Exhibit 99


Hecla's Gross Profit Nearly Doubles During First Quarter,
Silver and Gold Production Cash Costs Remain Low

    Business Editors

    COEUR D'ALENE, Idaho--(BUSINESS WIRE)--May 4, 2004--Hecla Mining
Company (NYSE:HL) today reported net income of $6.2 million for the
first quarter of 2004, compared to net income of $6.7 million for the
first quarter of 2003. However, last year's net income was aided by a
$4 million legal settlement and a $1.1 million positive cumulative
effect of change in accounting principle. Net income for the first
quarter of this year is a direct result of an over 90% increase in
gross profit from operations compared to last year.
    Improved sales, gross profit and operating income compared to the
same period last year were due to higher silver, gold, lead and zinc
prices, as well as decreased silver production cash costs and
increased gold production. Hecla's cash costs for gold production also
remain low, at an average total cash cost per ounce of $142, making it
one of the lowest-cost gold companies. As a result of these factors,
gross profit increased from $7 million in the first quarter of 2003 to
$13.4 million in the first quarter of 2004.
    During the first quarter, approximately 307,000 outstanding shares
of Series B preferred stock were exchanged for approximately 2.4
million shares of common stock. As a result of these successful
exchanges, approximately 158,000 shares of preferred stock remain
outstanding. Although the transaction does not impact the balance
sheet or net income, the company is required to report a non-cash
dividend expense of approximately $10.9 million on the income
statement, which is the primary reason for a "basic and diluted loss
per common share available to common shareholders" of 4 cents per
share during the first quarter.
    Hecla's President and Chief Executive Officer, Phillips S. Baker,
Jr., said, "Hecla continues to deliver low-cost gold and silver
production. Certainly, the increased precious metals prices allow us
to generate remarkable increases in gross profit, but our goal is to
remain one of the lowest-cost gold and silver producers with an eye on
growth, no matter what the prices may do. I'm very pleased with both
our operational performance and our progress in our expanded
exploration program so far this year. With the prospects and
properties we have in hand now, Hecla can grow dramatically over the
next few years while maintaining a conservative balance sheet and high
returns."

    Operations

    In the first quarter, Hecla produced 2.1 million ounces of silver
at an average total cash cost per ounce of $1.43, maintaining its
position as the lowest-cost primary silver producer. Gross profit from
silver operations more than doubled to $9.6 million in the first
quarter of 2004 compared to 2003, thanks to the dramatic increase in
silver price compared to a year ago. The company also produced 55,817
ounces of gold, with 37,547 ounces coming from Hecla's primary gold
operating unit, La Camorra, at an average total cash cost per ounce of
$142. Gross profit from La Camorra increased 37% over the same quarter
a year ago, from $2.8 million to $3.8 million in the first quarter of
this year.
    Baker said, "We continue to focus on growth, with a goal of
doubling our gold production by the end of 2008. And in about 18
months, we should see an increase in silver production, as development
of the new level of the Lucky Friday makes it possible for us to
return to full production of 4 million ounces per year at that mine."
    During the first quarter, the San Sebastian silver operation in
central Mexico produced 857,100 ounces of silver and 11,474 ounces of
gold. The significant gold by-product at San Sebastian allowed the
mine to produce silver at the extremely low cost of negative 44 cents
per ounce during the first quarter of 2004, compared to negative 7
cents per ounce in the first quarter of 2003. Mining this year is
taking place in a lower-grade area of the mine, so silver production
decreased from a year ago because the grade of silver was
approximately 25 ounces per ton during the first quarter of 2004
compared to 32 ounces per ton during the first quarter of last year.
However, with grades of 25 ounces of silver per ton and nearly
one-third of an ounce of gold per ton, San Sebastian continues to be a
very high-grade mine.
    The Greens Creek mine, located near Juneau, Alaska, is a joint
venture with Kennecott Greens Creek Mining Company, a subsidiary of
Rio Tinto. Hecla holds an approximate 30% interest in the operation.
In the first quarter, Greens Creek produced 744,967 ounces of silver
and 6,743 ounces of gold for Hecla's account, at an average total cash
cost of 98 cents per ounce of silver. Increased gold, zinc and lead
prices favorably impacted Greens Creek's cash costs, as those metals
are important by-products at that mine. Greens Creek's cash costs per
ounce decreased 41% compared to the first quarter of 2003.
    The Lucky Friday silver mine is located in northern Idaho, and
Hecla has been operating this mine since 1958. During the first
quarter, Lucky Friday produced 483,418 ounces of silver at an average
total cash cost of $5.44 per ounce, compared to $4.47 per ounce a year
ago. However, due to the increases in silver and lead prices, Lucky
Friday's sales and income from operations both increased significantly
compared to a year ago. The mine's costs have increased because the
access to ore continues to get further away from the 4900-level drift,
resulting in longer haulage times. The decision has also been made to
mine lower-grade material because of the increased metals prices. This
increases cash flow, but it also results in increased cash costs. Once
the development of the 5900 level is complete, Lucky Friday's cash
costs are expected to decrease to well below $5.00 per ounce of silver
because haulage lengths will decrease. In addition, the mine will be
able to ramp back up to full capacity of approximately 4 million
ounces of silver per year. Work is progressing as scheduled on the
5900-level drift, with four crews working 24 hours a day. Miners have
advanced approximately 450 feet to date on the drift, which leads from
the Lucky Friday Silver Shaft and will run approximately 5,465 feet to
the expansion area where about 28 million ounces of silver resource
have been identified. The schedule calls for completion of the drift
and commercial production from the new level by the end of 2005.
    Hecla's primary gold producer is the La Camorra unit, located in
eastern Venezuela. During the first quarter of 2004, La Camorra
produced 37,547 ounces of gold at an average total cash cost of $142
per ounce. Production increased compared to the same period last year,
with slight increases in tonnage and grade. The ore grade mined in the
first quarter was 0.84 ounce of gold per ton, compared to 0.82 ounce
of gold per ton a year ago. Work continues on construction of a
2,000-foot-deep production shaft at La Camorra, where the ore is
currently hauled out of the mine via a decline ramp and trucks.
Although La Camorra is a very low-cost mine, as the mine gets deeper,
haulage times and costs increase. The production shaft will allow more
efficient removal of the ore. Completion of shaft construction is
scheduled for the end of 2004, with construction costs estimated at
$12 million.
    As previously reported in a March 2004 news release, approximately
5,000 ounces of gold worth about $2 million was provisionally withheld
from export from Venezuela, pending an administrative review of export
documentation. Hecla has provided all documentation necessary to
satisfy the review and received a court order directing the release of
the gold back to the company, subject to further court proceedings. In
the meantime, La Camorra continues normal operations, and all
subsequent gold shipments have been exported out of Venezuela on
schedule.

