Geology • Deposit type, geological setting and style of mineralisation. • The project area lies within the Far Fanning ore-body is developed in Late Devonian ▇▇▇▇▇ Point – Walhalla Synclinorium structural domain Formation of the Melbourne ZoneDotswood Group, overlying the Fanning River Group. The rocks are folded into parasitic folds with associated kink bands, and intruded post-folding by Carboniferous to Permian rhyolitic plugs and ▇▇▇▇▇. Bulging associated with the intrusion and dyke emplacement led to a local increase of fold plunge across the intrusion, a northwest trending belt process that is inevitably accompanied by normal faulting. Mineralisation is hosted in bedding-parallel veins within an envelope controlled by the orientation and geometry of tightly folded Early Devonian Walhalla Group kink bands. The broad structural zone at Far Fanning is delineated over a strike length of 1700 metres, trends west to north-west and is characterised by open fold structures at the eastern end of the deposit and monoclines throughout the rest of the deposit. The deposit consists of numerous ore lenses. These ore lenses parallel and cross cut bedding and vary in width from 2 metres to over 20 metres. The overall dip of the ore lenses is roughly normal to the direction of maximum steepening of the fold. Therefore, although the beds in the fold flexure mainly dip to the south (60 to 80 degrees), the ore lenses dip to the north (35 to 50 degrees). In detail ore lenses consist of discontinuous mineralised fracture sets and metric size clast supported breccia pods (▇▇▇▇▇▇▇ turbiditesand Houtgraaf, 1986) Gold mineralisation is reported to be associated with quartz-sulphide stringers and veinlets minor breccias and disseminated sulphides. The domain is bounded by the Enoch’s Point and ▇▇▇▇’▇ Creek Faults, both possible detachment-related splay structures that may have controlled the intrusion Approximately 80 - 85% of the gold is free milling. Structural control on the orebody is reportedly a combination of: • a ▇▇▇▇▇▇ Point model with mineralisation controlled by shearing and fracturing within a low strain shear zone resulting in a kink set configuration (▇▇▇▇ Swarm and provided the conduits for gold bearing hydrothermal fluids. The local structural zone is referred to as the ▇▇▇▇ Creek Fault Zone, 1987); & • Three-phase folding control, with syngenetic source of metal and mineralisation concentrated within cleavage planes and fold axes. • Most gold mineralisation in the (▇▇▇▇▇▇ Point to & ▇▇▇▇▇▇▇’▇ Creek corridor occurs as structurally controlled quartz vein-shear zone systems hosted by dioritic dyke bulges.
