High-Grade Silver Confirmed by Verification Sampling

As part of the independent National Instrument 43-101 review, verification sampling was conducted by James A. McCrea, P.Geo., the independent author of the NI 43-101 Technical Report, during a site visit to the Maria Norte Project in June 2025. Sampling targeted surface vein exposures and historic waste material and returned high-grade silver values, including:

• 869 g/t silver, with associated lead and zinc, from a 5-metre surface vein channel sample
• 991 g/t silver from a 7-metre surface vein channel sample
• 396 g/t silver from a historic waste dump grab sample

Table 1: Maria Norte Verification Sampling Results (NI 43-101)*

*Verification sampling returned silver values ranging from 396 g/t Ag to 991 g/t Ag, with associated lead, zinc, and localized gold values. These results confirm the presence of high-grade silver mineralization at surface, consistent with historical sampling by previous operators and characteristic of low-sulphidation epithermal vein systems common to the Huachocolpa District.

A total of four (4) verification samples were collected, consisting of three (3) chip samples from surface vein outcrops and one (1) grab sample from a historic waste dump, with chip sample widths ranging from approximately 0.4 metres to 0.7 metres. All samples were bagged, labelled, and sealed in the field using single-use security ties, transported by the author to Lima, Peru, and analyzed by Certamin S.A., an ISO 9001–certified laboratory located in the Santiago de Surco municipality of Lima.

No additional quality control samples (blanks, standards, or duplicates) were inserted due to the limited number of samples collected, which the author considered appropriate for the exploration stage of the project. James A. McCrea, P.Geo. concluded that the sampling methods, sample handling, preparation, and analytical procedures are adequate for data verification purposes, and that the results are representative of the surface mineralization observed at Maria Norte.

CEO Comment

“The confirmation of high-grade silver at Maria Norte reinforces what initially attracted us to this project,” said Chris Verrico, President and Chief Executive Officer of Rio Silver. “These are good grades in a district known for long-life silver production, and as our team continues work on the ground, we are seeing encouraging geological indications that suggest the system may extend beyond what is currently exposed. Combined with existing infrastructure, favorable metallurgy, and strong community engagement, we believe Maria Norte offers a compelling opportunity to advance toward development while continuing to unlock further upside.”

 

Proven Geological Setting in a Renowned Silver District

Maria Norte is situated within the Miocene polymetallic belt of central Peru, a region that has supported decades of silver production from structurally controlled epithermal vein systems. Mineralization at Maria Norte occurs within quartz-sulphide veins and breccias, hosting silver-dominant mineralization with associated lead, zinc, and local gold values.

Mapping and structural interpretation indicate that mineralization is controlled by a well-defined vein corridor with favorable geometry for continuity along strike and at depth. This geological setting mirrors other productive operations in the district and supports the Company’s development-focused exploration strategy.

Infrastructure, Metallurgy, and Development Readiness

Historic metallurgical test work reviewed by the Company indicates that mineralization at Maria Norte responds to conventional flotation methods. Combined with the project’s location within a well-established mining district, this supports a development approach that emphasizes efficiency and capital discipline.

Key advantages at Maria Norte include:

• Favorable Metallurgy: Historic test work indicates amenability to conventional flotation processes.
• Established Infrastructure: Road access and operating processing facilities are located approximately 11 kilometers from the project.
• Reduced Capital Intensity: Proximity to existing mills has the potential to lower upfront capital requirements, shorten development timelines and reduce exposure to environmental costs related to mill operation.
• Experienced Mining District: Maria Norte is located within one of Peru’s longest-producing silver regions, which has a well-established, supportive mining culture, and experienced local workforce.

Following the recent approval of the Maria Norte acquisition, Rio Silver has advanced boots-on-the-ground activities, including site access planning, infrastructure assessments, and early permitting preparations. In parallel, the Company continues constructive engagement with local community leaders, building on a foundation of cooperation in one of Peru’s most established and supportive mining regions.

