Rosa Ventures Signs Letter of Intent for Option Agreement on San Lázaro Copper Project in Chile
April 2, 2026
Rosa Ventures Ltd. is pleased to announce that it has entered into a Letter of Intent (“LOI”) with New Era Minerals Investments SpA for an exclusive option to acquire a 100% interest in the San Lázaro Porphyry Cu-Au (Mo) Project. The project is strategically located in the Upper Eocene-Oligocene porphyry belt of Northern Chile, approximately 15 km south of the world-class Collahuasi mining district.
“This LOI for the San Lázaro Project further strengthens our presence in one of the most prolific copper districts in the world,” said Ned Nadima, Chief Executive Officer of Rosa Ventures. “With its location near major operating mines and a large underexplored chargeability anomaly, San Lázaro represents an outstanding opportunity to advance a high-potential porphyry system in a proven geological setting.”
The LOI outlines a five-year option to earn 100% ownership through total option payments of USD $2,000,000 and a minimum exploration expenditure commitment of USD $5,000,000. The vendors will retain a 1.5% Net Smelter Return royalty subject to industry-standard buyback rights. Previous work on the project has identified significant copper and gold values associated with hydrothermally altered rocks within a large induced polarization anomaly, with substantial areas remaining untested.
Chile remains the world’s largest copper producer, and the Collahuasi district continues to demonstrate exceptional endowment. San Lázaro’s proximity to giant deposits such as Collahuasi, Quebrada Blanca, and Chuquicamata underscores its strong geological prospectivity at a time when secure copper supply is increasingly critical to global decarbonization efforts.
