Ausenco has been involved in Barrick’s gold processing operations at the Goldstrike Mine for nearly a decade.
Goldstrike is Barrick’s largest and most productive mining operation, with gold production of more than 40 million ounces since 1987. It is located on the Carlin Trend, approximately 40 km north-west of Elko, Nevada, USA.
Ausenco provided a scoping study, followed by a feasibility study for the Project, with the objective of improving the gold recovery process for double refractory ores processed in the Autoclave Facility. Subsequently, in 2011, Barrick retained Ausenco to provide the project management, detailed engineering (including engineering scopes of work for the construction packages), procurement, and expediting and logistics for the equipment supply; and dry and wet commissioning for the Project with support during ore commissioning. The initiative, known as the TCM (total carbonaceous matter) project, involved a $620 million investment that included major upgrades to the Goldstrike leaching circuits and new infrastructure.
Ausenco provided construction management services on site. We mobilised experts from our international offices and key members of the project team from our Vancouver office to lead a site team of approximately 60 people, mainly comprised of local hires from Nevada and neighbouring states.
The team managed a peak construction workforce of approximately 1,000 people, working for eight direct sub-contractors, to deliver earthworks; concrete works and protection; site tank fabrication; structural, mechanical and piping erection; and electrical and instrumentation installation. This project involved managing 65 procurement packages as well as 15 contracts.
Ausenco completed commissioning of the works prior to handover of the facility to the client for operation.
