METHOD OF MINING. Mining will be of unconsolidated sands (silica sands) at surface. Extracted sand from the face will be shifted by a conventional front-end loader to a mobile feed unit. The unit contains a washed 3mm screen that will remove oversize and organic material. This material is anticipated in low volumes and will be side-cast by the ...
