Dec 07, 2005 (B Nelson) - The drill log for J-87-5 indicates the three occurrence grade gold intersections were cut in mafic metavolcanic flows interlayered with thin horizons of iron formation. The intersections are associated with low concentrations of pyrite and pyrrhotite and, in the case of the highest grade interval, quartz veining. Biotite, chlorite and carbonate are mentioned as alteration minerals.
