An 1857 Royal Commission into the progress of the Victorian goldfields supported Murchison's view that mining of the Bendigo quartz reefs would be shallow and shortlived. Miners on (and under) the ground, however, were disdainful of the views dispensed by scientific mining men on the other side of the world.
Quartz. Quartz is one of the most common minerals in the Earth's crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO 2), having a specific crystalline form (hexagonal).It is found is all forms of rock: igneous, metamorphic and sedimentary.
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.

discovery and mining of more substantial deep-lead alluvial and quartz-reef gold deposits. Quartz pebbles containing gold w ere observed during the early alluvial mining
Ore from reef mining ventures was commonly crushed in a stamp battery like this one near Mogo before being treated chemically to extract the gold. Power for the stamp batteries was often provided by traction engines with a belt and pulley system or by waterwheels. Note: • Only a snapshot of historical mining information is presented here.
Reef mining. A third kind of gold mining was reef mining. Layers, called reefs, of quartz rock containing gold are found deep in the earth. Quartz is a hard, white rock. Deep shafts and drives had to be dug, and all the rock dug out had to be hoisted to the surface. Big engines hoisted lifts for the miners and buckets of gold from the shafts.
Quartz Mountain Geological Reserve, also known as Amherst Reef, Big Reef and Big Hill Reef, is an impressive reserve in Lillicur, not far from Talbot VIC. The reserve features the largest outcrop of pure quartz rock remaining in Victoria. The reef forms a north-south ridge approximately 0.8 km long. Huge masses of quartz stand over six metres high and in one spot a massive forty tonne boulder ...
Silica (silicon dioxide, SiO 2) occurs as the mineral quartz, a major constituent in many igneous and sedimentary rocks, and the most common detrital mineral in sandstone.As a commodity, the term silica is applied to quartz in all its forms — as vein or reef quartz, quartz pebbles, sandstone, quartzite, or as unconsolidated sand.

At the Palmer Goldfield, a gold-bearing reef was found in 1854 and sporadic mining occurred until 1938. Auriferous quartz veins are hosted by the Palmer Granite; some gold was won from alluvial diggings. Total production for the field is ~1.6 kg. Other gold mines in the Kanmantoo Trough include Lady Jane, Grundy, Kohinoor, Cygnet and Rainbows End.

Reef mining in the district started in the late 1850s, but at this site a gold bearing quartz reef was first discovered in 1887 and "The Jubilee Quartz Mining Company" was formed. The mine commenced operations shortly thereafter and continued under various names until 1913 when shareholders closed the mine and sold the plant and equipment.
The Jubilee Company Quartz Gold Mine is archaeologically important for its potential to yield artefacts and evidence which will be able to provide significant information about the technological history of gold mining.
