- Supergene: post-mining oxidation & weathering deposits
- Supergene: in situ natural oxidation & weathering deposits
- Dan-y-graig Quarry, Risca, Gwent: noted from galena-bearing veins by Alabaster (1983).
- Dolyhir Quarry, Old Radnor, Powys: microcrystals occur within cavities in part-decomposed intergrown tennantite and galena; associated with anglesite (D.I. Green, unpublished data).
- Dyfngwm Mine, Penegoes, Powys: on specimens collected by S.A. Rust (listed on Mindat website).
- Eaglebrook (Nantycagl) Mine, Ceulanymaesmawr, Ceredigion: on specimens collected by S.A. Rust (listed on Mindat website).
- Frongoch Mine, Devil's Bridge, Ceredigion: occurring as crystals (up to 3 mm) associated with anglesite in part-decomposed galena (Green et al., 1996).
- Hafan Mine, Ceulanymaesmawr, Ceredigion: on specimens collected by S.A. Rust (listed on Mindat website).
- Llangynog Mine, Llangynog, Powys: crystals (up to 1.5 mm) associated with anglesite in partly decomposed galena (S.A. Rust collection), also known from a specimen collected by J.S. Mason in 1995.
- Nant-y-blaidd Mine, Llangynog, Powys: 'in a galena-bearing vein' (Wedd et al., 1929).
- Ochrwyth Quarry, Risca, Gwent: noted from galena-bearing veins by Alabaster (1983).
- Parys Mountain, Anglesey: sulphur occurred in the long removed gossan (Lentin, 1800), as yellow veinlets associated with anglesite and a 'yellow-green, earthy lead ore', which Southwood & Bevins (1995) tentatively suggest may have been the pyromorphite described by Greenly (1919).
- Penrhiw Mine, Ystumtuen, Ceredigion: as blocky crystals (up to 1 mm) with covellite in altered galena (Mason & Green, 1995).
