Smallcleugh mine is recorded to have been developed from 1770 for a short time, working a series of veins and strata-bound replacement deposits (flats) believed to have been first encountered in 1776 associated with the Handsome Mea and Smallcleugh veins. Although the mine does not appear to have gotten into its stride until 1787, several other veins and flat deposits were also developed before the mine closed in the early 1900s. In 1963 an abortive attempted was made to locate further ore reserves. The most well-known account is the dinner held underground by the Masonic Lodge in the so-called Ballroom Flats in 1901. The first amateur exploration of the mine may have been in the late 1960s.

Smallcleugh mine in the North Pennine Orefield is well known amongst British mineral collectors for good examples of galena, sphalerite, ankerite, and calcite, and to a much lesser extent quartz, all of which have been collected for many years since access was regained. Excellent specimens of single black complex sphalerite crystals to 1.5cm or so on white matrix were collected from a replacement deposit above the so-called Hydraulic shaft. Single galena crystals to 4cm could be collected from cavities in the strata-bound replacement deposits (flats) and veins. Less well known are the secondary species: secondary minerals mostly of zinc, copper, lead, and iron, rare nickel, and manganese have occasionally been found. Many of the secondary minerals from Smallcleugh would be only of interest to micro-mineral collectors. Many of the flat deposits now have modern names such as Wheel Flats (from a set of ore cart wheels found there, the old name may have been Browns Flat), while Whit Hudsons Flat and Hetheringtons Flat and cross-cut are possibly an original name. Other modern names are Incline Flats (an incline level leads into these workings), Old Fan Flats (parts of a ventilator fan found here), New Fan Flats (near the Old Fan Flats), North End Flats (?), Smallcleugh Main Flats (after the mine), The Ball Room Flat (named after a Victorian Masonic dinner party held there), Zinc Flat (from a high sphalerite content), High Flats (above the Smallcleugh Horse Level), Proud's Sump Flat (after the sump near these Flat workings), and Gullyback Flats (?). The rises and sumps appear to have mostly retained their old names, e.g. Spottiswood, Proud's, and Luke Halls.

Detailed Mineral List:

Ankerite
Formula: Ca(Fe2+,Mg)(CO3)2
Colour: White to creamy
Description: Ankerite is the most common constituent of the metasomatic deposits in this mine and many others in the orefield. The colour is white-creamy in unoxidized specimens showing typical saddle shaped crystals to 1cm. Oxidised examples from the Nenthead mines varies in colour from pale creamy brown and yellow to black.
Reference: Dunham Sir K C, Geology of the Northern Pennine Orefield, Vol 1, Tyne to Stainmore. HMSO
Annabergite
Formula: Ni3(AsO4)2 · 8H2O
Colour: white to very pale green
Description: Some annabergite from this mine is Sb enriched. (Pale green translucent balls and small botryoidal masses, where at first thought also to be annabergite, furthere anaysis has found Mg, Ni and Ca)
Reference: Sb rich annabergite Natural History Museum London, and S Rust Collection.
Aragonite
Formula: CaCO3
Colour: Colourless to white
Description: Forming radial acicular white colourless crystals to 0.5mm, and small mats of crystals to 1cm+.
Reference: S.Rust collection
Baryte
Formula: BaSO4
Colour: Colourless to tinted yellow
Description: The Smallcluegh Mine lays mostly out side the Baryte Zone. There for baryte is not at all common from the mine, and may be considered rare. Baryte from this mine is restricted to very few areas forming as a primary and secondary mineral.
Reference: S.Rust Collection
Beaverite-(Cu)
Formula: Pb(Fe3+2Cu)(SO4)2(OH)6
Colour: Yellow to brown
Description: Usually as a yellow powdery crust to seveal cms, and as pustules to 4mm dia. Very rarely forms sparkling vitreous crystal druses composed of minute yellow to yellow-brown micro-crystals
Reference: S.Rust Collection
'Bindheimite'
Formula: Pb2Sb2O6O
Colour: Dirty yellow
Description: Identified while investigating small nickel bering ankerite veinlets in the mine. Forms as very rare dull yellow pseudomorphs after probable ullmannite crystals.
Reference: S. Rust collection
Bottinoite
Formula: Ni2+Sb5+2(OH)12 · 6H2O
Colour: Light blue-green
Description: Bottinoite from the Smallcleugh Mine is comparable with the same mineral from Hendra Fellen Mine in Mid-Wales in terms of crystal form, although only found on 7 specimens from Smallcleugh Mine.
Reference: Nat Hist Museum London and S.Rust collection
Brianyoungite
Formula: Zn3(CO3,SO4)(OH)4
Colour: White
Description: Specimens of hydrozincite from this mine should be tested to confirm that they are not brianyoungite. Some of the brianyoungite crystals associated with a small nickel rich area in the mine are tinted pale light green, possibly due to a very small amount of Ni in the chemical structure. It only takes a very very small amount of Ni to give some minerals the green colouration.
Reference: Mineralogical Magazine: 57:665-670.
Brochantite
Formula: Cu4(SO4)(OH)6
Colour: Emerald green
Description: As emerald green scattered micro-crystals and small thin drusy crusts covering areas to 1cm +. Associated with gypsum, beverite-Cu, schulenbergite, and possible serpierite.
Reference: University Manchester Museum, and NHM London
Calcite
Formula: CaCO3
Colour: Translucent white to colourless
Description: A common mineral throughout the mine, forming crystals to 3 cms in diameter displaying major shallow pyramid faces with minor development of the prism faces. Commonly forming crystals richly scattered over an ankerite matrix. An area near the Bogg Shaft, from a brecciated area has in the past furnished cabinet size specimens of typical calcite crystals to 2.5cm dia.
Reference: Collected by many collectors over many years .
Cerussite
Formula: PbCO3
Colour: White
Description: Occurs as a minute crystalline alteration of galena,as micro prismatic, and bladed twinned crystals <0.4mm.
Reference: NHM London & S. Rust Collection.
Chalcanthite ?
Formula: CuSO4 · 5H2O

Description: So far only found on a few micro-specimens derived from a specimen collected in Nov 2010.
Reference: S.Rust Collection
Dolomite
Formula: CaMg(CO3)2
Colour: White to colourless, yellow.
Description: Most of the specimens which have been classified as dolomite are actually ankerite. But dolomite has been found as Zn/Mg enriched crystals associated with a nickel berring area in the mine. Tests should be under take to confirm that a specimen is dolomite.
Reference: Dunham, Sir K C, Geology of the Northern Pennine Orefield, Vol 1 Tyne to Stainmore. HMSO. Zn/Mg rich dolomite S.Rust Collection
Epsomite ?
Formula: MgSO4 · 7H2O

Sphalerite
Formula: ZnS
Colour: Black, dark brown
Description: Specimens are dark brown to black due to the presence of iron in solid solution. Small crystals less than 2mm are sometimes of the ruby variety. Of particular interest and great rarity are specimens from the replacement deposit above the Hydraulic Shaft, which have fossils coated by white calcite and sprinkled with black sphalerite crystals to 1cm. The deposit was originally discovered by David Lloyd, and Richard Barstow in the 1970's. David was testing the level wall for hollow sounds indicating a possible cavity, when part of the wall collapsed in leading to this remarkable deposit.
