The Young-Davidson gold mine is located near the town of Matachewan, approximately 60 km west of Kirkland Lake in Northern Ontario. Dumas has been onsite continuously since 2006, when we were tasked with dewatering and rehabilitating the mine’s shaft, and replacing the shaft furnishings. We also completed the installation of services, hoist installation, and rehabilitation of the headframe.
During shaft rehabilitation, Dumas also undertook a concurrent lateral development program that included portal construction, ventilation raises and associated mine construction. Dumas was tasked with undertaking a comprehensive and complete lateral development program to ore zones and ventilation drifts. This program involved the excavation of approximately 2,000 metres per year with peak targets at a minimum of 450 metres/month. Part of our responsibilities included developing the ramp from surface and driving in excess of 10,000 metres.
For a significant amount of time, Dumas undertook all raising on site which amounted to approximately 1,000 metres per year. We recently completed significant construction work in the Lower Mine.
