The Surprise prospect is situated on Glacier Creek at 990 metres elevation above sea level in the Slocan Mining Division. The property consists of three forfeited Crown grants, (Lots 6334 to 6336) and one Reverted Crown grant (Elated, Lot 6333). The main showing is on Lot 6334.

Regionally, the area lies within the Kootenay Arc near the margins of the Ancestral North American Terrane. The Kootenay Arc is a curving belt of highly deformed metasedimentary and metavolcanic rocks which includes the Upper Proterozoic Horsethief Creek Group, the Eocambrian Hamill Group, the Lower Cambrian Badshot Formation, and the lower Paleozoic Lardeau Group. The volcano-sedimentary sequence is intruded by numerous Ordovician, Devonian and Mississippian granitoid plutons. The rocks have undergone regional metamorphism to middle or upper greenschist facies (Paper 1993-1).

The prospect consists of three short adits driven along quartz veins within fine grained, dark grey and green schists of the Index Formation of the Lardeau Group. On the property, rocks of the Lardeau Group strike northwest and dip 60 degrees east. The occurrence is on the east limb of an overturned syncline that plunges 10 to 15 degrees northwest.

Mineralization consists of clusters and irregular masses of tetrahedrite in milky white quartz. Sphalerite, galena, pyrite and chalcopyrite occur in minor amounts. The veins are subparallel to the schistosity and dip at slightly shallower angles. Between 1923 and 1954, a total of 1196 tonnes of ore were mined from the prospect which yielded about 1.23 million grams of silver, 560 grams of gold, 10,108 kilograms of zinc, 9798 kilograms of lead and 289 kilograms of copper.
