Description & History

Hecla’s Casa Berardi Mine is in western Quebec. In 2023, Casa Berardi produced 90,363 ounces of gold, a decrease of 29% over the prior year due to wildfire-related closures in June and lower underground tonnage mined, reflecting the decision to halt underground mining in the East Mine as part of the strategic change announced in August to transition to a surface operation during 2024. Open pit tons moved during the year set a record as the first phase of the in-house equipment fleet was commissioned. The mine is expected to produce 75,000 to 82,000 ounces of gold in 2024.  The current Mineral Reserve at Casa Berardi contains 1.3 million gold ounces.

Community Partner

Hecla Quebec is one of the largest private-sector employees and taxpayers in the communities near the Casa Berardi mine

The Casa Berardi Mine is situated 95 kilometres north of La Sarre, Quebec and straddles a 37-kilometre section of the Casa Berardi fault.

The Casa Berardi gold deposits are located along a five kilometre east-west mineralized corridor. They include the East and West mines and the Principal Zones. The Casa Berardi gold deposits can be classified as an Archean sedimentary-hosted lode gold deposit. The gold mineralization is superimposed on a continuous graphitic mudrock unit corresponding to the Casa Berardi Fault plane. Gold occurs mainly south of the Casa Berardi Fault and occasionally on both sides of the fault.

The West Mine shaft deepening project, which included construction of loading pockets and other related infrastructure, was completed in 2014, improving mine operations by providing additional access to the 118 and 123 zones for transporting ore and waste from underground. Excavation of the 985 drift (previously referred to as 1010) from the deepened shaft is underway. This drift is expected to improve ventilation and material handling and also provide a platform for deeper exploration drilling.

The Company began producing ore from the East Mine Crown Pillar (EMCP) pit in July 2016. Located near the East mine, the capital for this shallow pit project is expected to be $39 million over 5.5 years. The project has an expected IRR of 90%.

Safety and Health

Safety is an absolute priority for Hecla Quebec. The mining company has always aimed to innovate and invest for the benefit of the health and safety of its workers. The company has implemented an integrated health and safety management system throughout the company and attaches great importance to continuous improvement and innovation.

In 2018, the Casa Berardi mine was the first international mine to receive CORESafety certification from the US National Mining Association.

We achieved an OSHA* rate of 3.4 in 2018, down 15% from 2017. Our rate has dropped 50% over the past four years. These results are explained by even more rigor and management focused on the accountability of supervisors and workers.

* OSHA rate = (loss of time + temporary assignment + medical consultation) x 200,000 / number of hours worked

Environment

We also strive to use advanced mining technologies to minimize our impact during exploration, development, and operation and then restore the sites that have hosted our projects to productive land after mining activities cease. We are constantly seeking to innovate to develop new methods that allow us to coexist with nature while limiting the footprint of our activities.

To do this, we have adopted an environmental policy, the main pillars of which are:

  • Compliance with regulations
  • Continuous improvement
  • Pollution prevention
  • Risk management
Environment

Environment Policy

Hecla Quebec is determined to protect the environment responsibly and strives to minimize environmental impacts and risks for present and future generations. In order to fulfill our responsibilities, our goal is to provide the necessary resources to:

  • Design, operate, close and rehabilitate our facilities in accordance with applicable laws and regulations in order to meet recognized standards and even exceed them to respect Hecla's values
  • Continuously improve our safe, efficient and eco-responsible use of resources, products and materials
  • Promote the knowledge and empowerment of employees and contractors in the implementation of this policy through the use of environmental management systems
  • Periodically conduct environmental reviews and audits of operations and activities to ensure compliance, identify risks, reduce costs and liabilities, and improve sustainable operations
  • Strive to reduce energy and water consumption, continuously improving the efficiency of our facilities, projects, operations
  • Work in collaboration with educational institutions and other organizations for the purpose of research, development and use of best practices in technology and management to reduce impacts on the environment
Environment Policy

Towards Sustainable Mining Development (TSM)

Hecla Quebec participates in the sustainable mining development process of the Mining Associations of Canada and Quebec. In 2016, the QMA conducted an evaluation of the Towards Sustainable Mining Development initiative at the Casa Berardi site. An action plan has been put in place for the 6 protocols of the initiative, namely the management of mining residues, biodiversity, energy management, crisis management, relations with communities and management of health and safety. In 2017 and 2018, we continued to work on the implementation of management systems.

Towards Sustainable Mining Development (TSM)

Environmental Management System

Concerned about controlling the environmental impacts of our activities, Hecla Québec has implemented responsible practices and a continuous improvement program in terms of environmental performance. The environmental management system enables a structured, integrated and planned implementation of efforts to reduce our footprint.

