From April to June 2014, personnel from Prewitt and Associates, Inc., conducted an archeological and historical resources survey for Camino Real Fuels, L.L.C., of the North American Coal Corporation and the Dos Republicas Coal Partnership (DRCP) within 1,460 acres of land at the Eagle Pass Mine in Maverick County, Texas. The archeological survey resulted in the discovery and documentation of 16 previously unrecorded sites. Of the 16 sites, 15 are prehistoric Native American sites, and 1 is an artifact scatter associated with a complex of ruinous buildings. Three of the Native American sites are within floodplain settings and contain subsurface deposits, while all other recorded sites are confined to the surface. The 3 floodplain sites, 41MV394–41MV396, are of unknown eligibility for listing in the National Register of historic Places under Criterion D and would need additional investigation for complete assessments. The other 13 sites are ineligible for National Register listing. The historical resources survey identified six resources: three buildings and a structure associated with the 1912–1944 Rohleder Brothers ranch; a mid-twentieth-century private irrigation system; and a ca. 1960 lake. These historical resources are recommended as ineligible for listing in the National Register
