In the 24 years since the club's formation, the GCC have re-opened ten important mines in which 26 miles of passage have been explored. The club's chief activity is the re-opening of old lead mines in Flintshire and Denbighshire where several major excavations are currently under way. Access agreements are in place for the Milwr Tunnel and Halkyn mines and the club regularly take visiting clubs from all over the country into these workings.

Most of Halkyn Mines are reached via the Milwr (sea-level) Tunnel. Exploration then centres on pushing upwards. This photograph shows a passage and stope 400 feet above the Milwr Tunnel, in the Great Halkyn Vein, some two miles from the entrance. The surface is a further 400 feet above.
