Overview

In September 2017, the commencement of construction at Lindero was officially launched (see Fortuna news releases dated September 21, 2017 and December 21, 2017). Lindero has been designed as an 18,750 tonnes per day owner operated open pit mine with a pit life of 13 years based on existing mineral reserves. Crushed ore will be placed on a leach pad with the pregnant solution pumped to SART1 and ADR2 plants prior to electrowining and refining where gold will be poured to doré bars.

The initial capital cost budget estimate for the construction of Lindero as set out in the technical report entitled “Fortuna Silver Mines Inc.: Lindero Property, Salta Province, Argentina” dated effective October 31, 2017 is forecast to increase to US$298 million, an increase of 25 percent over what was budgeted in the technical report; this amount does not include VAT which is expected to be recovered in the first 24 months from the start of mining operations. The technical report of the Lindero Project is available on SEDAR at www.sedar.com and on the Company's website at https://fortunasilver.com/site/assets/files/4098/lindero-project-technical-report-effective-date-31-oct-2017.pdf.

Location

The Lindero Project is located in the Argentinian puna at an elevation of approximately 3,500 to 4,000 meters, 260 kilometers due west of Salta City at latitude 25° 04' 56" S and longitude 67° 46' 47" W. Drive time from Salta City to Lindero is approximately 7 to 7.5 hours over a road distance of 420 kilometers. Access to the project is via National Route 51, which passes through the towns of San Antonio de Los Cobres and Olacapato, and by Provincial Route 27, which passes through the towns of Pocitos and Tolar Grande. Tolar Grande is the nearest town to the project, located 75 kilometers to the northeast.

Geology and Mineralization

The Lindero deposit is a gold-rich porphyry system hosted within a series of diorite to monzonite porphyritic stocks that intrude coarse-grained Ordovician granites and Early Tertiary red bed sandstones. Mineralization forms an inward plunging semi-circular shape approximately 600 meters in diameter and extends to a drill tested depth of 600 meters. Gold-copper mineralization shows a strong relationship to lithology, K-feldspar alteration, and stockwork veining.
