This picture is dated to 1906 and depicts an open cut sluicing site located in El Dorado captured looking west from the No.1 Bedrock Site. Sluicing was undertaken in the area from 1900 to 1942 with some short breaks between these periods. The image depicts a location mined by Cocks Pioneer Gold and Tin Sluicing Company (as recorded on the annotation on the card mount). It portrays open cut rocks with a crevice in the center of the image where the sluicing was being undertaken. The Cocks Pioneer Gold and Tin Mines N.L was one of El Dorado's two largest open cut sluicing mines of the 20th Century. The other was named the Cocks El Dorado Gold Dredging Company. The Cocks Pioneer Mines operated from 1901 until 1941 and found a total of 117,378 ounces of Gold and 1,673 tones of tin concentrates over these years. The Cocks company was formed in 1898 and operated until 1941. 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 gold and other precious metals. From 1914 , four years after this image was captured, the company reformed to Cocks Pioneer Gold and Tin Mines NL (previously it was known as Cocks Pioneer Sluicing Co) and undertook large scale sluicing operations until 1929 and then 1934-1941. El Dorado is located on Reedy Creek and is surrounded by forested country to the north and east. It is 20 km east of Wangaratta in Victoria's regional north-east. John Cock was the son of a Cornish minor who arrived in El Dorado in 1858. Cock founded his gold and tin mining company which ran successfully for many years in the El Dorado region. It was an open cut sluicing company because of the abandonment of underground mining after this was deemed too dangerous. In 1935 Cock's El Dorado Company commissioned the floating dredge which is still visible in El Dorado today. The dredge was built by the Thompson engineering works, Castlemaine, and weighed over 2,000 tones and today has a place on the Victorian Registers of historic buildings. Interestingly, the name El Dorado does not derive from the gold in the region, but from the Barambogie pastoral run completed by William Baker in 1840-1841. Gold was discovered in El Dorado 1854 but the gold was too deep for individual prospectors to find, it required the use of heavy machinery.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 in 1906. 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 El Dorado, a small regional location near Wangaratta 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 El Dorado which can be analysed and studied alongside images like this one.Sepia coloured rectangular photograph printed on gloss photographic paper mounted on board.Obverse: COCKS PIONEER Q + T SL CO, N.L. / 1906 / No.1 BED ROCK SITE LOOKING WEST Reverse: 1997 2612 A02612el dorado, north east gold, sluicing, gold sluicing, hydraulic sluicing, gold and tin mine, open cut mining, mining, gold mining, north-east victoria, beechworth, burke museum, 1906

This photograph dating to 1910 depicts an open cut sluicing site located in El Dorado captured looking east up the open cut from the number 3 Barge site. Sluicing was undertaken in the area from 1900 to 1942 with some short breaks between these periods. The image depicts a location mined by Cocks Pioneer Gold and Tin Sluicing Company (as recorded on the annotation on the card mount). It portrays open cut rocks with a crevice in the center of the image where the sluicing was being undertaken. There is a small timber structure on the right of the image which could be an entrance to a mine or supports made of wood to prevent a cave in at the open cut site and above the cut rock there is bush. The timber structure has rail tracks on top of the bridge which could suggest the identification of this structure as a mine entrance. The rail tracks were used for little carts which hauled soil from the mine. The Cocks Pioneer Gold and Tin Mines N.L was one of El Dorado's two largest open cut sluicing mines of the 20th Century.

The Cocks Pioneer was an extremely successful mining company during the 20th century. In the Annual Report of the Secretary for Mines for the year 1915, the Cocks Pioneer was the largest producer of gold and tin collecting 5,535 ozs. of gold and £7,500 of tin. Twenty years later in 1935, Cocks Pioneer was still one of the most profitable mines in Victoria, ranking as the second-highest dividend paying mine. The company produced a total of 3,650 kg of gold.

This photograph depicts Cocks Pioneer Gold & Tin Sluicing Company, N.L. (no liabilities) site No.3 and is looking from the east side of the site. The image is captured within a small valley creek bed and presents the conditions in which mining was evolving in the early 1900s. In the foreground are remnants of components such as flume pipes, timber and iron pieces, mixed with rocks and rubble. These appeared to have connections to the small processing sluice plant featured in the background. The scale of the processing plant appears to be relatively small with the structure resembling a shack or cottage built from iron and positioned upon a floating pontoon. This is known as dredge sluicing, essentially a floating factory, that was capable of covering large areas of the lake and dams. As this dredge was compact it could maneuver in tight spaces, which larger structure could not. The size of the figures at the front opening, which appears to be a doorway, indicate the scale of this very modest production plant. Scaffolding on the roof and to the left process alluvial from the stream floor into sluicing boxes, which filtered deposits passing over a series of ripples to collect the heavier material such as gold.
