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 Kununurra-Halls Creek Highway. Currently, Legacy has four granted tenements and three tenements under application covering an area of 370 km2 in this highly prospective area for gold and base metal mineralisation (Figure 1).
Figure 1: East Kimberley Project Location Map
Rocks of the East Kimberley form part of the Early Proterozoic Lamboo Complex. All lithologies of the Lamboo Complex have undergone low- to medium-grade metamorphism. The oldest rocks in the eastern zone of the Complex are the Ding Dong Down Volcanics and the Sophie Downs Granite, which are separated from the overlying Halls Creek Group by an unconformity. The Halls Creek Group consists of the Saunders Creek, Bsicay and Olympio Formations. The Biscay and Olympio Formations have been intruded by the Woodward Dolerite.
RUBY PLAINS E80/3897
The Ruby Plains tenement is centred on the Ruby Queen Mining Centre which is located 27 km south southeast of Halls Creek and 15 km south of the Palm Springs gold mine. Access is good via Duncan Highway and gravel roads to the mining areas. (Figure 1).
The rocks in the area occur within the Lower Proterozoic Olympio Formation described as a monotonous turbidite sequence containing metasediments (greywackes, argillites and shales), chloritic tuffs and andesitic flows (Figure 2).
Prospectivity on the Ruby Plains tenement is high with potential along strike extensions of the mineralised sequence at the old Ruby Queen gold mine. At the Ruby Queen mine, ~22,000oz were mined from narrow 1-3 m wide quartz veins over a strike length of 300 m. The shearing in the mine is part of the regional Ruby Queen Shear Zone that is covered by E80/3897 for 21 km of strike length to the southwest. Promising multiple quartz vein systems up to 4m thick and traceable for 4 km have been observed within E80/3897 with many containing pyrite. (Figure 3).

Legacy has collated all of the existing data on a GIS database and numerous targets have been identified. Process ratio data from Landsat and Quickbird imagery has identified nine alteration targets that require field checking over an area with minimal modern exploration.
Baily Range E80/4221
Baily Range covers an area of 97 km2 and is located 25 km southwest of Halls Creek. Previous explorers have identified broad soil geochemical anomalies of several kilometres in length. Rock chip sampling of stock work quartz veins have returned values of up to 9.2 g/t gold within these anomalous zones. Existing drilling has identified broad low grade intervals including 20m at 0.5 g/t and 9m at 1 g/t gold. Numerous low level soil anomalies require RAB testing in the same stratigraphic horizon that hosts mineralisation at the Palm Springs gold mine.
This tenement is currently under application though Legacy has sourced detailed aerial magnetic and radiometrics survey data (Figure 4). A full review of the available datasets and follow up targeting and ranking is planned.
