Slide 4: Georgina Basin IOCG Project
Georgina Basin IOCG Project Barkly Tablelands, east of Tennant Creek has been subject to substantial exploration focus For personal use only over the past few years Greenvale through is wholly owned subsidiary, Knox Resources was an early explorer within this region Thirteen Exploration Licences/App
Slide 5: Regional Geology
Regional Geology For personal use only ● The Warramunga Formation is characterised by turbiditic felsic volcanic derived sediments and felsic tuffs (deposited about 1862 Ma) under Georgina Basin cover sequences ● Syn-tectonic intrusive rocks of the Tennant Creek Suite comprising granites and quartz
Slide 6: Initial Data Compilation
Initial Data Compilation For personal use only ● Greenvale tenement holding in three distinct locations between the IOCG provinces of Tennant Creek and Mount Isa ● Initial focus on EL32282, EL 32296 and EL32295 where detailed geophysics data was acquired during 2021 under the Geophysics and Drilling
Slide 7: Geophysics and drilling collaboration program
Geophysics and drilling collaboration program For personal use only ● Existing Project area datasets include aeromagnetic data at 200m- 400m line spacing and gravity of 2km x 2km and 4km x 4km station density ● In 2020-2021, geophysical infill programs across central and western tenements including
Slide 8: Interpreted Solid Geology
Interpreted Solid Geology • solid geology and structural interpretations conducted at 1:25,000, integrating: For personal use only • detailed magnetic and gravity data, • published 1:100 K geological mapping, • published solid geology interpretations of NT Tennant Creek and Frew River • open-source
Slide 9: Depth to Basement Modelling
Depth to Basement Modelling For personal use only ● Calculation of depth to magnetic sources by Euler deconvolution was undertaken by Resource Potentials. ● All sources modelled by this method included surficial, intra- basinal (e.g., Cambrian volcanics), top basement and deep crustal sources. ● Sep
Slide 10: Exploration Targeting
Exploration Targeting ● Mineral systems analysis and exploration targeting was conducted focusing on the Tennant Creek style IOCG mineral For personal use only system ● Process aimed to break down the mineral system components (fluid source, fluid driver, fluid pathway and fluid trap) and define the
Slide 11: Exploration Targeting – Twin Peaks
Exploration Targeting – Twin Peaks For personal use only • Two key targets identified in EL32282 and 32296 included the Twin Peaks targets • Defined as two discrete magnetic highs bound to the north and south by major E-W trending shears • Detailed gravity assisted in defining two discrete slightly
Slide 12: Twin Peaks - Drilling Results
Twin Peaks - Drilling Results For personal use only KNRDD002 • Two holes have been drilled, targeting the east and west Twin Peaks targets – have provided valuable insight into the geology of this region • KNRDD002 intersected a ‘cover sequence’ of Georgina basin limestone, Helen Springs basalt and

Slide 19: Exploration Targeting – Mawson, Banks & Leichhardt
Exploration Targeting – Mawson, Banks & Leichhardt For personal use only • Further targets have been identified within EL32295 • Targets form as coincident magnetic and gravity high features in structurally favourable locations with proximity to granodioritic intrusives • Preliminary drill targeting
Slide 20: Conclusions
Conclusions For personal use only • In the absence of outcrop geology, exploration is relying heavily on geophysical techniques • Acquisition of the detailed aeromagnetic and gravity data under the Geophysics and Drilling Collaborations Program has greatly helped to further the geological understand
