Fortuna intercepts 487 g/t Ag and 4 g/t Au over 8.2 m at Trinidad North discovery, San Jose Mine, Mexico
VANCOUVER, Aug. 15, 2013 /PRNewswire/ - Fortuna Silver Mines Inc. (NYSE: FSM | TSX: FVI | BVL: FVI | Frankfurt: F4S.F) is pleased to report results for twelve additional surface drill holes at the Trinidad North high-grade silver-gold discovery at the San Jose Mine in Mexico. With the exception of drill hole SJO-304, the reported drill holes are generally positioned to define the approximate limits of the Trinidad North ore shoot. The ore shoot remains open to depth and to the north with drilling from underground stations projected to start in early September.

Dr. Thomas I. Vehrs, Vice President of Exploration, commented, "The latest drill results continue to confirm the importance of the Trinidad North discovery. The Trinidad North ore shoot is located proximal to the area of operations at San Jose allowing for development of the zone in 2014 and initiation of production in early 2015. Silver equivalent grades range from 200 g/t to over 2,300 g/t over estimated true vein widths ranging from 2 meters to over 19 meters." Dr. Vehrs continued, "Underground access is currently in development at the 1300 meter level to allow for continued exploration of the ore shoot to the north and to depths below 1,000 m amsl. The first underground drill station is projected to be ready by the end of August with underground drilling scheduled to begin in early September."

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.
