The WL 4 occurrence is located on a northeast-facing slope, southwest of the north end of Wicked Lake and approximately 110 kilometres north of the town of MacKenzie.
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.
Limonitic gossans, along the base of the Mount Burden thrust fault hosted within Skoki dolostone, compose the WL 32 occurrence. The gossans are associated with limonitic pyritic mats overlying massive pyrite/marcasite pods, veins and disseminations, are up to 900 metres in length and 2 to 3 metres thick, locally.
In 1972, samples yielded values of up to 0.545 per cent lead and 0.081 per cent copper (Assessment Report 4141).
In 1974, sampling of trench 2-3 yielded 0.100 per cent copper and 0.114 per cent lead over 0.6 metre, whereas a sample from trench 2-5 yielded 8.8 grams per tonne silver over an area of 0.6 by 0.9 metre (Assessment Report 5246).
Work History
In 1972, Ecstall Mining Corp. completed a program of prospecting, geological mapping and geochemical (rock and soil) sampling on the area as the WL 1-32 claims of the Wicked property. In 1974, a program of prospecting, geological mapping, trenching and geochemical (rock, silt and soil) sampling was completed on the WL and ZRR claim groups.
In 1980, Rio Tinto Exploration Canada Inc. conducted a program of prospecting geological mapping and geochemical (silt and soil) sampling on the area as the Evil 1-2 claims.
