The Wanda occurrence is located at an elevation of approximately 1350 metres on a generally west-facing slope, east of the Wicked River and approximately 4 kilometres south of the south end of Wicked Lake.
The Wicked Lake area is situated on the dome-like, south-plunging nose of the Bernard anticline, bound to the west by the Mount Burden thrust fault and bound to the east by the Nabesche River fault. Hangingwall strata west of the Mount Burden fault include Ordovician to Devonian Road River Group calcareous shale, limestone and siltstone; Ordovician Skoki Formation dolostone, limestone, siltstone and volcanics and Cambro-Ordovician Kechika Group siltstone, shale and limestone. Footwall strata, east of the thrust, include Devonian and Carboniferous Besa River Formation shale and limestone, Middle Devonian Dunedin Formation limestone and dolostone, Lower and Middle Devonian Stone Formation dolostone and sandstone and Silurian and Devonian Muncho-McConnell Formation dolostone and Silurian Nonda Formation dolostone and limestone.
Locally, hydrozincite, smithsonite, sphalerite and galena occur in stratabound, dolomitized and silica-flooded and quartz veined stockworks and solution breccias. The mineralized zones strike northwest and dip approximately 40 degrees southwest.
In 1993, two closely spaced samples (556-G and -H) yielded 7.00 and 8.00 per cent zinc with 0.66 and 0.06 per cent lead, respectively (Assessment Report 23174). Sample 556-G was taken over an area of 3.05 by 6.1 metres, whereas sample 556-H was taken over an area of 1.52 and 3.05 metres. Another sample (556-I), taken to the northwest of the previous samples, yielded 2.00 per cent zinc over 3.05 metres (Assessment Report 23174).
Work History
The area has been explored in conjunction with the nearby ZRR (MINFILE 094B 017) occurrence and a complete regional exploration history can be found there.
In 1993, Noranda Mining and Exploration Inc. completed a program of geological mapping and geochemical (rock, silt and soil) sampling on the area as the Wicked Wanda property.
