The East Kimberley Project tenements are located in the Halls Creek area. Halls Creek occurs 347 kilometres south of Kununurra and is readily accessible via the sealed Great Northern Highway. The tenements comprise seven exploration licences, covering an area of 370 square kilometres in this highly prospective area for gold, base metal and manganese mineralisation (Figure 1).

KOONGIE PARK
Koongie Park lies adjacent to the Koongie Park base metal deposit held by Anglo Australian Resources NL (“AAR”). This is an advanced copper – zinc - gold project with major base metal deposits defined at the Onedin and Sandiego prospects. The deposits are of the VHMS type (volcanogenic hosted massive sulphide) – the same type as the recent discoveries in the Peak Hill district by Sandfire Resources. The project is currently undergoing a feasibility study incorporating extensive drilling. Recent drilling at the Sandego prospect has identified additional high grade copper zinc mineralisation including shallow high grade supergene copper (eg Drillhole SRC061 – 71m @ 5.04% Cu, 7.69% Zn, 68 g/t Ag and 0.43 g/t gold*)
Legacy’s Koongie Park tenement lies adjacent to the AAR ground and contains in its northern sector the same volcanisedimentary package that hosts the base metal deposits identified to date (Figure 2). Much of the area is poorly exposed, but imminently accessible from the main Northern Highway. Although the area has been covered by earlier exploration, much has been reconnaissance in nature and without resource to modern geophysical and geochemical techniques. Indeed, recent exploration and drilling at the known historically well explored prospects such as Sandiego by AAR has resulted in new discoveries of mineralisation. Modern geophysical techniques – in particular surface and down hole EM – have played a large part in recent ore body discoveries as at Sandfire Resource’s Doolgunna Project.

A full analysis of past exploration data is underway, and a geochemical program has been planned to investigate priority target areas, particularly in the Earth Dam and Atlantis South areas. This will likely be followed up with ground EM surveys in due course.
