  • Alluvial Mining Methods

    As it is my opinion that deep alluvial mining methods in Victoria and in the Murray Flats in New South Wales are practically in their infancy, and considering that we, the old school, of alluvial miners, who have thirty or forty years’ experience to guide us, must in the natural order of things hand over the management of our mines to the younger and less experienced generation of miners, I

  • Quartz Mining Ballarat and District Industrial Heritage

    Within a year of the discovery of alluvial gold in Victoria, some miners were turning their attention to the gold contained in quartz. The development of sophisticated technology really began with the mining and treatment of gold-bearing quartz. The crushing of the rock and the retention of gold from the crushed quartz became a subject of intense experimentation by Victorian miners, as can be

  • Gold Mining Reefs and Leads Ballarat and District

    By the 1860's miners were mining the quartz reefs to extract the gold. In the early days of alluvial lead mining, the miner's had no way of knowing where the ancient creek beds were going, and so shafts were sunk as they tried to follow them underground. It is difficult to pinpoint historical locations which are sometimes given as a lead, for example the Black Lead. As miners followed the gold

  • Gold Mining Alpine History

    From the first discovery of gold in 1852, and with two mines still operating, the Harrietville goldfield has an impressive record of over 160 years of continuous gold production. After the initial phase of alluvial mining in the rivers and creeks, the rich quartz reefs in the surrounding hills were soon exposed. The Rose Of Australia reef was the first to be worked in 1860 closely followed by

  • Gold Earth Resources

    Gold-bearing quartz veins are often grouped into vein systems, which can cover areas of up to 150 square kilometres. Mineralised areas such as these may contain more than 100 tonnes of gold, with typical grades for current large-scale underground mining between 5 and 30 g/t(grams of gold per tonne of ore). The quartz veins that host mesozonal orogenic gold commonly contain minor amounts of

    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.

  • Methods of Gold Mining Geology In

    Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in northeastern Nevada. Other gold mines use

    Alluvial gold was discovered at Angepena Goldfield in 1892 in shallow alluvium within several gullies and adjacent hillsides, particularly Golden Gully and Windlass Hill. By 1894 the alluvials had been worked out and mining commenced on auriferous quartz–ironstone reefs

The tenement areas are located in the heart of Victoria’s Golden Triangle and surround many of the large alluvial gold nuggets located in the

  • Gold Geoscience Australia

    The gold that these rocks contained has been washed down into creeks to form alluvial (placer) gold deposits. Here, the gold is further concentrated by the action of water. Because gold is heavier than most of the material moved by a creek or river, it can become concentrated in hollows and trapped in the bed of the river. These are known as secondary (alluvial) gold deposits and they can be
