# Black Mammoth Metals Samples up to 717 g/t Silver with 210 g/t Average at Amador, NV Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/black-mammoth-metals-samples-up-to-717-g-t-silver-with-210-g-t-average-at-amador--fbbed1c2-f1b8-453a-9af3-c4b855d65a90 Original source: https://money.tmx.com/en/quote/BMM/news/5982169262111560/black-mammoth-metals-samples-up-to-717-g-t-silver-with-210-g-t-average-at-amador Publisher: tmx Original announcement: 2025-07-22T13:15:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Black Mammoth Metals Corporation - Ticker: BMM - Exchange: TSX - Region: Nevada - Primary commodity: Silver - Secondary commodities: Arsenic, Antimony, Selenium - Document categories: Drill results - Extracted: 2026-08-21 07:45:23 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Black Mammoth Metals reported high-grade silver rock chip samples at the Amador property in Nevada, with grades averaging 210.3 g/t Ag and peaking at 717 g/t Ag. The program included 19 samples and confirmed the presence of silver mineralization within a quartz vein shear, alongside elevated arsenic levels. Reasoning: High-grade silver rock chip samples \(up to 717 g/t\) confirm historical potential, supported by robust QA/QC and QP sign-off, though arsenic levels are elevated. - Positive factor: High grade silver intercepts - Positive factor: QA/QC disclosed - Positive factor: QP signed - Negative factor: Deleterious elements present - Negative factor: Sample type is rock chip Facts used in scoring: 3 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 717 g/t silver is exceptionally high grade. Evidence · text > ranging from 1.7 g/t to 717 g/t **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 ALS laboratory, accreditation, and specific QA/QC methods like standards and blanks. Evidence · text > Black Mammoth Metals Corp's QA/QC program includes regular insertion of CRM standards, duplicates and blanks **Deleterious Elements Present** Polarity: negative Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release. Why it applies: Arsenic, antimony, and selenium were explicitly reported. Evidence · text > accompanied by strong trace element contents with As up to 3350 ppm ## Extracted facts Stored fact records: 3.

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.
