-- Description --
Recaps the work which has been done from regional reconnaissance, surface detailed prospecting, subsurface prospecting, assessment of the resource, to evaluation of the ore deposit. Depending on the work done on occurrences and prospects, allows an estimate of the 'still to be discovered' potential of an area. A detailed assessment with no result would lead to a pessimistic opinion.
-- Definition --
The commodities present in the resource ranked by importance order.
-- Description --
Determining the rank of a commodity is not as simple as it may look: not only the tonnage (expressed in tons of metal) has to be taken into account, but also the scarcity and thus the price of the commodity. A deposit containing 500,000 t Cu and only 50 t Au will be classified as an Au-(Cu) deposit.
-- Definition --
One or more periods of mining activity of the earth resource.
-- Description --
Indicates if this resource is the subject of exploitation, and if so of which type. Depending on several factors (type of mineralization, size, grade, shape, depth, etc.) one or several (combined) methods may be used, including off site methods, surface mining (among which methods related to the exploitation of alluvial/elluvial deposits), underground mining. Knowledge about these methods is important as it may be strongly related to the quantity and type of wastes and environmental impacts generated by the extraction.

-- Definition --
The importance of the deposit for the commodity.
-- Description --
Several commodities may be of interest inside a deposit. A deposit may be a very large deposit for one commodity (this commodity is the main one) and only a medium-sized deposit for some other commodities. Such a ranking is based on a statistical study of a large set of deposits throughout the world to ensure that it is valid. It is made using histograms allowing for each commodity to define class boundaries and what is a super large, a large, a medium-sized etc deposit for this commodity. This classification is based on the potential or endowment: reserves + resources.
implementingRule
-- Definition --
The rank of the commodity.
-- Description --
Commodity rank is based on endowment, i.e. (cumulated) past production + reserves (not including past production) + resources, or if the deposit has never been exploited, reserves + resources. A statistical comparison with a large set of deposits throughout the world enables the determination of the deposit as class A (very large), B (large), or C (medium-sized) for a particular commodity, and also which commodity is the main one, the 2nd one, etc. The rank of a commodity is thus not based on political or economic considerations.
