ExGen Signs Purchase Agreement to Acquire Lithium Properties in Nevada

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

VANCOUVER, British Columbia, April 30, 2026 (GLOBE NEWSWIRE) — ExGen Resources Inc. (TSX.V: EXG; OTC: BXXRF) (“ExGen” or the “Company”) is pleased to announce that, further to its news release dated October 17, 2025, the Company has signed an asset purchase agreement (the “Purchase Agreement”) dated April 29, 2026 to acquire from an arm’s length private company and its wholly owned subsidiary (the “Vendors”, and each a “Vendor”) an interest in three lithium properties in Nevada, including claims pursuant to two option agreements, and other associated assets (the “Acquisition”). The Acquisition will greatly expand ExGen’s Nevada lithium interests, presently focused on the Spark North Lithium property (the “Spark North Property”). The Spark North Property is located just north of Surge Battery Metals Inc.’s (TSXV: NILI) (“Surge Battery”) Nevada North Lithium Project, which hosts a large and high grade lithium resource (see below for more information regarding Surge Battery’s Nevada North Lithium Project). ExGen is acquiring an option to purchase certain claims comprising the Spark South lithium property (the “Spark South Property”), which is situated adjacent to the southern boundary of Surge Battery’s Nevada North Lithium Project, as well as certain other claims included in the Spark South Property.

Work completed on the Spark South Property shows that the property hosts a similar geological setting as Surge Battery’s Nevada North Lithium Project. Surge Battery and its joint venture partner have “commenced an advanced metallurgical optimization program with Kemetco Research Inc. to support the continuing prefeasibility study (PFS) for the company’s flagship, high-grade Nevada North lithium project (NNLP) located in Elko county, Nevada” (Surge Battery News Release dated April 1, 2026).

In addition, pursuant to the Purchase Agreement, ExGen will also acquire options to purchase two additional properties providing exposure to two other prospective lithium districts in Nevada. Upon the closing of the Acquisition (the “Closing”), ExGen will have a significant stake in the lithium industry in Nevada, which bills itself as the Lithium Capital of North America¹. The lithium industry in Nevada now runs a broad spectrum of the electric vehicle supply chain from mining through to battery and electric vehicle production.

ExGen management has noticed that lithium in Nevada has attracted a great deal of investor attention over the past year, centered on Lithium Americas Corp.’s (“Lithium Americas”) Thacker Pass project, now in development, located in Humboldt County, Nevada, part of the McDermitt Caldera, approximately 282 km due west from the Spark North Property and Spark South Property. Lithium Americas’ Thacker Pass Project will receive more than US$3.10 billion in funding from the US Department of Energy², General Motors³, and Orion Resource Partners⁴.

THE PURCHASE AGREEMENT
The Purchase Agreement contemplates the Acquisition of the Vendors’ legal and beneficial interest in: (a) the Spark South Property in Elko County, Nevada, consisting of 297 claims, either through the purchase of an option or through direct purchase of the claims from the Vendors (the “Spark South Lithium Project”); (b) an option to purchase the Libra lithium project in Esmeralda County, Nevada consisting of 107 claims (the “Libra Lithium Project”); (c) an option to purchase the Augusta lithium project in Churchill County, Nevada consisting of 32 claims (the “Augusta Lithium Project”, and together with the Spark South Lithium Project, the Libra Lithium Project, and the Augusta Lithium Project, the “Projects”); (d) a 1.5% net smelter returns royalty on all mineral production from 111 claims located in Elko County, Nevada previously granted by ExGen to a Vendor (the “NSR”); and (e) with the exception of any cash or cash equivalents owned by one of the Vendors (including, for greater certainty, any common shares in the capital of ExGen (“ExGen Shares”)), any and all other property and assets owned or asserted by the Vendors (the “Other Property and Assets”, and together with the Projects and the NSR, the “Assets”). As mentioned above, certain of the claims comprising the Spark South Lithium Project, and the claims comprising the Libra Lithium Project and the Augusta Lithium Project, are held by a Vendor pursuant to option agreements (the “Option Agreements”) with a third party. ExGen will acquire the rights and obligations of such Vendor under the Option Agreements at the Closing.