Positioned for Near-Term Development

Rio Silver’s strategy at Maria Norte is focused on advancing accessible, high-grade mineralization through staged development while continuing exploration to expand the known system. Under Peru’s established exploration and exploitation framework, development activities can progress alongside exploration, allowing the Company to advance the project efficiently and responsibly.

Management believes that the combination of verified high-grade silver, nearby processing capacity, and an experienced in-country team places near-term development firmly within the Company’s strategic horizon, subject to continued technical success and permitting.

Next Steps

• Advance Development Planning at Maria Norte: Continue site preparation activities, infrastructure assessments, and permitting work in support of staged underground access targeting accessible high-grade silver mineralization.
• Expand Geological Understanding of the System: Complete detailed mapping, channel sampling, and geophysical surveys to refine priority targets and assess continuity along strike and at depth within the known vein corridor.
• Progress Community and Stakeholder Engagement: Maintain active dialogue with local communities and stakeholders to finalize access agreements and support responsible development as work programs advance.
• Parallel Metallurgical Work at Santa Rita: Advance ongoing metallurgical test work to better understand mineral processing characteristics while technical evaluations and project integration continue.

Why This Matters to Investors

As global silver markets continue to experience structural supply deficits, projects capable of advancing high-grade silver toward development are scarce. Maria Norte stands out due to its verified grades, district-scale setting, proximity to operating mills, and disciplined development strategy. With key technical milestones achieved and field activities advancing, Rio Silver believes it is well positioned to deliver continued progress and value creation for all stakeholders as the silver cycle unfolds.

Rio Silver Issues Year-End Shareholder Letter as Silver Hits Record Highs and Company Advances a Clear Path Toward Production

Highlights Near-Term Development at Maria Norte, District-Scale Exploration Upside in Peru, and Strategic Optionality from Canada’s Ring of Fire Critical Minerals Asset

Vancouver, British Columbia – Dec. 24, 2025 – Rio Silver Inc. (“Rio Silver” or the “Company”) provides the following year-end update and shareholder letter from President and Chief Executive Officer Chris Verrico, outlining the Company’s strategic positioning amid record silver prices, its clear development pathway at the Maria Norte Project in Peru, and the exploration and long-term growth opportunities across its broader portfolio.

Dear fellow shareholders,

As we approach the end of the year, I want to take a moment to speak directly to our shareholders and reflect on where we are, the environment we are operating in, and where Rio Silver is headed next.

It has been an extraordinary year for silver. Prices have reached all-time highs, driven not by speculation, but by fundamentals that continue to strengthen. According to industry data and independent analysis, the silver market has now entered its fifth consecutive year of structural deficit, with industrial demand accelerating faster than supply can respond. Silver is being consumed at record levels by solar energy, electrification, data infrastructure, and advanced manufacturing, while at the same time continuing to serve its historical role as a monetary asset during periods of economic uncertainty. Simply put, silver is being pulled from both sides of the equation, and supply has struggled to keep pace.

This backdrop is exactly why we have been so focused on building Rio Silver into a pure-play, high-grade silver company with a realistic and disciplined path to development.

This year culminated in an important milestone with the official approval of the Maria Norte acquisition, which we believe marks a turning point for the Company. Maria Norte is not a conceptual exploration project. It is a high-grade silver asset located in one of the world’s most prolific silver districts, with a skilled local workforce, and operating processing facilities just 11 kilometres away. With exchange approval now secured, our team is already advancing next steps, including social licience, site preparation, infrastructure planning, permitting activities, and underground access sequencing. Our objective is clear: move Maria Norte along a practical path toward production while advancing exploration in parallel under Peru’s established exploration and exploitation framework.

Looking ahead to 2026, shareholders can expect a steady cadence of updates as we progress through development milestones, engineering work, and exploration initiatives. Our focus remains on executing efficiently, prioritizing accessible high-grade mineralization first, and positioning the Company for near-term cash flow potential while preserving long-term upside.

Beyond Maria Norte, we are excited about the exploration potential at Santa Rita. While still early, Santa Rita is situated within a highly prospective geological setting known for hosting large-scale polymetallic systems. Historical work has outlined multiple styles of mineralization and a broad surface footprint that we believe warrants systematic follow-up. As we advance Maria Norte, Santa Rita represents an important component of our longer-term growth strategy and district-scale potential.

