The White Star mine lies in the Zeballos gold camp on a west facing slope, east of Spud Creek and approximately 5.1 kilometres northeast of the community of Zeballos.

The area is underlain by a Lower Jurassic Bonanza Group Island arc sequence of basaltic to rhyolitic volcanic rocks. Conformably underlying the Bonanza rocks are limestones and limy clastics of the Quatsino and Parson Bay formations, and the tholeiitic basalts of the Karmutsen Formation, all belonging to the Upper Triassic Vancouver Group. Dioritic to granodioritic Jurassic plutons of the Zeballos intrusion phase of the Island Intrusions have intruded all older rocks. The Eocene Zeballos stock, a quartz diorite phase of the Catface Intrusions, is spatially related to the area's gold-quartz veins. Bedded rocks are predominantly northwest striking, southwest dipping, and anticlinally folded about a northwest axis.

Recorded production for the camp totals 9465 kilograms gold and 4119 kilograms silver, from 652,000 tonnes of ore mined (Fieldwork 1982, page 291). Most production came from the Spud Valley (092L 013, 211) and Privateer (092L 008) deposits.

Five veins are recognized at the White Star mine, all within quartz diorite intruded by north to north-northeast striking feldspar porphyry dykes all related to the Eocene Catface Intrusions. The veins lie 300 metres east of the quartz diorite contact with calc- silicate altered tuffs of the Lower Jurassic Bonanza Group.

The veins follow shear zones that dip steeply southeast and strike approximately 040 degrees. The shear zones are up to 15 centimetres wide, the quartz veins contained in them are somewhat narrower. Diagonal gash veins, commonly filled with comb quartz, are common.

The Number One (Donaldson) vein, which with Number Two accounted for most of the mine's production, follows in part a 1.8 metre wide feldspar porphyry dyke. The veins contain moderate amounts of pyrite, galena, sphalerite, arsenopyrite and free gold in quartz gangue. Sulphide banding is common. The Numbers 3, 4, and 5 veins, located 60 metres west of the Donaldson Vein, are much narrower, averaging less than 3 centimetres.

Production between 1935 and 1942 totalled 1283 tonnes averaging 171.7 grams per tonne gold, 71.7 grams per tonne silver (Bulletin 27, page 77). Production between 1935 to 1957, includes 220,987 grams of gold, 92,531 grams of silver, 17,144 kilograms of lead with 1563 kilo- grams of copper and 30 kilograms of zinc.
