BAM Zone: The BAM Au Zone is located approximately 1000 m northeast of the B4-7 Zone and was discovered during detailed prospecting completed as follow-up to a low-grade, 270 ppb Au analysis obtained from 2003 prospecting sample 218017 (MacTavish 2004). Followup samples 218147 and 218418 contained 3144ppb and 5967ppb Au, respectively, and both samples were enriched in As. Sample 218147 was taken from a mineralized shear located along the southern edge of a small outcrop, whereas sample 218148 was taken from a small, angular, frost-heave boulder located a short distance south of the outcrop. Confirmation samples were taken from
both sample locations once the Au-rich analytical results were received. The discovery outcrop was exposed in September 2003 by Trench T15 (MacTavish 2004). The exposed mineralized zone consists of narrow, anastomosing, locally coalescing, moderately biotitic, variably silicified and carbonatized, variably mineralized shears occurring near the northern contact of a medium- to coarse-grained melagabbroic to gabbroic sill or dyke with pillowed mafic metavolcanic flows. Mineralization is closely associated with alteration, consists of l to 8^0 finely disseminated pyrite and fine arsenopyrite needles, and locally attains widths of 2.50 m. Surface measurements indicate that the strike of the zone varies widely between 0900 and 124" and dips between 730 and 86" to the south. Existing mapping suggests that a structural flexure may exist in the vicinity of the zone. Local plunges were difficult to measure but are thought to be moderate to the west. Mineralized grab samples taken from Trench T15 contained up to 11.94gpt Au and channel samples 1.61 gpt Au/1.11 m and 4.16gpt Au/0.33 m. Anomalous to significant Au values are almost always accompanied by anomalous As, but significant As is not always accompanied by anomalous to significant Au.
