The White Moose-North 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 general, the Boundary Range metamorphic rocks are described as greenstone and greenschist metamorphic rock.
An adit on the lakeshore was driven on the White Moose North vein containing chalcopyrite, bornite, galena, and minor sphalerite and malachite (and possibly tetrahedrite). The vein strikes 140 degrees and dips 40 to 60 degrees northeast. The massive, white, locally vuggy quartz vein is 0.45 to 1.2 metres wide. Blocks of quartz containing up to 8 per cent sulphides occur in the dump. A mineralized vein up to 12 centimetres in width also occurs above the workings.
South of the adit, a vein, 17 centimetres wide with 5 per cent sulphides, assayed trace gold, 0.34 grams per tonne silver, 0.13 per cent lead, 0.09 per cent zinc, and 0.09 per cent copper (Assessment Report 8384).
Work History
This property is located on the west shore of Tagish Lake, the claims extending south from Buchan Creek. 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.
The 2011 visit to the White Moose-North showing by Blue Gold Mining Inc. consisted of a helicopter assisted grab sampling of the dump that intersects the lake shore. Sample JBTIR094 comprised quartz vein material from the dump, with small, massive sulphide lenses (chalcopyrite greater than galena) that assayed 14 grams per tonne silver, 0.09 per cent lead, 0.5 per cent copper and 0.13 per cent zinc (Assessment Report 33152). Reconnaissance mapping between the shaft and north showings encountered significant feldspar porphyry outcrop, indicative of significant igneous activity as a potential heat source for mineralization and/or a contributing factor to structural preparation.
All four of the White Moose showings do coincide spatially with significant magnetic breaks as revealed in the 2011 airborne geophysical survey.
