# Barksdale Meets Technical Milestones for Phase II Earn-In and Updates SUN26-013R Assay Result of 65.5 Metres of 0.47% Cu and 1.24 g/t Ag, Including 7.6 Metres of 1.93% Cu and 1.96 g/t Ag Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/barksdale-meets-technical-milestones-for-phase-ii-earn-in-and-updates-sun26-013r--261fc2c1-eacb-4685-aed5-b7613e2d61b6 Original source: https://money.tmx.com/en/quote/BRO/news/5536817439546073/barksdale-meets-technical-milestones-for-phase-ii-earn-in-and-updates-sun26-013r Publisher: tmx Original announcement: 2026-07-27T11:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Barksdale Resources Corp. - Ticker: BRO - Exchange: TSX - Region: Arizona - Primary commodity: Copper - Secondary commodities: Silver, Molybdenum - Document categories: Drill results, Agreement transaction - Extracted: 2026-09-15 14:36:15 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Barksdale Resources has met its Phase II earn-in requirements for the Sunnyside property, increasing its ownership to 67.5%. The company also updated assay results for hole SUN26-013R, which now includes high-grade copper and silver intercepts previously omitted due to overlimit values. Reasoning: The company met a major JV milestone and updated a drill hole with higher-than-previously-reported grades due to overlimit assay corrections. - Positive factor: Phase II earn-in milestone met - Positive factor: Increased ownership interest to 67.5% - Positive factor: High-grade copper sub-interval reported - Positive factor: Continuous mineralization suggested over 600m strike - Negative factor: Previous assay results were under-reported due to overlimit values Facts used in scoring: 4 ## 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 details QA/QC protocols including standards, blanks, and duplicates. Evidence · text > comprising 2% certified reference materials or standards, 2% blank material, and 2% field duplicates **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Geologists suggest the holes connect a large zone of mineralization over 600m strike. Evidence · text > likely connect a large zone of copper lode vein mineralization that is continuous over greater than 600m of strike ## Extracted facts Stored fact records: 4.

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.
