Meekatharra Gold Operations (MGO)
MGO comprises the Bluebird CIP plant (1.4 – 1.8 million tpa) and associated infrastructure and is the processing plant for the northern part of the Central Murchison Region.
During the half-year, mining occurred at the Paddy’s Flat and South Emu underground mines. The portal and decline for the Bluebird underground mine commenced late in the half with an expectation to be driving the first ore by the end of the next half. Open pit mining occurred at the Mickey Doolan, Five Mile Well and Sabbath open pits with the latter two being predominantly in early stages with waste pre-stripping capitalised.
Crushing plant throughput was significantly improved with the commissioning and successful operation of a new secondary crushing circuit in August 2019. Operational output was impacted by a major disruption (20 days) due to the failure of the SAG Mill bearings during October 2019, however, the higher plant throughput with the new secondary crusher offset these losses resulting in a reduction in processing unit costs.
