An iron mine, which was started in the early 1800s, reworked in 1836 and again in 1858-1859. It was reopened in 1907, but no further production resulted.
The sett comprised two EW-trending lodes, which were worked from an adit and a shaft that extends only 12 fms below adit level. The lodes were slightly heaved by two NS-trending cross-courses, one of which carried a little torbernite near the intersection.
Between 1858 and 1859, the mine sold 426 tons of iron ore.
Dines refers to two tin lodes on an E-W trend about 15 fathoms apart at adit, that have been followed for about 60 fathoms.
