Lead

Lead was the first metal mined in Australia at Glen Osmond in South Australia in 1841, after the wheel of a cart being pulled up a rough track accidentally exposed some lead-zinc ore. In 1876, lead-silver ore was discovered and mined at Thackaringa, near Broken Hill in New South Wales, but the mines closed in 1877. …
