This image is a reproduction of an 1899 original depicting the 'Williams Good Luck Mine' on the Mopoke Reef (also called 'Morepork Gully') in the Dingle Ranges, approximately three miles from Beechworth. The foreground of the image is littered with piles of smashed rock and detritus, known as ‘mullock’, beside a reinforced mine shaft, a vertical access passageway allowing miners to enter the mine and haul ore out using lifting technology such as a poppet heads, whims or windlasses. A group of miners and a dog appear close to an open-sided miner’s hut. Following the discovery of gold at Beechworth in 1852, rushes quickly followed at surrounding creeks and gullies in the district. In the late nineteenth and early twentieth centuries, small syndicates of miners continued to work old or abandoned quartz reefs, often persisting without the assistance of heavy machinery to remove the large amounts of rock, in order to obtain yields at ever greater depths. The group of miners in this photograph are Mr. Roger Williams and Sons, who revived operations at the ‘Old Good Luck’ mine on the Mopoke Reef in the Dingle Range near Beechworth around 1892, working the site for more than two decades. An emigrant from Cornwall with experience in the tin mining industry, 19 year old Roger Williams senior sailed to New Zealand in 1840, then to Australia where he spent time in the Bendigo Gold Fields before settling in Beechworth in the early 1860s. Mr Williams senior worked on various mining activities in the district, including the Rocky Mountain Tunnel project. Conversant with the character of gold-bearing reefs in the area, the syndicate dug an eight hundred foot tunnel, digging down as far down as two hundred feet with little capital save their labour, to connect and provide better working access to the mass of reefs and veins in the vicinity. Progress was hampered by poor air quality charged with fumes from dynamite and large quantities of rock had to be crushed to obtain payable yields. The Victorian Goldfields are filled with ruins and remnants of the area's rich mining history, ranging from small alluvial diggings to the remains of huge mining companies. Site names often changed several times throughout the nineteenth and twentieth centuries. Some sites were abandoned and forgotten, others were worked continuously over many decades. The names of mines were often repeated at different locations throughout the Victorian Goldfields. For example, there is a Mopoke Gully heritage mine near Fryers Creek, Victoria. 'Mopoke' is a common onomatopoeic name for Morepork and Australian Boobook owls. This image has historical, social and research significance for patterns of emigration during of the Victorian Gold Rush, and the historical, social and environmental impacts of mining at Beechworth at the turn of the nineteenth and twentieth centuries. As gold became scarce and government support and large company investment waned, poor hard-working miners laboured intensively to make a living through periods of high unemployment. This image can be compared and studied alongside other historical mining photographs and objects in the Burke Museum Collection. It has potential to improve our understanding of miners working conditions and the shifting character of mining in the Beechworth district.

This photograph dates to 1899, towards the end of the gold rush in the Mopoke Gully area. A large opening to a mine can be seen behind the men in the photograph, with a wheeled cart on a track leading to the men's position, where the soil and rocks have been hauled away. This photograph interestingly contains dogs alongside the miners. While dogs have been recorded as deterrents to thieves in the Victorian goldfields, these dogs appear as companions to these men. Mopoke Gully mines came under the 'Fryer's Creek' division of the Castlemaine District during the Gold Rush. After the Gold Rush began in Victoria with the discovery of gold at Ballarat in 1851, Gold was found in Castlemaine by December of that year. 20,000 diggers were spread across the Castlemaine region, and the area was yielding about 23,000 ounces of gold per week. Mopoke Gully was the site of the Mopoke Gully Water Wheel, operating under the Bendigo and Fryers Goldmining Company from 1887 until 1900. This Water Wheel was used in the gold mining technique of 'sluicing'. Hydraulic sluicing uses high pressure water jets to blast away the earth, which runs through a sluice box, catching the gold with all remaining slurry washing away. This Water Wheel was built the same year as the more famous 'Chewton Water Wheel', but was smaller in diameter (60ft as opposed to Chewton's 72ft). The Mopoke Water Wheel ruins are quite intact today, and are a registered archaeological site. The search for gold is ingrained into the history of Victoria and therefore, images like this one 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 1899. This photograph reveals important information on the use of dogs on Victorian goldfields in 1899. Dogs were used both as companions, such as this photograph depicts, as well as deterrents to thieves.

This photograph dates to 1899, towards the end of the gold rush in the Mopoke Gully area. A slurry of rocks after they have been broken up is depicted, and this is part of the hydraulic sluicing mining process. Four men are relaxing under a wooden structure, with a fifth bearded man standing near a stone wall. This photograph interestingly contains dogs alongside the miners.

In Australia, precious opal is found in Cretaceous age sandstones and mudstones. These sedimentary rocks were deeply weathered and this weathering released silica into the groundwater.Australia is the only part of the world where opalised animal and plant fossils have been found. Opal artefacts several thousands of years old have been discovered in East Africa. As early as 250 BC the Romans prized opals, thought to have come from mines in Eastern Europe, the ancient world's main source of opals. There are many aboriginal dreamtime stories that feature opal. Australian opals discovered during the late 1800's found little favour with European markets but their commercial value increased in the 1900's and in 1932 Australia took over as the major producer of opals in the world and remains the largest producer to this day. Opal is found around the world (Brazil, Mexico, Honduras and the western US) however Australia produces 95% of the world's precious opal and it is our official national gemstone. Opal was first mined commercially at Listowel Downs in Queensland in 1875 and later at White Cliffs in NSW. Today, Coober Pedy (SA) is the main producer of white opal, though in recent years this field has expanded and all types of opals are found. Other centres in SA include Andamooka and Mintabe. Lightning Ridge (NSW) is renowned for black opal and formerly White Cliffs was a large producer of high quality opal. Boulder opals (opals in concretionary ironstone) are mined in Queensland from numerous localities in a zone extending from the Eulo and Cunnamulla district in the south and northwest for a distance of over 700 km to Kynuna in the north. The towns of Quilpie, Yowah and Winton are the main opal mining and wholesale centres. Opals are considered gemstones and have been used in jewellery for thousands of years.Throughout much of history, opals were actually believed to be good luck. The Romans thought that opals were one of the luckiest gemstones and a symbol of hope. In the Middle Ages, opals were believed to be bestowed with all the positive properties of coloured gemstones due to its rainbow-like play of colour. Finally, there is a superstition that you should not wear an opal unless it is your birthstone otherwise misfortune will befall you. This, of course, is far-fetched, but the notion could have been promoted in the late 19th and early 20th Centuries by diamond traders who were trying to increase sales of diamonds and deter people from buying opals. Possibly related to this is the thought that you should set opal jewellery with diamonds as their powers of good fortune will override any negativity held by the opal. The great majority of opal does not show play of colour and is called common opal or potch however this is not the case with a precious opal. Opal is a precious gemstone, like rubies, emeralds or diamonds. Opal is rare, and it is expensive to prospect and mine for.Silica is one of the most common minerals on the planet, but precious opal is very rare – far more rare than diamonds. Precious opal is rare because the natural processes that create it rarely occur.Most (at least 95%) of the opal found by miners is common opal without gem colour. In Australia we call it potch. It can be white, grey, black or amber coloured. Even when a miner finds gem-coloured opal, most of it can’t be cut into gemstones because it’s too thin, or sandy. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.It is not known where this opal originated, except that it is probably from Victoria, as it has been recorded from many localities in the State. Common Opal is formed from silica-rich water circulating through rocks near the Earth’s surface. It consists of minute spheres of silica arranged in different ways. In common opal, the spheres are of different sizes and randomly arranged, unlike in precious opal where the spheres are of similar size and uniformly arranged in three dimensions. These differences account for common opal generally being translucent to opaque and without the play of colours, or opalescence, displayed by precious opal. Common opal is found in many localities and different geological environments throughout Australia and the world. Precious opal requires special conditions to form and is much less common. Australia produces most to the world’s precious opal. burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, precious opal, opal, brazil, mexico, honduras, queensland, coober pedy, gemstones, jewellery, play-of-colour, light blue
