Summary
CleanTech has engaged a permitting specialist to begin the application process for the Campbell-Crotser underground fluorspar mine and flotation plant in Kentucky. The announcement also includes a restatement of a 1974 historical mineral resource estimate, which the company explicitly warns is non-compliant with modern CIM standards and should not be relied upon.
Reasoning: The company is advancing the permitting stage for a fluorspar project, supported by historical resource data that is noted as unreliable and non-compliant with current standards.
Positive factors
- Initiation of permitting process for Campbell-Crotser project
- Engagement of specialized permitting expert
- Presence of significant historical fluorspar mineralization
Negative factors
- Historical resource estimate is non-compliant with modern standards
- Lack of documented estimation methodology or QA/QC for historical data
- Resource categories predate current CIM standards
Low confidence — this extraction should be reviewed alongside the original source.
Facts used in scoring: 6
Classification and evidence
Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: The historical estimate includes an Inferred category which the company notes is not defined by current CIM standards.
Evidence · text
“Inferred 160,724 35.97 3.75 1.25”
Historical Estimate Onlynegative
Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling.
Why it applies: The resource estimate is from a 1974 report and does not comply with current NI 43-101 or CIM standards.
Evidence · text
“A historic (non-43-101 compliant) mineral resource estimate performed by Boyce Moodie III in 1974”
No QA/QC Disclosurenegative · Story-specific tag
Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.
Why it applies: The company explicitly states the historical estimate lacks documented QA/QC protocols.
Evidence · text
“absence of QA/QC protocols”

Context: 645,117
Tags used in scoring
Indicated Resourcepositive
Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.
Why it applies: category is "indicated"
Cut-off Undisclosednegative
High-grade interval reported without stating the cut-off grade used for compositing.
Why it applies: no cutoff_grade was stated
No Contained Metalnegative
Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.
Why it applies: contained_metal was not reported
Stale Estimatenegative
Effective date is >2 years old — data currency concern, may not reflect current geological understanding.
Why it applies: effective date is 52.5 years before this release

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.
