The Ddam occurrence is located west of Cop Creek, approximately 1.3 kilometres north west of Henry Lake.

The area is underlain by Devonian Sicker Group rocks, predominantly mixed lapilli tuffs and agglomerates of the Nitinat Formation. Included within the tuffs is a siliceous, banded, grey-black aphanitic tuff layer. There are silicified, bleached, altered pyritic zones at stratigraphic contacts.

Mineralization consisting of mainly pyrite with trace amounts of chalcopyrite occur in shear zones with occasional milky grey-white quartz veins ranging from 1 centimetre stockwork veinlets to 10 centimetre wide veins. A barren quartz-epidote-silica phase postdates the milky quartz veins.

In 1986, P. Jones staked the Ddam claims and completed a program of prospecting and geochemical sampling. In 1988, Lacana Ex. completed a program of geological mapping, rock and soil sampling and a ground electromagnetic survey. In 1990, a geophysical program of ground magnetic and electromagnetic surveys was completed. In 1992, the area was explored as the Rook claims. In 2006, the area immediately south, was prospected by Bitterroot Resources Ltd. as the Gap claim.
