Llwyndu Copper Mine – view from the mine manager’s house or office. The entrance to the stopes of the old workings can be seen above the spoil heap, top centre. The dressing floor, middle right, was where the ore was cobbed by a team of twenty girls.

Llwyndu or Crib Ddu Copper Mine is located at the top of the hill above Sygun Copper Mine and was worked for a time as part of the Sygun enterprise. In fact, the company owning Sygun mine changed its name to the Llwyndu Mine Company in 1839. Llwyndu Mine was, however, only in operation for around nine years and the site was abandoned by 1844.

  1. I love the top shot! The stopes are very interesting, too. I think I will have to lay the work aside and have a look at this place. It was on our list, but you beat us to it! Super shots.
