Morien Provides Update on Environmental Assessment Process for Donkin Coal Project

Canadian Environmental Assessment Agency Releases Comprehensive Study Report and Initiates 30-Day Public Review Period

Morien Resources Corp. (“Morien” or the “Company”) (TSXV:MOX) is pleased to report that on April 9, 2013 the Canadian Environmental Assessment Agency (“CEAA”) released a Comprehensive Study Report (“CSR”) for the Donkin Coal Project (“Donkin” or the “Project”) on Cape Breton Island.

CEAA concluded in the CSR that “the Project is not likely to cause significant adverse environmental effects when implementation of the proposed mitigation measures, the follow-up program and adherence to conditions and requirements related to the necessary federal permits, authorizations and approvals are taken into account.”

Morien considers this assertion by CEAA as positive for the Donkin Coal Project and looks forward to the results of this third and final public review period.

Morien has a 25% interest in the Donkin Coal Project with 75% partner Xstrata Coal Donkin Management Limited, the managing partner and proponent for the Project. CEAA has initiated a 30-day public review period, with written comments due by May 9, 2013. The CSR is available on the CEAA website.

The CSR provides an overview of the Donkin Coal Project, including its anticipated environmental effects, and provides a summary of public comments from two previous public review periods. CEAA noted that its evaluation of the potential for the Donkin Coal Project to have adverse effects on the environment was based on technical information provided by the proponent, advice from federal and provincial experts, and comments provided by the Mi’kmaq First Nations of Nova Scotia and the public through various consultations.

Morien anticipates announcements will be released by the provincial and federal ministers of the Environment of their respective environmental assessment decisions sometime in Q3 2013.
