Slide 6: Stawell Zone and Murray Basin Cover
STAWELL ZONE AND MURRAY BASIN COVER The Murray Basin CORPORATE is an impediment to historic (and modern) exploration BUT & TEAM these sediments preserve potential for shallow, multi-million ounce gold. For personal use only • The gold-prospective Stawell Corridor geology and structures disappear und
Slide 7: "Type" Deposit - The Stawell Mine
“TYPE” DEPOSIT – THE STAWELL MINE The common feature for all Stawell mineralisation is that it’s near the margins of the basalt core. For personal use only Deposit model Stawell-type Gold Orogenic Gold (Ballarat, Bendigo) West flank – 4km strike, 1km down-dip, Dome-related Gold (Homestake) shallow p
Slide 8: "Type" Deposit - The Stawell Mine

For personal use only Typical (but not always) mag response Gravity -ve response Gravity +ve response Deposit model Stawell-type Gold Orogenic Gold (Ballarat, Bendigo
Slide 9: Wildwood 2021
WILDWOOD 2021 NSM had an early focus on the Wildwood Project. Offset of the faulted margins of the dome were not resolved during drilling, impacting the Project pathway. For personal use only 2020-2021 work targeted Wildwood as a priority target Upside? Offset to depth & along dome hinge to south. F
Slide 10: Regional Data - The Right Tools for the Task
REGIONAL DATA – THE RIGHT TOOLS FOR THE TASK To “weaponise” geophysics for exploration, AGG gravity was acquired. Other products include structural analysis and 3D inversion (3D shapes) For personal use only Ground Gravity - 287 Ground stations Falcon AGG lines (E-W), Equivalent to 55,400 stations,
Slide 11: Regional Data - The Right Tools for the Task
REGIONAL DATA – THE RIGHT TOOLS FOR THE TASK Working with a best-available dataset (including geo-knowledge) to effectively test and rank Stawell-like targets under cover. For personal use only Footprint of 4.9 Moz Au Stawell Gold Mine. Structure and Historic edge detection Drilling data Interpreted
Slide 12: Regional (Phase 1) Drilling Targets
REGIONAL (PHASE 1) DRILLING TARGETS Wide-spaced vertical AC drilling answers the most important question – is there gold in the interpreted Stawell-like structure? For personal use only ~20 priority targets 25,000m of AC drilled (2022) 133 of 406 Phase 1 holes have encouraging anomalism. • 49 requir
Slide 13: Phase 2+ Drilling and RC - Positive Results
PHASE 2+ DRILLING AND RC - POSITIVE RESULTS Demonstrates primary mineralisation and/or determines geometry (strike and extents, dip, approx. grade and thickness) For personal use only 15,000m AC follow-up and infill programs + 2 new regional programs Ashens + Deeper holes under maturing targets (?)
Slide 14: Regional Application of the Stawell Model
REGIONAL APPLICATION OF THE STAWELL MODEL The geophysics-responsive basalt cores allow assessment of position in potential larger gold systems For personal use only Typical (but not always) mag response Targeting the margins or the ‘roof’ of Gravity -ve response Gravity +ve response interpreted basa
Slide 15: Geological Advantage
GEOLOGICAL ADVANTAGE NSM Advantage: A model that responds directly to geophysics and a well-studied type-deposit accessible to the geology team For personal use only Stawell Zone “Typical” Geophysics Victorian response Geophysics response 2km The Stawell-type gold mineralisation is, in 40 years of m
Slide 16: "Type" Deposit - Wildwood Resource
“TYPE” DEPOSIT – WILDWOOD RESOURCE 55,000 oz Au at 2 g/t Au Inferred Mineral Resource (1g/t Au cutoff). Proof of concept for Stawell-type gold under cover. For personal use only Wildwood remains the “most recent” greenfield maiden gold resource in Victoria (2006). Discovery snapshot: Inferred Minera
Slide 17: Better Science Better Exploration
BETTER SCIENCE BETTER EXPLORATION Using the science to “do the heavy lifting” has huge potential to continue to vector towards mineralisation in Stawell-type systems. For personal use only N N N 500m 2km 500m Inversions of airborne gradiometry and Regional Mineral Prospectivity In collaboration with
