Dunnedin Ventures Inc. today announced new diamond results from the kimberlite pipe KD900 and the completion of summer/fall field work at its 100% owned Kahuna Diamond Project in Nunavut, Canada. As noted in its July 19, 2018 news release, the Company has drill-tested two historic kimberlite pipes (KD900 and KD230) and in addition, discovered a new pipe (KH10-11). All three kimberlites were tested using rotary air-blast (“RAB”) drilling during the summer and approximately one tonne of representative material was sent to CF Mineral Research Ltd. (“CFM”) in Kelowna, British Columbia for analysis. Further diamond results on KH10-11 and KD230 will be reported as received, with the next tranche of results expected later this fall. Any significantly diamondiferous kimberlite will require further drill-testing and possibly mini-bulk sampling to determine kimberlite geometry, diamond grade and size frequency distribution.
Highlights include:
•Initial results from 133.32 kilograms of KD900 include 18 diamonds larger than the 0.106 mm sieve size. Diamond recovery results are presented in Table 1.
•Indicator minerals from KD900 confirm that while this pipe is diamondiferous, it is not the sole source of high-quality diamond indicator mineral (“DIM”) chemistry present in the Josephine Target Area (“JTA”).
•DIM chemistry and indicator dispersion in the JTA suggest undiscovered kimberlites with the potential to host larger diamonds occur near KD900 and up-ice.
