Alltgoch (Frongoch) Lead Mine (United Kingdom)

A very small mine to the East of Allycrub. Three short trials on a scenic ridge above Talybont. The first trial in very low and leads to a dead end, the second one is hugely tall - about 10 feet tall - and leads directly to a small chamber where a level leads for about 5 feet from a ledge half way up. The main adit twists right and leads to a dead end.
The third trial is partly blocked and doesn't lead anywhere.
