The gold prices used in this table and chart are supplied by BullionDesk. Where the gold price is presented in currencies other than the US dollar, it is converted into the local currency unit using the foreign exchange rate at the time (or as close to as possible).
• Explorationgrade analysis – This class of analysis is intended for large scale reconnaissance exploration programs. Typically, such programs generate rock or soil samples with low metal contents. In general, the frequency of inserted quality control materials is a minimum of 11% and methods with upper measurement limits of about 1% are used.
Gold pans: Most people immediately think of the gold pan as the most important tool for gold prospecting. However, a brain is required to operate it, select the right location on the stream, get permission to enter the land and decide that the land has potential.

Gravity, Electrical, Magnetic and Seismic Methods . Gravity Methods. The gravity field of the Earth can be measured by timing the free fall of an object in a vacuum, by measuring the period of a pendulum, or in various other ways. Today almost all gravity surveying is done with gravimeters.
Exploration and development— geophysical methods used in search of minerals, groundwater and geothermal resources A layman''s summary. Geophysical techniques are routinely used in exploration programs to help delineate and map areas favorable for the target being pursued, determine or rule out drill locations, and maximize extraction over the lifetime of a mining or development project.
