Miramar Receives Doris North Project Certificate. Permitting Moves to the Next Phase.

VANCOUVER -- Miramar Mining Corporation today announced that it has received the Doris North Project Certificate from the Nunavut Impact Review Board, (“NIRB”) and that the first phase of proposed production at Hope Bay has officially moved into the regulatory process.

In March 2006, the NIRB completed its review of the environmental impact assessment of the Doris North Project and recommended to the Minister of Indian and Northern Affairs Canada (“INAC”) that the Project should be given approval to obtain the required permits for construction and operation. In a letter dated July 28, 2006, the Minister of INAC accepted NIRB’s recommendation. The Minister’s letter also advised that the other federal departments with jurisdictional responsibility in relation to Doris North have concurred with this decision.

The Project Certificate received from NIRB on September 15, 2006 includes terms and conditions to be implemented by various regulatory agencies in accordance with their guidelines for issuing licences, permits and authorizations for Doris North. The Project will need a number of permits, authorizations and leases, and steps towards obtaining these are underway.

“We are delighted that we are now through the environmental assessment phase of the project and to be working with the various regulatory agencies to obtain the permits necessary for construction and operation of Doris North. The issuance of the Project Certificate signifies that the federal government and the NIRB have agreed that the project can proceed subject to licensing and permitting conditions. Now we must work with the various agencies to demonstrate that the project meets all guidelines and regulations. We are excited about what will potentially the first new gold mine in Nunavut.” said Tony Walsh, Miramar’s president and CEO.

Subject to timely progress in obtaining necessary permits, Miramar plans to start procurement and mobilizing of equipment with the intention of moving as much material possible in the shipping season of 2007. Dependent on receipt of all final licences, permits and authorizations, Miramar hopes to commence mining at Doris North in mid 2008
