Work History

Staked as Cabin cl 1-123 (YA63717) and Old cl 1-62 (YA75930) in Aug/81 by Union Carbide Canada Ltd, which performed mapping and geochem sampling in 1981 and 1982 and an aeromagnetic survey in 1982.
In Apr/95 B. Lueck staked HR cl 1-64 (YB44117) just east of the showing, and subsequently optioned them to Yukon Gold Corp. In the summer of 1995, the company carried out an exploration program consisting of geological mapping, prospecting, rock chip and soil sampling.
In Jul/96 Yukon Gold staked Ben cl 1-64 (YB65677) overtop of the expired HR claims and conducted further exploration work. In Jun/97 the Ben claims were optioned to Cyprus Canada Inc, which carried out a reconnaissance sampling program later in the summer.
Eagle Plains Resources Ltd and Miner River Resources Ltd restaked the occurrence as Cabin cl 1-6 (YB65391) in Jun/96 and carried out a reconnaissance exploration program later in the year.

Capsule Geology

The area is located in the Selwyn Basin and was first staked to cover a small Tombstone Suite Pluton. The Old Cabin Pluton is about 2.5 km in diameter . Cecile (1998) described it as a Upper Cretaceous, biotite, granite to quartz monzonite pluton. It intrudes a Upper Proterozoic to Ordovician sequence of sedimentary and basic and volcano-clastic rocks. The sedimentary sequence consists of mainly shales, argillites, quartzites, cherts and conglomerates. The volcanic rocks consist of basic volcaniclastics, breccias, lappili tuffs, flows, sills and dykes and occurs as a thick succession and tongues in the under and overlying sedimentary rocks.
The contact between the pluton and sedimentary rocks is quite sharp with the zone generally measuring only several metres wide. Fine grained clastics surrounding the pluton have been metamorphosed to a dark fine-grained, magnetite bearing hornfel that is defined by its strong magnetic signature. A 100 m by 50 m skarn zone was noted on the western edge of the pluton.
Two types of mineralization have been recognized. The first comprises 1 cm wide quartz or quartz-calcite veins containing arsenopyrite, pyrite, pyrrhotite and molybdenum that cut the granodiorite and hornfelsed sedimentary rocks. These veins are common throughout the area but have no significant width or stike length. The other is a skarn-style consisting mainly of pyrrhotite and magnetite in calcite rich matrix and massive pyrrhotite. Minor amounts of pyrite, chalcopyrite and smithsonite have been observed in float material. Textures of the skarn vary from banded, to brecciated to fine grained homogeneous.
Union Carbide Exploration noted arsenopyrite-bearing veins with minor pyrite, chalcopyrite and argentiferous galena at six locations within the hornfelsed sequence of sedimentary rocks. The individual veins range from 1 to 15 cm wide, and produced assays up to 22.5 g/t Au. Molybdenite-bearing quartz veins were also found cutting the stock.
Yukon Gold explored for and targeted their exploration efforts towards finding Fort Knox style mineralization within the intrusion. Soil sampling and chip sampling outline a large gold and arsenic anomaly on the HR claims. Follow up work carried on the restaked Ben claims returned gold values ranging up to 1.35 g/t Au in hornfelsed sediments.
Cyprus Canada collected 11 rock samples from the east and west contact zones. Two samples returned gold values of 5 396 ppb Au and 4 942 ppb Au. Both samples were collected from the west contact zone. The first sample was taken from quartz vein float located on a ridge top and contained 1 - 2% disseminated galena. The second was collected from a 0.3 m wide quartz-chalcedonic vein mineralized with a silvery sulphide (arsenopyrite?) hosted in hornfelsed black chert horizon below an old trench. A zone of bleaching and clay alteration was noted. These two samples also assayed high in Cu, Pb, Ag, Zn, As Hg and Sb.
Eagle River and Miner River Resources carried out an reconnaissance program to evaluate some of the quartz-arsenopyrite veins located in the hornfelsed sediment/volcanic rocks. Grab samples collected from veins located on their claim block returned up to 6.7 g/t Au and moderate to highly anomalous values for Bi (3 000 ppm max).
