Work on the course ore stockpile reclaim tunnel is near completion.

Construction work on the five bay truck shop building which is attached to the existing admin / warehouse building has gone exceedingly fast as the contract was awarded only eight weeks ago. As shown in the photo below, the truck shop is now fully erected with exterior cladding and overhead cranes ahead of schedule.

Grinding mills and major mill equipment is currently being received at the mine site and will be installed and tested inside the completed buildings during the winter.

The Company's mobile mining fleet is currently being utilized by assisting with construction activities surrounding the installation of an overland conveyor system that will move crushed ore from the newly constructed primary crusher to the course ore stockpile located behind the concentrator building.

Preproduction mining activities are scheduled to start once the Company's main loading unit, a Komatsu PC8000 (53 yard capacity), has arrived on site. This large hydraulic shovel is on route from Germany and is expected to be on site by mid September and fully assembled and operational by mid October 2010. The second half of the mining fleet, including a second PC8000, is scheduled to be on site by April 2011. Preproduction mining will start in the Pit 3 area with a push-back on the western wall. A total of 24 million tonnes of material is scheduled to be moved prior to the mill startup in May of next year, while on average a total of 55 million tonnes of material will be moved in a full production year.
