The Bird area is underlain by andesitic rocks of the Eocene Endako Group and rhyolite and felsic rock of the Eocene to Oligocene Ootsa Lake Group. Geology layers on government website MapPlace (for some mapsheets) indicate that Endako and Ootsa Lake packages are now formations of the Nechako Plateau Group.
Mineralization with anomalous gold, silver, arsenic and antimony concentrations is found in scattered outcrops of silica-rich veins with steep dips as well as silicified conglomerates that are interlayered with the volcanic rocks. In descriptions of the drill holes the conglomerates are often mineralized, micro-fractured and exhibit vein fillings of silica and carbonate. Taken together with the clay alteration and sulphide mineralization, the silicification may be interpreted to be associated with a hydrothermal or epithermal system.
Mineralization in one of the 2008 drillholes (NEC-08-05) comprised locally disseminated and fracture-fill sulphides, including pyrite, pyrrhotite and minor chalcopyrite. In the other hole (NEC-08-06), sulphides comprised mainly pyrite and marcasite often as fine-grained masses lining cavities indicative of open space fill and infill in breccia units rimming the breccia fragments. Sulphide mineralization was persistent throughout the hole and resembled a silicified, high level sulphide cap atop a buried epithermal system. The best results from 2008 drilling were 0.09 gram per tonne gold, 3.7 grams per tonne silver and 115 parts per million arsenic over 22.00 metres, including 0.15 gram per tonne gold, 6.6 grams per tonne silver and 111 parts per million arsenic over 8.0 metres from the upper portion of the hole (hole NEC-08-06, Assessment Report 30364).
WORK HISTORY
In 2008, two drill holes and an IP survey grid were located on the claim group and were conducted by GMV Minerals Inc. (Assessment Report 30364). NEC-08-05 was drilled in the north-central portion of the grid to test a coincident high resistivity - high chargeability IP response. NEC-08-06 was collared in the southeast area of the grid to test a large high chargeability - low resistivity IP response.
A cursory rock sampling has been performed on the property in 2010 by Kootenay Gold Inc who collected 52 rock samples (ARIS Report 32069).
In 2012, Kootenay Silver Inc. collected 44 biogeochemical samples and 13 rock samples. Rock sampling reveal anomalous copper mineralization found in association with a northwest panel of epidote, hematite and pyrite alterations. The exposed zone is in excess of 100 metres wide and extends beyond 4 kilometres. Epidote alteration is the most obvious and important in defining the existence of copper mineralization, especially when accompanied by a reddish coloration. A sample of tuff outcrop with epidote, pyrite and limonite and assayed 0.23 per cent copper, 1.7 grams per tonne silver and 0.11 gram per tonne gold (sample SAK 12-31, Assessment Report 33295).
In 2013, 55 samples were collected on the Bird claims were collected by Kootenay Silver Inc (Assessment Report 34636). Exposures of rock on the Bird property are limited and where seen and sampled low levels of gold were obtained. Elevated gold values show a correlation to elevations of arsenic, antimony, molybdenum and mercury. Low to moderately elevated levels of both copper and zinc were also obtained and show a good relationship to each other. The highest value for gold was collected from a piece of rhyolite float.
