search for economically exploitable mineral deposits. Until the 20th century prospecting involved roaming likely areas on foot looking for direct indications of ore mineralization in outcrops, sediments, and soils. Colours have been a traditional guide to ores. The reds, browns, and yellows of limonitic material, for example, can indicate leaching of sulfide-bearing veins and disseminated ore bodies. On weathered outcrops, greens and blues could indicate oxidized copper minerals, black could mean oxidized manganese minerals, and yellows and greens the presence of silver halides.
