Some 2800 tons of baryte were produced from Barlocco Mine, mainly from the more northerly of two approximately east-west subvertical veins. The principal vein is 0.5-2.1 m thick and occupies a fault breccia traceable for at least 300 m in altered Silurian shale. The high-quality white baryte remaining on the dumps is accompanied by calcite and traces of chalcopyrite, malachite and bornite.
A little levelled and grassed-over waste down by the stream contains disseminated tetrahedrite-tennantite series, and occasional coatings of azurite.

Description: Five specimens were analysed by Stephen Moreton in 2026 using SEM-EDS. Two gave Sb > As, so were tetrahedrite. Two gave As > Sb, so were tennantite. One gave Sb = As, placing it in the middle of the series. All look the same visually, as disseminations in quartz.
