Cooper & Stanley (1991):
"This property is adjacent to the Roughton Gill mine and exploits the eastward extension of the Roughton Gill (South) vein. It was begun in 1845, and three crosscuts were driven south to cut the vein. Although promising shoots of pyromorphite and cerussite were found early on, the mine proved to be a financial disaster. The crosscuts, a shaft, and levels parallel to the vein were all cut on the assumption that rich primary ores would be found when the vein was opened up. In fact, the lode was almost barren and the heavy investment, largely made by the Caldbeck Fells Consolidated Lead and Copper Mining Company, was wasted. The mine was abandoned in 1868.
In the mid-1970's the Cornish mineral dealer Richard Barstow opened a vein exposure near the High Level of the Mexico mine and made a find of excellent pyromorphite of "old time" quality. The locality was subsequently worked by other collectors and further good material was discovered. The site is now backfilled."

Standard Detailed Gallery Strunz Chemical ElementsDetailed Mineral List:
| ⓘ Anglesite Formula: PbSO4 References: |
| ⓘ 'Bindheimite' Formula: Pb2Sb2O6O Habit: powder Colour: yellow Description: Cooper & Stanley (1990): "As a yellow powder with pyromorphite, cerussite, and wulfenite in cavities in quartz from the Low level dump in Todd Gill (M.P. Cooper Collection, det. Leicester Univ.: XRD)." |
| ⓘ Brochantite ? Formula: Cu4(SO4)(OH)6 Description: Kingsbury reference. Cooper & Stanley (1990): "Kingsbury & Hartley (MS) list brochantite from 'Todd Gill'; Kingsbury (MS1) gives the locality as 'just east of Roughton Gill lead works. Old cross-cut at the foot of the gill, driven on the north vein', i.e. probably the Mexico mine Low level." References: |
| ⓘ Cerussite Formula: PbCO3 Description: Cooper & Stanley (1990): "Described as 'crystallized and acicular' by Greg & Lettsom (1858: 391). A mining report of 1865 (Shaw archive, Carlisle, D/Sh/1/9) describes the 60fm level 'driven 15fm [27m] all in ore worth up to [2 tons] per fm all carbonate'." References: |
| ⓘ Chalcocite Formula: Cu2S References: |
| ⓘ Chalcopyrite ? Formula: CuFeS2 |
| ⓘ Corkite Formula: PbFe3+3(PO4)(SO4)(OH)6 Habit: pseudo-cubic or pseudo-octahedral crystals up to 1.5mm across Colour: dark brown to almost black Description: Cooper & Stanley (1990): "From debris near the High level, on a few specimens collected in 1976 as dark brown to almost black, pseudo-cubic (or pseudo-octahedral) crystals to 1.5mm across, scattered on lustrous black goethite in cavities in gossany quartz, associated with small amounts of later, green, pyromorphite (D.R. Middleton, pers. comm.; det. BM(NH): XRD). A further specimen was later confirmed as corkite by XRD and semi-quantitative analysis at the Royal Museum of Scotland (M. Wirth, pers. comm.)." |
| ⓘ Cuprite Formula: Cu2O Description: Listed as 'red oxide' in Shaw (1970) (Cooper & Stanley, 1990). |
| ⓘ Galena Formula: PbS |
| ⓘ Goethite Formula: Fe3+O(OH) Habit: botryoidal Colour: black Description: Cooper & Stanley (1990): "Black, botryoidal, goethite forms the matrix for corkite. The lustrous surface is criss-crossed by minutely globular goethite which has grown along minute cracks like strings of tiny beads (D.R. Middleton Collection)." |
| ⓘ Langite Formula: Cu4(SO4)(OH)6 · 2H2O Habit: pseudohexagonal Description: Cooper & Stanley (1990): "As small pseudo-hexagonal crystals (det. University of Manchester Institute of Science and Technology (UMIST): IR, R.S.W. Braithwaite, pers. comm.)." |
| ⓘ Linarite Formula: PbCu(SO4)(OH)2 References: |
| ⓘ Malachite Formula: Cu2(CO3)(OH)2 References: |
| ⓘ Mimetite Formula: Pb5(AsO4)3Cl Habit: rounded Colour: brown Description: similar to, but distinct from, Dry Gill "campylite" have been found on the dumps from the High Level (Cooper & Stanley, 1990-1991). References: |
| ⓘ Mimetite var. Campylite Formula: Pb5(AsO4)3Cl Description: Rounded aggregates of the 'campylite' habit are more common here than in specimens known to be from the main Roughton Gill mine, but they do not mimic Dry Gill 'campylite' in form or association sufficiently to be confused with it. |
| ⓘ Molybdenite Formula: MoS2 |
| ⓘ Native Gold ? Formula: Au Description: Kingsbury reference. References: |
| ⓘ Plumbogummite ? Formula: PbAl3(PO4)(PO3OH)(OH)6 Habit: minutely botryoidal crusts Colour: pale smoke-brown to grey Description: Kingsbury reference. Cooper & Stanley (1990): "As brown to smoky grey minutely botryoidal crusts on quartz, with later yellow-green rounded pyromorphite crystals, from the Low level dumps in Todd Gill (Kingsbury Collection, BM(NH); Kingsbury & Hartley, MS)." References: |
| ⓘ 'Psilomelane' References: |
| ⓘ Pyromorphite Formula: Pb5(PO4)3Cl Habit: prisms; crusts of globular aggregates; rounded Colour: oil yellow; golden yellow; greenish-yellow; emerald green; honey brown; bi-coloured (orange and green) References: |
| ⓘ Quartz Formula: SiO2 |
| ⓘ Tenorite ? Formula: CuO Description: Cooper & Stanley (1990): "The 'grey oxide' of copper recorded by Shaw (1970) may have been tenorite." |
| ⓘ Wulfenite Formula: Pb(MoO4) Habit: plates; rounded, steeply bipyramidal; tabular Colour: orange Description: From a vein exposure above the Mexico mine High Level (D.R. Middleton Collection, M.P. Cooper Collection, pers. comm., 1986, det. BM(NH): XRD, 1989). References: |
