The Comet showing is located on the south side of Four Mile Mountain, 8 kilometres east of Hazelton. The property has been explored by a 45-metre long adit at the 370 metre level, as well as two shorter adits and several small trenches.
The property is underlain by intensely altered tuff and sandstone of the Middle Jurassic to Lower Cretaceous Bowser Lake Group, which is intruded by a small (1500 metres in diameter) stock of coarse grained grey granodiorite of the Eocene Babine Intrusions. Potassium/argon dating of biotite in the stock indicates an age of 55 million years (Geological Survey of Canada Open File 2322).
The grey granodiorite and, to a lesser extent, the sedimentary rocks, are host to a number of narrow sulphide-bearing quartz veins on the property. The veins occupy fracture zones and contain variable amounts of jamesonite, sphalerite, galena and pyrite. Some veins are rich in siderite. The veins strike between 345 degrees and 080 degrees, dip 15 to 60 degrees east or southeast and range up to 25 centimetres in thickness.
One 25-centimetre sample assayed 0.3 gram per tonne gold, 297.6 grams per tonne silver, 1.22 per cent lead, 2.29 per cent zinc and 0.47 per cent antimony (Geological Survey of Canada Memoir 223, page 40).
In 1983, three samples (F-4-1 to F-4-3) yielded from 5.61 to 12.6 per cent lead, 0.52 to 1.49 per cent zinc and 93.0 to 166.6 grams per tonne silver (Thomson, G.R. (2009-06-09): Technical Report on the American Boy - Mohawk Claim Group).
