Claim is a mining interest giving the holder the right to prospect and explore for minerals with a defined area.
Deposit is an accumulation of mineral ores.
Exploration Stage is the process of finding ore (commercially viable concentrations of minerals) .
Feasiblity Study is an engineering study to define the technical, economic and legal viability of a mining project.
Grade is the metal content of ore, usually expressed in troy ounces per ton (2,000) pounds.
Mineralization is the concentration of metal in the body of rock.
Ore is material that contains minerals.
Precious Metals are scare and valuable metals such as gold, silver, and platinum.
Probable Reserves are reserves for which there is a lower degree of assurance because sampling and measurement are farther apart.
Proven Reserves are reserves for which quantity is computed from dimension of trenches or drill holes. Sampling and measurement are spaced close enough that the mineral content is well-established.
Production Stage is a project that is actively engaged in that process of extraction.
Reclamation is the restoration of land and environmental values to a surface mine site after the coal is extracted.
Recovery is the proportion or percentage of minerals mined from the original seam or deposit.
Reserves is the part of a mineral deposit that could be economically and legally extracted .
Sampling is the gathering of specimens of ore or wall rock for appraisal. Representative sampling is crucial.
Vein is a crack in the rock filled by minerals that have traveled upward from a deep source.
