Estimated Grid Ref. North Wheal Wrey? (Collins) Situated southwest of Gang, this small lead mine eventually encompassed North Wheal Wrey and Julia, undergoing a name change to Trebeigh Consols. The shaft, aligned with the strike of New Trelawny Lode, likely worked on its western extension. In 1877, the mine yielded 10 hundredweight of silver ore. The grid reference indicates the location of the shaft dump. Although the engine house ruin, partially collapsed but still extant in 1963, has since vanished.
