Chemical fusion process results obtained from the other half of the Sequioia Kimberlite 2021 drill core still suggest the presence of large diamonds. The results come from the remaining drill core from drill holes 202 meters apart, located in the Central and Northern Sequioia Kimberlite Complex.
Thus, the entire core, totalling 505 kg. has been fused or chemically processed. Normally, half of the core is kept for reference but in this case, the decision to treat the whole core stemmed from the heartening or auspicious results of the first half and the encouraging indicator minerals reported in the Arctic Star company’s September 7,2021 newswire report.
The sample results showed that they contain two different rock types, the volcanoclastic kimberlite and the coherent kimberlite. While both types have indicators for large diamonds found globally, including diamond chromite, the coherent kimberlite shows significant results.
According to Buddy Doyle, an award winning geologist with 35 years of experience in diamond exploration, discovery and evaluation, the results suggest that the current sample size , if increased to 10 times or to about 5 tons, would produce a smooth diamond size frequency curve from which a global grade estimate could be obtained. Such a sample size should also provide guidance to the probability of large stones. Drilling at the Sequoia Kimberlite complex is planned for Spring 2022 to achieve these goals.
