LIGHTHOUSE GOLD CLOSES MARIWA-SARDINE HILL GOLD PROPERTY ACQUISITION AND ANNOUNCES TERMINATION OF PRIVATE PLACEMENT

Further to its news releases dated June 15, 2026, and Oct. 20, 2026, Lighthouse Gold Inc. has received acceptance from the Canadian Securities Exchange under its previously announced definitive property option purchase agreement with 1464911 B.C. Ltd. (the vendor), pursuant to which the company holds the exclusive right to acquire a 100-per-cent interest in the Mariwa/Sardine Hill/Lower Cuyuni gold property, located within the Oko gold district in Guyana, South America.

As consideration for the acquisition, and in addition to the $100,000 (U.S.) non-refundable deposit previously paid under the letter of intent between the company and the vendor, the company has made a cash payment of $150,000 (U.S.) to the vendor, and the company has issued to the vendor 35 million common shares of the company at a deemed price of 18.5 cents per share for an aggregate deemed value of $6,475,000, representing approximately 15.98 per cent of the issued and outstanding common shares of the company calculated immediately following the acquisition. Together with the 20,000 common shares previously held by the vendor, the vendor now holds 35.02 million common shares of the company, representing approximately 15.99 per cent of the issued and outstanding common shares. In accordance with applicable securities laws and the conditions of the Canadian Securities Exchange for acceptance of the acquisition, the consideration shares are subject to restrictions on resale until the later of: (a) four months and one day from the date of issuance; and (b) 10 trading days following the filing of the company's financial statements that reflect the acquisition value, not as a subsequent event.

The property comprises three medium-scale mining permits issued under the Mining Act, 1989 (Guyana), covering an aggregate of approximately 3,240 acres in the Cuyuni-Mazaruni region of Guyana. The property is at an early exploration stage and no mineral resources or mineral reserves have been established on the property. Each permit was originally granted on Nov. 4, 2015, for a five-year term and has since been renewed by the Guyana Geology and Mines Commission (GGMC) and is currently in good standing. The company's right to acquire the property derives from the vendor's option dated July 8, 2026, to acquire the property from the arm's-length holder of record, and any transfer of the permits on exercise of that option is subject to the approval of the GGMC and/or the Minister of Natural Resources of Guyana.

The consideration for the acquisition, including the number of consideration shares, was determined through arm's-length negotiations between the company and the vendor, having regard to the stage of development of the property and the company's remaining obligations under the definitive agreement. The clarification of the results and historical work disclosed in the company's news release dated Nov. 3, 2026, was required because of an issue with the company's previous disclosure regarding the property and not because of any issue with the company's understanding of the property. Accordingly, the clarification did not change the company's determination of the consideration.

The acquisition is an arm's-length transaction, and, other than the vendor's holding of 20,000 common shares of the company prior to the acquisition, there is no relationship between the company or any of its directors, officers or insiders and the vendor or any of its directors, officers or insiders. Upon issuance of the consideration shares, the vendor became an insider of the company and the vendor and its principal will file personal information forms with the Canadian Securities Exchange.

A copy of the definitive agreement will be available under the company's profile on SEDAR+.

Termination of private placement

The company also announces that its previously announced private placement, announced on Oct. 22, 2026, and Oct. 23, 2026, has been terminated. No securities were issued and no proceeds were received under the private placement.
