Highlights 

  • High-grade gold intercepts reported from Pepas infill and metallurgical drilling campaign 
  • Soil survey at El Cedro confirms extensive gold-bearing porphyry system with strong expansion potential 
  • Drilling to commence shortly at El Pantano Project, Argentina 

Orosur Mining Inc. (TSXV:OMI) has provided an update on exploration activities at its Anzá Project in Colombia and El Pantano Project in Argentina. 

The Anzá Project, covering approximately 330 km² within Colombia’s Mid-Cauca gold belt, is now wholly owned by Orosur following the 2024 acquisition of Minera Monte Aguila S.A.S. from Newmont Mining and Agnico Eagle Mines. Current work is concentrated across three key prospects — Pepas, APTA, and El Cedro. 

High-Grade Gold Results at Pepas 

Orosur reported assay results from three drill holes at the Pepas prospect, part of its infill and metallurgical program designed to support a NI 43-101 compliant Mineral Resource Estimate expected by year-end. 

Significant intercepts include: 

  • PEP065: 33.3m @ 2.84g/t Au 
  • PEP065B: 33.8m @ 2.79g/t Au 
  • PEP066 (metallurgical): 112m @ 5.25g/t Au from surface 

Hole PEP066, drilled with a larger PQ core for metallurgical testing, intersected with multiple zones of high-grade mineralization. 

El Cedro Survey Confirms Large Gold Porphyry System 

At El Cedro, located 4 km south of APTA, Orosur completed an extensive soil geochemical survey revealing anomalous gold concentrations exceeding 1 g/t Au in several samples. 

Geological evaluation suggests El Cedro hosts multiple porphyry intrusions, including a newly identified system to the south.  

Drilling Set to Begin at El Pantano, Argentina 

The El Pantano Project in Santa Cruz Province, Argentina, spans approximately 550 km² and is managed under a joint venture with Deseado Dorado S.A.S. Orosur holds a 51% interest, with the right to earn full ownership through an additional investment of USD 2 million by February 2027. 

A 3,000m diamond drilling program will commence shortly — the first-ever drilling campaign on this property — to test multiple geophysical and geochemical anomalies along a 25 km-long epithermal trend. 

CEO Commentary 

Brad George, CEO of Orosur Mining, stated: 
“Following our recent capital raise, we are fully funded to accelerate exploration. Our focus on strong geological fundamentals, 100% ownership, and near-term production opportunities continues to deliver results, positioning Orosur favorably in this strong gold market.”
