Gold exploration in tropical landscapes - Ingeoexpert EN

Aug 04, 2021  Gold exploration in tropical latitudes goes hand in hand with small-scale and artisanal gold mining. With careful study, the style and the geographical locations of surface mine workings can be used as vectors to find the primary gold at depth.

gold exploration in the tropics - mon-plaisir-gourmand

In the tropics the laterite cover around outcropping gold-quartz-veins often shows a pronounced gold dispersion halo which can be traced by geochemical exploration. It is proved that the primary gold is partially moved in solution and re-precipitated in secondary gold particles with lower grain size and reduced Ag content.

This study shows that ferruginous pisoliths and clasts in the cover are potential sampling media for Au exploration in the Yamarna Terrane. The exploration methods used in this study can be also applied in similar covered terrains not only in Australia but also in areas with complex weathering histories in the tropics and sub-tropics.

to mineral exploration. The problems encountered in tropical exploration are well known. The tropics are wet, and highly vegetated with little outcrop in areas of low relief; saprolitic weathering is often extensive and deep but variable, depending on the bedrock to some extent, but more preferentially affected by the presence of sulphides.

Regolith geochemistry for mineral exploration – CSIROpedia

Sep 17, 2018  Resurgence in gold exploration during the mid-1980s focused in WA on small but rich, easily mined deposits in the regolith. Gold is concentrated both at depth and in the near-surface lateritic horizons, but paradoxically was absent from intervening horizons, implying that gold is dissolved and reprecipated during weathering.
