Fortuna Intercepts 2.6 kg/t Ag and 10.8 g/t Au Over 3 m at Trinidad North Discovery, San Jose Mine, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 29, 2014) - Fortuna Silver Mines Inc. (NYSE:FSM) (TSX:FVI)(BVLAC:FVI)(FRANKFURT:F4S) is pleased to announce additional 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 March and April 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 230 meter strike extension of the Trinidad system and generally outside of the limits of the existing Inferred Resources.

Highlights of Step-out Drilling


  • 929 g/t Ag and 4.87 g/t Au (1,221 g/t Ag Eq) over ETW* of 4.5 m and
  • 1,808 g/t Ag and 13.21 g/t Au (2,601 g/t Ag Eq) over ETW of 4.1 m


  • 887 g/t Ag and 4.04 g/t Au (1,129 g/t Ag Eq) over ETW of 3.4 m


  • 2,573 g/t Ag and 10.77 g/t Au (3,219 g/t Ag Eq) over ETW of 3.0 m

Dr. Thomas I. Vehrs, Vice President of Exploration, commented: "The results of the step-out drilling at Trinidad North continue to confirm the presence of a robust mineralized system with excellent potential for further expansion. Particularly impressive are the results of drill hole SJOM-364 which encountered high-grade silver and gold mineralization at the extreme northern limit of the current drilling. This drill intercept is located 50 meters to the north of the previously reported high-grade intercept in drill hole SJOM-335 (3,511 g/t Ag and 15.04 g/t Au (4,413 g/t Ag Eq) over ETW of 3.7 m) (see Fortuna news release of January 21, 2014) and validates that the mineralized system remains open along strike to the north and to depth. The vertical extension of the mineralized zone currently exceeds 600 meters."

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 as of the July 4, 2013 data cutoff date were 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, January 21, 2014 and March 10, 2014. Drilling is currently being carried out from two underground drill stations located at the 1300 meter level with work 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 were successfully expanded to 2,000 tpd in April 2014 (see Fortuna news release of April 14, 2014) and investigations are currently underway to assess the potential for a further expansion to 3,000 tpd. Production for the first quarter of 2014 was 997,035 oz silver and 7,627 oz gold, 12 percent and 13 percent above budget, respectively. 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.
