GR Engineering to design and construct OZ Minerals’ West Musgrave process plant

Posted on 14 Apr 2023

GR Engineering Services says it has entered into two contracts with OZ Minerals Musgrave Operations Pty Ltd, a wholly owned subsidiary of OZ Minerals Limited, for the design and construction works of the West Musgrave mineral processing plant in Western Australia.

GR Engineering has been engaged by the company to provide the following services for the West Musgrave project:

  • Engineering design, drafting, project management and commissioning; and
  • Structural, mechanical, piping, electrical and instrumentation construction works.

GR Engineering’s wholly owned subsidiary, Mipac Pty Ltd, will also be engaged within the GR Engineering scope of work to provide specialist electrical and instrumentation services.

The estimated revenue from the delivery of these contracts will be A$312 million ($211 million) over a two year period.

Tony Patrizi, Managing Director of GR Engineering, said: “We are pleased to have been engaged by OZ Minerals to play a key role in the delivery of the world- class West Musgrave project. This is an important project for GR Engineering as we have worked with OZ Minerals over many years on projects within the OZ Minerals group, including the West Musgrave project, and see this award as a strong endorsement of our proven delivery capabilities.”

Debbie Morrow, Projects Executive for OZ Minerals, added: “We’re delighted to be working with GR Engineering on the design and construction of the minerals processing plant for the West Musgrave project, which is set to be one of the largest, lowest cost, lowest emissions copper-nickel projects.”

The West Musgrave project feasibility study the OZ Minerals Board signed off last year details a 13.5 Mt/y operation with average production of circa-28,000 t/y of nickel and circa-35,000 t/y of copper over a 24-year operating life.
