The Sunbeam showing is located on the west side of Fredrick Arm, north of Owen Point. The exact location is unknown, however, the original claims cover the ground from the beach, on Fredricks Arm, up the mountainside to the vicinity of the Bluebells (L.235) group of crown grants (Minister of Mines Annual Report 1923, page 254).

The area is underlain by a package of uncorrelated Paleozoic and/ or Triassic metamorphosed sedimentary rocks within diorite, grano- diorite and quartz diorite of the Jurassic to Cretaceous Coast Plutonic Complex. At lower elevations the sediments consist mainly of massive grey limestone locally metamorphosed to a clean white crystalline marble. At higher elevations argillite becomes more prominent. The argillite is generally weakly to strongly hornfelsed with a corresponding increase in biotite and chlorite content.

The mineralization at the Sunbeam occurs as gold-bearing quartz veins with a strike of 325 degrees and dip of 80 degrees southwest. The mineralization consists of some free gold as well as gold values associated with pyrite and arsenopyrite (Minister of Mines Annual Report 1923, page 254).
