Smith

Mining Method

Conventional sublevel stoping
Blind bench stoping
Ramp bench stoping
Blind Uphole Stoping

The Smith Mine, accessed via a portal from the Dash open pit, was started in 1999 as the pit was being mined out. The Smith Mine complex consists of several mineralized areas that are accessed from the Smith portal, as well as East Dash to the east that will be accessed from a separate portal in the Dash pit.

Gold mineralization in the main Smith, Mahala and West Dash deposits is associated with the northeast trending Coulee Fault and west-northwest trending faults and dikes. In Zone 1, high-grade gold mineralization is hosted in the upper and middle portions of the Hansen Creek III unit within a northwest trending horst block between the South Graben fault and the 170 fault. Mineralization in Zones 2 and 3 is directly associated with west-northwest trending dikes. High-grade mineralization occurs within the Hansen Creek II and III units along the steeply dipping dikes.

Gold mineralization in the Mahala area is spatially associated with the west-northwest trending Mahala fault and associated dikes and favorable ore-host stratigraphy, including the Hansen Creek Formation and lower beds of the Roberts Mountains Formation. Mineralization at East Mahala occurs primarily in broad, Southeast-dipping lenses in the hanging wall of the Coulee Fault.

The West and East Dash deposits occur at the ends of the west-northwest trending Dash Fault system which formed the mineralization mined in the Dash pit. The West Dash deposit occurs at the intersection of the Coulee fault and the west-northwest trending Dash fault. West Dash is accessed through the Smith Portal. The East Dash deposit lies to the east of the Dash pit and will be accessed by a separate portal in the pit. At East Dash, most gold occurs in two lenses parallel to the Dash Fault and dipping to the northeast.
