Dec 07, 2005 (K R Kettles) - Iron formation and chert-marble 1.2 to 4.25 m thick lies between two mafic volcanic units that strike N60 degs W and dip 45 degs NE. Numerous fractures in the iron formation are filled with auriferous quartz stringers; in 1937 this gold-bearing iron formation had been exposed for about 120 m along strike, in ten trenches. A quartz vein/shoot occurs in the iron formation and contains gold and sulphides.

Dec 07, 2005 (K R Kettles) - Gold with minor pyrite, pyrrhotite, and chalcopyrite occurs in quartz stringers in the iron formation. which is exposed 120 m along strike. A possible ore shoot is 60 m in length (A.C. Bray, 1937).The iron formation is possibly mineralized over 116 m (Horwood, 1945). Out of 40 grab samples collected in 1937, 30 assayed between 0.03 opt Au and 0.47 opt Au (Bray). Possibly assayed <.10 opt Au over 1.2 m width (Horwood). 2 grab samples collected in 1969 assayed trace gold and silver. Gold and pyrite occur together (Bray).
Dec 07, 2005 (K R Kettles) - The wall rocks containing the auriferous iron formation are silicified.
