Clwyd Metal Mines Survey
(also known as Rhydfudr, Llongle or New Caeau)
lies in the community of Halkyn in the county of Flintshire. It is located at Ordnance Survey national grid reference SJ19767290.
The mine is recorded in the CPAT Historic Environment Record as number 104128 and this number should be quoted in all correspondence.
Lead (1834-1848, New Caeau 1910-1912)
Carboniferous Limestone with chert beds.
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 shatfs remain to the north-east of Dafarn-Dywll at SJ19507275.
Smith (1921) refers to the Caeau Engine shaft, and a whimsey at a separate drawing shaft.
