Feb 01, 2017 (A Wilson) - The property is situated on the northwest margin of the Cheddar granite batholith. To the west it is underlain by metasediments and paragneiss striking NNE and dipping 60-80ºE containing lenticular bands of granitic pegmatite.

Feb 01, 2017 (A Wilson) - Radioactivity in pegmatitic granite within the border phase of the Cheddar Granite is erratic and discontinuous. Strong radioactivity is usually associated with hematization and smoky quarts, and in the North group, with traces of fluorite. In the North group, a pegmatite reading up to 70 times background is exposed. In the south, several anomalous zones up to 1600 feet long have been established. Rock trenching and chip sampling on the north and south groups returned assays of 0.22 pounds U3O8 per ton over widths of 13 and 34 feet respectively.
