ALDEBARAN ANNOUNCES COMMENCEMENT OF 2023-2024 DRILL PROGRAM AT ALTAR

Aldebaran Resources Inc. has commenced drilling at the Altar copper-gold project for the 2023-2024 field season. The company currently has four active drill rigs on the property and is targeting 15,000 to 20,000 metres of drilling to be completed during the current field season. The drill program is fully funded and the company currently has approximately $25-million cash on hand.

John E. Black, chief executive officer of Aldebaran, commented: "The results of the 2022-2023 field season corroborated our idea that additional mineralization occurs between the Altar Central and Altar East mineralized centres, with the discovery of Altar United that appears to connect Altar Central and East together into a very large mineralized system. The current resource we have in hand, in addition to successful drilling from previous seasons, indicates that Altar is one of the largest undeveloped copper-gold projects in the world. The goal of the 2023-2024 drill program is to continue drilling 200 m stepouts to demonstrate the full extent of mineralization at Altar, which will contribute to an updated resource estimate for the entire project planned in H2 2024."

The 2023-2024 drill program will continue to target the 3-D DCIP/resistivity and MT geophysical anomaly (see news release dated June 13, 2022) that was the focus of the 2022-2023 drill program. As well, holes will be dedicated to continuing to expand the newly discovered Altar United zone, a higher-grade northwest-southeast trend which sits within the geophysical anomaly. Where possible, holes are also being designed to test areas within the current 2021 conceptual resource pit shell that were categorized as undefined waste due to no drilling. Several of these undefined waste areas have nearby mineralized drill holes that show that the mineralization is not closed-off; and favourable geophysical and/or geochemical anomalies occurring within, or near, the current pit shell, which offers the opportunity to convert waste material to mineralization.

The first four holes of the campaign will focus on areas immediately to the south of Altar United. Three of the first four drill holes are deepening of historic holes on the Altar property. Hole ALD-23-162EXT is an extension of a hole drilled in 2012 that was terminated at a depth of 522.70 metres. Hole ALD-23-166EXT is an extension of a hole drilled in 2012 that was terminated at a depth of 401.00 m depth. Hole ALD-23-194EXT is an extension of a hole completed in 2013 that was terminated at a depth of 530.00 m. All three of these drill holes are 200 m stepouts to test for the southern extension of mineralization discovered at Altar United. Hole ALD-23-234 is a new hole that is being drilled from surface and will test an area of undefined waste within the current 2021 conceptual pit shell.

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-per-cent interest in the Altar copper-gold project in San Juan province, Argentina, and can earn an additional 20-per-cent interest in the project by completing a further $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 Pachon (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).
