Regionally, the area is underlain by equigranular biotite- and hornblendebearing granitoids and leucocratic aplite dykes of inferred Early Cretaceous age, comprising the Nisling Range batholith. In general, the Nisling Range batholith varies from non-magnetic granitic compositions in the west to magnetic dioritic compositions further east. Porphyritic dykes are locally noted nearby cutting the Nisling Range granitoids; these dykes may be Cretaceous in age, or may correspond with nearby Early Tertiary intrusive ages documented by Murphy (2011).
The Nisling Range batholith intrudes Snowcap and Finlayson assemblage rocks of the Yukon Tanana terrane (YTT). In the area, the Snowcap assemblage is dominated by siliceous meta-clastic rocks (quartz-biotite and quartz-muscovite schists). Subordinate marble and carbonaceous meta-clastic rocks likely correlate with the Finlayson assemblage.
Mapping the Big Bend target area identified several granodiorite boulders with sheeted quarts-molybdenite veins and parallel sheeted narrow aplite dykes which are similar to gold bearing veins at the Hailstorm occurrence. To date, soil sampling has identified anomalous values of Au-As-Te-Bi-(Mo).
