Ontario - RJK Explorations Ltd ('RJK' or 'the Company') (TSX-V: RJX.A, US OTC: RJKAF) has received results from CF Mineral Research in Kelowna BC, from seven large-tonnage, on-surface kimberlite discoveries.

Kimberlite samples totalling 12.2 tonnes combined were tested to determine the variability of the geochemistry, to develop preliminary comparisons to other kimberlite fields, and to determine the most promising locations suitable for excavating large tonnage bulk samples. RJK is pleased to report that CF Mineral Research confirms the Lorrain Twp. kimberlite discoveries host lherzolite-type kimberlite where large diamonds (50 carats+) are typically found. The unique geological setting presents the availability of unconsolidated near-surface kimberlite material that is amenable to exceptional low cost processing wherein minimum 50 tonne bulk samples, from multiple locations, can be used to determine the large diamond potential.

Synopsis

The indicator mineral geochemistry from all 7 kimberlite bodies indicates the kimberlite magma has incorporated lherzolitic peridotite enriched in olivine, orthopyroxene along with chromium and aluminum spinels and garnets. This region at the base of the lithosphere and upper mantle is conducive for the growth of large diamonds in the diamond stability field at depths of 150 km to 200 km. The high temperature ilmenite peridotites contain megacrysts favouring larger diamond overgrowths forming at temperatures ranging from 1200 Co to 1400 Co. The proto-kimberlite magma indicates an origin of deeper levels in the upper mantle as down to the Transition Zone, from 200 km to 400+ km, based on preliminary whole rock analysis. Samples taken from 4 RC drill holes from the Paradis, Robin's Place, Gleeson and HSM kimberlites returned average compositions as follows: SiO2: 46.8%, CaO: 16.9%, Al2O3: 8.8%, Fe2O3: 3.2%, K2O: 1.9%, MgO: 4.3%. Na2O: 1.9%, Cr2O3: .04%, Mn2O3: .06%, TiO2: .29%.

Comparisons

Dr. Charles E. Fipke previously stated RJK's Paradis Kimberlite hosts diamond inclusion lherzolite indicators such as those contained at the Victor diamond mine in Ontario and other diamond mines in Lesotho and elsewhere. This statement was also true for surrounding kimberlites, with emphasis on the Nicol Kimberlite body. The picro-ilmenite plots show similarities to the Yakutia Kimberlite Fields in Siberia showing peridotite magma affinity. Cr-poor ilmenites (0.04 to 0.23 wt%Cr2O3; 9.7 to 11.3 wt% MgO) occur as intergrowths with type II diamonds, and the Lorrain Kimberlite Field ilmenite plots display these same ranges. Comparisons were also made to De Beers Victor Lherzolite Diamond Mine, which was unique in its chemistry, yielding exceptional quality diamonds, but also hosting very few microdiamonds. Victor lherzolitic garnet inclusions have unusually high MnO contents, with 88% exceeding the MnO cut-off >.36 weight% MnO for diamond facies garnets. (Refer to following histograms). The Lorrain Twp. kimberlite results suggest a certain level of diamond resorption (especially for any smaller stones), the kimberlite magma also has experienced a reducing environment conducive for diamond preservation based on picro-ilmenite geochemistry. The picro-ilmenite plots from the Lorrain Twp. kimberlites compare favourably with the Yakutia kimberlite field plots depicted in the Geotechnical Discussion.
