From Introduction: "The Clifton Quadrangle, Arizona and New Mexico (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. An area of approximately 20,600 km2 was evaluated during this study."

From Introduction: "The Douglas Quadrangle, Arizona and New Mexico (Fig. 1) was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

From Introduction: "The Saint Johns Quadrangle, Arizona and New Mexico (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

From Introduction: "The purpose of the National Uranium Resource Evaluation (NURE) program is to identify and delineate areas and environments within the Gallup 1º x 2º Quadrangle, Ariz. and New Mex., that exhibit characteristics favorable for the occurrence of uranium deposits that have the potential to contain at least 100 metric tons U3O8 total endowment with an average minimum grade of 100 ppm (0.01 percent)."

From Introduction: "The purpose of the National Uranium Resource Evaluation (NURE) program of the U.S. Department of Energy (DOE) is to identify and delineate areas and environments with the Shiprock 1ºx2º Quadrangle, New Mex., Ariz., Colo., and Utah, that exhibit characteristics favorable for the occurrence of uranium deposits that have potential to contain at least 100 metric tons U3O8 total endowment with an average minimum grade of 100 ppm (0.01 percent)."

From Introduction: "The Silver City Quadrangle, New Mexico and Arizona (Fig. 1), was evaluated to identify geologic environments and delineate areas that could containg uranium deposits aggregating at least 100 tons U3O8 at an average grade not less than 100 ppm U3O8."
