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.

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-of-

the-art raiseboring.

Through its ability to complete raiseboring

assignments under difficult or unusual

conditions, Redpath has developed skills and

experience that are indispensable for clients

considering raiseboring projects of any scope.

The development of the Redpath Redbore

raisedrill is one result of innovation born of the

determination to meet specific challenges and

fill the clients needs. From the original Redbore

40 to the Redbore 100, Redpath Manufacturing

is pleased to present its Redbore family of

raisedrills.

Contracting experience combined with

manufacturing and service capabilities enable

Redpath to provide a level of service

unparalleled in the industry.

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.

To provide the mining industry with a level of service

that will exceed normally accepted standards is the

philosophy applied on all Redpath projects.

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.

As Redpath faces the challenges of the future, our

commitment to safety, quality and the environment

will continue.

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.
