A Probable Mineral Reserve is the economically mineable part of an Indicated Mineral Resource, and in some circumstances, a Measured Mineral Resources. It includes diluting material and allowances for losses which may occur when the material is mined. A Probable Mineral Reserve has a lower level of confidence than a Proved Mineral Reserve but ...
A Mineral Reserve includes diluting materials and allowances for losses that may occur when the material is mined. [3] 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.
An ore deposit is an economically significant accumulation of minerals within a host rock. [9] This is distinct from a mineral resource in that it is a mineral deposit occurring in high enough concentration to be economically viable. [4] An ore deposit is one occurrence of a particular ore type. [10]
Classification and management of natural resources such as minerals and petroleum are classified using differing schemes. [4] [5] In 1997, UNECE published the United Nations Framework Classification for Reserves and Resources of Solid Fuels and Mineral Commodities (UNFC-1997) as a unifying international system for classifying solid minerals and fuels. [6]
The study is primarily focused on metallic mineral deposits and mineral resources. The techniques employed by other Earth science disciplines (such as geochemistry , mineralogy , geophysics , petrology , paleontology and structural geology ) might all be used to understand, describe and exploit an ore deposit.
The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. [1] Mining in a wider sense includes extraction of any non-renewable resource such as petroleum , natural gas , or even water .
When it’s worth it to refinance your mortgage. Refinancing your mortgage can result in huge financial savings. Think about refinancing your mortgage if:
Vogely has stated that the development of a mineral resource occurs in five stages: (1) The current operating margin (rate of production) governed by the proportion of the reserve (resource) already depleted. (2) The intensive development margin governed by the trade-off between the rising necessary investment and quicker realization of revenue.
