The Maddingley area of Bacchus Marsh was surveyed for brown coal deposits in the 1930s. By the early 1940s brown coal in large quantities was being extracted and was transported to Melbourne where it was used to fire boilers for the Australian Paper Mills (APM) company. By the 1970s APM was using natural gas instead of coal. Maddingley brown coal was then used to fire boilers for the CRA/VISY cardboard factory at Bacchus Marsh. This factory closed down in 1990. During the 1990s the mine was acquired by the Calleja family company who ran transport and waste management operations.The Maddingley Brown coal mine was a major industry in Bacchus Marsh for 50 years. A sample of coal from the mine is a reminder of the importance of this local industry over an extended period of time.Two cylindrical plastic containers mounted on rectangular baseSample of pulverised brown coal produced from Maddingley brown coal deposit located at Bacchus Marsh Victoria, October 1981.

The permanent fruit fly road blocks in Victoria began in 1958. The first was set up on the Lincoln Causeway between Albury and Wodonga. The aim was to protect the Victorian fruit export industry, the largest in the country. Cars would be stopped and inspected when entering Victoria. At peaks periods, such as Easter and school holidays, there were up to 10 inspectors at the 24 hour checkpoint near the former butter factory on the Lincoln Causeway. Local residents could apply for a pass such as this one which would be displayed on their window, but were still subject to random checks. Hundreds of tonnes of fruit each week was confiscated and pulverised by Department of Agriculture staff. The road block was closed in 1980, partly due to the increased traffic flows and the cost of maintaining inspection points.This image reflects government measures taken to protect the fruit industry in Victoria.A transparent sticker designed to be applied to a car window for motorists to pass through Department of Agriculture fruit fly control points.

This particular specimen was recovered from the Lal Lal Coal and Iron Mine in Victoria, 19km from Ballarat. Brown Coal was discovered here in 1857, just alongside the Geelong to Ballarat Railway line. This discovery of lignite (brown coal) was the first in Victoria, which would bring important benefits to the region and state, both of which had previously been reliant on coal imports. In the 1860s, iron ore was found just 5km from Lal Lal, and the area was converted into an Iron Ore Mine. The Lal Lal Iron Mining Company took over operations in 1874, who then peaked iron production in 1884. This mine continued operations until June 1884, when the blast furnace was extinguished and never recommenced. The blast furnace at Lal Lal is considered one of the most important and highly significant sites ion early industrial history in Australia, as it is the only remaining best furnace from the nineteenth century in the Southern Hemisphere. The furnace ruins are 17 metres high, and are clearly visible today on Iron Mine Road, Lal Lal, near the Bungal Dam. This specimen of Lignite (brown coal) is significant, as it was mined from the area where brown coal was first discovered in Victoria, leading to an important and controversial future of the mining and use of brown coal in this State. The Victorian Heritage Database has listed the Lal Lal Coal Mine with local significance, with their Statement of Significance stating: "The Lal Lal coal mine is historically significant as the site of the first discovery of lignite (brown coal) in Victoria, and one that promised important benefits to regional and state industries that were reliant on coal imports at the time. The significance of the stie is reduced by the poor state of preservation of the coal mining and processing fabric". 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 hand-sized light-weight, soft and combustable sedimentary rock specimen, that is dark brown in colour. The specimen has jagged edges, as though parts of the rock have crumbled away. Brown coal, or Lignite, is formed naturally from compressed peat, and is typically found in natural basins. The stages to the formation of coal ('coalification') begin with plant material and wood, which will decay if it is not subjected to deep burial or heating, and turn into Peat. Peat, when sufficiently compressed naturally, will turn into Brown Coal (Lignite), and finally into Black Coal (sub-bituminous, bituminous and anthracite). Each successive stage has a higher energy content and lower water content. It is brownish-black in colour. Brown Coal has a high moisture content, between 50 and 75 percent, and a low carbon content. Some Brown Coals may be stratified, with layers of plant matter, which means little coalification has occurred beyond the peat natural processing stage. When Brown Coal is submerged in dilute nitric acid or boiling potassium hydroxide solution, it reacts to produce a reddish solution, of which higher-ranked coals do not. When brown coal is pulverised and burned in boilers, the steam is used to drive turbines, which generates electricity. It is the lowest rank of coal, as when burned, it creates a relatively low heat content, which in turn does not create a great output of steam. burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, mineralogy, brown coal, brown coal specimen, lignite, lal lal, lal lal coal mine, lal lal iron mine, ballarat, blast furnace

