Pretium Progressing On Mill Upgrades At Brucejack Mine
(Kitco News) - Mill modifications and upgrades required to sustain processing at the increased production rate of 3,800 tonnes per day at Pretium Resources Inc.’s (TSX, NYSE: PVG) Brucejack Mine in British Columbia are progressing on schedule, the company said Tuesday.
Additionally, the company said its initial observations from the third hole drilled as part of the 2019 deep underground exploration program continue to indicate that Brucejack-style mineralization extends at depth below the Valley of the Kings.
The company is undertaking mill upgrades that officials say are necessary to sustain processing at an increased production rate of 3,800 tonnes per day.
“The most significant upgrade is the shift from concentrate bagging to a bulk loading system,” the company said. “The bulk loading system is now installed in its permanent location and is operating as a fully integrated component of the concentrate process. Modifications to the flotation circuit, which include upgraded pumps and piping and an additional cleaning cell for the process circuit, will continue during regularly scheduled shutdowns as the final components are delivered.”
Underground development is accelerating to the targeted rate of 1,000 meters per month, with 993 meters achieved during June, the company continued. Development is expected to continue at approximately 1,000 meters per month for the remainder of 2019 to ensure development remains ahead of production requirements to achieve mining rates of 3,800 tonnes per day.
Meanwhile, the underground exploration program is continuing. Officials said a third deep hole, VU-2019, was added to the program to test both the extent of Brucejack-style mineralization and the porphyry potential directly below the Valley of the Kings deposit.
“The company’s ongoing 70,000-meter 2019 underground drill program is expected to improve reserve definition ahead of mining and to expand on the current mineral reserves at the Valley of the Kings,” Pretium said, adding that the first phase of the program is approximately 90% completed.
