Three completely different types of ore deposits demand 'fit for purpose' mining methods. We consider the move in the last 20 years to ‘super’ block caving, unlocking massive deep resources, then change scale and examine an innovative new technology that enables ‘surgical mining’. Lastly, changing the mining method for Cobre's project in the Kalahari Copper Belt, Botswana, to in-situ leach may unlock new potential for the region.
We start with a look at block caving to consider the benefits and challenges of working in large deposits at greater and greater depths. We talked to Katrina Crook a mining engineer, currently with Glencore where she is Lead - Governance & Integration, Value Realisation. Her diverse experience provides provides a great overview of how the method works, the importance of geological knowledge and expertise and the challenges that need to be overcome.

In our next story we consider a completely different mining challenge and change the scale of the target. Allan Cramm is the VP Innovation for Novamera – a technology company with a new approach to mining, finding ways to unlock value in high grade narrow zones by using ‘surgical mining.’ They are employing a large diameter drill in conjunction with an innovative sensor technology and software to mine a range of targets that previously would have been stranded.

Lastly - what do you do when you the high grade, underground mining target eludes you, but what you discover is too deep for an open pit? In the case of Cobre, an Australian listed company, they recognized an opportunity for an in-situ copper recovery operation. We talked to their CEO, Adam Wooldridge to find out the story behind the discovery and their plans going forward.
