Key Terms

measured and indicated technical
Measured and indicated are two levels of confidence used to describe the size and quality of a mineral deposit: "measured" means the quantities and grade are well tested and closely known, while "indicated" means they are reasonably estimated but with more uncertainty. Investors use these categories to judge how reliably a resource can be converted into reserves and future cash flow—think of measured like a weighed recipe and indicated like a good estimate based on past batches.
inferred resources technical
An inferred resource is an early-stage estimate of how much mineral or fuel may be present in the ground based on limited geological evidence and sampling. Think of it like seeing scattered clues that suggest a buried treasure might exist but not having dug enough to be sure; the potential size and value are uncertain. For investors it signals possible upside but carries high risk and should not be treated as proven supply or relied on for firm production plans.
proven and probable technical
Proven and probable is a paired classification used for natural resource reserves that signals how confident geologists and engineers are that a deposit can be economically mined. “Proven” describes material known with high certainty to be recoverable, while “probable” covers material that is reasonably likely but less certain; together they help investors judge the size, risk and value of a mining project, like knowing what’s definitely in your pantry versus what you expect to find.
cutoff grades technical
Cutoff grades are the minimum concentration of a metal or mineral in rock that a mining operation considers worth extracting and processing. Think of it like sorting fruit: only pieces above a certain ripeness are kept because hauling and processing lower-quality items would cost more than they’re worth. For investors, cutoff grades directly affect how much of a deposit is counted as economically recoverable, which in turn influences project value, production forecasts and cost estimates.

Silver Industry Peer Leading Reserve Mine Life Maintained

COEUR D'ALENE, Idaho--(BUSINESS WIRE)-- Hecla Mining Company (NYSE:HL) ("Hecla", "we", "our" or the "Company") today reported year-end mineral reserves and resources and exploration results. In 2026, the Company plans to invest nearly double the 2025 investment in exploration and pre-development, focused on Nevada, Greens Creek, Keno Hill and Lucky Friday, with the goal of replacing or exceeding annual reserve depletion.

Reserves and resources herein include those of Hecla Quebec Inc. ("HQI"), including Casa Berardi, which is subject to a pending sale to Orezone Gold Corporation announced January 26, 2026. See "Casa Berardi Transaction" below for details.

EXPLORATION AND RESERVES & RESOURCES HIGHLIGHTS

 

Year-End 2025 Position:

  • Silver reserves of 231 million ounces after producing 17 million ounces in 2025, maintaining silver peer leading average reserve life, nearly double the industry average
  • Measured and Indicated silver resources of 161 million ounces; Inferred silver resources of 468 million ounces
  • Proven and Probable gold reserves of 2.0 million ounces
  • Measured and Indicated gold resources of 4.5 million ounces; Inferred gold resources of 6.3 million ounces
  • Demonstrated robust economics using conservative pricing ($25/oz silver and $2,100/oz gold for reserves; and $26/oz silver and $2,250/oz gold for resources). High-grades and sharp ore boundaries limit reserve sensitivity to metal price assumptions, while preserving margin potential across metals cycles

2025 Asset Highlights:

  • Greens Creek produced 8.7 million ounces of silver in 2025 while growing the reserve base by 2.4 million ounces. In the East Zone, one drillhole intersected 247.3 oz/ton silver, 1.94 oz/ton gold, 22.7% zinc and 12.1% lead over 7.7 feet.
  • Lucky Friday produced a record 5.3 million ounces of silver in 2025 and replaced 5.0 million in the reserve. Mineralization remains open in multiple directions at depth at this long-life asset, providing potential for further reserve replacement and expansion.
  • Mining experience at Keno Hill has led to refined modeling metrics which should improve technical accuracy and data interpretation. A new ore shoot discovered in 2025 is one of many exploration targets for the 2026 drill program. Drilling at Keno Hill continues to upgrade and expand resources, with the Bermingham Vein returning 36.4 oz/ton silver, 3.4% zinc, and 3.4% lead over 21.4 feet, extending mineralization 140 feet beyond the previous resource boundary.
  • Follow up drilling at Midas in Nevada yielded a second high-grade intercept grading 0.46 oz/ton gold and 0.9 oz/ton silver over 6.1 feet, including 1.31 oz/ton gold and 2.4 oz/ton silver over 2.0 feet, located 720 feet SE of the initial discovery.
  • Cutoff grades raised across the asset base to factor in cost inflation, consistent with the approach of prior years.

A breakdown of the Company’s reserves and resources along with metal price assumptions are set out in Tables A and B at the end of this news release.

“Our 231 million ounces of reserves at year-end 2025 reflects refined technical standards we've implemented across our reserve modeling as we’ve learned from mining these deposits, strengthening the quality and credibility of our estimates,” said Rob Krcmarov, President and CEO. “Looking ahead, we're signaling our confidence in future reserve replacement by nearly doubling our exploration budget in 2026 compared to the prior year. This elevated investment at our core assets positions us to more than replace reserves on a go-forward basis and sustain the industry’s best average reserve mine life.”

