Perfomance Highlights:
- Full year gold production increased as a result of the reduction of inventories to 72 koz at Herradura. This reduction was possible by the commissioning of the second Merrill Crowe Plant in the DLP (Dynamic Leaching Plant) in 4Q15, which enabled the elimination of the bottleneck in processing volumes of rich solution coming from the leaching pads and the DLP
- Quarterly gold production increased vs. both 4Q15 and 3Q16 mainly due to the reduction of inventories and, to a lesser extent, a higher overall average speed of recovery resulting from the increase in the use of lime that improved the leaching reaction and more than compensated for the lower ore grade
Objectives: 2017
- Advance construction of the 2nd line of the DLP
- Increase exploration at Centauro
