Copper was a major export from Parys Mountain on Anglesey which was, at its height, the largest copper mine in the world. Copper had been known about and mined since at least the Bronze Age with a sophisticated Bronze Age copper mine on the Great Orme near Llandudno. Smaller copper deposits worked worked in Snowdonia which had a flourishing copper industry from the early 1800s. Although exploited in the past, none of these minerals is mined on a commercial scale today.
