Aldebaran Resources and Centauri Minerals closed C$25.5M in subscription receipt financing for Centauri's spin-out, funding the Rio Grande gold-copper project in Argentina.
Aldebaran Resources and Centauri Minerals closed a C$25.5 million subscription receipt offering tied to Centauri's planned spin-out, with proceeds earmarked for the Rio Grande gold-copper project in Argentina.
The financing combined a C$17.5 million brokered tranche led by TD Securities, with ATB Cormark, Canaccord Genuity and National Bank Financial participating, plus a C$8 million non-brokered placement. Investors paid C$1 per subscription receipt.
The money sits in escrow with Olympia Trust pending conditions tied to the spin-out, which Aldebaran and Centauri announced June 1. Each receipt converts to one Centauri common share when the escrow conditions clear. If the deal does not close by Sept. 30, holders get 1.1 shares instead. If the arrangement falls apart entirely or misses a 120-day deadline, the cash goes back to investors pro rata.
The agents earned a 6% cash commission on the brokered portion. No commission was paid on the non-brokered tranche.
Centauri plans to spend the net proceeds on exploration at Rio Grande, a gold-copper project in Salta province, plus other portfolio assets and general corporate purposes.
Centauri holds a 100% interest in roughly 40,000 hectares across Salta, Jujuy and Catamarca provinces. The portfolio was spun out of Aldebaran. Rio Grande already has an NI 43-101 compliant mineral resource estimate. The company has offices in Salta and Vancouver and is currently a private entity majority-owned by Aldebaran, with plans to go public this year.
Aldebaran itself owns 80% of the Altar copper-gold project in San Juan province. Altar sits near a cluster of world-class deposits including Los Pelambres, El Pachón and Los Azules. Aldebaran published an updated resource estimate for Altar in November 2024 and a preliminary economic assessment in October 2025.
The TSX Venture Exchange still needs to approve the listing of Centauri shares issuable on conversion of the receipts.
The closing marks the latest step in Aldebaran's strategy to separate its Argentine copper assets from Centauri's earlier-stage gold-copper portfolio, giving each a distinct public vehicle and funding path.
