rocks as replacement deposits; an important source of lead and silver.
Study of variation of chemical elements in rocks or soil.
Study of the Earth’s history and life, mainly as recorded in rocks.
Study of the earth by quantitative physical methods, either by
surveys conducted on the ground, in the air (by fixed wing aircraft or helicopter) or in a borehole
A heavy, soft, ductile, malleable precious metal used in jewelry, dentistry, electronics and
as an investment.
The amount of valuable metal in each tonne or ore, expressed as grams per tonne for
precious metals. Cut-off grade – is the minimum metal grade at which a tonne of rock can be

metallurgical process and treatment or ore, based on actual experience or laboratory testing.
A unit of measurement commonly used to quantify the
concentration of precious metals.
Equipment used within a plant to recover gold from the ore using the
difference in specific gravity between the
gold and the host rock. Typically used are shaking tables, spirals, etc.

A classification of rocks formed from the solidification from a molten state.
Said of an igneous rock that invades older rocks.
A method of extracting gold from ore by a chemical solution usually containing cyanide.
Vein of metal ore.
An igneous rock composed chiefly of dark iron and manganese silicate minerals.
A geophysical survey conducted on the earth’s surface that measures
variations in the earth's magnetic field caused by variations in rock type or geological structures.

The science and technology of extraction of metals from their ores and the
refining of metals.
A process whereby the composition of rock is adjusted by heat
and pressure/A class of rock affected by metamorphism.
A plant where ore is ground fine and undergoes physical or chemical treatment to extract
the valuable metals.
The concentration of metals and their chemical compounds within a body of
