The Kingfisher (Central) occurrence is located on a ridge separating Kingfisher and Danforth creeks, approximately 4 kilometres north of their junction.
The area lies within the Precambrian- Paleozoic(?) Shuswap Metamorphic Complex, a belt of high- grade metamorphic rocks. Rocks on the property comprise a heterogeneous package of granitoid gneiss, augen gneiss, sillimanite-bearing schist and prominent marble and quartzite layers.
The rocks on the Kingfisher property have been divided into six metamorphic units and two intrusive units. The sequence of metamorphic units probably represents an originally conformable package of sedimentary rocks (Geology in British Columbia 1975).
Unit 6 is the structurally lowest unit and consists dominantly of medium to coarse- grained garnet biotite gneiss that is intruded by many granite-pegmatite sills and dikes. Some white quartzite, marble and rare calc-silicate gneiss layers occur in unit 6. Unit 5 consists of fairly pure marble interlayered with quartzite. Included in the quartzite are some garnet biotite gneiss layers, and along the quartzite-marble contacts, coarse- grained calc-silicate gneiss. The more impure quartzite of unit 5 (that containing diopside and/or feldspar) may be mineralized with sulphides. Unit 4 is a heterogeneous unit comprised predominantly of calc-silicate gneiss, but includes rusty weathering to clean white marble, garnet biotite gneiss, minor quartzite and minor amphibolite. The rocks of unit 4 host sulphide mineralization in the Central zone, which forms the Kingfisher deposit. Unit 3 is a massive white marble up to several hundred metres thick. Included in the marble are a number of discontinuous layers of garnet biotite gneiss and hornblende gneiss. The most significant mineralization in the Central zone is contained within unit 3. Unit 2 consists of rusty weathering garnet-biotite- sillimanite gneiss with minor amounts of associated calc-silicate gneiss. Granite-pegmatite bodies, up to several hundred metres in diameter, commonly intrude unit 2. Unit 1 consists of hornblende gneiss, garnet biotite gneiss and some calc-silicate gneiss.
Units 1 to 6 are intruded by numerous granite-pegmatite and aplite dikes, sills and irregular stock-like bodies. These range in size from small discontinuous sills a few metres in length to almost equidimensional, stock-like intrusions several hundred metres in diameter. A number of north- trending quartz feldspar porphyry dikes also cut across the layered rocks and are generally 5 to 10 metres in width.
In summary, the succession of metasedimentary rocks in the Kingfisher area includes biotite gneiss, interlayered quartzite and marble, and calc-silicate gneiss overlain by a thick marble layer (unit 3). These units are in turn overlain by biotite gneiss and minor associated calc-silicate gneiss, and then calcareous hornblende gneiss and amphibolite of unit 1. The rocks have been subjected to high- grade regional metamorphism; aluminous gneisses contain sillimanite and occasionally kyanite. The rocks are indicative of upper amphibolite and/or granulite facies of metamorphism (Geology in British Columbia 1975).
The structure in the area is dominated by four northwest- trending faults. These separate the layered rocks into five distinct blocks. The apparent movement of the faults is right-lateral strike-slip with displacement ranging from approximately 100 to 700 metres. The faults cut across an earlier mineral foliation which strikes north-northeast and dips at varying angles to the southeast. This foliation is everywhere parallel or almost parallel with layering. Mineral lineations contained within the foliation plunge to the southwest. Two types of mesoscopic folds are common. The first is typically tight to isoclinal and plunges to the southwest, parallel to the mineral lineations. The second type is more open and has a more variable attitude, although generally it also plunges to the southwest.
Five or six separate areas of mineralization have been identified in the Central zone, hosted in marble of unit 3 and calc-silicate and quartzite of units 4 and 5 over a distance of approximately 720 metres. Mineralization in marbles consists of dark, medium-grained sphalerite, with varying amounts of pyrrhotite and minor pyrite disseminated through a medium to coarse- grained white calcite matrix. Galena is also common, though much finer grained and more widely scattered. The sulphide concentration varies considerably across a mineralized zone, commonly producing a crude layering.
Mineralized quartzites almost invariably contain calcareous minerals in accessory amounts. Dark sphalerite with pyrrhotite is concentrated generally in thin layers. Galena is more common in quartzites than in the marbles, although it is always subsidiary to sphalerite. The sulphide concentration varies from widely scattered individual grains to almost massive intergrowths.
Mineralization in calc-silicate gneisses shows gradational features between that in marble and that in quartzite. Sphalerite, pyrrhotite, pyrite ± galena may be evenly distributed through a coarse- grained calcite-diopside rock or may tend to concentrate in layers in a more quartz-rich rock. In general, mineralized sections in quartzites are of lower grade but are more continuous along strike with the layering than those in marble. Discontinuous high-grade pods are common in the marbles.
In 1973, diamond drilling (hole 73-3) yielded intercepts up to 1.36 per cent lead and 3.47 per cent zinc over 24.3 metres, with a true width of 9.9 metres, while the following year, drill hole 74-8 intercepted 1.95 per cent lead and 3.70 per cent zinc over 6 metres, with a true width of 4.5 metres (Assessment Report 4933).
In 2001, six rock samples (KF 01 to 06) from approximately 3.5 tonnes of stockpiled crushed rock yielded an average of 5.44 per cent lead, 9.16 per cent lead and 3.6 grams per tonne silver, while four dump samples (KF 07 to 10) yielded an average of 0.277 per cent lead and 7.61 per cent zinc (Assessment Report 26730). A composite chip sample (CM7-1) assayed 9.43 per cent lead, 11.60 per cent zinc and 6.12 grams per tonne silver over 1.5 metres (Assessment Report 33197).
In 1974, indicated reserves on the Kingfisher property were reported as 1.67 million tonnes grading 0.58 per cent lead and 2.6 per cent zinc (Statement of Material Facts 25/10/74, Colby Mining Limited).
In 1966, 4 tonnes of ore yielded 5.008 kilograms of silver, 450 kilograms of lead and 166 kilograms of zinc (Assessment Report 33197). In 1976, 12 tonnes of ore was shipped from the Central zone and yielded 187 grams of silver, 1157 kilograms of lead and 830 kilograms of zinc (Assessment Report 33197).
In 1964, Sheep Creek Mines completed a program of trenching, geological mapping and six diamond drill holes, 192.6 totalling metres. Later, in 1964, Cominco completed a program of geological mapping and a 50.3 line-kilometre ground magnetic survey on the area as the Bright Star and Kingfisher claims. In 1969, Bright Star Trio Mining completed a program of geological mapping and a 25.7 line-kilometre ground magnetic survey on the area. During 1973 through 1977, Colby Mines completed programs of geological mapping, a ground magnetometer survey, rock sampling and 36 diamond drill holes, totalling 2278.0 metres, on the area as the Black Jack property. Later in 1977, Union Oil Company of Canada drilled one hole, totalling 104.0 metres. No assays were reported for the last 12 diamond drill holes completed in 1977. In 2001, Discovery Consultants rock sampled the area. In 2012, Inexco Mining completed a program of prospecting, rock sampling and a 205.3 line-kilometre airborne electromagnetic survey on the area.
