It is a bedded deposit enriched by supergene water, and has an estimated tonnage of 6,000 tons per vertical foot. The ore is in a number of beds interspersed with an approximate equal footage of decomposed schist. Two shafts indicate ore down to 40 feet, and it is thought that it may continue well below that level. {"type": "Polygon", "coordinates": [[[120.0, -33.7], [120.3, -33.7], [120.3, -33.5], [120.0, -33.5], [120.0, -33.7]]]} 120.0 120.3 -33.7 -33.5 AU-WA Earth Sciences GA Publication Published_External Record economic geology mineral deposits resource assessment Download the Record (pdf) documentDigital Download the Record (pdf) PDF Unnamed resource documentDigital HTML
