Donald Clark Collection.A notice for a public meeting about the future of small scale mining in Victoria. Held at Tarnagulla Hall on 30th April 1986.

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 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. 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.

Diggers & Mining. Getting the Gold. Slide: On some fields, but notably at Ballarat and Daylesford, the diggers soon began building water races from streams and springs, and running the race water into small reservoirs near their claims. (Water races, as we have seen, were also constructed all over the Ovens field for sluicing purposes.) Later in the gold decade, the building of water races went on space - chiefly by large co-operative groups of diggers engaged in small scale mining operations. Markings: 69 994.LIF:4.

This image shows the approach to Beechworth from the south-west via the Newtown Bridge. Numerous early buildings line the road as it bifurcates to become Ford and High Streets on the ridge above Spring Creek and Newtown Falls. The sloping, rocky terrain and water course along the gorge show evidence of the intense mining activity that occurred at the site. The Ovens Gold Rush at Beechworth started when gold was found at Spring Creek in February 1852, prompting an influx of miners from around the world. The population grew over 20,000 by 1857. While the earliest mining at Beechworth was similar to that in other Victorian goldfields like Ballarat and Bendigo, Beechworth is notable for its use of hydraulic sluicing as a major method of removing wash-dirt. 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. This method of mining is extremely effective but causes significant environmental impacts and damage to waterways. Large water quantities were required for large-scale sluicing, and the long water races and deep tailraces that were constructed in the Beechworth area in the nineteenth century are nonetheless considered feats of engineering. The site in the photograph is associated with the Rocky Mountain Mining Company who constructed an eight hundred meter tunnel under the township between 1876-1880 to reduce water levels at Spring Creek, which had been subject to diversions since the earliest days of alluvial mining. Over four million ounces of gold (115 tones) were found at Beechworth between 1852 and 1868, and the wealth from the gold rushes built Beechworth and the nationally significant buildings that remain standing today.This image shows the early development of the Beechworth township above Spring Creek, where gold was discovered in 1852. Evidence of hydraulic sluicing, a uniquely predominant method at Beechworth, and water-works engineering are present in the landscape. By the 1870s, alluvial gold deposits were depleted and increasingly complex engineering was required so deeper shafts could reach bedrock. This image is significant for understanding changes to the landscape and the evolution of mining methods and engineering practices related to the extensive construction, manipulation and management of water networks. The shift from smaller scale alluvial mining to larger company dominance in the mining industry has implications for understanding wider social, economic, political and industrial changes in the region of Beechworth and within the context of the Victorian Gold Rush more broadly.

Historically this item would have been used by gold miners, rabbit shooters, mobile "Rag and Bone" traders and other mobile(in caravans and/or horse drawn cart) traders of various small goods and haberdashery. Although marked as not to be used as trade, the isolation and sometimes difficult terrain rules out using larger and more delicate scales. In the early 1900s rough roads and severe weather conditions forced traders to be more flexible in trading with weights and measures. The "close enough is good enough" doctrine was the Australian outback rule of thumb.The significance of this item in the Kiewa Valley during this period demonstrates the slower acceptance of accurate trading measure using the country side principle "my hand shake is my bond". In the Kiewa Valley small quantity commercial undertakings e.g. gold mining, fur pelts and rabbit meat trade did not require bulk weight type scales. Commerce in rural production e.g. fruit and vegetables involved more farmers and their staff in a barter and/or "in kind" payments. This was more so in the depression years 1929 to late 1930s. Self sufficiency was to a large extent more attainable in this region than in the city/ large country town environment. The Australian "fair go" ethical approach to life and commerce was very much ingrained in those living in country regions, like Kiewa Valley as is demonstrated by the not so accurate hand balance, spring loaded scales.This brass "faced" portable Pocket Balance ( Fish Scales) has front plate made from thin pressed brass. The mild steel spring mechanism enclosed by black painted medium gauge steel cover( three quarters cylindrical). Front scale face and rear spring casing fastened by three rivets. Spring loaded marker blade is located in the centre of the front plate. A steel " finger holder" ring is attached at the top of the scale unit from one of two pre drilled holes. The top is for holding the scale upright and the bottom for a hook to dangle the item to be weighed from the bottom.

