Whitepaper Shows Production Optimiser Reduces Dilution By 62% at Cracow

A newly released whitepaper, co-authored by Evolution Mining, details a comparative study undertaken at their Cracow gold mine in which stopes drilled using Minnovare’s new ‘Production Optimiser’ technology, recorded 62% less average dilution than stopes drilled using the existing technology/process (11.7% overall dilution, compared to 29.8% respectively).

The whitepaper contains detailed survey and stope performance data taken during the first six months following the Production Optimiser’s implementation at Cracow. The authors go on to discuss the significant positive implications for future mine planning, resourcing and profitability.

The Authors stipulate that if an equivalent reduction in dilution were applied to Cracow’s full year FY17 production data, all things remaining equal, an additional $8.2M AUD of ore would be recovered, with a $4.5M AUD reduction in costs associated with dilution (haulage and processing).

Minnovare credits Evolution Mining as a key development and implementation partner of the new technology, which amongst other advances, significantly improves blast-hole drilling accuracy – thereby reducing hole deviation, a significant contributing factor to dilution.

The new technology can be implemented on sites running any rig make/model and works independently of the rig’s on-board systems. The Production Optimiser’s software interface, Minnovare CORETM, syncs directly with mine-planning software and features digital drill plans and plods – helping ensure that “what is drilled is what was designed" by facilitating greater data capture and visualisation between rig operators and engineering/technical crews.

Minnovare Managing Director Callum McCracken; “From day one the team at Evolution Mining have showed great confidence in Minnovare and the new technology. They were integral to the early development of the system in 2018 and we’re pleased to see the Production Optimiser delivering value for them so soon.”

Evolution Mining’s Phil Jones: "Aside from improving average stope performance, the Production Optimiser has provided us with greater reliability moving forward. With less overall dilution we’re also seeing less variation in dilution across stopes. We now have the confidence to set more ambitious targets, by considering new mine plans and blast patterns that would previously not have been considered."

Minnovare and Evolution Mining will be co-presenting the new whitepaper at a number of events in Australia and overseas in the coming months. To find out more contact Minnovare via the website:
