The Company announced that it closed the second and final tranche (the “Second Tranche”) of its non-brokered private placement (the “Private Placement”).

The Company announced that it closed the Second Tranche of the Private Placement as previously announced in the Company’s news releases dated January 27, 2026 and February 19, 2026.

In connection with the Second Tranche, Gold X2 issued 58,992,945 charity flow-through common shares of the Company (each, a “Charity FT Share”) at a price of $1.233 per Charity FT Share for gross proceeds of $72,738,307. With the Second Tranche closing, the Company has raised total gross proceeds of $115,898,306 in the Private Placement.

The gross proceeds from the sale of the Charity FT Shares in the Second Tranche will be used to advance exploration and resource expansion activities at the Company’s Moss Gold Project in Thunder Bay which will qualify as “Canadian exploration expenses” and “flow-through mining expenditures”, as those terms are defined in the Income Tax Act (Canada) (the “Qualifying Expenses”). $9,450,000 in Qualifying Expenses will be incurred and renounced by Gold X2 to the subscribers of the Charity FT Shares in the Second Tranche effective as at September 15, 2026, and $63,288,300 in Qualifying Expenses will be incurred and renounced by Gold X2 to the subscribers of the Charity FT Shares in the Second Tranche effective as at December 31, 2026.

In connection with their strategic investment, AngloGold Ashanti will acquire an aggregate of 58,992,945 common shares, representing approximately 9.9% of the issued and outstanding common shares in the Company following closing of the Private Placement.

All securities issued pursuant to the Second Tranche will be subject to a statutory hold period of four months plus one day from the date of issuance, in addition to such other restrictions as may apply under applicable securities laws of jurisdictions outside Canada. No finder’s fees were paid in connection with the Second Tranche.

None of the securities sold in connection with the Second Tranche have been and will not be registered under the United States Securities Act of 1933, as amended, and no such securities may be offered or sold in the United States absent registration or an applicable exemption from the registration requirements. This news release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in the United States or any jurisdiction in which such offer, solicitation or sale would be unlawful.