Invented by a member of the Abbott family of Bendigo, scalebuoys came in various sizes and had a variety of uses such as the mining industry to prevent scale build up in boilers, automotive for car radiators and domestic for water purification. Its essential part is a sealed glass bulb containing a small amount of mercury and a combination of gases.This particular variety was made to be connected to a water tap with a screw attachment and a small outlet pipe. Scalebuoy sent to Alan Cowling from work colleague, Pat Curran in Tasmania. Pat Curran was working as the CEO of a retirement village and found the scalebuoys in the equipment there. Noting the Bendigo manufacturing logo, he decided to send it to Alan. The original owner of the scalebuoys is unknown.sciences, instruments - general, scalebuoy

Troy ounces are slightly heavier than avoirdupois ounces that we commonly use. 1 troy ounce equals roughly 1 1/8 ounces and is used for the weighing of precious metals and gems. It is believed that the troy ounce dates back to the 16th century to the town of Troyes in Frances. This was a major trading centre for Europe and a standardised for of weights was needed. One troy ounce equalled 480 grains of barley.Four circular Troy weights - three have raised outer edge/lip with weight details imprinted in the centre. Large weight has the number 2 embossed in the middle. Second has the number 1.0 in the middle third has the number 1/2 in the middle. Fourth weight is solid and has a smaller inner circle.

This type of balance scales allows precise measurements to be achieved by ensuring that the balance's fulcrum is essentially friction-free by attaching a pointer to the beam which amplifies any deviation from a balance position; and finally by using the lever principle, which allows fractional masses to be applied by movement of a small mass along the measuring arm of the beam. The standardization of the weights used – and ensuring traders used the correct weights – was a considerable preoccupation of governments throughout this time and inspections were held regularly. When the Weights and Measures Act was passed in Victoria in 1862 local inspectors were established throughout the colony to ensure accuracy particularly in the weighing of gold. By the 1870's each local council had a set of standards that were used to test the scales, weights and measures of local merchants and businesses.Set of small scales possibly from a travelling boxed set due to their small size, similar to those used in an apothecary and weighing gold. Scales have two round brass pans with a cross bar and chains and pointer central on the lever arm. At top of lever arm above pointer is a small leather tag from which to hold up the scales. city of greater bendigo commerce, making a nation exhibition, city of greater bendigo mining

