Lead-Zinc Resources in the Altiplano

altiplano_pb-zn con logo

The Mexican Altiplano mining region has the biggest endowment in Pb-Zn resources in the country, and is host to the two largest Pb-Zn ore deposits: Peñasquito and Cordero. The Altiplano has total public all- inclusive resources of 26.7 B lb Pb and 71 B lb Zn, including the two giant deposits of Peñasquito, with 6,245 M lb Pb and 14.6 B lb Zn, and Cordero, with 5,139 M lb Pb and 9,616 M lb Zn.

Pb-Zn resources occur in several mineralization styles, such as intermediate-sulphidation epithermal, Mississipi valley type (MVT), volcanogenic massive sulphide (VMS), carbonate replacement (CRD), skarn, and sedimentary exhalative (SEDEX). From the total resources outlined to date in the region, 43% of the Pb resources and 34% of the Zn resources are in the intermediate-sulphidation deposits of Goldcorp´s Peñasquito and Levon´s Cordero, making this the most relevant lead & zinc mineralization style, along with the carbonate replacement and skarn categories.

Other significant Pb-Zn deposits present in the Altiplano are Silver Standard´s Pitarrilla with 1,917 M lb Pb and 4,384 M lb Zn, followed by the Fresnillo and Saucito deposits held by Fresnillo Plc., with 2,055 M lb Pb and 4,081 M lb Zn, and 1,093 M lb Pb and 1.983 M lb Zn respectively.

Many significant carbonate replacement, skarn and intermediate-sulphidation epithermal deposits with more than 350 M lb Pb and more than 1 B lb Zn occur in the Altiplano and are widespread in the region, making the Altiplano a high-priority region to explore for additional Pb-Zn resources.

The table below shows tonnages, grades, as well as lead-zinc resources (all inclusive) for each of these deposits.

VANCOUVER, BRITISH COLUMBIA–(Marketwired – March 24, 2016) – 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.”
