Location

Segovia Mining District, Colombia

  • The Guia Antigua Project is a mining license agreement for the exploration development and mining in a 386 hectare area within the eastern part of GCM’s mining title RPP-140 in the Segovia Mining District
  • GCM Mining Corp. carries out mining, processing and production of gold from their flagship Segovia operations El Silencio, Providencia and Sandra K mines on the adjacent, western part of the mining title RPP-140
  • These high-grade mines have been in continuous operation for over 150 years and over that time have produced roughly 6 million ounces of gold

Geology

Vein System Potential

  • 2018 drill program identified 3 new veins and excellent grades including a high mineralized intercept of 3,268 g/t Ag, 8.57 g/t Au across a 1.2m drill length
  • The Guia Antigua vein is the current focus of the Guia Antigua Project which is similar in geology, structure, vein style and mineralogy to the veins of the High Grade Segovia Operations
  • Early exploration indicates very strong potential for further discoveries in the area
  • Completing ongoing soil survey, infill soil sampling and ground magnetics. Conducting exploration diamond drilling campaign of the Guia Antigua Vein and other veins by 15 holes of 200m length each for a total of 3,000m
