Work History
Discovered during a regional reconnaissance survey of potential limestone sites completed in 1995, by 14844 Yukon Inc (aka Yukon Lime Inc) which staked Mac cl 1-4 (YB66288) in Oct/95. The company added Jeanie cl 1-12 in May/96. Subsequently the claims were optioned to 145976 Yukon Inc which surveyed the claims in May/97 and blast trenched, sampled and drilled 7 reverse circulation holes ( 193.5 m) in Jul/97. As part of their exploration program, 145976 Yukon Inc staked BDM cl 1-4 (YB97656) in May/97, Rob cl 1-3 (YB97768) in Jun/97 and Rich cl 1-3 (YC08024) in Aug/97.
Capsule Geology
The occurrence is located at the northern end of the Stikinia Terrane, the largest terrane underlying the Intermontane region of the Cordillera. Stikinia consists of an Upper Paleozoic volcanic arc basement upon which the Lewes River volcanic arc was built during the Middle and Late Triassic. Detritus from the uplifted arc accumulated up to seven kilometers of strata in the adjacent marginal basin through Middle Jurassic time. This basin, known as the Whitehorse Trough, is composed of Late Triassic volcanic rich detritus and carbonate of the Lewes River Group and Jurassic intrusive-rich clastics of the Laberge Group.
The occurrence is located on the side of a prominent hill and is underlain by a resistant, white weathering, limestone tentatively assigned to the Upper Triassic Hancock Member of the Lewes River Group. The limestone is locally interbedded with fine grained clastic and calcareous siltstone. The 7 reverse circulation drill holes were all collared on the Mac claims and tested the calcium carbonate (CaCO3) content of the limestone units. Hole RC-97-03 intersected 16.8 m of 95.23% CaCO3. The other holes all intersected lower grades. The drill program demonstrated that there is a strong correlation between low silica content and high calcium carbonate.
