The drilling has delineated a second underground shoot and confirmed significant down-plunge continuity, supporting potential resource growth. Reasoning: Strong high-grade gold intercepts at depth that extend both the central zone and a second shoot, increasing resource potential. - Positive factor: high-grade intercepts - Positive factor: extension of mineralization at depth - Positive factor: delineation of a second underground shoot - Positive factor: true width disclosed Facts used in scoring: 4 ## Classification and evidence **True Width Disclosed** Polarity: positive Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: Multiple intercepts explicitly state estimated true width. Evidence · text > true width of 6.3 meters **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling has extended the central mineralized zone 150m and the lower shoot 200m down plunge. Evidence · text > extends the central mineralized zone a further 150 meters down plunge ## Extracted facts Stored fact records: 4. Some facts used in scoring do not have a stored record. ## Drill Results (4) ### SGRD2460 [Link to this fact](https://atlas-staging.minestarters.com/news/fortuna-expands-high-grade-mineralization-at-sunbird-se-gue-la-mine--798bad33-189c-4df0-9d84-d7fe8d42672a#fact-drill-facts-0) Sunbird Deposit, Séguéla Mine · gold #### Identity - Hole ID: SGRD2460 - Project: Sunbird Deposit, Séguéla Mine - Commodity: gold - Region: côte d’ivoire - Reported Region: côte d’ivoire - Ticker: FSM #### Geometry - Grade: 5.2 - Grade Unit: g/t - Intercept: 6.3 m - True Width: 6.3 m - From: 787 m - To: 793.3 m - Intercept Depth: 787 m #### Classification - Deposit Type: other - Program: resource - Sample Type: drill - Group ID: SGRD2460:787-793.3 - Mining Method: underground #### Location - Location: Sunbird - Loc.

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.
