Mammoth gold mine project starts mill commissioning
Northern Ontario Construction News staff writer
Detour Gold Corporation reported in November that the mining and construction progress of its 100 per cent owned Detour Lake open pit gold mine in northeastern Ontario is proceeding on schedule with first gold pour expected in January 2013.
Mill commissioning activities for the first production line are underway and it is expected that the first ore will be fed through the mill circuit before year-end, the company said in news release.
Detour Lake development highlights:
- Gold production to start in January 2013;
- Project construction reached 95 per cent completion mark at end of October;
- Mill commissioning of first production line commenced in October;
- Average mining rates above 100,000 tpd during September and October;
- Ore stockpile totalled 1.1 million tonnes at end of October;
- Operational team now at 396 employees, ahead of schedule.
“We are nearly finished with construction and I am proud of what our team has accomplished in just 24 months,” said Detour Gold president and CEO Gerald Panneton. “The energy at site is vibrant and I would like to thank all our employees and contractors for their dedication and excellent work. We are now confident we will see the first ore in the mill circuit before year-end, almost two months ahead of the original schedule. The first gold pour is expected to occur in January 2013 and will mark a new chapter in Detour Gold’s successful history as it transitions from a developer to producer and becomes the next mid-tier gold producer in Canada”
Construction progress was at the 95 per cent completion mark at the end of October 2012 and the Detour Lake mining operation is nearing its first gold production, the company said. At the processing plant, the mechanical work is 98 per cent complete, which has permitted commissioning activities to commence. Mechanical alignment of the SAG and ball mill for the first grinding line is complete. Contractor manpower has begun to ramp-down and efforts are now focused on finishing the electrical and instrumentation work.
The first cell of the tailings management area (TMA) has reached the dam level required for the 2013 operation. Dewatering of the historic Campbell pit to the TMA is progressing as planned and will reach the targeted water level well in advance of operations. The water recovery system, the tailing lines and secondary containment systems are essentially complete.
