Fortuna drills 7.3 m of 1789 g/t Ag and 10 g/t Au on northern extension of the San Jose mine, Mexico
VANCOUVER, April 22, 2013 /PRNewswire/ - Fortuna Silver Mines Inc. (NYSE: FSM) | (TSX: FVI) | (BVL: FVI) | (Frankfurt: F4S.F) is pleased to report that exploration drilling has successfully extended the Trinidad ore shoot to the north and to depth with mineralization remaining open in both directions. Results are also reported for the initial infill drilling being carried out in the central portion of the Trinidad deposit for purposes of conversion of Inferred Mineral Resources to an Indicated Mineral Resource classification.
Jorge A. Ganoza, President and CEO, commented, "We are excited by the consistency of the discovery holes drilled north of Trinidad, where we are starting to configure a new wide and high grade silver and gold mineralized shoot that remains open on two directions. Grades and widths of mineralization found are significantly higher than the average grade of existing reserves and resources. Our exploration team is giving priority to defining the controls and extent of this new zone, located within reach of current underground mine development."

Dr. Thomas I. Vehrs, VP of Exploration, commented, "Exploration drilling on the northern extension of the Trinidad deposit at the San Jose mine has confirmed the presence of high-grade silver and gold mineralization over wide vein widths. Drill hole SJO-283 intercepted strong mineralization at the 1010 meter elevation (approximately 520 meters below surface) and the mineralization remains open to the north and to depth."
Dr. Vehrs continued, "In addition to the continuation of the surface drilling, underground access is being developed to allow for the expansion of the exploration drilling to the north and to better test the extension of the mineralization to depth. The infill drilling being conducted in the central portion of the Trinidad deposit is also producing excellent results, with a number of drill holes reporting wide intervals of silver and gold mineralization associated with broad zones of crackle breccia and quartz-calcite vein stockworking. While these drill holes are largely consistent with prior wide spaced drill results, upgrading of the Inferred Resources will provide opportunity for incorporation of these materials into the Mineral Reserve category and the new mine plan update scheduled for the fourth quarter of this year."

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.
