                                                                        2000-16

                       HECLA ENTERS INTO AGREEMENT TO SELL
                         BALL CLAY AND KAOLIN DIVISIONS
                              FOR IMMEDIATE RELEASE
                                November 20, 2000

     COEUR D'ALENE, IDAHO - Hecla Mining Company (HL & HL-PrB:NYSE) today
announced it has entered into an agreement to sell its wholly owned subsidiary,
Kentucky-Tennessee Clay Company, to Zemex Corp. of Toronto, Canada, for a price
of $68 million. Hecla plans to sell its feldspar subsidiary separately.

     Arthur Brown, Hecla's chairman, president and chief executive officer,
said, "This is a case where the parts are greater than the whole. We can realize
a larger return overall by selling the feldspar segment separate from the ball
clay and kaolin divisions. We already have interest in the feldspar business
from another party and, in fact, have commenced negotiations on that part of the
transaction. However, we wanted to make sure we had a commitment for the
purchase of the larger portion first."  Brown said he is pleased with the
purchase price of the ball clay and kaolin operations and expects to close the
transaction by the end of January 2001. He continued, "I feel we received good
value for a good asset. Furthermore, Zemex has indicated it expects to retain
K-T Clay's employees, and it is important to me to know that our people will
have continued employment opportunities."

     Hecla has previously announced it intends to use proceeds from the sale of
Kentucky-Tennessee Clay Company to pay down current bank debt of $55 million
coming due next April and for general corporate purposes. The company
anticipates the sale of K-T Clay will enhance its potential for future precious
metals acquisitions or expansions, as well as eliminating most of the company's
bank debt.

     Brown said, "This move refocuses us on our historical silver producing
heritage. During its 110-year history, Hecla has been well-known as one of the
United States' premier silver producers. We have increased our silver production
more than fourfold over the past five years in anticipation of a future increase
in the price of silver. I think we could be in the `darkest before the dawn'
period of this low silver price cycle. We believe the fundamentals of supply and
demand and silver's current deficit situation are bringing us closer to the time
when we may see a sustained increase in the price of silver. Demand for the
metal continues to increase each year, and our position as a producing silver
company puts us in position to benefit from that price increase when it occurs.
Becoming a pure-play precious metals company is designed to benefit our share
price, as we believe some investors did not give us full value in the past for
our industrial minerals subsidiaries."

     Hecla Mining Company mines silver and gold at three underground mines in
Alaska, Idaho and Venezuela. Precious metals exploration projects and properties
are located in the vicinity of the existing mines, as well as the promising
Saladillo silver/gold exploration property in central Mexico. The company
expects to produce approximately 8 million ounces of silver and about 130,000
ounces of gold in 2000.

     Kentucky-Tennessee Clay Company, headquartered in Nashville, Tennessee, is
a major producer of ball clay and also mines kaolin in the southeast United
States. K-T Clay also operates a clay processing plant in Mexico. Its products
are marketed mainly to manufacturers of ceramics products.
