Deposit type

  • Orogenic
  • Vein / narrow vein

Summary:

The deposit type is classified as a hybrid Archean orogenic gold-copper deposit within the Gullewa greenstone sequence. The deposit comprises a series of en-echelon veins hosted within a flexure in the greenstone stratigraphy.

Locally, the mineralisation is hosted in five main vein sets, the Western, Central, Da Vinci, Contact and Deflector South West Lodes. Ongoing work at Deflector Southwest indicates that it is likely the continuous strike extension of Western domain. The main lodes are narrow, sub-parallel, fault-hosted, quartz-sulphide veins within a thick sequence of high-Mg basalt intruded by a series of dacitic, dolerite, and lamprophyric dykes. The mafic sequence is bound in the east by a volcanic-clastic unit, and in the west by an ultramafic unit. The metamorphic grade is defined as lower green-schist facies.

The Deflector resource extents are 1,600m strike, 430m across strike and 630m below surface and open at depth. These extents host approximately 56 known ore zones (ore domains). The ore zones vary between 0.3 to 5m in width. Domain continuity was extrapolated to half the average drill spacing.
