Capsule Geology

The area of the South Unuk showing is underIain by volcanic and sedimentary rock of the Middle Jurassic Salmon River Formation, Hazelton Group. In 2007, drilling by Kenrich-Eskay Mining Corp comprised two long holes drilled from two separate set-ups on basalt and mudstone. Pyrite and rare sphalerite intergrown were noted in coarser sedimentary horizons.

One notable intersection of massive black banded mudstone in hole CR07-81 yielded a 54-metre section (350.1 to 404.1 metres downhole) that analyzed 0.15 per cent zinc (Assessment Report 30131). This intersection was associated with intermittent stringer-hosted and disseminated to blebby, coarse grained pyrrhotite-pyrite, with a carbonate-quartz gangue in the stringers, in moderately silicified mudstone.

It was concluded by Kenrich-Eskay that, as in 2005 and 2006, the 2007 drilling had intersected a thick but distal portion of the seafloor mineralizing hydrothermal system within the Eskay rift sequence.

See Cumberland (MINFILE 104B 011) for details of the Corey property work history which contains the South Unuk showing and Eskay Creek (104B 008) for details of related mineralization type.
