PILBARA GOLD PROJECT
The Pilbara Gold Project comprises two granted exploration leases covering an area of 5.57km2 and is located approximately 160km east of Karratha and 38km southeast of the massive sulphide copper deposit at Whim Creek. Access to the area is via the selaed North West Coastal Highway to Whim Creek and then by a graded gravel road to the Yandeyarra Community (Figure 1).
Figure 1: Pilbara Gold Project Location Map
The Project area is dominated by the centrally located Quartz Hill (120m high). Flanking this formation occur open undulating plains comprising in the main Quaternary alluvium of unconsolidated gravel and eluvium of brown and red residual sand and clay.
The Project is partly situated in the Pilbara Well greenstone belt which lies in the North Pilbara granite-greenstone terrane. Regional northeast trending structures occur in the belt and may represent axial fold planes. The Pilbara Well greenstone belt - granite contact and the regional structures are potentially metalliferous.
From the limited rock exposures in the area, the geology of E47/1437 and 1438 consists of granitic gneiss and a north-east trending unit of Archaean mafic amphibolite schists, part of the Pilbara Well greenstone belt, in the northen part. These mafic rocks host the gold mineralization found at Pilbara Top Camp which occurs immediately adjacent to the Project area (Figure 2).

Gold discoveries in the Pilbara Creek area, located 5km south of the Project area, sparked a major gold rush in the Pilbara in 1888. Since then, various groups and individuals have conducted limited gold exploration on E47/1437 and 1438. Old workings occur in the central part of the tenements at Quartz Hill and in the western portion of E47/1437.
The Pilbara Gold Project is mildly prospective for gold mineralization due to its location abutting the Pilbara Top Camp gold deposits, the existence of probable multiple fault zones and the potential gold-hosting mafic rock unit of the Archaean Pilbara Well greenstone belt situated in the northern part of E47/1437 and 1438. The widespread cover of Quarternary sediments has resulted in limited past exploration work. The application of modern exploration methods is warranted over this promising gold project.
It is proposed to conduct a thorough review of previous data. Detailed geological mapping and systematic geochemical sampling over the leases will aim to define drill targets for gold mineralisation.
MOUNT PHILLIPS GOLD PROJECT
The Mount Phillips Gold Project is located 300km east of Carnarvon and 16km east of Mount Phillips station homestead. The Project covers 31.3km2 and is situated 18km southeast of the Bangemall Gold Mining Centre in the Gascoyne Mineral Field. Access to the tenements is via the sealed Carnarvon-Gascoyne Junction road, the graded gravel road from Gascoyne Junction to Mount Augustus and then numerous station tracks to the licence area (Figure 1).

Gold mineralization located in the vicinity of E09/1408, occurs at the Bangemall Mining Centre (discovered in 1896). The geology of the Project area is divided into two parts; a northern Bassit Belt of structurally complex schists and amphibolites and a southern granite sequence of biotite granodiorite, adamellite and dark grey gneissic granodiorite (Minnie Creek Batholith). A sedimentary sequence of coarse-grained quartz arenite and conglomerate of the Mount Augustus Sandstone occurs in the northeast section of E09/1408.
Regional shear zones, trending northeast, north-south and east-west traverse the Project area. These zones of shearing are promising for gold mineralization as a number of quartz vein systems are hosted within the shears. Quaternary sediments cover a central part of the Project. These sediments are composed of aeolian and residual sand. A geological map of E09/1408 is given in Figure 2.

The Company is looking into acquiring the LandSat and process ratio satellite imagery to determine prospectivity for alterion and fault controlled gold targets. Field inspection, mapping and rock chip sampling would aim to recognize all the prospective shear zones. Phase 2 would include a broad stream sediment survey to determine any geochemical anomalism over the tenement area.
