Aldebaran Resources Inc.

Aldebaran Resources Inc. is a Canadian mineral exploration company focused on the acquisition, exploration, and evaluation of mineral properties, primarily copper and gold. The company's headquarters are located in Vancouver, British Columbia, Canada. Its core mission revolves around advancing the Altar copper-gold project in San Juan Province, Argentina, which is recognized as one of the world's largest undeveloped copper deposits.

The company's primary asset is the Altar copper-gold project in San Juan Province, Argentina, which hosts multiple porphyry copper-gold deposits. This project is situated within a region known for world-class porphyry copper deposits. Aldebaran previously held other exploration projects in northern Argentina, including Rio Grande and Aguas Calientes, but these were recently spun out into a new entity, Centauri Minerals Inc., to allow Aldebaran to concentrate solely on the Altar project.

John Black serves as the Chief Executive Officer and Director, having been appointed in June 2018. In late 2025 and early 2026, Aldebaran completed financings that fully funded the Altar project through its pre-feasibility study, anticipated by the end of 2026. An updated mineral resource estimate for Altar in November 2024 revealed a significant increase in measured and indicated resources, solidifying its position as one of the largest undeveloped copper-gold deposits globally. Aldebaran holds an 80% interest in the Altar project, with the remaining 20% held by Sibanye-Stillwater.
