Lundin Mining officially announced the initial mineral resource estimate at the Filo del Sol project, located in the Vicuña district, a region shared between the San Juan province(Argentina) and the Atacama region(Chile).
The potential mineral resources of Filo del Sol project
This operation is managed by Vicuña Corp, a 50/50 joint venture between Lundin Mining and BHP. This strategic partnership allows sharing infrastructure and maximizing synergies between the deposits, increasing operational efficiency and long-term projection.
[post_relacionado]According to the information disclosed, Vicuña concentrates 13 million tons of measured and indicated copper and 25 million tons inferred. With respect to gold, it contains 32 million ounces in M&I resources and 49 million inferred. To this is added a silver wealth of 659 million ounces M&I and 808 million ounces in the inferred category.
These figures place the district among the 10 largest in the world in copper mineral resources, with a strategic value multiplied by its polymetallic composition. At Filo del Sol , 606 Mt with 1.14% CuEq were identified, representing 4.5 Mt of copper, 9.6 Moz of gold and 259 Moz of silver. Josemaría, on the other hand, contributes 196 Mt with 0.73% CuEq, located near surface.
In addition, the oxide layer at Filo del Sol could be exploited by heap leaching, a lower initial investment technique. This area contains 434 Mt with 0.34% copper, 3.9 Moz of gold and 35 Moz of silver.
On the other hand, recent drilling in peripheral and deep zones has found continuous mineralization continuous mineralizationsuggesting an extension beyond the current resource model boundary. This indicates significant growth potential both laterally and at depth, strengthening the expectation of a world class operation.
The resource report will serve as the basis for the joint technical report between Lundin Mining and BHP, which is expected in the first quarter of 2026. This document will chart the path for the comprehensive development of the Vicuña mining complex.
The initial mineral resource has highlighted the potential for one of the world’s highest grade undeveloped open pit copper projects and one of the world’s largest gold and silver resources.
