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

VANCOUVER, British Columbia, Dec. 24, 2025 (GLOBE NEWSWIRE) — ExGen Resources Inc. (TSX.V: EXG; OTC: BXXRF) (“ExGen” or the “Company”) is pleased to announce that it has entered into a binding letter of intent dated December 19, 2025 (“LOI”) with an arm’s length private company (“PrivateCo”) to acquire a second silver stream (“Silver Stream 2”) on a past-producing gold mine located in South America (the “Property”). This Silver Stream 2 is in addition to the first silver stream that ExGen acquired on the Property as announced in its prior news release on December 17, 2025. ExGen’s first silver stream is substantially similar to this Silver Stream 2, and doubles ExGen’s aggregate silver stream on the Property.

Under the terms of the LOI, ExGen paid US$500,000 in consideration for the acquisition of a 33.3% silver stream on the first 333,333 ounces of silver produced from the Property and a further 16.7% silver stream on any additional silver produced from the Property (the “Transaction”).

Jason Riley, Chief Executive Officer of ExGen, commented, “With two silver streams now secured, we are building a formidable foundation of potential future cash flow, strategically positioning ExGen to capitalize on silver price momentum and drive long-term value.”

THE PROPERTY
The Property is currently owned by a group of private individuals (the “Vendors”). PrivateCo is seeking to purchase the Property through an option (the “Option”) with the Vendors.

TERMS OF THE LOI
Subject to the terms and conditions of the LOI, certain terms of the Transaction are as follows:

• ExGen made a cash payment of US$500,000.
• ExGen will pay to PrivateCo a delivery price for the silver delivered pursuant to Silver Stream 2 equal to 20% of the spot silver price, as determined by a major exchange, which exchange will be determined by the parties, acting reasonably.
• Pursuant to the binding LOI, PrivateCo is required to deliver a minimum of 4,200 ounces of silver to ExGen each calendar quarter beginning with the second quarter of 2027 (the “Quarterly Minimum”). If the Quarterly Minimum is not met, the Vendor will make up any shortfall to ExGen with an equivalent value of gold.
• ExGen will have preferential rights to participate in any future streaming or royalty transactions by PrivateCo on Property.
• The parties may enter into definitive streaming agreement containing terms and conditions as set out in the LOI and any other terms and conditions as are customary for transactions of a similar nature.

CAUTIONARY STATEMENTS
There can be no assurance that the proposed Transaction will be completed as proposed or at all. In particular, there is no guarantee that PrivateCo and the Vendors will execute the Option, that the Option will be exercised by PrivateCo, that a mine on the Property will be put into production, or that production from any such mine will be sufficient to satisfy the requirements of the Quarterly Minimum, the LOI and Silver Stream 2.