Cubed iron ship tanks were invented by Richard Trevithich in 1808, in partnership with Robert Dickson, and the design was patented that year. The invention eventually replaced the wooden casks or barrels used at the time, as the ship tanks were more secure and their shape was much more economical in storage space. The robust metal tanks were originally made to transport water, but their preserving quality enabled them to transport perishable dry goods such as grain on long voyages, as well as other forms of liquid and solid cargo. The first ship tanks were made from sheets of iron, and later mild steel sheets, with double riveted edges and corners. A round cast iron lid with handle grips was fitted snugly into the top opening, providing an air-tight and water-tight seal. Brass taps were often fitted into the base, which could have been the case with this tank, but it now has a wooden bung in the hole. Sailing ships began using the new ship tanks on Australian voyages from around the 1830s, storing food and water for those on board, and filling them with other cargo. A large number of the ship tanks were repurposed in 1838 for the Victoria Settlement at Port Essington, N.T., as they were able to protect the food, clothing and other stores from termite and insect damage. Other ‘recycled’ ship tanks were cut in half and used as washing tubs or cookers. A 1929 catalogue from Hudson’s Tank Stores advertised square tanks that contained around 600 litres – 160 gallons – which equals an internal measurement of 33.25 inches – 84.5 centimetres – per side ship tanks are still made and sold in 1952 by the Globe Tank and Foundry in Wolverhampton, England, which was incorporated in 1922. Today, ship tanks can be seen around Australia. Wilsonson’s Promontory Lightstation has the lid from a ship tank that was used on site for the storage of water. Some have been repurposed as domestic water tanks and dog kennels, others for eucalyptus distilleries. Flagstaff Hill has two ship tanks. The Campaspe Port at Echuca, once a bustling river port, has a ship tank beside the locomotive yard. The lids of ship tanks are collectible items. Richard Trevithick (1771-1833): - Trevithick was born in 1771 in Cornwall, England. He was a famous British engineer and inventor during the Industrial Revolution, known for his invention of the first full-scale working railway, the high-pressure steam locomotive, which he demonstrated hauling a railway train in 1804. He set up a small workshop in 1808 at 72 Fore Street, Limehouse, London, to make iron ship tanks, and this invention was instrumental in replacing the wooden casks formerly used for storage on ships. He was involved with mining technology, iron foundry and ship equipment. Ship tanks changed the way that cargo was transported on ships and other vehicles from the 1830s and were used into the mid-20th century. The ship tanks’ advantages were that they could store more content, lasted longer, were waterproof and airtight, stackable and could be repurposed for many uses other than water, such as fuel, dry goods and domestic cargo. They have even been used aa dog kennels and cookers. Ship tanks were part of the evolving methos to transport water, food and cargo, which changed in 1956 when Malcolm McLean invented the large, rectangular shipping containers that are in use today; they speed up the process of loading on and off the ships, saving time and money. Ship tank: a cubed iron container with an offset hole on one side. The hole has cutouts for securely attaching a lid. This tank is on its side on the ground with the opening facing sideways. The side facing upwards has a wooden bung in a round hole. The ship tank is made from six square, thick iron sheets, rolled and riveted along the edges. The inside has a black sticky coating, possibly bitumen, and a strong creosote odour. There are small remnants of green paint on the outer surface.flagstaff hill, flagstaff hill maritime museum and village, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, iron cube, water tank, shipping container, ship tank, ship's tank, ship tanks, marine container, richard trevithich, 1808, robert dickson, water transport, water storage, iron foundry, steel sheets, iron sheets, revets, victoria settlement, port essington, globe tank and foundry, wolverhampton, british engineer, british inventor, wooden casks

Feldspar, derived from the German word feldspat, is a group of minerals which is the most common mineral group found on Earth, making up more than half of the planet's crust. The major rock-forming minerals in the Feldspar group include albite, anorthite, orthoclase and microcline. (Mindat, Feldspar Group). Orthoclase is part of the Feldspar Group subgroup, Alkaline Feldspar, which are known to be poor in calcium, and mostly rich in potassium. It is further also considered to be a K Feldspar, a subgroup of Alkaline Feldspar that are Potassium-dominant with variable crystal symmetry and Al-Si ordering state. Orthoclase are most commonly Colorless to white, Greenish white, Grayish yellow, or Pale pink and transparent to translucent with slightly pearly cleavage. The mineral rates at a 6 on the Mohs Hardness Scale. (cannot be scratched with a knife, but scratches glass with difficulty). The stronger green colour of this particular specimen is distinctive to the Broken Hill region (where it was found), and due to a small amount of lead. (BB) Its qualities find it misidentified at times as as microcline variety amazonite. Broken Hill is one of the world’s richest lead-zinc-silver deposits. The huge, 300-million-tonne orebody was discovered in 1883 and the superb mineral specimens attract collectors from around the world. (Australian Museum, Minerals from Australia: Australian mining regions)While feldspar is not by any means rare, this particular specimen has qualities distinctive to the Broken Hill mining district, with these properties leading at times to the mineral's misidentification. This creates potential for further study and identification of these mineral deposits through methods such as microscopic twinning, or using the position of certain d values in XRD patterns to calculate the degree of disorder of a K-feldspar, as discussed on the Mindat website (Mindat.com, Orthoclase:About Orthoclase). 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.A solid small aluminosilicate mineral composition which is primarily pale green and blue-grey in colour with traces of beige and white throughout.

Horse team , Cocks Pioneer 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. Cock’s Pioneer Gold and Tin Mines NL carried on large-scale hydraulic sluicing operations until 1941. mining, gold, tin, sluicing, men, cocks pioneer, el dorado, eldorado, horses, gold mining, tin mining

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. Cock’s Pioneer Gold and Tin Mines NL carried on large-scale hydraulic sluicing operations until 1941. gold, tin, mining, sluicing, gold mining, tin mining, cocks pioneer, el dorado, eldorado
