TAT - TARTANA MINERALS LIMITED
Investment Thesis
Chillagoe skarn/carbonate-hosted polymetallic system with real district-scale optionality across Cu, Au, Ag, Sb — however the gold resource grades (0.25–0.31 g/t Au at 0.1 g/t cutoff) are marginal bulk-tonnage territory with no clear low-cost mining scenario established. The trigger for this announcement is regulatory — forced amendments to retract unqualified mineralisation images and a statement misread as a production target, which is a compliance red flag.
What No One Else Is Seeing

Also: 19m @ 1.30 g/t Au (MMRC050), 24.4m @ 2.04% Cu (DD10 — historical). Resource: ~1 Moz Au @ 0.25–0.31 g/t (Inferred, 0.1 g/t cutoff); 45,000t Cu; 39,000t Zn — all Inferred/Indicated, dated Feb 2023

Fair Value Assessment
1 Moz Au Inferred @ A$30–50/oz in-situ grassroots multiple = A$30–50M implied Au alone, but resource quality (sub-0.3 g/t cutoff, all Inferred, no PFS, no metallurgy defined) discounts this heavily to A$5–9M realistic. Catalysts are 2026 drilling program and copper sulphate cashflow; risks are capital burn vs A$7M market cap.
Key Concerns
Forced corporate presentation retraction (compliance breach), all gold resources at marginal 0.25–0.31 g/t with no metallurgical studies, historical intercepts not JORC 2012 compliant, Competent Person is the Managing Director (conflict of interest), and copper sulphate production declining in 2H CY2025.

A compliance-triggered amendment masquerading as a re-release — the underlying asset has genuine polymetallic complexity but sub-economic gold grades, dated resources, and a regulatory stumble make this a show-me story at current market cap.
