COEUR D'ALENE, Idaho--(BUSINESS WIRE)--Hecla Mining Company (NYSE:HL) today reported the second highest silver reserves in its 130-year history and provided an update on its exploration programs during the fourth quarter of 2021 and plans for 2022.
RESERVES & RESOURCES HIGHLIGHTS
- Silver reserves increased to 200 million ounces with Greens Creek increasing 12%.
- Gold production was replaced, and reserves increased by 14%.
- Measured and indicated resources declined primarily due to conversion to reserves.
- Inferred resources increased 8% for silver and 2% for gold.
- Extended or maintained already long reserve mine lives.
FOURTH QUARTER EXPLORATION HIGHLIGHTS
- Greens Creek drilling upgraded and expanded resources in 4 of the 9 zones.
- Drilling from Casa Berardi’s 9 rigs converted and expanded resources and discovered new mineralized structures.
- Midas exploration defined and expanded mineralization on the Sinter Structure and intersected high-grade mineralization on two new structures that are open along the East Graben Corridor.
- Hollister drilling from the new decline confirmed multiple new veins zones at the Hatter Graben resource.
- San Sebastian’s El Bronco and El Tigre veins reported initial inferred resources.
- 2022 exploration and pre-development planned spend of $45 million.
“Hecla’s silver reserves are near our all time high with Greens Creek reaching 125 million ounces, that mine’s second highest since 2002, and Lucky Friday’s 75 million ounces giving it a reserve mine life in excess of 15 years,” said Phillips S. Baker, Jr., President and CEO. “Since 2008, Hecla has, through exploration, added 239 million silver ounces in reserves, replacing production while also growing resources. We see further growth in reserves, resources, and production from our exciting exploration program. With the increasing need for silver to contribute to the transition to cleaner energy, Hecla has both the largest silver reserve and production in the United States which positions us to meet demand long into the future.”
YEAR-END 2021 RESERVES AND RESOURCES
2021 proven and probable silver reserves were the second highest in Hecla’s history at 200 million ounces. The Company not only replaced silver production (15.2 million silver ounces contained), but also increased proven and probable reserves by 6%, or 11.5 million ounces over 2020. Gold production was also replaced (244,680 gold ounces contained) and proven and probable reserves increased 14% to 2.7 million ounces. Zinc production of 71,000 tons was replaced and reserves increased 2% to a total of 907,000 tons. Lead production of 49,000 tons was nearly replaced with a slight decrease of 1% to 735,000 tons. Reserve price assumptions for 2021 were $17.0/oz silver, $1,600/oz gold, $1.15/lb. zinc, and $0.90/lb. lead.
Measured and indicated silver ounces decreased 9% to 207 million ounces, from its record level in 2020, due to conversion to reserves at Greens Creek and Lucky Friday. Measured and indicated gold ounces decreased 6% to 3.5 million ounces due to conversion to reserves at Casa Berardi and Greens Creek.
Inferred silver resources increased 8% to 491 million ounces while inferred gold resources increased 2% to 5.6 million ounces due to increases at Greens Creek, Lucky Friday, San Sebastian in Mexico, and Midas in Nevada.
Greens Creek
At Greens Creek, 2021 production across all four metals was replaced and silver, gold, zinc, and lead reserves increased by 12%, 14%, 11%, and 11%, respectively, over 2020 reserves.
Measured and indicated silver resources at year-end 2021 were 107 million ounces, a 7% decrease over 2020 due to conversion to reserves. Inferred silver resources increased 18% given renewed exploration drilling and increased metal prices to a total of 27.5 million ounces.
Casa Berardi
At Casa Berardi, 2021 mining depletion was replaced and gold reserves increased 16%, or an addition of 242,000 ounces over 2020 to 1.8 million ounces. The increase is mostly due to additions at the 160 Open Pit.
Measured and indicated gold resources decreased 16% overall from 2020 (-89% open pit and -4% underground) to 1.1 million ounces due to conversion to reserves and higher cut-off grades given increased mining costs. Reserve conversions were mostly seen in the 160 Open Pit zones. Inferred gold resources declined 17% from 2020 given conversion to higher resource classes and reserves.
Lucky Friday
At the Lucky Friday, proven and probable reserves are currently 75 million ounces of silver (3% lower from 2020), 452,440 tons of lead and 181,020 tons of zinc.
