The Panglo Gold Deposit (located just north of Kalgoorlie) was the second Au-in-carbonate case history, following on from the Bounty Gold Deposit, and was highly significant in its own right (Lintern and Scott, 1990). Firstly, it suggested the Au–carbonate correlation was widespread and not restricted to Bounty alone some 250 km south west.
In a first generation kaolinite replaces the silicate minerals of the parent rock which already occurs in the saprolite stage. In a second generation very fine-grained and iron-stained kaolinite with lower crystallinity fills small voids and fissures in the lateritic matrix.The two …
Mass balance calculations, assuming immobility of Ti and/or Zr, and constrained by specific gravities, indicate removal of large amounts of material during weathering, resulting in volume losses up to 30% in saprolite, and as much as 60% in soils.;Gold has been leached from soils at both sites, and from weathered zones at Ridgeway, to be ...
saprolite and become larger in the nodular horizon. Moreover, in the lateritic profiles of Surinam and Liberia, Au is essentially located at the interface of B and C ho- rizons and primary gold dispersion is clearly evident up to the surface . In the laterite of the Boddington gold deposit (Western Australia), the highest Au values occur
Gold is also present in the saprolite overlying bedrock, in the oxidized equivalent of the sulphide alteration assemblage. Prospective saprolite hosts an assemblage of sericite-chlorite-silica, with disseminated limonite and "box-works" of limonite with rare occurrences of chalcopyrite. ...

DESCRIPTIVE MODEL OF LATERITE-SAPROLITE Au By Gregory E. McKelvey BRIEF DESCRIPTION SYNONYM: Eluvial gold placers (Boyle, 1979), Au-bearing saprolite (Becker, 1895). DESCRIPTION: Au disseminated in laterite and saprolite that developed under conditions of tropical weathering (fig. 32) over a wide variety of bedrock types but distal to known bedrock gold deposits.
The placer gold is found in the creeks and rivers of the state with most of the gold being found close to bedrock. Another place where it is possible to find placer gold is in a particular type of deposits called a saprolite that is formed by the deep weathering of crystalline rocks turning them into a mixture of clay and quartz grains.

Economic gold mineralization has been recognized in sedimentary and volcanic rocks, while the intrusions show only rare gold occurrences and the dykes are totally devoid of any mineralization. The pits at Rosebel are primarily excavated in either the sedimentary or volcanic rocks. Consequently, the saprolite …

The saprolite ores, which cover a considerable area in the Piedmont region of the southern * United States, contain large amounts of gold but this type of ore has hitherto not proven amenable to any of the ordinary methods of concentration used on precious metal ores.
Gold remains untouched in the saprolite and only higher up in the duricrust and soil dpes it becomes part mobile as seen in the form of rounding, pitting and dendritic forms. Therefore, organic and cyanide complexes formed in th soil and duricrust are likely to operate due to the high biomass present in these climates. The likely case is ...

The saprolite graduallybecomes harder as it merges into saprock and primary lithology becomes identifiable.The residual clay is depleted in Au compared to underlying saprolite, saprock and rock. At Bountyand Bounty East the mean Au concentrations in the residual clay are approximately 25% of the meanAu content for bedrock.
