A Prussian engineer, Jacob Brache was the foremost to feel that quartz reefs may have even more gold than alluvial fields.
More2020-1-13 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.

More2020-6-20 Quartz reef mining proved to be the most widely practised extraction method used in the region; it was undertaken on all the goldfields of central Victoria and continues to be successfully employed to the present day. Quartz reefs were the primary source of gold in most goldfields.
MoreThe Tower Hill or Perseverance reef was actively mined during the early 1870's and prior to 1875 was reported to have crushed 2069 tonnes of quartz yielding 68,195 grams of gold (33 gm. Au/tonne) however at relatively shallow depth (20 metres) heavy water flows were encountered and mining ceased. The reef strikes at 105° and was averaging 0.77 metres in width at the lowest level.
More2019-10-31 discovery and mining of more substantial deep-lead alluvial and quartz-reef gold deposits. Quartz pebbles containing gold were observed during the early alluvial mining and gold-bearing quartz reefs were soon found in outcrop. Experienced miners noted that the reefs and their slaty host rocks greatly resembled those at Bendigo in central ...
More2012-12-29 From my understanding in quartz reef mining, the miners came across these Indicator lines which were small veins of pyrites or thin layers of slate. Around Maryborough, the formation was known as Book Leaf slate (because it resembled the pages of a book). Further to the west (Ararat) the Indicator line resembled a pencil line drawn through the ...
MoreThe project uses heap leach pads which entail production of gold through a heap leach process which is defined as an industrial mining process to extract relatively low grade ores at a comparably low cost. Ruia Mine utilises this benefit to extract the gold from its relatively low grade bulk oxide ore.
More2021-6-11 On the Redan reef the Comet mining company, from a depth of 270 feet, crushed 587 tons of quartz which yielded an average of over one ounce of gold per ton of quartz. 11 Crucial to the development of this fledgling quartz industry were the father and son team of Johann Gottfried Tobias Christopher Ballerstedt and Christopher Theodore Ballerstedt.

More2001-10-1 Gold deposition at Gwynfynydd is primarily associated with the reef footwall. The host veins form a discrete group of structures that may have been emplaced early in the sequence of quartz veins forming the reef.
