At the northern end of Kerriack Cove cove, an E-W lode bearing
quartz,
sphalerite,
chalcopyrite and
galena was worked, principally for zinc, as part of the Wheal Lushington sett.
Towards the middle of the cove, an E-W trending mineralized fissure vein crops out at the base of the cliff. Carrying mainly
sphalerite,
pyrite, green
chlorite and
quartz, with minor
galena and
chalcopyrite, small vugs were also found to contain occasional cream-brown spherules of
malhmoodite up to 0.15 mm in diameter.The brown colouration is due to iron staining.
