Overburden - Wikipedia

In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an ex

Stripping ratio - Wikipedia

In surface mining, stripping ratio or strip ratio refers to the amount of waste (or overburden) that must be removed to release a given ore quantity. It is a number or ratio that express how much waste is mined per unit of ore. The units of a stripping ratio can vary between mine types. For example, in coal mining the stripping ratio is commonly referred to as volume/weight.

As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).
