GOLDHAVEN ANNOUNCES ADDITIONAL $700,000 CRITICAL MINERAL FLOW-THROUGH FINANCING

Goldhaven Resources Corp. intends to complete an additional non-brokered flow-through private placement financing for gross proceeds of up to $700,000 through the issuance of up to 2,641,509 flow-through shares at a price of 26.5 cents per share.

The proposed offering together with the flow-through offering completed by Goldhaven earlier in 2026 will bring total 2026 flow-through financing to approximately $2.75-million, financing the company's initial exploration and drill program at the Magno project, with potential to expand the program through the company's recently announced listed issuer financing exemption offering.

The flow-through shares will qualify as flow-through shares within the meaning of the Income Tax Act (Canada) and are expected to qualify as critical mineral flow-through shares. No warrants will be issued in connection with the offering.

The gross proceeds will be used to incur eligible Canadian exploration expenses that qualify as flow-through critical mineral mining expenditures, which the company intends to renounce to subscribers with an effective date no later than Dec. 31, 2026.

The company may pay finders' fees in connection with the offering in accordance with applicable securities laws and exchange policies. Completion of the offering is subject to customary closing conditions, including regulatory approvals. All securities issued will be subject to a statutory hold period of four months and one day.
