Abstract
A geologic, geophysical, and geochemical investigation and a survey of mines, quarries, and prospects have been conducted to evaluate the mineral resource potential of the Lost Cove and Harper Creek Roadless Areas, Avery and Caldwell Counties, North Carolina. The study area lies within the Blue Ridge physiographic province and is predominatly underlain by Precambrian age plutonic and metasedimentary rocks of low metamorphic grade. All surface and mineral rights are Federally owned. Permit areas for uranium prospecting cover about 85 percent of the area.
Uranium-rich rock in the Lost Cove and Harper Creek Roadless Areas occurs widely in the Wilson Creek Gneiss and to a minor extent in the Grandfather Mountain Formation. Vein-type deposits and other occurrences of uranium in foliated rocks in the Wilson Creek Gneiss have uranium resource potential. Speculative resources of uranium in vein-type deposits and in supergene-enriched foliated rocks are estimated to total 4 to 8 million pounds of U3O8.
Mineral resources having low to moderate potential are gold and minerals of thorium, beryllium, niobium, and copper. Stone has a low economic potential; lead, molybdenum, and titanium have low resource potential. These conclusions are based on results of prospect examination, radiometric survey, geochemical survey of stream sediments, saprolite, and bedrock.
