Exploration & Mining Glossary

Mining and Exploration glossary for words relevant to Peel Mining projects

Geophysical model - A 3D representation of the project area based on geophysical interpretations. This method is chiefly utalised in the early exploration phase, and in collaboration with mapping and geochemcial modelling helps to define an area of interest for further exploration.
Geophysics - The study of the physical properties of rocks and minerals. Data gathered for this may be attained from various geophysical surveying methods, such as; an Induced Polarization (IP), Downhole Electromagnetic (DHEM) or Gravity survey.
Geotechnical drilling - Is drilling specifically performed to investigate nature and stabilty of the rocks in the area of a planned open pit or underground mine. This is achieved by investigating the structural, lithological, hydrogeoloical and alteration issues within the rocks.
Gold (Au) - Is a rare previous metal. It is typically found in rocks and veins as very fine grains (not typically visable with the naked eye). It typically occurs and natually alloyed with copper, and when present, is found within the chalcopyrite in chalcopyrite-quartz veins.
Gold (Au) equivalent - The monetary value of all the metal divided by the current market value of Gold to provide an equivalent quantity of Gold in grams per tonne.
Gossan - An intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.
Gravity (Geophysics) - Is a geophysical method which is based on Newton's Law of Gravitiation (F=G{{m_1m_2}{r^2}}), which stipulates that two mass points will exert an attractive force on each other. This idea implies that an orebody, which embodies a greater mass than it’s surrounding host rock, should therefore produce a larger attractive force than the background, ergo producing a distinctive signature.
Greenfields exploration - Uncharted territory, where mineral deposits are not already known to exist.
Hanging wall - Refers to the mass of rock strata overlying the orebody (see Ore). For the opposing side, see Footwall.
High grade - Rich ore. As a verb, it refers to selective mining of the best ore in a deposit.
