Big Blow Trend
Big Blow South is located 3.7 kilometres south of the Excelsior Deposit and 600 metres southeast of the Parkerville prospect.
High grade gold mineralisation is hosted within a porphyry unit which is intruded on the contact between the Big Blow Chert and underlying ultramafics. The current Indicated and Inferred resources at Big Blow South are
325,400 tonnes @ 2.64g/t Au for 27,600 ounces (at 0.6g/t Au cut-off)
The gold mineralisation extends 200 metres along strike and down/dip plunge to 200 metres depth.
The deposit offers both open pit and underground mine potential and is significant as it demonstrates primary, high grade gold mineralisation persists at depth along the Big Blow Trend. The Big Blow Trend is a stratigraphic marker horizon within the Bardoc Tectonic Zone and is traceable over 25 kilometres of strike within the Kalgoorlie North Gold Project tenements. The unit hosts numerous high grade gold drill intercepts which now have added importance in light of the new geological model for the Big Blow style of gold mineralisation.
