Over ten near mine gold targets occur in the immediate vicinity of the Piaba deposit. Luna has conducted several surface exploration programs, resulting in the definition of many drill-ready targets. The near mine targets which occur to the north and south of the main Piaba deposit may occur along separate sub-parallel shear zones/splays or they may occur along flower structures which developed in the principal deformation zone of the Aurizona Shear Zone (ASZ). Additional exploration will define the structural setting of the deposits.
Luna soil sampling and auger drill programs have defined surface geochemical gold anomalies extending to the east and west of the Tatajuba deposit. Tatajuba East is a narrow cohesive gold-in-soil anomaly extending for 600 m east of the current eastern limit of the Tatajuba deposit within the ASZ. Tatajuba West consists of three cohesive gold-in-soil anomalies within the ASZ extending over a 1.5 km strike length from the current western limit of Tatajuba towards the Piaba deposit.
Located 3 km east of Piaba on a parallel east-northeast trending mineralized structure. Mineralization at Micote is associated with quartz veining within saprolitic and altered volcanic and volcano sedimentary rocks. Quartz veins have preferred attitudes of N65E/85NW and N50W/80NE and occur within a north-dipping structural corridor. Mineralization defined to date has approximately 300 m strike extent and is about 25 m thick.
Located 3.5 km east of Piaba and 500 m south of Micote. Gold is associated with a volcano sedimentary sequence with strong carbonate-pyrite alteration and quartz veining. Limited drilling has not yet identified a coherent mineralized zone.
