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 Limited. The

Altar project hosts multiple porphyry copper-gold deposits with potential for additional discoveries. Altar forms part
