The Outland Silver Bar occurrence lies on the west side of the Salmon Glacier, north of Mount Bayard. Host rocks are banded, dark, quartzitic siltstones and greywackes, which are bounded by andesitic tuffs of the Lower Jurassic Unuk River Formation (Hazelton Group). The area lies within the northwest extremity of the Eocene Portland Canal dyke swarm, which consists of diorite to granodiorite dykes. Hornblende granodiorite of the Texas Creek Batholith lies to the west and south.

The sedimentary rocks are marked by breccia and narrow mylonite zones and by complex, small scale, isoclinal folding. Quartz veins and mineralization cut altered porphyritic hornblende diorite and quartz diorite dykes and are subsequently cut by dark green andesitic dykes.

Several mineralized quartz veins and gossans occur on the property. The main vein or "Johnnies" vein, which trends north- northeast, dips 70 degrees east, and has been explored by two adits. The vein has a width of 1.3 metres, a mineralized length of 30 metres and occurs in brecciated altered siltstones. It has been cut by small dioritic dykes. Other smaller veins are found in the older dykes but generally show little extension into the siltstones. The veins consist of quartz with scattered galena, sphalerite, tetra- hedrite and pyrite with minor chalcopyrite. These veins trend north to northeast and dip east. A 2.0 metre channel sample from the Johnnies vein assayed 166 grams per tonne silver, 1.4 grams per tonne gold, 2.17 per cent copper, and 2.28 per cent lead (Assessment Report 8909).

About 100 metres to the southeast, an east-northeast trending vein cuts silicified argillite. It is less than 50 centimetres wide and a 0.3 metre sample of vein material assayed 936 grams per tonne silver, 1.4 grams per tonne gold, 0.53 per cent copper, 7.02 per cent lead, and 7.68 per cent zinc (Assessment Report 375).

Lenses of sulphide mineralization, that have been referred to as being replacement-type, occur in pyrite-rich siltstones and mudstones, 500 metres east-northeast of Johnnies vein. These mineralized zones, which trend east-northeast and dip steeply north, contain pyrite, pyrrhotite, arsenopyrite, and scattered chalcopyrite, galena, tetrahedrite, argentite, sphalerite and an unidentified tungsten mineral. A 10 metre sample from and adit assayed 95.3 grams per tonne silver, 0.3 grams per tonne gold, 0.23 per cent lead, and 0.19 per cent zinc (Assessment Report 8909). Twenty-nine samples were assayed for tungsten oxide (WO3) and they contained between 0.01 to 0.06 per cent tungsten oxide (Assessment Report 8909).

From 1926 to 1929, 4 tonnes of ore produced 3328 grams of silver, 13 kilograms of copper, and 507 kilograms of lead.
