NOBLE PLAINS CLOSES $1,009,600 NON-BROKERED PRIVATE PLACEMENT

Noble Plains Uranium Corp. has closed the non-brokered private placement, previously announced on May 20, 2026. The company issued 10,096,000 units at a price of 10 cents per unit for gross proceeds of $1,009,600.

Existing shareholder Ur-Energy Inc., a leading U.S. uranium producer, participated in the offering to maintain its pro rata ownership position in the company. Ur-Energy, which holds approximately 6.14 per cent of the issued and outstanding common shares of the company, subscribed for 616,000 units for gross proceeds of $61,600. The continued support and participation of Ur-Energy, an established in situ recovery operator in Wyoming, represents a strong vote of confidence in Noble Plains' asset base and strategy.

"The ongoing commitment of our existing shareholders, together with the participation of new investors, reflects a shared conviction in the quality of our Wyoming ISR projects as the United States works to unlock a robust domestic nuclear fuel supply chain and secure energy independence," said Drew Zimmerman, chief executive officer of Noble Plains.

Each unit comprises one common share of the company and one-half of one common share purchase warrant. Each whole warrant will entitle the holder to acquire one additional share at a price of 15 cents per share for a period of two years from the date of issuance. The warrants are subject to an accelerated expiry provision such that if, at any time following the date that is 61 days after the closing date of the offering, the closing price of the common shares on the TSX Venture Exchange or such other market on which the common Shares may trade from time to time is at or above 30 cents for 10 consecutive trading days, the company may accelerate the expiry date of the warrants by issuing a news release announcing the accelerated expiry date. In such event, the warrants will expire on the fifth day following the date of such news release. Holders may exercise their warrants during the period between the date of the news release and the accelerated expiry date.

In connection with the offering, the company paid cash finders' fees of $10,600 and issued 91,000 non-transferable finders' warrants, each exercisable to acquire one share at a price of 15 cents until June 25, 2028.

The company expects to use the proceeds of the offering to carry out exploration work on the company's Duck Creek and Shirley Central uranium projects, located in the prolific Powder River basin and past-producing Shirley basin of Wyoming, as well as for general working capital purposes.

Certain directors and officers of the company participated in the offering, purchasing 600,000 units for gross proceeds of $60,000. Participation by the insiders in the offering is considered a related party transaction pursuant to Multilateral Instrument 61-101, Protection of Minority Security Holders in Special Transactions. The company is exempt from the requirements to obtain a formal valuation and minority shareholder approval in connection with the insider's participation in the offering, in reliance of sections 5.5(a) and 5.7(a) of MI 61-101, respectively, on the basis that participation in the offering by the insider did not exceed 25 per cent of the fair market value of the company's market capitalization. The company did not file a material change report in respect of the related party transaction at least 21 days before the closing of the offering, which the company deems reasonable in the circumstances as the details of the participation by insiders of the company were not settled until shortly prior to closing of the offering and the company wished to complete the offering in an expeditious manner.

All securities issued under the offering are subject to a hold period expiring Oct. 26, 2026, in accordance with applicable securities laws and the policies of the TSX Venture Exchange. The offering remains subject to final approval of the TSX Venture Exchange.
