HIGHLIGHTS • Strategic acquisition secures additional tenure directly adjacent to the Black Swan Processing Hub • Tenements are positioned across prospective lithologies and key geological structures known to host gold and nickel mineralisation • The Agreement includes key tenement E27/630 immediately north of the Black Swan Processing Hub, directly along strike of the Wilsons Gold Prospect1 and in an area which would facilitate any potential expansion of the current Black Swan infrastructure footprint • The new tenements will increase Maritana’s WA Goldfields tenure by 83.5km2 to 1,235.5km2 • Consideration for the new tenement package comprises $345,000 cash and 509,259 restricted Maritana shares at a deemed issue price of $1.08 per share • Completion of the Agreement is expected in the June 2026 quarter • The new tenements will be incorporated into Maritana’s FY2027 exploration strategy Managing Director and CEO Mr Grant Haywood commented: “This acquisition continues our regional consolidation strategy and secures key additional tenure around our Black Swan Processing Hub. This includes the potential northern extension of the Wilson’s gold anomaly which is located just 200m from the Black Swan infrastructure. The tenure would also facilitate potential extensions and optimisation of the current Black Swan infrastructure in future, if required. This is another important step in the Company’s plan to becoming a significant gold producer in the Goldfields of Western Australia.” 1 Refer to ASX Announcement ASX:POS - “Black Swan Targets Expanded and Remain Open” 11 November 2024 maritanaminerals.com.au Page | 2 TENEMENT AND EXPLORATION POTENTIAL Acquisition of the Nano Metals tenements increases the contiguous tenure of both the Black Swan Processing Hub and the Gordons Project2 as well as improving the exploration potential for current prospects and targets such as Wilson’s (Figure 1).
