In a remote island in Papua New Guinea, Misima Island hosts a large historical gold reserve. Kingston Resources is restarting the operations and Stellen has completed water management and services design for the new mine infrastructure area, pit dewatering, and an overall mine water balance.

With five metres of rain per year, and two existing 5.5GL pits full of water, it is one of the most complex water problems to solve. Rather than treating and disposing of the existing pit water, our design includes its transfer and reuse for raw and process water.

Northparkes Mines operates a copper/gold mine near Parkes NSW. E48 was a new block cave project which included a new crusher, materials handling system and extraction level infrastructure. A Stellen engineer led the design, construction and commissioning of the extraction level infrastructure.

Because of financial staging, most of the project was implemented after mining operations had commenced. This meant careful planning and coordination (and negotiation) to conduct an expansion project in a live operating environment. The project was completed ahead of schedule.

On this $1.6bn open-cut expansion, Stellen engineer, Logan completed the site water balance and water management design. His work included design of the pumping systems, controls, and preparation of the water management system functional specification.

Ian managed the construction-phase design, procurement, and delivery of the upgraded MIA for buildings, services and the new fuel facility. The delivery required resolving a wide range of civil and related design challenges including: design optimisation based on procurement strategy; services coordination (power, water, sewer and stormwater).
