Analysis by Minestarters Atlas
Minestarters Atlas analysis
Summary
Black Bear Minerals' re-assay program at the Shafter Silver Project in Texas has returned significantly higher silver grades than historic results, including an intercept of 9.1m at 1043g/t Ag. The modern multi-element testing is also uncovering gold, lead, and zinc potential that was largely absent from previous datasets.
Reasoning: Re-assaying of historic core is yielding significantly higher silver grades and uncovering previously unquantified gold and base metal potential, supporting a future maiden JORC resource.
Positive factors
- higher silver grades than historic assays
- identification of additional polymetallic potential (Au, Pb, Zn)
- re-assays increasing contained metal
Negative factors
- results are re-assays of historic core, not new drilling
- analytical method changes (4-acid vs 2-acid) may bias comparison
- historical data not JORC compliant
Facts used in scoring: 5
Classification and evidence
Bonanza Interceptpositive
Exceptionally high-grade zone, well above the deposit-type norm.
Why it applies: 0.6m at 2990g/t silver is exceptionally high grade.
Evidence · text
“including 0.6m at 2990g/t”
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 modern multi-element testing and QAQC procedures.
Evidence · text
“new samples are analysed using modern techniques and QAQC procedures”
Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: The existing resource is described as a foreign estimate that has not yet been classified under JORC.
Evidence · text
“A competent person has not completed sufficient work to classify the foreign estimate as a Mineral Resource under the JORC Code 2012”

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.
