He’s still a bit upset about it, bless him.
One sample recovered 90,000 cpt :-) not cpht !!
Diamondiferous Group A eclogites constitute a minor portion of the mantle-derived xenoliths in the eastern Finland kimberlites. They have been derived from the depth interval 150–230 km where they are inferred to occur as thin layers or small pods within coarse-grained garnet peridotites. The chemical and isotopic composition of minerals suggest that they represent (Proterozoic?) mantle-derived melts or cumulates rather than subducted oceanic lithosphere. During magma ascent and emplacement of the kimberlites, the eclogite xenoliths were mechanically and chemically rounded judging from the types of surface markings. In addition, those octahedral crystal faces of diamonds that were partially exposed from the rounded eclogite xenolith became covered by trigons and overlain by microlamination due to their reaction with the kimberlite magma. The diamonds bear evidence of pervasive plastic deformation which is not, however, evident in the eclogite host. This suggests that annealing at ambient lithospheric temperatures has effectively recrystallised the silicates while the diamond has retained its lattice imperfections and thus still has the potential to yield information about ancient mantle deformation. One of our samples is estimated to contain approximately 90,000 ct/ton diamond implying that some diamonds occur within very high-grade pods or thin seams in the lithospheric mantle. To our knowledge, this is one of the most diamondiferous samples described.
The drill went in the wrong angle from the past owners i believe and recovered far too much country rock.
Had the degrees been drilled different and so would the outcome ?? kimberlite not country rock ,country rock holds no diamonds ,corrected me if that's wrong. ?
Why was Mr Grimmer so keen to get his hands on this if not commercial, says it all really !!!
it is clear that the distinction between the main rock types is due to secondary alteration, and that the most important geological diamond grade control in Lahtojoki kimberlite is country rock xenolith dilution.
Robemy CONroys pet pumper
Lol Grimmer / Commin / whatever.
It was uneconomical because the initial samples included too much country rock, excavated the wrong part - do some proper research.
All the the results Kdr publish are not their findings they are from the failed efforts of the joint-venture, mantle/kopane undertook with the Lahtojoki project. Extraction of a representative 5,500 tonne bulk sample are complete and Mantle commenced the The bulk sample approximately 3,500 tonnes of surface excavated ore and 2,000 tonnes of ore recovered from a large diameter Bauer drilling rig. Mantle commissioned the construction of a 10 tonnes per hour mobile DMS plant. The project failed after half the bulk sampling results were not economically viable to gain further funding. Fast forward 13 years and KDR are pretending this is a new project with no mention of the failed efforts by more than one exploration company with much more spending power than CONroys bucket and spade
29% holding TRI 1 above 3% holder's
18.91% directors.
18% from last placing still on the QT .
66% in sticky hands of the company.
Could work out al least a further 10% on private shareholders
Now show us the missing 18% from last placing.
Try company register?!
Why research if you don't hold here.
Very Odd or sad.
Commin or Going?

Neat!!
Lahtojoki kimberlite in Finland. ... diamondiferous but uneconomical when considered in isolation.
