Oct 31, 2014 (K R Kettles) - The occurence is underlain by mafic metavolcanic flows, mafic intrusives, and chemical metasedimentary interflow units. The metavolcanic flows are massive to pillowed, with tops indicated to the northeast. The flows are variolitic in some areas. The chemical metasedimentary rocks are composed of alternating bands of chert, graphite and graphitic cherts, and the sulphide content varies from nil to 75% over 5 to 8 cm. The mafic intrusive rocks are primarily gabbroic in composition, massive and equigranular. Intense carbonate veining is common within the intrusive. Two zones of anomalous values were noted in drill core. The variolitic metavolcanics are highly carbonized, and gold appears to be anomalously high in quartz-carbonate veinlets and stringers. The chemical metasedimentary rocks contain anomalous values of silver, particularly in the graphitic.

Dec 07, 2005 (K R Kettles) - A 30 cm section of drill core returned assays of 210 ppb Au and 1.6 ppm Ag and a 60 cm section of core assayed at 160 ppb Au.
Dec 07, 2005 (K R Kettles) - The variolitic mafic volcanics and the mafic intrusives are highly carbonatized.
