Two quartz reefs were mined within this epithermal system until the 1930s, with over 43,000 oz of gold extracted from shallow surface and underground workings. Massey Reef is part of the historical Muirs Reef gold mining area. Recent significant surface trenching results in outcropping and subcropping quartz veins are shown in Table 3.

Goldbearing quartz reefs commonly show extremely erratic and unpredictable grade variation, although gross geological continuity may be good. This type of variation is often described as being nuggety or having a high nugget effect and can be measured quantitatively using the semivariogram. Understanding of geological features such as reef texture and structure will provide improved models ...
The difference between 19thcentury and 21stcentury mining techniques and the type of ore sought is based on the grade of material being mined and the methods of mining which are used. Historically, handmining of gold ores permitted the miners to pick out the lode quartz or reef quartz, allowing the highestgrade portions of the lodes to be ...
Although at this time alluvial mining was the primary method of gold recovery, the Tambaroora fields also supported the earliest attempts at reef mining in Australia, over fifteen years before the reef mining boom of the 1870s. The Quartz Roasting Pits Complex is one of the oldest goldrush sites in Australia and represents one of the first ...
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.

History of mining The Hill EndTambaroora Gold Field was one of the richest gold mining areas in NSW, and the first reef mining area in Australia. Gold was discovered in 1851 at Golden Gully, when prospectors worked their way north east from Ophir, where the first alluvial gold mining in Australia had commenced a few months previously.

Understanding of geological features such as reef texture and structure will provide improved models for the interpretation of assay data, drill core descriptions, etc. In this paper, a case study from the quartzhosted gold occurrences in the Gwynfynydd mine, United Kingdom, is described.
Quartz. Quartz (SiO 2), a common mineral, is the product of the two most prevalent elements in the earth''s crust: silicon and can be found as giant crystals or small grains, and is the main component of most types of is the hardest common mineral, and for this reason is often used in the making of sandpaper, grindstones, polishers, and industrial cleaners.
