In 1918, G. Olsen and his neighbour, Patrick J. Madden discovered silver-lead traces on Mr Olsen’s land at Finney’s Hill, Indooroopilly, a suburb of Brisbane, Queensland, 10km from the city centre. After some promising excavations all over the property approximately 200 feet above sea level, a mineral lease was granted to them and the first ore recovered from the site was dispatched to Cockle Creek, N.S.W. for smelting.
