Exhibit 99.1 Hecla Reports Lowest Silver Cash Cost Ever, and Announces 200% Increase in Earnings from Operations Compared to First Quarter Last Year COEUR D'ALENE, Idaho--(BUSINESS WIRE)--May 2, 2007--Hecla Mining Company (NYSE:HL) today reported net income of $8.1 million, or 7 cents per common share, on revenue of $53.1 million in the first quarter of 2007. First quarter production was 1.6 million ounces of silver and 36,330 ounces of gold, with all operations solidly on track to meet production estimates for the year of 6 million ounces of silver and 140,000 ounces of gold. The company's income from operations for the first quarter increased more than 200% compared to income from operations in the first quarter of 2006 of $2.5 million. First quarter 2006 net income results of $38.4 million also included a gain of $36.4 million attributable to the sale of investments. Hecla Mining Company President and Chief Executive Officer, Phillips S. Baker, Jr., said, "This is the start of another very profitable year for Hecla. Our Lucky Friday and Greens Creek silver mines are doing particularly well, with a combined average total cash cost for the first quarter of negative $1.12 per ounce due in part to robust prices for our by-product metals of zinc and lead, as well as the high quality of our ore bodies. Of course, it is our employees who make it all happen." The quarter also included cash generation by operating activities before exploration and pre-development expense of $21.4 million, compared to $4.6 million in the same period last year. Gross profit in the first quarter, primarily from the silver operations, was $16.4 million, compared to $11.7 million in the first quarter of 2006. Cash and short-term investments totaled $111.3 million at March 31. Since the end of the quarter, that total has been boosted by the receipt of approximately $45 million from the sale of the Hollister Development Block in April. FIRST QUARTER 2007 HIGHLIGHTS -- Net income of $8.1 million, or 7 cents per common share -- 1.6 million ounces of silver produced at an average total cash cost of $(1.12) -- 36,330 ounces of gold produced, with 31,479 ounces mined at the La Camorra Unit at an average total cash cost of $475 -- Sale of Hecla's interest in the Hollister Development Block exploration project announced, with completion of the transaction occurring in the second quarter -- Hecla remains debt free, with significant cash and short-term investments on hand -- Encouraging exploration results received from the first hole drilled upward into the Lucky Friday "gap" area -- Pre-feasibility to study expansion potential at Lucky Friday underway -- Average prices for silver, gold, lead and zinc all significantly higher than one year ago Baker said, "In 2006, we reported the highest earnings and lowest cash costs for silver in the history of our 116-year-old company. We now have the potential to set another record in 2007. The price of silver in the first quarter averaged $13.31, 37% higher than the same period a year ago, and gold, lead and zinc also increased 17%, 45%, and 54%, respectively, during the same period. If these metals stay on this path and remain strong, as we expect they will, our cash and income generating levels could be even higher than last year. Hecla's low-risk, low-cost silver profile is where the majority of the value of the company lies. And even though our costs for gold production at our La Camorra Unit have risen from a year ago, our cash margin remains healthy because of the increase in the gold price." As a result of performance during the first quarter, Hecla is revising its guidance on estimates for the annual average cash cost per ounce of silver to less than $0.50 per ounce (earlier guidance gave an estimate of less than $1 per ounce), and maintaining its estimate for 2007 of an average gold cash cost of up to $440 per ounce. OPERATIONS AND EXPLORATION Lucky Friday -- The Lucky Friday silver mine in northern Idaho produced 852,113 ounces of silver during the first quarter, at an average total cash cost of $1.77 per ounce. Costs are dramatically lower than the average total cash cost during the first quarter of 2006 of $5.31 per ounce of silver, as a result of approximately 75% of all production now coming from the new 5900 level of this deep underground mine, as well as increased by-product metals prices. The mine is on track to produce more than 3 million ounces in 2007. The average grade of silver was about 11 ounces per ton, approximately the same as a year ago, but lower than the life-of-mine reserve grade as a result of mining longer strike lengths and wider faces to take advantage of the high base metals prices. Ore was mined at greater widths to include stringers that give access to zinc that otherwise would not be mined. This results in an economic benefit but temporarily lowers the silver grade, as anticipated. A 34% increase in silver resource at the Lucky Friday mine in 2006, to 117 million ounces, led