As State Geologist of Alabama, Walter B . Jones directed research on many topics including economic minerals, surface and groundwater, petroleum, geologic mapping, fossils, caves, and archaeology.

Also, the formation of this type of chemical assemblage is commonly located near phosphate and rare-element deposits, giving it another important characteristic as a good indicator to where more economic minerals can be found.

For an artisanal miner to increase their use of better technologies there a few influencing factors that they take into place : ( 1 ) increased or comparable simplicity, ( 2 ) quick recovery of the economic mineral, and ( 3 ) demonstrated financial gain.
14.
Exploration continues within the West Coast region for further economic mineral deposits, and due to the complexity of the geology, there is always the possibility that new mines will open : the Henty Gold Mine is a good example as it commenced operation in the 1990s.
15.
"Indicated resources " are simply economic mineral occurrences that have been sampled ( from locations such as outcrops, trenches, pits and drillholes ) to a point where an estimate has been made, at a reasonable level of confidence, of their contained metal, grade, tonnage, shape, densities, physical characteristics.
