Yamana Announces 44% Increase to Mineral Resources at Cerro Moro Provides Detail on Plans to Advance the Project TORONTO, ONTARIO -- (Marketwire) -- 02/13/13 -- (All amounts are expressed in United States dollars unless otherwise indicated.) YAMANA GOLD INC. (TSX:YRI)(NYSE:AUY)(LSE:YAU) ("Yamana" or "the Company") today provided an update on its Cerro Moro gold project (the "Project" or "Cerro Moro") in Santa Cruz, Argentina. Cerro Moro is a development stage project that was acquired in mid-2012 and is located in the Deseado area of the Santa Cruz Province, Argentina about 70 km southwest of the port city of Puerto Deseado. HIGHLIGHTS - Initial indicated mineral resource of 1.95 million gold equivalent ounces (GEO)(1), an increase of 44% from the previous estimate before the Company acquired the project, contained in 4.16 million tonnes with an average GEO grade of 14.6 grams per tonne (g/t); and an inferred mineral resource of 490,000 GEO contained in 3.60 million tonnes with an average GEO grade of 4.2 g/t - Initiation of the pre-development work and feasibility study leading toward a planned construction decision expected in 2014 and a potential start-up in 2016 - Evaluated as a combined open pit-underground operation with: - 1,000 tonnes per day (tpd) throughput - 70% from underground, 30% from open pit - Average annual production of approximately 200,000 GEO - Initiation of a further, extensive exploration plan in 2013 with one drill hole in January intercepting three separate vein zones with indications that two of these occur at mineable widths with the potential for significant GEO grades "Our objective is to produce high quality ounces with comparatively low costs to achieve growth in both production per share and cash flow per share. With our initial mineral resource at Cerro Moro, along with the initial operation plan and exploration potential, we are confident that this asset will contribute positively to that objective," commented Peter Marrone, Chairman and Chief Executive Officer. "We have started pre-development work with a production ready ramp into one of the ore bodies, the initial studies that will lead to a feasibility study and will continue with further exploration to advance the project. All of these tools will be considered in our construction decision. We are committed to deliver superior value to our shareholders and Cerro Moro will be a significant contributor to that." (1) Silver is treated as a gold equivalent at a ratio of 50:1. MINERAL RESOURCES & DEVELOPMENT PLAN In 2012, the Company spent $5 million to drill over 100 holes with the goal of upgrading the inferred mineral resources and grow the resource base. These results have been incorporated in the Company's mineral resource update for Cerro Moro. The Project hosts an initial indicated mineral resource of 1.95 million GEO and an inferred mineral resource of 490,000 GEO both at a 1 g/t cut-off. This cut-off grade reflects a blend of underground and open pit mining consideration. As mineral resources grow, with the expectation that the greatest potential is within those zones that will be mined from underground, the cut-off grade may be revised as the proportion of underground and open pit mineral resources changes and as the Project is further advanced. The table below shows the mineral resources at various cut-off grades. ---------------------------------------------------------------------------- Cut-Off Tonnes Au Ag AuEq Au oz Ag oz GEO (g/t) (000's) (g/t) (g/t) (g/t) (000's) (000's) (000's) --------------------------------------------------------------- 1.0 4,157 6.6 400.3 14.6 884 53,497 1,953 1.5 3,311 8.2 491.6 18.0 874 52,328 1,921 Indicated 2.0 2,962 9.1 542.4 20.0 869 51,651 1,901 2.5 2,777 9.7 573.5 21.2 864 51,204 1,888 3.0 2,681 10.0 591.2 21.8 861 50,949 1,880 3.5 2,602 10.3 606.2 22.4 858 50,703 1,872 4.0 2,500 10.6 626.4 23.1 852 50,346 1,860 ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- Cut-Off Tonnes Au Ag AuEq Au oz Ag oz GEO (g/t) (000's) (g/t) (g/t) (g/t) (000's) (000's) (000's) --------------------------------------------------------------- 1.0 3,598 1.9 115.9 4.2 222 13,408 490 1.5 2,904 2.3 134.2 5.0 212 12,535 463 Inferred 2.0 2,617 2.4 143.5 5.3 205 12,071 447 2.5 2,340 2.6 154.7 5.7 194 11,642 427 3.0 2,106 2.7 166.3 6.0 181 11,260 406 3.5 1,921 2.8 175.1 6.3 171 10,817 387 4.0 1,725 2.9 184.9 6.6 158 10,255 363 ---------------------------------------------------------------------------- Consistent with Yamana's focus on production that is more reliable and predictable, the Company will continue to prioritize planning and rely on appropriate expertise and experience in the development of projects to ensure efficient development while providing certainty of production and costs. The Company will use various tools including the application of expertise and experience gained from similar operations. In relation to Cerro Moro, the Company has engaged in pre-development work by way of a production ready decline into the largest of the known ore bodies, Escondida. In addition to advancing the timeline for development, this pre-development work will provide a platform for further exploration work and permit access to the ore body, providing greater certainty and knowledge of its physical properties and grade continuity. Technical and trade-off studies have been completed which support continuation to a feasibility level study for the project. Based on these studies, the feasibility study will consider a mine plan combining both open pit (30%) and underground (70%) mining operations to sustain a process plant with a throughput rate of approximately 1,000 tonnes per day and an expected recovery of approximately 200,000 GEO per annum. The feasibility study is expected to be completed sometime in 2014. The Company will then evaluate the results of the feasibility study together with current exploration results and the knowledge gained through the pre-development work to make a construction decision. Depending on the outcome of the studies and subsequent construction decision, production should begin in 2016. The underground mine will be accessed by means of conventional decline haulages, the first of which will be developed as part of the work completed prior to a construction decision and is consistent with the approach used at Mercedes. Since the mineralization is broadly similar to the Company's Mercedes operation in Mexico, mining and processing operations at Cerro Moro are expected to employ similar methods. Initial capital costs are expected to be below $400 million and operating costs are expected to be below $450 per ounce. The underground will be accessed through a conventional decline that will be developed as part of the work completed prior to a construction decision and is consistent with the approach at Mercedes. 2013 EXPLORATION The 2013 exploration program at Cerro Moro will focus on drill testing eight priority target areas located on the northern La Negrita block, an entirely new zone, and drill testing existing geologic targets, geochemical anomalies and vein extensions within nine priority target areas in the southern Escondida block, which contains the majority of current known mineral resources. The 2013 exploration drilling program at Cerro Moro commenced in mid-January and is already demonstrating success. One drill hole in January, which was intended to test the extension of an anomalous mineralization from prior holes, intercepted three separate vein zones, and preliminary indications are that two of these occur at mineable widths with the potential for significant GEO grades. Assays for these holes are still pending. This new discovery, the "Margarita" vein is within the La Negrita zone, which is outside of the area containing the known mineral resources. Drilling of this and all identified targets is expected to be ongoing throughout the year. The Company is expecting to spend $12 million in 2013 on exploration to execute the 25,000 metres of drilling with the goal of expanding the areas of mineralization to the La Negrita block and to add significantly to the mineral resource base. ABOUT CERRO MORO Cerro Moro comprises eighteen tenements covering an area of approximately 177 square kilometers. There are 8 sectors (Escondida, Loma Escondida, Zoe, Martina, Carla, Esperanza-Nini, Gabriela, and Deborah), all of which are located within the central portion of the Cerro Moro tenements, included in the current mineral resource. The Project consists of a series of low- to intermediate-sulfidation epithermal-style veins with locally high grade gold-silver mineralization, especially in the Escondida zone, which are hosted in sub-volcanic and volcanic rocks. This polymetallic gold-silver mineralization is similar to Yamana's operating mines El Penon and Mercedes.
