Rio Silver Highlights Underexplored Silver-Gold Potential at Maria Norte Within a Proven Peruvian Mining District
VANCOUVER, British Columbia, Feb. 05, 2026 – Rio Silver Inc. (TSX-V: RYO | OTC: RYOOF) has provided detailed geological and operational context for its Maria Norte Project, emphasizing its location within a proven mineralized corridor in Peru. The company's analysis focuses on the project's proximity to the adjacent Tangana Mining Unit operated by Silver X Mining Corp., based on publicly available technical disclosures.
District Context and Structural Setting
The Maria Norte Project hosts multiple mapped mineralized structures, including the Castor, Maria, Pamela, and Jess Veins, along with approximately 500 metres of the Las Animas vein set. These vein systems occur along the same regional structural corridor and lie approximately 600 metres from vein extensions currently comprising SilverX's Tangana Mining Unit, separated by a regional fault.
Rio Silver emphasizes that this geological context illustrates the proven endowment of the district while noting that mineralization on adjacent properties is not necessarily indicative of mineralization on the company's property.
Mineralization Characteristics and Historical Context
Mineralized exposures traced at Maria Norte to date extend up to approximately 1,000 metres and show elevated silver and gold values with lesser lead and zinc, consistent with a silver-dominant vein system. In comparison, the Tangana area historically operated as a lead-zinc mining camp between 1960 and 1975, during which approximately 234,098 tonnes were extracted from four principal vein sets across a combined horizontal extent of approximately 2.5 kilometres and a vertical range of approximately 960 metres.
At Maria Norte, evidence of a rumoured historic tunnel or adit of approximately 400 metres is supported by the presence of a reclaimed waste dump. A single independent reference sample collected from this dump returned 12.7 ounces per tonne silver and 2.194 g/t gold. This material was historically discarded as uneconomic under previous operating conditions. Rio Silver clarifies that this sample is not representative of mineralization at Maria Norte and should not be relied upon for assessment purposes.
Project Status and Adjacent Property Disclosure
Rio Silver controls a portion of the Tangana West vein system within the Maria Norte Project area, however the company has not completed any economic study, including a Preliminary Economic Assessment, on this portion of the project. Silver X Mining Corp., which operates adjacent mining units within the same regional mineralized corridor, has completed a NI 43-101–compliant Preliminary Economic Assessment covering its Tangana Mining Unit.
Rio Silver references this study solely to provide geological and operational context within the district, emphasizing that information derived from Silver X's technical report is not indicative of mineralization, mineral resources, mineral reserves, or economic outcomes on Rio Silver's property and should not be relied upon for investment decisions.
The company's disclosure highlights the underexplored potential of the Maria Norte Project while maintaining appropriate caution regarding extrapolations from adjacent operations, providing investors with contextual information about the project's setting within a historically productive Peruvian mining district.
