Tesoro Gold Unveils Robust New Scoping Study for El Zorro Gold Project in Chile, Targeting 1.26 Million Ounces Over 15 Years
Tesoro Gold Ltd. has unveiled updated figures for its El Zorro gold project in Chile, highlighting robust potential and strong economic viability. The project centers on the Ternera deposit, which is slated to underpin an open-pit mining operation with a planned processing capacity of 3 million tonnes per year. Current resource estimates point to a total of 1.26 million ounces of gold over a projected 15-year mine life. Metallurgical tests conducted in Western Australia have demonstrated consistently high gold recoveries with low reagent consumption. The project will use seawater from a nearby desalination plant, offering an important advantage in the arid region. Tesoro Gold plans to use the proven Carbon-in-Pulp (CIP) process, targeting gold recoveries above 94%. Pre-production costs are estimated at USD 248 million, including USD 41 million for waste movement. In addition to developing the main Ternera pit, Tesoro is actively assessing the integration of further resources, underground options, and new exploration targets to expand the project's footprint. A pre-feasibility study is expected to be completed by the second quarter of 2026.
