Miramar Announces $16m 2005 Program for Hope Bay
Project

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 29, 2005) - Miramar
Mining Corporation (TSX:MAE)(AMEX:MNG) -

Goal is to Upgrade Gold Resources to Support Feasibility Study for
Extended & Expanded Production

Miramar Mining Corporation today announced plans for the 2005
exploration season at its 100% controlled Hope Bay project in Nunavut.
The Company intends to spend approximately $13 million on drill programs
designed to upgrade gold resources at the Boston, Doris and Madrid
deposits to technical levels which, if results are positive, would be
incorporated into feasibility studies in 2006. These programs will total
approximately 29,000m of drilling and utilize six to eight drill rigs.
In addition, approximately $2.0 million will be spent on permitting the
Doris North project and community relations, and a further $1.0 million
on work related to preparing the feasibility studies discussed herein.

"Now that we have established substantial gold resources on the Hope Bay
belt, we need to accelerate our efforts to incorporate these resources
into feasibility studies that will support our goal for the phased
development of the belt," said Tony Walsh, Miramar's President & CEO.
"Our objective is to deliver a plan for the integrated development of
the Hope Bay belt in the latter part of 2006. We intend to demonstrate
the opportunity for the significant sustained gold production to follow
on from the Doris North project, a small scale, high grade mining
operation currently in the permitting process."

Drilling at Doris and Madrid has already commenced, while work at Boston
and on other areas of the Hope Bay belt will follow later.

Strategic Objectives

Miramar aims to become an intermediate gold producer through the
integrated development of the Hope Bay belt. In order to achieve this
objective, while minimizing potential dilution and risk to shareholders,
Miramar has developed a phased approach to maximizing gold production
from the Hope Bay belt:



Phase 1: Short Term: Develop a small scale, high grade, low cost,
high return gold mine at Doris North with the objective
of generating significant cash flow, after capital
payback, to advance the subsequent phases while
minimizing equity dilution. Doris North is projected to
produce 155,000 oz of gold per year for two years.

Phase 2: Medium Term: To extend and expand production levels by
developing the higher grade, more accessible areas of
the Boston, Doris and Madrid deposits, with a target
production level of approximately 200,000 oz of gold
per annum, generating cash flow to complete Phase 3.

Phase 3: Longer Term: To further expand gold production by
maximizing the potential of the very large Madrid
deposit, and the remainder of the Boston and Doris
deposits, to generate sustained production in the range
of 350,000 to 400,000 oz of gold per annum.


In parallel with these activities, Miramar intends to continue the
exploration programs at Hope Bay to discover new deposits to contribute
to a sustained intermediate production profile, while conducting
grassroots exploration in cooperation with strategic partners.

2005 Madrid Program

Approximately 18,500m of drilling is planned for the Madrid area, more
than 50% of which is directed towards upgrading the upper portion of the
western Madrid resource, which lies within 250m of surface, to the
indicated category, a confidence level which would be required for
inclusion in a feasibility study for the proposed phase 2 development of
the Hope Bay belt. The remaining drilling will be focussed on continuing
to expand the Madrid resource, and evaluating opportunities to identify
potential new resource areas within the core 2km strike of the Madrid
system.

"Over the past three years, the Madrid deposit has emerged as the
largest identified gold system on the Hope Bay belt," said Mr. Walsh.
"Given the substantial thicknesses of mineralization identified, we
believe Madrid offers excellent potential for the development of a
large-scale, sustained mining operation supplemented by higher grade
feed from other deposits on the belt. Our near-term objective is to move
a significant portion of the Madrid resources towards inclusion in
economic studies that support (1) the extension of the operating life of
the proposed facilities at Doris North, and (2) the expansion of the
overall production level during Phase 2. Ultimately, we believe that,
when blended with the higher grade resources from the rest of the belt,
the Madrid area will offer a very substantial production base from which
to reach our goal of intermediate producer status during Phase 3."

2005 Doris Central Program

Drilling prior to 2004 in the Doris Central area, located approximately
1km south of the Doris North project defined an indicated resource of
201,000oz at a grade of 14.9g/t gold and an additional inferred resource
of 59,000oz at a grade of 16.0g/t gold. Approximately 4,500m of drilling
are planned to upgrade the confidence level of the current Doris Central
resource to the indicated category and to potentially expand the overall
resource in this area. Doris Central could then be included in a
feasibility study for development of the wider Hope Bay belt providing,
along with the Boston deposit, higher grade feed to blend with the bulk
tonnage potential of the Madrid deposit.

Other 2005 Programs

Details of the 2005 Boston program have not been finalized, but are
expected to focus on continuing to upgrade the confidence in the Boston
resource as part of the on-going work to support a future feasibility
study on the wider Hope Bay resources. Approximately 6,000m of drilling
have been set aside to assist in: defining stope outlines; upgrading
inferred resources to the indicated category within mining areas; and
potential high impact resource additions. Limited belt-wide exploration
activities will focus on meeting the assessment work requirements in
order to maintain the Hope Bay property in good standing. Maximus
Explorations Inc., which has an option to earn an interest in the
Eastern Contact and Twin Peaks areas of the Hope Bay belt, is also
expected to carry out an exploration program in the areas it has under
option.

Feasibility Studies

The purpose of the 2005 work will be to upgrade the resources at the
Doris Central, Madrid and Boston deposits to a level which could be
included in a feasibility study. Miramar will assess the results of the
2005 work to determine how to proceed with future feasibility studies in
support of the Phase 2 medium term objective.

Permitting

On February 18, 2005 Miramar announced that it had filed its preliminary
project description for the Doris North project with the Nunavut Impact
Review Board. NIRB has written to the Minister of INAC requesting
direction to conduct a review of the project in accordance with Part 5
of the NLCA. Miramar is committed to working with all stakeholders to
strive for success in permitting the Doris North project.

Hope Bay Resources

As announced February 25, 2005, the updated resource estimate for the
Hope Bay belt that takes into account the 2004 drilling is summarized
below. Miramar's objective for its extended and expanded production
scenario, which is the subject of on-going studies, is to allow blending
of these various sources of potential feed through an integrated
approach to development that could result in an average grade close to
the overall average grade of the Hope Bay belt, in the range of 7-9g/t
gold.

Quality Assurance

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.

Miramar Mining Corporation

Miramar is a Canadian gold mining company that controls Hope Bay which
contains one of the largest, best-grade undeveloped gold deposits 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's goal is to build an intermediate gold production profile by
maximizing the development potential of the substantial gold resources
defined on the Hope Bay belt. To this end, Miramar believes that the
cash flow generated by the proposed Phase 1 Doris North mine could be
used as a springboard to fund the phased development of a long life,
larger scale mining operation eventually producing in excess of
350-400,000oz of gold per year. Conceptually, Miramar believes the Doris
Central, upper Boston and western Madrid resources might provide
sufficient reserves to support second phase long life operation,
blending bulk tonnage Madrid production with higher grade feed from
other deposits. Subsequently, a further expansion could be warranted to
maximize the enormous potential of the remaining Madrid resources, and
thereby achieving intermediate producer status. Miramar's goal is to
have Doris North as the infrastructure centre for the entire Hope Bay
belt, thereby minimizing the overall environmental impact and the
capital requirements, and optimizing the return on future development
areas. In parallel with these development activities, Miramar plans to
increase the total gold resources on the belt through the expansion of
the known deposits and discoveries of new ones.

A decision to proceed with mining at Doris North would be subject to the
availability of permits and financing and a variety of other
contingencies. Any plans for extending and expanding the life of the
Doris North operation would be subject to the successful completion of
additional drilling, economic studies and permitting procedures.
