The Murray & Roberts Mining platform is established in all major mining jurisdictions globally. The platform’s service offering spans the project life cycle, including feasibility studies, specialist engineering, vertical and decline shaft construction, mine development, specialist mining services such as raise boring and grouting, underground construction, contract mining and material handling solutions.

The Mining platform is engaged on projects in Australia, Indonesia, Mongolia, Kazakhstan, sub-Saharan Africa, Canada, USA and Mexico. These include 17 shaft sinking, equipping and shaft rehabilitation projects, 19 decline shaft and mine development projects, six production mining projects, 30 support and construction projects, and six major ore handling infrastructure construction projects. In addition, the platform has 28 raise drilling machines currently deployed on projects around the world.

Engineered Excellence defines our management approach at every level of the organisation. We thoroughly plan everything we do to achieve excellent outcomes, with nothing left to chance. We challenge ourselves to drive continuous improvement in project risk management and delivery, and in achieving industry-leading health, safety and environmental performance.


Strategic Quote

"We enable fixed capital investment that allows people to live better lives. We are both a service provider to society and an integral part of the socioeconomic ecosystem.

The strong rally in commodity prices, especially for future-facing commodities, has resulted in large cash surpluses for most mining companies. This is leading to forecasts of increased capital investment over the medium term.

While the near term remains somewhat uncertain, the forecast increase in capital investment over the medium term bodes very well for the Mining platform, offering a good opportunity to accelerate our growth, both organically and by means of acquisition."

Main Projects


The project scope is to construct the required infrastructure to transition the mine from an open pit to an underground mine. The sinking of two 1080 m shafts has been completed. The equipping of the production shaft is almost completed and shaft infrastructure development is underway. The decline ramp access system development continues and has progressed to approximately 570 m below the surface.


The project scope is to complete ore development, production ramp-up and contract mining for the first five years of operation. Challenges are still being experienced with the completion and de-bottlenecking of the existing underground and surface ore handling infrastructure, delaying the ramp-up of production. Despite these challenges, production rates have continued to ramp up during the year, albeit at a lower rate than planned.


The project scope is to sink a 1,000 m ventilation shaft. The shaft has advanced approximately 250 m from the collar on the surface.


This project is a cost-reimbursable contract to construct permanent surface facilities (winders, conveyors, headframe) and equip and line a shaft that is 5.5 m in diameter and 1,400 m deep. Engineering and procurement work is at an advanced stage and the project team has recently begun site preparations to start the work on site.


The project scope entails shaft construction, installation, operation, maintenance and support of rail chutes at the Grasberg Block Cave mine, as well as shaft operation, maintenance and production mining at the Big Gossan mine. Performance continues to be outstanding with the team consistently exceeding monthly targets.


The scope of work, to be undertaken by the GCR joint-venture is to construct the surface infrastructure, sinking and associated infrastructure for two large-diameter shafts and an underground crusher and ore flow infrastructure. This project has been severely impacted by the COVID-19 related shutdown, resulting in the client placing the shaft sinking projects on care and maintenance for the entire duration of the previous financial year. Shaft 4 sinking infrastructure is complete and commissioned, and sinking can begin as soon as work is allowed to resume. Shaft 3 sinking infrastructure construction will resume when the project restarts.
