PRESS RELEASE September 5, 2025 Symbol: TSX-V: ATOM FSE: DO80

ATOMIC MINERALS ANNOUNCES PRIVATE PLACEMENT OF UNITS

a non-brokered private placement financing of up to 30,000,000 units (“Unit”) at $0.05 per Unit for gross proceeds of up to $1,500,000 (the “Private Placement”).

Each Unit consists of one common share and one-half of one transferable warrant. Each whole warrant (a “Warrant”) is exercisable into one common share at $0.10 per share for 1 (one) year from closing. If, following the final closing date of the Private Placement, the Company’s common shares close at or above $0.20 on the TSX Venture Exchange (“TSXV”) (or such other exchange on which the shares may trade) for ten (10) consecutive trading days, the Company may accelerate the warrant expiry date by issuing a news release. The warrants would then expire 30 days from the date of that notice.

The Private Placements may be closed in one or more tranches subject to conditional approval from the TSXV.

Subject to compliance with applicable laws and TSXV approval, the Company may pay a finder's fee or commission of up to 8% to persons who assist in the introduction of investors to the Company, which without limiting the foregoing may include cash, common shares and warrants or a combination thereof.

The gross proceeds from the issue and sale of the Units, excluding Warrant proceeds, will be used for exploration and development of the Company's projects in the USA and Saskatchewan and for general working capital purposes and accounts payable.

The securities described herein have not been, and will not be, registered under the United States Securities Act of 1933, as amended (the “U.S. Securities Act”), or any state securities laws, and accordingly may not be offered or sold within the United States except in compliance with the registration requirements of the U.S. Securities Act and applicable state securities requirements or pursuant to exemptions therefrom. This press release does not constitute an offer to sell or a solicitation to buy any securities in any jurisdiction.