We also continue to recognize the significant opportunity represented by our Ring of Fire critical metals project in Northern Ontario. This asset is supported by encouraging historical work and is located in a region that has increasingly become a strategic priority at both the provincial and federal levels. We have been encouraged by ongoing dialogue with local First Nations communities and by recent policy developments aimed at responsibly advancing Canada’s critical minerals sector. This project provides meaningful optionality and long-term value, and we look forward to sharing key developments as we advance the Ring of Fire project in the near future.

In addition to advancing our core development assets, we enter 2026 with the benefit of several retained royalty interests and an equity position in Magma Silver Corp., which provide added flexibility and optionality as we move forward. These interests give us exposure to external project progress without requiring additional capital, helping support our balance sheet while allowing us to remain focused on advancing high-grade silver development in Peru. We believe this complementary exposure strengthens our overall position as we continue to execute on Maria Norte and build long-term value through the next phase of the silver cycle.

As we look forward, I am confident that 2026 will be a defining year for Rio Silver. With silver prices at record levels, a clear development path at Maria Norte, meaningful exploration upside across our portfolio, and a strong team on the ground, we believe we are well positioned to create value for our shareholders, partners, and stakeholders.

On behalf of the entire Rio Silver team, I would like to sincerely thank you for your continued support and belief in our vision. I wish you and your families a Merry Christmas and Happy Holidays, and I look forward to what I believe will be an exceptional year ahead as we work toward delivering our strongest year yet for all stakeholders.

Sincerely,

Chris Verrico

Rio Silver Acquires Second High-Potential Silver-Lead-Zinc Project in Central Peru

Santa Rita acquisition expands Rio Silver’s district-scale presence with high-grade CRD mineralization, complementary geology to Maria Norte, and the infrastructure advantages needed to advance a near-term, pure-play silver development strategy in Peru

Vancouver, British Columbia – December 2, 2025 – Rio Silver Inc. (TSX-V: RYO | OTC: RYOOF) (“Rio Silver” or the “Company”) is pleased to announce that its Peruvian subsidiary, Rio Plata S.A.C., has acquired the Santa Rita Pb-Zn-Ag Property, a highly prospective exploration target with extensive historical workings and strong silver-lead-zinc showings in Central Peru.

A representative sample has been submitted for metallurgical testing, which is now underway. Historical work completed by previous operators has guided Rio Silver’s internal evaluation, and the Company will provide further disclosure as the metallurgical review advances toward completion.

Santa Rita was secured through a closed-bid auction for USD $130,000.00, a process that grants the winner a clear and unencumbered title. Rio Plata was the successful bidder and is now proceeding through Peru’s standard title confirmation process, expected to take approximately two to three months. The property comprises 570 hectares and lies within one of Peru’s richest mineral belts.

Strategic Location in a Premier Silver Belt

Santa Rita is situated approximately 200 km ESE of Lima, with road access from two directions and in close proximity to significant regional silver-lead-zinc operations. The project is located:

• 55 km northwest of Rio Silver’s flagship Maria Norte Au-Ag-Pb-Zn Project, and
• 14 km southwest of Kuya Silver’s producing Bethania Mine (TSX-V: KUYA).

This corridor hosts a concentration of long-life underground operations, carbonate-replacement deposits (“CRDs”), and active processing capabilities, making it one of the most productive polymetallic regions in Peru.

Geology and Historical Work

Extensive exploration was conducted at Santa Rita by Inca Minerals between 2016 and 2020 under an option agreement that was subsequently relinquished due to rising underlying payments—not geological limitations. Following non-payment of annual taxes, the area reverted to the state in 2024 and became available for new application in mid-2025, at which point Rio Plata secured it.

Historical work identified Santa Rita as a Carbonate Replacement Deposit (CRD) system characterized by:

• 20+ steeply dipping east-west veins,
• Intersecting shallow-dipping mantos

Two priority zones were highlighted—Humaspunco East and Humaspunco South—with mineralization hosted within carbonate sequences.

