Aldebaran Resources and Centauri Minerals Announce Shareholder Approval and Receipt of Final Order for Spin-Out of Centauri Minerals

Aldebaran Resources Inc. (ALDE) shareholders approved the statutory plan of arrangement to spin out its majority-owned subsidiary, Centauri Minerals Inc., on August 7, 2026. The Court of King’s Bench of Alberta granted the final order for the Arrangement on August 11, 2026, clearing the last regulatory hurdle.

The transaction distributes approximately 18,535,783 Centauri common shares to Aldebaran shareholders on a one-for-ten basis. Completion is expected before the end of August 2026, pending standard closing conditions including TSX Venture Exchange listing approval for Centauri.

Centauri will operate as a standalone public entity holding a 100% interest in ~40,000 hectares across Salta, Jujuy, and Catamarca, Argentina, with the Rio Grande gold-copper project as its flagship. Upon completion, Aldebaran will focus exclusively on advancing its flagship Altar copper-gold project in San Juan Province.

Aldebaran Resources Inc. (ALDE) has completed the final administrative and regulatory step in a transaction initially announced on June 1, 2026. The market was fully aware of the spin-out structure, the one-for-ten distribution ratio, and the expected timeline. The news is expected, incremental, and confirms the successful execution of a previously disclosed corporate restructuring.

Aldebaran Resources Inc. (ALDE) is a pre-revenue junior explorer focused on the Altar copper-gold project in San Juan, Argentina. The company holds an 80% interest in Altar, with Sibanye-Stillwater holding the remaining 20% as a joint venture partner. The Altar project features a 2025 Preliminary Economic Assessment (PEA) projecting a 48-year mine life, $2.0 billion after-tax NPV (8%), and a 20.5% IRR.

Centauri Minerals, the newly spun-out entity, holds a portfolio of six exploration projects in northern Argentina, including the advanced Rio Grande project and the high-grade Aguas Calientes project.
