They are deposits of minerals, fossils, gems and water existing in the interior or outcropping on the surface of the earth and have economic value.
The best known deposits are gold, iron, oil, limestone and mineral water, but there are several other types of materials that form the deposits.
The deposits valuation considers several factors, such as: geology, reserve (measured, indicated, inferred), legal authorization for the mining, environment, production capacity, useful life of exploration, production process, among others.
The economic value of the deposit depends on gross and net revenues, cost production, operating expenses, taxes, profit and other relevant economic and financial data. Operation risks are analyzed in detail to define the present value of cash flows.
The result of these calculations defines the economic value or market value of the deposits.