A Strengthened District-Scale Vision

“Santa Rita sits in the same mineralized corridor as our principal Maria Norte Project, and its acquisition meaningfully expands our footprint within what we see as an emerging silver district in Central Peru,” said Chris Verrico, President and CEO of Rio Silver. “Securing this project through a clean, closed-bid process gives us 100% ownership with no underlying royalties or option obligations, which aligns perfectly with the disciplined approach we are taking across our portfolio. The reported high-grade CRD veins currently being confirmed by our field team reinforce the near-term development potential we are targeting, and Santa Rita adds another important building block as we advance our strategy to establish Rio Silver as a pure-play silver developer in one of the world’s most prolific jurisdictions.”

Next Steps for Rio Silver

• Pending Approval of Maria Norte Acquisition: The Company looks forward to announcing the formal closing of the Maria Norte transaction upon TSX Venture Exchange approval, which will enable immediate commencement of planned fieldwork and early development activities.
• Metallurgical Testing Underway: A representative sample from the Santa Rita Project is currently undergoing metallurgical evaluation, and the Company anticipates providing an update as the review advances toward completion.
• Near Term Development Pathway: Preparations are underway for initial onsite work programs including camp installation, portal access upgrades, and explosives permitting. These steps support Peru’s established exploration and exploitation model and allow development to advance alongside exploration and resource definition.
• Infrastructure and Cost Advantages: Both Maria Norte and Santa Rita benefit from proximity to multiple regional processing facilities within trucking distance, providing an opportunity to advance high grade silver assets quickly and at comparatively lower capital intensity.
• Strong Exploration and Market Tailwinds: With high grade CRD and vein systems identified across both projects and further target refinement underway, the Company is positioned to advance exploration in a period of record high silver prices and tightening global supply, creating meaningful upside exploration potential as work progresses expediently.

Why This Matters to Investors

The addition of Santa Rita further positions Rio Silver at the center of one of Peru’s most prospective silver-lead-zinc regions. The project offers:

• High-grade CRD mineralization with strong Ag-Pb-Zn values,
• Low-entry cost and 100% ownership with no royalties,
• Road access and proximity to producing mines and processing centers,
• Geological continuity with the mineralized belt hosting Maria Norte,
• A scalable platform for district-wide growth with synergies between projects.

Together with Maria Norte, the addition of Santa Rita accelerates Rio Silver’s evolution into a pure play, district focused silver developer in one of the world’s premier silver jurisdictions. These assets establish a foundation with meaningful exploration upside and clear pathways for near term advancement.

Rio Silver Provides Corporate Update as the Company Advances Toward High-Grade Silver Development in Peru

Strategic groundwork underway at Maria Norte as Rio Silver positions itself to become a next-generation silver developer in one of the world’s most prolific mineral belts

Vancouver, British Columbia – Nov. 25, 2025 – Rio Silver Inc. (TSX-V: RYO | OTC: RYOOF) (“Rio Silver” or the “Company”) is pleased to provide a corporate update outlining ongoing operational preparations and strategic initiatives as the Company advances toward becoming a high-grade silver producer in Peru, the world’s second-largest silver-producing nation.

Over recent weeks, Company President Chris Verrico, in-country Peruvian Project Manager and Geologist Miller Fernandez, Logistics Manager José Peña and Principal Geological Consultant Edgar Leon, completed a detailed site visit to the Maria Norte Au-Ag-Pb-Zn Project. The team confirmed the scope, sequencing, and logistical requirements to fast-track development work immediately upon regulatory approval of the pending acquisition.

