MMG Ltd.'s third-quarter copper concentrate output rose 12% year over year to 97,369 tonnes due to increased productivity related to investment in new equipment at its Rosebery mine in Australia and to improved operations at the Las Bambas operation in Peru.
Copper cathode production for the period fell 11% year over year to 18,495 tonnes due to a weaker performance at the Kinsevere mine in Congo.
Production of zinc in concentrate increased by 19% on an annual basis to 68,628 tonnes in the quarter, mainly on the back of record quarterly production at the Dugald River mine in Australia.
The company said Oct. 17 that production of lead in concentrate slipped 4% year over year to 11,390 tonnes, while molybdenum in concentrate output was down 17% to 467 tonnes due to lower grades at Las Bambas.
Due to ongoing protests at Las Bambas, MMG said it expects 2019 copper production to be marginally below its guidance range of 385,000 to 405,000 tonnes.
The Peruvian government was recently reported to have authorized the armed forces and police to unblock access to Las Bambas after the company said it may have to cease production at the site.
