Deposit Type

  • Vein / narrow vein
  • Mesothermal

Summary:

The known deposits within the Project area are considered to be examples of turbiditehosted mesothermal gold deposits.

The Meguma Terrane of Nova Scotia hosts the Moose River Member, Tangier Member, and Taylors Head Member of the basal greywacke-dominated Goldenville Formation. Gold mineralization is generally hosted in argillite and/or greywacke sequences of the Moose River Member and is associated with regional-scale anticlines. Structural repetition due to folding and faulting may result in thickening of gold-bearing units.

Gold occurs as native gold, and has been observed in a number of settings, including along shear cleavage, hair line fractures; in pressure shadows; as inclusions; on the margins of sulphide grains; in thin, bedding-parallel quartz veins and stringers. Mineralization is associated with sulphides, including arsenopyrite, pyrite and pyrrhotite. Lesser chalcopyrite, galena, and sphalerite have been observed.

Gold grade was estimated using multiple indicator kriging (MIK) for all deposits. The basic unit of estimation is a panel with horizontal dimensions equal to the average drill hole spacing.

Dimensions
Touquoy: strike extent = 810m ; width = 50m; vertical extent = 150m.

Beaver Dam: strike extent = 810m ; width = 50m; vertical extent = 200m.

Fifteen Mile Stream: strike extent = 1400m ; width = variable 20m to 100m; vertical extent = 225m.

Cochrane Hill: strike extent = 950 ........

Mining Methods

  • Truck & Shovel / Loader

Summary:

Mining is based on conventional open pit methods suited for the project location and local site requirements. The mining fleet will include diesel powered down the hole (DTH) drills with 144 mm bit size for production drilling, diesel-powered RC drills for bench-scale grade control drilling, 5 m3 bucket size diesel hydraulic excavators and 7 m3 bucket sized wheel loaders for production loading, and 64 t payload rigid-frame haul trucks and 41 t articulated trucks for production hauling, plus ancillary and service equipment to support the mining operations. In-pit dewatering systems will be established for each pit. All surface water and precipitation in the pits will be handled by submersible pumps.

Mine operations will continue at Touquoy and will move to Beaver Dam once the Touquoy open pit is exhausted in 2023. At Touquoy, ore is hauled to a crusher 700 m north of the pit, which feeds the process plant; and waste rock is deposited into a waste rock storage facility (WRSF) 1,000 m east of the pit, or is used as rock fill in construction of the TMF that is located 800 m east of the pit.

At Beaver Dam, ore will be hauled to a crusher that will be located 600 m south of the pit, and then crushed ore will be hauled by on-highway haulers from Beaver Dam to the process plant at Touquoy operations; and waste rock will be deposited into WRSFs to be situated 650 m south and 1,650 m west of the pit. Mine planning and mining cost estimates are limited to the ........
