  • Age of host rock: Eocene.
  • Alteration: argillic, silicification, propylitic, iron oxide, alunite, jarosite.

Reserve Amount

Copper: The proven reserve mentioned in discovery certificate for copper is 100,000 tonnes with average grade of 0.7%. It should be noted that further deep drilling is needed to fully explore this reserve, and the reserve may increase several times after completion of exploration.

Iron: According to the exploitation license, proven reserve of iron with average grade of 31% of the hematite is estimated 65,000 tons.

Facilities

close to asphalted  road, the presence of dirt road to mineralization areas and the presence of water, electricity and gas near the area.
