Drill optimiser cuts Cracow dilution

A TRIAL of Minnovare’s Production Optimiser technology at Evolution Mining’s Cracow gold mine in Queensland has recorded 62% less average dilution than stopes drilled using the existing technology and process.

Minnovare's Production Optimiser on a rig at Cracow.

The Production Optimiser led to 11.7% overall dilution as compared to the old ways that had 29.8% overall dilution.

If an equivalent reduction in dilution had been applied to Cracow's full 2016-17 financial year production data another $8.2 million of ore could have been recovered with a $4.5 million reduction in the haulage and process costs associated with dilution.

The Minnovare technology helps improve blast-hole drilling accuracy, which helps reduce hole deviation, a contributing factor to dilution.

The technology can be implemented on any make or model of rig and work independently of the rig's onboard systems.
