Lytton announced that substantial quantities of chrome diopsides
and significant numbers of garnets, chromites and ilmenites were found in eight separate samples taken from the company's two million acre claim block immediately north of the BHP/Dia Met block.
The area was identified on the basis of historic sampling, by the Saskatchewan Geological Survey and the Geological Survey of Canada in the early 1990's that recovered high counts of kimberlite indicator minerals including significant concentrations of pyrope and eclogitic garnets, chrome diopside
and oxides covering a large aerial extent of unglaciated terrain.
To investigate this, probe mounts containing 307 garnet grains and 25 chrome diopside
grains were dispatched to the Euclid Geometrics Laboratory in Kitchener, Ontario, for microprobe analysis.
The detailed chemical analysis of a selection of the positive grains suggests the elevated counts are from one source and confirmed the presence of G10 and G9 and G1 garnet, picroilmenite, forsteritic olivine and chrome diopside
After splitting of these grains to a representative fraction, 40 garnet grains, 12 chrome diopside
grains and 50 ilmenite grains were mounted for electron microprobe analysis:- these are marked as the RC set.
These trains are characterized by varying amounts of fresh (near source) grains of pyrope and eclogitic garnets, chrome diopside
, picroilmenite and olivine contained within glacial deposits.
These include ilmenite, chromite, pyrope garnet and chrome diopside
Dispersed mantle fragments of olivine, pyrope garnet and chrome diopside
indicate each dyke has the potential to host diamonds and testing is warranted" said Mr.
is the most common kimberlite mineral found in the concentrates.
In addition, 85 till samples collected by Geodex on the Lac 1-5 property in 2002 along widely spaced traverse lines yielded a total of 104 pyrope-garnets and 19 chrome diopside
grains from a mineral indicator train in the south-central part of the claims.
These clusters are associated with down-ice kimberlite indicator minerals including G-10 pyrope garnet, G9 pyrope garnet, picroilmenite, chrome spinel with diamond inclusion chemistries, chrome diopside
and kimberlite olivine.
One sample contained mainly grantic and the other mainly volcanic components yet both showed fresh single grains of chrome diopside
