target locations and potential

  General Geology of the Project Area

The Hodgkinson Basin Region is host to widespread mineralisation with several major centres of past production, such as the Herberton tin field and the
Palmer and Hodgkinson Goldfields.

 

  • Tungsten is widespread, mainly as wolfram, but also as scheelite in                      association with gold quartz veins.
  • Antimony, as stibnite is a frequent minor associate of gold.
  • Base metals have been found in sub-volcanic settings, such as at the OK            mine.
  • Gold within the Hodgkinson Province occurs in several settings including           skarn deposits of the Chillagoe area and epigenetic gold-quartz veins in the      Hodgkinson and Palmer River Goldfields. The gold-quartz vein deposits are      generally hosted within small fissures or larger reverse faults, as laminated         veins, stockworks or breccia lodes.

 

It is often associated with some pyrite and arsenopyrite and at times galena and sphalerite, chalcopyrite, or stibnite, which may occur as late overprinting veins.

 

There are two main groups of lodes in the Hodgkinson Region:

 

    1. those parallel to the strike of the bedding but dipping in the opposite direction, and

    2. those at right angles to the strike, dipping to the west. 

The lodes consist of quartz stringers or veins of various sizes up to several metres wide that have penetrated the Hodgkinson Formation.

 

Specific Geology of the Key Project Areas

The Hurricane Antimony Project area is situated on a cross extensional fault between the regional Retina and Hurricane faults.


The Holmes Anomaly is located to the west of the cross extensional fault adjacent to a late Permian intrusive Rhyolite.


  • Data to date suggests that the style of mineralisation of the Holmes                Anomaly is that of a quartz gold stibnite hydrothermal system, which is          structurally controlled (strike slip + extensional), transpressional orogenic         environment, however further investigation is required to confirm this.
  • The main brecciated quartz gold vein system consists of a number of               parallel brecciated quartz reefs (exposed) that strike in a south-east                 direction, are sub-vertical in nature and are perpendicular to the cross             extensional fault. The reef cores are noted to contain fault related                     slickenslides indicating a compressional environment, whereas further             away extensional features (veinlets) are noted.
  • Mineralisation is a quartz/gold/stibnite system, with arsenic being an               important indicator element. Further investigation is required to gain a full       understanding of mineralisation, in particular the range of sulphides. This         will assist in determining the best type of remote geophysics to ultilise.
  • The Holmes Anomaly is located to the west of the cross extensional fault        adjacent to a late Permian Intrusive Rhyolite. 

The CycloneTornado and Monsoon reefs are located near the centre and east of the cross extensional fault. The Waterford Reefs (Typhoon, Hurricane North and Hurricane South) are located to the east of the cross extensional fault along the Hurricane Fault.

 

  • that the style of mineralisation of the Tornado and Monsoon Reefs is that of a Quartz/Gold/Arsenic hydrothermal system, which is structurally controlled                 (strike  slip + extensional), transpressional orogenic environment, however further investigation is required to confirm this.
