Western Australia’s mining sector has long been defined by production, scale, and commodity cycles. Increasingly, however, a quieter shift is underway - one that is reshaping how operators think about performance: maintenance capability.
As assets age, operations expand into more remote regions, and production expectations remain high, the ability to maintain fixed plant efficiently is becoming a defining factor in operational success. What was once considered a support function is now moving closer to the centre of strategic decision-making.
Kalgoorlie-Boulder-based mechanical engineering company OHLMEC reflects how this shift is playing out in practice. Founded in 2022, the business has scaled rapidly to a workforce of up to 100 personnel, delivering fixed plant maintenance across mining, quarrying, and processing operations throughout Western Australia
According to director Jesse Ohl, the growth is not simply a result of increased activity, but a sign of changing expectations across the sector.
“We’re seeing consistent demand for reliable, skilled maintenance teams, particularly in regional WA,” he said
For operators, the cost of downtime continues to rise - not only in lost production, but in the flow-on effects across tightly scheduled operations. In this environment, responsiveness and reliability are becoming key commercial differentiators for service providers.
“In our line of work, downtime is critical. The ability to mobilise quickly and deliver quality outcomes is where real value sits,” Mr Ohl said.
This is particularly relevant in regions such as the Goldfields, where distance, workforce availability and logistics amplify operational risk. Maintenance providers are increasingly expected to integrate seamlessly with site operations while maintaining consistent delivery across multiple locations.
At the same time, labour constraints remain one of the sector’s most persistent challenges. Skills shortages across mechanical trades are forcing businesses to rethink how they attract and retain talent, with greater emphasis on long-term workforce development rather than short-term recruitment solutions.
OHLMEC has prioritised apprenticeships, training and cultural alignment as part of its growth strategy - an approach that mirrors a broader industry shift.
“We’re not just looking to fill roles. We’re building a workforce that can support the business as it scales,” Mr Ohl said.
That scaling, however, is being approached deliberately. While the company is expanding beyond its Goldfields base into other parts of Western Australia, the focus remains on controlled growth and maintaining service quality.
“We’ve built a strong foundation locally. Expanding is important, but it has to be done in a way that protects what we’ve built,” he said.
The broader implication for WA’s mining sector is clear: as operations become more complex and geographically dispersed, maintenance capability is no longer a background consideration - it is a competitive lever.
Companies that can deliver consistent, high-quality maintenance at scale, particularly in regional environments, are increasingly positioned not just as service providers, but as critical partners in operational performance.
