isolated mineralized stones, showings, occurrences, altered areas
Identification of possible markers of a mineralized area.
CodeListValue
anomalies
Anomaly or anomalous area which geophysical or geochemical properties are different from areas around and which might indicate the presence of a mineralizing process in the vicinity.
CodeListValue
identification of key minerals
Identification of particular minerals which may indicate a possible mineralized area or accompany a mineralizing process.
CodeListValue
detailed prospect map with location of mineralized areas
A detailed map with location of all the mineralized occurrences whatever their size and representation of their relationships with lithology, structures, alteration zones, anomalous areas, sampling analysis results.structuredAnomalies
CodeListValue
structured anomalies
Narrowing of the area under mineral prospection, and a more detailed internal structure
CodeListValue
prospect boundaries refinement
Progressively reducing the surface area until the discovery of a mineral deposit.
CodeListValue
mineralization primary reconnaissance
The first attempts to see (removal of overburdens, trenching) or to intercept (auger, subsurface percussion drilling), and to sample primary mineralization.
CodeListValue
mineralization indicated
The first attempts to roughly delineate the ore body, using reconnaissance drilling (percussion and then core drilling), to sample it in detail, and to approximately evaluate the resource using geological interpretation, beneficiation tests.
CodeListValue
ore deposit indicated
The presence of an ore body has been demonstrated using systematic core drilling and sometimes some preliminary mining workings. The external geometry of the ore body and its internal structure (including ore grade distribution) starts to be well-known.
CodeListValue
ore deposit indicated and estimated
Refinement of previous knowledge using statistical tools allowing for example interpolations between drill holes, and definition of enriched areas.
CodeListValue
feasibility study report available for mining decision
Technical economic study aimed at assessing the possibility to launching a mine venture. industrialTest
CodeListValue
industrial test
Intermediate phase between laboratory tests and actual plant.
CodeListValue
geophysical anomaly
Area where geophysical properties (e.g. radiometric, magnetic, electromagnetic, gravity) differ from surrounding areas and which may be the result of mineralisation.
CodeListValue
geochemical anomaly
Area where geochemical properties (e.g. single or multiple element concentrations or isotope ratios) differ from surrounding areas and which may be the result of mineralisation.
CodeListValue
negative feasibility study
Completion of an economic evaluation of the mineral project at a level sufficient for a feasbility study with a resulting determination that extraction is not reasonably justified. A Feasibility Study is a comprehensive technical and economic study of the selected development option for a mineral project that includes appropriately detailed assessments of all factors necessary to determine at the time of reporting whether extraction is reasonably justified (economically mineable).
CodeListValue
mineral resource defined
Work has been completed to identify a three dimensional zone of mineralization and estimate its tonnage and grade to the standard of a "mineral resource". Result allows definition of a 'Measured Mineral Resource' as defined by CIM (2010-11-27)
CodeListValue
mineral reserve defined
Definition of a three dimensional body of mineralization in sufficient technical detail and accompanied by an economic evaluation so that the estimated tonnage and grade can be classified as a mineral reserve. A Mineral Reserve is the economically mineable part of a Measured or Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study.
