Slide 8: Geology
Geology The geology at Stawell includes basalt emplacement (important for controlling later mineralisation) The mineralisation at Stawell is the same ‘event’ as most of Victoria. Geological evolution of western Victoria1 Metallogeny1 Structure2 Miocene HMS-REE 7 400 Ma IRG Orogenic Au Orogenic Au 44
Slide 9: Stawell Gold Mine (the "Stawell-type" model)
Stawell Gold Mine (the “Stawell-type” model) The mine is cored by a buttress of basaltic rock. Gold mineralisation wraps around the basalt margin. Find more basalts == find another Stawell!? Mariners splay Wonga (see next slide) Stawell historic production1: Magdala West 2.67M oz Au (pre-1980) 2.62M
Slide 10: Drilling results target "Stawell-type" basalts
Drilling results target “Stawell-type” basalts Ashens 5.00m @ 1.21 g/t Au from 56.00m (ASA115) 2.00m @ 2.00 g/t Au from 58.00m (ASA184) (1) 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 (yellow) Old Roo Interpreted 5.00m @ 1.06 g/t
Slide 11: Finding basalts (and the related gold systems) through cover
Finding basalts (and the related gold systems) through cover. Working with a best-available dataset (including geo-knowledge) to test and rank Stawell-like targets under cover. Both the established gold models (Stawell-type and Mariners-type) are associated with the basalts. Footprint of 4.9 Moz Au
Slide 12: Project Pipeline
Project Pipeline NSM has a robust project pipeline, based on regional drill programs and geophysics. NSM is focused on the projects that respond best to the model (Wildwood and Darlington). (SGM (4)) Identified and interpreted basalts with potential to host Stawell-type mineralisation 3 Only 30% (of
Slide 13: Wildwood Mineral Resource
Wildwood Mineral Resource1 87,300 oz Au Mineral Resource from immediately below cover (40m depth). Shallow-tested and open in several directions. The Mineral Resource at Wildwood has benefited from re-interpretation and re-estimation and structural interpretation in June 2023 (1) . Indicated Inferre

Slide 15: NSD054 & NSD055 targeted Flank-type mineralisation on Wildwood's east flank
NSD054 & NSD055 targeted Flank-type mineralisation on Wildwood’s east flank Only anomalous gold grades (<1g/t Au) were intersected. However, thick intercepts of the prospective geology with the “right” alteration were intersected in each hole. 8m 11m 19.8m WDD079 - 259.8-271.32 NSD054 218.1 - 236.3m

Slide 17: Darlington
Darlington: 6 km north of Stawell, includes “Mariners-type” above a deeper basalt with potential to form “Stawell-type” gold mineralisation system at depth. Occurs on the Browns basalt trend – demonstrated mineralised over 8km. The northern 3.6km of Browns trend is on NSM ground. Darlington is now i

Slide 19: Darlington target – Stawell+Mariners-type gold potential
Darlington target – Stawell+Mariners-type gold potential NSD057 stepped out 200m south to test the intersection of Darlington trend and the basalt. An encouraging 16m zone of anomalous (>1 g/t Au) was returned on a faulted basalt margin. Visible gold-bearing quartz veining encountered higher in the
Slide 20: Darlington Target – Mariners-type or Mariners-repeat?
Darlington Target – Mariners-type or Mariners-repeat? Darlington, 6 km north of Stawell, includes visible gold (VG)-bearing brecciated quartz-sulphide vein5 and basalts at depth (NSD053(3) and NSD057(5)) – interpreted as a mineralised ‘splay’ off the basalt at depth. NSD057 – 2.3m at 29.2 g/t Au fro
Slide 21: Mariners Historic Mines (the "Mariners-type" model)
Mariners Historic Mines (the “Mariners-type” model) Splays of mineralisation off (and above) the basalt. At Stawell, the historic mining is impressive, with historic production of 0.95Moz Au at 30g/t Au1. Mariners splay Understanding Mariners – particularly as it Magdala East formed a large, high-gr
Slide 22: 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 23: Proposed Work Program 2025
Proposed Work Program 2025. Focus on follow-up on the high-grade shallow target at Darlington, and other Darlington targets that “fit” a Stawell-type or Mariners-type mineralisation model. Review Wildwood as a potential satellite deposit and prepare secondary targets for renewed work. NSM’s project
