Insights
The latest exploration results from Hecla Mining demonstrate exceptional operational execution and strategic foresight in resource management. The achievement of 240 million ounces in silver reserves, while actively mining 18.7 million ounces in 2024, showcases the company's ability to sustainably replace resources - a important factor for mining company valuations.
The 17% increase in Keno Hill's reserves to 64 million ounces is particularly significant as it indicates successful conversion of resources to reserves, validating the initial acquisition strategy. The high-grade intercepts reported, including 42.8 oz/ton silver over 6.8 feet at the Main Vein, suggest potential for lower extraction costs and higher margins.
The conservative pricing assumptions (
The exploration success at Greens Creek, particularly the intercept of 24.3 oz/ton silver over 46.6 feet in the 5250 Zone, represents exceptional width and grade that could significantly impact future production profiles. The consistent high-grade results across multiple zones suggest potential for sustained high-grade feed to the mill, which typically correlates with lower per-ounce production costs.
The technical achievements in resource replacement and expansion, coupled with the discovery of new high-grade zones, position Hecla for sustained operational performance. The extensive drilling program has not only replaced production but also identified new targets for future development, providing a robust pipeline for resource growth.

"Hecla's silver reserves stand at 240 million ounces, the second-highest level in our 134-year history and only 1 million ounces below our peak in 2022," said Rob Krcmarov, President and CEO. "Our 2024 exploration program continued to deliver exceptional results at both Keno Hill and Greens Creek while Keno Hill reserves grew by over
Kurt Allen, Vice President of Exploration, commented on the exploration success: "The 2024 drilling program has significantly advanced our understanding of the high-grade mineralization controls at both Keno Hill and Greens Creek. At Keno Hill, the Bermingham Footwall and Main Vein zones continue to deliver exceptional silver grades over mineable widths and remain open for expansion. The emerging cluster of high-grade silver values beneath the Bermingham Deep Northeast Ore Zone is particularly exciting, suggesting proximity to a new ore-shoot that will be a key focus of our 2025 drilling program. At Greens Creek, the strong results from the West Zone and 5250 Zone support our view that this world-class deposit continues to hold significant exploration potential."

EXPLORATION UPDATE
Keno Hill,
Fourth quarter drilling at Keno Hill substantially expanded high-grade mineralization through an aggressive dual-focus program of underground definition and surface exploration drilling. Underground drilling completed 7,100 feet, concentrating on resource conversion and expansion of the high-grade Bermingham Bear Zone Veins. Concurrent surface exploration deployed five core drills to complete 28,000 feet across multiple promising targets including the Bermingham Deep, Elsa 17-Dixie, Inca, and Hector-
Definition drilling in the Bear Zone veins yielded significant results, particularly in the Footwall and Main Veins where high-grade mineralization was extended both at depth and along strike. While drilling in the Bear Vein identified narrow vein mineralization between the Ursa and Arctic faults, the most substantial gains came from the Footwall and Main Veins, where strong high-grade intercepts significantly expanded the known mineralized zones. Both the Footwall and Main Vein zones remain open at depth, with further drilling planned for the first half of 2025 to test their expansion potential. Assay highlights include (reported widths are estimates of true width):
-
Bear Vein: 13.2 oz/ton silver,
2.6% lead, and0.9% zinc over 7.5 feet -
Bear Vein: 12.6 oz/ton silver,

Surface exploration drilling delivered exciting results from both the Bermingham system and Inca Vein target areas.
At Bermingham, drilling intercepted significant mineralization across multiple veins, highlighted by an 11.3-foot intersection in the Footwall Vein grading 11.1 oz/ton silver with associated base metals. This intercept, located beneath the northeastern edge of the Bermingham Deep Northeast Ore Zone, suggests proximity to a new ore-shoot controlled by an interpreted vein intersection. The area is slated for follow-up drilling in 2025.
At the Inca Vein target, initial drilling has outlined over 800 feet of mineralized strike length, delivering exceptional results including 22.3 feet grading 18.1 oz/ton silver,
Greens Creek,
At Greens Creek, two underground drilling rigs completed 27 drillholes, totaling 17,083 feet. Definition drilling was focused on resource conversion and exploration and resulted in extending mineralization from known resources. Underground definition drilling targeted the 9A, East, and Gallagher zones and exploration targeted the Gallagher Zone (Figure 5). Assay results were received during the quarter from the 5250, 9A, Gallagher, West, 200S, and UPP zones.
Underground definition drilling delivered mixed but overall positive results across multiple zones. At the Gallagher Zone, four drillholes across two sections encountered elevated alteration, with

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. |

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. |
