Any person who is giving up or quitting in their personal life hasn't much chance of succeeding at gold mining! If you are not finding enough gold, you cannot blame the claim, the river, the club you belong to, or anything else.
Searchlight Minerals Corporation Announces Operations Update For The Process System To Extract Gold And Iron From Its Clarkdale Slag Project
Some early miners also used an early form of hardrock mining, digging solid veins of gold out of rock, where mineralized water had deposited it over thousands of years. Today, gold is extracted in hardrock mines that directly mine the source rock, or "lode" of gold, where it was originally deposited by geochemical processes.

Placer Mining. The first tools used to mine gold were extremely simple, knives, small wooden hand tools, such as picks and shovels. Extraction of gold from ore bearing gravel without water was termed dry washing. It was a crude and inefficient, but also inexpensive.
Gold is also extremely heavy, with a density of g cm3. The density of lead, by comparison, is only g cm3. Its heaviness plays a crucial part in many of the physical methods used to extract gold from its various sources. Gold is the most malleable (something is malleable when it is easily beaten into a thin film) element there is.

Gold Extraction Methods Alluvial gold is extracted using a rocker and cradle or simple sluice and various panning techniques. Reef gold is imbedded in quartz rock, which has to be crushed to release the gold caught in the seams.
SELECTION OF METHODS FOR SEPARATING OF GOLD. Composition of natural gold includes the following admixtures: silver, copper, lead, bismuth, antimony, iron, tellurium, and arsenic. Impurity complicates the selection process of method for gold separation and development of .
Mine operators extract minerals from underground mines, surface mines and quarries using machinery and explosives. Some extraction processes, such as stone quarries, may use large quantities of water. After extraction, many types of raw minerals are then subject to processes such as crushing, milling, washing and chemical treatments.
But if we were to run out of a mineral — as in, exhaust our supply — it probably wouldn't be because there's none of it left on Earth. The problem would be that the processes used to extract it have become too expensive, difficult or harmful to make mining worthwhile.
