Summary: EMP Data – Paradis Pond Core
- EMP – Electron microprobe, analyses the various grains of interest in a kimberlite for specific levels of certain elements that match those found in kimberlites and/or found as inclusions in diamonds.
- DSF – geochemical analysis can identify if the KIMs/DIMs were formed in the diamond stability field along with the diamonds.
- In total, 28 grains have properties possibly sourcing from the diamond stability field.
- The Paradis Pond kimberlite and other Bishop targets are located in the Temiskaming Rift Valley system, which continues to the Victor Diamond Mine in Attawapiskat, as well, both are emplaced into the central Archean Superior Craton.
- If the 22.4 kg sample was an accurate representation of the source, the Ilmenite chemistry and other indicator mineral results from Paradis Pond signify the source should have low resorption, meaning diamonds were not burned in transport.
- The detailed analysis of the 18 diamonds discovered by CFM Research in the Paradis Pond drill core contains proprietary and confidential information, and therefore has not been included in this report, but RJK has included one table of Charles E Fipke’s comments on some of the diamonds discovered.
Highlights of the results from 22.4 kg (~50 lbs) of core from Paradis Pond follow:
- Cr – 10 chromites
- Cr Ti – 1 chromite with high titanium – such grains are only derived from kimberlite or lamproite sources
- Cr Si – 1 chromite with high silicon
- Cr04 DI – 1 chromite with diamond inclusion composition, score 4 of 10 (DSF)
- Il-Mn – 4 ilmenites with high manganese, produced during kimberlite emplacement
- Il-Mn D10 – 8 ilmenites of diamond inclusion composition that overlaps with high manganese composition from non-diamond bearing sources
- OP5 – 1 orthopyroxene, Group 5
- OPx – 1 orthopyroxene
- PIl – 10 picroilmenite, (magnesium) Mg-ilmenite, helps determine whether diamonds in the kimberlite were resorbed (burned up) in the kimberlite ascent. The PIl microprobe results (and surface features and texture of the grains) indicate very little resorption in the Paradis kimberlite; therefore, increases the chance of larger diamonds
