Coresampling determines the depth of the resource, its quality, and the depth of any “overburden”—plants and soils that lie on top of the aggregate resource. The overburden must be removed before the aggregate can be extracted. Because aggregates have a low value per tonne, the amount of overburden has a large effect on whether extraction will be economically viable.
