The Christina occurrence is located on Mount Baldwin in the north western head waters of the Indian River.
The area occurs on the eastern edge of the Britannia- Indian River pendant, which hosts the volcanogenic deposits of the Britannia camp (MINFILE 092GNW003). The Britannia-Indian River pendant is mainly a calc-alkaline, sub-aqueous volcanic and sedimentary sequence of felsic to intermediate pyroclastics, flows, cherts, argillites and greywackes. The entire pendant has been classified as part of the Upper Jurassic to Lower Cretaceous Gambier Group. Cenozoic to Mesozoic Coast Plutonic Complex intrusives surround portions of the stratified rocks, creating screens or pendants. These bodies are oriented north westerly throughout the Coast complex. Pliocene to recent Garibaldi Group basaltic dikes and sills intrude both the pendant and plutonic rocks. The occurrence is north of the Indian River shear zone, a discontinuous zone of shearing that trends northwest along the Indian River valley.
Locally, a scattered series of outcrops of sheared felsic metavolcanic rocks of the Gambier Group are mineralized with disseminated pyrite, sphalerite, chalcopyrite and galena. Local silicification is evident. The shear zone strikes north and dips steeply east with a width of 6 metres.
In 1937, a grab sample from the better mineralization in a silicified zone that contained streaks of mixed pyrite, chalcopyrite, sphalerite and galena assayed 212.5 grams per tonne silver, 1.6 per cent copper, 11 per cent lead, 16.5 per cent zinc and 0.68 gram per tonne gold (Minister of Mines Annual Report 1937, page F26).
In 1937, exploration work consisted of open cuts and trenching. During late 1969 and early 1970, Kennedy Silver Mines completed a program of soil sampling and geological mapping on the area as the Agape claims. This work identified a south east- trending area of anomalous copper and zinc values in soils. Later in 1970, Croyden Mines completed a ground electromagnetic survey on the area. In 1978, Placer Development prospected and mapped the area as the Janette claim. In 1982 and 1983, Stackpool Minerals completed programs of rock, silt and soil sampling, geological mapping and ground and airborne electromagnetic surveys on the area. During 2011 through 2016, the area was prospected and sampled as the Sky Pilot Gold property.
