GSN - GREAT SOUTHERN MINING LIMITED
Investment Thesis
Golden Boulder sits on the same NW structural corridor hosting >3Moz of defined deposits (Rosemont, Baneygo, Ben Hur) — orogenic shear setting is geologically credible with surface workings confirming continuity. Amy Clarke's 4.7km strike with near-surface oxide intercepts and proximity to Garden Well mill adds near-term optionality; Edinburgh Park's Mt Dillon lithocap/IP anomaly is genuinely high-risk, high-reward porphyry/HS epithermal speculation backed by Gold Fields' $15M earn-in commitment.

Fair Value Assessment
At A$40/oz advanced-exploration multiple, 500koz potential across WA tenements (conservative given 8km+ of combined defined strike) implies ~A$20M WA alone; Edinburgh Park JV retains 25% of a target the market is ignoring — combined fair value A$60–90M vs A$26M market cap. Key catalyst: Golden Boulder/Amy Clarke RC results (July–Aug 2026) and Mt Dillon diamond drill results (Q3 2026).
Key Concerns
All WA intercepts are shallow RC (<100m), true widths unconfirmed, nuggetty high-grade intervals dominate best hits — potential for grade discontinuity at depth; Mon Ami resource is 5 years old and small; 11.1B shares on issue creates dilution headwind at $0.022.

|---|---|
| Near-term | Pending drill results / assays |
| Medium-term | Resource estimate update |
Three drill programs running simultaneously across genuinely prospective Laverton ground, with a major porphyry wildcard backed by Gold Fields — heavily undervalued if even one target delivers continuity at depth
