The relationship between surface landowners and mining concession holders in Chile is governed by law, which grants preferential rights to the latter. Mining concession holders may exercise their rights to search for minerals and impose mining easements on landowners. However, in the case of state property, such matters are regulated by a ministerial order.
Until 1979, the Mining Code 1932 defined the legal regime for lithium. During that period, lithium was treated like any other mineral and could be privately owned without special restrictions. This situation has changed with the enactment of a number of laws. Most recently, the Ministry of Mining's Supreme Decree 64 established special operation contract requirements and conditions for the exploration, exploitation and processing of lithium deposits in the Atacama region.
