MGU - MAGNUM MINING AND EXPLORATION LIMITED
Investment Thesis
Southern China-style IAC system with encouraging attributes: near-surface mineralisation (0–15m auger depth), mild ammonium-sulphate desorption rates of 22–63% D-TREO unoptimised, and a meaningful MREO fraction with repeated Tb+Dy signals up to 33ppm D-TbDy — the critical magnet-metal differentiator. However, all holes are shallow verticals (avg ~10m), most terminated in mineralisation meaning true vertical extent is unknown, and 116km² geophysical footprint is a thorium radiometric proxy only — not drill-defined mineralisation.
What No One Else Is Seeing

Fair Value Assessment
No resource exists, so valuation is speculative — but applying US$2–4/t TREO in-situ to a conservative 50Mt scenario at ~800ppm TREO (plausible given 122-hole consistency) yields implied value of A$20–55M vs A$16M market cap. Key re-rating catalyst is the August Exploration Target, which will define tonnage and HREO basket value for the first time.
Key Concerns
Brazil jurisdiction, no vertical depth control (diamond rig just mobilised — holes end in mineralisation), desorption tests are unoptimised screening only (not recoveries), MREO/HREO basket fraction unquantified at system scale, and 116km² footprint is radiometric reinterpretation with no new survey data.

Genuine IAC discovery with the right hallmarks — shallow, desorbable, magnet-REE present — but you're buying the drill bit, not a resource, and Brazil IAC remains unproven
