Miramar Reports Federal Minister Accepts NIRB Report for Doris North
- Permitting Process to Resume for Development of High Grade Gold Mine on the Hope Bay Project -

VANCOUVER — Miramar Mining Corporation (MAE-TSX, MNG-AMEX) today announced that the Minister of the Indian and Northern Affairs Canada (INAC, formerly DIAND) has accepted the report of the Nunavut Impact Review Board (NIRB) issued in August, 2004. On August 16, 2004, Miramar announced that NIRB had recommended to the Minister of INAC that the Doris North project should not proceed on the basis of the current application, identifying five areas where additional information was required. However, in its report NIRB encouraged Miramar to file another application that includes the requested supplemental information.

“The NIRB report invited Miramar to bring the Doris North Project back to the Board for review and indicated that a new application need only focus on five specified areas where additional information was requested,” said Tony Walsh, Miramar’s President and CEO. “Since the NIRB report was issued, we have been working diligently to compile the supplemental information necessary to address these five areas, which work is largely complete. However, we could not move the regulatory process forward until the Minister’s decision was issued. That decision opens the door to Miramar resuming the permitting process. Now we can work with NIRB to establish the Board’s timetable to complete the review of the Doris North project.”

As detailed in the August 16 news release, the five areas identified by NIRB as requiring supplemental information, over and above that already submitted with the initial application, are:

Mitigation and monitoring of wildlife impacts;

Alternatives to the use of Tail Lake as a tailings impoundment;

Tail Lake water quality and water management strategy;

Design and affects of a jetty to be built on the Arctic coast; and

Assessment of socio-economic impacts from the project.

“We are pleased to be able to resume the permitting process for the Doris North project. We believe that Doris North will be just the first step towards significant, long-term production from the Hope Bay belt,” said Mr. Walsh. “Hope Bay is an outstanding gold project that offers potential to catapult Miramar into the ranks of intermediate producers and should generate significant benefits to the local people and Nunavut as a whole. We are confident that we will be able to satisfy NIRB, obtain our permits for Doris North, and thereby grow to establish mutually beneficial relationships with the people of Nunavut for many years to come.”

Process Going Forward

Miramar will announce the schedule for further review after receiving direction from NIRB. Once Miramar has submitted a new application, NIRB will conduct a new review and make a further recommendation to the Minister as to whether the Doris North project should proceed. If a positive NIRB recommendation is obtained and is supported by the Minister, NIRB would then issue a project certificate which would allow the Nunavut Water Board (NWB) to schedule and hold hearings into the granting of a water licence for the project. Assuming a positive NWB decision, the Minister would determine whether to approve the water licence and set the bonding amounts. The project will also need a number of other permits, such as an authorization from the

Department of Fisheries and a foreshore lease from INAC for the jetty. Miramar has taken steps towards obtaining all required permits.
