Geophysical exploration for gold – A review

Exploration Geophysics, 1986
Abstract It is almost impossible to get a direct geophysical response from gold because of the low grades in deposits, except when electromagnetic detectors are used for individual shallow nuggets. However, indirect geophysical indications may occur through association of gold with particular host rocks, marker beds, or structures ...

The importance of brownfields gold exploration

Mineralium Deposita, 2019
Significant growth in the size of gold Resources on many mines of the Yilgarn Craton has occurred well after the deposit was discovered and after mining had commenced. Examples include the Kalgoorlie and Norseman goldfields found more than a century ago and the Jundee and Sunrise goldfields discovered in the 1990s.

A scale-integrated exploration model for orogenic gold deposits based on a mineral system approach

Geoscience Frontiers, 2020
Concept-based orogenic gold exploration requires a scale-integrated approach using a robust mineral system model. Most genetic hypotheses for orogenic gold deposits that involve near-surface or magmatic-hydrothermal fluids are now negated in terms of a ...

Remote sensing satellite-based structural/alteration mapping for gold exploration in the Ketté goldfield, Eastern Cameroon

Journal of African Earth Sciences, 2021
In-situ mineral prospecting studies in the tropics face challenging environmental conditions leading to paucity of data and structural mapping of new mineralizations.

Lithological and alteration mineral mapping for alluvial gold exploration in the south east of Birao area, Central African Republic using Landsat-8 Operational Land Imager (OLI) data

, 2020
Geological field mapping and mineral exploration still remain very laborious in many parts of the inter tropical regions of African plate due to remoteness, low security and high cost.

Multivariate statistical analysis of trace element compositions of native gold from orogenic gold deposits: Implication for mineral exploration

, 2021
The mineralogy and chemical composition of native gold from twenty-seven representative orogenic gold deposits were investigated using optical microscopy, electron probe microanalysis (EPMA), and laser ablation-inductively coupled plasma-mass ...
