The Mine was opened (or reopened) in 1853 by an Iron smelting company from south Wales. Initially mining Goethite/Hematite, this giving way to Siderite at a shallow depth. The discontinues east-west lode structure hosted in Devonian Slates also contains sparse Copper and rare Bismuth mineralization. The highest output of Iron Ore was in 1877 with 47,000 tons for all the Brendon Hill Iron mines. The mine closing in 1883 due to imports from Spain and the unsuitability of Siderite as an ore. There was an abortive attempt at revival in 1907.
Dumps and collapse stopes workings in forested area 500 yards north-west of picnic site and 3 miles east-south-east of Wheddon Cross, a very recent Somerset village dating from the 1820s

Standard Detailed Gallery Strunz Chemical ElementsDetailed Mineral List:
| ⓘ Atelestite Formula: Bi2(AsO4)O(OH) Colour: Colourless-White Description: EDS partly identified at the ROM, but might be Tetrarooseveltite. References: |
| ⓘ Baryte Formula: BaSO4 Description: Very thin platy colourless micro-crystals <0.5mm References: |
| ⓘ Bismutite Formula: (BiO)2CO3 Description: Bismutite from Kennisham Iron Mine is found as inconspicuous white to light yellow and yellow green masses to 2cms,and micro balls <1mm also as platy square, and tapering prismatic crystals <0.75mm. Bismutite commonly replaces a metallic grey Bismuth mineral. The matrix is a mixture of Goethite some Quartz and a very micaceous slate. Confirmed by XRD at the NHM, London 2012. References: |
| ⓘ Bornite Formula: Cu5FeS4 Description: Masses to a few mm as a purple-red (horse flesh ore) tarnished alteration of Chalcopyrite References: |
| ⓘ Brochantite Formula: Cu4(SO4)(OH)6 Description: Found as emerald green bladed to prismatic tiny micro-crystals, associated with Chalcocite rich matrix, with Langite and Connellite. References: |
| ⓘ Chalcocite Formula: Cu2S Description: Massive metallic grey masses (easily confused with a BiCu sulphide at this mine) to a few mm in dump material, as an alteration of Chalcopyrite References: |
| ⓘ Chalcopyrite Formula: CuFeS2 Description: Metallic yellow thin stringers in siderite with enclosing quartz, and as metallic grains in Goethite some possible altered to Chalcocite and Bornite. References: |
| ⓘ 'Chlorite Group' References: |
| ⓘ Chrysocolla Formula: Cu2-xAlx(H2-xSi2O5)(OH)4 · nH2O, x < 1 Description: As a greenish resinous replacement of malachite References: |
| ⓘ Connellite Formula: Cu19(SO4)(OH)32Cl4 · 3H2O Description: Found on two Chalcocite rich specimen with Brochantite and Langite. References: |
| ⓘ Cuprite Formula: Cu2O Description: Cuprite rarely forms crystalline masses to a few cms encrusted with green Malachite, with remnant Chalcopyrite and Chalcocite, very minor amounts of connellite are found with the Cuprite. References: |
| ⓘ Goethite Formula: Fe3+O(OH) Description: Common as micro-crystals and cross-fibrous masses with a low botryoidal surface, to several cms from the dump. References: |
| ⓘ Langite Formula: Cu4(SO4)(OH)6 · 2H2O Description: Found on Chalcocite rich specimens as twinned and bladed micro-crystals References: |
| ⓘ Malachite Formula: Cu2(CO3)(OH)2 Description: Occasionally as botryoidal crusts to 1cm thick, also as radial fibrous acicular crystals to afew mm,and scattered balls to 2mm dia. |
| ⓘ Pyrite Formula: FeS2 Description: Veinlets to 5m wide in Siderite References: |
| ⓘ Pyrolusite ? Formula: Mn4+O2 Description: As black crusts, occasionally with botryoidal from covering areas to 30cms from the dump. Specimens my infact be mixtures of undefined Mn species of which Pyrolusite my be present. |
| ⓘ Pyromorphite Formula: Pb5(PO4)3Cl Description: So far found as two isolated colourless prismatic crystals to 1mm.
The crystals are probably Pyromorphite. References: |
| ⓘ Quartz Formula: SiO2 Description: A common component of the vein stuff, occasionally as epimorphs after siderite, and needle like crystals to a few mm. References: |
| ⓘ Siderite Formula: FeCO3 Description: Rarely found unoxidised, dose not appear to form crystals; only found as cleavages enclosed in quartz to several cms. References: |
| ⓘ 'Wad' Description: Black to dark grey veins in the county rock, some times forming botryoidal masses and stalactitic forms. Common as thin veinlets in the micasious country rock. References: |
| ⓘ Wittichenite Formula: Cu3BiS3 Description: Occurs as light to dark metallic grey massive mineral in goethite-hematite gossan usually extensively altered to yellow bismutite. References: |
