The White Moose-Shaft showing, located on the west side of Taku Arm, is 600 metres south of the White Moose-North adit (104M 009).
The area is underlain by the Devonian to Middle Triassic greenstone and greenschist of the Boundary Ranges Metamorphic Suite, cut by a northwest trending rhyolitic dike. Contact with Early Jurassic granodiorite of the Aishihik Plutonic Suite occurs just south.
The showing comprises two shafts, 35 metres apart. A 40-centimetre-wide quartz vein on the side of one of the shafts appears to follow the rhyolite-schist contact.
A 27-centimetre-wide chip sample across the vein contained 5 to 10 per cent fine-grained galena, 4 per cent pyrite, and minor chalcopyrite and malachite. This sample assayed 2.06 grams per tonne gold, 27.43 grams per tonne silver, 2.45 per cent lead, and 0.01 per cent copper (Assessment Report 8384).
At Occurrence D, about 300 metres to the southeast, a 60-metre-long trench and collapsed adit occur. No vein was exposed in outcrop, but quartz float with minor malachite, pyrite, and galena was observed (Assessment Report 8384).
Work History
The White Moose 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, Blue Gold Mining Inc described the White Moose Shaft showing as consisting of two 3 by 4 metre shafts (now caved in pits), spaced 42 metres apart, along strike of the main north-northwest schistose foliation. Mineralized quartz vein material, in situ and from the shaft waste piles, have similar mineralization styles as material from the White Moose B showing (104B 072). A total of 2 grab samples (N-shaft: BRTIR008; and S-shaft: JBTIR093) were collected and yielded the following values respectively: 19.7 and 66 grams per tonne silver; 0.8 and 4.92 per cent lead; 0.25 per cent and 0.0063 per cent copper; and 0.34 and 2.13 per cent zinc (Assessment Report 33152). Relative to the Moose-B trench area, the main difference is that the Shaft quartz vein is conformable within the foliation of the host chlorite schist. Visible in the southern shaft is a micro-granite (or aplite) sill paralleling the main mineralized quartz vein, with very rusty and sericite altered chlorite schist hostrock separating the two intruded units. East of the southern shaft, feldspar porphyry and meta-siltite outcrops are notable, both within 25 metres of the shaft.
In 2013, a single day field program conducted by Eagle Plains produced 92 soil samples and four rock samples for analysis. Samples were collected at, or near, the White Moose-Shaft (104M 012) or Buchan (104M 036). Soil samples highlighted a potential parallel vein system to the east of the White Moose trend, extending the historic anomaly consisting of bismuth, silver, copper, zinc, lead, and to a lesser extent, gold (Assessment Report 34573). Soil sampling in the vicinity of the White Moose-Shaft occurrence returned interesting results and expanded on the results from sampling in 2007. The mineralization at the showing itself seems to be limited as sampling over the occurrence only produced a single point anomaly for lead, copper, silver, zinc, and bismuth.
All four of the White Moose showings (104B 009, 010, 012, and 072) are reported to coincide spatially with significant magnetic breaks as revealed in the 2011 airborne geophysical survey that covered all of the Titan property.
Refer to Titan (104M 089) for further details of the Titan property, of which the White Moose showings are part of.
