Commencement of Toll Milling Campaign for Granny Venn Open Cut Gold Mine
Resources & Energy Group Limited (ASX:REZ or the Company) are pleased to provide an update for Mining Operations at the Granny Venn Open Cut.
Toll Treatment for the first ore production from the Granny Venn Cutback operation has commenced. The initial metallurgical performance of the ore is highly encouraging. The unreconciled head grade of the mill feed is calculated to be 3.12g/t. This exceeds the forecast campaign head grade of 2.14 g/t. The gold milling campaign is being carried out at the Lakewood Gold Plant which is located at Kalgoorlie-Boulder and operated by Golden Mile Milling. Over the past month, the company has been progressively hauling ROM ore to Lakewood for crushing and preparation, refer plates 2 and 3.
The formal commencement of processing started on the morning of 18th. This followed after the weighing of dry carbon GIC (Gold in Circuit) samples for certification offsite by an independent laboratory. The milling campaign is being supervised by JT Metallurgical Services, with an independent Metallurgist also attending.
The operational plan for the first milling campaign comprises about 25,500t of ore which has been recovered primarily from the Granny Venn Ramp, and Granny Venn North Cutbacks.
The Cut-Back at the Granny Venn Ramp area is completed. The reconciliation in this area is substantially better than model with 157% of the tonnes being achieved for 132% of the ounces. Mining Operations in GV North and GV East are continuing, with emphasis on GV East which represents the main repository of ore, refer plate 1, which highlights the first High Grade Bench in the east cut.
The first gold pour is expected to take place early next week, which will include a combination of gold recovered from elution and gravity circuits.
