Margaret Lake Diamonds Announces Commencement of Exploration at Diagras Property,

Northwest Territories, Canada

VANCOUVER, BC / ACCESSWIRE / May 30, 2018 / Margaret Lake Diamonds Inc. (TSX-V: DIA;

FSE: M85) (''Margaret Lake'' or the ''Company'') is pleased to report that exploration has commenced on

its Diagras Property (''Diagras'' or the ''Property'') located in the Northwest Territories, Canada.

The exploration program will consist of Gravity, Magnetic and Electromagnetic (EM) ground surveys

focused around historically identified kimberlites as well as other airborne geophysical anomalies with

kimberlite like signatures. This ground work will provide detailed data for further analysis and

interpretation to identify additional kimberlite potential and targets.

Diagras is a contributing Joint Venture (the ''Joint Venture'') between Margaret Lake, which acts as

project operator and holds a 60% interest, and Arctic Star Exploration Corp. (ADD) which holds a 40%

interest. Diagras is located in the prolific Lac de Gras diamond field, Northwest Territories, Canada and

just 35 km from the world-class Diavik diamond mine. The Property lies directly on trend with the Diavik

deposits currently being mined by a joint venture between Rio Tinto and Dominion Diamond Diavik. The

Diagras land package consists of 18,699 contiguous hectares of mineral claims containing 12 previously

identified kimberlites.

Diagras Land Package within Lac de Gras Diamond Field

Detailed, modern ground geophysical techniques are being employed to define possible additional

kimberlite(s) or kimberlite phases missed by previous explorer De Beers Canada, who did not utilize all

these techniques. This exploration approach has been successful elsewhere and recent examples include

the discoveries of additional diamondiferous kimberlite at the Kelvin and Faraday kimberlite complex

(Kennady North project). A second example that further validates the exploration premise is the Tli-Kwi-

Cho DO 27, DO18 kimberlite complex also located in the Lac de Gras diamond field. It comprises

multiple eruptive/intrusive events of kimberlite, each of a different style and with different geophysical

expressions (Mag only, Mag and EM, Gravity, EM and Gravity).

2017 Exploration Program

The Joint Venture was also successful using this strategy during the spring 2017 exploration program.

This work revealed gravity and EM anomalies proximal to known magnetic kimberlites that constitute

compelling drill targets. At the Jack Pine kimberlite, which is one of the largest kimberlite complexes in

the Lac de Gras diamond field (over 1.5km in its longest dimension), the geophysical methods (ground

gravity, EM and magnetics) highlighted obvious magnetic kimberlite phases drilled by previous explorer

De Beers Canada while also successfully defining a new kimberlite-like geophysical expression. This area

remains to be drill tested. Previous drilling elsewhere in the Jack Pine kimberlite complex has

demonstrated it is diamond bearing.

Targets of great interest were also generated in 2017 at the Black Spruce kimberlite. A series of gravity

lows occur adjacent to the south of the known magnetic phase of the kimberlite. One of these gravity

anomalies clearly breaks and disturbs a diabase dyke, a characteristic similar to known Lac de Gras

kimberlites.
