Operated by the Brendon Hills Iron Ore Company, the mine had been worked before 1867 by a drift and long adit. It was closed in 1883 and the engine house was demolished in 1978. It is now visible only as earthworks.

Full Description

"Kennisham Hill Pit, disused" is marked on the 6" 1962 map. it was one of the Brendon Hills Iron Ore Company works. It had been worked before 1867 by a drift 150 ft deep and a long adit which emerged 350 yards to the east. The lodes were wide but the ground was soft and so needed much timbering. Little development until 1873 when a new drift (Curtis's - SS96303608) was sunk which connected with the original adit and reached l00ft by 1874. Ore was carried to Langham pit by means of an aerial cableway called "The Flying Machine". It was closed soon after but repoened in 1879, when it saw its greatest output; Curtis drift reached 468ft. A tramway was laid to Gupworthy Station, the trams being pulled by horses. The mine was finally closed in 1883, with the engine house being demolished in 1973. It had a rotary beam engine which did the pumping and the winding with one winding drum. [1-2] A water adit and well preserved entrance to the mine, inscribed "G. Collins Kennisham mine" are at SS96853595. [3] Engine house demolished 1978 but recorded. [4] There are earthwork remains visible of the mine workings. [7-9] A single granite block (former cylinder anchor stone) from the original engine house lies within a flat clear area adjacent to the designated picnic site, approximatley 200 metres to the east of the former Engine House. [10] The pumping and winding engine house was a copy of that at Burrow Farm. It became unsafe and was demolished in 1978, not 1973 as mentioned above. The building was surveyed in 1960 but the survey has not yet been published. [11-13] The mine was visited by the Russell Society in August 2015. Within the limited time period during which the Russell Society members were able to examine the mineralogy of the dumps (2.5 hours) seven minerals were definitely confirmed, with one “probable” and two “tentative”. Much more field work will be required to get a fuller understanding of the mineralogy. More sites will need to be sampled and detailed chemical analysis in the laboratory will be required. It is hoped to plan a return visit sometime in the future to resume this work. [14]
