Area west of Brighton Cross, where three northeast-trending copper lodes were worked. Wheal Cocke operated in the northern part of this area, while Wheal Wellington was situated to the south and west. However, the setts (mining areas) of these mines were closely adjoining, making it difficult to attribute the remaining surface traces with certainty to one of the mines. An overgrown dump in a field west of the road leading from Brighton Cross to Summercourt serves as a marker for this activity.

Historical records, including Barton (1966), indicate that Wheal Cocke was established in 1822, with the erection of a wooden engine house on the sett. In the following years, from 1823 to 1824, Wheal Cocke produced 495 tons of copper ore with an average grade of 8%, along with some lead ore and black tin. Unfortunately, the output of Wheal Wellington during this period is not recorded.
