In addition, and whilst not a definitive metallurgical study, Dr Halley's work indicated that gold is depleted in the upper oxide area and enriched in the lower oxide to fresh rock transition, and the strongest mineralised zones are also depleted in calcium in phengitic altered zones (phengite is a greenish potassium magnesium mica mineral).
