Fortuna Silver Reports Updated Mineral Resource Es

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug. 27, 2014) - Fortuna Silver Mines Inc. (NYSE:FSM)(TSX:FVI)(BVLAC:FVI)(FRANKFURT:F4S) is pleased to announce an updated Mineral Resource estimate as of June 30, 2014 for the San Jose Mine located in Oaxaca, Mexico. Included in the San Jose mineral resources is an updated estimate of the Mineral Resource for the Trinidad North discovery based on the completion of forty-one additional step-out and twelve infill drill holes in the Trinidad North area.

Highlights of Mineral Resource Update

• Measured and Indicated Resources total 5.8 Mt containing an estimated 42.3 Moz silver and 334 koz gold, reflecting increases of 42 percent in contained silver ounces and 29 percent in contained gold ounces relative to the July 4, 2013 resource estimate.

• Inferred Resources total 7.1 Mt containing an estimated 58.9 Moz silver and 401 koz gold, reflecting increases of 67 percent in contained silver ounces and 47 percent in contained gold ounces relative to the July 4, 2013 resource estimate.

Above estimates of Mineral Resources are stated at a 100 g/t Ag Eq cutoff with Ag Eq in g/t = Ag (g/t) + Au (g/t)*((US$1,260/US$21)*(89/89)).

"Brownfields exploration drilling has been very successful in the past year at extending the Trinidad North mineralization a further 200 meters to the north," commented Dr. Thomas Vehrs, Vice President of Exploration for Fortuna Silver. "High-grade silver-gold mineralization at Trinidad North remains open to the north and to depth. Underground access and new drilling chambers are currently in preparation to allow for exploration of an additional 250 meter extension of the mineralized system with drilling projected to start from the new drill chambers in September of 2014."

Step out drilling of the Trinidad North Discovery during the latter half of 2013 and the first half of 2014 confirmed the continuation to the north and to depth of the Bonanza and Trinidad vein structures, as well as identified three new mineralized domains comprising two new Stockwork Zones and a new Trinidad Footwall vein. These contributed 3.6 Mt of Inferred Resources averaging 387 g/t Ag Eq containing an estimated 45.3 Moz Ag Eq. In addition the step out drilling resulted in the re-interpretation and adjustment of existing Inferred Resources contributing a further 1.4 Moz to the resource inventory.

Infill drilling of the previously established Stockwork Zone in conjunction with underground developments in previously unclassified areas resulted in the discovery of 0.6 Mt averaging 310 g/t Ag Eq containing an estimated 6.3 Moz Ag Eq. The infill drilling also led to adjustments to the geological interpretation of existing Inferred Resources resulting in an additional 5.1 Moz Ag Eq. Geological re-interpretation of secondary veins contributed a further 0.6 Moz Ag Eq.

Taking into account production related depletion of 5.1 Moz Ag Eq and a decrease in existing resources containing 2.8 Moz Ag Eq resulting from a change in the reporting cut-off grade from 70 g/t Ag Eq to 100 g/t Ag Eq to better align the resource reporting cutoff grade with the mine operating costs, contained silver equivalent ounces in the Measured and Indicated classifications increased by 18.2 Moz Ag Eq to 62.4 Moz Ag Eq while contained silver equivalent ounces in the Inferred classification increased by 32.6 Moz Ag Eq to 82.9 Moz Ag Eq. For comparative purposes, a copy of the San Jose Mineral Resources as of July 4, 2013 is included in the appendix to this news release.

Trinidad North Discovery

Included in the above reported resources at a 100 g/t Ag Eq cutoff are Indicated Resources totaling 0.5 Mt containing 6.3 Moz of silver and 41.3 koz of gold along with 4.8 Mt of Inferred Resources containing 43.5 Moz silver and 278.8 koz gold corresponding to the Trinidad North discovery.

The above tables summarize the Trinidad North Indicated and Inferred Resources at a range of Ag Eq cutoff values. Of significant importance is the presence of high-grade mineralization in the Trinidad North Discovery. As shown, silver and silver equivalent grades increase substantially at cutoff grades of 100 g/t Ag Eq or higher.

Estimation Methodology

Drill hole and channel samples were used in conjunction with underground mapping to construct three dimensional wireframes defining individual vein structures. Samples were selected inside these wireframes, coded and composited. Boundaries were treated as hard with statistical and geostatistical analysis conducted on composites for each vein. Silver and gold grades were estimated into a geological block model representing each vein. Primary veins including Bonanza, Trinidad, Fortuna and the Stockwork Zone were estimated by Sequential Gaussian Simulation. Secondary veins were estimated by inverse power of distance. Estimated grades were validated globally, locally, and visually prior to tabulation of the Mineral Resources.

San Jose Mine

The San Jose mine and processing plant were successfully expanded to 2,000 tpd in April of 2014 (see Fortuna news release of April 14, 2014) and studies are currently underway to assess the potential for a further expansion to 3,000 tpd. Production for the first half of 2014 was 2,098,446 oz silver and 15,583 oz gold, 10 percent and 8 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.

Updated Mineral Reserves for the San Jose Mine are currently in preparation and will be reported upon completion.

Quality Assurance & Quality Control

Following detailed geological and geotechnical logging, all exploration and infill 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 by standard fire assay methods with an atomic absorption finish and for silver and base metals by standard ICP methods utilizing aqua regia digestion. Over limit values for gold and silver are assayed for fire assay methods with a gravimetric finish. 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. Field duplicate, laboratory duplicate and preparation duplicate samples are included for purposes of verification of sampling and assay precision levels. Pulp samples are also routinely submitted to an external laboratory for check assay purposes.

All results of the QA-QC program are routinely monitored on a sample lot basis, monthly and quarterly to assess the accuracy and precision of the sampling and analytical processes.
