CAUTIONARY NOTE REGARDING RESOURCE ESTIMATES The mineral resource estimate for Los Azules was calculated in accordance with the Canadian National Instrument 43-101 and the Canadian Institute of Mining and Metallurgy Classification system. These standards differ significantly from the requirements of the U.S. Securities and Exchange Commission for descriptions of mineral properties in SEC Industry Guide 7 under Regulation S-K of the U. S. Securities Act of 1933. In particular, under Guide 7 standards, mineral resources may not be classified as a “reserve” unless the determination has been made that mineralization could be economically and legally produced or extracted at the time the reserve determination is made.