Measured and indicated silver resources decreased 8% to 80 million ounces over 2020; lead and zinc measured and indicated resources decreased 6% and 4%, respectively. Decrease in measured and indicated resources is due to conversion to reserves.
Inferred resources significantly increased year-over-year and include 42 million ounces of silver (+65%), 311,850 tons of lead (+62%) and 129,600 tons of zinc (+55%). Increase in inferred resources is mostly due to additions in the upper portions of the 30 Vein adjacent to reserve blocks; drilling plans are in place to better define these resources in order to convert them to reserve.
A breakdown of the Company’s reserves and resources is set out in Table A at the end of this news release.
EXPLORATION AND PRE-DEVELOPMENT UPDATE
Exploration and pre-development expenses totaled $12.9 million for the fourth quarter and $47.9 million for the full year, which was a record and an increase of $29.6 million compared to 2020.
Exploration Update for Fourth Quarter, 2021
At Casa Berardi, six underground and three surface core drills focused on resource conversion and exploration drilling to upgrade and expand resources in the West, Principal, and East mine areas. Drilling in the West Mine targeted the eastern edge of the 113 Zone to define continuity and expand mineralization to the east. Highlights from this drilling include intercepts grading 0.46 oz/ton gold over 12.5 feet and 0.39 oz/ton gold over 13.1 feet.
Drilling in the Principal Mine targeted the upper part of the 123 Zone and the western part of the 124 Zone and successfully extended and confirmed the continuity of both zones. Highlights from this drilling include intercepts grading 0.69 oz/ton gold over 11.2 feet and 0.52 oz/ton gold over 9.2 feet. Drilling in the 124 Zone targeted mineralized lenses at the contact between a volcanic and sedimentary unit south of the Casa Berardi Fault. Results from this drilling confirms the presence of the mineralized structure west of the current 124-22 lens with intercepts including 0.21 oz/ton gold over 27.9 feet and 0.13 oz/ton over 11.2 feet.
Drilling in the East Mine targeted upgrading and expanding mineralization in the 146 and 148 zones. Many assay results are pending; results received to date from the 146 Zone drilling consists of wide zones of low-grade gold mineralization with narrow internal high-grade intervals. Similarly, drilling in the 148 Zone expanded mineralization to the south of the Casa Berardi fault zone with intercepts including 0.13 oz/ton gold over 26.2 feet with narrow internal higher-grade intervals.
Detailed 3D geologic modeling and target definition has been completed for the West, Principal, and East mine areas.
At Greens Creek, two underground core drills focused on resource conversion in the 9A and 200 South zones and exploration in the 200 South and Gallagher Fault Block zones. Highlights from the 9A drilling include intercepts containing 29.2 oz/ton silver, 0.39 oz/ton gold, 19.0% zinc, and 10.6% lead over 8.0 feet and 19.2 oz/ton silver, 0.14 oz/ton gold, 10.5% zinc, and 6.4% lead over 14.0 feet. Drilling in the 200 South Zone targeted expanding and upgrading resources in the central and southern portions of the zone. While numerous assay results are pending, highlights include intercepts containing 60.0 oz/ton silver, 0.02 oz/ton gold, 8.6% zinc and 4.1% lead over 4.6 feet and 25.7 oz/ton silver, 0.23 oz/ton gold, 2.0% zinc, and 1.0% lead over 6.0 feet.
Drilling at Midas intersected narrow, high-grade gold and silver mineralization along the Sinter Structure, and identified two new mineralized structures, the Racer and Hanging Wall (HW1) Structures. Recent drillhole intersections in the Sinter Structure include 0.25 oz/ton gold and 63.9 oz/ton silver over 0.9 feet estimated true thickness. Mineralization is hosted in quartz carbonate veining which is locally fractured and crushed due to post-mineral fault movement. Sinter mineralization has been intersected over 3,200 feet of strike length and continues to be open for expansion both along strike and dip.
Our first drillhole testing the Racer Structure returned significant assay results of 0.84 oz/t gold and 0.6 oz/t silver over 1.9 feet estimated true thickness. This structure is characterized by intense argillization and brecciation with localized calcite and quartz veinlets. Mineralization remains open along strike and up and down dip.
