This and Old Brandley Mine exploited the Brandlehow lode for lead ore, with one utilizing shafts and levels located beside Derwentwater, while the other employed levels and opencast workings on the eastern slope of Catbells. Although primarily active in the 18th century, some of the shallow workings are believed to be much older. Ultimately, both mines were abandoned in 1891.

On the higher dumps of Old Brandley mine, white to pale lemon fluorite crystals, measuring up to about 3 centimeters, can be found alongside dull galena crystals, cerussite, and clusters of green pyromorphite in small crystals.
