Project Overview / Description

MMG have engaged the services of CivilPlus Constructions to construct a refrigeration cooling plant at the Dugald River Mine. The site is in the Knapdale Ranges approximately 85km north-east of Mt Isa and 65km north-west of Cloncurry in north-western Queensland. Dugald River is 100% owned by the MMG Limited and is one of the world’s top 10 zinc operations. The operation predominantly produces zinc concentrate, with by-products including lead and silver. A large refrigeration cooling plant is proposed for Dugald River to allow for further expansion and progression of the underground mining activities.

The scope is divided into three different components to reflect the different engineering and construction disciplines required to complete the project, namely:

• Civil
• Mechanical
• Electrical

CivilPlus Construction was commission to deliver the Civil component of this project.

The project scope was to construct a refrigeration cooling plant at the South Fresh Air Riser (FAR) and a bulk air cooler at the North FAR. The South and North FAR are approximately 600 m apart. CivilPlus Construction’s detailed scope was to deliver rock breaking, earthworks, pavement works, pipe works, conduit works and concrete works at the South and North FAR.

Construction works began in late March 2021 and are expected to be complete in mid August 2021.
