Arctic Star Announces Diamond Count of 758 Stones from Drilling at Timantti Diamond Project, Finland

Vancouver, British Columbia--(Newsfile Corp. - July 5, 2018) - Arctic Star Exploration Corp (TSXV: ADD) (FSE: 82A1) (OTCQB: ASDZF) ("Arctic Star" or the "Company") is pleased to announce the second set of results from drilling at the White Wolf kimberlite occurrence at its 100% owned Timantti Diamond Project near Kuusamo, Finland (the "Project"). The results are from caustic fusion method on a composite 262.33kg of split HQ drill core from Spring 2018 drilling at the Project.

Complete results from the White Wolf kimberlite are reported below and include the past caustic fusion diamond results ("Previous") and the results just received ("New"), for a combined total of 1,032 diamonds from 409.3kg of White Wolf kimberlite.

Table 1: Micro Diamond Assay Results, White Wolf Kimberlite

Notes: Previous results where a mixture of core and surface samples processed at Micolithics and Saskatchewan Research Council ("SRC") Saskatoon, Saskatchewan. Both laboratories are independent of the issuer, SRC is an ISO9000 laboratory, A Chain of custody protocol was adhered too. Sample weights are dry weights.

Arctic Star completed initial exploration and delineation drilling at the Project in Spring 2018. Exploration located four separate kimberlite occurrences including the White Wolf, Black Wolf, Grey Wolf and Vasa Dyke Swarm.

Results from the White Wolf kimberlite will now form the basis of the interpretation process. This work is based on the size distribution of the diamond results for the purpose of providing an estimate of overall grade as well as guidance for size of bulk sample, should a decision to proceed with bulk sampling be made. A bulk sample containing >1000 carats of commercial sized diamonds would be needed to obtain a view of the average price of the diamonds in the kimberlite. At which stage the first economic estimate could be made.

Buddy Doyle, VP of Exploration stated, "We are very encouraged by the diamond results from White Wolf kimberlite, we await the diamond results from Black Wolf, and Grey Wolf, expected prior to the end of this month. With all the results in hand we can plan the next stage for these kimberlites. However, our focus will be more on finding more, we expect we are in a larger kimberlite field based on diamond indicators in the till in the area with at least several separate sources. It would make more sense to explore, find and do similar caustic fusion analysis to make an inventory of kimberlites that need bulk sampling, prior to doing this exercise on the Wolves."

A summer exploration program is underway to identify additional kimberlites including esker and till sampling, in addition to focused airborne and ground geophysical surveys.
