2 The Redpath Group Incorporated in 1962, The Redpath Group provides single source, comprehensive services to the North American and International mining industries. Technical and operational expertise, contribute to Redpath s reputation for practical and innovative performance resulting in the successful completion of sophisticated or technically complex mine development and construction programs. Redbore 40-S 22.5 o Blind Hole A combination of highly skilled personnel, far ranging experience and modern technology has made Redpath the driving force in mine construction world wide. Redpath Raiseboring Redpath Raiseboring, a division of J.S. Redpath Limited, the founding member of The Redpath Group, offers a full turn-key service from management consulting, operations personnel and service technicians. Whether small or large diameter openings, Redpath meets the demand for ventilation raises, production shafts, pilots for slashed and raised shafts, escape manways, fill raises, ore and waste passes and slot raises. With one of the most extensive fleets of raiseboring equipment in the world, Redpath leads the way in technology and experience. Technological advances, such as the introduction of volts per hertz drives to the industry, now becoming a standard in the manufacture of raisedrills, and the capability of semi and fully automated operation, combine to provide state-ofthe-art raiseboring.

Surface ventilation raise Meeting the Challenge.

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

Group and our industry and we take the necessary precautions for its protection.

17 Surface ventilation raise 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.

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).

In the Arctic, Redpath raisebored the first raise in permafrost and completed surface raises during February and March when temperatures reached -40ºC.

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.

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.

Approximately 15 850 m (52,000 ft) of raises were constructed without a lost-time injury. 2 103 m (6,900 ft) of 1.

18 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 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 m (2,222 ft) of 3.05 m (10 ft) diameter. A Canadian record for longest single pull. In Manitoba 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 m (52,000 ft) of raises were constructed without a lost-time injury m (6,900 ft) of 1.07 m (42 inches) diameter raises were constructed in an 11-month period.
