The White Moose-B showing is located on the west shore of Taku Arm, south of Buchan Creek.

Quartz veining occurs in Devonian to Middle Triassic amphibolitic gneiss of the Boundary Ranges Metamorphic Suite, near the contact with Early Jurassic granodiorite of the Aishihik Plutonic Suite. Foliations in the schist strike east-southeast and dips moderately south. In this area, these Boundary Range rocks are described as greenstone and greenschist metamorphic rock.

The showing consists of a massive, vuggy, variably hematite stained and mineralized quartz vein in outcrop. Mineralization consists of up to 5 per cent galena and pyrite in blebs. Grab samples averaged trace gold, 71.6 grams per tonne silver, 1.34 per cent lead, and 0.01 per cent copper (Assessment Report 19827).

Work History.

The showings were staked in about 1899 by Young, Johnson, and Grant, officials of the White Pass Railroad. Development work was carried on until 1902 when the property was acquired by a local Atlin syndicate; this group carried on development work until about 1904. In about 1913, the property, consisting of 8 claims (the Pansy, Rose, Buttercup, Calder, Primrose, Daisy, Merry, and Daffodil), was acquired by Messrs. Partridge and Egerton. Development work on the North vein consists of a shallow shaft and a drift adit. On the South vein, two drift adits have been run in a short distance.

In 2011, the showing was reported to comprise a slope-parallel, 30-plus-metre-long trench following a northeast-striking mineralized quartz vein, ending in a sizable 20 by 10 metre dump pile at the valley floor. The uphill (southwest) limit of the trench exposes chlorite schist, intruded by a 1-metre-wide quartz-aplite, all of which have been cut by the sub-vertical, northeast-striking, 30–60-centimetre mineralized quartz vein. Several samples were collected here in 2011, one of which returned 37.7 grams per tonne silver, 0.78 per cent lead, 0.13 per cent copper, and 0.04 per cent zinc. The mineralogy associated with these samples include malachite, galena, chalcopyrite, sphalerite, pyrite, and cerrusite/smithsonite. A second, northeast- to north-striking mineralized quartz vein system was located 50 metres to the southeast of the trenched showing. Here, the crosscutting 20–60-centimetre malachite/azurite-stained quartz vein, with banded galena-chalcopyrite plus/minus pyrite, cuts blue-grey and light-grey banded meta-siltite. The near vertical vein also exploits the main schistose fabric. A series of chip samples across this fabric, parallel to the vertical vein, assayed between 0.3 to 20 grams per tonne silver, up to 0.69 per cent lead, 0.19 to 0.27 per cent copper, and 0.28 to 0.85 per cent zinc (Assessment Report 33152).

All four of the White Moose showings do coincide spatially with significant magnetic breaks, as revealed in the 2011 airborne geophysical survey.
