The area is underlain by the Lower Cambrian part of the Eagle Bay Formation consisting of siliceous and graphitic phyllites, phyllitic limestone and greenschist. The metavolcanics and meta- sediments generally strike northeast and dip 10 to 40 degrees north- west. The rocks are cut by Late Cretaceous or Early Tertiary quartz- feldspar porphyry and mafic dykes with northerly trends.

The King Tut occurrence lies about 900 metres northeast of Lucky Coon (082M 012). The lens strikes 55 degrees intermittently for 1200 metres. Mineralization consists of galena, pyrite and sphalerite across a one metre siliceous band within dark phyllites. A 60 centimetre sample assayed 295 grams per tonne silver, 7.6 per cent lead and 21.5 per cent zinc.

One hundred and fifty metres to the northeast a 60 to 75 centi- metre silicified band within chloritic schist contains pyrite, arseno- pyite, galena and sphalerite. A 90 centimetre sample assayed 2.7 grams per tonne gold, 1118 grams per tonne silver, 28.8 per cent lead and 8.4 per cent zinc.
