Work History
Staked as Moly cl 1-56 (YA65451) in May/83 by Piedmont Exploration Ltd and Last Frontier Enterprises Ltd, which staked Sappo cl 1-16 (YA88192) to the southwest and northeast in Oct/86. L. Mollot tied on MM cl 1-18 (YA88208) to the northwest in Oct/86 and carried out geological mapping, prospecting and geochemical sampling in 1987 and 1988.
The Ney cl 1-40 (YB4742) were staked to the north of the Sappo claims in Feb/88 by Golden Rum Resources Ltd, which immediately transferred them to J. Bergvinson. In Aug/88 Bergvinson optioned the claims to Layfield Resources Inc, which carried out rock, stream sediment and contour geochemical soil sampling and a single line of magnetometer surveying later in 1988. The Moly claims were transferred to Last Frontier Enterprises Ltd in May/88 and were subsequently returned to Piedmont Exploration Ltd in Jul/96.
Restaked as Rock cl 1-6 (YB94769) in Oct/96 by Dredge Master Gold Ltd, which staked Babe cl 1-4 (YB94775) at the same time to surround the two remaining Moly claims on three sides. Dredge Master (L. Turner) staked Key cl 1-26 (YC04629) contiguously north of the Babe claims in Sep/97. In Sep/98, Z. Fras restaked the Babe claims as Zoro cl 1-4 (YC12544).
Restaked as Erni cl 1-80 (YC07271) in Jun/98 by J.P. Ross adjoined the Key claims on the southwest side. In Aug/98 Kennecott Cananda Exploration Inc staked Sixty cl 1-143 (YC12289) to surround the Key claims on the other three sides, forming a contiguous claim block with other claim groups they had staked or optioned to the north over the previous year (Minfile Occurrences #116C 019, 020, 082 and 146). In Apr/99 Kennecott staked Sixty cl 144-257 (YC13419) at the southeast end of their assembled land package and carried out prospecting, geochemical sampling and airborne geophysical surveying over the claim block before dropping all its options in the area the following year.
Ross carried out prospecting and geochemical rock, silt and soil sampling of the Erni claims in 1999 and 2000.
Capsule Geology
A south-dipping thrust fault is inferred to cross the area, separating Late Devonian (?) to mid-Mississippian Nasina assemblage schist and amphibolite (units DMs and DMasc) in the hangingwall from rusty-weathering quartz-muscovite schist of the Permian Klondike Schist assemblage (unit Psqm) in the footwall. A thrust-fault-bounded lense of undated serpentinite (unit Pu), assigned by Mortensen (1996) to the Slide Mountain Terrane (Dawson/Clinton Creek assemblage), occurs along the fault to the east of the occurrence. A vuggy quartz carbonate vein containing no visible sulphides outcrops in the hangingwall of the fault. It is 1 m wide, strikes 140¿ and dips 38¿S. A specimen from the vein assayed 992.5 g/t Ag with 310 ppb Au and 1 140 ppm Cu.
Ross¿s sampling in 1999 and 2000 was of a rcconnaissance nature and was concentrated on the northeastern half of the Erni claims group. Soil sampling returned peak values of 125 ppb Au and 226 ppm As. Extensive silt sampling of Bedrock Creek, which parallels the northeastern boundary of the claim block, produced a number of significantly anomalous results with peak values of 447 ppb Au and 167 ppm As. Comparison of results of -80 mesh vs -200 mesh material clearly showed that analysis of the smaller -200 mesh size fraction returned results that were 3 times stronger than the larger -80 mesh size fraction.
