Tolgarrick Mine, St Stephen, St Stephen-in-Brannel, St Austell District, Cornwall, England, UK
A trial made in 1922 in search of an extension of the South Terras uranium lode. The workings included an adit that was driven eastwards from the valley of the river Fal and a shaft to which it connected at 75 fms from its entrance. Where the lode was expected, short levels were driven to the north and south, but they only encountered strings of barren quartz. The adit was continued beyond the shaft and intersected with an elvan, from where radiocative water entered the workings. Without hitting a lode, it was abandoned at 133 fms from its entrance.
UK Grid Reference: SW934519
The workings are now completely obscured. The grid reference marks the approximate position of the adit portal.
