Minestarters Atlas analysis
Summary
Black Mammoth Metals has reported high-grade silver results from rock chip sampling at the West Reveille property in Nevada, with intercepts reaching up to 2,610 g/t Ag. The mineralization is associated with base metals (Pb, Zn, Cu) and includes elevated arsenic and antimony levels.
Reasoning: The release reports exceptionally high-grade silver from rock chip sampling, supported by base metal presence and robust QA/QC disclosure, though penalty elements are present.
Positive factors
- High-grade silver intercept of 2,610 g/t
- Presence of base metal concentrations (Pb, Zn, Cu)
- QA/QC protocols disclosed including ISO accredited lab and CRM/blanks/duplicates
- QP sign-off provided
Negative factors
- Deleterious elements (arsenic and antimony) noted
Facts used in scoring: 1
Classification and evidence
Bonanza Interceptpositive
Exceptionally high-grade zone, well above the deposit-type norm.
Why it applies: 2,610 g/t silver is exceptionally high-grade.
Evidence · text
“Samples up to 2,610 g/t Silver”
QA/QC Disclosedpositive
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: The release details the use of CRM standards, duplicates, blanks, and ISO 17025 accredited ALS laboratory.
Evidence · text
“Black Mammoth Metals Corp's QA/QC program includes regular insertion of CRM standards, duplicates and blanks”
Deleterious Elements Presentnegative
A source-stated penalty, refractory or recovery concern in the fact's scope. Element detection alone, including measured elements explicitly below penalty thresholds, does not trigger this tag. Respect negation and retain a separately stated concern even when another risk is explicitly absent.
Why it applies: Elevated arsenic and antimony concentrations were reported.
Evidence · text
“elevated pathfinder elements (arsenic up to 1,360 ppm and antimony up to 3,110 ppm)”

Tags used in scoring
QA/QC Disclosedpositive
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: qaqc_disclosed is true
Cut-off Undisclosednegative
High-grade interval reported without stating the cut-off grade used for compositing.
Why it applies: no cutoff_grade was stated
Deleterious Elements Presentnegative
A source-stated penalty, refractory or recovery concern in the fact's scope. Element detection alone, including measured elements explicitly below penalty thresholds, does not trigger this tag. Respect negation and retain a separately stated concern even when another risk is explicitly absent.
Why it applies: deleterious_flag is true
How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
