About Aldebaran Resources Inc.

Aldebaran is a mineral exploration company that was spun out of Regulus Resources Inc. in 2018 and has the same core management team. Aldebaran acquired the Rio Grande copper-gold project located in Salta Province, Argentina from Regulus along with several other early-stage projects in Argentina. Aldebaran also has the right to earn up to an 80% interest in the Altar copper-gold project in San Juan Province, Argentina from Sibanye Stillwater. Altar hosts several large porphyry copper-gold systems with mineralization currently defined in six distinct zones. The Altar project forms part of a more regional cluster of world-class porphyry copper deposits, which includes Los Pelambres (Antofagasta Minerals), El Pachon (Glencore), and Los Azules (McEwen Mining). A total of 259 drill holes (119,052 m) have been completed at Altar between 1995 and 2020. Aldebaran's primary focus is the Altar project with a view to discovering new zones with higher-grade mineralization.
