STAR - ORION SOUTH DIAMOND PROJECT

APPROVED BY PROVINCIAL MINISTER OF ENVIRONMENT

Star Diamond Corporation (“Star Diamond” or the “Corporation”), is pleased to announce that the

Saskatchewan Ministry of Environment (“Ministry”) has approved the Corporation’s Star - Orion South

Diamond Project (“the Project”), located in the Fort à la Corne diamond district of central Saskatchewan,

Canada, on mineral dispositions held 100 percent by Star Diamond.

The Environment Minister of Saskatchewan Dustin Duncan announced approval for the Project under

The Environmental Assessment Act, indicating the “The Star -Orion South Diamond Mine is a major

development with the potential to bring jobs to the area and diversify Saskatchewan’s economy” . A

copy of the Project decision can be found at publications.gov.sk.ca/deplist.cfm?d=66&c=4428. The

Canadian Environment Assessment Agency previ ously announced a positive federal Environmental

Assessment Decision for the Project (see News Release dated December 3, 2014).

Kenneth E. MacNeill, President and CEO states: “This approval, alongside the previous positive Federal

decision, marks a major milestone towards the development of a diamond mine in Saskatchewan. We

have previously demonstrated that the proposed Star - Orion South Diamond Project can be successfully

constructed and operated and are very pleased that the Pro ject has now received positive federal and

provincial environmental decisions. This milestone is the result of the significant work and effort of the

Ministry, our technical team and consultants, and represents our commitment to our stakeholders and

the community surrounding the Project. As illustrated by the p reliminary economic assessment, the

Project has the potential to generate billions of dollars of corporate and municipal taxes and royalties,

while also providing direct employment for hundreds of people throughout the construction phase and

some 700 people continuously over its 38 year mine life.”

The Ministry has indicated that they conducted a thorough environmental assessment for the Project,

including a detailed environmental impact statement, and carried out in -depth consultation prior to the

decision to approve the P roject. This included fulfilling the Province’s duty to consult responsibility. The

Government of Saskatchewan consulted with local First Nations and Métis communities and has

developed accommodations that will address potential adverse impacts to Treaty rights and traditional

uses. Prior to proceeding with the Project, further provincial and municipal permits and approvals will be

required.