to a positive scoping study to increase Lucky Friday's tonnage and production. Basic engineering on an internal shaft is beginning in the second quarter, with construction anticipated to start in 2008. A pre-feasibility study is underway to determine how the company can increase annual production, extend the mine life and increase the minable resource. Completion of the pre-feasibility study is expected next year. Assuming a positive outcome, work would subsequently begin on a feasibility study that could result in sinking an additional surface shaft and constructing a new mill. Meanwhile, underground exploration activities at Lucky Friday continue to produce positive results. Baker said, "The Lucky Friday mine has an unexplored gap of 2,500 feet along the structural trend above the current mining area, and below the historic mining near the surface. During the first quarter, we drilled one long hole up into that gap from the 4050 level of the mine. The material this hole intercepted is very significant and encouraging because it intersected at least six vein zones, which showed low to intermediate grades of silver, lead and zinc. It is very difficult to drill upward, and for safety reasons the hole was stopped while still encountering mineralization. The fact the mineralization is there is good news and lends encouragement to our theory that the veins we are mining in the Lucky Friday expansion area continue strongly in structures above, as well as below, our current workings. Our exploration below the current workings also continues to be successful, and I fully expect to increase our resource this year at depth as far as 7,200 feet below the surface, which is another 400 feet deeper than our currently identified resource. In addition, deeper drilling indicates the mineralization extends even further." Greens Creek -- The Greens Creek silver/zinc/lead/gold mine in Alaska is a joint venture with Rio Tinto. Hecla holds an approximate 30% interest in this extremely low-cost mine. Greens Creek produced 704,928 ounces of silver for Hecla's account during the first quarter, at a negative total average cash cost of $4.62 per ounce. Silver production was nearly 15% higher than the first quarter of 2006, along with slightly increased production of zinc and gold. The mine is expected to contribute about 2.8 million ounces of silver production to Hecla in 2007. Hecla is not the only one benefiting from high metals prices: smelter treatment charges at Greens Creek were about 16% higher than a year ago due to price participation clauses in the smelter contracts. In addition, some revenue from the mine, expected during the first quarter, was delayed into the second quarter due to a weather-related delay in shipping. At Greens Creek, an aggressive underground exploration drill program, utilizing three drills, is focused on expanding the high-grade 5250 zone to the north. The 5250 zone is at a higher elevation in the mine, but adjacent to underground workings. Late this year, these drills will move to the still-expanding West Gallagher zone, and to the NNW and East Ore zones to better define those existing resources. Preparations for an extensive surface exploration and drilling program for this summer is underway and will include the drilling of Little Sore, Upper and West Gallagher. La Camorra -- The La Camorra Unit in Venezuela produced 31,479 ounces of gold at an average total cash cost of $475 per ounce, on track for estimated production of 120,000 ounces of gold this year. Increased costs at La Camorra compared to costs in the first quarter of 2006 of $357 per ounce of gold are due primarily to fewer ounces of gold mined. The decreased production, caused by a lower average gold grade of 0.591 ounce of gold per ton compared to 0.701 ounce of gold per ton during the first quarter of last year, led to higher costs per ounce. Costs are expected to decrease later in the year, as gold production transitions away from the older La Camorra deposit to the new Mina Isidora deposit. Hecla continues to contribute to the improvement of the standard of living for the local, rural communities in the mine vicinity and has an ongoing program to foster good relationships with the various government ministries in Venezuela. San Sebastian and Mexico -- Hecla holds more than 340 square miles of contiguous concessions, called San Sebastian, in the state of Durango in central Mexico. Several promising precious metal targets will be drilled during the 2007 exploration season. During past exploration, more than 15 targets have been generated on the property for the long-term exploration effort on this extremely prospective property located in the middle of Mexico's prolific silver belt. Drilling continues on the St. Jude vein, where mineralized quartz veins have been defined and show some down-plunge continuity. This potential new resource is parallel to and within a kilometer of the Hugh zone, where a pre-feasibility study is being completed. Geophysical