HW1, a new low angle hanging wall structure has also been identified through geologic interpretation between the Racer and Sinter Structures. Intercepts to date on the HW1 structure include 1.22 oz/ton gold and 0.7 oz/ton silver over 0.8 feet estimated true thickness and 0.03 oz/ton gold and 9.4 oz/ton silver over 2.6 feet estimated true thickness. The orientation and grade distribution along the structure is currently being investigated.
At Hollister, the development drift advanced at the Hatter Graben exploration area allowing completion of the first drillhole that targeted and confirmed multiple zones of banded quartz veins and veinlets south of the existing resource. Intercepts from this initial drillhole include 1.27 oz/ton gold and 1.1 oz/ton silver over 0.9 feet estimated true thickness and 0.23 oz/ton gold and 7.7 oz/ton silver over 1.0 foot estimated true thickness.
Exploration at San Sebastian included deeper drill testing in both the El Bronco and El Toro vein systems in addition to drill testing of four Short Vertical Reverse Circulation (SVRC) anomalies and geologic studies. Assay results from the deeper drilling confirm vein continuity at depth at both El Bronco and El Tigre and intersected a new hanging wall vein at El Tigre.
More complete drill assay highlights can be found in Table B at the end of the release.
Montana Pre-development Update
Hecla has withdrawn the Plan of Operations for Rock Creek and Montanore from consideration by the United States Forest Service (USFS). These plans were prepared by each project’s prior owner and do not have the data necessary for Hecla to formulate a modern mine plan. The Company intends to submit a new Plan of Operations for just the Montanore site that will be limited to geologic and environmental evaluation activities only. If approved and subsequent data collection and analysis activities suggest development of a mine is feasible and economic, then a new Plan of Operations for construction and development at Montanore would be submitted to the USFS. While no activities beyond care and maintenance are currently planned for Rock Creek, mineral and other property rights there will not be impacted.
2022 Exploration Program
More than a quarter of the total expenditures in 2022 are planned for Casa Berardi (16%) and Greens Creek (11%) exploration. Exploration at both Casa Berardi and Greens Creek is focused on replacing production and expansion of high-grade underground reserves and resources through drill testing and conversion of inferred resource to reserves.
At Casa Berardi, underground definition drilling will focus on the following areas: 1) the 118 and 119 zones expanding resources to the west and east of the current reserves, 2) the high-grade plunge at depth and to the east in the Lower 123 Zone in addition to infilling the gap between the Lower 123 and Upper 123 zones, and 3) upgrading resource at depth in the 148 Zone. Exploration drilling will focus on testing the high-grade up and/or down plunge extensions of the 113, 116, 118, 123, 128, 134, 146 and 148 zones as defined from the recent 3D geological modeling and targeting completed in 2021. In addition to these underground exploration programs within the mining lease at Casa Berardi, surface sonic drilling is planned for initial testing of regional target areas in the west, central, and east claim blocks along the Casa Berardi Break. This drilling will enhance historic till sampling in addition to mapping the subsurface bedrock lithologies, alteration, and structures.
At Greens Creek, underground definition drilling will focus on upgrading resources in the West, East, Southwest, Gallagher, and 200 South ore zones while underground exploration drilling will focus on extending mineralization along strike to the south for the 200 South, Gallagher, and Gallagher Fault Block zones in addition to targeting the westward extension of the East Ore Zone above the Klaus Shear and an offset segment of the West Zone. Surface exploration drilling will be focused on advancing the understanding of the geology and discovery of new mineral zones in the Lil’Sore trend and Lil’Sore Prospect target areas and extending mineralization in the near mine 5250 and Upper Plate zones.
Nevada exploration is expected to be 30% of the total planned expenditures, with drilling programs at Hollister, Midas, and Aurora, in addition to detailed mapping, sampling, and target generation at all three projects.
At Hollister, exploration of the Hatter Graben is expected with further development of the decline setting up exploration drilling to upgrade a portion of the current Hatter Graben resource and explore additional Hatter Graben veins both to the south and east of the current resource area. Pre-development spend in 2022 will primarily be focused on advancing the Hatter Graben decline and is estimated at 8% of the total expenditures. To date 2,400 feet of development has been completed along with the necessary ventilation and dewatering infrastructure, additional footage is planned through the first half of 2022.
Exploration at Midas will focus on the two miles of strike length along the Eastern Graben Corridor. Drilling will focus on wide-spaced offsets along the Racer structural corridor near intersections with the northeast oriented Owhyee structures, structural splays off the Racer structure (Vapor Trail), and the northern extension of Little Opal.
