NEWS RELEASE

Lundin Mining Provides Operational Outlook & Shareholder Returns Update

Toronto, November 30, 2020 (TSX: LUN; Nasdaq Stockholm: LUMI) Lundin Mining Corporation (“Lundin

Mining” or the “Company”) provides the following production guidance for the three-year period of 2021 through

2023, as well as cash cost, capital and exploration expenditure forecasts for 2021. Candelaria 2020 guidance has

been reintroduced and an update on the return to full production capacity at Chapada provided. Additionally,

the Company announces an anticipated 50% increase in the quarterly dividend and renewal of its Normal Course

Issuer Bid (“NCIB”), both pending final approvals as detailed herein.

• Copper production is forecast to increase over 25% in 2021, compared to the current 2020 guidance,

primarily on increasing grades at Candelaria and full-year uninterrupted contributions from both

Candelaria and Chapada.

• Zinc production is forecast to increase 30% in 2022, over 2021, as the Neves-Corvo Zinc Expansion Project

(“ZEP”) completes its ramp up in the first half of that year. The ZEP is planned to restart in January 2021.

• Nickel production is forecast to maintain current levels in 2021 before increasing over 10% in 2022 as

higher-grade ore from Eagle East contributes to the mill feed.

• Gold production is forecast to be 175,000 oz at the midpoint of 2021 guidance. Nearly 110,000 oz are

unencumbered.

1 Production guidance is based on certain estimates and assumptions, including but not limited to: Mineral Resources and Mineral Reserves, geological formations,

grade and continuity of deposits and metallurgical characteristics.

2 68% of Candelaria’s total gold and silver production are subject to a streaming agreement.

Candelaria 2020 Guidance & Chapada Update

• Candelaria: Collective agreements have now been reached with all five unions representing employees

at the Candelaria Copper Mining Complex in Chile. Ramp up of the operation to full capacity is underway

and is anticipated to be achieved in the coming weeks. Installation of the fourth, more powerful, ball mill

motor as part of the Candelaria Mill Optimization Project (“CMOP”) has been pulled forward and is to be

complete in December 2020. Following installation, the CMOP will be 100% complete.

With these consideration s, reintroduced 2020 copper production guidance is for 120,000-125,000 t at a

cash cost of $1. 50/lb. Cash cost guidance is net of credits from forecast gold production of 70,000-

75,000 oz, and includes expenses related to the strike and period of reduced operations. Full year 2020

capital expenditures are expected to be $ 225 million, of which $ 45 million is forecast for the fourth

quarter.

• Chapada: A return to full production capacity in December 2020 remains on track. The plant achiev ed

approximately 35% of nameplate capacity while operating only the SAG mill . Th roughput has further

improved since mid -November with the temporary installation of a motor generously loaned from

Samarco Mineração S.A. on the ball mill.

The first repaired motor is expected to be on site this week and a second motor is anticipated in mid -

December. A step -change increase to full production capacity is expected once these two motors are

available and installed.

Chapada 2020 production guidance remains 45,000-50,000 t of copper and 80,000-85,000 oz of gold.

Production Outlook 2021 - 2023

• Candelaria: Copper production for the next three years is forecast to increase over that of 2020 primarily

on improving copper head grade s and achievement of planned processing rates as the benefits of

reinvestment initiatives completed over the last several years are realized. Refinement to mine phasing

and operating plans have revised forecast 2021 copper and gold, and 2022 gold, production compared to

the prior outlook.

Copper production is forecast to be 172,000-182,000 t in 2021, a near 45% increase over forecast 2020

production. Production is to further increase to 180,000-190,000 t of copper in 2022 and maintain this

level in 2023. Over the next ten years copper production is forecast to average nearly 180,000 tpa.

Candelaria’s gold production is forecast to be 95,000-100,000 oz in 2021 and 2022, nearly a 35% increase

over the forecast for 2020. Gold production is to further increase in 2023 to 110,000-115,000 oz, averaging

nearly 100,000 oz per annum over the next ten years.

• Chapada: Forecast copper and gold production are generally consistent with the prior outlook . There

have been minor revisions on refinement of near-term operating plans. Production expectations are

based on the current 24 Mtpa throughput capacity with annual changes driven primarily by the forecast

grade profile.

Copper production is forecast to increase over 5% in 202 1 to 48,000-53,000 t. Copper production is to

further increase over 10% to 53,000-58,000 t in 2022, before reducing modestly to 50,000-55,000 t in 2023.

Chapada’s gold production is forecast to be 75,000-80,000 oz in 2021, 5,000 oz more than the prior outlook

for the year. Gold production is then forecast to modestly decline in 2022 and 2023 on the expected grade

profile. All of Chapada’s gold production remains unencumbered and receives full market pricing.

• Eagle: Nickel production is forecast to be 15,000-18,000 t in 2021 , consistent with the prior outlook as

Eagle East ore comprises the majority of the mill feed. Nickel production is f orecast to increase 12% in

2022 to 17,000-20,000 t before declining to 13,000-16,000 t in 2023 on nickel grades.

Eagle’s copper production is forecast to be 17,000-20,000 t in 2021, a 22% increase over the prior outlook.

Similar to nickel, as Eagle East ore grades begin to decline, forecast copper production is anticipated to be

15,000-18,000 t in 2022 and 12,000-15,000 t in 2023.

