Responsible Mining

Tailings Management

  • employ a comprehensive and integrated approach to tailings management. This provides confidence that potential environmental and social impacts can be reliably identified and minimized
  • our Responsible Mining Management System includes a specific Tailings Management Technical Standard. This standard requires that each operation ensure tailings facilities and major water-retention dams are planned, designed, constructed, operated, decommissioned and closed in such a manner that they are stable. It also ensures that all aspects comply with regulatory requirements, conform to Company standards and accepted international practices and adhere to any commitments made to local stakeholders
  • Lundin Mining is committed to the implementation of the Global Industry Standard on Tailings Management (GISTM), which is the first global standard on tailings management. Lundin Mining plans for to be in full conformance with the GISTM within five years of August 5, 2020.

Our Facilities

  • of the five Lundin Mining operations, Eagle Mine is the only operation that does not have a constructed tailings impoundment with dams
  • the five active tailings facilities use various construction techniques for the main and secondary or perimeter dams, but none use upstream construction
  • also maintains and monitors six inactive/closed tailings facilities

A full list of tailings facilities that Lundin Mining manages, including information on tailings management, construction method, maximum dam height and volume, can be found in our Tailings Management Information Sheetin OurApproach to Tailings Management.

Responsible Mining

Climate Change, Energy and CHG Emissions

  • recognize the need for effective approaches to managing climate-related responsibilities, especially in consideration of the remote locations in which we operate, the energy-intensive nature of our industry, and the sometimes-limited availability of renewable energy in national energy supply
  • in 2019, we scoped and developed a corporate climate change adaptation and mitigation planning toolkit that will enhance the resilience of our operations by formalizing site-level,climate-related risk assessments for the development and prioritization of climate adaptation strategies
  • Lundin Mining's GHG emissions broadly correlate with our energy consumption trends. Our market-based Scope 2 emissions continue to benefit from
    Zinkgruvan's investment in a 100% renewable electricity supply since 2017 supported by a Guarantee of Origin. In the future, we will also realize the positive effect of Candelaria's contractual agreement with its supplier for an increase in renewables to a minimum of 80% in the energy mix, prioritizing wind and solar energy, commencing in 2023.
  • reduction in energy intensity and GHG emissions intensity, per tonne rock mined, from 2016 to 2019. Chapada has the lowest intensity levels arising from the movement of significant quantities of material over relatively short distances. Candelaria's low energy intensity levels also reflect the large tonnage of ore and waste rock excavated. Our remaining underground operations do not benefit from such efficiencies of scale, especially those located in colder climates that require additional energy for heating

Retain An Above Average 'B' CDP Score

  • we report annually to the CDP Climate Change and Forestry programs, aligned with the Task Force on Climate-related Financial Disclosures
  • retained an above average 'B' score again in 2019, a significant achievement within the context of a North America regional average score of 'D' and a metallic mineral mining sector average score of 'C'

18

Responsible Mining

Water Stewardship

  • continue to make water stewardship gains, achieving measurable reductions in fresh water use and increases in water re-use in 2019. Total fresh surface water withdrawal decreased 7% in 2019 compared to 2018
  • committed to improvements in water assessment and management practices, evaluating water-use efficiency, initiatives to prevent unnecessary pressure on shared resources and measures to minimize environmental and social impacts
  • all operations continuously seek to improve their site water balances and water management plans, implementing comprehensive water management planning processes
  • future efforts in water management will include an increased focus on the resilience of site water management infrastructure, and processes and procedures concerning the potential for more frequent and extreme weather events in changing climatic environments

Candelaria's operational water requirements met entirely through supply from its sea water desalination facility

  • the operation maintains a strong focus on water use efficiency
  • in 2019 overall water withdrawal was reduced by 2.2 million m3
  • use of treated municipal wastewater ceased 2019, significantly earlier than the 2027 regulatory requirement, enabling these resources to be redirected to other uses in this water-scarce region

The Measured and Indicated Mineral Resource estimates are inclusive of those Mineral Resource estimates modified to produce the Mineral Reserve estimates. All estimates of the Company are prepared as at June 30, 2020. Estimates for all operations are prepared by or under the supervision of a Qualified Person as defined in NI 43-101 or have been audited by independent Qualified Persons on behalf of the Company.

Mineral Reserves for all active mines have been estimated using metal prices of US$3.00/lb copper, US$1.00/lb zinc, US$0.95/lb lead, US$6.50/lb nickel and US$1,300/oz gold. Exchange rates used were EUR/USD 1.25, USD/SEK 7.00, USD/CLP 600 and USD/BRL 4.00. For the Suruca gold deposit Mineral Reserve, the metal prices used were US$3.00/lb copper and US$1,250/oz gold and an exchange rate of USD/BRL 3.95.

Candelaria and La Española open pit Mineral Resource estimates are reported within a conceptual pit shell based on metal prices of US$3.45/lb copper and US$1,300/oz gold with cut-off grades of 0.15% and 0.17% copper, respectively. Candelaria underground Mineral Resources are estimated at a cut-off grade of 0.45% copper within confining grades shells of 0.4% copper. Mineral Reserves for the Candelaria open pit, Española open pit and underground for the Candelaria property are estimated at cut-off grades of 0.16%, 0.19% and 0.50% copper, respectively. Underground Mineral Reserves for the Ojos del Salado property, Santos and Alcaparrosa mines, are estimated at cut-off grades of 0.55% copper and 0.60% copper respectively. Chapada and Suruca SW copper-gold Mineral Resource estimates are reported within a conceptual pit shell based on metal prices of US$3.45/lb copper and US$1,495/oz gold and at a variable Net Smelter Return (NSR) marginal cut-off averaging US$4.08 per tonne. For the Suruca gold only Mineral Resource estimates, cut-off grades of 0.16g/t gold for oxides and 0.23g/t for sulphides were used. Mineral Reserves for the Chapada open pit are estimated at a NSR cut-off of US$4.73 per tonne. For the Suruca gold only Mineral Reserve estimates cutoff grades of 0.19g/t gold for oxides and 0.30g/t for sulphides are used. Eagle Mineral Resources and Reserves are reported above a fixed NSR cut-off of US$108/t. The Eagle East Mineral Resources are reported above a fixed NSR cut-off of US$142/t and the Mineral Reserves are reported above US$142/t for long-hole stopes and US$150/t for cut-and-fill stopes. The NSR is calculated on a recovered payable basis considering nickel, copper, cobalt, gold and PGM grades, metallurgical recoveries, prices and realization costs. The Neves-Corvo Mineral Resources are estimated above cut-off grades of 1.0% for copper and 4.5% for zinc. The Neves-Corvo copper and zinc Mineral Reserve estimates have been calculated using variable NSR values based on area and mining method. The NSR is calculated on a recovered payable basis considering copper, lead, zinc and silver grades, metallurgical recoveries, prices and realization costs. The Neves-Corvo copper Mineral Reserves are estimated above a site average cutoff of EUR 42.0/t (grade equivalent to 1.34% copper).
