Step-out drilling has successfully identified multiple parallel mineralized shear zones, extending the target's strike potential. Reasoning: Initial discovery holes at the Dumbwa target confirmed significant copper mineralization in shear zones, with step-out drilling extending the strike and confirming structural continuity. - Positive factor: significant copper mineralization confirmed - Positive factor: continuous copper sulphides observed for over 150m - Positive factor: step-out holes confirmed multiple parallel shear zones - Positive factor: QA/QC protocols and accredited lab disclosed - Negative factor: apparent width only \(true width not stated\) Facts used in scoring: 6 ## 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: Release includes details on in-house QA/QC program, including blanks, standards, and duplicates, and uses an accredited laboratory \(SGS\). Evidence · text > Midnight Sun follows an in-house QA/QC program that consisted of a random insertion every 10 th sample of either a coarse blank, fine blank, coarse duplicate, fine duplicate, or Certified Reference Material \(standards\). **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: Intervals are reported as downhole widths without true width or drill orientation provided for the specific intercepts. Evidence · text > Intervals listed are based on drilling intervals and therefore are considered relative rather than true widths. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Step-out holes DBW-25-009 and DBW-25-010 confirmed the presence of multiple parallel shear zones and extended the known mineralization. Evidence · text > The two step-out holes confirmed the presence of multiple parallel shears zones and their near vertical orientation. ## 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.
