Newmont Achieves Commercial Production at Twin Creeks Underground Expansion Gold Project

Newmont Mining Corporation has achieved commercial production at its Twin Creeks Underground expansion project, adding higher-grade, lower-cost gold production at its Twin Creeks operation in Nevada. The project was completed on schedule for $42 million, slightly below guidance of between $45 and $55 million.

The Twin Creeks Underground mine will add between 30,000 and 40,000 ounces of gold production per year at all-in sustaining costs of between $650 and $750 per ounce for its first five years of production. This new ore will also allow Newmont to process stockpiled ore that had previously been classified as waste, and extend processing life to 2030.

"The expansion extends profitable production and improves recoveries at Twin Creeks, and serves as a platform to further explore the deposit, which remains open along strike and at depth," said Gary Goldberg, President and Chief Executive Officer. "This project marks the sixth that Newmont has completed on or ahead of schedule and at or below budget over the last five years, and generates an internal rate of return of about 20 percent."

The Twin Underground mine is mechanized, featuring remotely-operated loaders to improve safety and efficiency. Twin Underground ore will also be blended with ore from Turquoise Ridge. In early 2018, Newmont and Barrick Gold Corporation approved the Turquoise Ridge Mine Optimization project, which involves sinking a production shaft to access the richest part of the deposit. The new shaft is expected to increase ventilation capacity and lower unit costs by more than 20 percent, while increasing ore production rates to at least 1.1 million tons per annum when it comes on line in 2022.

Over the last five years, Newmont has built six new mines and expansions on four continents, including Akyem and the Phoenix Copper Leach in 2013, Merian and Long Canyon in 2016, and Tanami in 2017. The Company also completed a value-accretive acquisition of Cripple Creek and Victor in 2015 and delivered a profitable expansion at the mine in 2016.
