Crustal's Los-Hamra district is part of the Los-Överturingen metallogenetic area in southern Hälsingland. The area has a long exploration and mining history and has documented occurrences of several metal types, including gold, silver, copper, zinc, lead, uranium-molybdenum, and copper-cobalt.

The district lies within the Bothnian Basin and is characterised by metasedimentary rocks where skarn- and sulphide-bearing rock environments constitute important exploration targets.
