The Doer showing is located 1.6 kilometres south of the mouth of the Sarita River on the northwest facing slope of Poett Heights. The Sarita River showings (092C 032) are just to the east. In the Sarita River area, exploration for iron is recorded in 1895 and activity apparently continued until 1922 during which time an adit was developed on the Numukamis Reserve No. 1.

The area is underlain by carbonate rocks of the Upper Triassic Quatsino Formation, Vancouver Group and volcanic rocks of the Lower Jurassic Bonanaza Group. These have been intruded by Early to Middle Jurassic Island Plutonic Suite granitic rocks. The structural trend is northwest with easterly dips.

Mineralization comprises massive magnetite, pyrrhotite, pyrite, arsenopyrite, chalcopyrite, sphalerite, malachite, azurite and possibly tetrahedrite with associated propylitic alteration consisting of epidote, chlorite and calcite. Mineralization occurs in skarns within Quatsino limestone and Bonanza tuffs related to the intrusive event and near the contact.

The highest assay result was from a sample (#8286) taken from the northwest corner of the Doer 3 claim which assayed 0.430 grams per tonne gold, 18 grams per tonne silver, 0.05 percent zinc, 0.002 percent lead and 1.35 per cent copper (Assessment Report 5472).
