| ABSTRACT: | Newcrest Mining Limited has updated its Mineral Resource and Ore Reserve estimates for the twelve month period ending 31 December 2016 and for this purpose, has completed a detailed review of all production sources. The review has taken into account updated long term metal prices, foreign exchange and cost assumptions, and mining and metallurgy performance to inform cut-off grades and physical mining parameters. The 100% Newcrest owned Telfer Gold Mine is located in the Great Sandy Desert of Western Australia, approximately 485km by road south-east of Port Hedland and 680km north-east of Newman. The mine has operated in its current two processing train configuration since the commissioning of both large scale grinding and flotation circuits in 2005. Gold and copper mineralisation in the Telfer Province is largely structurally controlled reefs, veins and stockworks hosted by deformed sedimentary rocks of Proterozoic age. Deep weathering depleted the copper in the upper parts of the deposits allowing historical gold production using gravity and cyanide leaching processes. Ore processing facilities now exploit the large gold and copper sulphide Mineral Resources using flotation to produce a copper concentrate containing elevated gold levels. A gravity circuit is used to produce a gold doré. Concentrate is exported to customers via Port Hedland. Small tonnages of oxide material are processed through the dump leach circuit. The Telfer operation is comprised of Telfer Open Pit (Main Dome and West Dome) and Telfer Underground (sub-level cave (SLC), M Reefs and Western Flanks selective mining). Open Pit mining is a conventional truck and hydraulic excavator operation. Selective mining techniques are used for excavation of the high-grade reefs, while stockwork ore and waste are mined using bulk methods (SLC). The limited quantities of near-surface oxidised stockwork are also bulk mined. Recent production is primarily from the Telfer Open Pits (Main Dome and West Dome), Underground sub-level cave (SLC) selective Underground M Reef mining and development ore from the Western Flanks. | |
