Reefs carrying gold and silver values in granite at the Boonoo Boonoo field were associated with base metal sulphides. Some alluvial was won from the Boonoo Boonoo Creek.
In the Poverty Point area gold was sluiced from areas of decomposed granite and a fair tonnage was crushed from several aplite dyke formations. The various workings include the Surface Hill, Tabletop, Big Hill, McLean's Creek and Bonnie Doon. Some patches of better grade gravels were also found in the surface drainage system and alluvial gold was won from these and the Rocky River.
Minerals. Tin dredging has been conducted at Brassington and Boonoo Boonoo Creeks and there has been some prospecting of low grade swampy ground near Timbarra. At Wunglebung, on the Rocky River in very rough country about 30 miles from Tenterfield. A number of pipe formations containing molybdenite, wolfram and bismuth have been worked. A nearby area with some similar features is at Boundary Creek. These formations are generally developed near the granite contact. Other molybdenite shows have been worked in the north of the Tenterfield district near the Queensland border.
The old diggings of Tooloom, Pretty Gully, Lunatic and Macleod's Creek are in this district. Pretty Gully is 14 miles from Drake and the depth of sinking here is generally less than eighteen feet. Goldbearing drift covered by basalt occupies a mountain range near the Clarence River and extends along the northern side of Pretty Gully for about four miles. At least two old river drifts occur beneath the basalt. Gullies in the steep sides of the range have yielded rich narrow runs of alluvial gold. This gold probably derives from the old drifts as no reefs are known about here. Paddy's Flat on the Upper Clarence was a well known alluvial locality.
Gold was produced at a number of mines near Drake including the Adeline, All Nations, Barker's, Beagley's, Great Northern, Kelly's, Red Rock, Kyogle, Lady Hampden, Lady Jersey, Mascotte, Mount Carrington, Mount Pleasant, Pioneer, Sawpit Gully and White Rock. A number of reefs including the Perseverance, Caledonian, and Golden Crown gave some good crushings at Lunatic.
Minerals. In many of the mines listed above the gold bearing oxidised zone gave way to sulphides bearing silver, lead, copper and other metals and this type of ore was mined with varying degrees of success. Other deposits containing copper, zinc and gold occur 10 miles north west of Drake.
The Boorook silver field is about 12 miles north west of Drake. The best producer was the Golden Age where rich silver ores also contained a valuable gold content. Addison's Reef and many others were worked for silver at Boorook.
Antimony ores are known from between Lunatic and Pretty Gully and these are generally gold bearing. Near the former locality there is also an occurrence of molybdenite.
Siliceous iron ores occur near Tabulam.
