The Clogau (pronounced "clog-eye") Gold Mine (also known as Clogau St David's) is a gold mine near Bontddu in North Wales.
The Clogau mine was opened to exploit the copper and lead veins in the area north of Bontddu.
The main gold-bearing vein was named the "St. David's lode", and in 1860 arrangements were made with the Crown Estate to work the gold commercially.
Alba Mineral Resources are now the majority owner of the mine and are currently drilling to assess the commercial viability of reopening parts of the mine.
Previous samples taken from a 200 metre long area returned gold grades of 30.2 to 263 grams per tonne,[5] suggesting that previously unrealised supplies of gold could potentially exist.
