Silurian and Ordovician. The Van lode has been exploited on a vein striking ENE. The mineralisation is mainly chalcopyrite in a quartz and calcite gangue. There is some sparse galena.

There are trials and opencuts on the outcrops. A crosscut and deep adit with levels connect to a shaft. Cummings Engine shaft SN88608570 is the latest feature and is still open as is one of the levels above.

Pack horses were used to transport ore to Garreg on the River Dovey in the 18th century.

A 30ftx3ft waterwheel was used for pumping.

The 19th century dressing floors are believed to have been situated where Geufron Farm is now located SN88288565. No obvious remains survive.
