# Spartan Metals Reports Significant Silver-Antimony-Copper Assays with Grades up to 1,927 g/t Ag, 0.67% Sb, and 1.83% Cu from Past Producing Antelope Mine, Nevada Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/spartan-metals-reports-significant-silver-antimony-copper-assays-with-grades-up--6f110d1a-9c8b-4197-afbc-1a068a8f4af2 Original source: https://money.tmx.com/en/quote/W/news/6382761334529162/spartan-metals-reports-significant-silver-antimony-copper-assays-with-grades-up- Publisher: tmx Original announcement: 2026-06-25T09:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Spartan Metals Corp. - Ticker: W - Exchange: TSX - Region: Nevada - Primary commodity: Silver - Secondary commodities: Antimony, Copper, Arsenic - Document categories: Drill results, Other - Extracted: 2026-09-15 06:41:16 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Spartan Metals has reported high-grade silver, antimony, and copper assays from the Antelope Mine in Nevada, with silver grades reaching 1,927 g/t. Surface sampling identified a mineralized footprint of approximately 1.3 km by 0.6 km, a substantial expansion over the historical 50-meter strike length. Reasoning: High-grade silver and copper assays from surface sampling and backpack drilling significantly expand the known mineralized footprint at the Antelope Mine. - Positive factor: High-grade silver intercepts exceeding 1,000 g/t - Positive factor: Significant lateral extension of mineralized footprint \(1.3 km vs 50 m\) - Positive factor: Presence of strategic critical mineral antimony - Positive factor: QA/QC protocols disclosed with certified lab - Negative factor: True width not yet determined - Negative factor: Drilling is limited to small-diameter backpack core Facts used in scoring: 6 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Silver grades up to 1,927 g/t Ag are exceptionally high. Evidence · text > Grades up to 1,927 g/t Ag **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 mentions American Assay Lab \(AAL\) as a certified lab and details QA/QC methods like CRM standards and duplicates. Evidence · text > AAL undertakes its own internal coarse and pulp duplicate analysis **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Surface sampling defined a footprint 1.3 km long, much larger than the historical 50m mine extent. Evidence · text > significantly larger than the existing mine extent which produced along strike of approximately 50 meters ## 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.
