There is another copy of this postcard (VEMUP1039) in the collection. It is part of Melbourne's V.S.M. (Victoria Stamp Market) Series, printed in Prussia, Germany alongside several similar hand-coloured postcards in our collection. This postcard is believed to originate from c. 1900-10, but the image itself - of sluicing for gold on Menzies Creek - might be older. Gold mining in Emerald was most popular in the 1850s and 60s. However, gold mining on Menzies Creek reopened in the 1890s depression, which is a more likely source of this photograph.This postcard is significant for its relative uniqueness as a colourised depiction of Emerald's gold mining history.This postcard is separated into two pieces of paper (between the obverse and reverse). The reverse is a landscape message side with not message but some annotation and an accession number written to the left side, in a portrait orientation. The obverse is in a portrait orientation, with a printed caption in the bottom-right. The image is hand-coloured (colour artificially applied to a black-and-white base photograph) and depicts two men (one of whose head is cut off by damage to the photograph) working in an artificially reinforced channel in what appears to be a creek or stream. One stands in the water while the other is beside it. In the background, the scene fades up the hill into a forest.Obverse, Printed Caption: "Hydraulic Sluicing, / Emerald near Gembrook" Reverse: Printed Vertically: "Printed in Prussia" Printed Horizontally: "elbourne" Handwritten Annotation: "Prospect Bend along the / Menzies Creek near / Emerald Kallista Rd. / GOLD"emerald, 1890s, gold mining

This photograph dating between the 1850s and early 1900s depicts an open cut sluicing site located in Allan's Flat looking upon the open cut from Staghorn Flat Number 1. Sluicing was undertaken in the area from 1850 to 1904. The image depicts a location mined by Yackandandah Sluicing Co. It portrays and open space with pipes laying on the ground and connected to pipes leaving the barge. These pipes were used to wash and seperate the qaurtz. There are two small buildings on high ground over looking the barge. Yackandandah Sluicing Co. was created by J.A. Wallace in the 1880s. The Yackandandah Sluicing Co. operated from the mid-1880s to the early 1900s, when resources eventually ran out. Open cut sluicing involved the use of high-powered hoses which used the centrifugal sand pump system (known as hydraulic sluicing) which broke down the soil which was then processed for quartz, gold and other materials. After the resources where drained, Wallace reaped the benefits of his mining business. Allan's Flat is located on the Yackandandah Creek, and is 10km north-east of Yackandandah and 20km south of Wodonga in Victoria's regional north-east. Allan's Flat was initially used to mine gold through alluvial methods, however that came to an end with little results. The mining business was then revived by J.A. Wallace with the introduction of hydraulic sluicing.The search for gold is ingrained into the history of Victoria and therefore, images like this one which portray an open cut sluicing site can reveal important information for society and technology for the date when the photograph was taken. This image is of important historical significance for its ability to convey information about sluicing and the methods used to find gold and other minerals in the lat 19th Century. It also shows a location where sluicing was undertook which provides insight into the impact of sluicing on the environment at a time when it was done. This image is important for current research into the history of Allan's Flat, a small regional location near Yackandandah in Victoria's North East. Therefore, this image has the capacity to be beneficial for research into society and the motivations of those living and working in this region during this period and therefore, has social significance. The Beechworth Burke Museum has additional images relating to gold sluicing and Allan's Flat which can be analysed and studied alongside images like this one.Sepia coloured retangular photograph printed on gloss photographic paper mounted on board.Revers: Sluicing at Allan's Fortallan's flat, north east gold, sluicing, gold sluicing, hydraulic sluicing, mining, gold and quartz mine, beechworth, burke museum, yackandandah

While gold was discovered in Emerald in 1858, mining and alluvial gold sluicing on the Menzies Creek reopened in response to the 1890s depression - one of the largest economic crises in Australian history, from which the economy did not significantly recover until after the end of the 1895-1903 drought. This photograph, dated to around 1900, likely originates from this period of activity. Sluice boxes are effectively artificial channels with riffles at the bottom to disrupt the current and take gold out of suspension; the heavier gold sinks to the bottom and remains in the box while lighter material flows out. This photograph was taken at Prospect Bend, which appears to have been north of Emerald between A'Vard Park and The Patch. There is another larger copy of this photograph in the collection.Gold mining was an important part of the region's early economy, and this photograph captures a major method of extracting gold from the land and water.This item is a black and white photograph taken from the direction of flowing water as it runs over a gold sluice. In the foreground the banks of the creek are covered in grass and shrubs, before transforming into earthen slopes after the water drops down; the gold sluice is in the water towards the background, where the creek turns left. Behind the sluice, the far bank of the river is covered in logs, ferns, and shrubbery. The reverse of the photograph features handwritten annotation in pencil, including an accession number.Reverse, pencil: "Prospect Bend / [crossed out] Emerald Park[?] / 10 / Sluicing for Gold. / near Menzies Creek + Monkey / Dung Creek / near (A'Vard Park) / Creek / Flows into Leigh Aslings Dam then / out again"emerald, menzies creek, gold mining, 1900s, 1890s

