The soil anomaly on ADU,s ground is nearly twice as wide and over 1.5gms better than RBK,s, which you would expect on lower lying ground directly to the south, denudation and secondary enrichment migration into sink traps, and the re- solidification of all that early magma, and the subsequent erosion to lower levels of the heaviest elements combining, is what we in Oz are used to mining, dead easy open pit sedimentary deposits.
ADU, I believe, have exactly the same scenario unfolding.
ADU, also have, what was probably one of the first colonial era multiple parralel gold reefs and stockworks found in what is now Ghana, plenty of old workings just south of the Salman village, (thats why it,s there) which must, in the past, have supported many local workers. The prospector,s at that time, would have then rushed north, as the gold found would have paid for upland exploration, probably paid for by new syndicates out of London, this is now called the Ashanti shear, rich as.
