N

• An array of NNE faults in the Nightflower-Red Dome region separate compartments of differing magnetic signature• They are not simply offsetting faults, they are (de)magnetising faults, interpreted as (at least partly) sulphidising

faults• The Nightflower Fault is at least one fault in the NNE array which is mineralising in Au+Ag + base metals. Similar NNE-

trending faults in the Red Dome deposit are also clearly mineralising in Cu+Au+Ag (see later slide).

Nightflower

Red Dome and Mungana both lie within the NW-trending Palmerville Fault.

Their deposit architecture is controlled by NE- to NNE-trending steep faults:

Red Dome deposit is controlled by NE to NNE-trending faults containing crowded porphyry dykes along faults (Torrey et al, 1988, Figs 2, 4)

Mungana’s mineralised stockwork is “preferentially oriented NE” parallel to the Mungana Fault (Nethery & Barr, 1998).

The intersecting faults and replaced host sequence are subvertical, hence the resulting pipes of intrusive porphyry & ore are subvertical.

EXPLORATION STRATEGY

The target PERN deposits possess a mixture of templates:- tabular vs equant- bedding/fault-parallel vs pipes- NW-trending vs NE-trending

They thus demand a sophisticated exploration strategy which 1 Recognises this, then 2 Seeks to identify the correct template very early

in the program, then 3 Optimises the program by selecting (and if

necessary changing to) the correct orientation for geochemical & geophysical surveys & drilling.

PERN metallogeny: related intrusives - characteristics

Spatial analysis of all recorded 151 deposits in the Featherbed Cauldron and hangingwall of the Palmerville Fault shows:

Remarkably strong clustering of the 151 deposits:

1. Each cluster has a very homogeneous metal assemblage. 2. Each cluster is surrounded by a barren region. 3. Adjacent clusters generally have different metal assemblages.

The compartmentalisation of metals is remarkable. Of the 151 deposits, only 12 fail to fit this pattern; a mere 8%.

- mineralisation is strongly controlled by the distribution of intrusives- and by an inferred strong set of faults which control this distribution - the faults take part in the mineralising process- the NNE fault set features strongly

PERN: strong mineralising control by intrusives & faults

The 15 clusters of 151 deposits show a further strong grouping, into3 superclusters, defined by

chalcophile (Cu+Zn+Pb+Ag+Au) vslithophile (Sn+W+Mo±Cu±Pb) metal assemblages.

The 3 superclusters are separated in space and have discrete characteristics. They are:

1. Chillagoe - chalcophile2. Bamford Hill - lithophile3. Nightflower - chalcophile + lithophile
