Appears to be a generic location. There were a number of lead-zinc mines within about a 5 mile radius of the town of Holywell, including Trelogan to the west, and the mines of the Halkyn mining field to the south.

OS national grid reference is for the town of Holywell itself and is not a specific mineral location.
