Knowra Mineral exploration Mineral exploration Mineral exploration is the search for economically valuable concentrations of minerals in Earth’s crust. It combines geological interpretation, field investigation, and testing to assess potential deposits.
Mineral systems : A mineral system is the set of geological processes that generates, transports, and concentrates valuable minerals. Exploration looks for evidence of each process that could have formed a deposit.
Porphyry copper deposit : A porphyry copper deposit is a large, low- to moderate-grade ore body associated with an intrusive igneous system. Its broad alteration zones and metal patterns create exploration targets across large areas.
Prospecting : Prospecting is the search for mineral deposits through field observation, sampling, and preliminary testing. It is the field-based practice from which systematic mineral exploration developed.
Mineral resource classification : Mineral resource classification groups estimates by geological confidence and supporting evidence. Classification communicates uncertainty in exploration results before a deposit is proven economically mineable.
Geological mapping : Geological mapping records the distribution, structure, and relationships of rocks at the Earth's surface. Maps reveal structures and rock units that may control mineralization.
Orogenic gold deposit : An orogenic gold deposit forms in structurally controlled hydrothermal systems associated with mountain-building processes. Faults and shear zones guide exploration for this structurally focused deposit type.
Georgius Agricola : Georgius Agricola was a sixteenth-century German scholar whose writings documented mining and metallurgy. His work helped preserve and organize knowledge of ore finding and mining.
Mineral reserve : A mineral reserve is the economically mineable part of a measured or indicated mineral resource. A successful exploration discovery may progress toward a reserve after technical and economic evaluation.
Geochemical exploration : Geochemical exploration analyzes rocks, soils, water, or vegetation for chemical patterns linked to mineral deposits. Anomalous element concentrations can trace concealed mineralization or its pathways.
Lithium pegmatite : A lithium pegmatite is a coarse-grained igneous rock body that can host lithium-bearing minerals such as spodumene. Field mapping and geochemistry help identify pegmatite bodies and assess their lithium potential.
