The update reports a Measured and Indicated resource of 15.3 million tonnes at 1.99 g/t gold, representing a 34% grade improvement and 35% increase in contained ounces compared to the 2012 estimate. Reasoning: Significant upgrade of the Magambazi resource from 2012 levels, with substantial improvements in grade, tonnage, and contained ounces, alongside a category upgrade from Inferred to M&I. - Positive factor: Category Upgrade - Positive factor: Tonnage Growth - Positive factor: Grade Improvement - Positive factor: Contained Metal Growth - Positive factor: QP/CP Signed Facts used in scoring: 1 ## Classification and evidence **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: The bulk of the inferred resource in 2012 has been upgraded to the measured and indicated category. Evidence · text > The bulk of the inferred resource in 2012 mineral resource estimate has been upgraded to the measured and indicated category **Grade Improvement** Polarity: positive Definition: Average resource grade improved vs prior estimate — better deposit economics. Why it applies: The new estimate represents a 34% improvement on grade over the 2012 calculation. Evidence · text > representing a 34% improvement on grade **Contained Metal Growth** Polarity: positive Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes. Why it applies: The update shows a 35% improvement in contained ounces over the 2012 calculation. Evidence · text > and a 35% improvement of ounces over the 2012 calculation **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: Andrew Lee Smith, P.Geo., has reviewed and approved the technical contents. Evidence · text > Andrew Lee Smith , P.Geo., C.E.O., a Qualified Person under the definitions of National Instrument 43-101, has reviewed and approved **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: The update was completed in accordance with JORC standards. Evidence · text > The update of the 2012 resource in accordance with JORC standards was completed by Geofields Tanzania Limited ## Extracted facts Stored fact records: 1.

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.
