Grid ref. is estimate of Adit Lode portal.

From Dines:

An old mine, that has been tried from time to time, situated three-quarters of a mile S.W. of Carnmenellis hamlet (6-in. Corn. 70 N.W.) and immediately west of Calvadnack Mine.

The workings are reputed to be deep, but the plan (Α.Μ. 7184, dated 1921) shows workings only at adit level. Quarry Lode, consisting of nearly vertical, parallel veins, close together and trending N.E. is exposed in a quarry just south-west of White Alice farm.

The veins of dark tourmaline peach and quartz in granite country are said to carry 8 or 9 lb. of black tin per ton. From a shaft sunk in the quarry the adit drive extends 5fms . S.W. and 28 fms . N.E. At 22 fms. N.E. of the shaft a crosscut 11 fms. N.W. meets another lode that has been driven on for 18 fms . N.E. From the end of the south-west drive on Quarry Lode, a crooked crosscut meets at 25 fms. S.W. of the shaft, a third lode. This courses E. 10° N. and has been followed for 50 fms . S.W.

South of these workings is Adit Lode, coursing E. 20° N. and almost in alignment with Engine Lode of Calvadnack Mine. It is opened up by an Adit Level commencing about 340yds. S.W. of White Alice farm and extending 235 fms . E.N.E. There are two shafts, No. 1 at 230yds. S. by E. of the farm, 20 fms. deep to adit, with a drive, called No. 1 Level, about 20 fms. E. from it, and No. 2 at 270 yds. S.E. of the farm and 120 yds. W.S.W. of Engine Shaft of Calvadnack Mine; the level is 27 fms. deep here but it is not clear whether the shaft is connected and has been partly filled, or whether it is not quite as deep as the adit. Some stoping has been done near No. 1 Shaft, below No. 1 Level, but the full extent of this is not known. From the adit at No. 2 Shaft a crosscut 63 fms. N. by W. meets another lode on which there is a short drive.

There are no known records of output.
