As of 2025, working quarry nowdays producing mainly slab.**

Substantially disturbed by later operations, with one contemporary building surviving relatively intact. The ruins include a mill featuring a wheel pit, barracks, and various other buildings,

Worked Cambrian slate distinguished by its notably good colour. Operations relied on a water-powered mill equipped with a Hunter saw for processing. Finished slate was carted to the River Dwyryd for transport, making this likely the last quarry in the district to depend on river transport, which continued until 1868. A tramway connection to the Great Western Railway was planned in 1883, though construction proceeded only as far as the site boundary, leaving the connection uncompleted. Small-scale extraction continued into the 1980s.

The BOAT is driveable by normal car from Tomen y Mur to the quarry.
