Mine Life30 years (as of Jan 1, 2022)
Donkin Coal Mine is the only operating subsea coal mine in the world and Nova Scotia’s only operating underground coal mine.

September 13, 2022 - Kameron Collieries ULC has received regulatory approval to reopen the Donkin Coal Mine from the Nova Scotia provincial government. Production has resumed. The Mine had been on care and maintenance since March 2020.

The mine’s current industrial approval expires on December 4, 2022. The company applied for an industrial approval renewal on September 6, 2022, and the Department of Environment and Climate Change is required to make a decision within 60 days of a completed application.

Summary:

The Donkin Coal Project area occurs within the Sydney Coalfield of Nova Scotia, a large coal basin of Carboniferous age that extends north and northeast from the northern part of Cape Breton Island under the Atlantic Ocean towards Newfoundland.

Up to 11 coal seams are recognized in the Donkin area, and three of those may have potential for eventual underground extraction: Lloyd Cove, Hub and Harbour seams (in descending stratigraphic order).

All coal resources reported within the Donkin Lease fall within the underground category. There are no resources suitable for surface mining. Coal resources that are deeper than 700 m rock cover are present at Donkin and would be classified as nonconventional at this stage. Non-conventional resources have not been included in this resource statement. Sterilized resources are those that are unavailable for mining due to environmental or other restrictions. At Donkin, coal within 75 m of an offshore drill hole that intersects the coal seam in question is unable to be mined. For a 2-m thick seam, this equates to approximately 50,000 tonnes of coal. For the three potentially mineable seams, Lloyd Cove, Hub and Harbour, approximately 1.3 million tonnes (Mt) of coal would be sterilized by this legislative requirement. In addition, seams under less than 200 m of solid rock cover were not considered for longwall mining. An estimate of in-situ resources of coal in the three seams where the rock cover is between 100-m and 200 ........

Summary:

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 ........
