Brown pyromorphite is rare in the British Isles and the presence of large (exceptionally to 25 mm long) thick prismatic crystals on the extensive dumps at Frongoch suggests that this is the locally to which Greg and Lettsom refer. Colours range from green (extremely rare) to mauve and chocolate brown.

Mines in Waleshave dominated gold production in the British Isles for as long as reliable records have been kept. With the exception of Ogofau, all the producing mines were in the Dolgellau Gold Belt,where the two largest and most famous mines were Clogauand Gwynfynydd.The mineralisation is typical of turbidite hosted vein style deposits.
