Transcript of GOLD!!!!!
Australia The Australian Gold Rush of the 19th century had big impact on Australia. There is no doubt that the gold rushes had a huge effect on the Australian economy as well as our development as a nation. The discovery of gold led to many men and women leaving their homes and jobs and depart to the gold fields. However, life on the goldfields proved to be harsh, as the diggers faced challenging conditions. Many left either without anything or even poorer than they started. Beginning of the Gold Rush Life on the goldfields Gold and it's Properties Gold is a dense, soft, shiny, malleable and ductile metal (easy to work with). It is a chemical element with the symbol Au and atomic number 79.There are 24 carats in pure gold. However pure gold is really soft so people mix gold with other metals to make the gold stronger. This is called alloying. Gold has a bright yellow color and shining brightness. This is traditionally considered attractive, which it maintains without oxidizing in air or water. Gold is rare and is one of the only metals that doesn't rust, thus people adore it and want it. Also it is highly conductive which is good for electronics. One of the major causes of death on the goldfields was sickness' and diseases such as Typoid and Cholera. This is due to the fact that there was a lack of fresh water. So everyone bathed and drank from a dirty water source. Diggers didn’t shower or bathe very often especially in summer because the water was very dirty and in short use. Also there was little medical help on the goldfields so the health of the diggers wasn’t very good. Another cause of death on the goldfields was the unpredictable conditions. Many people died in mine shafts looking for gold as a result of the mineshafts giving way or underwater floods. The main commercial centre for supplies and information in NSW was Bathurst. This because of the fact that mostly people came to Bathurst to find gold. Also Bathurst was very far from local towns. So the people decided to make Bathurst the main commercial centre of the NSW goldrush. The Australian Gold Rush started in 1851, when Edward Hargraves, a prospector from Gosport, England searched areas in NSW for gold. As a result his assistants, John Lister and James Tom found grains of gold at Summer Hills Creek, a waterhole about 40km from Bathurst. Yet Edward took credit for finding it. People from all over the world heard about the discovery of gold in Australia. In 1852 alone, 370,000 immigrants arrived in Australia and the economy of the nation boomed. This saw the population of Australia triple from 440,000 people to 1,700,500. Many immigrants came from Europe, Asia and America. However most miners were from China. The Holtermann Nugget is named after Bernhardt Holtermann who found it at Hawkins Hill, Hill End New South Wales. It is the largest gold specimen ever found weighing 286 kg (630 pounds), and is 1.5 meters (59 inches) long.

He actually pasted The photo of the the Holtermann Nugget next to a photo of himself photo. One of the most famous towns of the Gold Rush Era was Ballarat. This is beacuse there was a lot of Alluvial Gold on the Ballarat goldfields, so people flocked to find gold and Ballarat's population grew. By 1853, there was more than 20,000 miners of many nationalities working on the Ballarat goldfields. This historic town was the scene of one of Australia's most famous riot, The Eureka Stockade. People on the goldfields mostly traveled by foot. All the poor families could only get to places by foot because they couldn’t afford horses because they were very expensive. The rich families that found gold traveled by horses and carriages. Some people came to the goldfields by donkeys or bullocks because they can carry large amounts of weight. People from other countries came to the goldfields by ship because there was no other way to get over seas. Ballarat Fool's gold, also known as iron pyrites, is a brass or gold-colored mineral that is easily mistaken for real gold. The early miners during the gold rush often thought they had made a fortune, only to discover their finds were not real gold. Fool's Gold is called fool's gold due to its color and uneven texture. While real gold holds monetary value, fool's gold is virtually worthless. You can tell the difference between fools gold and real gold as real gold ranges from a golden color to a silvery yellow hue. The yellow of pyrite, on the other hand, is more brassy whether it is a pale or deeper yellow. Gold is a soft metal and lacks the hardness of pyrite. Because gold is soft, it will flatten out or alter its shape when you hit it with a hammer, but it will not break. Pyrite is much harder and your hammer will likely strike sparks from the mineral when you do this test, because of its high iron content. In modern days we use gold for various things. These include: Monetary Exchange, Jewellery, Medicine, Electronics, Food, Dentistry, Shielding against Light and Heat, in Space, Art, Medals, Gold plating and much more. A person who searches for gold is called a prospector, miner, panner or a digger. Prospecting is the first stage of the territory geological analysis physical search for minerals, fossils, precious metals or mineral specimens, and is also known as fossicking.
