Rio Silver talks up Maria Norte project

Executive Summary

• Rio Silver Inc. provides geological and operational context for its Maria Norte project in Peru, highlighting its location within a proven silver-gold mineralized corridor adjacent to Silver X Mining Corp.'s Tangana mining unit.
• The company outlines its exploration strategy, noting that the property has been held for 18 years with limited modern exploration, and plans to advance systematic surface mapping and sampling during the third quarter of 2026.
• Management emphasizes the potential for high-impact development targets due to underexplored ground and historical mineralization that was previously considered uneconomic, with near-term focus on securing access, permits, and initiating adit development.

Key Details

• Project Location & Context: Maria Norte is located within the same regional mineralized corridor as Silver X Mining Corp.'s Tangana mining unit, separated by a regional fault.
• Vein Systems: The project hosts multiple mapped mineralized structures, including the Castor, Maria, Pamela, and Jess veins, and approximately 500 metres of the Las Animas vein set.
• Historical Production Context: The adjacent Tangana area operated as a lead-zinc mining camp between 1960 and 1975, extracting approximately 234,098 tonnes from four principal vein sets across a 2.5 km horizontal extent and 960 m vertical range.
• Sample Data: A single independent reference sample from a reclaimed waste dump (associated with a rumored 400m historic tunnel) returned 12.7 oz/t silver and 2.194 g/t gold. The company notes this material was historically discarded and the sample is not representative of overall mineralization.
• Exploration History: Limited to surface mapping and selective sampling over the last 18 years; several exposed veins remain undocumented by modern methods.
• Upcoming Exploration: Plans to advance systematic surface mapping and sampling during the third quarter of 2026 dry season, subject to access and permitting.
• Technical Studies: Rio Silver has not completed a preliminary economic assessment (PEA) on the Tangana West vein system portion of the project. Silver X has completed a NI 43-101 compliant PEA for its Tangana unit, used here solely for district context.
• Near-Term Focus Areas:
  • Finalizing community access agreements.
  • Completing access and portal preparation.
  • Securing necessary permits for development and mining.
  • Initiating adit development and driving a drift along the Maria vein.
  • Advancing metallurgical, processing design, and technical studies.
• Qualified Person: Jeffrey Reeder, PGeo, reviewed and approved the technical information.

Notable Quotes

• "Maria Norte sits within a proven silver district, and the structural setting gives us a compelling geological framework to work from," said Chris Verrico, chief executive officer of Rio Silver.
• "What excites us is not only the extent of underexplored ground relative to nearby operations, but the fact that much of this mineralization was historically overlooked when silver and gold prices were a fraction of where they are today."
