Slide 3: Project Status
Project Status For personal use only • Gold first discovered on Horn Island in 1894 and the first bulk mining undertaken in 1907 • 1987 Torres Strait Gold Pty Ltd (subsidiary of Augold NL and Giant Resources) started open-pit mining. 1989 when the mine was shut down due to poor performance. (6Mt exc
Slide 4: Geology Setting
Geology Setting For personal use only Horn Island • HI Isolated, basement unknown • Early Carboniferous (350Ma) ignimbrites • And granite (342Ma) & Mo(Sn W) min Au • Age c.f Kangaroo Hills Sn, Drummond Au • Mid Carb deformation NW orientation • Late Carboniferous NW trending TMIB Sn • 320-310Ma rhyo
Slide 5: N-S geology, NW mineralised structures
N-S geology, NW mineralised structures For personal use only • Early Carboniferous • 342Ma POR MCG • Badu Granite QKP • N-S shallow phases POR POR • Mo(Sn W) min EQI • Mid Carb deformation RD dike • NW shears, • SW-dipping thrusts • Late Carboniferous • 320-310Ma • rhyodacite dikes • Au min • in thr
Slide 6: Metal Zones related to Badu granite facies
Metal Zones related to Badu granite facies For personal use only • There is a distinct relationship of Sn W Mo Bi with the facies in the Badu granite • This suggests they are genetically related • Sn with MGC, W with EQI, Mo-Bi with POR above and below basal fault; Te with Mo especially above baseme
Slide 7: Au Zones-rhyolite basal fault relations
Au Zones-rhyolite basal fault relations For personal use only • Elliptical body shallow plunge towards NW and a steep feeder below • Rhyolite dike is late-post mineralisation and cuts out ore but has good ore adjacent • Basal fault terminates mineralisation and offsets rhyolite dike ~250m to NE Th

Slide 15: Conclusions
Conclusions For personal use only The metal zoning patterns indicate: • that the gold system footprint extends across most of Horn Island • the two main gold structures have km scale extensions • both structures have only been tested in their shallow parts. ASX:AQX Alice Queen Limited 15
