This course is our most popular program because of the face to face contact which allows learning from other attendees as well as from the Facilitator. This Diploma is also the minimum educational requirement to obtain a WA Quarry Managers Certificate of Competency. We are currently scoped for the latest 2021 release, coded RII50120. The training is undertaken in three blocks: Block 1: five mining units, Block 2: five management units and Block 3: three mining units.
