Fortuna Updates Reserves and Resources
(firmenpresse) - VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 03/24/16 -- Fortuna Silver Mines, Inc. (NYSE: FSM)(TSX: FVI) is pleased to report updated Mineral Reserve and Mineral Resource estimates as of December 31, 2015 for the Caylloma Mine located in Arequipa, Peru and for the San Jose Mine located in Oaxaca, Mexico.
Jorge A. Ganoza, President and CEO, commented: "Our combined Proven and Probable Reserves have been negatively impacted by a forty-one percent net decrease in silver ounces at our Caylloma mine; primarily as a result of updating geologic models, depletion, changes in commercial terms, and applying a higher cutoff and dilution to narrow silver rich veins. At San Jose, silver and gold reserves are essentially flat with respect to 2014, after successfully replacing the depletion of 4.9 million silver ounces and 38,500 gold ounces for the year."
Highlights of Reserve and Resource Update
Notes:
San Jose Mine, Mexico
As of December 31, 2015, the San Jose Mine has Proven and Probable Mineral Reserves of 3.8 Mt containing 28.2 Moz of silver and 210 koz of gold, in addition to Inferred Resources of 6.6 Mt containing a further 55 Moz of silver and 340 koz of gold.
Year-over-year, Mineral Reserves remained constant in tonnes and in contained silver and decreased 4 percent in contained gold after net changes resulting from production-related depletion and upgrades of new reserves through infill drilling . Silver grades remained essentially flat at 232 g/t and gold grades decreased 5 percent to 1.73 g/t.
Infill drilling was successful in upgrading from Inferred Resources to new Mineral Reserves approximately 1.2 Mt averaging 277 g/t Ag and 1.93 g/t Au reported for the Stockwork, Bonanza, and Trinidad veins.
Measured and Indicated Resources exclusive of Mineral Reserves decreased 15 percent year-over-year to approximately 0.8 Mt due to improved conversion of resources to reserves.
Year-over-year, Inferred Resources decreased 7 percent and 15 percent in contained silver and gold ounces, respectively. Silver grade remained flat and gold grade decreased by 8 percent. The net variation is primarily explained by additions through exploration offset by reductions from upgrading of Inferred Resources by infill drilling in the Trinidad North and Central Stockwork zones and geological reinterpretation of previously modeled veins.
Brownfields exploration budget for 2016 at San Jose is $8.2 million, which includes 22,000 meters of diamond drilling and the development of a 1,500 meter underground exploration drift that will allow better access to test the northern extension of the Trinidad North vein system. Exploration drilling is in progress at the Trinidad Central zone in the San Jose Mine and at the La Noria/San Antonio vein system, a parallel vein system located two kilometers to the west of the San Jose Mine area. The company disclosed further details of San Jose's brownfields exploration program on December 16, 2015 (refer to "").
Caylloma Mine, Peru
As of December 31, 2015, the Caylloma Mine has Proven and Probable Mineral Reserves of 2.0 Mt containing 7.7 Moz of silver and 19.3 koz of gold, in addition to Inferred Resources of 3.4 Mt containing 14.3 Moz of silver and 64.7 koz of gold.
Mineral Reserves decreased 41 percent in contained silver ounces compared to 2014. The loss of ounces is explained primarily by the update of geological models from June 2014, the net loss to mining related depletion, higher cutoff and dilution applied to narrow veins, and changes to commercial terms. The loss in reserve tonnage is lower than the silver loss, at 35 percent due to the gain in base metal credits from additions to reserves from base metal rich zones. Silver grade decreased 9 percent to 121 g/t, lead grade increased 26 percent to 2.83 %, and zinc grade increased 13 percent to 3.55 %.
Year-over-year, Measured and Indicated Resources, exclusive of Mineral Reserves, increased by 9 percent to 1.9 Mt due to the negative impact on reserves of commercial terms and the geological reinterpretation of the ore deposit.
Inferred Resources decreased by 0.96 Mt or 22 percent to 3.4 Mt, silver grades remained flat, and lead and zinc grades increased by 11 percent and 4 percent, respectively. The decrease in Inferred Resources is primarily due to the upgrading of resources through infill drilling, and changes in the geological interpretation of the mineralized zones.
Brownfields exploration budget for 2016 at the Caylloma Mine is $2.9 million, which includes 17,000 meters of diamond drilling. Drilling will be focused on testing new exploration targets in the northern portion of the Caylloma District and in the Pisacca prospect area located a short distance to the southwest of the plant as well as further exploring the northeastern extension of the Animas Vein.

Cautionary Note to United States Investors Concerning Estimates of Reserves and Resources
Reserve and resource estimates included in this news release have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for public disclosure by a Canadian company of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission ("SEC"), and reserve and resource information contained in this news release may not be comparable to similar information disclosed by U.S. companies. In particular, the term "resource" does not equate to the term "reserves". Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.
The SEC's disclosure standards normally do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by U.S. standards in documents filed with the SEC. You are cautioned not to assume that resources will ever be converted into reserves. You should also understand that "inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. You should also not assume that all or any part of an "inferred mineral resource" will ever be upgraded to a higher category. Under Canadian rules, estimated "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases. You are cautioned not to assume that all or any part of an "inferred mineral resource" exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in-place tonnage and grade without reference to unit measures. The requirements of NI 43-101 for identification of "reserves" are also not the same as those of the SEC, and reserves reported in compliance with NI 43-101 may not qualify as "reserves" under SEC standards. Accordingly, information concerning mineral deposits set forth in this news release may not be comparable with information made public by companies that report in accordance with U.S. standards.
