Exploration & Mining Glossary
Mining and Exploration glossary for words relevant to Peel Mining projects
Electromagnetics (EM) (Geophysics) - A geophysical survey method which measures the electromagnetic properties of rocks. The response vary according to the conductivity of the ground. EM surveys can be used to help detect mineral deposits, especially base metal sulphides via detection of conductivity anomalies which can be generated around sulphide bodies in the subsurface. EM surveys can be carried out in the air, on the ground or within a drillhole.
Exploration (mineral) - The sequence of searching for economic mineral/mineral assemblages in an area. It ranges from early stage exploration, the reconnaissance for a new mineral prospect to late stage exploration which involves infrastructure and mine development.
Extension (geological) - Structural features formed by the stretching of the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle). Peel Mining context: The Cobar Basin was opened by transtensional NE-SW extension.
