       Hecla Reports Second Quarter & First Half 2004 Earnings;
                  Cash Flow and Gross Profit Increase

    COEUR D'ALENE, Idaho--(BUSINESS WIRE)--Aug. 3, 2004--Hecla Mining
Company (NYSE:HL) (NYSE:HL-PrB) today reported net income of $2.7
million, or 2 cents per share, for the second quarter of 2004,
compared to net income of $2.5 million, or 2 cents per share, for the
second quarter of last year. Cash flow from operations was the highest
in 10 years, increasing 44% from the second quarter of last year.
Gross profit was $10 million, up slightly from the second quarter of
2003.
    In the first half of 2004, Hecla reported net income of $8.9
million, compared to $9.3 million in the same period of 2003. The
first half of 2003 benefited from a one-time gain of $4 million as the
result of a litigation settlement with Zemex Corporation and a $1.1
million positive cumulative effect of a change in accounting
principle. Excluding these items, Hecla's net income increased
significantly from the 2003 period. As a result of the company's plan
to grow its ore reserves and resources for the future, Hecla's first
half 2004 results included an expanded exploration program in which
expenditures increased approximately $1 million compared to the same
period last year. Gross profit increased by 41% and cash flow from
operations increased 29% for the first half of the year compared to
the same period last year.
    Hecla President and Chief Executive Officer Phillips S. Baker,
Jr., said, "This is a continuation of the excellent operating
performance Hecla's assets are able to deliver. We have very low costs
of production in both silver and gold, and plan to keep using our cash
flow to fund the expanded exploration program and look for potential
acquisitions. Our exploration projects are in excellent mining
districts and our results continue to be encouraging. We are in the
best position ever for long-term growth."

    GOLD OPERATIONS & EXPLORATION

    Hecla produced 109,197 ounces of gold in the first half of 2004,
at a total average cash cost per ounce of $152. Hecla is on track to
produce approximately 215,000 ounces of gold for the year, as
previously estimated, at costs in the lowest quartile in the industry.
    The Venezuelan gold operation produced 74,131 ounces in the first
half of 2004, with 36,584 ounces of gold coming in the second quarter.
Higher cash costs compared to the same period a year ago are primarily
due to a 25% increase in labor costs, which is in line with the
inflationary adjustment done annually. La Camorra recently
successfully completed and signed a 28-month labor contract.
    The ore grade in the first six months of the year improved by 8%,
to 0.81 ounce of gold per ton at this underground gold mine. La
Camorra exploration continues to be positive. A series of deep
exploration intercepts on the Main Zone vein at La Camorra show assays
indicating ore grade mineralization as far as 1,000 feet below the
current development levels.
    Excavation of the shaft at La Camorra is approximately 60%
complete and foundations for the hoist are being poured. The shaft,
which has been re-engineered to include upgrades to the hoisting
system and additional ventilation improvements, is expected to cost
about $15 million, and will be just under 2,000 feet deep. The haul
times to the surface by truck get longer as the decline ramp gets
deeper, so shaft access to the ore body will help keep costs down. The
shaft is scheduled to be fully operational in the first quarter of
2005.
    About 5,000 ounces of gold previously withheld from export in
Venezuela due to an administrative review have been released and
exported from the country. Hecla fully cooperated with Venezuelan
authorities throughout the administrative process and the outcome was
as expected, with Hecla judged in compliance with all export and
regulatory requirements.
    During the second quarter, Hecla announced a development decision
at the Mina Isidora gold mine on the Block B lease in eastern
Venezuela. Site preparation work has been completed and Hecla is in
the process of starting the underground decline ramp. Full commercial
production of between 75,000 and 115,000 ounces of gold annually at
cash costs of $150 to $180 per ounce is expected to be achieved by the
second quarter of 2006. Relatively little capital is needed to develop
the mine, because construction of a processing mill will not be
necessary. The ore will be trucked about 70 miles south to Hecla's La
Camorra mill. The development budget is approximately $30 million.
    Additional exploration on other Block B targets is showing good
results on drilling less than 1,000 meters to the northeast of Mina
Isidora. Baker said, "We have an excellent land position in this
historically rich gold mining district. I expect over time to see an
expansion of Mina Isidora and the development of other projects in
this area."
    At the Hollister Development Block gold exploration project in
northern Nevada, Hecla continues to await an acceptable arrangement
for property access and work authorization in order to begin the
underground exploration ramp construction. The project is an earn-in
to a joint venture with Great Basin Gold. The project has received all
necessary state and federal permits.