Operational Highlights

• Development Program Ready to Launch: Field team completed a full development review at Maria Norte, confirming immediate sequencing and readiness to begin work upon Exchange approval of the acquisition.
• Infrastructure and Portal Access Advancing: Preparations underway for high-altitude camp construction, laydown areas, portal-access upgrades, and drift/tunnel advancement along known mineralized structures.
• Permitting and Community Agreements Progressing: Explosives permitting and final stakeholder access agreements are advancing positively within one of Peru’s most established silver-producing regions.
• Leveraging Peru’s Proven Development Model: The Company is adopting Peru’s exploration/exploitation framework, enabling mineral generation while concurrently establishing underground drill platforms for resource definition.
• Strengthened Treasury and Strategic Alignment: Rio Silver remains well funded by a diversified, supportive investor base, and Maria Norte lies on-strike with nearby mine developments supported by a positive PEA. 
• Evaluating Additional District-Scale Opportunities: Management has identified several silver-dominant targets within trucking distance that may offer accretive district-scale growth potential.

 

“Rio Silver is laying the foundation for what we believe can become one of Peru’s next high-grade silver operations,” said Chris Verrico, President and CEO. “Our recent technical review confirmed the strength of the mineralized structures at Maria Norte and validated our plan to advance a rapid, efficient development model. With strong local support, a skilled in-country team, and a well-funded treasury, we are moving with purpose toward unlocking the full potential of this emerging silver district. We see a tremendous opportunity ahead—not only at Maria Norte, but across the broader belt where we continue to evaluate additional high-grade prospects.”

Royalties and Additional Strategic Interests

Rio Silver also benefits from a suite of long-term royalty and equity interests that strengthen the Company’s financial position and provide meaningful, non-dilutive value as it advances its core Peruvian portfolio.

The Company currently receives approximately US$150,000 per year in advanced royalty payments, forming a stable baseline of recurring revenue. In addition, the sale of the Niñobamba project to Magma Silver Corp. provides Rio Silver with milestone payments exceeding US$2 million, along with 2,500,000 common shares of Magma Silver and a further 2,500,000 shares on the first anniversary of approval (see news release here). Magma Silver Corp. last traded at $0.20 per share as of market close on November 24, 2025, underscoring the tangible value of this equity exposure. Rio Silver also retains a 2% NSR royalty on Niñobamba, complementing the 3% capped NSR royalty held from the Company’s former Palta Dorada interests.

Beyond its Peruvian assets, Rio Silver maintains ownership of a highly prospective critical-metals project in Ontario’s Ring of Fire, one of Canada’s most important emerging mineral districts. A 2012 airborne EM survey conducted by Fugro identified one of the strongest electromagnetic anomalies ever recorded by the firm—an indicator of significant subsurface potential. Historical drilling by INCO in the 1970s intersected encouraging geology but was never advanced due to non-technical circumstances of the era. Today, Rio Silver continues to engage positively with local First Nations communities as it evaluates the long-term potential of this strategically located asset.

Why This Matters to Investors

Peru remains one of the world’s most important silver jurisdictions, hosting multiple long-life underground mines and well-established infrastructure. Rio Silver is advancing a strategy centered on:

• High-grade, high-margin silver mineralization in a district with proven production potential.
• A rapid development model that allows for resource delineation and mineral generation concurrently—an approach widely used in Peru.
• Proximity to established processing facilities, reducing potential future capital requirements.
• A district-scale vision, with additional prospective acquisitions under evaluation.
• A tight, aligned shareholder base and a strengthened treasury to support near-term catalysts.

As global silver demand accelerates—driven by industrial electrification, AI-related infrastructure, renewable energy, and precious-metal investment—Rio Silver is positioning itself as a pure-play developer with meaningful leverage to rising silver markets.

Engagement With Leading Communications Firm Caram Media
Partnering with Caram Media strengthens Rio Silver’s commitment to disciplined growth, clear market communication, and strong alignment with shareholders as the Company advances its near-term development strategy in one of the world’s most historically productive silver belts.

Galen Carson, President of Caram Media, commented: “We’re excited to partner with Rio Silver as they advance one of the most compelling emerging silver stories in Peru. Our team looks forward to helping bring this remarkable opportunity to the broader market with clarity, precision, and the strategic focus it deserves. It’s an inspiring project with tremendous energy behind it, and we’re thrilled to support the next phase of Rio Silver’s journey.”
