TORONTO, ONTARIO--(Marketwired - March 12, 2015) - YAMANA GOLD INC. (TSX:YRI)(NYSE:AUY) ("Yamana" or "the Company") today announced the signing of a Definitive Agreement ("the Agreement") with the provincial Government of Catamarca, Argentina ("the Government"), represented by the provincial mining company Catamarca Mineria y Energetica Sociedad del Estado ("CAMYEN"). The Agreement advances the previously announced Memorandum of Understanding, which set the groundwork for cooperation to consolidate important mining projects and prospective properties in the province, most notably the Agua Rica property and the Cerro Atajo prospect, to create the Catamarca mining district ("the District"). The Agreement is the first of its kind between a provincial company and a private company in the Catamarca Province.

The signing of the Agreement provides the basis for further advancement of exploration and ultimately mining in the District. Yamana expects to use the existing workforce at Agua Rica to begin a planned exploration program in 2015 with a focus on Cerro Atajo. In addition, a plan is being implemented to train the existing workforce in Catamarca to ensure local communities have the opportunity to benefit directly from planned economic activity in the District.

The Company and the Government through CAMYEN will continue to evaluate the potential of Cerro Atajo and as the potential is confirmed a plan will be developed to improve and upgrade infrastructure in the District. Under the Agreement CAMYEN will receive up to a 5% interest in a combined entity, including the Agua Rica project and the Cerro Atajo prospect.

Agua Rica is a low cost, large-scale copper, gold, silver and molybdenum deposit located in the province of Catamarca, Argentina.

The Cerro Atajo prospect lies 10 km east of Alumbrera and 25 km west of Agua Rica, a region in which both Yamana and the Government have interests. The property is prospective for both high grade gold-copper-silver veins and large tonnage copper-gold porphyry mineralization. Cerro Atajo is centred on an intrusive complex within the same host rock as the nearby Alumbrera mine.
