The Ordnance Survey large scale 1:2500 mapping published in 1870 shows a mine entrance at the grid reference provided, with a spoil heap immediately to the south, together with the annotation ' Lead Mine'.


The Glen Chass mine was probably first worked in the late 18th century as a report of 1819 describes it as for the time being abandoned.  The mine was reopened in the middle of the 19th century, at which time a shaft was sunk 170m NNW of the adit entrance (see 9498.00). 


Despite exploration and development the mine was not profitable and was abandoned in the 1860s following an underground collapse.
