Aldebaran Announces Execution of Arrangement Agreement for Spin-Out of Centauri Minerals Inc.

Aldebaran Advances Altar Development Pathway and Executes Long-Awaited Centauri Spin-Out to Unlock Dual-Jurisdiction Value

By The Northwire Desk — AI Analysis Jun 01, 2026 · 07:44 ALDE · 3.14 Aldebaran Resources Inc.
Executive Summary
  • The most recent development (June 1, 2026) marks the execution of a statutory arrangement agreement to spin out the majority-owned subsidiary, Centauri Minerals Inc., to Aldebaran shareholders on a one-for-ten basis.
  • The transaction allocates approximately 18.5 million Centauri shares to Aldebaran shareholders, with Aldebaran retaining a 41.78% stake in Centauri post-distribution.
  • The spin-out separates the Rio Grande copper-gold exploration portfolio into an independent entity while Aldebaran concentrates capital and focus exclusively on its flagship Altar project.
  • A special shareholder meeting is scheduled for August 7, 2026, with regulatory, court, and TSX Venture Exchange approvals required for completion by mid-August 2026.
  • Historically, the company has systematically de-risked Altar through extensive infill drilling (converting inferred resources to measured and indicated categories) and released a highly favorable Preliminary Economic Assessment (PEA) in October 2025 projecting a $2 billion after-tax NPV and 20.5% IRR.
  • Financially, the company successfully closed approximately $45.3 million CAD in February 2026 to fully fund the upcoming Pre-Feasibility Study (PFS).
Material Impact
  • The spin-out execution is a procedural milestone rather than a disruptive event. The strategic thesis of separating the exploration-stage Rio Grande assets from the advanced Altar project was already priced in following the October 2025 formation announcement and subsequent resource updates.
  • The distribution mechanics (1-for-10) and Aldebaran's retained ~41.8% stake provide shareholders with immediate exposure to Centauri's upside in northern Argentina while preserving Aldebaran's concentrated leverage to the Altar copper-gold system.
  • The transaction is fully aligned with management's stated capital allocation strategy to unlock value through distinct project lifecycles and does not introduce unexpected risks or rewards.
