- •
Complex local structures include S-, E-, W-, and SE-plunging folds, an E-striking strike-slip fault, and a N-trending reverse fault.
- •
Gold zones are hosted in separate S-plunging anticlines close to faults and not in folds in other orientations.
- •
An E-striking triangle zone across the eastern Nadaleen trend probably influenced Au-rich ore fluid migration.
- •
Local structures and the triangle zone may have been influenced by the subsurface ancestral Dawson fault.
- •
The eastern Nadaleen trend gold zones are structurally similar to Carlin-type deposits in Nevada.
