Insights
The reported exploration results from Hecla Mining Company indicating the second highest silver reserves and the largest gold resource in the company's history are significant indicators of the company's potential growth and sustainability. The discovery of high-grade and wide intercepts, particularly the 54 ounces per ton silver over 39 feet, suggests an increase in the intrinsic value of the company's mining assets. This could lead to a positive reassessment of the company's stock by investors and analysts, as reserve expansions often correlate with increased production capacity and potential revenue growth.
Furthermore, the strategic acquisition of ATAC and its extensive land package may provide long-term growth opportunities for Hecla. The company's positioning as a leading silver producer in the U.S. and its expected rise to Canada's largest silver producer by 2024 could be leveraged in the context of the growing demand for silver in the solar industry. This strategic alignment with the renewable energy sector could enhance investor sentiment, especially within the ESG investing community.
Hecla Mining's exploration update and reserves report have vital implications for financial forecasting and valuation. The company's ability to replace 11 million ounces of silver production and the increase in measured and indicated gold reserves by 21% post-acquisition of ATAC Resources Ltd. are important for projecting future cash flows. The unchanged metal price assumptions for silver, with a slight increase for gold, indicate a stable pricing environment that the company is using for its reserve calculations, which is an important factor for investors to consider when evaluating the company's future profitability.
However, the 16% decrease in gold reserves due to the transition at Casa Berardi to a surface operation only is a noteworthy development. It reflects a strategic shift that could impact the cost structure and operational efficiency of the company. Investors should closely monitor how these changes affect the company's margins and overall financial health.
The technical aspects of Hecla's exploration results, such as the reported high-grade mineralization at depths greater than 1,000 feet and the expansion of mineralization at Greens Creek, indicate a robust exploration methodology and potential for resource longevity. The reported grades and widths from Keno Hill and Greens Creek are substantial and the use of terms like 'proven and probable reserves' and 'measured and indicated resources' are industry standards for reporting mineral assets, reflecting the level of confidence in the economic extraction of these minerals.
It is also important to note the company's strategic focus on district-sized properties, which typically offer economies of scale and can lead to lower production costs per ounce of metal. This strategy, combined with the company's significant landholdings in politically stable regions such as the U.S. and Canada, can be seen as a risk mitigation factor that might appeal to risk-averse investors.

EXPLORATION AND PRE-DEVELOPMENT UPDATE
Keno Hill,
At Keno Hill, the underground definition and surface exploration drilling programs continued to be focused on extending mineralization, resource conversion in the high-grade Bermingham Bear Zone Veins (Bear, Footwall, and Main Vein Zones), and discovering and defining new mineral resources. During the fourth quarter, two underground drills completed over 12,800 feet of definition and geotechnical drilling, and two surface core drills completed over 14,400 feet of exploration drilling targeting the Deep Bermingham, Bermingham Townsite, Inca, and Coral Wigwam target areas (Figure 1).
Bermingham underground definition and exploration drilling in the three Bear Zone veins (Bear, Footwall, Main veins) continues to extend mineralization to the northeast, southeast, and down dip outside of the current reserve shapes (Figures 2, 3 and 4). Drilling in the Bear Vein identified strong vein mineralization between the Ursa and Splay faults where testing at higher elevations had no significant mineralization; this new drilling expands higher-grade mineralization between the faults and to the southwest near the Arctic fault zone. Drilling in the Footwall Vein intersected substantially wider and higher-grade mineralization than modeled to the southwest internal to the reserve shape. Drilling in the Main Vein intercepted strong mineralization at depth and along strike significantly increasing the strike and depth of high grade in this zone. Assay highlights include (reported widths are estimates of true width):
-
Bear Vein: 21.4 oz/ton silver,
2.8% lead, and0.5% zinc over 11.7 feet-
Includes: 129.9 oz/ton silver,

