The company also reported a net profit for the year, largely driven by a non-dilutionary $4 million cash injection from the sale of the Southern Star deposit to Regis Resources Ltd. These results, combined with ongoing drill programs and strategic partnerships, position the company for continued growth in the gold exploration sector. Reasoning: Great Southern Mining Limited's Annual Report for FY2026 highlights significant exploration success with strong gold drill intercepts at its Duketon Gold and Mon Ami projects, extending known mineralization. The company also reported a net profit driven by a strategic asset sale, providing non-dilutionary funding and positioning it for future growth, despite some projects remaining early-stage and the Mon Ami resource estimate being historical. - Positive factor: strong\_drill\_results - Positive factor: mineralization\_extension - Positive factor: non\_dilutionary\_funding - Positive factor: strategic\_partnership - Positive factor: positive\_financial\_performance - Positive factor: upcoming\_news\_flow - Negative factor: stale\_resource\_estimate - Negative factor: inferred\_resource\_component - Negative factor: early\_stage\_projects - Negative factor: combined\_grade\_ambiguity Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 82 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The report states that exploration results are based on information compiled and/or reviewed by Mr Matthew McCarthy, a Competent Person as defined by the JORC Code \(2012\). Evidence · text > The information in this report that relates to exploration results at the Duketon Gold Project, East Laverton Project, Mon Ami Gold Project and Edinburgh Park Project is based on, and fairly represents, information and supporting documentation compiled and/or reviewed by Mr Matthew McCarthy. Mr McCarthy is an employee of Great Southern Mining Limited. He has sufficient experience relevant to the assessment and of this style of mineralisation to qualify as a Competent Person as defined by the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves – The JORC Code \(2012\)”. **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: Mr Matthew McCarthy, an employee of Great Southern Mining Limited, is identified as a Competent Person under JORC Code \(2012\) and has compiled/reviewed the exploration results. Evidence · text > The information in this report that relates to exploration results at the Duketon Gold Project, East Laverton Project, Mon Ami Gold Project and Edinburgh Park Project is based on, and fairly represents, information and supporting documentation compiled and/or reviewed by Mr Matthew McCarthy. Mr McCarthy is an employee of Great Southern Mining Limited. He has sufficient experience relevant to the assessment and of this style of mineralisation to qualify as a Competent Person as defined by the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves – The JORC Code \(2012\)”. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling at Golden Boulder extended known mineralization by ~2km to a strike length of approximately 3.5km, and Mon Ami drilling returned significant extensional results down dip and down plunge. Evidence · text > As a result of this RC drilling program, gold mineralisation was extended by ~2km to a strike length of approximately 3.5km. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The late-2025 drilling program at Golden Boulder included infill drilling, working towards a maiden JORC Mineral Resource. Evidence · text > Infill and extensional drilling, working towards a maiden JORC Mineral Resource in the northern 650m of the prospect. **Stale Estimate** Polarity: negative Definition: Effective date is >2 years old — data currency concern, may not reflect current geological understanding. Why it applies: The Mineral Resource estimate for the Mon Ami Gold Project is from 2021, making it over two years old at the time of this 2026 annual report. Evidence · text > The 2021 Mineral Resource estimate for the Mon Ami Gold Project is shown below. **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The Mon Ami Gold Project Mineral Resource includes an Inferred category component of 0.15 Mt at 0.61 g/t Au for 3,000 Oz Au.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
