Geology
The Mount Halkyn and West Halkyn Mines worked the eastern end of the California Vein, which cut east to west across the Carboniferous Limestone of the Halkyn mountain.

Workings
The workings appear to run eastwards towards the wireless station from a reservoir (SJ20406955) near Pant-y-ffrith, which is surrounded by shafts and spoil. The earthworks cover a very large area, but the main area of working seems to surround a large shaft capped with concrete, which has a stone wall revetment to the south side of it, being a likely building structure (SJ20356995).

The sett was worked from 1928 by the Halkyn District United Mines.

Transport
The underground diesel railway of the 1928 company served the sett.

Power
A reservoir, which contains water (SJ20406955) forms the top level of a series of watercourses that run down to the main mine area.

The sett was drained by the Deep Level Tunnel.

Processing
No evidence.

Other features
No evidence.