Environmental Management System

Management of Energy And Greenhouse Gas Emissions

In order to limit its environmental footprint and reduce its operating costs, Hecla Quebec has established an action plan to improve its energy efficiency and reduce its greenhouse gas (GHG) emissions.

At the Casa Berardi mine, the use of autonomous trucks to transport ore underground has reduced energy consumption by 17% per vehicle.

Also at the Casa Berardi mine, we have equipped the mine's ventilation system with timers that are expected to reduce electricity consumption by 20% in 2019.

Management of Energy And Greenhouse Gas Emissions

Responsible Management of Mine Tailings

Hecla Québec attaches great importance to the responsible management of mine tailings. Our tailings storage facilities meet high safety and environmental criteria, as required by our Tailings Management Standard.

At the Casa Berardi mine, 15% of the tailings are used for backfilling underground. Waste rock is used for the construction of infrastructure such as roads and dikes in the tailings facility.

Residue management policy

The Casa Berardi mine tailings management policy aims to:

  • Ensure safe and environmentally friendly management for all life cycles from design to closure of facilities
  • Demonstrate our commitment and responsibilities to protect the safety and health of our employees and our communities
  • Minimize environmental effects and risks for present and future generations
  • Ensure the establishment of an effective management system
  • That all structures are stable and comply with regulatory requirements, industry best practices and that solids and liquids are contained within designated design areas
  • Understand the associated risks and put in place an emergency response plan
  • Provide the resources and training required to achieve the goals
  • Develop a water balance
  • Establish a continuous verification program
  • Make employees and contractors aware of commitments, encourage them to show leadership
  • Consult with stakeholders and communities of interest
  • Develop an OES manual (Operation, Maintenance and Monitoring)
Responsible Management of Mine Tailings

Water Management

Responsible water management is an absolute priority at Hecla Quebec. Water is essential for mining and its proper management is paramount to our operations and to our communities.

A robust program of sampling, quality analysis and audits allows us to ensure the quality of the water. The audits carried out help us to better understand the use, to identify the possibilities of reducing the consumption and recycling of water, as well as to reduce the volume of treated water in order to guarantee the protection of natural waters.

95% of the water used for the ore processing plant is recycled water from the process water pond.

Water Management

Conservation of Biodiversity

Hecla Québec has joined forces with the CRSNG-UQAT Industrial Chair on Biodiversity in Mining Context, along with nine other partners, in order to continue its efforts to innovate and develop new operating and exploration methods that make it possible to minimize its activities footprint.

Biodiversity conservation policy

Hecla Quebec is determined to responsibly protect the environment throughout the mine's life cycle, including the protection of biodiversity and the maintenance of healthy ecosystems. We are committed to minimizing the impacts of our activities on biodiversity, not carrying out any mining activities inside World Heritage sites and respecting the requirements for regulated protected areas. The environment department plans to ensure that this policy is implemented. In order to fulfill our responsibilities, we provide the necessary resources and skills to:

  • Meet regulatory requirements in terms of biodiversity conservation.
  • Develop, implement and continually improve the integration of biodiversity conservation into the environmental management system (EMS)
  • Take into consideration the conservation of biodiversity, in each stage of the mine's life cycle, targeting mitigation sequences: avoid, minimize, mitigate, compensate and during restoration, restore the vitality and diversity of ecosystems that will meet the needs of potential uses
  • Monitor and update annually, the action plan on biodiversity conservation, during the life cycle of the mine
  • Work in collaboration with educational institutions and other organizations, to create research projects, partnerships or information sharing on biodiversity conservation, science and traditional knowledge
  • Communicate transparently, constructively and mutually with the communities of interest, on biodiversity issues
  • Quantify, analyze, control and communicate the impacts of our activities on biodiversity and applicable mitigation measures
Conservation of Biodiversity

Gradual Closure

The open pit operation at the Casa Berardi mine requires the installation of new infrastructure such as mixed dumps for the storage of overburden (topsoil, clay and moraine) as well as waste rock. With the objectives of preserving and recycling resources, we chose to cover cell 2 with clay from the new pit. This layer of low permeability material is expected to minimize infiltration and allow the operation to begin the gradual restoration of the mine site.

