  • Quartz reef mining Wikipedia

    Quartz reef mining played an important role in 19th century gold-mining districts such as Bendigo, Victoria, Central Otago in New Zealand, and the California mother lode. In at least the shallow, oxidized zones of quartz reef deposits, the gold occurs in its metallic state, and is easily recovered with simple equipment. A "reef" is another term for a vein of some mineral or ore, and has nothing to do with biological reefs (bioherms), such as coral reefs. Quartz is one of the most common minerals in the earth's crust, and mo

  • Quartz Reef Mining, Mining Techniques, Surface Mining

    Quartz Reef Mining. Primary gold typically happens in quartz veins. The removal of gold ore from these tough quartz veins was traditionally referred to as quartz reef mining. A Prussian engineer, Jacob Brache was the foremost to feel that quartz reefs may have even more gold than alluvial fields. The novel mining firms had to sink very profound shafts to get quartz from the reefs profound

  • Talk:Quartz reef mining Wikipedia

    Quartz reef is an archaic mining term for a quartz vein which contained gold. The reef has nothing to do with coral reef, but rather a resistant layer of hard quartz. I think the terminology originated in the Australian gold fields, but is also used in mining reports from South Africa (the Merensky Reef) and elsewhere. Quartz reef mining or lode mining won gold

  • Gold Mining Reefs and Leads Ballarat and District

    A gold reef is where the gold is found still deposited in its original rock host. In Ballarat this rock was usually quartz, in what is described as a reef. Alluvial gold was gold that had come loose from its original host, and had been deposited by water action into creeks and rivers. Over time, many of these creeks and rivers were covered over by later geographical changes and became buried

  • Gold Gold Trails

    Reef mining operations typically started as small scale ventures between syndicates of two to six miners who would peg out their claim and start mining down the line of a quartz reef. As reefs rarely went straight down, this work usually required a shaft to be sunk first up from where drives could be put in to work the reef at different levels.

    The reef was reported to be very rich large blocks of reef-quartz, put on display in Grafton in January, 1873, were "thickly impregnated" with gold, however, owing to logistical difficulties no material was ever crushed.

    29/12/2012· (Reef / hard rock mining) It had me stumped for awhile how if most quartz (not all) reefs run roughly in a NNW SSE in Victoria and 'Indicator' lines run in this same direction, how could they meet ? Because when a indicator line intersects a quartz reef gold is found. I was then informed by a knowledgeable chap that most quartz reefs have 'spurs, fingers, veins, offshoots' which formed
