Formed through the merger of Tolcarne and Rose Cliff Mines, later renamed New Wheal Rose. It operated in the area between the cliff edge at Tolcarne Sands and Whitegate Road, working three lead-bearing lodes. Two of these lodes trend northwest and are approximately 400 yards apart, cropping out in the cliffs. The third lode trends east-northeast, intersecting the others inland.
According to Hamilton Jenkin, the area was worked from shafts in the Tolcarne section of the mine, previously known as Wheal Narrow. However, Dines notes that development seems to have primarily occurred on adit level, approximately 150 fathoms on the northwest-trending lodes, from the cliffs inland, and about 50 fathoms on the east-northeast-trending lode, extending from the end of the drive on the more westerly of the northwest-trending lodes. This development may pertain to the Rose Cliff section of the mine, which cannot be identified presently.
