Clarification From Stornoway Diamond Corp.

The Renard Mine continues in operation

LONGUEUIL, April 12, 2019 - Stornoway Diamond Corp. (TSX-SWY; the “Corporation” or “Stornoway”) is providing clarification regarding recent media articles, stating that its Renard Mine continues to operate. The Corporation did not announce the closure of its Renard Mine, but only the temporary suspension of open pit mining operations at its Renard 65 ore body, one of the 3 ore bodies currently in operation at the Renard Mine, and the only ore body currently mined by open pit. The Renard underground mine, which extracts kimberlite from the Renard 2 and Renard 3 kimberlite pipes, provides approximately 93% of the mine's total production. Along with the current Renard 65 ore stockpile, this is sufficient to maintain 100% of the planned feed to the process plant. Therefore, this decision does not reduce the carat production of the Renard mine, but allows for the better management of capital resources, by reducing operating costs and deferring certain capital expenditures.

Reacting to news reports and comments in the media today, Patrick Godin, President and CEO of Stornoway, wanted to re-establish the facts while ensuring that Stornoway continued to evaluate the options available to improve its balance sheet and remains confident in the support of its partners.

Mr. Godin wished to remind that the global diamond market is going through a difficult time and that Stornoway’s mine sells its product at a lower price than in previous years and much lower than initially anticipated during the construction of the mine. The challenges faced by the Corporation are mainly due to the significant drop in the price of diamonds in world markets.

With respect to diamond breakage, Mr. Godin reiterates that the level of diamond breakage is now within industry standards following improvements to the recovery process.

“In addition, the company would like to underline the fact that the mine's operations are stable and we are fortunate to have competent and committed employees, contractors and suppliers," he continued.

Notable achievements

Mr. Godin reminded all the following achievements that have made the Renard Mine an example in terms of social acceptability and sustainable development:

• A socially and economically engaged partner with the Cree and James Bay communities, as well as with many Quebec suppliers;
• A leader recognized for its management and environmental performance;
• A team of more than 700 committed people that are proud to produce diamonds in Quebec.

QUALIFIED PERSON

Disclosure of a scientific or technical nature in this press release was prepared under the supervision of Mr. Patrick Sévigny, P.Eng. (Québec), Vice President, Operations, a “qualified person” under National Instrument (“NI”) 43-101.
