The sole record of this mine is a sett plan created in the interim of the Old (18th cent) and new (19th cent) workings of Hallenbeagle mine. The main set of workings on Hallenbeagle Old Lode were drained by the continuation of the Wheal Rose adit, driven into the mine from the adjacent workings of Trewan (Truan); now somewhere between Prima Bakeries and Smokey Joes.
