Miramar Comments on Environment Canada News Release

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 30, 2006) - Miramar Mining Corporation (TSX:MAE)(AMEX:MNG) ("Miramar") today responded to the News Release disseminated by Environment Canada relating to charges laid against Miramar and four related companies in relation to a fuel spill that occurred at the Hope Bay project in June, 2004.

The existence of the spill which occurred two years ago and possibility of charges has been disclosed in Miramar's Annual Information Form public filings in 2005 and 2006. The incident was also addressed in the Doris North Final Environmental Impact Statement filed with the Nunavut Impact Review Board in the recent environmental assessment of the Doris North project.

"The 2004 spill which occurred on Inuit owned land was a very unfortunate accident, however, it was cleaned up promptly and effectively without any significant residual adverse effect on the environment and to the satisfaction of the land owners," said Tony Walsh, President of Miramar. After the spill, Miramar conducted an audit of environmental procedures at Hope Bay and adopted more stringent fuel handling and containment procedures to prevent a similar occurrence from happening in the future. "As a result of implementing these strict procedures, there have been no significant environmental occurrences at the Hope Bay project in the two years since the spill occurred, and work has continued at Hope Bay unimpeded. Miramar continues to strive to achieve the highest environmental practices," said Mr. Walsh.

A Miramar subsidiary, Miramar Hope Bay Ltd., is the sole operator of the Hope Bay project and Miramar will be taking steps to have the charges that have been laid against companies other than Miramar Hope Bay Ltd withdrawn.

Miramar does not expect that if Miramar Hope Bay Ltd. is found guilty of the offences, the amount of a possible fine would have a material impact on the financial position of Miramar.
