EXGEN SIGNS BINDING LOI TO ACQUIRE SILVER STREAM ON PAST-PRODUCING GOLD

MINE

VANCOUVER, British Columbia, December 17, 2025 -- 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 15, 2025 (“LOI”) with an arm’s length private company (the “PrivateCo”) to acquire a silver

stream (the “Silver Stream”) on a past-producing gold mine located in Chile (the “Property”).

Under the terms of the LOI, ExGen paid US$500,000 in consideration for the acquisition of a 33.4% Silver

Stream until 333,334 ounces of silver have been delivered to ExGen and then a 16.7% Silver Stream on any

further silver produced from the Property (the “Transaction”).

Jason Riley, Chief Executive Officer of ExGen, commented, “ExGen has been evaluating various potential

streaming and royalty deals and we are excited to have signed our first silver stream with this LOI.”

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, and ExGen’s payment was made on

behalf of PrivateCo directly to the Vendors (as per the requirements of the LOI).

TERMS OF THE LOI

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

 ExGen has provided a cash payment of US$500,000 to the Vendors on behalf of PrivateCo.

 ExGen will pay to PrivateCo a delivery price for the silver delivered pursuant to the Silver Stream 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 the 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 the Silver Stream.
