October 14, 2025 8:00 AM EDT | Source: Riverside Resources Inc. Vancouver, British Columbia--(Newsfile Corp. - October 14, 2025) - Riverside Resources Inc. (TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY0) ("Riverside" or the "Company") is pleased to announce the expansion of its rare earth elements program in British Columbia with work advancing at the Revel Project and additional target generation across Canada and Mexico. Riverside has identified an extensive carbonatite unit at the Revel Project and is prioritizing systematic work to refine exploration targets.

"Rare earth elements have been one of the focuses for Riverside and with the increasing global demand for critical minerals Riverside's generative approach is well suited in the hunt for these elements ("REE")," said John-Mark Staude, CEO of Riverside Resources. "For over 18 years we have executed a disciplined project generator model that turns geologic ideas into tangible assets for shareholders and Revel fits that playbook. We see a near to infrastructure-accessible carbonatite system with large (several kilometers) scale potential and are advancing this project with staged work programs that tighten the geology, de-risk access, and set up clear next stages of mineral exploration. In parallel we continue to build a pipeline of critical mineral assets that can be explored, partnered, optioned, or spun out, as we have done before with Capitan Silver and most recently with the Blue Jay Gold share distribution in May 2025. Our aim is simple. Make mineral discoveries and create value for stake holders. We develop optionality, limit dilution, and convert technical progress into transactions and retained royalties as we progress discovery and development including the focus on REE."

Program Highlights

Focus on Revel, a carbonatite-hosted REE target in southern British Columbia with access north of the Trans-Canada Highway.
Expansion of field work to include detailed mapping, spectral and geochemical sampling, and ground geophysics to vector toward high-grade REE zones.
Initiation of baseline and permit planning to enable first-pass drilling consistent with the exploration results.
Parallel generative work on additional REE opportunities in Canada and Mexico to seed future transactions.

Strategic Context and Riverside Business Model

Rare earth elements remain designated as critical minerals by the United States and Canada. Riverside efficiently operates a project generator model focused on discovery, partnerships, and selective spinouts. The company advances targets through early exploration to a decision point, then seeks partner funding, option agreements, or corporate transactions while retaining equity or royalty exposure. This approach has delivered value over 18 years through completed spinouts, partner-funded programs in Canada and Mexico, and the distribution of Blue Jay Gold shares to Riverside shareholders in 2025 at a five for one ratio. The REE program at Revel and the broader critical minerals pipeline are being advanced within this same framework to position assets for partnerships, drilling, or future spinouts.
