(TSXV: RJX.A) (OTC: RJKAF) (\"RJK\" or \"the Company\") is pleased to announce that 7 natural microdiamonds, varying in colour from clear to white have been recovered from the 277 kg (611 lb) drill core sample from the KON 1 target drilled earlier this year. Three of the diamonds were chips with a greenish tinge and the other four are white diamond chips and macles. The chips are generally flat with one being triangular shaped, possibly a broken fragment from a larger stone. There are no inclusions in the diamonds recovered. Due to the diamond and indicator mineral results, RJK has plans for follow-up drilling on KON 1, using a drill capable of large diameter coring. The objectives will be to establish the 3D pipe geometry, the geology of the structure and correlate the kimberlite phases to optimize the microdiamond sampling by discrete phases. RJK plans to post a video with principal geologist, Peter Hubacheck, explaining the company's in-depth analysis of the KON exploration program.Kimberlite Indicator Mineral (KIM) ResultsKIMs were separated and tested, returning materially important results. A total of 44 KIM grain determinations were identified, that commonly derive from kimberlite sources originating in the \"diamond stability field.\" The diamond stability field is located from depths of about 200 km in the earth at the lower boundary of the continental lithosphere with the convecting mantle. From the heavy mineral concentrates, 1,200 grains were picked and classified into five diamond indicator mineral classes: picroilmenites and chromites, peridotitic pyroxene, diatreme clinopyroxene, diatreme olivenes and peridotitic garnet. Of the 119 grains analysed by electromicroprobe, 20 were high titanium chromites, 17 were clinopyroxene including 7 derived from eclogitic magma, 4 were G10 garnets, 2 were forsterite-olivene, 1 was a G11 garnet and all formed in the diamond stability field along with the diamonds. The samples were processed by CF Mineral Research Ltd. (CFM), an ISO 9001:2015 certified and 17025:2005 compliant laboratory, owned by Dr. Charles E. Fipke.Of interest was the chr...
