Meeting the Challenge

... is the guiding principle by which Redpath operates and we endeavour to make every Redpath job a safe one. Everyone at Redpath has a responsibility to each other and themselves to work safely.

A quality product from concept to completion is the result of this commitment.

We believe that respect for our natural environment is paramount to the success of The Redpath Group and our industry and we take the necessary precautions for its protection.

To provide the mining industry with a level of service that will exceed normally accepted standards is the philosophy applied on all Redpath projects.

As Redpath faces the challenges of the future, our commitment to safety, quality and the environment will continue.

Surface ventilation raise

Project Highlights

In the mountains of Irian Jaya, Indonesia, Redpath has worked continuously since 1981, and has excavated raises inside adits at an elevation of 4 100 m (13,451 ft). Access to the mine and raise drill sites was either via the largest single span cable car tram in the world or by helicopter. In the Arctic, Redpath raisebored the first raise in permafrost and completed surface raises during February and March when temperatures reached -40ºC. Access to these projects for machinery, personnel and supplies was primarily by aircraft. In Northern Ontario - Constructed a 3.96 m (13 ft) diameter raise by 646 m (2,120 ft) long. A new Canadian record for largest by volume. In Northern Ontario - 677 m (2,222 ft) of 3.05 m (10 ft) diameter. A Canadian record for longest single pull. In Manitoba - 285 m of 5.1 m (16.6 ft) diameter. A Canadian record for largest diameter set. Completed in excess of 43,000 ft of raises in one year (1999). Directionally drilled a 1,349 ft pilot hole with a total deviation of 1.7 ft off target. A North American record for the longest directionally drilled hole with a raisedrill. On one property, between 1985 and 2000, Redpath constructed all slot raises, manways and ventilation raises with a Redbore 40-S. Approximately 15 850 m (52,000 ft) of raises were constructed without a lost-time injury. 2 103 m (6,900 ft) of 1.07 m (42 inches) diameter raises were constructed in an 11-month period.
