RYOOF) Secures Community Permission to Commence Site Activities at Maria Norte, Peru

Rio Silver Inc. (TSX-V: RYO | OTC: RYOOF) is
pleased to announce that it has received permission from the local
community to commence planned site activities at its Maria Norte
Project in Peru. The agreement allows the Company to begin
establishing the necessary infrastructure to efficiently start
exploration and development of the Maria Norte Property.

The agreement follows ongoing dialogue and participation from local
residents and community leadership. With this initial agreement, the
Company will continue to work with the local community and the
broader Huachocolpa community to enter into a formal definitive
agreement for the long-term use of the area for both exploration and
mining activities. Rio Silver may now proceed with planned access
preparation and related technical initiatives in alignment with the
community’s support.

Huachocolpa: A Community Built on Mining Heritage

The Huachocolpa District has long been recognized as a region rooted
in mineral development, with a proud legacy of resource extraction.
Compañia de Minas Buenaventura (“Buenaventura”),
Peru’s historic mining company, initially commenced operations
in this district in the 1950s. Buenaventura has, for decades in this
district, provided employment, technical training, and opportunity
for generations.

The district is home to a significant Canadian presence, including
neighboring operations led by Silver X Mining Corp. and Endeavour
Silver Corp., among others operating regionally. Canadian-led
companies in Peru have historically operated under rigorous
environmental, social, and governance standards, supported by strong
capital markets and disciplined regulatory frameworks. Rio Silver is
committed to upholding those same principles of transparency,
accountability, and long-term partnership.

Management Commentary

“We are extremely grateful for the active and thoughtful
participation demonstrated by the surrounding community,”
said Chris Verrico, President and Chief Executive Officer of Rio
Silver. “The response from our host neighbors reflects
strong leadership, solid intentions, and a shared commitment to
ensuring development proceeds in a manner that benefits all
stakeholders.”

“Huachocolpa is a community shaped by mining expertise and
integrity. We recognize that the opportunity to advance Maria
Norte comes with responsibility. We are honored to build upon the
legacy established by those who developed this region before us,
and we are committed to maintaining open dialogue, respecting
local values, and working collaboratively as we move forward. With
this initial step achieved, we are excited to continue working
with all stakeholders to enter into a definitive agreement in
2026. The future for the project and for our partnership with the
community is truly exciting.”

Immediate Next Steps

With formal authorization confirmed, the Company intends
to:

• Mobilize personnel to initiate planned site activities
• 
  Advance access and portal preparation work, including camp
  construction
• 
  Advance mineral process optimization (metallurgical) programs
• 
  Conduct systematic surface mapping and technical field programs

These activities are structured to ensure steady advancement while
maintaining continued engagement and cooperation with local
stakeholders.

Metallurgical Program Advancing to Support Silver Recovery
Optimization

The Company also confirms that its previously announced
metallurgical program to de-risk processing and optimize silver
recoveries at Maria Norte remains actively underway. This technical
work is focused on validating processing assumptions, refining the
proposed flow sheet design, and supporting the Company’s
staged development strategy. Upon receipt and review of the
metallurgical results, Rio Silver intends to provide a comprehensive
update to the market.
