Coeur Announces Additional High-Grade Drill Results at Cerro Bayo Mine



    COEUR D'ALENE, IDAHO, September 28 /CNW/ - Coeur d'Alene Mines
Corporation (NYSE:  CDE) (TSX:CDM) today announced updated exploration results
at its Cerro Bayo Mine in Chile, where the accelerated drilling program on the
company's large land holdings has continued to return consistently high-grade
silver and gold intercepts close to the mine's processing facilities.

    The recent results are a continuation of the full-year $4.7 million
program in 2007, which through the first six months of the year increased
mineral reserve levels at Cerro Bayo by 51% over 2006 year-end levels. Due to
the high grade nature of the new vein intercepts and their proximity to the
processing facilities, permitting for underground access and future mine
development has started.

    Exploration in the Cerro Bayo district has focused on five new major
veins, discovered over the last four months of this year, located about one
kilometer east of the Cerro Bayo ore processing facility. Nearly 10,000 meters
of core drilling have been completed on Dagny, the parallel Fabiola vein,
which lies about 250 meters to the east of Dagny, and the Dalila and Yasna
veins in the same area. The Coyita vein, located about 300 meters to the east
of Fabiola, is scheduled for initial drilling in October.

    The drill-defined mineralized body at Dagny is now over 600 meters long
and nearly 150 meters in vertical height. Mineralization is still open for
expansion to the southeast. At the parallel Fabiola vein, the drill-defined
body is currently about 350 meters in strike length and about 120 meters in
height. Mineralization is open both to the southeast and northwest and at
depth.

    In addition, results from initial drilling on Yasna and Dalila discovered
ore-grade mineralization in those veins with the most significant results
to-date being 2.43 drill meters averaging 0.96 grams of gold per tonne (g/t)
and 391 grams of silver per tonne in Yasna, and 0.43 drill meters averaging
59.12 grams of gold per tonne and 1,250 grams of silver per tonne in Dalila.

    A list of all analytical results received from recent core sampling
follows.

    Cautionary Statement: Company press releases may contain numerous
forward-looking statements within the meaning of securities legislation in the
United States and Canada relating to the company's silver and gold mining
business. Such statements are subject to numerous assumptions and
uncertainties, many of which are outside the company's control. Operating,
exploration and financial data, and other statements in this document are
based on information the company believes reasonable, but involve significant
uncertainties as to future gold and silver prices, costs, ore grades,
estimation of gold and silver reserves, mining and processing conditions,
construction schedules, currency exchange rates, and the completion and/or
updating of mining feasibility studies, changes that could result from the
company's future acquisition of new mining properties or businesses, the risks
and hazards inherent in the mining business (including environmental hazards,
industrial accidents, weather or geologically related conditions), regulatory
and permitting matters, risks inherent in the ownership and operation of, or
investment in, mining properties or businesses in foreign countries, as well
as other uncertainties and risk factors set out in the company's filings from
time to time with the SEC and the Ontario Securities Commission, including,
without limitation, the company's reports on Form 10-K and Form 10-Q. Actual
results and timetables could vary significantly from the estimates presented.
Readers are cautioned not to put undue reliance on forward-looking statements.
The company disclaims any intent or obligation to update publicly such
forward-looking statements, whether as a result of new information, future
events or otherwise. Donald J. Birak, Coeur's Senior Vice President of
Exploration, is the qualified person responsible for the preparation of the
scientific and technical information in this document. Mr. Birak has reviewed
the available data and procedures and believes the collection of exploration
data and calculation of mineral reserves reported in this document was
conducted in a professional and competent manner. For a description of the key
assumptions, parameters and methods used to estimate mineral reserves and
resources, as well as a general discussion of the extent to which the
estimates may be affected by any known environmental, permitting, legal,
title, taxation, socio-political, marketing or other relevant factors, please
