Operational from 1860 to 1870, and later re-worked in 1912, this mine primarily extracted silver and uranium, although there are no available records detailing its output. The main adit, which was explored by the Atomic Energy Authority in the late 1950s, can be accessed at the base of a quarry, situated to the left of the footpath leading from the disused mill to the old railway. The mine is located northeast of Ponsanooth. It’s worth noting that the name ‘Wheal Gal’ is inaccurate, as referenced in Hill et al. (1906). The name likely originates from Pryce (1778), who mentioned a mine yielding cobalt ores, but this reference is believed to actually pertain to Roskrow United Mine, a mine for tin and gossan (gal) near Ponsanooth in Perranarworthal.

Dines:

A mine, also called South Tresavean, situated on the north side ofthe stream that passes Ponsanooth and Perran Wharf (6-in. Corn. 64 S.W.) . Several E.-W. lodes are indicated by crop workings in the wooded ground between the railway and the stream, where the country rock is metamorphosed killas within 200 yds. of the granite margin. The plan (A.M. R 29, dated 1860) shows workings on one of these (underlying 28° N.) consisting of a crosscut adit commencing near the stream 200 yds. E. of Victory inn, Ponsanooth and intersecting the lode at 20 fms . N.E. of the entrance. Adit Level extends there from 8 fms. W and to 18 fms. E. where it meets Old Engine Shaft (on the underlay to the 10-fm. Level). The 10-fm. Level is driven 45 fms. W. from that shaft and at 20 fms. W. connects with Engine Shaft, vertical to the 10-fm. Level and on the underlie to the 30-fm. […]
