A bogger is a heavy-duty piece of equipment used in underground mining to transport rocks, ore, and other materials from the digging face to processing facilities or loading areas. A bogger operator is an individual who controls the machinery used to transport materials.Colour photocopy of original photo.

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. All appear to be made out of brass All taper down to smaller base.gold mining, gold mining equipment, gold mining history

Electro hydraulic dredge Snake Valley 1909. J Mc Bennett, was an engineer back at the main base, at Dawson's dam on the Carngham Road, Between Linton and Snake Valley. These dredges were used for getting gold. The streams of water under high pressure just washed the hills and ground away. This dredge closed down early 1910. 200 H.P. motors were used and 10 in. pumps.Black and white image of three workmen, one beside mining building the other two at dredge pump outlet. Image mounted on dark brown card. Between 1904 and 1911 the Electro Hydraulic Company sought to extract gold in an area north of Linton known as the Hard Hills. By blasting water from high-pressure hoses into the hillsides, soil containing gold was washed out for sluicing. Two gravel pumps in Dawson's Dam pumped the wash through the sluices. Despite considerable investment in expensive equipment, the Company did not have a great deal of success, and the mining operation ceased in 1911.mining, gold, mining equipment, electro hydraulic dredge, dredging, sluicing, dawson's dam, snake valley, miners

A mining safety cage was used in a mine lift. It was fitted with mechanisms to prevent the cage from dropping if the lifting rope broke. In the 1870s in Victoria, deaths and injuries from falling cages in vertical shafts of gold mines were a major problem. The inventor of this safety cage was Robert Allan, a machinery maker of Creswick Rd, Ballarat. He said his cage featured a ‘dissolving’ fulcrum. Others called it an eccentric (off centre) system. Note the pair of clutch levers designed to grab the side guides if tension ceases in the suspending rope from the poppet head pulley. Also, the hinged ‘lids’; designed to protect miners trapped in a braked cage from falling rope, and to enable rescue of the miners. This model was presented to The Ballarat School of Mines Council in November 1876. This model was shown at the Smeaton Show in November 1874, Ballarat School of Mines Museum from 1876, and examined by the 1879 Victorian Board of Inquiry (Pg 15 of FedUni Catalogue 3437) From the Argus of 13 November 1874: At Smeaton Show, Robert Allan of Ballarat won 1st prize for a Model of a Mining Cage, a Butter working machine, a Cheese press and a Curd Mill. By 1878 an Allan Safety-Cage was in operation in the Number 6 shaft of the Band and Albion Consols mine in Ballarat. This cage was judged the best inspected by the Victorian Board of Inquiry by 1879, p. 39.Mining was a big industry in Ballarat in the late 1800s and a lot of deaths were recorded because of mining accidents, the development of the mining safety cage brake limited the deaths and injuries from falling cages in vertical shafts. The model also has links to the Ballarat School of Mines, being presented to the council in 1876. Ballarat School of Mines is the oldest Technical School in Australia and is a predecessor of Federation University. The model is significant to Ballarat's mining history.Model of a mine safety cafe. A grey painted wooden frame with metal model of cage and safety brake system. When tension ceases in rope a pair of crutch levers grab strongly onto the wooden guide strips which run down the sides of a vertical shaft. This safety cage was discussed in "Safety Mining Cages.

Gold bearing ore is pulverized by cast iron stampers (steam driven) and material then passes over a large copper plate covered in mercury causing the gold particles to combine with the mercury to form an amalgam which is scraped of and placed in a retort. The retort is heated causing the mercury to evaporate leaving the gold to be refined into ingots. The mercury is cooled as it leaves the retort and is reused. A second tray covered in what is called a blanket traps any fine gold that has passed the first plate. Finally the residue material goes over a vibrating table called a Wilfley Table which captures any iron pyrites which may contain about three percent gold. this is roasted and treated to recover any remaining gold at a special treatment plant.Wooden model of a five heads gold stamper battery. The gold stamper battery is a device for crushing ore. The parts of the battery are cams; dies; guides; kingposts; mortar box; shoes; stamps (or stampers); tappets. gold mining, mining equipment, gold stamper
