The Zak West occurrence is located on a west- facing slope between the two main southern forks of the Nicoamen River, at an elevation of approximately 1275 metres.
The area is underlain by andesitic volcanic rocks of the Lower Cretaceous Spius Creek Formation (Spences Bridge Group). Granodioritic intrusive rocks of the Permian to Triassic Mount Lytton Complex outcrop to the south and west.
Locally, brecciated quartz feldspathic rock with silica, limonite and kaolinite or argillic alteration hosts quartz vein sweats or clasts with up to 5 per cent disseminated pyrite and minor arsenopyrite mineralization.
In 2005, a sample from a trench assayed 0.415 gram per tonne gold (Assessment Report 28146). In 2009, sampling yielded values up to 0.112 gram per tonne gold across 1.6 metres (Assessment Report 31354). In 2016, a rock grab sample (NICO-023) assayed 1.08 grams per tonne gold (Assessment Report 36186).
During 2003 through 2016, Almaden Minerals completed programs of silt, soil and rock sampling, trenching, geological mapping and 21.0 line-kilometres of combined ground magnetic and induced polarization surveys on the area as the Zak claims.
