[{"type":"text","content":"RJK Explorations Discovers 18 Diamonds from a 22.4 kg (50 lb) Core SampleKirkland Lake, Ontario--(Newsfile Corp. - April 1, 2020) - RJK Explorations Ltd. (TSXV: RJX.A) (OTC: RJKAF) (\"RJK\" or \"the Company\") is pleased to announce that at least 18 natural diamonds, varying in colour, have been recovered in a 22.4 kg (50 lb) drill core sample. Four of the stones that appear natural are -0.212+0.150 mm in size. One is light yellow, one is light green and two are white in colour. These are mostly partially crystalline chips and are clear with single tiny inclusions in two of the stones. Seven of the stones thought to be natural are -0.150+0.106 mm in size. Five of these are clear white broken fragments, one is clear white with broken dodecahedral crystal faces and one is a light brown diamond fragment. Fifty-two diamonds were recovered that are -0.106 mm in size. Seven are tiny clear white chips thought to be natural. The remaining forty-five stones are described as tiny, clear yellow chips, but the tiny size limits determining whether or not these are synthetic stones from the drill bits used to recover the tested core, or alternately chips from natural stone(s). The mini-bulk sample was processed by CF Mineral Research Ltd. (CFM), an ISO 9001:2015 certified and 17025:2005 compliant laboratory, owned by Dr. Charles E. Fipke. This test result marks RJK's first confirmation of diamonds in our search for the source of the 800-carat, yellow Nipissing Diamond.Kimberlite indicator minerals (KIMs) were also separated and tested, returning materially important results. A total of 28 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, 164 grains were probed and classified into six diamond indicator minerals: chromite, high manganese ilmenite, peridotitic pyroxene, clinopyroxene, eclogitic garnet and peridotitic garnet. Of the 164 grains analysed by electromicroprobe, twenty-three were G10 peridotitic garnets, three were diamond inclusion G11 garnets, one was a G1 eclogitic garnet and one was a diamond inclusion chromite, all formed in the diamond stability fiel...
