APPIA ANNOUNCES FINAL CLOSING OF ITS NON-BROKERED PRIVATE PLACEMENT

Further to the press releases of June 17, 2025, and June 24, 2025, Appia Rare Earths & Uranium Corp. has closed the final tranche of an upsized and fully subscribed non-brokered private placement of 12.5 million working capital units of the company at a price of eight cents per WC unit for $1-million. On June 24, 2025, it placed 2,428,947 flow-through units at a price of 9.5 cents per FT unit for $230,749.97. The company raised gross proceeds of $1,230,749.97.

The company closed the final tranche of the WC offering on June 27, 2025, with subscriptions for 1,706,250 WC units for gross proceeds of $136,500.

Each WC unit consists of one common share of the company priced at eight cents per common share and one common share purchase warrant. Each WC warrant entitles the holder to purchase one common share at a price of 15 cents until the earlier of: (i) two years from the closing of the offering; and (ii) in the event that the closing price of the common shares on the Canadian Securities Exchange is at least 25 cents for 10 consecutive trading days and the 10th trading day is at least four months from the closing, the date which is 30 days from the final trading day.

Each FT unit consists of one flow-through common share priced at 9.5 cents per FT share and one common share purchase warrant with each warrant entitling the holder to acquire one common share of the company at a price of 15 cents until the earlier of: (i) two years from closing; and (ii) the trigger date.

Proceeds from the WC offering will be used for general working capital and financing for exploration of the company's PCH project in Brazil. The securities issued are subject to a hold period expiring on Oct. 28, 2025.

The gross proceeds from the sale of FT units will be used for Canadian exploration expenses (within the meaning of the Income Tax Act (Canada)), which qualify as a flow-through critical mineral mining expenditure for purposes of the tax act related to the exploration program of the company to be conducted on the company's properties located in Saskatchewan. The company will renounce such Canadian exploration expenses with an effective date of no later than Dec. 31, 2025. The Canadian exploration expenses to be renounced by the company will qualify for the critical mineral exploration tax credit under the tax act.
