Alluvial gold was discovered at Teetulpa in 1886 by Thomas Brady and Thomas Smith. Reef mining soon commenced, but the reefs were narrow and low grade and only worked on very small scale. Teetulpa Goldfield is predominantly alluvial, from erosion of NS trending quartz sulphide reefs which cut across flaggy, well laminated siltstone of Tapley Hill Formation. Gold was reportedly found in sandy wash near the base of the alluvium, main alluvial leads representing fossil valley stream bed accumulations slightly offset from the main drainage. Within the first 4 weeks following discovery, the number of diggers on the field increased to 2 000 and at its peak the population was estimated at 4 000 - 5 000. Production is unknown. In 1908, Brown estimated that the total value of gold from the field was 300 000 pounds, equivalent to 100 000 ounces (3.1 tonnes). The largest nugget, The Joker weighed 29 oz 15 dwt (925.5 grams). After 1 year production was sporadic. Further attempts at underground mining were made in 1911, 1913 and 1934 and several companies have carried out reconnaissance exploration since 1966. Small scale mining activities are in progress.
