The Flow Dome area is underlain by Betty Creek formation rocks of the Lower to Middle Jurassic Hazelton Group. The surface geology of the Flow Dome zone is comprised of flow-foliated fine hornblende and feldspar phyric latite and fragmental rocks and well-bedded green, maroon, and grey andesitic to dacitic pyroclastic and epiclastic rocks. The Betty Creek Formation rocks are cut by east and northwest trending dikes of intermediate to mafic composition.

In the Flow Dome zone, high-grade intersections along a broader corridor of mineralization were encountered in holes SU-666 and SU-668 up to 1000 metres east of the Valley of the Kings.

In 2015 six HQ holes were collared on surface in the Flow Dome Zone, with two NQ wedges collared from parent hole SU-671, for a total of 6,199 metres of drilling. Targets were derived from deep airborne magnetometre anomalies (2014 survey and magnetic susceptibility inversion modelling).

The Flow Dome zone extends 2 kilometres northeast and is approximately 400 metres wide. Intersections of quartz-sericite-pyrite altered porphyritic rock were encountered. Two holes, setup as down-dip tests (SU-666 and SU-668) returned gold values, including a quartz-calcite vein hosted electrum sample with 8600 grams per tonne gold and 4330 grams per tonne silver over 0.5 metre at 1,267.45 metres depth in SU-666 (Assessment Report 32614). Fine dendritic electrum was also visible in SU-668, hosted by a less than 1 centimetre pyrite-bearing quartz-calcite vein along a fault. A 28.50 metre interval in SU-668 (from 1143 to 1171.5 metres depth) assayed 0.59 gram per tonne gold and 13.62 grams per tonne silver (Assessment Report 32614).
