The Vav (North) showing is located on Reg Christie Creek, approximately 6.5 kilometres east of the community of Vavenby and 150 kilometres north of Kamloops.
The area is underlain by an east-west–striking, shallow to moderately dipping sequence of Devonian to Mississippian metasedimentary and metavolcanic rocks of the Eagle Bay Formation. Quartzite and chlorite-muscovite-quartz schist are overlain by sericite-quartz phyllite, quartz-chlorite-sericite schist and sericitic quartzite, which are overlain by dark grey phyllite. A thrust fault separates these rocks from calcareous chlorite schist and greenstone to the south.
Disseminated chalcopyrite, pyrite and minor molybdenite occur along foliation planes and on fractures within quartz-chlorite-sericite schists. The mineralized zone trends east-west and measures 800 by 150 metres. Grab samples assayed 0.3 to 0.4 per cent copper (Assessment Report 6933); however, mineralization is irregular and generally low grade.
This area was first staked in 1969 by Nicanex Mines as a result of the discovery of copper mineralization during a regional prospecting program. Subsequent geological, geochemical and geophysical surveys in 1970 outline the copper mineralized zone (Nicanex zone).
In 1975, the ground was restaked by Greenwood Exploration. Greenwood conducted surface geological mapping but allowed the claims to lapse the following year.
Barrier Reef Resources staked the area again in 1977 and carried out geological mapping and geochemical and geophysical surveys in 1978. As a result, a second zone—the AFR showing (MINFILE 082M 152)—was located, which lies parallel to the Nicanex zone. Drilling carried out in 1979 reported 944 parts per million copper over 19.8 metres (Assessment Report 30328).
In 1981, an assessment program entailing geological mapping, very low-frequency electromagnetic surveying, soil sampling, follow-up heavy mineral sampling and rock-chip sampling was carried out on behalf of Kangeld Resources Ltd.
In 1984, one diamond drill hole was completed and intersected a shear zone containing pyrite and pyrrhotite from 113.9 to 144.5 metres. Gold and silver values ranged from 0.19 to 0.88 gram per tonne and 2.5 to 5.6 grams per tonne, respectively (Assessment Report 30328).
In 1988, Goldbank Ventures Ltd. staked the Jar and Mila claims over the known showings. In 1990 and 1991, Goldbank conducted a two-phase program consisting of ground magnetics, MaxMin and induced polarization geophysical surveys, soil sampling and 1794 metres of diamond drilling. Drilling reported 0.34 per cent copper over 11.28 metres (Assessment Report 30328).
In 2005 to 2007, a series of geochemical surveys was completed on the Reg and Mila claims. In 2008, Yellowhead Mining Inc. completed 34 diamond drill holes, totalling 10 440.6 metres.
In 2008, drilling on the North zone assayed
• HC08-62: 1.78 per cent copper over 7.72 metres from 148.33 metres to 156.05 metres;
• HC08-67: 0.65 per cent copper over 11.09 metres from 85.14 metres to 96.23 metres; and
• HC08-73: 0.77 per cent copper over 4.88 metres from 96.46 metres to 101.34 metres (Assessment Report 30320).
In 2011, Christopher O. Naas conducted soil sampling on the Mila and Chuck claims. Results did not suggest any new anomalies or extensions of known anomalies (Assessment Report 32413).
In 2012, Naas conducted geological mapping on the Mila and Chuck mineral claims (Assessment Report 33665).
In 2013, work consisted of silt sampling (11 samples), a 15 line-kilometre, 598-sample gridded soil sampling survey and rock sampling (1 sample). The silt samples were collected to the east of the occurrence, from an area around Chuck Creek, and the rock and soil samples were collected from an area south of Reg Christie Creek that included the Vav (North) and Vav (South; MINFILE 082M 152) occurrences (Assessment Report 34534). From May 2014 to March 2015, a geochemical sampling program was conducted over the northeastern portion of the Mila-Chuck property, including the Vav (North) and Vav (South) occurrences, consisting of a 9-line, 7.625 line-kilometre, 300-sample grid (Assessment Report 35508). In 2015, 372 soil samples were collected from an area south of Chuck Creek and sent for analysis. Most of the samples returned low copper and zinc values; however, a small area of samples in the northern portion of the survey area returned anomalous values. Follow-up work was recommended (Assessment Report 36049).
