Miramar Reports Further Progress in Outlining Pit Possibility at Madrid
–Significant drill results at Madrid with intercepts of 3.2g/t Au over 164m and 9.1 g/t Au
over 38.3m

VANCOUVER — Miramar Mining Corporation today announced more significant results from the 2006 drilling program at its Hope Bay Project in Nunavut. The program is focussed on the Madrid district, where drills were testing for newly defined mineralization that would enhance the possibility of a large pit concept at Madrid. The latest shallow Suluk infill drilling as well as drilling along the southern extension of Suluk has exceeded expectations.

Miramar embarked on the 2006 exploration campaign at Hope Bay with the objective of defining a second phase of production on the belt following the proposed Doris North Project which is now in the permitting process. The second phase options include two scenarios: a) a 350,000 ounce per year open pit/underground operation; and b) a large pit concept.

Based on previous modeling of the deposits, preliminary open pit designs in the Madrid area (which includes the Naartok, Rand and Suluk deposits) illustrated the potential for two or more small shallow pits to exploit the Madrid resource. Modelling completed at the end of 2005 indicated the potential for much larger scale open pit operations. Therefore, in an effort to maximize the economics of any potential open pit, 2006 drilling was planned and is ongoing with the objective of determining the continuity of mineralization between these deposits (the gaps), as well as indicating the previously identified mineralization extends to depth. This will determine the optimal through put for any contemplated mill.

The winter program focused on completing drilling off the lake which primarily tested the Suluk targets. Drilling to date has returned significant results which infilled and expanded the previously modeled mineralization at Suluk. Some of the more significant results include 06PMD428 which returned 28.0 m grading 11.28 g/t gold and 06PMD427 intersected a broad mineralized interval of 3.2 g/t Au over 164m including two intervals of 51.2 m grading 3.3 g/t gold and 52.5m grading over 4.6 g/t gold. Extending mineralization to depth at Suluk and finding mineralization in the gaps at Madrid could possibly support a deeper wider pit, which could increase tonnage and potentially lower costs enhancing the economics of any contemplated large pit concept.

“This year’s primary focus is now to determine the size of the possible second phase of production at Hope Bay,” said Tony Walsh, Miramar’s President and CEO. “With the work done and the results received to date, it is evident that at Madrid, the work needs to now focus on size. With a view to determining the optimal mining and milling capacity, drilling will be completed in the 2006 program to determine tonnage potential. Miramar intends to complete studies by the end of 2006 to outline various capacities of potential production anchored at Madrid from which to choose the best option”.

2006 Madrid Program
The goals of the campaign are to:

•

seek to expand existing resources to enhance project economics

•

upgrade resources by infill drilling

•

aggressively seek to extend the Madrid system

•

complete initial drilling to determine the potential size of a Large Pit Scenario

A program of ice based infill and expansion drilling around the key Madrid zones has been underway since mid-March to meet these objectives. A total of 26,500 metres in 83 holes has been completed to date with results available a further 22 holes. The first 32 Madrid holes were reported on Miramar news release dated May 25, 2006, which can be found on the company website at www.miramarmining.com. Results for the new holes are presented below.

Suluk and South Suluk
A project of infill drilling the upper 250m of the Suluk resource targeting the upper 100 meters and strike extensions to the north and south has been completed. Drilling has successfully identified the Suluk mineralization extends northwards towards the Rand and Naartok deposits indicating continuity of the mineralizing system between the resource areas. Additionally drilling has also extended the Suluk mineralization southwards with all holes returning results equivalent to or better than grades and thicknesses expected based on data from surrounding holes. Examples include 06PMD428 in the shallow northern portion of the deposit returning 9.1g/t Au over 38.3m and 06PMD427 at the south end of the resource area intersected a broad mineralized interval of 3.2 g/t Au over 164.2m including two intervals of 3.3 g/t Au over 51.2 m and 6.0 g/t Au over 52.5m.

Rand Gap Areas
Drilling at Rand infilled between wide spaced holes targeting higher grade zones, and extended mineralization on strike and down dip into gap areas between Naartok, Rand and Suluk. This drilling has demonstrated that the mineralizing system with low to moderate values has continuity between our resource areas and in the process has also intersected shallow zones of significant grades and thicknesses.

Some significant results to date include 06PMD430 returning 2.9 g/t gold over 14.0m and 06PMD426 returning 3.6 g/t Au over 12.6m.

Naartok Expansion and Infill
Drilling at Madrid has shifted to the Naartok-Rand gap and Naartok East deposits. Initial drill targets are larger stepout holes utilizing two to three core drills. The Naartok drilling will expand to five to seven drills in mid July. Results from this drilling are pending.

2006 Boston

The Boston B4 evaluation is ongoing with four holes completed to date. The B4 zone is a sparsely drilled vein system which is parallel to the main B2 and B3 zones that comprise the bulk of the Boston resource. This project is targeting higher grade intercepts from previous drilling is areas with greater than 200 metre drill spacing. Results from these initial holes are pending.

Miramar Mining Corporation

Miramar is a Canadian gold company that controls the Hope Bay project, the largest undeveloped gold project in Canada. The Hope Bay project extends over 1,000 sq. km. and encompasses one of the most prospective undeveloped greenstone belts in Canada. Miramar aims to become an intermediate gold producer through the integrated development of the Hope Bay belt. Any production at Hope Bay is subject to positive feasibility studies, permitting and regulatory approval, the availability of financing and other contingencies.

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements set out in National Instrument 43-101 and reviewed by John Wakeford, P. Geo. Vice President, Exploration for Miramar Mining Corporation, and the Qualified Person for the Company as set out in NI 43-101. The analytical method for the gold analyses is gravimetric assay done by ALS Chemex Laboratories in North Vancouver with metallic screen assays for all samples assaying over 20 g/t gold. Check assays are completed by TSL in Saskatoon.

Assay intervals reported are drill core lengths. Geologic interpretation of drill results is underway. However, it is estimated that true widths would generally be at least 70-80% of reported core lengths.
