Aldebaran Announces Collaboration Agreement with Nuton LLC, a Rio Tinto Venture

VANCOUVER, January 15, 2024 - Aldebaran Resources Inc. ("Aldebaran" or the "Company") (TSXV:ALDE),(OTCQX:ADBRF) is pleased to announce that it has entered into a collaboration agreement with Nuton LLC, a Rio Tinto Venture ("Nuton") to evaluate the use of Nuton's proprietary primary sulphide leaching technologies on the Altar copper-gold project, located in San Juan, Argentina.

Under the terms of the agreement, Aldebaran will deliver samples representing various styles of mineralization from the Altar project to Nuton. Nuton will then complete detailed mineralogical analyses of each sample before placing the material into columns. Samples will be placed in columns with a height of 1 m, each under different controlled Nuton operating conditions. It is expected that the full results will be available approximately one year after the columns are loaded. Test work is currently anticipated to commence in H1 2024.

As part of the agreement, Aldebaran has granted exclusivity to Nuton in the area of novel, patented or trade secret leaching technologies, for a period of one year starting on the agreement date of January 9, 2024. The parties will share the cost of the test program with Aldebaran covering the cost of preparation and shipping of the samples to Nuton, and Nuton paying for the costs of metallurgical test work.

John E. Black, Chief Executive Officer of Aldebaran, commented: "We're happy to collaborate with Nuton to evaluate the potential use of their sulphide leaching technology at the Altar project. While sulphide leaching isn't necessary to move the Altar project forward, it could positively impact the project's economics, if successful."

Adam Burley, Chief Executive Officer of Nuton, commented "We are pleased to announce this collaboration agreement with Aldebaran. Nuton has a wide range of potential use cases. At Altar we are encouraged by the potential of Nuton to unlock copper resources in a project with substantial scale potential and in a way that is more environmentally efficient than conventional processes"

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 holds a 60% interest in the Altar copper-gold project in San Juan Province, Argentina and can earn an additional 20% interest in the project by completing a further US$25 million in expenditures at Altar over the next three years. The Altar project hosts multiple porphyry copper-gold deposits with potential for additional discoveries. Altar forms part of a cluster of world-class porphyry copper deposits which includes Los Pelambres (Antofagasta Minerals), El Pachón (Glencore), and Los Azules (McEwen Copper). In March 2021 the Company announced an updated mineral resource estimate for Altar, prepared by Independent Mining Consultants Inc. and based on the drilling completed up to and including 2020 (independent technical report prepared by Independent Mining Consultants Inc., Tucson, Arizona, titled "Technical Report, Estimated Mineral Resources, Altar Project, San Juan Province, Argentina", dated March 22, 2021 - see news release dated March 22, 2021).
