Gold Mining Mining Shares | Guide from BullionVault
Gold is rarer even than platinum, although because of platinum's more even dispersion in the Earth's crust it is actually harder to find commercial deposits of platinum. Gold is more frequently deposited in the concentrations which make gold mining viable. Gold's average concentration in the Earth's crust is parts per million....

» The Basics of Successful Gold MiningPart 1
Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the "paystreak". Paystreaks always form along the gold path where the river's flow slows down on a large scale during a major flood storm....
