"Cowell was officially gazetted in 1880 by Governor Sir William Francis Drummond Jervois who named the town after Major-General Sir John Clayton Cowell who was, at the time, the Master of the Queen's Household for Queen Victoria........The history of jade in the Cowell dates from 1965 when a local farmer, Harry Schiller, discovered significant deposits of nephrite jade near Cowell. It wasn't until 1974, when the South Australian government became involved, that the potential of the area was realised. A geological assessment found more than 100 separate jade outcrops in a 9 sq km area which is now known as the Cowell Jade Province. The deposit is recognised as containing about 80 000 tonnes which means that it represents about 90 per cent of the world's known jade reserves. The Cowell jade deposit is recognised as one of the oldest and largest in the world." (Aussie Towns). 63 pages including index. Please check with us for an accurate postage cost.
