Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as openpit, opencut or opencast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta''s bitumen reserves are close enough to the surface to be mined.
