MATAMEC INTERSECTS 1.7 G/T AU OVER 30 M, INCLUDING 4.26G/T OVER 4.5M, EXTENDING THE STRIKE LENGTH OF ZONE 25 TO 700 M ON THE SAKAMI PROPERTY

Matamec Explorations Inc. and Canada Strategic Metals Inc. have released complete results from the 2017 spring drilling campaign on the Sakami property, of which the two companies each own 50 per cent. A total of 2,925 metres of drilling were completed in seven drill holes (PT-17-100 to PT-17-106) along the shore of Sakami Lake to extend the known mineralized body to the west and at depth. This drilling successfully extended the strike length of the zone to 700 m and appears to support the theory of higher-grade subdomains with rakes trending west-southwest. The broken core in drill hole PT-17-104A and the disjointed nature of PT-17-105 highlight the increasing geological complexity to the west. PT-17-105 was halted in mineralization, having reached drill rig depth capacity at a vertical depth of 450 m. Further investigation will be required to understand its relation with zone 25 and define its full width.

The highlights of this lot of results are from PT-17-102 with 1.7 grams per tonne over 30 m including 4.26 g/t over 4.5 m and PT-17-106 with 1.17 g/t over 10.5 m. Drill hole PT-17-104 was recollared (PT-17-104A) and did not reach the target depth due to poor rock quality, possibly related to a fault zone. However, it did intersect 3.82 g/t over three m at a shallower level and in a similar geological context as zone 25. Drill holes PT-17-103 and PT-17-105 did not intersect any significant Au mineralization at the expected intervals in the drilling, which highlights the potential geological complexity at the western extent. Further interpretation and geochemistry on the nature of a new diorite intrusion in the sequence should give a better understanding of the geological model as it will confirm the rock composition as a diorite or a highly altered paragneiss. This potential diorite could add to a growing list of similarities with the Goldcorp's Eleonore deposit. Mineralized intervals for PT-17-100 and PT-17-101 have previously been announced. The best intersections for the entire 2017 drill campaign are displayed in the associated table.

CSM recently exercised an option to acquire another 20 per cent of the Sakami property from Matamec in exchange for one million shares in the company and a commitment to spend $2-million per year on exploration over five years and complete an independent bankable feasibility study. Please see the press release from Feb. 14, 2017, for more details of the option agreement and the ownership structure of the property. During the period covered by the option agreement, CSM will remain the operator of the exploration work, supervised by a management committee comprising two representatives of CSM and two representatives of Matamec.

Dr. Guy Desharnais, PGeo, PhD (OGQ No. 1141), is a qualified person as per National Instrumen 43-101; he is employed by SGS Canada Inc., is independent of Matamec, and has reviewed and approved the technical content of this press release.

"These results appear to support our belief that there is significant gold potential at Sakami," said Andre Gauthier, president and chief executive officer of Matamec. "The extension of zone 25 to the west is encouraging, and we look forward to further investigation of this area of mineralization."

About Matamec Explorations Inc.

Located in Montreal, Que., Matamec Explorations is a junior mining exploration company in which activities are based on two main axes of development: gold and key elements for technologies related to energy with properties containing, among others, lithium (Tansim -- owned at 100 per cent), cobalt (Fabre -- 100 per cent owned), nickel (Vulcain -- 100 per cent owned) and rare earths (Kipawa -- 72 per cent owned by Matamec).

Matamec's main focus is the development of the Kipawa heavy rare earth elements (HREE) deposit, a joint venture owned at 72 per cent by Matamec and 28 per cent by Ressources Quebec (acting as agent of the government of Quebec); Toyota Tsusho Corp. (Nagoya, Japan) holds a 10-per-cent royalty on net profit in the deposit.

In addition to the activities in energy sector, Matamec is exploring for gold, with two properties (Matheson JV (50 per cent) and Pelangio (100 per cent)) located in the area of the Hoyle Pond mine in Timmins, Ont., as well as three in the Quebec Plan Nord region in similar geological settings as established gold-producing mines.
