Originally called Trinity Mine in 1797 when Philip Rashleigh obtained fine specimens of crystallised goethite for his collection.

Subsequently renamed Restormel Royal Iron Mine after a visit from Queen Victoria and Prince Albert in September 1846. The mine captain described how Prince Albert "took the pick, and he thawed it like a man! and he got a bit of ore." On the departure of the Royal party, 120 miners "were ready to cheer 'em as they drove off, all red like Injians from the red of the main [lode] and we did cheer to be sure, as never was before". After the royal visit, Queen Victoria commanded 50 gold sovereigns to be distributed among the miners.

Two lodes trending northwards from near Lostwithiel through Lanhydrock. Mostly worked from extensive levels. Produced 128,000 tons iron ore 1855-83.

Restormel Royal Iron Mine closed in 1883.
