This study revealed that the occurrence of gold within the mining pits is structurally controlled and disseminated. The study has provided the effectiveness of geophysical application in mineral exploration and the methodology can be applied in any similar geological terrain to unravel mineralization potential.
Much effort has been made by researchers to discuss applications of geophysics in mining but geophysical techniques are still been used below optimal capacity. ... Magnetic technique is the most commonly used geophysical tool in gold exploration, as it is in exploration for other metals (Doyle, 1990). Successful use of magnetic technique for ...
Abstract Borehole logging tools based on pulsed neutron technology are used to infer geophysical parameters such as bulk density. If fitted with a gamma-ray spectrometer, they may also measure elemental mass fractions of a variety of formation elements. Spectrometric borehole logging tools of this kind are established in the oil and gas industry. With the demand …

The effective application of these technologies can enable a better understanding of the unseen orebody and the surrounding rock mass ahead of the mining face; the potential benefits of applying in-mine geophysics is demonstrated through a selection of case studies conducted in deep-level hard rock mines in South Africa.
The Borehole Geophysics Section of the Geological Survey of Canada has acquiredmultiparameter borehole geophysical logs in several holes in gold deposits in Ontario. Thesemeasurements were made to document the geophysical signatures of the ore zones and host rocks,and to determine which physical properties may be used to outline …
Practically all the gold and uranium produced by the Republic of South Africa is won from the auriferous conglomerates of the Witwatersrand System, and exploration is oriented towards locating areas underlain by these conglomerates (reefs). The Witwatersrand Basin is filled by sedimentary and volcanic rocks up to a total thickness of 40 to 50 thousand feet. The …
Geophysics is a branch of Earth science that utilizes principles and techniques from physics to study the physical properties and processes of the Earth. It involves the application of various methods to investigate the subsurface structure, composition, and dynamics. Geophysical methods are essential tools for understanding the Earth's interior and …

The effective application of these technologies can enable a better understanding of the unseen orebody and the surrounding …
Most geophysical surveys are carried out for exploration and to locate resources. It is worth noting that Article 2 in this Special Issue presents a novel application of geophysical inversions in mine development. The geotechnical parameters (e.g., cohesion, plastic index, moisture content, friction angle) are vital for the planning and ...
Location Intelligence is fundamental across the mining life cycle, from mineral exploration to mine remediation. With minerals and metals being depleted faster than we can replenish, understanding spatial context and integration with other geoscience technologies is critical in the strategic and environmentally sustainable development of new reserves.
