[en] This paper reports on the Jackpile-Paguate uranium mine in west-central New Mexico, the largest surface/underground uranium mining complex in the United States. The mine, which has been defunct since 1982, is on tribal land belonging to the Laguna Pueblo. Very little reclamation had been performed when the operator left the site. A financial settlement was eventually agreed upon between the Laguna Pueblo and the former operators of the mine. The authors prepared a reclamation plant that optimized expenditures of the reclamation fund. Computer codes were used to determine minimum cover thicknesses for adequate radon control and to develop the most cost-effective earthwork program. Favorable overburden strata were selected for use as topdressing. The Laguna Pueblo now has a completed reclamation plan and implementation is underway
