The Lone Star deposit is located in La Bajada Canyon in western Santa Fe County, New Mexico. The exposed sedimentary rocks of the area range in age from the Cretaceous to recent. Four unconformities are present which are the result of erosional levels established during the Tertiary. The host rock of the deposit is the Cieneguilla liburgite formation. The Cieneguilla consists mainly of thin embedded limburgite flows and conglomerate of Miocene age. The Lone Star deposit lies in this conglomerate at a depth of approximately 150 feet from the top of the Cieneguilla
