Basic Gold Prospecting & Exploration Methods

The samples can be assayed for several elements if there is not any economical restriction, otherwise the assays must include at least gold and silver. In this way we can know a preliminary distribution of metals. For example, of 100 samples collected the average gold value can be 2 g/t, with 40 samples reporting more than 1 g/t gold.
