The company aims to achieve this through implementing a grade control program as well as developing an optimised mine plan . The company has been unable to realise the mine's full potential due, in a large part, to the lack of consistent grade control of mate- rial entering the mill after being mined in the pit . Management is limiting daily production to the capacity of the 6000 tonnes mill as it con- tinues to work on implementation of its grade control program and development of an opti- mised mine plan . Songjiagou is Majestic's flagship project. The company began commercial production in May 2011. The company's joint venture partner, Yantai Dahedong Processing Com- pany Ltd, has held the contract to mine and process ore since start-up . There were 442,331 tonnes milled for the three months ended March 31, 2016, with an average head grade of 0 . 44 grams/tonne (g/t), compared to 364,232 tonnes milled, with aver- age head grade of 0 . 42 g/t, for the comparative period of 2015. Majestic estimates the average head grade will continue to be in the range of 0 . 45 g/t until the grade control program and optimised mine plan are in place . Total gold produced for the March quar- ter was 5498 ounces, compared to 4807 ounces for the comparative 2015 period . The company expects production to continue to average around 5000 ounces quarterly until it has fully implemented the optimisation pro- grams . Gold produced for the six months ended March 31, 2016, was 12,711 ounces, com- pared to 9871 ounces for the comparative period . The increase can be primarily attribut- ed to the recovery and processing of approx- imately 30,000 tonnes of fine fraction material of a higher grade than the overall grade of ore throughput to the mill . Songjiagou has three processing plants. Two were put into operation in 2006 with daily capacities of 200 tonnes and 1200 tonnes and the third in May 2011 with a capacity of 6000 tonnes . The 1200 tonne mill is not being utilised and all material mined currently is pro- cessed in the 6000 tonne mill . In 2015, the 200 tonne mill was upgraded to 2000 tonnes by a third party, YE Zhifan, to process waste material . Zhifan has paid all up- grade costs and pays CNY5 . 5 per tonne for use of the tailings dam to a daily maximum of 1500 tonnes .
