Slide 10: Victorian Geology
VICTORIAN GEOLOGY NSM is positioned in the highly prospective western margin of the Stawell Zone, Victoria. For personal use only • The Stawell Zone has 6 Moz historic production. Gold-prospective basement geology comprises folded and faulted meta-sedimentary rocks with minor volcanics. • Gold Miner
Slide 11: Victorian Cover
VICTORIAN COVER The Murray Basin is a blanket of un-mineralised* sediments that obscures (and preserves) gold-prospective geology For personal use only • The Murray Basin cover was an effective barrier to historic prospecting - preserving the underlying, near-surface gold potential. • A Victorian Go
Slide 12: Stawell Zone Cover
STAWELL ZONE COVER Although an impediment CORPORATE & TEAM to simple surface exploration, the Murray Basin cover sediments preserve potential for shallow, multi-million ounce gold. For personal use only • The gold-prospective Stawell corridor geology and structures disappears under cover only 6km no
Slide 13: Stawell Zone Geology - An Important Difference
STAWELL ZONE GEOLOGY – AN IMPORTANT DIFFERENCE Large slabs of basalt occur at Stawell and form a focus for gold mineralisation. Basalts are readily targeted with geophysics at depth and through cover. For personal use only basalt sedinent faults Cross section of the Stawell Mine. mineralisation The
Slide 14: 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 15: Type Deposit - The Wonga Mine
“TYPE” DEPOSIT – THE WONGA MINE The Wonga Mine has historic production of 294koz Au. Mineralisation is related to the granodiorite that intrudes to the south. For personal use only Deposit model Wonga-type Gold N Intrusive-related Gold (IRG) Thermal Aureole Gold (TAG) Gold (Moz) 50k - 2Moz Au target
Slide 16: Type Deposit - Other Historic Mines
“TYPE” DEPOSIT – OTHER HISTORIC MINES 393koz Au at 19 g/t Au from historic mining on NSM footprint. For personal use only Wonga 290koz Au at 4.31 g/t Au 393koz Au at 19 g/t Au have been mined historically (GeoVic 2021). Image Data Source: “Geovic” historic mines data https://earthresources.vic.gov.a
Slide 17: Type Deposit - Wildwood Resource
“TYPE” DEPOSIT – WILDWOOD RESOURCE 55,000 oz Au at 2 g/t Au Inferred Mineral Resource (1g/t Au cutoff). Wonga may be the only Victorian greenfield gold discovery in 20 years. For personal use only Wildwood is a technical success – demonstrating orogenic gold on the crest of the Wildwood basalt dome.
Slide 18: Geophysics - The Right Tools for the Task
GEOPHYSICS – THE RIGHT TOOLS FOR THE TASK To “weaponise” geophysics for exploration, AGG gravity was acquired. Other products include structural analysis and 3D inversion (shapes) For personal use only Ground Gravity - 287 Ground stations Falcon AGG lines (E-W), Equivalent to 55,400 stations, spaced
