Increase In Mineral Resources For Rio Grande Gold-Copper Project

VANCOUVER – Aldebaran Resources Inc. and Centauri Minerals Inc. reported on the updated mineral resource estimate for the Rio Grande gold-copper project in Salta, Argentina (MRE).
Indicated Resources containing 1.45 million ounces of gold, 384,000 tonnes of copper and 12.7 million ounces of silver; 153.7 million tonnes grading 0.29 g/t gold, 0.25% copper and 2.6 g/t silver. Inferred Resources containing 1.55 million ounces of gold, 420,000 tonnes of copper and 17.8 million ounces of silver; 220.8 million tonnes grading 0.22 g/t gold, 0.19% copper and 2.5 g/t silver. Mineralization is still open in several directions, with significant porphyry potential beneath the current resource, with historical drilling hitting 257.2 m of 1.20 g/t gold, and 0.53% copper in porphyry dykes.
Sam Leung, Chief Executive Officer and Director of Centauri, said, “This new mineral resource estimate is fresh evidence that encourages modern exploration and future studies on the Rio Grande gold-copper project. With no drilling or targeting programs since 2012, Centauri now has the exciting opportunity to apply modern geophysical and geochemical tools ahead of future drilling programs on a project that already contains a substantial mineral inventory. With this resource in hand, a drill program planned for later this year and five additional exploration projects in our portfolio, Centauri is well set up to move forward to becoming a public company in the first half of 2026.”
