diamond drilling campaign to commence at anosivola copper gold
19 January 2015 ASX Announcement DIAMOND DRILLING CAMPAIGN TO COMMENCE AT ANOSIVOLA COPPER GOLD PROJECT Aziana is pleased to announce that it has mobilised a drill team and diamond drill rig to commence a drilling program at its 100% owned Anosivola Copper Gold project. Drilling is set to commence the first week of February 2015. Aziana’s technical team has designed the program to test prospects along the Anosivola East to Bevomanga zone (AEB) that have returned a strong magnetic response and high chargeability identified via gradient array Induced Polarity surveying (IP) and additional dipoledipole traverses. The initial program will commence with 4 holes and approximately 1,000m of coring.

The license area is underlain by meta-sedimentary rocks of the Ikalamavony Complex, consisting of a series of amphibolite facies volcanics, schists, gneisses and marbles, intruded by several phases of granitic-dioritic melts. Surface mineralisation consists of malachite, azurite, chalcocite and chalcopyrite with minor bornite in veins and disseminations through the host marbles, gneisses, diorite, and post-tectonic doleritic dykes. The project consists of a single tenement, TN26218, of 87.5 km2 (14 blocks). Exploration Work to Date on the AEB ♦ Ground mapping which located widespread Cu-Ag-Au min along a 6km length of the AEB shear. ♦ Aeromagnetics defined the AEB and interpretation of the data suggested that it was marked by late stage magnetite alteration. ♦ Results from trench sampling have shown very positive results, including primary sulphides at surface, with best channel samples across mineralised veins of: 4.0m @ 7.17% Cu, 45.3g/t Au, and 125.2g/t Ag; 3.0m @ 6.72% Cu, 5.49g/t Au, and 224g/t Ag; 7.3m @ 8.76% Cu, 0.08g/t Au, and 10.72g/t Ag; 3.2m @ 12.37% Cu, 1.20g/t Au and 13.0g/t Ag; 1.2m @ 11.50% Cu, 1.61g/t Au, and 4.1g/t Ag, and 134ppm Mo; and 2.6m @ 4.48% Cu, 4.5g/t Au, and 79.7g/t Ag. ♦ Early stage diamond drilling to date was limited by rig capabilities, but has shown extensive and intense hydrothermal alteration within the AEB. Hole ANDH04 at the north end of the Bevomanga area intersected malachitebearing weathered gneiss from 2-12m and strongly quartz-epidote-chloritemagnetite altered gneiss to total depth of 50m. Assays of half-core from the hole returned 10.2m @ 3.66%Cu, 0.02g/t Au, and 5.8g/t Ag from 1.85m.
