Arctic Star Confirms Diamonds in a New Kimberlite Field, Finland

"Arctic Star views this new Project as a unique opportunity to advance a new diamond district", says Buddy Doyle, VP Exploration of Arctic Star. "The 100%-owned Project offers diamond bearing kimberlites that allow for immediate further work to assess their economic potential. The Project is road accessible, and located on excellent infrastructure in mining friendly Finland."

Vancouver, British Columbia--(Newsfile Corp. - July 12, 2017) - Arctic Star Exploration Corp. (TSXV: ADD) (FSE: 82A1) (WKN: A2DFY5) ("Arctic Star" or the "Company") is pleased to announce that it has agreed to acquire a 100% interest in a 243Ha Exploration Permit over the Black Wolf (Masta Susi) and the White Wolf (Valkoinen Susi) diamond bearing kimberlites (together the "Wolf kimberlites") in northern Finland. The Exploration Permit is being acquired via a Share Exchange Agreement with the Finnish holding company (transaction details below).

Furthermore, the Company has filed application for an Exploration Reservation centered on the acquired Exploration Permit.The Reservation is approximately 95,700 hectares in size, and it provides Arctic Star with exclusive rights to acquire additional exploration permits for a 2 year period.

The combined regional exploration and diamondiferous kimberlite property has been named the Timantti Project (Timantti is Finnish for "diamond").

Mr. Roy Spencer, who discovered the Wolf kimberlites also led the team that discovered the Grib Diamond Mine near Archangelsk, Russian Federation, has joined Arctic Star's Board. "Kimberlites are likely to occur in fields - also known as clusters - which typically contain 30 or more separate kimberlites. The Wolf kimberlites are just the first discoveries in a more extensive cluster," according to Roy Spencer. Roy continues: "There is good evidence for the existence of this field in the public domain. This data shows regional distribution of kimberlitic indicator minerals and diamonds in surficial tills. The Exploration Reservation will allow Arctic Star to explore the entire region".

A 43-101 technical report titled, "Geological Report on the Foriet Diamond Property, Finland" authored by Kevin R. Kivi, P.Geo, of KIVI Geoscience Inc. has been filed by the Company on SEDAR.The author confirmed the diamond-bearing nature of the Wolf kimberlites by submitting samples collected from kimberlite float in overburden during a due diligence site visit. Microdiamond results are shown in Table 1.

Microlithics Laboratories Inc., of Thunder Bay, ON ("Microlithics") is independent of the issuer, and is not ISO accredited. Kevin Kivi, P.Geo. has audited Microlithics to verify sample preparation and analytical methods for diamond recovery were appropriate.

Mr. Doyle continues "the opportunity for an economic discovery at Timantti is substantially improved by easier access than companies face in in northern Canada and Siberia. The Wolf kimberlites represent the first discoveries in a possibly more extensive diamondiferous kimberlite field."

"Both Roy and Buddy have led Tier 1, major company diamond mine discovery teams, and previously collaborated on diamond projects in Finland and on the development of the Lihqobong Diamond Mine in Lesotho," commented Mr. Patrick Power, President and CEO of Arctic Star. "Roy's extensive local knowledge and experience will mean we can hit the ground running in Finland, and we expect to commence work immediately upon closing of the transaction."

The Wolf kimberlites were discovered by European Diamonds PLC in 2005. The discovery team was led by Mr. Spencer. European Diamonds made the discoveries by drilling a low-magnitude magnetic high anomaly at the head of a prominent G10 pyrope garnet-bearing kimberlitic indicator mineral ("KIM") train they had traced over 30km. In total eight (8) angled diamond drill holes were completed on the bodies. Some 41.2kg of kimberlite, which comprised pyroclastic and hypabyssal phases, were collected. In September 2005 European reported "micro -diamond analysis at the laboratories of Kennecott Canada Exploration in Thunder Bay, Canada, identified a total of 42 small diamonds between 0.15 and 0.88 mm in size from 4 samples totaling 41.2kg in weight. Sample processing was performed to the ISO/IEC17025 standard. Eleven of the 42 diamonds have a longest axis equal to or greater than 0.5mm with the largest stone having a long axis of 0.88mm. Approximately 26% of the stones were white and some 38% were octahedrons".

In 2006 European Diamonds changed its name to Kopane Diamond PLC. An 8.8t kimberlite sample was extracted from the Wolf kimberlites from two shallow backhoe trenches. These samples were run through a gravity separation circuit at the Finnish government facility in Outokumpu. 1.25 carats of stones greater than 1mm were recovered. The largest stone recovered was 0.09 carats.

Buddy Doyle further comments, "The high microdiamond count, 77 stones (greater than 0.15mm), from the two small samples totaling 60.1kgs (European plus Arctic Star Caustic Fusion samples) is a significant result.Backhoe trenching results are significant because they show the Wolf pipes contain diamonds of over 1mm.

The Wolf kimberlites occur on the Fennoscandian Shield which hosts the world class (multi-billion dollar revenue) diamond mines at the Arkhangelskaya kimberlite (Lomonosov Mine) and Grib kimberlite (Grib Mine), both near Arkhangelsk Russia (450km East of Wolf). In Finland the diamond bearing Kuopio kimberlite field occurs on the exposed Archaean Karelian Craton segment of the Fennoscandian Shield, south of the Timantti Project.

Arctic Star believes that the diamond bearing Wolf kimberlites signify the first discoveries in a new diamond bearing kimberlite field. This view is supported by public data showing "cloud" of KIMs distributed across an area that is some 80km wide and roughly centered on the Wolf kimberlites.

Patrick Power, President and CEO comments, "I believe that a commanding land position around the Wolf kimberlites is the key to ensuring our shareholders have maximum exposure to discovery in this new and exciting diamond district, which we believe offers high potential for numerous further diamond-bearing kimberlite discoveries. This to me is the most exciting aspect of the Timantti project."

After closing the acquisition, the next steps are to quickly gain a better understanding of the Wolf kimberlites. The Arctic Star field visit confirmed the Wolf kimberlites contain both pyroclastic (formed near surface) and hypabyssal (formed at depth) kimberlite types. Arctic Star plans to complete detailed magnetic, gravity and EM (electro-magnetic) geophysical ground surveys, which will be used to target further drilling. Drilling will help define the shape and tonnage of each kimberlite and collect more material for caustic fusion analysis for microdiamonds. The microdiamond distribution will determine the parameters of a bulk sample (to determine diamond grade and value).

To swiftly discover more kimberlites on the Timantti Project, Arctic plans to fly airborne geophysical surveys to cover the entire region that hosts KIMs. The Company will improve targeting by detailed ground follow up of the indicator mineral anomalies in the area.

Arctic Star has entered into a Share Exchange Agreement dated effective June 7, 2017 and agreed to issue 14,500,000 common shares at a deemed price of $0.20 per share for all the right, title and interest to Foriet Oy, a Finnish company that has the 243Ha exploration permit over the Wolf kimberlites in North-Eastern Finland. 10,000,000 of the Arctic Star shares are to be issued to Dragon Equities Ltd., a UK company, which indirectly owns Foriet Oy, and 4,500,000 shares will be issued to the beneficial owners of a joint venture partner of Foriet Oy. On completion of the Share Exchange, Foriet Oy will become a wholly owned subsidiary of Arctic Star.

In addition to the 4 month hold period imposed by securities regulation, all shares issued in the transaction will be subject to a Value Securities Escrow Agreement whereby the shares are released over a 3 year period. Closing of the Share Exchange Agreement is subject to TSX-V approval.

The Company welcomes Mr. Roy Spencer and Mr. Scott Eldridge to the Board of Directors.
