Minestarters Atlas analysis
Summary
Aztec Minerals reported high-grade silver and gold drill results at the Tombstone Project in Arizona, highlighted by a 253 g/t silver intercept in hole TR25-03. The company has also mobilized a second drill rig to target deeper carbonate replacement deposit (CRD) mineralization.
Reasoning: The drill hole TR25-03 returned an exceptional silver grade of 253 g/t over 6.08m, significantly exceeding typical thresholds and demonstrating continued discovery potential.
Positive factors
- high-grade silver intercept
- extension of known mineralization
- new drill rig mobilization
Negative factors
- apparent widths only
Facts used in scoring: 12
Classification and evidence
Bonanza Interceptpositive
Exceptionally high-grade zone, well above the deposit-type norm.
Why it applies: 253 g/t silver is exceptionally high grade for this deposit type.
Evidence · text
“253.0 grams per tonne (gpt) silver”
Apparent Width Onlynegative
Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.
Why it applies: The company explicitly states that all intersection lengths reported are apparent widths, not true widths.
Evidence · text
“all intersection lengths reported are apparent widths of the mineralization, not true widths”
QA/QC Disclosedpositive
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: The release mentions the use of certified blanks, standards, and duplicates.
Evidence · text
“All holes contain certified blanks, standards, and duplicates as part of the quality control program.”

Reasoning: Expanded from assay table. 2.26 g/t gold is strong against the open_pit mining band [5, 2, 1, 0.3] g/t. Grade×width 13.8 g/t·m is weak (grade alone is strong; the better of the two is used).
Positive factors
- 2.26 g/t gold is strong on the open_pit mining band.
Negative factors

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.
