ALDEBARAN RESOURCES AND CENTAURI MINERALS ANNOUNCE CLOSING OF $25 MILLION SUBSCRIPTION RECEIPT FINANCING IN CONNECTION WITH CENTAURI SPIN-OUT

Aldebaran Resources Inc. and its majority-owned subsidiary Centauri Minerals Inc. have closed Centauri's offering of subscription receipts at a price of $1.00 per subscription receipt for aggregate gross proceeds of $25,486,000 consisting of: (i) a brokered private placement of 17,486,000 subscription receipts at the issue price, for aggregate gross proceeds of $17,486,000 completed through a syndicate of agents led by TD Securities Inc. (TDSI), as lead agent and sole bookrunner and including ATB Cormark Capital Markets, Canaccord Genuity Corp. and National Bank financial Inc.; and (ii) a non-brokered private placement of eight million subscription receipts at the issue price for gross proceeds of $8-million.

The gross proceeds of the offering, less 50 per cent of the agents' commission in respect of the brokered offering and certain eligible expenses of the agents covered by Centauri, have been deposited in escrow pursuant to the terms of a subscription receipt agreement dated July 22, 2026, among Centauri, TDSI and Olympia Trust Company, as the subscription receipt agent. The escrowed funds will be held in escrow pending satisfaction of all of the escrow release conditions, including among other things, that all conditions precedent to the completion of the arrangement (as defined below) have been satisfied, or waived with the consent of TDSI, and that there have been no material amendments to the terms and conditions of the arrangement agreement governing the terms of the arrangement which have not been approved by TDSI, acting reasonably. It is a condition to the completion of the arrangement that the offering be completed, as well as that the common shares (as defined below), including the common shares issuable on exchange of the subscription receipts, shall have been approved for listing on the TSX Venture Exchange.

Each subscription receipt will be deemed to be automatically exchanged for one freely tradeable common share in the capital of Centauri, without payment of additional consideration or further action by the holder thereof on the date that each of the escrow release conditions are satisfied or waived; provided, however, that if the escrow release conditions are not met on or before Sept. 30, 2026, each subscription receipt will entitle the holder thereof to receive 1.1 common shares.

If (i) the escrow release conditions are not satisfied on or before the date that is 120 days from the date hereof or such later date as may be agreed to by not less than 66.67 per cent of the holders of subscription receipts or, (ii) if prior to the escrow deadline, the spinout transaction previously announced by the companies on June 1, 2026, is terminated or Centauri has advised the subscription receipt agent and TDSI, or announced to the public, that the arrangement will not be completed, within five business days following the termination date, the escrowed funds shall be returned to the holders of subscription receipts pro rata.

In consideration of their services, Centauri agreed to pay the agents a cash commission in an amount equal to 6 per cent of the aggregate gross proceeds from the sale of the subscription receipts under the brokered offering. No commission was payable by Centauri in connection with the non-brokered offering.

Centauri intends to use the net proceeds from the offering to advance exploration of the Rio Grande gold-copper project located in Salta, Argentina, for the exploration and advancement of other portfolio assets, and for general corporate purposes.
