RIVERSIDE RESOURCES COMPLETES FIRST FINANCING FOR RAVENA RESOURCES CORP. IN ADVANCE OF PROPOSED TSX VENTURE SPINOUT

Riverside Resources Inc. has completed an internal reorganization of its subsidiary, formerly named RRI Holdings Ltd. and renamed Ravena Resources Corp., and Ravena has completed an initial founder financing. The reorganization and founder financing are the first steps in Riverside's plan to spin out its portfolio of gold-silver and copper-gold exploration projects in Sonora, Mexico, into a separately listed company on the TSX Venture Exchange, a process that could occur following additional financing and shareholder approval, consistent with Riverside's approach with Capitan Silver and Blue Jay Gold over the past several years.

"The creation of Ravena follows the same disciplined spinout model that Riverside has used to launch quality companies such as Capitan Silver and Blue Jay Gold, and allows our Mexican exploration portfolio to be advanced by a dedicated team and balance sheet while Riverside retains meaningful long-term exposure through its share position and a portfolio of net smelter return royalties," said Dr. John-Mark Staude, president and chief executive officer of Riverside. "Ravena will be led by an experienced public company team and is anchored by the drill-ready, past-producing Los Cuarentas gold-silver project, supported by Riverside's technical network of more than 30 years in Mexico. I am excited to be the chairman of Ravena and will maintain active in the next growth steps."

The reorganization

Prior to the reorganization, Ravena was a wholly owned subsidiary of Riverside that holds, indirectly through its Mexican subsidiary RRM Exploraciones SAPI de CV, a portfolio of five exploration projects located in Sonora, Mexico: Los Cuarentas (flagship), Cecilia, Ariel, El Valle and Suaqui Grande. Maps and descriptions of these properties are available on Riverside's website. Over the past decade, the properties have received exploration financing from major companies including BHP, Antofagasta, Centerra, Hochschild and Fortuna, among others.

Ravena financing

Concurrently with the reorganization, Ravena completed a non-brokered private placement of 4,962,815 common shares of Ravena at a price of 20 cents per share for aggregate gross proceeds of $992,563. The common shares were issued at fair value to a group of founders and arm's-length investors. Consistent with Riverside's spinout model, no securities were issued for nominal consideration. Ravena intends to use the net proceeds of the founder financing to advance Los Cuarentas project, including mapping, sampling and geophysical surveys, to update technical disclosure in support of the proposed listing, and for general and administrative expenses and working capital.

Ravena is not a reporting issuer in any jurisdiction. The common shares issued under the founder financing are subject to resale restrictions under applicable securities laws, including an indefinite hold period that will not begin to run until Ravena becomes a reporting issuer, and, on listing, to any hold periods or escrow that may be imposed by the exchange. No finders' fees were paid in connection with the founder financing. The founder financing consisted solely of common shares of Ravena, a subsidiary of Riverside, with no warrants or other rights attached.

The founder financing remains subject to the acceptance of the TSX Venture Exchange.

About Ravena Resources Corp.

Ravena is an advanced-stage mineral exploration company focused on high-grade gold-silver and copper-gold projects in Sonora, Mexico, a premier and established mining jurisdiction. Ravena's flagship asset is Los Cuarentas project, a past-producing, permitted and drill-ready low-sulphidation epithermal gold-silver system covering approximately 807 hectares, with four near-surface drill-ready targets and the potential for shallow underground mineralization as outlined by past drilling by Riverside. Los Cuarentas is located near a number of operating mines and developed deposits in the region, including Las Chispas, Santa Elena and Mercedes mines.

Ravena's broader portfolio includes the Cecilia (gold-silver), Ariel (copper-gold porphyry), El Valle (gold-silver) and Suaqui Grande (copper-molybdenum porphyry) projects. Ravena will have access to the Mexican database of information, operational infrastructure and technical services of Riverside, whose team has more than 30 years of experience operating in Mexico. Ravena is led by chief executive officer Michael Graham, an experienced public company executive with a mining capital market background, with Dr. Staude serving as non-executive chairman. Ravena is targeting a listing on the TSX Venture Exchange in the first half of 2027, subject to regulatory acceptance, completion of further financings and market conditions, and anticipates a tight, clean capital structure.
