Held by major companies distracted by other successes No drilling = no discovery Bauloora and Black Range Bauloora • Bauloora • across the 27km2 vein field zone 1 drill hole per 72 ha1 • Black Range • Virtually no exploration across the majority of 905km2(1) • Systematic work not done No modern geochemistry or geophysics • Limited historic electrical geophysical surveys Piece-meal exploration with misidentification of key epithermal textures North Limited (Rio Tinto) Cowal Discovered - focus shifted Newmont and LGM Joint Venture • Geochemistry mostly limited to minimal elements Black Range 1992 1995 2023 Cadia Hill Discovered, Newcrest cease exploration No on ground exploration at Sugarbag Hill since (over 30 years) LGM peg tenement and consolidate with ELA • Lack of pathfinder elements analysed Limited mapping and textural analysis • Textures are key to unlocking the system. Why are we excited? • Geology and terrain is amenable to low cost – high value exploration methods • Bauloora was a breakthrough - the recognition of sinter related lithology makes it one of the world’s oldest preserved epithermal systems • Black Range, dated to have similar age mineralisation as Bauloora, and has a large low temperature silicified upper zone or 'cap’ that may represent the top of a preserved epithermal system.
