The Blue Zone showing lies along one strand of the Debris Fault system, and is so named for the distinctive blue-green colour of the fault breccias in this area, where the fault zone is up to one half a kilometre wide. The fault bounds the east size of a graben filled with early Tertiary sedimentary rocks. The east side fo the fault is underlain by massive limestone of probable Ordovician age. The fault zone contains intensely sheared and mylonitized limestone and other lithologies. Alteration was probably contemporaneous with faulting (early Tertiary). Alteration minerals include hematite, malachite, bornite?, silica, and chlorite. The hemititic zone overlies the zone of blue-green alteration one sample from this hematitic zone returned a gold value of 8.99 grams per tonne. The extent of this zone of anomalous gold values is not knonwn, although the zone of hematitic alteration continues to the north for at least four kilometres.
