Gascoyne Project

The Gascoyne Project comprises 100% owned tenements covering 537km2 located in the Gascoyne Region, Western Australia. It is located approximately 250km to the east of Carnarvon and 1,200km north from Perth.

The Project area is highly prospective for Broken Hill-style silver lead zinc ore bodies and quartz vein-hosted gold lodes. Secondary targets include manganese, tungsten, tin and tantalum.


The Gascoyne Project covers an area of mid-Proterozoic aged, metamorphosed sediments and volcanic rocks which have been subjected to several phases of tectonic deformation and intruded by granitoids. Exploration work and drilling to date has used the geological model of base metal mineralisation being associated with coincident soil geochem and “thumbprint” magnetic anomalies.

Historical RC drill testing from one of these targets has returned significant intercepts of 2.3% Pb and 0.9% Cu. Lead sulphide (galena) and copper sulphides (chalcopyrite) were identified in the drill chips.


Activities conducted by Audalia at the Gascoyne Project to date included completing:

    • an IP survey programme
    • regional and detailed geological mapping;
    • 323 rock chip samples;
    • 696 trap stream sediment samples;
    • 44 stream sediment samples
    • 257 soil geochemistry samples
    • IP 100m dipole-dipole traverses on 6 N/s lines @ 300m;
    • Aerial magnetic & radiometric survey @ 100m line spacing; and
    • Airborne Electromagnetic (EM) survey @ 200m line spacings.

The results concluded that the Gascoyne Project has two sub-economic gold prospects, plus a number of gold and base metal geochemical anomalies that warranted further exploration. These include:

Rock chip gold anomalies:

CW697        25ppb Au      382,014E 7,284,681N        20m by 30cm ironstone
CW1028      61ppb Au       383,524E 7,271,435N         40m by 20cm weakly manganese/ iron-stained quartz vein

CW1039      82ppb Au       386,854E 7,272,789N        10m by 5m patch with 89ppm As sparse ironstone and quartz float
>1000ppm Ba
1113ppm Mn
56.3ppm Mo

Rock chip base metal anomalies:
CW978      >1000Ba         376,324E 7,278,402N         10cm by 10m subcropping 469Cu manganese-rich(?) band.

CW989      867Cu             368,526E 7,284,387N          Small patch of subcropping 2385Mn ironstone and vein quartz

CW1024    2589Mn         378,242E 7,283,903N          3m by 1m subcropping 1327Zn ironstone
CW1087     2.55Ag           363,331E 7,281,703N           Gossanous(?) quartz vein 25As float near BIF

CW999      1022Pb          385,554E 7,274,359N           1m diameter subcropping ironstone
CW1004    1445Pb          378,372E 7,284,992N           100m by up to 1m ironstone

Values are in ppm unless otherwise indicated.

Manganese haloes of 2 to 5% are recorded in banded iron formations around the Broken Hill ore bodies. BIFs in Audalia’s tenements recorded up 6.84% manganese in rock chip CW1084; this sample consisted of 5cm thick magnetite BIF subcrop and float, located at 368,617E 7,290,083N. The next highest manganese value in BIF was 1.36%.
