Centauro Deep

Ownership: Minera Penmont (100% Fresnillo plc)
Location: Sonora, below Centauro main pit at Herradura

Key Exploration:

  • Drilling 9,000m, extensive re-logging of core samples and mapping of workings in the Centauro and Valles areas carried out to better define the resource model and identify new veins below the pits
  • Bulk sampling carried out to determine the grade in areas with coarse gold, and an updated estimate made of the resources
  • Further geological modelling carried out and works on a pilot stope continued in order to further refine the model and more accurately determine the ore bodies to define the optimal mining method: a bulk mining method with lower grades or a more selective mining method extracting only the higher gold grade material
  • Expected to commence production in 2020, and produce an annual average of 65 thousand ounces of gold, if the selective mining method is ultimately chosen
  • Channel sampling and revision of the resource models were conducted at the Centauro gold deposits, preliminary economic studies will be advanced in 2017
