Riverside Resources completes first financing for Ravena Resources ahead of TSX Venture spinout

Riverside Resources Completes First Financing for Ravena Resources Corp. in Advance of Proposed TSX Venture Spinout

VANCOUVER, British Columbia, July 13, 2026 (GLOBE NEWSWIRE) -- Riverside Resources Inc. (“Riverside” or the “Company”) (TSX-V: RRI) (OTCQB: RVSDF) (FSE: 5YY0) is pleased to announce that it has completed an internal reorganization (the “Reorganization”) of its subsidiary, formerly named RRI Holdings Limited and now renamed Ravena Resources Corp. (“Ravena”), and that Ravena has completed an initial founders’ financing (the “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 (the “Exchange” or “TSX-V”), a process that could occur following additional financing and shareholder approval, consistent with Riverside's approach with Capitan Silver (CAPT.V) and Blue Jay Gold (JAY.V) over the past several years.

“The creation of Ravena follows the same disciplined spin-out 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 John-Mark Staude, President and CEO 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 an 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, S.A.P.I. de C.V. (“SAPI”), a portfolio of five exploration projects located in Sonora, Mexico: Los Cuarentas (flagship), Cecilia, Ariel, El Valle and Suaqui Grande (collectively, the “Mexican Projects”). Maps and descriptions of these properties are available on Riverside's website. Over the past decade, the properties have received exploration funding 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 C$0.20 per share for aggregate gross proceeds of C$992,563. The common shares were issued at fair value to a group of founders and arm’s length investors. Consistent with Riverside’s spin-out model, no securities were issued for nominal consideration. Ravena intends to use the net proceeds of the Founder Financing to advance the 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 finder’s 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-V.
