The southern extension of the Harding vein in Coomb Height was once called Coombside vein.

The vein was worked from several levels to the valley floor and was stoped to surface on both sides of Grainsgill.

According to Hitchen (1934), bismuth minerals were most common in the 'west band of the Harding vein'.

β“˜ Dolomite
Formula: CaMg(CO3)2
Description: Cooper & Stanley (1990): "Smythe & Dunham (1947) published an analysis of 'ankerite' from the Harding vein, but with only 7.5 wt% Fe this represents a ferroan dolomite."

Formula: ZnS
β“˜ Stolzite ?
Formula: Pb(WO4)
Habit: slightly rounded bipyramids; drusy
Colour: pale olive brown; brownish
Description: Kingsbury reference. Cooper & Stanley (1990): "In 1950, Kingsbury & Hartley (MS) found stolzite as minute, slightly rounded, bi-pyramidal crystals of a pale olive-brown colour on iron-stained quartz 'outside the old main adit-level on the Harding vein' and as a brownish, drusy, parallel growth on scheelite from the Harding vein dumps."
β“˜ Strengite
Formula: FePO4 · 2H2O
Habit: glassy spherules
Colour: brown
Description: Cooper & Stanley (1990): "As minute, glassy, brown spherules on wolframite from an exposure on the Harding vein (det. BM(NH): XRD, D. McCallum, pers. comm.)."
β“˜ Tremolite
Formula: ◻Ca2Mg5(Si8O22)(OH)2
Description: Cooper & Stanley (1990): "'Sparingly in a fibrous form, as an alteration product, on metamorphosed diabase from the Harding vein' (Davidson & Thomson, 1951: 143)."