The first discovery of wolfram in this location was in 1894. The first claims were lodged in 1908 and then with the start of World War I the value of tungsten increased and more claims were lodged and worked. After the war the use for tungsten diminished and the mine was abandoned until World War II when tungsten again became a valuable commodity. However due to difficulties encountered in the mining of the tungsten at the Wilks Creek mine, it was unable to pay its way and at the end of 1943 the mine closed. The viability of mining wolfram at Wilks Creek was again reviewed in the 1960s but with little success. Once again, in 1980 it was reported that there would still be wolfram to be mined but the environmental impact to an area of outstanding natural beauty was deemed to be too great to continue with the project.wilks creek, wolfram mine, wolfram, tungsten, marysville, victoria, mt bismark, wood's point

Cocks Pioneer, East El Dorado, early 1920s. Cocks Pioneer Electric Gold & Tin Mine Company was formed in 1899. The company's first power station, located at the eastern end of the valley began operating with its 340 Kilowatt steam-powered generator. By 1909, from 2 500 000 cubic yards worked, reported recovery was 17 284 ounces of gold and 224 tons of tin ore. By 1909, Cocks Pioneer’s power plant had become inadequate and uneconomical. The barge was floated downstream about a mile, but lost time caused the operations to cease. Following testing, a new mine was established by diverting Reid's Creek at a cost of £25 000. Settling dams were built, one of which held 1 935 900 cubic feet. Sold earth banks, built against a wall of stringy bark saplings constructed and laced with vertical props, were built. In 1914, the company was reformed as Cock’s Pioneer Gold and Tin Mines NL, another power station was constructed at the western end of the township, near the junction of Clear and Reid's Creeks. From 6,800,000 cubic yards of material processed, the returns were 64 397 ounces of gold and 855 ton of tin. Cocks Pioneer mine then moved the barge downs stream and continued sluicing. In 1929 Cocks Pioneer Electric Gold and Tin Mining Company ceased operations due to a drop in values.

This photograph depicts mining operations (in particular, hydrolic sluicing) at Three Mile Mine, Barramutha, during the later periods of mining, 1920s-1950s. Three Mile Mine was a major site of mining activity sating back to the 1850s, although was often not as prosperous as other sites such as those situated on the Woolshed Valley. Many miners would leave Three Mile Mine for better prospects on other claims. The main, most successful 'rush' at Three Mile Mine occurred during and immediately following September 1855. This photograph, however, depicts a much later period.The search for gold is ingrained into the history of Victoria and therefore, images like this one which portray a miner at a sluicing site can reveal important information for society and technology for the date when the photograph was taken. This image, and its related images, it important for its historical significant of labour and mining extraction used for gold during the latter gold rushes in the 1900s.

This image shows an unknown location in the area of Beechworth that was possibly used as a sluicing mining site for gold during the Victorian Gold Rush. This era saw an influx of Chinese immigrants and Australian prospectors hoping to strike it rich on the fields. Many companies such as the Rocky Mountain Extended Gold Sluicing Company Ltd and the Cocks Pioneer Gold &Tin Sluicing Company also set up mines in the area. This site may be the location of one of these company's mines. The wooden logs are reminiscent of known sluicing operations in the era from that time. Sluicing involved the use of high-pressured hoses to clear away soil from earth that had been dug up by miners and was a popular method of excavation in the area, although it had severe impacts on the environment.The search for gold is ingrained into the history of Victoria and therefore, images like this one which portray an open cut sluicing site can reveal important information for society and technology for the date when the photograph was taken.

