These results confirm the continuity of high-grade mineralisation and represent the longest downhole intersection recorded at the prospect to date. Reasoning: The announcement reports significant new high-grade lithium intercepts at the Blackbeard prospect, including a record-length intersection in NMRD104 that confirms continuity of mineralisation. - Positive factor: thick high-grade lithium intersections - Positive factor: longest downhole intersection at Blackbeard to date - Positive factor: confirms continuity of high-grade mineralisation - Positive factor: step-out/along-strike continuity demonstrated - Negative factor: partial results for NMRD108 - Negative factor: low-grade/no significant intercepts in deep holes NMRD101 and NMRD102 Facts used in scoring: 6 ## Classification and evidence **True Width Disclosed** Polarity: positive Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: NMRD104 reports an estimated true thickness of approximately 45m. Evidence · text > estimated true thickness is approximately 45m **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 release details sampling techniques, laboratory \(Intertek\), and use of standards and blanks. Evidence · text > Intertek utilise standard internal quality control measures including the use of Certified Lithium Standards and duplicates/repeats. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: NMRD104 is located 80m up-dip of a previously reported intersection, confirming continuity. Evidence · text > located approximately 80m up-dip of the previously reported 63m @ 1.67% Li2O in NRC2691, confirming continuity ## Extracted facts Stored fact records: 6.

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.
