Models and Exploration Methods for Major Gold Deposit Types

For gold exploration, important geophysical advances include airborne gravity, routine 3D inversions of potential field data, and 3D modeling of electrical data. Improved satellite-, airborne - and field-based infrared spectroscopy has significantly improved alteration mapping around gold systems, extending the dimensions of the footprints and enhancing vectoring capabilities. Conventional ...

Exploration information systems – A proposal for the ...

01/08/2019  Consequently, the scale dependency of exploration targeting criteria is a critical issue which must be taken into account in the application of mineral system concepts (Wyborn et al., 1994) in order to generate reliable exploration targets (e.g., Hronsky and Groves, 2008, Ford and McCuaig, 2010, McCuaig et al., 2010, Hagemann et al., 2016a, Joly et al., 2012). Ignoring this and inappropriately ...

A scale-integrated exploration model for orogenic gold ...

01/05/2020  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 global mineral system model. Plausible models involve metamorphic fluids, but the fluid source has been equivocal. Crustal

Basic Gold Prospecting Exploration Methods

Surface seismic techniques used in gold exploration are restricted to seismic refraction and seismic reflection methods. Probably, the first one is the most employed. The equipment employed for both techniques is very similar and assure the travel time of acoustic waves propagating through the subsurface. In the seismic refraction method, the travel time of waves refracted along an acoustic ...

However, the relatively high cost of mobilisation for airborne EM surveys and the limited depth penetration (about 50-75 m for helicopter fixed-boom systems) militates against more common use of this method.A number of different ground electrical and EM methods are being applied to epithermal gold exploration, including resistivity, induced polarisation (IP), controlled source ...

Exploration Targeting - Decennial Mineral Exploration ...

Exploration for orogenic gold deposits in the Abitibi is an example of empirical targeting. These deposits are located along regional scale “breaks”with associated seimentary and d volcanic rocks and common carbonate alteration (Figure 2). Exploration tends to focus on acquiring a land position along these breaks and focusing drilling favourable lithologies and on alteration; typically as ...
