This showing outcrops along the west side of Siwash Creek, 9 to 10 kilometres north of the creek's confluence with Hayes Creek.

The June occurrence is hosted in coarse to medium-grained quartz monzonite with pink feldspar, of the Middle Jurassic Osprey Lake batholith. The mineralized monzonite is occasionally brecciated and tends to exhibit pale green talc-chlorite-epidote alteration in zones of disseminated sulphides.

Mineralization consists primarily of disseminated galena, chalcopyrite and pyrite, contained in three northwest-trending zones, 300 to 380 metres long and 20 to 80 metres wide. The zones are arranged in an en echelon manner, over a northeast distance of 600 metres. Similar mineralization is hosted in the occasional quartz vein. A sample of a quartz vein containing disseminated bornite, pyrite, galena and chalcopyrite assayed 309 grams per tonne silver, 2.80 per cent lead, 0.072 per cent zinc and 0.32 per cent copper (Assessment Report 3282, page 8, sample Paco No. 2). A chip sample of a quartz (?) vein with pyrite, chalcopyrite, tetrahedrite, galena and sphalerite, taken 90 metres to the north, assayed 1145 grams per tonne silver, 8.71 per cent lead, 0.27 per cent zinc and 0.06 per cent copper over 0.6 metre (Sample Paco No. 1). Gold values of up to 10 grams per tonne over 2 metres are reported from surface workings (Assessment Report 20329, page 9). The mineralization comprising this showing is thought to represent the marginal phase of a porphyry hydrothermal system centred to the north, possibly associated with a body of quartz feldspar porphyry of the early Tertiary Otter intrusions (Assessment Report 15863).

In 2011, a grab sample (11KRP105) assayed 0.173 gram per tonne gold, 472 grams per tonne silver, 3.84 per cent copper, 3.31 per cent lead and 2.75 per cent zinc (Moroney, D.M. (2012-06-04): Technical Report on the Siwash Creek and River Wild Properties).

Work History

The area has been explored in conjunction with the nearby Snowstorm (MINFILE 092HNE032) occurrence and completed exploration history can be found there.

Various operators have conducted soil geochemical and geophysical surveys over this showing, beginning with Diana Explorations Ltd. in 1971. Other operators included Agur Logging Company Ltd. (1978), Brenda Mines Ltd. (1979-1980) and Westron Venture Ltd. (1986). Six holes totalling 141 metres were drilled between 1973 and 1978 by Diana Explorations and Agur Logging.
