Virginia Uranium - 2020

Uranium (Nuclear Minerals) / Exploration, Mining, Marketing, & Acquisitions

The Coles Hill Deposit, located in the Piedmont physiographic province of Virginia, consists of two approximately 350-meter-long by 250-meter-wide ellipsoidal mineral deposits (North CHD and South CHD). The character of the deposits is shaped by a complex combination of three major factors: faulting, fracture zones, and alteration. The deposits are hosted within a fault-bounded wedge of Paleozoic mylonitic quartzo-feldspathic gneiss and some amphibolite exposed in the footwall of the Chatham fault zone, which forms the northwest limit of the Danville Triassic Basin. The host rocks are Leatherwood granite gneiss and amphibolite, which display hydrothermal alteration by sodium metasomatism, chloritization, argillization, hematization and uranium mineralization.

The CHUP contains a fracture-hosted hydrothermal deposit, with uranium situated in mylonite. The deposit has characteristics of hydrothermal fracture type uranium deposits. Hydrothermal solutions and associated uranium mineralization are presently hypothesized to have been mobilized by tectonic events. The mechanism of uranium deposition at Coles Hill is similar to that in the Athabasca Basin, as indicated by the presence of alteration minerals hematite, epidote, and chlorite. A similar deposition mechanism in the Athabasca Basin has produced significant-grade uranium mineralization, which might also occur in the untested deeper parts of the Coles Hill Deposits (Jerden 2001).

The Coles Hill deposits are structurally controlled, with mineralization primarily concentrated in within the Leatherwood Granite. Mineralization is ten to several tens of feet thick, whereas along plunge to the south, the mineralization is continuous over tens to hundreds of feet (UMETCO, July 13, 1984). Both South Coles and North Coles strike northeast-southwest. South Coles plunges approximately 30 degrees to the southwest and the North Coles plunges about 20 degrees to the northeast. The general plunge of the mineralized bodies to the south is 40 degrees and the general plunge of the bodies to the north is 20 degrees. Uranium mineralization at Coles Hill is hosted by the Leatherwood Granite which is bounded by the Chatham fault to the west and to the east and at depth by the Fork Mountain Schist.
