Capsule Geology

Rocks in the area of the Honk showing are reported to be mafic volcanic rocks, intruded by a large Triassic stock of monzonite to monzodiorite with smaller lenses of Late Triassic ultramafic rock bordering the stock. The volcanic rocks are augite phyric mafic flows, probably with affinity to the predominant volcanic in the area, a Mississippian unit of the Stikine Assemblage. The mineralized zone occurs in the area of a north-trending splay of the Ophir Break fault zone.

The Honk occurrence is a shear-hosted quartz-pyrite vein with local chalcopyrite mineralization in sheared, chloritized mafic volcanic rock that was originally thought to be an ultramafic rock. The fragmented vein and accompanying limonite alteration is up to 3 metres wide and can be traced along strike for 70 metres and is open in all directions. Post-mineralization shearing has produced pods of solid vein material surrounded by yellow limonitic gouge containing quartz fragments. The best of 29 samples taken from trenches in 1992 yielded 13.1 grams per tonne gold, 154.34 grams per tonne silver and 2.37 per cent copper (Assessment Report 21947).

In 1990, Homestake Mineral Development Company, under contract to North American Metals Corp., discovered the “Ultramafic Zone” occurrence and collected 5 rock samples. In 1991, Homestake trenched the Ultramafic Vein” at 11 sites. Twenty-nine samples were taken from trenches on a grid in the area.

Please refer to the Nie occurrence (104K 0810) for further details of the area geology and a common history of exploration.
