A Mineral Reserve is the economically mineable part of a Measured or Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This Study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can ...
The Geological Survey of Arkansas was first established in 1857, at the direction of Governor Elias Nelson Conway. David Dale Owen was the agencies first geologist. Initially, the agency received funding for only three years, which limited the agencies findings and publications, and the agency was left without funding during the Civil War.
Quantitative mineral-resource assessments are defined as the numerical estimate of the amount, quality, and in some cases, value of undiscovered minerals (that is, metal or industrial mineral) present within a specified area (tract). Their purpose is to provide a framework for making decisions by governments or institutions concerning mineral ...
A Probable Mineral Reserve has a lower level of confidence than a Proved Mineral Reserve but is of sufficient quality to serve as the basis for decision on the development of deposit. A Proved Mineral Reserve is the economically mineable part of a Measured Mineral Resource. It includes diluting materials and allowances for losses which occur ...
The 1922 discovery of the Smackover oil field, after which the Smackover Formation is named, resulted in a sizeable oil boom in southern Arkansas. [ citation needed ] In addition to being a petroleum reservoir, as of 2015, the brine from the Smackover Formation is the only source of commercial bromine in the United States.
SGS Genesis (previously SectCAD, BlkCAD, PolyCAD, Geostat) is the fruit of more than 30 years of expertise in software development for the modelling of mineral resources. . Indeed, in 1981, SGS S.A., formerly Gamma Geostat International Inc. was among the pioneers in computer based geostatistical methods and had created one of the first geological modeling software for the first generation of ...

Diagram as published by McKelvey in 1973 [1] Diagram as published by McKelvey in 1976 [2]. A McKelvey diagram or McKelvey box is a visual representation used to describe a natural resource such as a mineral or fossil fuel, based on the geologic certainty of its presence and its economic potential for recovery.
