Elements Program Including at Revel Project,

British Columbia

Company looks to acquire additional REE projects in Canada

and Mexico

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.
