Step-out drilling extends high-grade mineralization at Fortuna Silver's Trinidad North discovery
November 25, 2013: Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) (BVL: FVI) (Frankfurt: F4S.F) is pleased to announce assay results for the initial step-out drilling of the Trinidad North discovery located adjacent to the San Jose Mine in Oaxaca, Mexico. Three drill holes have been completed to-date with assay results currently being available for the first two drill holes, representing step-outs of approximately 80 and 150 meters from prior drill holes.
Highlights of Step-out Drilling
|Hole_Id||From (m)||To (m)||Interval (m)||ETW* (m)||Ag (g/t)||Au (g/t)||Ag Eq** (g/t)|
* ETW = estimated true width
**Ag Eq values calculated at Au:Ag ratio of 53.37 based on metal prices as of Dec. 31, 2012 (Au: US$1572.19; Ag: US$29.46) and metallurgical recoveries of 89 percent for both Au and Ag
Step-out drilling of the Trinidad North discovery was initiated in late September following the completion of underground access and drill stations at the 1300 meter level with two drill rigs currently exploring the extension of the mineralized shoot to the north and to depth.
Dr. Thomas I. Vehrs, Vice President of Exploration, commented: "The results of the initial step-out drilling at Trinidad North confirm the extension of a robust mineralized system to the north. The mineralized zones are characterized by strong development of hydrothermal breccias and quartz vein stockworks containing high-grade gold-silver mineralization. The system remains open to the north and to depth and we eagerly look forward to the results of this exciting program. With two drill rigs now operating, we anticipate being able to complete 8 drill holes by the end of 2013 with results being available by mid-January. This drilling will provide an initial indication of the resource potential of a 200 meter extension of the Trinidad North zone as well as testing the potential for mineralization to depths below the 900 meter level. Drilling planned for 2014 will test a further 300 meter extension of the structure for a total of 500 meters from the northern limit of existing Inferred Resources."
Trinidad North Discovery
A maiden resource estimate for the Trinidad North discovery was announced by Fortuna in October 2013. At a 70 g/t Ag Eq cutoff, Inferred Resources at Trinidad North are estimated at 1.9 Mt averaging 269 g/t Ag and 1.67 g/t Au, containing 16.3 Moz Ag and 100.8 koz Au. Resource estimates at higher cutoff grades were also presented and the reader is referred to the Oct. 17, 2013 news release for additional information.

San Jose Mine, Mexico
The expansion of the San Jose Mine's processing plant capacity to 1,800 tpd was successfully completed and commissioned in September of this year on-time and on-budget. The mine is on schedule to meet its annual production guidance of 2.4 million ounces of silver and projects to be 10 to 12 percent below guidance of 20,900 ounces of gold for 2013.
Quality Assurance & Quality Control
Following detailed geological and geotechnical logging, drill core samples are split on-site by diamond sawing. One-half of the core is submitted to the ALS Chemex Laboratory in Guadalajara, Mexico. The remaining half core is retained on-site for verification and reference purposes. Following preparation, the samples are assayed for gold and silver by standard fire assay methods and for silver and base metals by ICP and atomic absorption methods utilizing aqua regia digestion. The QA-QC program includes the blind insertion of certified reference standards and assay blanks at a frequency of approximately 1 per 15 normal samples as well as the inclusion of duplicate samples for verification of sampling and assay precision levels.
