Welcome to Raisebore Australia
Raisebore Australia Pty Ltd is a private company, wholly owned by its Founder and Managing Director, Mr Rod Bertram.
The company was formed early in 1994 by a management buy out of the Raiseboring Division that Rod had established in 1992 for a leading Diamond Drill Contractor. This Division comprised only two raiseborers, and the concept of down-reaming was introduced into the Australian market place at Mount Isa Mines in 1992, utilising one of these machines.
