1. Prospecting and Exploration ("Finding and Defining it") 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.
