The area is underlain by rocks of the Upper Paleozoic Stikine Assemblage consisting mainly of fine-grained, dark clastic sedimentary rocks and intercalated volcanics. They have been intensely folded and sheared with the consequent development of slaty cleavage and foliation. Secondary mica has formed in most of the sedimentary rocks giving it a phyllitic texture. The volcanic rocks have been converted to mainly greenstone and chlorite-amphibolite schist.

The occurrence consists of a well-defined shear zone traceable for about 91 metres between elevations 33 to 50 metres above the river. The shear zone is similar to the Surveyor (MINFILE 104K 016) and strikes 310 degrees and dips 60 degrees south. Mineralization consists of massive and disseminated stibnite with some finely disseminated pyrite in a gangue of quartz and lesser calcite. Oxides of antimony are widely distributed. The shear cuts metamorphosed rocks, mainly argillites, quartzites, and schists.

A green diffusion band, about 46 centimetres wide within the mineralized shear, was described as an insoluble silicate coloured by chromium with some iron and trace nickel. Possibly, this may be mariposite within the gangue exposed in an upper cut. In 1930, a sample of this band assayed trace gold, silver, and nickel with no copper. A sample of dark, quartzose-sheared material with antimony oxide from the lower showing returned traces of silver and gold. A sample from the same cut with stibnite and some gangue returned no gold and silver (Geological Survey of Canada Memoir 243).

Work History

In 1930, a group of six claims called the Council was located near the mouth of the south fork of the Taku River and was owned by Joe Hill and associates of Tulsequah. No work since 1930 is documented.

In the early to mid 2000s, the Council area was staked as part of the Taku property owned by Optima Minerals Inc. The Taku property was visited and sampled by Optima Minerals though no work in Council area occurred.
