Capsule Geology

Late Triassic diorite intrudes the Upper Triassic Stuhini Group sediments. The intrusive is comprised mainly of silicified diorite and is in contact with greenstones which host abundant magnetite and epidote. Along this contact the Stuhini sediments are altered to magnetite skarns and the intrusive is described as sericitized andesite porphyry.

In 1929, two claims were located along the east side of the Unuk River across from the mouth of Fewright Creek (Glacier Creek). The claims were located to cover a showing with a high percentage of copper.

In 1989, reconnaissance prospecting was conducted along the lower diorite/sediment contact on the Homer claims in the vincinty of the showings but no mineralization was located.

Work History

The Unuk River (Nine Mile) copper showing (104B 096) occurs on the Homer 1 claim. In 1929, two claims were staked to cover this showing with its high percentage of copper.

In 1929, two placer claims were located near the mouth of Fewright Creek in the northeast portion of the Homer 4 claim. Gravels were reported to carry free gold on the surface, to an equivalent amount of approximately 14 grams/tonne gold.

From 1959 to 1962 Newmont Mines Ltd. conducted a reconnaissance geological mapping and prospectmg program over the entire Unuk River area. This program led to the discovery of a number of showings within or adjacent to the property boundaries.

In 1960, Granduc Mints Ltd conducted magnetometer surveys, soil geochemistry and geological mapping programs. on their Max claims (Assessment File 346). A portion of this program covered areas encompassed by the current property boundaries.

An airborne electromagnetic and magnetic survey was flown over the Homer claims in 1988 (Assessment Report 18585). A number of north-northeast trending, weak to moderate strength conductors were delineated on the property. A strong apparent resistivity anomaly was defined, coincidmg with the Unuk River, possibly outlining an underlying silicified shear zone. A second apparent resistivity low zone was de6ned in the northeastern comer of the Homer 4 mineral claim on the flank of a broad moderate magnetic anomaly.

In 1989, Keewatin Engineering Inc. on behalf of Ferret Exploration Ltd. and Bodega Ventures Inc, conducted a helicopter-supported prospecting, geological mapping and geochemistry (lithogeochemical, stream silt and heavy mineral sampling) program (Assessment Report 19679). Minfile locations and other areas of known mineralization and gossans were investigated and sampled. A total of 6 rock, 18 stream silt and 4 heavy mineral samples were taken.

The 1990 exploration program consisted of helicopter-supported geological mapping, contour soil sampling and stream sediment (Assessment Report 20850). A total of 27 rock samples, 347 contour soil samples and 23 stream silt samples were collected from the Homer 1 to 4 claims. Areas characterized by moderate to high gold-in-soil values were targeted near the common claim boundary between the Homer 1 and 2 claims, in proximity to a magnetite-bearing diorite - intermediate volcanic contact. This area was contour soil sampled and yielded gold-in-soil values up to 648 ppb gold. The south-eastern corner of the Homer 1 claim yielded a strongly anomalous gold-in-stream silt value of 2.23 grams per tonne gold.

The 1991 field exploration program consisted of limited contour soil sampling, stream silt sampling and geological mapping concentrated mostly on the anomalous gold-in-soil area outlined in 1990 (Assessment Report 21976). The infill contour soil samples collected in 1991 yielded values as high as 990 ppb gold and stream silts returned high values of 416 and 44.6 ppb gold, suggesting a mineralized bedrock source. During 1991, 30 rock, 7 silt and 125 soils were collected on behalf of Bodega Ventures and Ferret Exploration Company Ltd.

In 2006 and 2007, Hathor Exploration Ltd. completed a 7228.7 line-kilometre airborne geophysical survey on the area as the Pearly claims of the Iskut project. In 2008, Max Minerals Ltd. examined the property.
