The White Star occurrence is located between Birch and Boulder creeks which both drain into the west end of Surprise Lake, about 16 kilometres northeast of the community of Atlin.

The showing consists of quartz veins which are hosted in variably metamorphosed rocks of the Mississippian to Triassic Kedahda Formation of the Cache Creek Complex. The rocks consist of chlorite and sericite schists, quartzites and minor limestone. Near the occurrence is a large body of quartz monzonite often referred to as alaskite. The body is part of the Late Cretaceous Surprise Lake batholith (Surprise Lake Plutonic Suite) and has variable textures. It has imparted the metamorphic fabrics on the Kedahda Formation rocks and in places has silicified the limestone pods. Some skarn-type mineralization has been reported in the area of the occurrence.

The quartz veins strike at 070 degrees and dip 80 degrees to the northwest. They are well defined and have consistent orientations. The vein is 1.5 to 2 metres wide and is often banded with darker material, particularly towards the hangingwall margin. Mineralization is spotty with minor galena, pyrite and sporadic visible gold.

Exposed mineralization in trenches in skarn-type zones comprises pyrite, chalcopyrite, galena and sphalerite. Gold values were reported as sporadic, varying from nil to 13 grams per tonne gold. Silver assays have been as high as 308 grams per tonne, taken during the development work of 1904 (Minister of Mines Annual Report 1904, page G77).

In 1904, a 7.6 metre long crosscut tunnel was driven to intersect the quartz vein which was then followed by a drift to the east for 18.3 metres.
