The program intersected widespread, strongly elevated radioactivity, including several high-grade intercepts that extend the known footprint of the Hurricane deposit. Reasoning: The summer drilling program intersected widespread and some of the strongest radioactivity to date along the Hurricane South Trend, including significant step-out hits east and west of previous mineralization. - Positive factor: strong radioactivity intersected - Positive factor: step-out extension along strike - Positive factor: widespread mineralization - Negative factor: geochemical assays pending Facts used in scoring: 10 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: LE26-250 and LE26-254 intersected radioactivity outside the existing Hurricane footprint. Evidence · text > LE26-250, drilled 75 m east of LE26-248 and outside the existing Hurricane footprint, intersected 11,075 cps **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 mentions data verification procedures including comparing RS-125 spectrometer data with 2PGA probe and core photos. Evidence · text > Data verification procedures included comparing radioactivity measured on core with the RS-125 spectrometer to radioactivity measured downhole with the 2PGA probe **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a mill\_cil route \("CIP"\) ## Extracted facts Stored fact records: 10.

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.
