The Dynamiter showing is located approximately 4.8 kilometres south of Woodcock on the east side of the Skeena River. The area was investigated in 1931 when the group of claims was owned by W. Minther, of Cedarvale.

The area is underlain by sediments of the Middle Jurassic to Upper Cretaceous Bowser Lake Group, which are intruded by Tertiary (and possibly younger) granitic Coast Plutonic Complex rocks.

Mineralization occurs on the bedding planes of argillite near alaskite tongues. Bedding strikes approximately east and dips 45 degrees north. Mineralization consists of pyrrhotite, arsenopyrite, pyrite and a small amount of stibnite.

Historic workings are located between 373 and 396 metres elevation. At 373 metres elevation and 1.5 metres above a lake, a tunnel was run 20 metres at 295 degrees azimuth. At 385 metres elevation and about 46 metres west of the tunnel, a shaft was sunk to a depth of 6.5 metres following the westerly continuation of the mineralization that was intersected in the tunnel. The shaft exposes 2.3 metres of iron-stained argillite heavily mineralized with arsenopyrite. A brecciated zone 1.1 metres wide in the hangingwall exhibits the best mineralization. A sample from this zone across the width assayed trace gold, 12.3 grams per tonne silver and 0.5 per cent antimony (Minister of Mines Annual Report 1931, page A72). Similar mineralization is exposed in an opencut 60 metres to the west of, and 10 metres higher in elevation above the shaft.
