Round Oak approached us to assist with a solution that could maximise the ore recovery of stopes at their Bentley Underground Mine. 

To date, all the primary stopes have been extracted with minimal dilution observed, with extraction of the secondary stopes still to occur.

Achievements:

• Primary stopes have been extracted to full height, including the originally designed ore sill pillars. This represents an average 20% increase in ore tonnes on the initial design for these stopes
• Dilution within the consolidated rockfill sill has averaged less than 3%
