Slide 5: NSM Geology and tenements
NSM Geology and tenements 504km2 of tenements over the gold-proven Stawell Corridor – see Appendix 1 Immediately north of the operating Stawell Gold Mine (SGM) – but masked by unmineralised sediments (“cover”). Mineralisation occurs during the same gold events as Central Victoria – why not host simi
Slide 6: Geophysics - Targeting through a blanket of masking sediments
Geophysics - Targeting through a blanket of masking sediments (“cover”) and at depth. Working with a best-available dataset (including geo-knowledge) to test and rank Stawell-like targets under cover. Basalts in the geology focuses gold mineralisation. Geophysics can find the basalts. Footprint of 4
Slide 7: NSM Exploration and discovery focus
NSM Exploration and discovery focus. The 3.6km Darlington-Caledonia trend is a clear priority because of the high-grade gold potential. NSM is exploring for shallow repeats of the multi million-ounce Stawell Mine gold deposit at Stawell – masked and preserved by cover – (SGM)2 within the economic fo
Slide 8: Drilling results targeting Stawell-type basalts and Mariners-type splays
Drilling results targeting “Stawell-type” basalts and “Mariners-type” splays. 5.00m @ 1.21 g/t Au from 56.00m (ASA115) (1) 2.00m @ 2.00 g/t Au from 58.00m (ASA184) Lubeck Tip 1.00m @ 5.05 g/t Au from 56.00m (NSAC0172) (2) NSM 1.00m @ 3.00 g/t Au from 42.00m (NSAC0173) tenements (brown) Interpreted 5
Slide 9: Mariners Historic Mines – High Grade Gold Opportunity
Mariners Historic Mines (the “Mariners-type” model) – High Grade Gold Opportunity. Occurs as splays of mineralisation off (and above) the deeper basalt (and links to deeper “Stawell-type” gold system). The historic high-grade Mariners-type production includes 0.78-0.95Moz Au at 28-30g/t Au1, 2. Basa
Slide 10: Stawell connects to the 3.6km Darlington-Caledonia fairway
Stawell connects to the 3.6km Darlington-Caledonia fairway Darlington is an NSM priority target 6 km north of Stawell, includes newly discovered basalt with potential to form Stawell-type and/or Mariners-type gold mineralisation along an 8km trend from Stawell.

Slide 11: Cross-section through Darlington
Cross-section through Darlington. Geology, structure and mineralisation looks very similar to Stawell-Mariners! NSD058 NSD057 (330m north) Production from the historic Darlington Mine: 2,347oz Au at 18.2 g/t Au4 Cross section through previous drilling at Darlington (NSD057(2), NSD058(3)) discovered
Slide 12: Darlington Target – Mariners-type or Mariners-repeat? (2025)
Darlington Target – Mariners-type or Mariners-repeat? (2025) Darlington includes visible gold (VG)-bearing brecciated quartz-sulphide vein3 and basalts at depth (NSD053(1) and NSD057(2)) – a mineralised ‘splay’ off the basalt at depth == “Mariners Type”. NSD057 – 2.3m at 29.2 g/t Au from 108.2m – is
Slide 13: Darlington – Caledonia trend
Darlington – Caledonia trend. Encouraging results in most recent drilling do not occur in isolation. Multiple high-grade drill intercepts and high-grade historic workings occur over 3.6km trend. Geology, geochemistry and new observations further highlight gold potential. 1.00m @ 12.15 g/t Au from 36
Slide 14: Darlington West – NSD058
Darlington West – NSD058(1) NSD058 is the first hole testing a “blind” target based on geophysics and numerical modelling data. The hole intersected mineralisation on the upper and lower margins of a new, intersected basalt – an exciting result for a possible repeat of the Stawell-type mineralisatio
Slide 15: Programs - current
Programs - current. Follow-up on NSD057 and NSD058 are current priorities for NSM exploration. Surface chemistry/geophysics to understand strike extents of the system. Potential to migrate learnings/techniques to Caledonia (2 km nth). NSD057 NSD058 Darlington Mine Darlington Darlington West fault Ab
Slide 16: Programs – upcoming
Programs – upcoming. IP test-line across Darlington target to understand 3D mineralisation trend? AC follow up on soils results – in the weathered zone (80-90m depth). DD follow up on AC results. IP SURVEY: A proposed (Induced Polarisation geophysics survey (“IP”) has been complicated by access. How
Slide 17: Work Program 2025+
Work Program 2025+ Follow-up on the high-grade shallow target at Darlington. Expand the Darlington targets that “fit” a Stawell-type or Mariners-type mineralisation model. Review Wildwood as a potential satellite deposit. Prepare secondary targets for renewed work. <-- 1st results are good! <-- Dril
Slide 18: Summary
Summary Darlington – and the trend towards Caledonia - with potential for a high-grade gold mineralisation is a priority – and can be ‘transformative’ for gold opportunity north of Stawell (NSM). Current and up-coming programs are focused on evaluation of new high-grade targets north of Stawell. NSM
