“Searching for the Source of the 800 Carat Nipissing Diamond”

RJK Explorations Ltd. Exploration Update including the Findings from an Initial Review by

the SRK Consulting Group

Kirkland Lake, Ontario – July 27, 2022 – RJK Explorations Ltd. (TSX-V: RJX.A, US OTC. RJKAF) (“RJK” or “The

Company”) has and continues to engage with subject matter experts throughout its ongoing diamond

exploration program to investigate and theorize on the continuous compilation of data derived through its

various exploration activities to date. In addition, RJK plans on further evaluating the Kon prospect where

there are numerous untested targets, as well as the under -explored Peddie Kimberlite. This work would be

concurrent to regional glacial examination and the continued evaluation of the diamond bearing g lacial

material.

RJK has received a report completed by Casey Hetman, M.Sc., P.Geo. and Kimberley Webb, M.Sc. P.Geo. of

the SRK Consulting Diamond Group (SRK) titled an “Initial Sample Review” of four samples representing four

separate areas that were drilled for diamond potential. As noted in the news release dated March 21, 2022,

SRK was engaged to complete a review of data and samples that have currently been collected on RJK’s

Nipissing Diamond Project and provide recommendations on the Company’s future exploration efforts.

The four small samples examined are as follows: two drill core sections each from Paradis Pond and HSM

prospects, one excavated sample from the Nicol prospect and one drill core section from the Kon prospect.

Thin sections of the samples were examined and a subset of the Paradis, HSM and Nicol samples were washed

and cleaned of mud for examination under binocular microscope, as well as the crystals and lithic clasts that

were collected in a sieve and pan. Mr. Casey Hetman visited the RJK claims in the Cobalt-Temiskaming Shores

area on April 22-23, 2022, as well as the RJK core storage facility where the drill core is currently stored.

SRK has concluded from this initial review that the Paradis, HSM and Nicol prospects represent gla cial

material containing kimberlite indicator minerals. At the Kon Prospect, SRK has concluded that the rock

uncovered in that locality is kimberlite.

RJK previously hypothesized the deposits at Paradis, HSM and Nicol could have originated from eruptions

underneath the last glacial event; given their location along major fault systems, the presence of micro

diamonds and kimberlite indicator minerals as reported by RJK in 2021, and stratigraphic position deposited

above bedrock but below a younger glacial t ill sheet. SRK recognizes the significance of the fact that the

indicator mineral chemistry reported by RJK for the glacial deposits is different from that of past work by

previous diamond explorers in what continues to be an interesting and attractive exp loration prospect for

the Company. SRK has recommended to widen the search to explore locations ‘up -ice’ from RJK’s

diamondiferous glacial material to determine where it originated. As a follow up, RJK will be consulting with

expert glaciologists as part of SRK’s recommendation to further investigate the available data to evaluate and

prioritize ‘next step’ targets up-ice. SRK believes it would be beneficial to conduct a regional compilation of

existing kimberlites and other potential, primary diamond sourc e rocks and their associated chemistry to

narrow down target selection for ultimate follow -up drilling. RJK has begun this process by assembling an

expert team with extensive diamond exploration and discovery experience in the Temiskaming region. The

expert team started by reviewing the data on the 38 known kimberlites discovered in the Temiskaming region

on the list compiled by retired Ministry kimberlite specialist Gary Grabowski, advisor to RJK.

Gino Chitaroni, President, RJK Explorations Ltd. “Our goal has been to find the source of the Nipissing

Diamond and in doing so, discover a diamond mine in the Cobalt area. Considering the quantities and type

of kimberlite indicator minerals found in these diamondiferous glacial deposits, we believe the source

eruption is likely undiscovered and proximal to their locations. Given the chemistry, and what we have

learned from consultants to date, the RJK team feels very confident that there is an economic deposit for the

diamonds in the Cobalt Mining Camp. This most recent study conducted by SRK brings us one step closer to

achieving that goal and during the past 9 months RJK has been identifying targets to drill, starting in August

2022.”

RJK is in the process of updating the website to include this new informati on from SRK, and further details

on the Company’s plan will be disclosed in follow-up press releases.

Mr. Peter Hubacheck, P. Geo., Project Manager for RJK and the Qualified Person as defined by National

Instrument 43-101 has approved the technical disclosure in this release.
