In return for the investment, Adventus Mining and Salazar are negotiating government guarantees on security of title and investment, reduced tax burdens on both income taxes and the capital outflow taxes, guarantees on infrastructure development, among other items, which are customary features in similar agreements the government has established on other major Ecuadorian mining projects.
