A small copper mine, working a NE-trending lode known as Martin's Lode which dropped into the hangingwall of Highburrow Lode of Tincroft Mine below the 120 fm level. It was developed from Roger's Shaft (called Fanny's Shaft on the Ordnance Survey map) and Fanny's Shaft (called Western Shaft on the Ordnance Survey map) which were located at a distance of about 80 yards just south of the railway line. The area is now largely obscured by building operations.
The sett was bounded to the east by Carn Brea Mine, and to the north by Tincroft Mine, with which the workings were connected underground. In 1819, Wheal Fanny broke the main beam of her pumping engine and the subsequent flooding rose to a few fathoms of the communication between the mines before the engine was repaired.
From 1815 to 1822, Wheal Fanny raised 8,450 tons of 9% copper ore. In 1831, after some period of inactivity, it was incorporated into Carn Brea Mine.
