Multiple conductors with VMS potential identified at
Emu Creek Project in WA’s Pilbara
Plus, geo-physics program underway at nearby Talga Gold Project
First Au (ASX: FAU) is pleased to announce that a geo-physical survey has identified eight conductors
at its Emu Creek gold-base metals project in WA’s Pilbara.
The conductors at Emu Creek, where First Au is earning a stake of up to 70 per cent from Atlas Iron
(ASX: AGO) were outlined using a helicopter-borne (VTEM) electromagnetic geophysical survey
Four of these conductors are thought likely to be associated with volcanogenic massive sulphide (VMS)
style copper-gold-lead-zinc mineralisation.
First Au will now undertake a field examination of the eight conductors to determine if their source
can be identified in outcrop.
Those conductors deemed prospective will be traversed with moving-loop EM (MLEM) surveys to
better define drilling targets.
The VTEM survey is the first geophysical survey to target massive sulphide mineralisation on the Emu
Creek tenements.
The Emu Creek project is prospective for VMS mineralisation associated with rock units of the
Archaean Kelly Greenstone Belt which underlays much of the project area. These rocks consist of a
sequence of mafic and felsic volcanic rocks and numerous porphyry intrusive units.
Previous explorers of this area have noted that the volcanic and porphyry assemblage outcropping
represents a former active, near-vent environment, suitable for hosting VMS mineralisation, with
intense alteration of the volcanic units mapped over a wide area. A number of small copper mines
have been worked in the past with numerous smaller copper occurrences mapped by various
explorers.
Recent work has included acquisition and interpretation of hyperspectral and Landsat images of the
entire project area. This outlined the location of large areas of minerals associated with hydrothermal
alteration within the mafic and felsic rocks in the centre and south of the project. This mineral
alteration is interpreted to indicate the former presence of two large hydrothermal cells which
crosscut both the Euro Basalt and Wyman Formation volcanic units.
It is well documented in the geological literature that such hydrothermal cells are spatially associated
with VMS deposits and vein-style deposits.
FAU’s Emu Creek Project was a recent recipient of a $150,000 drilling grant from the Western
Australian Government Exploration Incentive Scheme.
