A surge in gold prices changed the calculus overnight. Scats material that had been written off as uneconomical to process was suddenly worth a second look — and with Evolution Mining's on-site recovery infrastructure already in place, reprocessing became not just viable, but urgent. The decision was made. Now it had to be executed.

But Evolution had the processing and recovery capability on site, not the crushing equipment needed to prepare the scats material. With rehabilitation works already underway across the site, a permanent solution was never on the table. Fixed infrastructure would have meant extended timelines, unnecessary land disturbance, and a costly demobilisation problem at the end of the campaign. What was needed was a mobile, modular crushing and screening solution that could be deployed quickly, operate within an active rehabilitation zone, and pack up just as efficiently once the job was done.

Mineral Processing Solutions delivered a fully configured mobile crushing and screening circuit on a dry hire basis — purpose-built for the demands of a hard rock application and designed to be on the ground and producing with minimal lead time.

The circuit comprised an Astec Kodiak K400+ cone crusher (modular), a Terex Magna MT620HR horizontal screen, three Telestack C2000W wheeled conveyors, a Telestack HF12 static hopper feeder, and a Telestack HF10F tracked hopper feeder. Together, the configuration provided adequate surge capacity ahead of the cone crusher, while the horizontal screening setup kept product sizing consistent and managed recirculation back through the cone — critical for maintaining throughput and quality across the campaign.

Being fully mobile and modular, the circuit slotted into Mt Rawdon's active rehabilitation environment without the footprint or commitment of fixed infrastructure. It was set up quickly, respected the site's land use constraints, and when the campaign wrapped, it demobilised cleanly — ready to be redeployed on the next job.

The numbers tell the story. MPS and Evolution Mining had agreed on an average throughput target of 160 tonnes per hour — a benchmark set to ensure the campaign was commercially viable. When MPS technicians were on site commissioning and running the plant, it was consistently performing in the mid-200 tph range. With Evolution Mining's own operators now at the controls, the circuit continues to average around 200 tph — well ahead of what was promised.

Beyond the tonnage, the real win is what this circuit unlocked. Material that had been stockpiled and written off is now generating revenue. The crushing and screening campaign has allowed Evolution to extract significant additional value from scats that would otherwise have gone to waste — turning a rehabilitation-phase liability into a commercial opportunity.

And the story doesn't end at Mt Rawdon. The mobile, modular nature of the circuit means the same setup can be redeployed on future applications — making this not just a one-project win, but a blueprint for how MPS and Evolution can continue working together.
