Mineral exploration is a complex process involving rigorous field work to collect data and conceptualization to fit the data into a plausible theory. Mineral exploration proceeds step by step taking into account aerial photographs, satellite imagery, geological maps, geophysical maps, and geochemical maps to delineate areas of interest.
Gold production is the culmination of a complex process that begins with the discovery of economically viable gold deposits and ends with the extraction and processing of gold-bearing ore. Once a viable deposit is identified through exploration efforts, mining operations commence to extract the gold ore from the ground.
