A small mine, and by far the most easterly mine within the Merioneth gold-mining area, being isolated over 6 miles to the east of the northerly group of mines that includes the well-known Gwynfnydd Mine.

Castell Carn Dochan was a relatively late discovery in the area, a company being formed in Manchester in 1863 to work the mine after gold was discovered here by a 12 year old boy, although many quartz boulders showing visible gold were scattered on the hillside.

Operations between 1864-66 produced 1508 ounces of gold from 3158 tons of quartz, with fine specimens being found underground. However, yields declined by 1866, and the plant was sold in 1876 following a winding-up order.

Later revived, the mine worked on a small scale till 1905. Records show 12.5 ounces of gold from 50 tons of quartz in 1889, and 393 ounces of gold from 2638 tons of quartz between 1895-98. The deep adit, north-east of the mine from near the river, was completed about 1901.

Castell Carn Dochan was the 4th most productive of the Merioneth gold mines. Some lead was also produced.
