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 a cluster of large porphyry copper-gold systems with mineralization currently defined in four distinct zones. The Altar project forms part of a larger cluster of world-class porphyry copper deposits, which includes Los Pelambres in Chile (Antofagasta Minerals), along with El Pachón (Glencore), and Los Azules (McEwen Copper) in Argentina. A total of 266 drill holes (123,968 m) have been completed at Altar between 2003 and 2021. In mid-2018 an updated NI 43-101 resource was prepared for Altar by Independent Mining Consultants Inc. based on the drilling completed up to 2017. The updated Altar NI 43-101 report is available on Aldebaran's SEDAR profile at www.sedar.com. Aldebaran’s primary focus is the Altar project with a view to discovering new zones with higher-grade mineralization.
