Clwyd Metal Mines Survey

Rhydymwyn Cefn Mawr

Rhydymwyn Cefn Mawr lies in the community of Cilcain in the county of Flintshire. It is located at Ordnance Survey national grid reference SJ20806630. The mine is recorded in the CPAT Historic Environment Record as number 18195 and this number should be quoted in all correspondence.

Lead/Zinc/Iron (1900-1902)

Geology
The mine site lies on a bed of Holywell shales close to the River Alyn.

Workings
Close examination of the workings was impossible as the area is a highly fenced off woodland within an Industrial Estate. It was only possible to verify that the shaft marked by the OS at SJ20856650 still exists as a mound. Documentary evidence refers to this as the Rhydymwyn Iron Shaft. There are no other traces of mine workings although the site represented the later workings in the Rhydymwyn area by the Brunner Mond Company.

Transport
No evidence.

Power
The Iron shaft was engine powered with an A-frame for winding.

Processing
No evidence.

Other features
No evidence.

Comments
The Mine Ownership for 1900-1902, during its brief operation was Brunner Mond & Co.L.T.D., who apparently abandoned it in 1902. Brunner Mond had developed a method of processing Zinc ore. Actual mining on the site may only have been a very small part of their operations in the vicinity.
