The Vav (South) occurrence is located on Reg Christie Creek, approximately 6 kilometres east of the community of Vavenby and 150 kilometres north of Kamloops.

An east-west–striking, shallow to moderately dipping sequence of metasediments and metavolcanics of the Devonian to Mississippian Eagle Bay Formation underlies the area. Quartzite and chlorite-muscovite-quartz schist are overlain by sericite-quartz phyllite, quartz-chlorite-sericite schist and sericite quartzite. These are overlain by dark grey phyllite, which is separated by a thrust fault, with calcareous chlorite schist and greenstone to the south.

The AFR zone trends west, plunges approximately 20 degrees and consists of several mineralized outcrops in an area of 1000 by 150 metres. Disseminated chalcopyrite, pyrite and minor molybdenite occur in silvery phyllite and slightly calcareous quartz-chlorite-sericite schist.

A 1-metre chip sample assayed 0.109 per cent copper (Assessment Report 13557), and a percussion hole drilled in the west part of the zone intersected 0.094 per cent copper over 19.8 metres (Assessment Report 7119). A hole 170 metres to the west intersected 0.036 per cent copper over 39.6 metres and 0.004 per cent molybdenum over 12.2 metres (Assessment Report 7119).

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, known as the Nicanex zone (MINFILE 082M 151).

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 was carried out in 1979.

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.

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.

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 Southern Zone assayed

• HC07-43: 1.06 per cent copper over 3.46 metres from 168.06 metres to 171.52 metres;

• HC07-46: 0.71 per cent copper over 10.85 metres from 35.04 metres to 45.89 metres; and

• HC08-58: 0.95 per cent copper over 7.44 metres from 81.49 metres to 88.93 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; MINFILE 082M 151) and Vav (South) 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).
