PT Redpath Indonesia says it achieved yet another milestone in November 2022, when the first ever Redbore 90 EX large diameter raisebore was successfully commissioned. The commissioning followed the large diameter contract awarded to PTRI earlier in the year.

It said the historic achievement was the culmination of a very demanding and concerted effort by Redpath’s teams in Canada, Australia, Indonesia and South Africa.

The most recent addition to Redpath’s fleet at PT Freeport Indonesia, the Redbore 90 EX, provides the ability to establish 5 m and 6 m diameter raises over distances more than 300 m in length. This meets the client’s expansion requirements in both ventilation and ore movement demands.

PTRI currently maintains and operates a fleet of 12 raisebore machines at PTFI, drilling out a variety of holes for different applications, ranging from drain holes of various diameters, intake ventilation raises, slot raises, exhaust raises, and ore passes. The addition of the Redbore 90 EX makes PTFI the mine with the single largest Redpath raisebore fleet at one site.
