VANCOUVER (miningweekly.com) – Canadian zinc miner Trevali Mining expects to produce 140% more zinc this year, following a transformational 2017 that saw it produce a record 177.4-million payable pounds of zinc.
The 2017 output was boosted by the December quarter production from the newly acquired Perkoa mine, in Burkina Faso, and the Rosh Pinah mine, in Namibia, which it acquired from Glencore on August 31. Production for the assets from April 1 to August 31, was treated as part of the working capital adjustments captured in the purchase price calculation.
Trevali, which is based in Vancouver, on Monday reported record unverified fourth-quarter production of 104.8-million payable pounds of zinc, 13.5-million payable pounds of lead and 396 899 oz of payable silver. Preliminary 2017 output was reported at 45.8-million pounds of lead and 1.6-million ounces of payable silver.
Consolidated output was helped higher by sterling performances at Trevali’s Perkoa and Caribou (Canada’s New Brunswick province) mines. At Rosh Pinah, the mill re-grind circuit was completed during the fourth quarter and is expected to boost recoveries and increase concentrate quality going forward.
Meanwhile, at the Santander mine, in Peru, Trevali completed an upgrade to the underground water pumping infrastructure and this is expected to reduce the electricity requirements and improve overall mine safety as mining digs deeper below the water table.
