- CleanTech outlined an initial eight-hole, roughly 9,000-foot diamond-drill program at Campbell-Crotser, with an option to expand to 16 holes and about 18,000 feet.
- The program was designed to test a previously drilled vein system at roughly 200-foot spacing and support engineering work for an initial underground mine plan and feed for a planned 500-ton-per-day flotation plant.
- The company said this would be the first drilling at Campbell-Crotser since work by Cerro Corporation in the 1970s.
The development
CleanTech announced an initial eight-hole diamond-core program totaling approximately 9,000 feet at its Campbell-Crotser fluorspar project in Kentucky, with potential expansion to 16 holes and roughly 18,000 feet.
The program was designed to test a previously drilled vein system at roughly 200-foot spacing and support engineering work for an initial underground mine plan and feed for a planned 500-ton-per-day flotation plant.
The June 12 source set August 1, 2026 as the scheduled drilling start and January 2027 as the target for completing the initial program. Because the release described a future start date, this report does not claim physical drilling had commenced on June 12.
CleanTech also cautioned that the historical exploration target and resource references were not current mineral resources and that further work was required.
Why this matters
Modern drilling is needed to replace reliance on decades-old information and provide data suitable for mine planning and resource work.
The practical significance depends on follow-through in later filings, technical reports or operating updates rather than the announcement alone.
Industry and company context
The company said this would be the first drilling at Campbell-Crotser since work by Cerro Corporation in the 1970s.
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. The company said this would be the first drilling at Campbell-Crotser since work by Cerro Corporation in the 1970s.
Readers should separate completed actions from targets, proposed transactions, management expectations and other forward-looking statements.
Execution and risk considerations
The targeted quantity and grade remain conceptual until sufficient drilling supports a current mineral resource, and the planned start or completion dates can change.
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
- Confirmation of physical drill mobilization.
- Core recoveries, assays and true-width interpretation.
- Whether the program expands beyond eight holes.
- Integration of drilling into the mine and plant permit packages.
Cornerstone perspective
Modern drilling is needed to replace reliance on decades-old information and provide data suitable for mine planning and resource work. 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 12, 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.
