Exploration, Mineral Resources

The Nullagine gold Project is located in the Pilbara region of West Australia, approximately 10 kilometres south of the town of Nullagine, and 1,380 kilometres north-north-east of Perth (Figure 1).

Gold was first discovered at Nullagine in the late 1890s, resulting in a gold rush and considerable interest on the London Stock Exchange. By the turn of the century, numerous workings and treatment plants dotted the Mosquito Creek belt and, according to Western Australian Department of Mines, by the end of 1937, 47,380 tonnes ore returning 78,108 ounces of gold and 8,904 ounces of silver from alluvial sources and dollied specimens is recorded to have been produced.

Millennium acquired a significant package of tenements in May 2001. All land involved in the project (except the accommodation facility located in Nullagine), is subject to native title. Individual native title mining agreements have been signed with the Njamal and Palyku people.

Geology Overview

The mining tenements that underpin the Nullagine Gold Project cover an area of 264 km2 within one of the oldest, and perhaps least explored goldfields in Western Australia.

The Mosquito Creek Belt is a typical Archaean turbidite-dominated, metasedimentary thrust belt in which gold mineralisation is structurally controlled by faults and quartz vein arrays that appear to have channelled gold-bearing fluids away from broader shear zones, which are located nearby and are recognised as the major conduits for regional-scale fluid flow.

In most deposits, including those that comprise the Bartons, All Nations and Golden Gate resources, gold is sited within or near the margins of steeply inclined quartz veins. The exception to this style of mineralisation is the large Golden Eagle deposit, which is characterised by gold disseminated through fractured wall rock that surrounds a series of gently inclined faults.

In outcrop, the Golden Eagle mineralisation is not accompanied by obvious wall rock alteration and, significantly, there are no historic workings developed on the zones of disseminated mineralisation, despite grades as high as 50 g/t Au. These features suggest that there is the potential for locating other, large-tonnage, Golden Eagle-style resources outside of the known mining centres within the Nullagine goldfield.

Apart from the current known resource base, there is clear exploration upside attached to the project area by virtue of the significant strike length of mineralised structures that are encompassed by the project, and the fact that much of the area has not been tested by modern, high-quality exploration of the type that Millennium can apply.

Millennium is focused on establishing a sustainable gold resource base and is making significant progress in developing an in-depth understanding of the regolith and bedrock geology of the Mosquito Creek Belt.
