Quartz reef mining - Wikipedia

Quartz reef mining is a type of gold mining in "reefs" (veins ) of quartz. Quartz is one of the most common minerals in the earth's crust, and most quartz veins do not carry gold, but those that have gold are avidly hunted by prospectors. In the shallow, oxidized zones of quartz reef deposits, the gold occurs in its metallic state, and is easily recovered with simple equipment. Quartz reef mining played an important role in 19th century gold-mining districts such as Bendigo, Victoria, Central Otagoin New Zealand, and the C

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 ...

Vein (geology) - Wikipedia

Veins are of prime importance to mineral deposits, because they are the source of mineralisation either in or proximal to the veins. Typical examples include gold lodes, as well as skarn mineralisation. Hydrofracture breccias are classic targets for ore exploration as there is plenty of fluid flow and open space to deposit ore minerals. Ores related to hydrothermal mineralisation, which are associated with vein material, may be compose
