The mine was located in the Howden Burn valley in the Bollihope Area of Weardale in the North Pennines, County Durham, England.

[2][1] One of the first publications about the Cornish Hush Mine described a fatal accident, in which miner John Collinson was buried underneath a large amount of rocks and lead ore falling onto him during his work and him killed immediately on 14 January 1863.

A colleague named Bainbridge had worked with him about two minutes earlier and then moved about 6 foot (1.5 m) away to smoke his pipe as the stones fell onto Collinson.

[4] On 27 July 1867, the Salmon Fishery Inspectors reported that they had visited several lead mines, where they inspected the hush, i.e. the waste water of the processing plant.

[2] The last agent of the Cornish Hush Mine was Joseph Anderson, and its last manager was Mr. Willis, before the London Lead Company went bankrupt in 1902.

[8][9] It had power of 2½ or 3 nhp and a loaded weight of 2.6 t.[10][11] Its footplate provided just enough space for the engineer, who could sit on the rear buffer beam, as known from its even smaller sister locomotives 'Ant' and 'Bee' of the Great Laxey Mine.
