Abstract

The case study presented here reviews the uranium resource estimates and summarizes the property situation of the Coles Hill uranium Deposit. Uranium resources at Coles Hill are then classified according to UNFC-2009.

The Coles Hill Deposit is located in Pittsylvania County, southern Virginia, United States (Figure 14). Coles Hill was discovered by the Marline Corporation who identified an outcropping surface radiometric anomaly in 1979. The deposit was delineated by Marline and UMETCO (a subsidiary of the Union Carbide Corporation) from 1979 to 1984. In all, 182 rotary holes (38,037 metres (124,799 feet) of drilling) and 74 core holes (19,836 m (65,082 feet) of drilling) were completed and two distinct deposits, the North and South Coles Hill Deposits were defined [66]. Marline let its option to develop the property lapse in response to low uranium prices and a moratorium on uranium mining in Virginia that was passed in 1982. In 2006, a corporation formed by the majority property owner, Virginia Uranium LLC, consolidated 2,296 acres (929 hectares (ha)) in surface rights and 2,940 acres (1,190 ha) in mineral rights, which cover most of the north and south deposits. In 2008, Virginia Uranium drilled 3 core holes and 7 rotary holes. Geophysical surveys were completed for 5 historic holes to confirm earlier results. The Marline core was donated to, and is curated by, the Virginia Natural History Museum; the Marline core is stored on site along with the core drilled in 2008 by Virginia Uranium. The property is accessible from secondary paved roads and the infrastructure, including access to power and water and proximity to local support services, is excellent.
