NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

VANCOUVER, British Columbia, Aug. 20, 2026 (GLOBE NEWSWIRE) -- ExGen Resources Inc. (TSX.V: EXG; OTC: BXXRF) (“ExGen” or the “Company”) is pleased to announce that, further to its news releases dated June 9, 2026 and June 25, 2026, the TSX Venture Exchange (“TSXV”) has approved an extension and upsize for the Company to complete its private placement of up to 10,081,000 units (the "Units") at a price per Unit of $0.10 for gross proceeds of $1,081,000 (the “Upsized Offering”). ExGen intends on completing the second tranche of the Upsized Offering on or around August 21, 2026. For further details regarding the terms of the Upsized Offering, please see the Company’s news releases dated June 9, 2026 and June 25, 2026.

Further to its news release dated July 29, 2025 and issued on GlobeNewsWire, ExGen is also pleased to announce that it has amended and exercised the option (the “Option”) to earn a 100% interest in the MacRex property, a mineral property located in British Columbia, Canada. The Option was amended such that, to exercise the Option, ExGen paid $200,000 to the optionor on August 14, 2026 which satisfied all remaining cash obligations and exploration expenditures under the original option agreement as described in the July 29, 2025 news release.

The MacRex property is located in the Alberni Mining District of British Columbia approximately 20 kilometers from the city of Port Alberni. The claims are accessible via a series of logging roads reaching a significant portion of the property resulting in easy access for exploration and potential future development. The MacRex property was subject to considerable exploration going back to the 1980’s and a number of copper, gold and silver showings are recorded throughout the property. The property surrounds the Mactush property which was optioned in 2024 for approximately $625,000. The Company has reviewed reports and assessment filings on Mineral Titles and has determined this property will complement its property portfolio.

Jason Riley, Chief Executive Officer of ExGen, commented “With this last round of the financing we now have the treasury flexibility to strategically unlock the value of our properties. We are further pleased to have negotiated this amended exercise for MacRex. This amendment saves ExGen $350,000 in cash payments and the entire $1,500,000 in expenditures that were previously required over the life of the option.”
