The Penrhyn Du Mines are a collection of mines situated near Llanengan on the Llŷn Peninsula. It encompasses the Penrhyn, Assheton, Western and Tan-y-Bwlch mines. The whole region can be called Penrhyn Du which literally means "black headland".
Tan-y-Bwlch Mine was probably the richest of the mines with a recorded output of 8,722 long tons (8,862 tonnes) of lead ore, 450 long tons (460 tonnes) of zinc ore and 4,652 long tons (4,727 tonnes) of copper ore between 1873 and 1886.
There is a possibility that Roman miners were the first to mine the Penrhyn Du headland After any Roman mining the mines were rarely worked until the reign of Elizabeth I where the need for lead was high. In 1637 Thomas Bushel was asked by Charles I to inspect and report on the prospects for Welsh mining. In his report of that year Bushel states:
