Perfomance Highlights: (3Q17)

  • Quarterly gold production increased vs. 3Q16 as a result of the larger reduction in gold inventories at the leaching pads compared to the reduction in inventory level in 3Q16 and, to a lesser extent, increased volumes of ore processed. This was offset by the lower ore grade.
  • Year to date gold production decreased when compared to the same period of 2016 as a result of the lower ore grade at Herradura and the expected smaller decrease in gold inventories at the leaching pads compared to the larger reduction in inventory levels during 2016. However, these factors were partly mitigated by the higher volume of ore processed.
  • Quarterly gold production increased 13.3% vs. 2Q17 as higher ore grade from the Valles area was processed and to a lesser extent, higher volumes recovered due to increased irrigation of new mineral layers deposited on the leaching pads. These factors were partly offset by the lower volumes of ore processed.
  • Inventory levels are expected to continue decreasing at Herrradura in 4Q17, albeit at a lower pace.
