RE: What we know we have in Kuhmo29 Apr 2026 05:56
The mine was the first successful commercial non alluvial diamond mine not located on a kimberlite pipe. The pipe is named "AK-1", although it is commonly simply called the "Argyle pipe".
The volcanic pipe is a diatreme, composed of olivine lamproite, present as tuff and lava. Peripheral volcanic facies suggest the lamproite eruption formed a maar. At the margins of the volcanic pipe the lamproite is mixed with a volcanic breccia containing shattered wall rock fragments mixed and milled by the eruption. Minerals in the marginal facies include zeolite minerals, micas, kaolinite and clays, typical of post-eruption hydrothermal circulation.
Ring any bells ?
INITIAL REVIEW INDICATES POSITIVE RESULTS FROM DRILLING AT ANOMALY 5
• Winter drilling programme completed at Anomaly 5 diamond target, Kuhmo, Finland
• Probable olivine lamproite breccia intersected in two drillholes
• Diagnostic rock types in drill core indicate proximity to olivine lamproite intrusive complex
