Lindero is an open pit, heap leach gold project with a completed feasibility study that has been granted all environmental and other major permits necessary for development. In September 2017, the Company announced a positive construction decision for Lindero with commissioning expected in the second quarter of 2019 (see Fortuna news release dated September 21, 2017). Lindero has been designed as an 18,750 tpd1 owner operated open pit mine with a pit life of 13 years based on existing reserves. Crushed ore will be placed on a leach pad with the pregnant solution pumped to SART2 and ADR3 plants prior to electrowining and refining where gold will be poured to doré bars.

Adsorption, Desorption and Recovery
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.
