The Donkin Mine is currently permitted for run-of-mine annual production of 3.6 million tonnes, which would produce approximately 3.0 million saleable tonnes after being washed in the onsite coal handling and preparation plant.
There are currently two surface portals to the existing two subsea tunnels which extend approximately 3.6 km from the Donkin Peninsula to intersect with the Harbour Seam.
Infrastructure:
- twin, 7.6 m (25 ft) x 3.6 km (2 mi) access tunnels in place.
- private coal haul road for portion of truck route to Sydney, Cape Breton.
In March, 2020, Kameron announced that it was ceasing production operations at the Donkin Mine due to adverse geologic conditions.
Before idling the Mine, Kameron was in the Development Phase of the operation where two coal sections (each containing two continuous miner units) were actively developing the Mine’s main underground infrastructure and the first production panel to allow for the long-term and highly active Production Phase, which would incorporate retreat mining. For the retreat mining phase, Kameron was evaluating the viability of installing a longwall mining system which would have reduced its operating costs and significantly increased production volumes.
Remaining rehabilitation work underground was completed early in 2017, and the mine transitioned into production, with the first coal extracted on February 27 that year. Development of underground wor ........
