Fortuna drills 2.8 kg/t Ag and 14.5 g/t Au over a true thickness of 4.2 m at Trinidad North Discovery, San Jose mine, Mexico.
Vancouver, March 10, 2014: Fortuna Silver Mines Inc. (NYSE: FSM) (TSX:FVI) (BVL: FVI) (Frankfurt: F4S.F) is pleased to announce new results for step-out drilling of the Trinidad North discovery located contiguous with the San Jose mine in Oaxaca, Mexico. Assay results are included for eight drill holes completed in January and February of 2014. The results continue to confirm the extension of the Trinidad North zone with high-grade silver-gold mineralization present over wide vein widths. The results reported herein lie within a 200 meter strike extension of the Trinidad system and generally outside of the limits of the existing Inferred Resources.
Highlights of Step-out Drilling:
- 498 g/t Ag and 3.03 g/t Au (680 g/t Ag Eq) over estimated true width of 6.5 m
- 2,762 g/t Ag and 14.46 g/t Au (3,630 g/t Ag Eq) over estimated true width of 4.2 m
- 1,190 g/t Ag and 8.45 g/t Au (1,697 g/t Ag Eq) over estimated true width of 10.2 m
- 305 g/t Ag and 2.44 g/t Au ( 452 g/t Ag Eq) over estimated true width of 10.3 m
- 1,503 g/t Ag and 7.76 g/t Au (1,969 g/t Ag Eq) over estimated true width of 6.5 m and
- 600 g/t Ag and 4.20 g/t Au (852 g/t Ag Eq) over estimated true width of 18.8 m
Dr. Thomas I. Vehrs, Vice President of Exploration, commented: "The results of the step-out drilling at Trinidad North confirm the continuation of a very robust mineralized system with mineralization being present in two sub-parallel vein systems (Bonanza Vein and Trinidad Vein) and commonly in the form of stockwork zones between the two structures. The mineralization is closely associated with hydrothermal breccias formed as a result of boiling of the epithermal system with the evidence of boiling persisting to the deepest holes drilled to-date (approximately 600 m below current surface). The mineralization remains open to the north and to depth as well as vertically above the 1200 meter level."
The Trinidad North discovery was announced in February of 2013 (see Fortuna news release of February 4, 2013) and a maiden resource for the Trinidad North zone was announced in October of 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 October 17, 2013 news release for additional information. Step-out drilling of the Trinidad North discovery was initiated in late September of 2013 with initial results being reported in Fortuna news releases dated November 25, 2013 and January 21, 2014. Drilling is currently being carried out from two underground drill stations located at the 1300 meter level with preparations underway to advance the underground access a further 300 meters to the north to allow for further testing of the strike extension of the mineralized system.

San Jose Mine
The San Jose mine and processing plant are successfully operating at 1,800 tpd with expansion to 2,000 tpd projected for the start of the second quarter of 2014. Production guidance for 2014 is for the processing of 683,000 tonnes of ore averaging 203 g/t Ag and 1.56 g/t Au, resulting in the estimated production of 4.0 million ounces of silver and 30.4 thousand ounces of gold.
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.