THE SPARK SOUTH LITHIUM PROJECT
The Spark South Lithium Project is adjacent to the southern boundary of Surge Battery’s Nevada North Lithium Project in Elko County, Nevada. In a news release dated September 24, 2024, Surge Battery announced that the Nevada North Lithium Project had the highest grade lithium clay deposit in the USA (11.24 Mt LCE grading 3,010 ppm Li at a 1,250 ppm cutoff). The technical report for Surge Battery’s Nevada North Lithium Project was prepared for Surge Battery by authors Jeffrey D. Phinisey of TAG Resources LLC and Bruce M. Davis, independent geostatistical consultant, titled “Technical Report on Mineral Resource Estimate for the Nevada North Lithium Project, Elko County, Nevada USA” and dated effective October 9, 2024.

The Vendors’ Spark South Lithium Project is adjacent to the southern boundary of Surge Battery’s Nevada North Lithium Project in Elko County, Nevada. On June 9, 2025, Surge Battery announced the results of a NI 43-101 Technical Report Preliminary Economic Assessment (the “Surge Battery PEA”), highlighting an after-tax NPV (8%) of US$9.21 Billion⁵. The Surge Battery PEA was jointly by lead consultants M3 Engineering & Technology Corp. and Independent Mining Consultants, titled “Nevada North Lithium Project – NI 43-101 Thechical Report – Preliminary Economic Assessment – Elko County, Nevada” and dated effective May 19, 2025. Surge Battery is now conducting metallurgical testwork in support of a prefeasibility study⁶.

ExGen cautions that past results or discoveries on properties in proximity to ExGen’s properties, including Surge Battery’s Nevada North Lithium Project, may not necessarily be indicative of the presence of mineralization on any of the Projects.

Jason Riley, Chief Executive Officer of ExGen, commented, “ExGen’s long-held conviction in the Elko County lithium district is being validated by the extraordinary progress on our doorstep. Since our initial acquisition of the Spark North property in early 2025, our neighbor, Surge Battery Metals, has confirmed the world-class scale of this region. Their recent Preliminary Economic Assessment—outlining an 11.2 million tonne LCE resource with a US$9.17 billion after-tax NPV—formally establishes Elko County as a premier lithium jurisdiction in North America.”

“Surge has subsequently secured Evolution Mining as their JV partner and begun work advanced metallurgical testing to support the delivery of a Pre-Feasibility Study to evaluate the project’s development potential. We look forward to the numerous catalysts in the district over the course of this year as we advance our own assets to unlock value for ExGen.”

In order to acquire a 100% undivided interest in and to the Spark South Lithium Project and the Libra Lithium Project, ExGen will be required to (a) pay the third party optionor of the two properties an aggregate of US$225,000 in cash in annual tranches of US$75,000 beginning on January 21, 2027, and (b) incur cumulative qualifying exploration expenditures on the two properties of at least US$1,450,000, US$450,000 of which must be incurred by January 21, 2028 with the balance of US$1,000,000 incurred by January 21, 2029. In addition, the Company may be obligated to pay the third party optionor of the two properties up to US$8,000,000 in cash in the event that ExGen (i) exercises the option, (ii) has received title to each of the Spark South Lithium Project and the Libra Lithium Project, and (iii) has received an independent technical report on the applicable Project that indicates a mineral resource of not less than 2,000,000 tonnes of lithium with a grade of 1,500 ppm on such Project. For clarity, the foregoing obligation applies separately to and burdens each of the Spark South Lithium Project and the Libra Lithium Project, but in no event shall exceed $4,000,000 for a single Project or $8,000,000 in total for both Projects.

In order to acquire a 100% undivided interest in and to the Augusta Lithium Project, ExGen is only required to pay the third party optionor $30,000 in cash on or before May 12, 2026. There are no work commitments associated with the exercise of this option.
