Processing Plant

De Simone was awarded the process plant bulk earthworks contract and activities are nearing completion.

Ground improvement works are completed and only punch listed items are outstanding. All areas have

been handed over to the engineering, procurement and construction (EPC) contractor for construction of

the processing plant.

Lycopodium, the process plant EPC contractor , mobilized to site in March 2022 and has made excellent

progress in advancing the critical path scopes for the plant. As of June 15, 2022, engineering activities

were 95 percent complete, procurement activities 78 percent complete and construction activities have

commenced in the following key areas:

• Civil and concrete works for the crusher, surge bin, milling and carbon in leach (CIL) areas

• CIL tank fabrication

• Installation of high security fencing

The delivery and installation of the SAG mill remains on the Project’s critical path and, despite supply chain

challenges and risks, is expected to be delivered to site on schedule. Manufacturing of core components

such as the shell, heads and trunnions and gear and pinion are well advanced. Despite challenges around

logistics due to global port congestion at the start of the year, key mechanical packages such as the

primary crusher and high-voltage transformers have started to arrive in-country in line with the schedule.

at the start of the year, key electrical packages such as the high-voltage transformers out of Shanghai have

started to arrive at site in line with the schedule. The 33kV tower erections are complete with transmission

line stringing commencing in June. Tower erections for the 90kV power line have commenced and the

first shut-down for tie-in to the electrical grid is scheduled for late July. The construction of the substation

is approximately 67 percent complete with all major equipment packages, such as control, automation

and communication panels, on-track for shipment in early July.
