Mining Activities
During the Quarter, mining activities focused upon ore feed blending for the processing plant and the completion of Stage 2.2 construction of the Mining Waste Facility (MWF), which was achieved in September.
A total of 789,413 bank cubic metres of material was moved during the Quarter, with the ore grade averaging 0.21% WO3 and 0.03% Sn. The improvement in the processing plant performance continues to inform the blending strategy on optimal ore feed quality for throughput and recovery. This will continue to be reviewed as further processing plant improvements are made, particularly in relation to the gravity fines circuit.
Following the resource definition drilling program, the mine plan has also been updated for a further intermediate pit design to optimise the short and medium term strip ratio and improve project cashflows. In addition, further investigations are underway on pre-processing opportunities to enhance the ore feed quality as part of the Company's continuous improvement initiatives.
