Orosur Mining Inc Announces New Mineralised Zones Discovered at APTA

Orosur identified new mineralised zones at Apta containing 1.0 g/t gold over 2.0 metres, adding to the project’s resource potential.

By The Northwire Desk — AI Analysis Jun 09, 2026 · 02:00 OMI · 0.37 Orosur Mining Inc.
Executive Summary
  • Orosur Mining Inc. announced the first drill result (MAP-106A) from its APTA prospect at the 100%-owned Anza Project in Colombia.
  • The hole returned a composite intersection of 229.7m @ 0.88g/t Au, including multiple higher-grade intervals up to 7.65m @ 7.07g/t Au.
  • Results validate a new geological model where mineralization is structurally controlled by the Aragon fault zone, hosted within silicified sediments and volcaniclastics.
  • Management identified three priority exploration areas: expanding deeper/high-grade zones, testing shallow bulk tonnage potential, and delineating a narrow hanging-wall vein system.
  • The announcement follows historical drilling of ~39,000m at APTA that previously lacked a coherent resource model due to geological debates.
Material Impact
  • The update is a direct follow-up to the April and May 2026 announcements regarding APTA drilling commencement and initial progress.
  • It materially advances the exploration thesis by confirming the new fault-controlled geological model, which significantly enhances the prospectivity of the broader Anza project beyond the already-defined Pepas resource.
  • The results are in line with management's stated expectations for the APTA target. While the average grade is modest, the thickness and structural continuity provide a solid foundation for future resource definition.
  • No immediate change to the near-term production timeline or financial outlook is triggered, as APTA remains in the exploration phase.

Company Overview
  • Orosur Mining Inc. is a junior exploration and development company focused on the 330km² Anza Project in the Mid-Cauca gold belt of Colombia.
  • The company holds 100% ownership via subsidiaries Minera Anzá and Minera Monte Aguila, acquired in November 2024 from Newmont Mining and Agnico Eagle Mines.
  • Pepas: The flagship deposit recently declared a maiden NI 43-101 resource of 219,000 oz Au (Indicated and Inferred). It is now advancing into economic studies and permitting.
  • APTA: A high-potential prospect where new drilling has validated a fault-controlled gold system, opening up significant exploration upside.
  • El Cedro: A porphyry-style system showing widespread high-grade soil geochemistry, with drilling planned for 2026.
  • El Pantano: A 51%-owned JV in Argentina targeting low-sulphidation epithermal gold-silver mineralization.
