However, it is the Company's opinion that elements considered here have a reasonable prospect to be recovered. 13 1 MoEq (ppm) = Mo (ppm) + (Cu (ppm) / 3.44) + (Ag (ppm) x 34.3) (Dart Mining ASX September 2012) 2 A Resource Update using a new geological model that defines the extent of Oxide, Transition and Sulphide zones is required due to identified variation in the metallurgical recovery for Oxide Mo & Cu zones. Resource update planned during the PFS phase. ASX:DTM RUSHWORTH GOLDFIELD – Central Victoria - Summary Location • Dart Mining tenements cover the entire Rushworth Goldfield, located in Central Victoria, 45km northeast of the Fosterville Gold Mine Style • Rushworth mineralisation is of an orogenic epizonal quartz-vein style that is interpreted to be genetically similar to the nearby Fosterville high-grade gold system Scale • Recent LiDAR processing has identified >4,600 (shallow) historic workings along some 14km of strike • Vastly under-explored Location of historic workings identified in LiDAR imagery, with key historic prospects and Dart Mining tenements identified. Even at this broad scale, structural trends and the orientation of multiple reef systems is apparent – Dart Mining ASX April 2023 Structural model of Fosterville (A) and the Phoenix Hill – Chinaman’s Gully area, Rushworth (B), displaying structural and mineralisation characteristics typical of Central Victorian orogenic gold mineralisation. In particular, mineralisation along limb-thrust faults, is notable of most significant Central Victorian goldfields (Castlemaine, Bendigo, Ballarat, Fosterville, Rushworth).
