Didipio Project Construction Progress

Construction activities at the Didipio Project have continued to progress to schedule as the project now moves into the final stages development. Approximately 1600 workers are engaged on the project with 98% of these being Filipino nationals. Demobilization of the earthworks and concrete contractors is expected to start next week as these disciplines of work are substantially complete.

The initial lift of the Tailings Storage Facility (TSF) is now completed and piping to and from the TSF is also nearing completion with the return water line already in service. Power lines are now being installed to the TSF (Figure 2). Additional lifts to the TSF will be built over the next six years in conjunction with ongoing operations to expand the facility to its full Life of Mine capacity.  

Construction activities at the process plant are now focused on completing the piping and electrical work. Structural and mechanical works are 95% complete. Vendor representatives are now at site assisting with equipment testing and pre-commissioning. Belts are presently being installed on the conveying system (Figure 3).

More than 80 electricians are pulling and terminating electrical cable throughout the process plant. Substantial completion of the electrical work for the process plant is expected by the end of October at which time we plan to energise the mills and commence pumping water through the process plant.

All reagents and media have been delivered to site and 85% of the inventory of plant spares/first fills are also in storage at Didipio. Recruitment of the senior operations managers is complete and the current focus is on ramping up the operator training programs in preparation for commissioning of the process plant.

The mining contractor is taking delivery of the larger haul trucks and excavators to complement the current equipment at site. This will continue through to Q1 2013. Mining continues to ramp up (Figure 5) and now that stage one TSF construction is complete, the focus has shifted to ore mining and delivery to the ROM pad which commenced last month.

The Company expects to commence processing ore through the mills in November.  Capital costs for construction remain in line with the revised capital cost of $220 million, which was released in July this year.

Community & Environmental Activities

Training programs are well underway in preparation for operations. Once operations reach a steady state, we expect approximately 1,000 employees and contractors employed on roster at the Operation. The majority of these workers come from local and surrounding communities in Nueva Vizcaya and Quirino provinces.

Reforestation initiatives continue to be an area of focus with eight local barangays entering into a Memorandum of Agreement to establish 40 hectares of reforestation plantations. A local cooperative at the nearby community of Dibibi has also been formed which is now advancing plans to establish a 100 hectare commercial tree farm in partnership with OceanaGold and a private company.

Various infrastructure improvements have been undertaken with farm to market roads upgraded, clean water systems in Barangay Tucod completed, as well as construction of classroom expansions for nearby communities in Didipio and Alimit.