At Aurora, drilling is planned to test high-grade vein extensions from historic production areas and the Sawtooth Ridge target area.
San Sebastian represents 8% of the planned exploration spend, focusing on evaluating both near surface and deeper precious metal mineralization. Core drilling is planned to target deeper mineralization in the Middle, North, Francine, El Toro, El Tigre, and El Bronco vein systems. Core drilling will also target deeper high-grade mineralization in the La Roca district which represents a fully preserved epithermal system with strong acid sulfate alteration at the surface. In addition, a Short Vertical Reverse Circulation (SVRC) drilling program north of the San Sebastian Mine area and into the southern portion of the La Roca district will focus on defining new near-surface targets under cover.
Exploration programs are planned to be reinitiated in both the Creede district in Colorado and Republic district in Washington, and combined, accounts for approximately 10% of the total expenditures with field work and surface drilling programs in both districts. At Creede, drilling will focus on surface drilling of the North Bulldog target testing previous narrow high-grade mineralization deeper in the more favorable volcanic sequence which was historically the best host to mineralization. We also plan to initiate underground access and rehabilitation of the main level in the Bulldog mine to eventually provide platforms for underground drilling of the prospective veins.
Analytical turnaround times for assay results from the ISO-certified analytical laboratories were delayed during 2021 due to COVID-19 related staffing issues, increased sample load, and supply chain issues. Currently there are 14,000 samples pending assays with about 80% from Nevada. To support drill targeting, we use ¼ core sample with secondary labs. Final assays will continue to be delayed in 2022.

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. On October 31, 2018, the SEC adopted new mining disclosure rules (“S-K 1300”) that is more closely aligned with current industry and global regulatory practices and standards, including National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) which we comply with because we also are a “reporting issuer” under Canadian securities laws. While S-K 1300 is more closely aligned with NI 43-101 than the prior SEC mining disclosure rules, there are some differences. NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all resource and reserve estimates contained in this press release have been prepared in accordance with NI 43-101, as well as S-K 1300.
Qualified Person (QP) Pursuant to Canadian National Instrument 43-101

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. |
|
(7) 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. Resources are reported in accordance with Section 1300 of Regulation S-K of the Securities Act of 1933, as amended and NI 43-101. |
|
(8) 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, as defined in this section, 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. |
|
(9) 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. |
|
(10) 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. |
|
(11) Mineral resources are based on $1700/oz gold, $21/oz silver, $1.15/lb lead, $1.35/lb zinc and $3.00/lb copper, unless otherwise stated. |
|

|
(14) The average resource cut-off grades at Casa Berardi are 0.089 oz/ton gold (3.06 g/tonne) for underground and 0.036 oz/ton (1.22 g/tonne) for open pit; metallurgical recovery (actual 2021): 84.82% gold; US$/CAN$ exchange rate: 1:1.275. |
|
(15) Indicated resources for most zones at San Sebastian based on $1500/oz gold, $21/oz silver, $1.15/lb lead, $1.35/lb zinc and $3.00/lb copper using a cut-off grade of $90.72/ton ($100/tonne); $1700/oz gold used for Toro, Bronco, and Tigre zones. Metallurgical recoveries based on grade dependent recovery curves: recoveries at the mean resource grade average 89% silver and 84% gold for oxide material and 85% silver, 83% gold, 81% lead, 86% zinc, and 83% for copper for sulfide material. Resources reported at a minimum mining width of 8.2 feet (2.5m) for Middle Vein, North Vein, and East Francine, 6.5ft (1.98m) for El Toro, El Bronco, and El Tigre, and 4.9 feet (1.5 m) for Hugh Zone and Andrea. |
|
(16) Mineral resources for Fire Creek, Hollister and Midas are reported using $1500/oz gold and $21/oz silver prices, unless otherwise noted. A minimum mining width is defined as four feet or the vein true thickness plus two feet, whichever is greater. |
|
(17) Fire Creek mineral resources are reported at a gold equivalent cut-off grade of 0.283 oz/ton. Metallurgical recoveries: 90% gold, 70% silver. |
|
(18) Hollister mineral resources, including the Hatter Graben are reported at a gold equivalent cut-off grade of 0.238 oz/ton. Metallurgical recoveries: 88% gold, 66% silver |
