The Hanna (East Zone) is located in the lower reaches of Hanna Creek. Recent trenching is reported on the north side of the creek but the exact location is uncertain.
The area is underlain by a northwest trending belt of lower greenschist facies Permian(?) to Lower Cretaceous Bridge River Complex (Group) phyllites and schists. These occur in normal and fault contact with Bridge River serpentinized ultramafics, and metasediments of the Lower and Middle Jurassic Ladner Group and the Upper Jurassic-Lower Cretaceous Relay Mountain Group. Late Cretaceous granitic plugs and dykes intrude all of the above units.
The showing is underlain by highly foliated graphitic phyllite and fine-grained siltstone cut by a narrow fine-grained mafic dyke. A northwest trending shear zone, up to 3 metres wide and parallel to foliation, is locally silicified and sporadically mineralized. Siltstones are bleached close to shear zones.
Arsenopyrite occurs as disseminations and veinlets in quartz veins concordant to foliation and within narrow silicified shears. The exposed strike length of the shear zone is 150 metres; widths vary from 2 to 5 metres. Fine visible gold is reported in small quartz stringers and oxidized arsenopyrite cavities.
Two samples of mineralized material assayed 0.4 and 17.1 grams per tonne gold respectively (Assessment Report 12028).
