PHQ's new Vibration Dampened Jackleg Control Handle was developed in partnership with Université de Sherbrooke and CANMET-MMSL at the request of SOREDEM and funded by several major Mining Companies and Le Institut de Recherché Robert-Sauvé en Santé et en Sécurité du Travail (IRSST). PHQ and CANMET featured the new handle at CIM2006 in Vancouver, at PDAC2006 in Toronto and will demonstrate again at CIM2007 in Montreal. Testing has been completed at IamGold - Mouska, WestDome - Kiena, Agnico Eagle - Laronde, and IamGold - Sleeping Giant in Quebec as well as GoldCorp - Hoyle Pond Porcupine Joint Venture in Ontario. The test results have proven the anti-vibration handles reduce damaging vibration at the operators hand by 60 percent and the handles were well received by drill operators. The handle is built to be durable and requires no more maintenance than standard handles. The first production run of 75 handles was completed March 16th followed by a second run of 125 handles completed in mid-April 2007. The anti-vibration handles will replace standard backheads and handles in existing fleets of Secan 250 and Canun 260 drills. Over fifty handles now out on test.
