The Hozameen fault traverses north-northwest separating the low greenschist facies rocks of the Permian-Jurassic Hozameen Complex on the west from Lower-Middle Jurassic Ladner Group sediments to the east. A Late Cretaceous quartz diorite stock intrudes the sediments along the east side of the fault.

The D & J claims are underlain by Hozameen Complex rocks comprised mainly of greenstone, volcanic chert, pelite and limestone. These rocks generally contain fine-grained actinolite, epidote, chlorite and locally prehnite. The limestone is interbedded with the greenstone and commonly forms lenticular beds, up to 30 metres in thickness. The Hozameen rocks are intruded by numerous basic sills and dikes. The bedding strikes fairly uniformly at about 330 degrees and dips between 30 degrees to near vertical towards both the east and west.

Mineralization is comprised mainly of pyrrhotite and chalcopyrite with sphalerite and pyrite. Occasional stringers of arsenopyrite and galena are also present. The sulphides occur as infillings in four major fracture sets with average attitudes of 320 degrees dipping 80 degrees northeast; 350 degrees dipping 75 degrees west; 285 degrees dipping 85 degrees south and a weaker set mineralized predominantly with sphalerite, striking 050 degrees and dipping 80 degrees northwest.

The main showing, at 732 metres elevation, consists of skarn and sulphides in a zone about 6 metres wide striking 340 degrees and dipping steeply to the northeast. Mineralization consists of a mixture of pyrrhotite, arsenopyrite, pyrite and chalcopyrite in a gangue of quartz, epidote, garnet, hornblende and wollastonite. Some native copper was reported in fracture planes. Surrounding the skarn area are 10 centimetre wide quartz veins which host galena, sphalerite, arsenopyrite and pyrrhotite. In 1915, a sample from the main workings analysed 2.74 grams per tonne gold, 64.45 grams per tonne silver, 18 per cent copper and 6 per cent zinc.

In 1948, mineralized stringers hosting mainly pyrrhotite and chalcopyrite, were sampled. A 1.2 metre wide sample analysed 0.34 gram per tonne gold, 41.14 grams per tonne silver, 4.1 per cent copper with traces of nickel, cobalt and zinc (Minister of Mines Annual Report 1948, page 155).
