This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western mining operations. All costs listed are in 2012 US.

Openpit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. It is a form of surface mining. The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining.

Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping.

equipment, which may include a mining loader, shovel or excavator. Loaders lift the ore or waste material onto the trucks for removal from the mine. In an openpit mine, loader types can include electric rope, hydraulic excavators including backhoe excavators, and frontend loaders (also called wheel loaders) (Er˘celebi and K rmanl, 2000).

Strip mining is sensible when the ore body is near the surface. The practice includes some of the largest machines on earth, removing long strips of overlying soil and rock and then removing coal deposits. Openpit mining utilizes blasting and mineral removing, digger deeper into the earth causing a craterlike result.
