At the other end of the spectrum ghost towns, such as Walhalla, Mafeking and Steiglitz still exist.

As with many gold towns, after deposits of gold had been exploited, the town of Cassilis ceased to exist. This picture shows the remains of part of King Cassilis Mine

The last major gold rush in Victoria was at Berringa, south of Ballarat, in the first decade of the 20th century. Gold mining ceased in Victoria, not because there was no more gold but in part because of the depth and cost of pumping. The First World War also drained Australia of the labour needed to work the mines, but worse the prohibition on the export of gold from Australia in 1915, the abolition of the gold standard throughout the Empire, saw many goldtowns in Victoria die. The slump in gold production never recovered. However, as of 2005 the recent increase in the gold price has seen a resurgence in commercial mining activity; mining has yet to be resumed in Bendigo, while some is occurring in Ballarat, and exploration proceeds elsewhere, for example, in Glen Wills, an isolated mountain area near Mitta Mitta in north-eastern Victoria.

Aprender acerca del lavado del oro haciendo una de las siguientes actividades:


6a

Hacer lavado de oro (preferido)


Most states in the U.S. have areas where gold can be located. The best way to meet this requirement is to go to an area and actually dig up the material and pan it there. It would be best for the instructor to scout the area first and find a location where there is at least some gold available, ideally there should be at least a few flakes or specs of gold in each pan.

Another way to meet this requirement is for the instructor to get some gold bearing material and then have the students pan it in some type of trough, the plastic pans available at your local hardware store for mixing mortar work well. You can also build a panning trough out of 2x10 lumber with a thin plywood bottom and line it with plastic.

You can also purchase black sand concentrates from various locations on the Internet. These can be mixed with sand and gravel from a local river or stream bank and then used for panning. When panning don’t fill the pan completely full. It is easier, especially for beginners to start with a pan that is 1/2 to 3/4 full. You may also want to drop a small lead weight like a fishing weight into the pan. If the lead is still in the pan when the pan is down to just black sands then you can be sure that the gold is still there also.


6b

Practicar la batea de oro usando plomo aplanado o tungsteno mezclado con arena (preferible de un banco de arena de un río)


Get some sand and gravel, from a river or stream bank if possible, and mix in a specific number of flattened lead or tungsten shot. Tungsten shot would be the best choice for two reasons if you can find it. First unlike lead, tungsten is non toxic, and second, while lead at 11.3 is only about half the specific gravity of gold, tungsten is almost identical at 19.62.

Encontrar los siguientes versículos de la Biblia y discutirlos en relación con la búsqueda de oro.



7a

Mateo 13:44-46



44The kingdom of heaven is like treasure hidden in a field, which someone found and hid; then in his joy he goes and sells all that he has and buys that field. 45Again, the kingdom of heaven is like a merchant in search of fine pearls; 46on finding one pearl of great value, he went and sold all that he had and bought it.
-- Matthew 13:44-46

This verse suggests that it is perfectly acceptable to prospect for high value items. God wants us to be financially successful. The kingdom of heaven, like high value treasure, is worth having.


7b

Mateo 6:19-21



19Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal. 20But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal. 21For where your treasure is, there will your heart be also.
-- Matthew 6:19-21

Here Jesus covers the flip side of earthly treasure. Putting earthly wealth ahead of heaven is disaster. As in most things, Christians need to seek a reasonable balance on earth and put the emphasis on heavenly things.
