The CMGP is located in the Murchison Goldfields of Western Australia around the regional towns of Cue and Meekatharra. The CMGP project strategy has a number of current and proposed underground mines and open pits being developed over time. After a refurbishment, integration of assets and completion of an initial development strategy the project started in the second half of 2015 with the plant commissioned in October 2015.
CMGP has a nominal 2.0 million tonne-per-annum CIP gold processing plant and associated infrastructure, with a significant number of historical open pit and underground mines. The consolidation of the Meekatharra Gold Operation the Nannine Project tenements and recently the Comet Project increased Westgold’s Mineral Resource base in the district to its current level of 7.7 million ounces. The acquisition of the Meekatharra assets provided the opportunity for an expanded CMGP to commence production in October 2015 with an initial 12-year mine plan.
Mineral Resources and Ore Reserves
At 30 June 2016 the CMGP had the following Mineral Resources and Ore Reserves:
• A Measured, Indicated and Inferred Resource of 108.7 million tonnes at 2.21 g/t gold, containing 7.7 million ounces of gold; and
• A Proved and Probable Reserve of 22.8 million tonnes at 2.63 g/t gold, containing 1.9 million ounces of gold.
The overall CMGP has for the first time consolidated all the major historic gold mining centres in the Central Murchison region. These have an aggregated gold production history of approximately 10 million ounces. These include the Day Dawn, Cuddingwarra, Big Bell, Reedy, Nannine, Yaloginda, Paddy’s Flat and Meekatharra North gold mining centres. Within these the dominant historic production was sourced from a handful of larger underground mines, namely the Big Bell Mine, the Great Fingall and Golden Crown Mines (at Day-Dawn), the Triton Mine at Reedy’s, and the Fenians Mine at Paddy’s Flat. With the exception of Big Bell and Golden Crown, none of these have been subject to modern mining and the re-invigoration of all these mines to again become long-term and sustainable gold producers is a key objective of the CMGP’s long-term strategy.
