Notable minerals: Galena, Blende, Pyrite, Jamesonite and Bournonite.
Trewetha Mine, otherwise known as Wheal Boys, is an Antimony mine situated about threequarters of a mile southeast of Port Isaac, in St Endellion parish, North Cornwall. Trewetha is known to have been at work in the 1770's with reports of 95 tons of antimony raised between 1774 and 1776. The mine had a very chequered history closing and reopening on several occasions. In 1825 ore output from the mine was an average of 100 tons Antimony per year, with lesser amounts of the metal sulphides, Galena, Blende and Pyrite. After another period of abandonment the mine reopened in 1906.
There are also reports of fine specimens of Jamesonite (lead iron antimony sulphide) and Bournonite (copper lead antimony sulphide) occuring at the mine.
