Situated about three-quarters of a mile S.E. of St. Columb Minor (6-in. Corn. 40 N.W.), this is little more than a trial on a N.-S. lead lode underlying 28° Ε. Α plan (A.M. 127, dated 1847) shows drainage adit commencing near the alluvium, 320 yds. S. of Rialton Barton and driven 75 fms. S.W. as a crosscut to an adit shaft; there it turns south at Adit Level for 225 fms ., passing a trial shaft at 70 fms. and Engine Shaft at 160 fms. The latter is vertical to the 70-fm. Level below adit (14 fms.), passing through the lode between the 32-fm. and 45-fm. levels. The 20-fm. Level opens up the lode in two places, one for 18 fms. N. and 30 fms. S. of the shaft, and the other for 53 fms., commencing 16 fms. farther north, reached from winzes from Adit Level. The 32-fm. Level extends for 28 fms. N. and 30 fms. S. of the Engine Shaft, the 45-fm. for 55 fms. N. and 6 fms. S., and the 55-fm. for 40 fms. N.; the 70-fm. Level is short. There are only very small stopes on adit, the 20-fm. and the 32-fm. levels near the shaft. Veinstone in the dumps is of white vein quartz, banded and with radial comb structure, with some siderite and a few specks and moulds of sulphide ores. There are no records of output.
