5/2 Roster | Residential Based | Expression of Interest

Project engineering leadership and execution oversight for the Mt Lyell restart

Mt Lyell is an iconic asset that has helped shape Australian mining for over 120 years. Today, it’s poised at the start of its next chapter, which consists of large-scale brownfields restart project, delivering an operation that will support the growing global demand for copper as a critical energy transition metal, with significant gold and silver by-products.

Sibanye-Stillwater Australia has completed the studies necessary to support the restart of operations, consisting of underground mining, the construction of a new processing facility, a paste backfill system, shaft infrastructure refurbishment, and all the other required non-process infrastructure at Mt Lyell.

Expression of Interest
The Project is still subject to final Board approvals, so we are seeking Expressions of Interest for a Senior Project Engineer to support safe, timely and cost-effective delivery of the Mt Lyell Growth Project.

Location of Role
The role is intended to be based on site in Queenstown, Tasmania, and a residential arrangement is strongly preferred. Alternative arrangements may be considered for an exceptional candidate, provided they can maintain regular site presence and close engagement with the project team.

About the Opportunity
Subject to Board approval, this role will support the Project Director in the safe, timely and cost-effective delivery of the Mt Lyell Cu-Au Growth Project while providing independent oversight of project progress, performance and execution readiness.

The role will coordinate project engineering activities across design, procurement, construction and commissioning interfaces, act as the Project Director’s delegate as required, and lead earned value management, quantity verification, progress assessment, forecasting and project controls assurance.