    SILVER OPERATIONS & EXPLORATION

    Hecla produced 3.9 million ounces of silver during the first half
of 2004, with 1.8 million ounces mined in the second quarter. Hecla
has some of the lowest-cost silver production in the world,
contributing to the very low average total cash cost during the first
half of the year of $1.57 per ounce, which is even lower than in 2003.
Hecla expects to maintain a similar level of production in the second
half, resulting in a total of approximately 8 million ounces of silver
production for 2004.
    Despite lower ore grades resulting in decreased production, San
Sebastian maintained its position as one of the lowest-cost primary
silver mines in the world. As the currently known productive life of
the Francine and Don Sergio veins reaches its end in 2005, Hecla
expects production to decline and costs to increase until the next ore
body is put into production.
    Exploration aimed at finding the next rich deposit on Hecla's
extensive Mexican property to replace San Sebastian's production
continues to be encouraging. Out of 20 holes drilled directly below
the Francine vein into another, deeper deposit, six have indicated ore
grade material. Another 15 to 30 deep holes are planned in order to
further identify the system and potential deposit.
    Other areas in Hecla's nearly 200-square-mile property position in
Mexico are targeted for exploration as well. A drilling program has
begun in the Cerro Blanco area, with a trenching program to follow up
on geochemical and geophysical anomalies underway just to the west of
the Francine vein.
    Baker said, "Our 2004 exploration program of $5 million on our
Mexican property is in full swing, and we've turned up a number of
good results in multiple areas. The property is so large and the
geology is so good, it's just a matter of time before we'll be able to
find another deposit to replace the Francine and Don Sergio veins.
Meanwhile, increased production at the Lucky Friday mine in Idaho will
come on line in late 2005 to help make up for any temporary decrease
in silver production in Mexico."
    Progress on the 5900-level development at the Lucky Friday silver
mine in northern Idaho is slightly ahead of schedule. The drift has
advanced 2,100 feet as of August 1. The mile-long drift, which is more
than a mile under the surface, will allow Hecla to access an
additional 28 million ounces of silver over the next seven years,
doubling annual production from approximately 2 million ounces of
silver to 4 million ounces.
    Meanwhile, production continues from the 4900-level at the Lucky
Friday mine, where costs have risen somewhat because of a decision to
mine lower grade material, which is still profitable at today's
prices. In the first six months of this year, Lucky Friday has
produced more than 1 million ounces of silver at an average total cash
cost of $5.14 per ounce. Once mining begins from the 5900-level, cash
costs are expected to be under $4.50 per ounce of silver.
    The Greens Creek silver mine in Alaska, in which Hecla holds an
approximate 30% interest, contributed 1.4 million ounces of silver to
Hecla's account during the first six months of 2004, at a very low
average total cash cost per ounce of 77 cents. Compared to the same
period last year, Greens Creek silver production decreased due to a
lower silver ore grade. The area currently being mined is higher in
base metal content and lower in silver grade. Sales of products in the
second quarter at Greens Creek decreased from $7.9 million in 2003 to
$4.3 million in 2004, due primarily to timing of concentrate
shipments.

    OTHER

    Hecla has recently received a favorable decision in Idaho District
Court relating to a lawsuit brought against the company by
Independence Lead Mines Company. Independence had alleged a breach of
contract in a 1968 agreement between the companies, which gave Hecla
the sole right and responsibility to operate the expansion area of the
Lucky Friday mine (also known as the Gold Hunter area). Independence
has an 18.52% net profits interest in the property. The matter went to
trial in March. On July 19, the judge ruled that Hecla had operated
the mine in a prudent and responsible manner and denied all of
Independence's claims.
    Hecla is pleased to announce the appointment of Russell D. Alley
as the new General Manager of Minera Hecla. He will be responsible for
operating the San Sebastian mine and the Velardena mill, as well as
supervising exploration efforts on Hecla's Mexican property position.
After a transition period, the former General Manager, Scott Hartman,
returns to the Hecla corporate headquarters in Coeur d'Alene, Idaho,
where he will be Co-General Manager of Technical Services. Hartman was
the General Manager of the Mexican operations for three and a half
years. Alley was most recently the Chief Executive Officer for Konkola
Copper Mines (Zambia) and formerly held positions as General Manager,
Vice President and President of mines in Chile and Peru. He holds a
metallurgical engineering degree from the University of Arizona and an
M.S., Management, from Troy State University, Alabama.
    Hecla's balance sheet remains strong, with $108 million in cash
and short-term investments and just $2.8 million dollars in debt.
    Hecla Mining Company, headquartered in Coeur d'Alene, Idaho, mines
and processes silver and gold in the United States, Venezuela and
Mexico. A 113-year-old company, Hecla has long been well known in the
mining world and financial markets as a quality silver and gold
producer. Hecla's common and preferred shares are traded on the New
York Stock Exchange under the symbols HL and HL-PrB.

(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.