The Gem The Poseidon Rush. Tarnagulla, Saturday. Article - The Albury Banner and Wodonga Express (NSW : 1871 - 1938)Friday 8 February 1907 - Page 43 The Poseidon Rush. Tarnagulla, Saturday. Several indicators and quartz leaders on the Woolshed Hill have received considerable attention during the last fortnight. In some claims the stone looks very promising, and nice tracings of gold have been obtained. Wragg Brothers struck it rich yesterday. At a depth of 12ft. on the bedrock they discovered a nugget specimen 206oz. in weight, which has been christened the 'Port Arthur. The party also had the good fortune to find two other specimens close, by, one weighing 23oz. 15dwt. and the other 24oz.These were named 'The Twins,' the Wragg Brothers bearing that distinction. In this claim about eight weeks ago the Gem (88oz.) was unearthed. THE POSEIDON RUSH. Article Illustrated - Leader (Melbourne, Vic. : 1862 - 1918, 1935)Saturday 29 December 1906 - Page 33 THE POSEIDON RUSH. It is only about five weeks since this rush was opened by John Porter, but since that time a marvellous change has taken place. The quietness of the bush has given place to a scene of wild excitement, and each week this is intensified by the discovery of large nuggets. When Smith, Rogers and Stephenson picked out their slug on election day, no one dreamed that larger ones were lying only a few feet away, but such was the fact. On Tuesday afternoon two immense slugs, one of which weighed 960 oz., and the other 373 oz., were found in adjoining claims within a few minutes of each other. The finding of these created a scene which it is difficult to describe. "I've got one, “was shouted from the claim of Bert Williamson and T. Stephenson, two men just entering into manhood. They were seen excitedly digging round a lump of gold, one of them with a double-ended pick, the point-of which he broke in his anxiety to unearth it. This slug is nine inches long by seven inches by 43 inches, and is very similar in appearance and size to the big nugget got previously in the adjoining claim. It has been cleaned and smelted, and has yielded 306 oz. of pure gold of the best sample. Before the excitement caused by the discovery of the last nugget had sub-sided, there was a shout from an adjoining claim. Sam Woodall, a Llanelly miner, felt his pick strike a hard yielding sub-stance, and, satisfied that he had struck a nugget, called the attention of his mates to the fact. He soon levered it out of the ground with his pick. Taking it up in his arms he staggered out of the claim with it, and in a minute or two was sur-rounded by hundreds of men who rushed from all over the field to view it, and to feel its weight. It was certainly a magnificent specimen, and the fortunate miners were congratulated on all sides. Its weight was guessed to be a hundredweight, and probably in its then dirty state it would nave turned the scales at that. In a few minutes the crowd was so dense that it was impossible to get a close inspection. The nugget was first taken to Newbridge under escort, then through Llanelly to Tarnagulla, where it was lodged in the Union Bank. It was found that the bank scales were not sufficiently large to weigh the mass. By tying a number of large weights together, and suspending them from a steel bar, a fairly accurate weight was obtained, and it just balanced 80 lb., or 960 oz. The nugget measures 16 in. x 10 in. x 5 in. The party was cheered as it drove up the main street here, and the sight of an armed escort was quite a novelty. The nugget was held aloft in a tin dish for inspection by the crowd. These nuggets were found in the shallow workings, and neither of them were a foot under the surface. The ground is a black loamy soil; there was no appearance of wash whatever, and no one knowing anything of alluvial mining would think of searching for gold in such a spot. All those who have claims on the hillside are breaking out all the dirt in a face from the surface to the reef, which is a mixture of lime and sunstone, and searching for nuggets. The ground is carefully pulverised so that nothing shall be missed. Some are puddling the whole of it, but it is hardly payable. Where the big nuggets are now being found, the ground has been pegged out and abandoned more than once since the rush started, and shares in the claims have been purchased for small amounts. Smith was given a third share in the claim where the first nugget was found for puddling the dirt big lump was discovered, by Woodall, Condron, Brooks and Eva, two of them sold a sixth share for £5 a few days ago to a man named Woods, who only worked a few days and sold out again for 50/. Some fancy prices are now being offered for shares in the claims in the vicinity. Woodall holds a third share, Condron and Brooks three-quarters of a share each, and Eva a sixth share. The largest nugget has been christened "The Poseidon." The names given to the other nuggets obtained previously are as follow: — Wragg Bros., 88 oz. nugget, "The Gem"; Smith and party's 378 oz. nugget, which was unearthed on election day, has been fittingly named "The Federal"; Jackson and Hughes 152 oz.specimen, "The Little. Beu"; Williamson and Stephenson's 373 oz. nugget is said to be called "The Christmas Box."

Cast iron mercury bucket, used to hold mercury, potentially in the process of recovering minute pieces of gold mixed in soil and sediments. See research page for description of one process of using mercury to extract gold.gold mines, mining equipment, mercury bucket, miners used mercury in a number of ways to amalgamate gold, with each mill or battery operator having their preferred method depending on the nature of the ore. by the late 1850s the most common way of crushing goldbearing quartz ores or consolidated alluvial cements was in a stamp battery. the battery featured heavy iron stamp heads held in a frame, with each head often weighing up to 500 pounds (226 kg) or more (see msv 1880, page 45) (birrell 2005). stamp heads were lifted and dropped by a rotating overhead cam shaft driven by a steam engine or water wheel. ore was fed into a large cast-iron battery box, mixed with a steady stream of water, and pulverised by the stamp heads. in some batteries, mercury was placed in the base of the boxes to amalgamate with freed gold. the violent agitation of the mercury in the mortar box, however, could cause the mercury to break into myriad tiny globules that were carried away by the water with the tailings, thus losing a certain amount of gold in the process (thompson 1867; ritchie & hooker 1997). the water and sand slurry was splashed by the falling stamps from the box through fine mesh screens and onto inclined wooden tables below the mortar box (figure 2). the tables were covered with copper sheets or plates coated with mercury, which caught and amalgamated with a portion of the gold. the grey putty-like amalgam was periodically scraped off the sheets and retorted in a furnace to collect the gold and recover the mercury for reuse. mercury was inevitably lost from the plates, while poor maintenance resulted in further losses of gold and mercury in the tailings. mercury use and loss from gold mining in 19th century victoria. peter davies1, susan lawrence, and jodi turnbull, department of archaeology and history, la trobe university.

Blue handwritten one page document detailing 'Youngman & Harrisons Patent Basin for pulverizing quartz tailings and amalgamating fine gold with mercury'. Introductory comments the basin contains greater advantages for pulverizing quartz tailings & amalgamating than any yet constructed for that purpose; In its construction all machinery complications have been carefully avoided and yet it embodies all the best methods known for treating tailings and has besides other than advantages (both in cash and labour) that of treating puddling machine sludge and can be used as a concentrator with little or no extra expense.bendigo, mining, youngman & harrisons patent basin
