Lundin Mining Unveils Major Resource Estimate at Filo del Sol

A Breakthrough in Global Copper, Gold, and Silver Exploration

Lundin Mining has reported its first Mineral Resource estimate for the Filo del Sol sulphide deposit. This milestone confirms the site as one of the largest greenfield copper discoveries in recent decades.

The estimate includes updates to the oxide deposit at Filo del Sol and the nearby Josemaria project. Both assets are part of the Vicuña joint venture between Lundin Mining and BHP.

Together, these deposits significantly boost the Vicuña District’s copper, gold, and silver potential. SuperMetalPrice notes that this resource ranks among the world’s top copper projects by size.

High-Grade Zones Support Early Mining and Growth Potential

The Filo del Sol deposit contains 13 million tonnes (Mt) of copper in Measured and Indicated (M&I) resources. It also holds 25 Mt in the Inferred category.

Gold and silver resources are equally impressive. The site includes 32 million ounces (Moz) of gold and 659 Moz of silver in M&I. The Inferred category adds another 49 Moz of gold and 808 Moz of silver.

High-grade sulphide mineralization at Filo del Sol includes 606 Mt at 1.14% CuEq. This core zone contains 4.5 Mt of copper, 9.6 Moz of gold, and 259 Moz of silver.

Josemaria’s near-surface high-grade zone adds 196 Mt at 0.73% CuEq. It holds 978,000 tonnes of copper, 2.4 Moz of gold, and 11 Moz of silver.

Surface oxide resources also offer strong development potential. The project includes 434 Mt at 0.34% copper, suitable for low-cost heap leaching. A high-grade oxide core adds 181 Mt at 1.05% CuEq.

Expansion Drilling and Strategic Outlook

Drilling confirms that Filo del Sol remains open at depth. The Flamenco zone, 2 kilometers south, has mineralization beyond the current pit shell.

These findings point to strong expansion potential. Lundin Mining expects continued growth in the Vicuña resource base.

CEO Jack Lundin stated the company aims to finalize a technical report by Q1 2026. This report will outline the integrated development plan for the combined assets.

SuperMetalPrice highlights this update as a key step toward building a globally ranked copper, gold, and silver complex.