Kurt Allen, VP Exploration, added: “Our 2025 programs delivered exceptional results that validate our balanced strategy of pursuing high-impact discoveries while systematically expanding reserves at producing assets. At Greens Creek and Keno Hill, definition drilling successfully converted Inferred resources and extended resource boundaries. In Nevada, Midas has identified compelling high-grade discovery targets with significant upside. With the increased resources we're deploying in 2026, we're confident in our ability to more than replace reserves annually while advancing transformative discoveries within our district-scale properties.”

EXPLORATION UPDATE

 

Investment and Strategy

During 2025, the Company invested $25.2 million in exploration and corporate development (and $2.5 million in pre-development) activities, focused on high-impact discovery drilling at Midas in Nevada and resource expansion programs at our producing assets. This strategy balances district-scale discovery with near-mine resource definition and reserve extension. Guidance for 2026 calls for $55 million investment in exploration and pre-development.

Producing Asset Resource Definition

Drilling programs at Greens Creek and Keno Hill continue to define and expand mineralization near resource boundaries, converting Inferred resources and identifying additional reserve extension opportunities.

Greens Creek

Definition drilling at Greens Creek continued with three underground drilling rigs primarily focused on the East Zone. Notable East Zone assay results include one drillhole that intersected 247.3 oz/ton silver, 1.94 oz/ton gold, 22.7% zinc and 12.1% lead over 7.7 feet, upgrading the resource. Another drillhole, completed just outside of the resource boundary, intersected 91.2 oz/ton silver, 0.21 oz/ton gold, 9.2% zinc and 4.5% lead over 17.7 feet.

Keno Hill

At Keno Hill one definition drilling rig continued to define and expand the Arctic Zone mineralization at the Bermingham Mine. One intercept into the Footwall Vein returned 179.2 oz/ton silver, 1.5% zinc, 6.1% lead over 14.2 feet, upgrading the resource. Another intercept into the Bermingham Vein returned 36.4 oz/ton silver, 3.4% zinc and 3.4% lead over 21.4 feet expanding the resource 140 feet from the previous boundary.

EXPLORATION PROGRAMS

Greens Creek

Surface exploration assay results received from drilling at the Gallagher Fault Block, West Gallagher, and East Ore Offset targets. Notable assay results from the West Gallagher Zone drilling include 1.0 oz/ton silver, 1.09 oz/ton gold, 0.8% zinc, and 0.1% lead over 1.1 feet. Follow up offset drilling of this high-grade gold intercept is being evaluated.

In January the U.S Forest Service approved the five-year plan of operations for the Company’s Greens Creek Surface Exploration Project. The FONSI and Decision Notice authorizes testing of existing mineralized targets and identification of new targets not accessible from underground operations. Inclusion of this project on the FAST-41 Transparency List acknowledges the strategic importance of identifying domestic sources of critical minerals and responsibly producing them.

Nevada Exploration

Follow-up exploration drilling of the high-grade intercept at the Sinter Offset Vein area (previously reported in November 2025) returned a second high-grade intercept, located 720 feet SE of initial intercept, at similar elevation. Drillhole DMC-475 returned 0.46 oz/ton gold and 0.9 oz/ton silver over 6.1 feet, including 1.31 oz/ton gold and 2.4 oz/ton silver over 2.0 feet, from a 2.0-foot, well-developed, multiphase quartz breccia within a 6.1-foot structure. Follow-up offset drilling is in progress, and this mineralization is open for expansion in all directions.

Detailed definition drill assay highlights can be found in Table C at the end of this release.

The term “reserve” means an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. The term “proven reserves” means the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource. See footnotes 8 and 9 below.

(2)

 

Mineral reserves are based on $25.00/oz silver, $2,100/oz gold, $0.90/lb lead, $1.15/lb zinc, unless otherwise stated. All Mineral Reserves are reported in-situ with estimates of mining dilution and mining loss.

(3)

 

The reserve NSR cut-off values for Greens Creek are $275/ton for all zones; metallurgical recoveries (actual 2025): 79.3% for silver, 74% for gold, 82.6% for lead, and 88.8% for zinc.

(4)

 

The reserve NSR cut-off values for Lucky Friday are $280/ton for all veins; metallurgical recoveries (actual 2025): 94.5% for silver, 94.3% for lead, and 85.1% for zinc.

(5)

 

The average reserve cut-off grades at Casa Berardi are 0.11 oz/ton gold (3.8 g/tonne) underground and 0.03 oz/ton gold (0.97 g/tonne) for open pit. Metallurgical recovery (actual 2025): 87% for gold; US$/CAN$ exchange rate: 1:1.35.

(6)

 

The reserve NSR cut-off value at Keno Hill is $336/ton (CAN$500/tonne), Metallurgical recovery (actual 2025): 96.2% for silver, 94% for lead, 81% for zinc; US$/CAN$ exchange rate: 1:1.35.

(7)

 

The term “probable reserves” means the economically mineable part of an indicated and, in some cases, a measured mineral resource. See footnotes 9 and 10 below.

The following table summarizes the in-situ mineral resources (8) for all properties, exclusive of mineral reserves, as of December 31, 2025:

The term "mineral resources" means a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.

(9)

 

The term "measured resources" means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

(10)

 

The term "indicated resources" means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower confidence level than a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve.

(11)

 

The term "inferred resources" means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project and may not be converted to a mineral reserve.

(12)
