A small brick-built structure is located on the northwest side of the first islet at Langness Point.  It forms the most substantial remains of mine buildings associated with copper extraction in the late 1800s.  The foundations of additional structures lie just to the east. None of the structures are marked on the Ordnance Survey 1:2500 First Edition mapping surveyed in 1867, so must post-date this survey.  


Copper has been mined from Langness from probably as early as the Bronze Age, since stone tools, of a type used to break up the ore, have been found throughout the area.
