Yamana Gold : Updates Mineral Reserves and Mineral Resources for the Canadian Malartic Mine

TORONTO, ONTARIO--(Marketwired - Aug 13, 2014) -

(All amounts are expressed in United States dollars unless otherwise indicated.)

YAMANA GOLD INC. (TSX:YRI)(NYSE:AUY) ("Yamana" or "the Company") today announced updated mineral reserves and mineral resources for its 50%-owned Canadian Malartic mine. Yamana and Agnico Eagle Mines Limited ("Agnico Eagle") each acquired a 50% interest in the mine as part of the joint acquisition of Osisko Mining Corporation ("Osisko"), which was completed on June 16, 2014. The mine is operated by the Canadian Malartic General Partnership under a joint management committee.

The mineral reserves and mineral resources set out in this news release reflect the aggregate of Yamana and Agnico Eagle's 50% interests in the Canadian Malartic mine. Highlights of the updated Canadian Malartic mine mineral reserves and mineral resources are as follows:

• Proven and probable mineral reserves are 8.9 million ounces of gold based on a $1,300 per ounce engineered pit design, a cut-off grade between 0.28 g/t and 0.35 g/t gold, and a C$/US$ exchange rate of 1.10.

• The addition of the new 5% royalty payable to Osisko Gold Royalties Ltd. (OR:TSX) increased the highest cut-off grade to approximately 0.35 g/t gold from 0.33 g/t gold. This resulted in a decrease of about 60,000 ounces to the mineral reserve base from previous estimates published by Osisko.

• A $100 per ounce decline in the gold price would reduce the mineral reserves by approximately 3.3% or 310,000 ounces.

Further details on the updated mineral reserves and mineral resources are presented in the tables below.

Canadian Malartic mine mineral reserves and mineral resources as of June 15, 2014

Measured and indicated mineral resources are inclusive of mineral reserves. The assumptions used for the June 15, 2014 mineral reserves and mineral resources estimates at the Canadian Malartic mine were $1,300 per ounce gold, a cut-off grade between 0.28 g/t and 0.35 g/t gold (depending on the deposit) and a C$/US$ exchange rate of 1.10.

CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING ESTIMATES OF MEASURED, INDICATED AND INFERRED MINERAL RESOURCES

This news release uses the terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in and required to be disclosed by NI 43-101. However, these terms are not defined terms under Industry Guide 7 and are not permitted to be used in reports and registration statements of United States companies filed with the Commission. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of "contained ounces" in a mineral resource is permitted disclosure under Canadian regulations. In contrast, the Commission only permits U.S. companies to report mineralization that does not constitute "mineral reserves" by Commission standards as in place tonnage and grade without reference to unit measures. Accordingly, information contained in this news release may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations of the Commission thereunder.
