- CleanTech retained permitting specialist Michael Heim and began preparing separate Kentucky applications for an underground fluorspar mine and a planned flotation plant.
- The company described separate permit applications to Kentucky regulators for an initial underground mine and for a planned 500-ton-per-day flotation plant intended to produce 97% CaF2 acid-grade fluorspar.
- Permitting schedules change as engineering packages and regulator requirements are refined; the July update is the more current timing reference.
The development
CleanTech announced the start of permitting work for its Campbell-Crotser fluorspar project in Kentucky and said it retained Michael Heim to manage the process.
The company described separate permit applications to Kentucky regulators for an initial underground mine and for a planned 500-ton-per-day flotation plant intended to produce 97% CaF2 acid-grade fluorspar.
The June release initially described an end-2026 application timetable and an expected decision window after filing. CleanTech's later July 7 update superseded that timetable with a targeted permit submission by the end of November 2026 and a state decision during the first half of 2027.
This backfill report preserves the June milestone while directing readers to the later permitting update for the current schedule.
Why this matters
Beginning permit preparation moved Campbell-Crotser from exploration planning toward a defined regulatory workstream.
The practical significance depends on follow-through in later filings, technical reports or operating updates rather than the announcement alone.
Industry and company context
Permitting schedules change as engineering packages and regulator requirements are refined; the July update is the more current timing reference.
This article was added during the August 6, 2026 archive review and preserves the announcement date so the $CTV timeline remains chronological.
How to evaluate the update
The core facts to evaluate are the quantified terms, dates and conditions disclosed in the source. Permitting schedules change as engineering packages and regulator requirements are refined; the July update is the more current timing reference.
Readers should separate completed actions from targets, proposed transactions, management expectations and other forward-looking statements.
Execution and risk considerations
Permit applications can be delayed, modified or denied, and a permitted mine plan would still require financing, construction and successful commissioning.
Forward-looking statements, estimates and management expectations can change; readers should use later company filings and technical disclosure for current status.
What to watch next
- Submission of the mine and plant permit applications.
- Kentucky regulator feedback and information requests.
- Engineering changes to the 500-tpd plant plan.
- Alignment between drilling results and the proposed mine design.
Cornerstone perspective
Beginning permit preparation moved Campbell-Crotser from exploration planning toward a defined regulatory workstream. The most useful evidence now is the next verifiable milestone rather than the headline in isolation.
Cornerstone will treat later source documents as controlling where they supersede the June 16, 2026 disclosure.
Source review
This report was checked against the linked primary issuer, newswire or regulatory source and independently cross-checked against a second public-market, newswire or regulatory record during the August 6, 2026 editorial review.
Figures, dates, transaction status and forward-looking conditions are stated conservatively; later disclosure controls where it supersedes the original announcement.