    Exploration

    Hecla spent about $2.4 million on exploration in the first quarter
of the year, and is projecting to spend approximately $12 million to
$15 million on exploration in 2004. Progress on the Mina Isidora
deposit in Venezuela is especially promising, and earlier in the year,
Hecla reported a proven and probable reserve there of 327,000 ounces
of gold. A decision on developing the deposit is expected in the near
future. An ongoing deep directional drilling program at Hecla's La
Camorra mine has also been successful, with one hole intersecting ore
grade material at a depth of 3,300 feet, more than 1,300 feet below
the current mining area. The deposit now appears to be continuing at
depth in a more easterly direction, and several holes drilled into
that area show ore grade material as well. In addition, several
drilling programs are planned on Hecla's very prospective land
position surrounding the La Camorra mine and on the Block B
concessions, where Mina Isidora is located.
    About $1.2 million was spent in the first quarter on exploration
surrounding the San Sebastian mine in central Mexico. Geologists
remain convinced of the long-term potential on the 190-square-mile
property position, which is located on trend with some of the oldest
and richest silver mines in the world. An aeromagnetic survey and a
geologic characterization study have now been completed on the entire
concession. Thousands of soil samples were collected during the
quarter, and geochemical results have been received on about half of
the samples. Anomalies in gold and silver have been identified to the
west, north and east of the Francine vein. Five exploration drill
holes were completed during the quarter testing for a second, separate
and lower mineral band below the currently identified reserve and
resource area. Visual indications are encouraging; however, assays are
pending and the program is in its very early stages.
    Baker said, "The exploration results we're beginning to get are
very exciting and we're moving forward as quickly as we can. It takes
time to identify and explore targets and eventually develop them into
a mine, but we believe that by having our land positions located in
these world-class mining districts, we'll be very successful long-term
with these programs. We expect to be exploring and mining for a long
time to come in these districts."
    At the Hollister Development Block gold exploration project in
northern Nevada, Hecla reported in the first quarter that it received
notification of approval of the federal permits needed from the Bureau
of Land Management (BLM), subject to a public comment period. The
project is an earn-in to a joint venture with Great Basin Gold. The
BLM has also reviewed the bonding calculations and is expected to
complete the bond adjudication process soon. Once an acceptable
interim arrangement for property access and work authorization is
reached (with a land transfer expected in the future), Hecla can begin
site preparation work, with commencement of actual underground
exploration ramp construction expected this summer.

(1) Costs per ounce of gold are based on the gold produced by the
    Venezuela segment only.

(2) Cash costs per ounce of silver or gold represent non-U.S.
    generally accepted accounting principles (GAAP) measurements that
    management uses to monitor and evaluate the performance of its
    mining operations. We believe cash costs per ounce of silver or
    gold provide an indicator of profitability at each location and on
    a consolidated total, as well as a meaningful basis for which to
    compare other mining companies and other mining operating
    properties.

(3) Costs per ounce of silver are based on production from both the
    Mexico and United States segments. The United States segment
    includes both the Greens Creek unit and the Lucky Friday unit.