Reporting requirements in the United States for disclosure of mineral properties as of December 31, 2020 and earlier are governed by the SEC’s Securities Act Industry Guide 7, entitled “Description of Property by Issuers Engaged or to be Engaged in Significant Mining Operations”; (Guide 7). Effective January 1, 2021, the SEC has issued new rules rescinding Guide 7. Mining companies are not required to comply with the new rules until the first fiscal year beginning on or after January 1, 2021. Thus, the Company will be required to comply with the new rules when filing its Form 10-K for the fiscal year ended December 31, 2021. The Company is also a “reporting issuer”; under Canadian securities laws, which require estimates of mineral resources and reserves to be prepared in accordance with Canadian National Instrument 43-101 (NI 43-101). NI 43-101 requires all disclosure of estimates of potential mineral resources and reserves to be disclosed in accordance with its requirements. Such Canadian information is included herein to satisfy the Company’s “public disclosure”; obligations under Regulation FD of the SEC and to provide U.S. holders with ready access to information publicly available in Canada.

Reporting requirements in the United States for disclosure of mineral properties under Guide 7 compared to the new SEC rules (Item 1300 of Regulation S-K under the Securities and Exchange Act of 1934) and the requirements in Canada under NI 43-101 standards are substantially different. This document contains a summary of certain estimates of the Company, not only of Proven and Probable reserves within the meaning of Guide 7, but also of mineral resource and mineral reserve estimates estimated in accordance with the new SEC rules and definitional standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in NI 43-101. Under Guide 7, the term “reserve”; means that part of a mineral deposit that can be economically and legally extracted or produced at the time of the reserve determination. The term “economically”, as used in the definition of reserve, means that profitable extraction or production has been established or analytically demonstrated to be viable and justifiable under reasonable investment and market assumptions. The term “legally”, as used in the definition of reserve, does not imply that all permits needed for mining and processing have been obtained or that other legal issues have been completely resolved. However, for a reserve to exist, Hecla must have a justifiable expectation, based on applicable laws and regulations, that issuance of permits or resolution of legal issues necessary for mining and processing at a particular deposit will be accomplished in the ordinary course and in a timeframe consistent with Hecla’s current mine plans. The terms “Measured resources”, “Indicated resources,”; and “Inferred resources”; are mining terms as defined in accordance with the new SEC rules and NI 43-101. These terms are not defined under Guide 7 and prior to January 1, 2021, were not normally permitted to be used in reports and registration statements filed with the SEC in the United States, except where required to be disclosed by foreign law. The term “resource”; does not equate to the term “reserve”;. Under Guide 7, the material described herein as “Indicated resources”; and “Measured resources”; would be characterized as “mineralized material”; and is permitted to be disclosed in tonnage and grade only, not ounces. The category of “inferred resources”; is not recognized by Guide 7. Investors are cautioned not to assume that any part or all of the mineral deposits in such categories will ever be converted into Proven or Probable reserves. “Resources”; have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of such a “resource”; will ever be upgraded to a higher category or will ever be economically extracted. Investors are cautioned not to assume that all or any part of a “resource”; exists or is economically or legally mineable. Investors are also especially cautioned that the mere fact that such resources may be referred to in ounces of silver and/or gold, rather than in tons of mineralization and grades of silver and/or gold estimated per ton, is not an indication that such material will ever result in mined ore which is processed into commercial silver or gold.

Operational Highlights

Production

Casa Berardi is an underground trackless mine accessed by declines and a shaft. The mining methods are longhole transversal stoping in 10 meters or more mineralization width, and longitudinal retreat stoping in narrower ore bodies. The mineralized zones put in reserves are of varying thickness, ranging from a few tens of meters to 3 meters, which is the minimum mining width. Most of the hanging walls are sub-vertical (55° to 85°) with typically the graphitic Casa Berardi fault at the footwall. In addition, ore is being produced from the East Mine Crown Pillar (EMCP) pit located near the East mine.

The mine has produced approximately 2.0 million recovered gold ounces since commencing production in 1988, including about 1.0 million recovered ounces since production recommenced in November 2006.

Exploration

In 2024, of the $25.4 million planned for exploration and pre-development spend, 3.8% is planned for Casa Berardi.   Limited underground exploration will be focused in the Principal Area to expand underground mining areas in the short term and test target areas north and south of the Casa Berardi Fault.

Future Plans

The Company has been focused on long-term operational improvement at Casa Berardi.  The transition from underground to fully open-pit mining is underway, and results are exceeding expectations so far.

Casa Berardi Social
& Economic Benefit

Casa Berardi provides large social and economic benefits in its community through volunteerism, investment, and engagement. In 2022, Hecla Quebec was one of the largest private-sector employees and taxpayers in the communities near the mine with a direct economic impact of more than $278 million including over $64 million in wages, $40 million in taxes and fees, and $174 million in purchases from vendors.
