  2. Mineral resource classification - Wikipedia

    en.wikipedia.org/wiki/Mineral_resource...

    Mineral Reserves are subdivided in order of increasing confidence into Probable Mineral Reserves or Proved Mineral Reserves. 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 ...

  3. National Instrument 43-101 - Wikipedia

    en.wikipedia.org/wiki/National_Instrument_43-101

    The National Instrument 43-101 requires substantially more technical disclosure to the market than the equivalent JORC Code, because the JORC Code is primarily a code for reporting the status of a mineral resource, whereas NI 43-101 is a code of securities disclosure. This distinction is based on the derivation of the two codes: the JORC Code ...

  4. Mineral resource estimation - Wikipedia

    en.wikipedia.org/wiki/Mineral_resource_estimation

    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.

  5. McKelvey diagram - Wikipedia

    en.wikipedia.org/wiki/McKelvey_diagram

    The terminology used may vary somewhat, [6] [7] but resources in a McKelvey diagram fall into three main areas: [8] Reserves, which are already discovered and commercially-viable mineral deposits, [8] [1] Contingent [8] or conditional [1] resources, whose existence is known but which are not commercially viable at present,

  6. PERC Reporting Standard - Wikipedia

    en.wikipedia.org/wiki/PERC_Reporting_Standard

    PERC is a constituent member of the Committee for Mineral Reserves International Reporting Standards - CRIRSCO [6] and is the European equivalent of JORC [5] in Australasia, CIM [9] in Canada, SAMREC [10] in South Africa and similar reserves standards bodies elsewhere.

  7. United Nations Framework Classification for Resources

    en.wikipedia.org/wiki/United_Nations_Framework...

    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]

  8. Proven reserves - Wikipedia

    en.wikipedia.org/wiki/Proven_reserves

    Proven reserves (also called measured reserves, 1P, and reserves) is a measure of fossil fuel energy reserves, such as oil and gas reserves and coal reserves. It is defined as the "quantity of energy sources estimated with reasonable certainty, from the analysis of geologic and engineering data, to be recoverable from well established or known ...

  9. Unconventional (oil and gas) reservoir - Wikipedia

    en.wikipedia.org/wiki/Unconventional_(oil_and...

    Schematic unconventional reservoir classification expressed as fluid energy vs flow potential based on initials without stimulation. Unconventional (oil and gas) reservoirs, or unconventional resources (resource plays) are accumulations where oil and gas phases are tightly bound to the rock fabric by strong capillary forces, requiring specialized measures for evaluation and extraction.
