million tonnes with an average grade of 0.78 g/t gold. Table 1 provides a summary of the Resource Estimate at the 0.4 g/t cut-off.
