However, while addressing those issues, it must also establish an acceptable post-mining land use and ensure that work areas are safe. At the Sepon site, which was heavily bombed during the second Indochina war, the selection of a post-mining land use is not as simple as the often stipulated condition ‘to return the land to its pre-mining use’. Furthermore the presence of considerable quantities of unexploded ordinance (UXO) makes the task of site rehabilitation more challenging. However, this also creates some unusual opportunities.
