Slide 6: Project Overview
6 Project Overview ▪ Within 50km of Northern Star’s Yandal Operations Centre. ▪ >70km of prospective greenstone belt. ▪ Current resource base spans 3km of strike, >60km remaining largely untested. ▪ Only 26% of historic drilling reaches depths greater than 100m. ▪ 400koz Mineral Resource Estimate.1
Slide 7: Key Target Areas
7 Key Target Areas Priority regional target zones have potential for major discoveries ▪ Great Western ▪ Mustang ▪ Dusk ‘til Dawn
Slide 8: Great Western
8 Great Western High priority splay corridor with gold anomalism untested by drilling ▪ Drilling by previous holder targeted the intrusion itself – no follow up. ▪ Extremely strong Mo-Bi-Te anomalism remained unexplained. ▪ Mafic-intermediate contact. ▪ Significant structural complexity – intersecti
Slide 9: Great Western
9 Great Western High priority splay corridor with gold anomalism untested by drilling ▪ GML soil sampling and lag sampling identified key gold trends.1 ▪ Follow-up prospecting activities have returned over 100 gold nuggets around the margin of the Great Western Intrusion.2 Mafic-Intermediate Contact
Slide 10: Great Western
10 Great Western Confirmation of significant gold mineralisation Cautionary Statement: Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also po

11 Key Target Areas Priority regional target zones have potential for major discoveries ▪ Great Western ▪ Mustang ▪ Dusk ‘til Dawn
Slide 12: Mustang
12 Mustang Analogous Horse Well camp identified at Mustang ▪ Multielement geochemistry by GML accurately mapped key lithologies. ▪ Same contact position immediately to the south hosts high grade mineralisation. ▪ Historic BOH +0.1g/t Au identified in old RAB and aircore drilling – not followed up in
Slide 13: Mustang
Mustang 13 Large Scale Emerging Gold System ▪ Aircore drilling highlighting an emerging, extensive gold system. ▪ Multiple areas requiring tighter-spaced follow-up drilling. ▪ First significant discovery – Haflinger: 52m @ 1.4g/t Au.1 ▪ New prospect at Hummer: 16m @ 1.0g/t Au.2 ▪ Drilling coming int
