Technical and Project Information

The Los Azules Report is available under the Corporation's profile on SEDAR (www.sedar.com).

The Los Azules Report is preliminary in nature and includes the use of inferred resources which are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Thus, there is no certainty that the results of the preliminary assessment in the Los Azules Report will be realized. Actual results may vary, perhaps materially. The level of accuracy for this preliminary assessment estimates is approximately +/- 35%.
