Prospecting and exploration are precursors to mining and often occur simultaneously; together, they can take two to eight years to complete, and may cost from $500,000 to $15 million overall. Prospecting is the process of searching the region for mineral deposits. Historically, prospectors would explore a region on foot with a pick and shovel.

According to miners in southern Peru, mined copper is mainly sold raw as it is more profitable for small-scale and artisanal miners, given that a quantity of at least 100 tons is required to make it into concentrate, apart from paying rent for the use of the plant. For this reason, miners prefer to sell it raw to the actual concentrator plants.
