Unitary authority : Flintshire
NGR : SJ19767290

Description :
Lead (1834-1848, New Caeau 1910-1912)

Geology
Carboniferous Limestone with chert beds.

Workings
The old Caeau, Rhydfudr and Llongle Mines worked the Pantypedw Vein from 1834-1848, but were abandoned due to water and poor ventilation. Between 1910 and 1912, The Holywell-Halkyn Mining and Tunnel Company worked the New Caeau Mine underneath the old workings, some 230yds east of Caeau Farm. The Caeau Engine Shaft was deepened from 124yds to 141yds through chert beds.

Evidence remains around Caeau Farm as grassed over shafts and mounds, which run in a north-west to south-east direction in two lines on either side of the farm itself. The largest shafts are at SJ19607295 and SJ19707295.

The Caeau Mine was unwatered by an incline rise to the Milwr Tunnel (Smith 1921).

Two shafts remain to the north-east of Dafarn-Dywll at SJ19507275.

Transport
No evidence.

Power
Smith (1921) refers to the Caeau Engine shaft, and a whimsey at a separate drawing shaft.

Processing
No evidence.

Other features
No evidence.
