The Valley area is underlain by interbedded limestone and argillite Carboniferous to Jurassic Cache Creek Complex.
The 2006 reverse circulation and follow-up diamond drilling program by Alpha Gold Corp to evaluate the sediment hosted gold potential in the limestone and argillite surrounding the historic Takla-Bralorne Mercury Mine (093N 008) resulted in the discovery of the Valley Zone (Assessment Report 29090).
Reverse circulation rotary hole LRC06-23 yielded 11.02 grams per tonne gold over 7.6 metres from 68.6 to 76.2 metres including 46.9 grams per tonne over 1.5 metres. Follow-up diamond drill-hole LD06-31 yielded anomalous gold values over 21.3 metres from 89.0 to 110.3 metres and over 9.1 metres from 192.6 to 201.7 metres including 2.6 grams per tonne over 1.5 metres in unaltered limestone without visible mineralization. Follow-up diamond drill-hole LD06-32 returned anomalous gold values over 7.6 metres from 121.0 to 128.6 including 1.865 grams per tonne over 1.5 metres in unaltered limestone without visible mineralization.
The lack of sulfide mineralization, the host rock and mercury trace element association, and the spatial relationship with the skarn and manto mineralization, are thought to be indicators of the potential to discover a sediment-hosted gold deposit in this area.
