Two VMS horizons have been successfully delineated at Gravel Pit and are characterised by carbonaceous and siliceous VMS sediment. VMS sediment from the east horizon is hosted wholly within volcaniclastic rocks while the west horizon is classified bi-modal because it is located at the contact between two different rock types, volcaniclastic and mafic volcanic rocks.
Multielement anomalism has been identified within both horizons, consisting of Cu, Zn, Pb, Ag, Au, As, Cd, Sn, Sb, Tl, Ni, Mo, In and Co. This is a typical VMS element mix.
The existence of strong geochemistry in carbonaceous and siliceous sediment demonstrates the potential for economic VMS mineralisation to exist in the sulphide zones.
Drilling is planned to test both horizons.