This image taken between 1920-1930 depicts open-cut hydraulic sluicing at the Three Mile Mine, located about five kilometres south of Beechworth. Alluvial, or surface, mining began on this site in the 1850s, but was soon replaced by hydraulic sluicing methods. By the start of 1880 it is estimated that nine hundred miles of water races had been cut though soil and rock in the Beechworth district. Hydraulic sluicing employs high pressure jets of water to blast away large areas of earth and wash it down to be run through a sluice box. Gold gets caught in the sluice and the remaining slurry is washed away. Large water quantities were required for hydraulic sluicing, and the long water races and deep tailraces that were constructed were considered great engineering feats. This method of mining is extremely effective, but causes significant environmental damage and impacts to waterways and agricultural operations. Miners at Beechworth built extensive networks of races and dams to secure reliable supplies of water on a scale far greater than elsewhere in Victoria. By the 1880s Beechworth's water barons continued to hold more than half of all the water right licences on issue and undertook sluicing operations on a massive scale. The manipulation of surface and ground water via race networks was well planned and recorded in detail by local mining surveyors. The maps that were created, combined with modern geo-spatial technologies, provide a vital key in understanding the great lengths to which miners went to capture and control critical water resources. Today, Three Mile mine is called Baarmutha. The Three Mile Mine was unproductive until 1865 when John Pund and three other miners secured a fifteen year license and constructed a water race from Upper Nine Mile Creek to Three Mile Creek. In the early twentieth century Pund & Co. averaged over one thousand ounces of gold per year from the mine. After Pund's death in 1915, GSG Amalgamated Co operated the site, continuing sluicing until 1950. This image of hydraulic sluicing methods shows the extent of water-works engineering in the landscape. This photograph has historic and research potential for understanding changes to the landscape, the evolution of mining methods, and the extensive construction, manipulation and management of water networks in the Beechworth district.

This photograph depicts mining operations within the Beechworth area, in an unidentified valley where sluicing was utilised as a method for extracting gold from the environment. After gold was discovered in the region in 1851, sluicing became a characteristic of gold mining in the region - "Ovens miners carved intricate networks of races" throughout the region - involved the diversion of water in many channels, or water races, which contained inbuilt 'ripple devices' designed to trap gold for later extraction. By 1871, 900 miles of water races had been cut into the Beechworth Mining District. As suggested by the numerous figures involved in labouring along the water race, sluicing was a source of considerable employment within the region. This image is of important historical significance for its ability to convey information about sluicing and the methods used to find gold in the 1850s, and provides clues as to how sluicing and the widespread construction of water ranges changed the environment of the region. This image is important for current research into the history of the Ovens region in Victoria, which played such a prominent role in the early Australian gold mining industry. Therefore, this image has the capacity to be beneficial for research into society and the motivations of those living and working in this region during this period and therefore, has social significance. The Beechworth Burke Museum has additional images relating to gold sluicing and and the mining activities in the area more generally, which can be analysed and studied alongside images like this one.A black and white rectangular photograph printed on matte photographic paperbeechworth, mining, miners, labour, water race, sluicing

This photo shows the large mining cavity with a hydraulic sluicing machine in operation at Baarmutha Three Mile Mine, Beechworth . The Beechworth Mining District was one of six mining districts established by the Governor-in-Council on 4 January 1858 under the provisions of An Act for Amending the Laws Relating to the Goldfields (21 Vic no.32). The District was further divided into seven divisions: Spring Creek, Snake Valley, Three Mile Creek, Buckland, Woolshed, Yackandandah and Omeo. The boundaries of each of these divisions and of the whole district are described in the Governor-in-Council's proclamation printed in the Government Gazette, 5 January 1858, pages 3-5. Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.This photograph shows the impact the gold rush era had on Australia and the earth.A black and white rectangular photograph printed on photographic paperCopied from original on loan film (WEBB QLD) / Donated 2009 NOV/ Baarmutha Three Mile Mine c1920-1950/ Managed by John Weir Peter Jereen Jack Cox / Owned by Plain Bros then Parkinsons Sluicing.mining, gold fields, beechworth, gold rush, burke museum, photograph, mining cavity, hydraulic mining, hydraulic sluicing, baarmutha

This photograph depicts a man in dark clothing, standing in front of a cut away section of earth. He is undertaking hydraulic sluicing, which involves the use of high powered hoses, in order to cut away the earth which can then be sifted for gold. There is a single tree in the background and the earth contains numerous signs of damage because of the mining. Beechworth become a mining settlement after the discovery of gold in 1852. Gold fever had already spread across Australia's colonies and the American states. Sluicing the landscape for gold, as shown in this photograph, was done by diverting water and washing away the lighter dirt, allowing the gold particles to sift down in to catchments for collection. In Beechworth, there was considerable discontent caused by attempts to restrict water use for sluicing to those with certain 'water rights'. The extensive use of hydraulic sluicing, and the washing away of top soils has continued to impact the surrounds of Beechworth in to the present day. Sluicing as a method for gold mining which was widespread across Victoria during the 1870s. The erosion of the top soil in search of gold has a continuing environmental impact on the landscape and this photograph depicts but one example of this occurring and can provide much information to a researcher interested in understanding the history of gold mining in Victoria. This image of the miner and hose is historically important because it demonstrates the methods of goldmining employed in the later years of the goldrush at Beechworth. It shows how much land is washed away by the use of this technology. The image has good interpretive capacity because it allows researchers to see a different mining technique to what is usually presented.
