Clogau Gold Mine
The Clogau (pronounced "clog-eye") Gold Mine (sometimes known as the Clogau St David's Mine) is a gold mine situated in Bontddu, near Barmouth, in Gwynedd, north-west Wales.
==History==
Originally a copper and lead mine, gold extraction began at the Clogau Gold mine in 1854, when the then director of the Clogau copper mine, Mr Goodman, unwittingly discovered gold. From 1862 until 1911 the Clogau Gold Mine produced 165,031 tonnes of gold ore resulting in 78,507 troy ounces (2,442 kg) of gold in what was known as the 'gold rush' period.
In 1989 the Clogau Gold Mine was re-opened by William Roberts, founder of Clogau Gold of Wales Ltd. Gold extraction re-commenced between 1992 and 1998, with small-scale mining providing the gold for Clogau Gold jewellery. Mining eventually ceased in 1998 due to high cost of mining and diminishing quantities of gold being found.
The small supply of gold extracted from Clogau and surrounding mines, combined with increased demand for Welsh gold both domestically and internationally have made gold produced at the Clogau mine amongst the most valuable in the world. Clogau Gold of Wales, who use gold sourced from the mine in all of their products have introduced the distinctive rose-coloured gold extracted from the Clogau mine to an international market.
