So this discovery is not just a mining story, it is a climate and security story that runs straight into environmental law.<\/p>\n\n\n\nA deposit big enough to change the math<\/h2>\n\n\n\n
In a 2025 news release, Lundin Mining reported an initial resource estimate that includes 14.3 million tons of copper measured and indicated and 27.5 million tons inferred across Filo del Sol and Josemar\u00eda. <\/p>\n\n\n\n
The same release lists 32 million ounces of gold measured and indicated and 659 million ounces of silver measured and indicated, with additional inferred metal beyond that. It is the kind of inventory that can pull in big money fast, especially when copper is treated as a bottleneck for electrification.<\/p>\n\n\n\n
A newer integrated technical study released in February 2026 lays out a staged development plan that starts with a sulphide mill at Josemar\u00eda, then adds leaching and later expansion tied to Filo del Sol. <\/p>\n\n\n\n
Lundin says the concept targets about 435,000 tons of copper a year on average over the first 25 full years and a mine life above 70 years, with later stage infrastructure that includes a desalination plant<\/a> and pipeline. The company also stresses that this is a preliminary economic assessment, so it is a direction of travel rather than a finished business case.<\/p>\n\n\n\nCopper is now tied to energy and defense<\/h2>\n\n\n\n
