Margaret Lake Diamonds announces the commencement of ground

geophysical exploration on the Diagras property NT

May 8, 2017- Vancouver, British Columbia—Margaret Lake Diamonds (“DIA” or the “Company”)

(TSX-V: DIA) is pleased to announce that its joint venture with Arctic Star Exploration Corp

(“ADD”) (TSX-V: ADD) has initiated a ground exploration program on its Diagras property. DIA is

the operator of this program with a 60% interest and ADD contributing 40 %. Diagras is located in

the north-eastern part of the prolific Lac de Gras kimberlite field, 22km NNE of the Diavik diamond

mine and 36km east of the Ekati diamond mine in NT Canada. Research and data compilation

shows that the property hosts over a dozen kimberlites, with most of them diamondiferous.

The claims selected by the company comprise 23 and total 18,699hectares, forming the Diagras

property. The property was obtained by posting a bond of approximately $200,000 with the

Government of the Northwest Territories.

The Diagras property is located in the prolific nor th-northeastern part of the Lac de Gras

kimberlite field where the Diavik (operated by Rio Tinto PLC) and Ekati diamond mines (operated

by Dominion Diamonds Corp.) are located. The follow ing diamondiferous deposits A21, A418,

A154S, A154N, Piranha Lynx, Misery, A841, and Jay k imberlite pipes, line up in a >25 km.

structural corridor trending NNE into the Diagras property. The nearest of these pipes, Jay is just

8.9 kilometers from the Diagras boundary.

Diagras has diamondiferous kimberlites

Historical work on the Diagras property was origina lly conducted by De Beers in the 1990s and

some subsequent work by Majescor Resources in 2004. Whilst being explored by De Beers it was

known as the Hardy Lake property, it was their work that identified the 13 known kimberlites on

the Diagras property controlled by the joint venture.

Originally the kimberlites were discovered primaril y as the result of follow-up of airborne

magnetic surveys some 2 decades ago. In some instan ces short holes were drilled that did not

explain the magnetic anomalies.

Exploration Strategy

The Joint Venture has mobilised crews to undertake ground geophysical surveys in the area of

known kimberlites and also to evaluate other previo usly unresolved targets. The geophysical

surveys will comprise of ground gravity, magnetics and the OhmMapper ground EM method. The

objective of this work is to attempt to detect previously undiscovered non-magnetic phases near

the original magnetic kimberlite discoveries. The Jack Pine kimberlite, one of the 13 kimberlites

in our portfolio, is one such large complex kimberl ite, with multiple phases with different

geophysical responses. It is hoped that our planned surveys will reveal similar geology around the

other pipes. There is also a good chance to find n ew kimberlites using these new ground

geophysical techniques. This ground geophysical wor k has now commenced and is designed to

establish drill targets which will be slated for testing in the next phase of the exploration program.

Field work on this program calls for completion in mid-May which will then require interpretation.

Current weather and ground conditions are considered good for this program.
