Construction and development continues on schedule for commissioning of the underground mine in mid-2017.
Following the full enclosure of the mill building in October, internal construction has progressed significantly. Over 45% of the internal structural steel is now complete and concrete continues to be poured and is over 80% complete. Concrete is currently being poured in the gold recovery area and the truck drive through bay. All major equipment continues to be delivered according to schedule including the flotation concentrator which is now on site. Flotation tanks and tailings thickener are being assembled and the process and fire water tanks have been installed. The SAG and ball mills sole plates are now in place and grouted and ready for mill shells installation. SAG mill bearing housings have been installed. Transformers have been installed within the mill. Electrical and mechanical contractors are now on site, and electric and piping installation has been initiated in the mill and underground.
The 330-person camp which includes mine dry, offices, recreation facilities, dining hall and kitchen is substantially complete and fully operational.
The transmission line construction continues to progress towards completion. All of the towers are in place and the first 42 kilometers of the 57-kilometer transmission line is now energized to the Knipple substation. The first of the three wire conductors of the final 15 kilometers have been strung and the second is approximately 60% strung. The transmission line is expected to be fully energized early next year, ahead of when it is required for mine commissioning. An additional six diesel generators have been delivered to site and three of the six generators are fully commissioned. The generators will provide more than adequate power to maintain full mill and underground production in the event of any transmission line failure.
The main portal access for the Valley of the Kings has broken through to surface and the steel structure of the portal building is under construction. The portal will serve as the primary access point to convey the gold ore from the underground crusher to the mill.
Underground development remains on schedule and crews are advancing at an average rate of over 30 meters per day. Excavation of the major infrastructure is now complete including the crusher and transfer area. The third and final vent raise has broken through to surface. Underground work is focused on continued ramp and level development with seven mining stopes now accessible. Concrete and slab installation for the underground crusher and transfer tower continue to progress. Approximately 30,000 tonnes of ore has been stockpiled in preparation for mill commissioning expected to start in mid-2017.
