The Val 5 occurrence is located about 37 kilometres south of the community of Germansen Landing. The Valleau property claims (ca. 2012) covers this showing as well as the Valley Girl (093N 111) located 7 kilometres southeast.
The Val 5 showing occurs within a northwest trending Middle Triassic to Late Jurassic sequence of Takla Group rocks consisting schistose siltstones, argillites, and lithic tuffs interbedded with andesitic, augite porphyry flows. Narrow quartz porphyry and diorite dikes cut this sequence.
Three main styles of mineralization were observed by Placer Dome in the Val 5 area in 1991: 1) narrow milky quartz, minor carbonate veins with pyrite, chalcopyrite and local arsenopyrite, 2) quartz-carbonate cemented breccias with local blebby and veinlet pyrite, and 3) disseminated pyrite and pyrrhotite in andesitic flows and sediments.
Eighteen rock samples were taken from this area. The quartz veins (style 1) locally produced anomalous gold with copper values, the best being 0.8 gram per tonne gold with 0.15 per cent copper and 24 grams per tonne silver (Assessment Report 22414). A number of the samples had highly anomalous arsenic (to 1337 parts per million) associated with the gold and copper. The other styles of mineralization did not produce any significant gold or copper values.
To the north, on the Val 3 claim, Placer Dome Inc. identified variably brecciated, silicified and carbonatized volcanic, sedimentary and intrusive (dioritic) rocks with quartz-carbonate veining and stockworks with disseminated pyrite, reported to possibly represent the silicified roof zone of a buried (dioritic?) intrusive body. Some of the quartz veining is reported to have epithermal characteristics. In 1991, 14 float and subcrop samples taken from the western Val 3 area are reported to have yielded consistent gold values ranging from 0.08 to 0.12 gram per tonne (Assessment Report 22414).
On the Val 4 claim, located approximately 3.6 kilometres to the east-northeast of the Val 5 occurrence, a silicified intrusive in contact with biotite hornfels hosting disseminated molybdenite is reported. In 1991, a rock sample (4766) assayed 0.119 per cent molybdenum (Assessment Report 22414).
Work History
In 1989, Placer Dome Inc. conducted a program of prospecting, reconnaissance geological mapping, soil sampling and stream sediment sampling on the Val property (Assessment Report 19859). In 1990, Placer Dome conducted a follow-up program on the southwestern part of the property. This was a follow-up program investigating anomalous gold and copper values from drainages on the Val 7 claim and consisted of grid coverage, geological mapping, soil, and silt sampling. In 1991, Placer Dome personnel conducted a short exploration program on the Valleau Creek property consisting of geological and follow up geochemical surveys (Assessment Report 22414). During this program, 58 rock, 5 silt, and 120 soils samples were collected. The 1990 stream sediment sampling identified very fine-grained placer gold along Chickadee Creek, located approximately 3.5 kilometres to the south-southwest. Most of the gold grains were reported to be angular in shape, suggesting a short transport distance.
In 2005, Serengeti Resources Inc. carried out a 530-kilometre airborne magnetic-radiometric survey and collected 12 rock samples on their Valleau and Germansen properties, which cover the Valley Girl (093N 111), Valleau Creek (093N 053), Val 5 (093N 240) and KC (093N 006) occurrences. The airborne survey identified eight magnetic anomalies.
In 2007, Serengeti Resources undertook magnetic (20.6 kilometres) and induced polarization (26.9 kilometres) surveying on the Valleau property.
During 2010 through 2012, Serengeti Resources Inc. completed programs soil and rock sampling on the area. This work identified a zone of anomalous copper ± gold-in-soil to the south associated with an induced polarization anomaly south of the Val 5 occurrence.
During 2005 through 2014, Redton Resources Inc. (later Kiska Metals Corp.) completed programs of prospecting, geochemical (rock, silt, and soil) sampling, geological mapping and ground and airborne geophysical surveys on the regionally extensive Redton property, located immediately to the east. Refer to the North Kwanika (MINFILE 093N 077) occurrence for a complete summary of this work.