anomalies have recently been defined along trend of the past-producing Francine veins at the Nazareno and San Angel areas. Elsewhere on the property, drilling has identified isolated veins and shears in a newly identified, extensive area referred to as the Silver Anomaly, which lies southwest of the Hugh zone. Large and extensive soil sampling has also been completed southwest of the Francine vein in another new, promising area. Drilling has just begun on the large regional quartz veins at the Rio Grande property, located approximately 30 miles south of the San Sebastian property. Rio Grande consists of a series of high-grade veins and breccias that extend for over nine miles. Surface sampling of the veins has confirmed high-grade silver and gold, so we are now preparing for an extensive drill program in 2007. ENVIRONMENTAL In April, Hecla received notice from the US Bureau of Land Management (BLM) that a Hecla subsidiary, Rosebud Mining Company, LLC, had completed all the required reclamation for the Rosebud gold mine in Nevada, which Hecla had operated for four years, until the end of 2000. The BLM gave "sincere thanks to (Hecla employees) Ms. Cindy Moore and Mr. Rich Appling...for the excellent work they have done and the consistent cooperation that we have received during the life of this project. We look forward to working with The Rosebud Mining Company LLC in the future on any mineral actions that it decides to pursue on the public land that we manage." Hecla's Baker said, "This is a small example of the large commitment that Hecla and its people have given to good stewardship and environmental excellence at all our properties. We intend to continue to demonstrate through our current and future operations that quality mining operations and proper care for the environment go hand in hand." HOLLISTER SALE COMPLETED On February 21, 2007, Hecla announced it had entered into an agreement to sell its subsidiary, Hecla Ventures Corp., which holds Hecla's interest in the Hollister Development Block gold exploration project in Nevada, to its former partner in the project, a subsidiary of Great Basin Gold, Inc. On April 19, Hecla announced the completion of the transaction for $45 million in cash and 7,930,214 shares of Great Basin Gold with a market value at the time of closing of $18.6 million. Hecla had spent approximately $30 million over the past two years (most of which had been previously expensed) developing the project toward the earn-in requirement. The company anticipates booking a gain on the sale in the second quarter of 2007 of approximately $63 million. OPPORTUNITIES With the proceeds of the Hollister sale, Hecla has a significant amount of cash and short-term investments and remains debt free. Baker said, "Our cash on hand and our ability to generate significantly more cash through our operations this year puts us in an excellent position to fully fund our aggressive exploration program and any capital development planned for current operations. In addition, we are considering property submissions we receive and acquisition opportunities." Baker concluded, "Hecla's share price has outperformed that of our silver peers, the silver exchange traded fund and the gold indices over the past three months. We take that as a signal that the market has recognized our undervalued position and is just now starting to realize our future potential cash and income generating abilities. Our upside continues with our expectation of adding additional resources through our focused exploration program, where we plan to spend upwards of $22 million this year. And our robust financial position will enable us to take advantage of the right acquisition or partnership opportunity when it arises."

Management also uses this measurement for the comparative monitoring of performance of mining operations period-to- period from a cash flow perspective. "Total cash cost per ounce" is a measure developed by gold companies in an effort to provide a comparable standard; however, there can be no assurance that our reporting of this non-GAAP measure is similar to that reported by other mining companies. Cost of sales and other direct production costs and depreciation, depletion and amortization are the most comparable financial measures calculated in accordance with GAAP to total cash costs. (2) Costs per ounce of gold are based on the gold produced by the La Camorra mine and our Block B concessions only. During the quarters ended March 31, 2007 and 2006, gold produced from third-party mining operations located near the La Camorra mine and Block B concessions was treated as a by-product credit and included in the calculation of gold costs per ounce. (3) Incentives have been offered at the La Camorra mine for voluntary reduction of the workforce. During the quarter ended March 31, 2007, these costs of sales and other direct production costs of $0.3 million were not included in the determination of total cash costs for gold operations.
