Heart of Gold Lesson Plan Year 7

Depending on where the gold is found, this may be done by panning or through dry blowing. Each of these methods relies on the property of density. As gold has a very high density compared to the rock, soil and sediments it is contained in, it can be separated out by exploiting this property as it will fall to the bottom of mixtures that are allowed to settle out. The process of panning is used when small pieces of gold are found in creeks and rivers. It involves using a large shallow dish (pan) to scoop out some of the sediments in the riverbed and a small amount of water. You use a swirling motion with the pan tipped away from you and allow small amounts of the sediments and water to spill over the edge of the pan. When you have only a small amount of the sediments remaining in the pan, you will be able to see any gold particles that remain at the bottom of the pan. During the West Australian gold rush, most of the gold was being found in dry areas and water was a scarce commodity. -

The Albert Goldfield, Milparinka-Tibooburra, North-Western NSW
Journal of Australasian Mining History, Vol. 5, September 2007 A Thirsty and Confusing Diggings: The Albert Goldfield, Milparinka-Tibooburra, north-western NSW By KEN MCQUEEN University of Canberra succession of scattered discoveries from 1880-1882, over a tract 50 miles long by 10 miles wide in the Grey Ranges of far north-western New South A Wales (Figure 1) saw the establishment of the Albert Goldfield. These alluvial diggings were amongst the last discovered in New South Wales and the first in the arid outback. They provided ‘poor man’s’ diggings where individual prospectors or small parties could recover payable gold without heavy capital outlays, by ‘raking’ the shallow gullies overlying the bedrock of the isolated ranges. At first the prospectors were confused by the occurrence of gold in widely scattered near-surface patches with no clearly defined leads or deep leads. Some good deep leads were eventually found and worked, but were then abandoned due to flooding water. Gold-bearing quartz reefs were also found, but the cost of fully developing these in this remote region proved too much for the small companies involved. Prospectors faced enormous difficulties in the hot, dry terrain (summer temperatures commonly over 100º F and average annual rainfall of 6.5 inches); the most serious being shortage of water for both mining and domestic purposes. However, periodic downpours and flash flooding also adversely affected mining operations. During the numerous dry periods the miners had to stack their washdirt and simply wait for rain, or resort to the tedious and inefficient process of dry blowing. -
