The concentration of an element of interest in a potentially mineable ore deposit.

A measurement of the metal content in ore.... more on: Ore grade

measured in weight percent bitumen, is a measure of the richness of the ore. In most cases, the ore grade is based on the ore quality that is fed to the extraction process.

The percentage of bitumen by weight in the oil sands.

Ore grade is a measure that describes the concentration of a valuable natural material (such as metals or minerals) in its surrounding ore. Ore grade is used to assess the economic feasibility of a mining operation: the cost of extracting a natural material from its ore is directly related to its concentration, and the cost of extraction must be less than the market value of the material being mined for the operation to be economically feasible.
