BRITISH COLUMBIA – Thompson Creek Metals of Denver said that mill throughput averaged 52,457 t/d during November at the Mount Milligan copper-gold project 145 km northwest of Prince George. That is a significant increase from the 44,077 t/d average during Q3 2015. The upturn comes thanks to the installation of a second SAG discharge screen deck in late October.
Newcrest Mining provided the quarterly report. Gold production was 27% lower than the prior period mainly driven by lower mill throughput rates at Cadia, Lihir and Telfer. It has not experienced any material COVID-19 related disruptions to production or to the supply of goods and services.
Historically the ball mill has typically operated within a 12-13MW power draw range and well below the 15MW mill design. Changes to the milling circuit configuration to increase power draw to the design capability of the ball mill forms part of the programme to lift process plant throughput rates towards a targeted 10mpta2.