Initial surface exploration drilling tested for continuity of the Bermingham vein system at depth intersected strong mineralization (87.2 oz/ton silver over 0.6 feet) 1,050 feet below the existing Deep Bermingham resource. This mineralized intercept resets and expands exploration potential in the district where previously high-grade silver mineralization was thought to occur only in the upper parts of the favorable Basil Quartzite host stratigraphy.
Surface exploration drilling continued targeting the Bermingham Townsite Vein and Townsite Vein Splay system intersected strong mineralization which continues to be open for expansion at depth. Assay highlights include (reported widths are estimates of true width):
-
Townsite Vein Splay: 73.5 oz/ton silver,
1.4% lead, and0.2% zinc over 4.6 feet
Surface exploration drilling targeting the Inca Vein located east of the Hector Calumet area testing for continuity from historic drillhole intercepts intersected strong silver mineralization with significant intercepts associated indium and zinc mineralization. Limited drilling to date has outlined a mineralized zone of over 800 feet of strike length and is open for expansion to the northeast and southwest along strike and up and down dip.

Greens Creek,
At Greens Creek, four underground drills completed over 38,000 feet of drilling in 79 drillholes focused on resource conversion and exploration that extends mineralization of known resources. Drilling was focused in the 9a, 200 South, East, West, Gallagher, and Gallagher Fault Block zones while assay results were received from drilling in the 200 South, 5250, East, Upper Plate, West, and 9a zones (Figure 5).
Underground drilling completed 25 drillholes in the 200 South Zone targeting the upper orebody and the deeper mine contact portions of the zone covering a strike length of 1,050 feet. Unexpected zones of mineralized ore lithologies were intersected early in a few of the drillholes before the targeted contact expanding mineralization in those areas. Highlights from this drilling include:
-
17.4 oz/ton silver, 0.02 oz/ton gold,
4.1% zinc, and3.0% lead over 21.1 feet -
11.4 oz/ton silver, 0.06 oz/ton gold,
3.1% zinc, and1.5% lead over 7.0 feet
Drilling in the 5250 Zone targeted 150 feet of strike length in the upper portion of the resources intersected thick sequences of white baritic and massive sulfide ore lithologies above the modeled resources expanding mineralization in that area of the zone. Highlights from this drilling include:
-
18.7 oz/ton silver, 0.05 oz/ton gold,
11.4% zinc, and3.6% lead over 26.8 feet
Additional assay results have been received from underground drilling in the northern, central, and eastern portion of the Upper Plate zone, targeting mineralization for upgrading and expanding resources over 900 feet of strike length. Results to date indicate that drilling is upgrading and expanding mineralization in the Upper Plate Zone. Highlights from this drilling include:
-
19.6 oz/ton silver, 0.05 oz/ton gold,
10.9% zinc and5.4% lead over 27.9 feet -
28.3 oz/ton silver, 0.01 oz/ton gold,
2.6% zinc and1.3% lead over 23.9 feet
Strong assay results received from underground drilling in the West Zone extend mineralization at the lower mine contact over 400 feet to the west of previous intercepts and infills a 200-foot gap in drilling in the central ore band (Figure 6). Highlights from this drilling include:
-
63.4 oz/ton silver, 0.64 oz/ton gold,
8.3% zinc, and4.3% lead over 26.04 feet -
28.3 oz/ton silver, 0.08 oz/ton gold,
8.3% zinc, and4.7% lead over 12.8 feet -
35.2 oz/ton silver, 0.08 oz/ton gold,
10.0% zinc, and6.3% lead over 27.3 feet

Cautionary Statements to Investors on Reserves and Resources
This news release uses the terms “mineral resources”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”. Mineral resources that are not mineral reserves do not have demonstrated economic viability. You should not assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. Further, inferred mineral resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically, and 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. We report reserves and resources under the SEC’s mining disclosure rules (“S-K 1300”) and Canada’s National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) because we are a “reporting issuer” under Canadian securities laws.

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. |

| Note: All estimates are in-situ except for the proven reserves at Greens Creek which are in surface stockpiles. Mineral resources are exclusive of reserves. | ||
(8) |
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 level of confidence than the level of confidence of 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. |
