Conversion resources to ore reserves requires determining of economically viable cut-off grade. This is an economic threshold which is used for delineating (constraining) of the ore bodies. Estimation of the economic cut-off is a complex economic problem (Lane 2015) which is beyond the scope of a mine geologist responsibilities and …
6See Appendix C for resource and reserve definitions and information concerning data sources. 7For Australia, Joint Ore Reserves Committee-compliant or equivalent reserves were 24 billion tons of crude ore and 11 billion tons of contained iron. 8For Ukraine, reserves consist of the A and B categories of the Soviet reserves classification system.

Ore Reserve means the economically mineable part of a Measured and/or Indicated Mineral Resource.It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at pre‐feasibility or feasibility level as appropriate that include application of Modifying Factors.Such studies …
extract the ore reserve estimated for that part of an orebody from the total mineral resource estimates. This subset from the total mineral resource estimates is termed Ore Reserve Depleted by Mining [4]. Having obtained this subset, the resource engineer is able to conduct direct comparison with grade control, mine output and processing results.
According to ITA calculations, the world's reported tin resources at the end of 2019 totalled some 15.4 Mt, including some 5.5 Mt of reserves. Of this, some 39% (6.0 Mt) of resources and 29% (1.6 Mt) of reserves were compliant with CRIRSCO standards. The top five countries as a proportion of global compliant resources were Russia (29% ...

The term "ore" applies to reserves of some kinds of mineral commodities, generally metallic, but for want of another term it is some- times applied to nonmetallic commodities. Definitions given here for "measured," "indicated," and "inferred" resources may be applied to both iden- tified economic resources (reserves) and identified
Ore is a deposit in Earth's crust of one or more valuable minerals.The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and …
A mineral reserve is "the economically mineable part of a measured and/or indicated mineral resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibility or Feasibility level as appropriate that include application of Modifying Factors.
1. Australia – 48 billion tonnes. Australia is home to the largest reserves of iron ore worldwide, with an estimated 48 billion tonnes identified as of 2019. The majority of the country's iron ore resources are located in the state of Western Australia, particularly the Pilbara region, with much of the remainder based in South Australia.

A Mineral Reserve includes diluting materials and allowances for losses that may occur when the material is mined. Probable Mineral Reserve. A probable mineral reserve is the economically mineable part of an Indicated and, in some circumstances, a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study.
Productive Ore Reserve. It is a generic term for the three grades of reserves, i.e., developed ore reserves, prepared ore reserves, and blocked-out ore reserves, into which the ore resources planned to be mined are classified according to the degree of preparation of mining engineering in the mine production process.
