The induced polarization method makes use of the capacitive action of the subsurface to locate zones where clay and other chargeable minerals are located within the host rock. With IP, you can tell very distinctly what is in the ground if it holds a charge because you end up with two maps—i.e., resistivity and IP—at the same time.

Mineral exploration aims to discover deposits of minerals and rocks that can be used to meet the resource needs of society. It encompasses the search for industrial raw materials (e.g., clay, limestone, sulphur, salts, and fertilizer minerals and rocks), ores from which metals are extracted (e.g., iron, copper, and zinc ores), and ...

Borehole thermal methods have been applied in geothermal exploration, but have seldom been used in mineral exploration. However, this method has potential usefulness in exploration and in geoenvironmental investigations (Ovnatanov and Tamrazyan, 1970; Brown and others, 1980; Zielinski and others, 1983; Houseman and others, 1989).

Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their ...

M.E. Best, in Treatise on Geophysics (Second Edition), 2015. Abstract. Geophysical methods have been applied to mineral exploration and development for more than 100 years. Mineral exploration relies on the entire suite of modern geophysical techniques to narrow down the search for metallic and nonmetallic mineral deposits.

Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties. It is most often used to detect or infer the presence and position of economically ...

This method also does not provide any information on mineral chemistry and phase identification can be somewhat ambiguous. Routine exploration of mineral sands typically produces many thousands of samples. Geologists therefore require both rapid and low cost techniques that can be used cost effectively on a more routine basis.

Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.

Mining Methods. There are four key stages of work involved in mining for minerals. These include: 3415, 3416 Prospecting – The purpose of this stage is to identify areas that are likely to contain mineral deposits. The work includes geological, geochemical and geophysical surveys (e.g. seismic surveying), aerial surveys, including the taking of samples by low-impact mechanical methods.
