Moose River gold mine

Moose River (Touquoy) Open Pit Gold Mine is located approximately 60km north east of Halifax, Nova Scotia.

After a feasibility study was completed in 2015, mining of the current open pit at Touquoy commenced in 2017, with commercial production declared in March 2018. The operation was delivered on time and on budget and exceeded production guidance in the first year.

Commissioned in October 2017, the processing plant at Touquoy is a conventional CIL circuit with a nominal capacity of 2.0 million tonnes per year.

Further to the currently operational open pit, there is planned expansion of three additional pits nearby at Beaver Dam, Fifteen Mile Stream and Cochrane Hill, with a combined estimated mine life for the operation of 12 years.

As at 25 March 2019, the Atlantic Gold operation had a combined estimated 1.9 million ounces of gold in reserves at a grade of 1.12 grams per tonne. 

St Barbara acquired Atlantic Gold and its Moose River operations on 19 July 2019.


100% – St Barbara

Deposit Type:

Shales; Veins

The Touquoy and Beaver Dam mines are situated along the same geological trend as Atlantic Gold’s two other deposits, Fifteen Mile Stream and Cochrane Hill. The deposits are hosted within the same stratigraphy of the Meguma Terrane, which is primarily a sequence of Cambro-Ordovician sandstones and mudstones.

At Touquoy, mineralisation is disposed around the anticlinal hinge, whereas that at Beaver Dam is primarily disposed in a tabular zone within the southern limb of the anticline. Gold is distributed throughout quartz-veined grey argillites (shales) at both the locations.

Mining Method‎: ‎

Truck & Shovel / Loader

Conventional open-pit mining method integrating drill, blast, load and haul activities using a leased production fleet primarily including diesel-powered down the hole (DTH) drills, diesel-powered reverse circulation (RC) drills, 4.5m³ bucket-sized diesel hydraulic excavators, 7m³ bucket-sized wheel loaders, and 64t payload rigid frame haul trucks for production loading.

Processing Method:

Gravity separation; Agitated tank leaching; Concentrate leaching; Electrowinning.

Conventional gold mill operation integrating a three-stage crushing and ball milling to a grind of 80% passing 150 microns, with cyclones used in closed-circuit grinding.

The processing plant integrates a centrifugal concentrator, cyanidation facilities, carbon-in-leach (CIL) circuit, pressure zadra circuit, electro-winning circuit and a smelting facility.
