Aldebaran Resources and Centauri Minerals Announce C$17 MM Brokered and Concurrent C$8 MM Non-Brokered Private Placements by Centauri

Aldebaran Resources Inc. (ALDE) announced that its majority-owned subsidiary, Centauri Minerals Inc., has launched a brokered private placement of up to 17,000,000 subscription receipts at C$1.00 per unit, aiming to raise up to C$17,000,000. A concurrent non-brokered private placement of up to 8,000,000 subscription receipts at C$1.00 per unit will raise an additional C$8,000,000. The total maximum offering size stands at C$25,000,000, which includes an agents’ option for an additional C$3,000,000.

Proceeds from the offering are designated to complete the previously announced spin-out transaction from Aldebaran and to fund exploration at Centauri’s Rio Grande project in Argentina. Gross proceeds, less 50% of the agency fee and eligible expenses, are held in escrow by Olympia Trust Company and will be released only upon the satisfaction of spin-out and TSX-V listing conditions. The spin-out arrangement requires a minimum gross raise of C$10,000,000.

Closing is expected the week of July 20, 2026. If conditions are not met by September 30, 2026, subscription receipts convert to 1.1 common shares each.

Aldebaran Resources Inc. (ALDE) announced a financing event that serves as a direct follow-up to the June 1, 2026 spin-out arrangement announcement. This transaction fulfills a prerequisite for Centauri to operate as a standalone public entity. A C$10,000,000 minimum threshold ensures the spin-out proceeds, while an escrow structure de-risks investor capital until regulatory and listing approvals are secured.

The capital injection directly funds the H2 2026 drilling program at Rio Grande, aligning with the company's stated exploration roadmap. Dilution is anticipated upon spin-out completion, but the separation of the Rio Grande and Aguas Calientes assets from the Altar project is designed to unlock distinct valuation multiples for each asset. The news is incremental and expected, providing necessary liquidity to execute the 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’s flagship Altar project hosts a 2.40 billion tonne Measured & Indicated resource grading 0.42% Cu, 0.07 g/t Au, and 1.22 g/t Ag. A 2025 Preliminary Economic Assessment (PEA) for the project outlines a 48-year mine life, a $2.0 billion after-tax net present value at an 8% discount rate, and a 20.5% internal rate of return.

The corporate restructuring separates the advanced-stage Altar project from the earlier-stage exploration portfolio, allowing each to attract tailored capital and strategic partners. This structure includes Centauri Minerals, a newly formed spin-out holding the Rio Grande, Aguas Calientes, and four greenfield projects across Salta, Jujuy, and Catamarca provinces. Rio Grande holds 1.45 moz Au and 384 kt Cu in Indicated resources.
