VANCOUVER, British Columbia--(BUSINESS WIRE)--Feb. 7, 2003

Development Plans Emphasize Environmental Protection And

Minimizing Disturbance

Miramar Mining Corporation (TSX:MAE)(AMEX:MNG) announced today that its subsidiary, Miramar Hope Bay Ltd. ("MHBL"), has filed a draft Environmental Impact Statement ("EIS") with the Nunavut Impact Review Board ("NIRB") for the development of the Doris North project (formerly known as the Doris Hinge Project) at the Hope Bay project, Nunavut. The draft EIS details the Doris North Project and includes the project description, environmental baseline studies, impact assessments, socio-economic considerations, environmental management plans and reclamation and closure plans which respond to the NIRB guidelines issued in October 2002.

"The filing of the draft EIS initiates the formal review process by NIRB and is a significant step in the permitting process for developing the Doris North Project," said Tony Walsh, Miramar's President and CEO. "This should be the first mine developed where both surface and sub-surface rights are vested with Inuit and the first new gold mine in Nunavut. As a result, the project will generate direct benefits to the Inuit of the West Kitikmeot region and of Nunavut as a whole. We look forward to working with the various stakeholders in Nunavut affected by the proposed development."

The Doris North Project is being reviewed under a NIRB Part 5 review as provided under Article 12 of the Nunavut Land Claims Agreement (NLCA). Miramar expects that NIRB's review of the draft EIS will be completed within 60 days, following which Miramar will prepare the final EIS, that will include responses to matters raised through the NIRB review period. Miramar expects that all other required approvals including a Fisheries Act authorization and a Navigable Waters Act permit, will be coordinated with NIRB. During the 60 day NIRB review period, MHBL will continue its community consultation activities by visiting the communities of influence in the region, presenting the project as outlined in the draft EIS and soliciting comments and concerns. This feedback will be incorporated into the final EIS. Miramar will also be discussing with the Kitikmeot Inuit Association terms and conditions for the project's Inuit Impacts and Benefits Agreement ("IIBA").

"Miramar takes the protection of the environment very seriously. The Doris North project is designed to minimize the impact of the proposed project on the environment," said Mr. Walsh.

Provided there are no delays, Miramar anticipates all necessary permits could be issued towards the end of 2003, allowing major equipment to be ordered soon thereafter. Assuming a positive production decision and necessary financing is obtained, underground development would then commence in mid-2004, with the major equipment and supplies mobilization scheduled for the third quarter of 2004 followed by site construction beginning late in the third quarter 2004. Process plant operations would then begin in the first quarter of 2005.

MHBL looks forward to working with NIRB, the Department of Fisheries and other agencies as we move the Doris North Project forward.
