Context / scope of project :
An old underground base metals mine had recently been purchased by our clients. They found the previous owners had “cherrypicked” the high grade ore stopes without backfilling creating many geotechnical issues. As a result a stope had collapsed reducing production and impacting site morale.

The client wanted to fasttrack new levels of the mine and work through the geotechnical issues to sustainably increase production. In addition they wanted to embed in safety systems, attract and retain new staff and building its continuous improvement capability.

Achievements of PIP and Client:
	A fast and sustained return to pre-stope collapse production levels (6% increase in tonnes to surface versus baseline) despite ongoing geotechnical issues, reduced hoist availability and increased haul distances
	20% improvement in truck load factor
	38% improvement in production drill metres
	42% improvement in development metres
	9.3% improvement in jumbo availability
	5.2% improvement in loader availability
	6.3% reduction in ongoing costs
