A smaller, 1 kilometre diameter Lower Cretaceous Bulkley Plutonic Suite feldspar porphyry stock is exposed at the War Eagle Pyrite zone. The stock is emplaced within andesitic volcanic rocks of the Lower Jurassic Telkwa Formation, Hazelton Group.
The War Eagle Pyrite zone, 800 metres southeast of the main War Eagle showing, consists of a 15 to 25 metre wide iron oxide zone coincident with an induced polarization anomaly and associated with a 305 degrees trending shear zone mineralized with pyrite and minor chalcopyrite with quartz stockworks, stringers and local breccias evident (Assessment Report 3485). The zone occurs within a felsic feldspar porphyry plug, 500 by 700 metres in size with copper soil anomalies. A drill hole in the southern part of the stock intersected porphyry style alteration and significant gold results but no significant copper mineralization.
Work History
From 1966 to 1970, Pathfinder Resources Ltd. Completed a 2.5 kilometres induced polarization survey, soil geochemical surveys, and in 1968 a deep drill hole. A broad east-west trending magnetic anomaly and copper soil anomalies were outlined associated with a stock at the War Eagle pyrite zone and the drill hole intersected porphyry style alteration (Assessment Report 3485).
A previous diamond-drill hole record was uncovered from the War Eagle Pyrite showing indicating results of 24.0 and 9.43 grams per tonne gold, each over 3.05 metres, which had not been followed up (Assessment Report 31515). The hole was re-located in 2008.
In 2009, significant results were obtained from the War Eagle Pyrite zone, 800 metres southeast of the main War Eagle showing, adjacent to the northern finger of the War Eagle feldspar porphyry stock in 2008. Quartz-chalcopyrite float hosted by andesite on the eastern edge of the finger yielded 6.74 per cent copper and 99.8 grams per tonne silver (Assessment Report 3485). On the west side quartz-pyrite veinlets and adjacent silicified andesite yielded maximum values of 1.32 per cent copper and 31.6 grams per tonne silver (Assessment Report 3485). Soils from this area yielded maximum values of 0.196 per cent and 0.0064 per cent molybdenum (Assessment Report 3485). No significant values were obtained from within the War Eagle stock but soils from the western edge yielded anomalous values up to 282 parts per million copper (Assessment Report 3485).