• Neves-Corvo: The ZEP is planned to restart in January 2021. Plans are to mobilize a smaller number of

contractors with an extended schedule to advance the project given the current safety requirements for

social distancing and other personnel limitations to safeguard and protect the workforce and local

communities from the spread of COVID -19. Forecast zinc and copper production over the three -year

outlook reflect this approach.

Zinc production in 2021 is forecast to be 70,000 -75,000 t as the ZEP construction is to be completed in

stages over the course of the year with production ramp up planned to commence in the fourth quarter.

Zinc production is forecast to increase 66% in 202 2 to 115,000-125,000 t as production ramp up is

completed in the first half of the year . W ith the ZEP contributing a full year of production at design

throughput, 2023 zinc production is forecast to be 145,000-155,000 t.

Copper production over the outlook period has been revised on refinement of the near-term mine plan,

impacting the forecast copper head grade.

• Zinkgruvan: Forecast zinc and copper production for 2021 and 2022 are generally consistent with the

prior outlook with minor revision on refinement of operating plans. Zinc production is forecast to increase

in 2023, compared to current and 2021-2022 levels, with planned mining of higher-grade orebodies.

2021 Cash Cost Guidance3

• Candelaria’s C1 cash costs are expected to reduce year-on-year to

$1.35/lb4 copper in 20 21, after by -product credits. By -product

credits have been adjusted for the terms of the streaming

agreement.

• At Chapada, C1 cash costs are expected to approximate $1.1 0/lb

copper in 2021 after significant gold by-product credits. Effects of

copper stream agreements are reflected in the realized copper

revenue.

• Eagle is expected to maintain the first quartile C1 cash costs of

$0.50/lb nickel in 2021, after by-product credits, as higher grades

from Eagle East reduce per pound unit costs.

• At Neves-Corvo, C1 cash costs for 20 21 are expected to

approximate $ 2.20/lb copper , after zinc and lead by -product

credits.

• Zinkgruvan’s C1 cash costs for 2021 are expected to approximate

$0.65/lb zinc after copper and lead by-product credits.

2021 Capital Expenditure Guidance

• Capital expenditures in 2021 are forecast to be $610 million on a 100% basis, which includes:

Capital Expenditures ($ millions)5 2021

Sustaining Capital

Candelaria (100% basis) 345

Chapada 65

Eagle 15

Neves-Corvo 65

Zinkgruvan 50

Total Sustaining Capital 540

Zinc Expansion Project (Neves-Corvo) 70

Total Capital Expenditures 610

3 C1 cash costs are based on various assumptions and estimates, including, but not limited to: production volumes, as noted above, commodity prices (2021 - Cu:

$2.95/lb, Zn: $1.00/lb, Pb: $0.85/lb, Au: $1,700/oz: Ag: $16.00/oz) foreign currency exchange rates (2021 - €/USD:1.20, USD/SEK:8.50, CLP/USD:675, USD/BRL:4.75) and

operating costs. All figures in are in US$ unless otherwise noted.

4 68% of Candelaria’s total gold and silver production are subject to a streaming agreement and as such C1 cash costs are calculated based on receipt of $416/oz and

$4.16/oz, respectively, on gold and silver sales in the year.

5 Forecast capital expenditures have been reported on a cash basis. Discrepancies may exist with other external reports which have been reported on an accrual basis.

and tailings dam expansion works.

Restart of the ZEP is on track for January 2021. The pre-production capital cost estimate of $430M (€360M)

remains unchanged. Current plans call for mobilization of a smaller number of contractors with an extended

schedule. A further $30 million of expansionary capital is forecast for 2022 , reflecting timing of payments,

to complete the project.

• Zinkgruvan: At Zinkgruvan, sustaining capital expenditures are estimated to total $50 million in 202 1.

Approximately $25M is for underground development with the remaining for in-fill drilling and improvement

initiatives.

2021 Exploration Investment Guidance

Exploration expenditures are planned to be $ 40 million in 20 21. Approximately $ 32 million will be spent

supporting significant in-mine and near-mine targets at our operations ($14 million at Candelaria, $6 million at

Zinkgruvan, $ 8 million at Chapada, and $ 4 million at Neves -Corvo). The remain ing $ 8 million is planned to

advance activities on exploration stage and new business development projects.

Shareholder Returns Update

Anticipated 50% Dividend Increase

A 50% increase in the quarterly dividend to C$0.0 6 per common share of the Company (“Common Shares”) , or

C$0.24 on an annualized basis, is anticipated to be declared with the release of 2020 full-year financial results in

February 2021 pending approval by the Company’s Board of Directors.

The anticipated increase is consistent with Lundin Mining’s strategy of providing leading returns for our

shareholders throughout the cycle. This expected increase reflects the strong free cashflow outlook from the

Company’s current operations. Lundin Mining is well positioned to enhance shareholder returns with a

progressive regular dividend, while maintaining balance sheet strength and investing in disciplined growth.

The dividend policy will continue to undergo periodic review by Lundin Mining management and the Board of

Directors and may change at any time depending on the Company’s earnings, financial requirements and other

factors existing at the time.

Normal Course Issuer Bid Renewal

Lundin Mining intends to renew it s NCIB to purchase up to 63,682,170 Common Shares on the Toronto Stock

Exchange (the “TSX”). The Company intends to continue to utilize the NCIB at its discretion to make opportunistic

purchases to create shareholder value and manage the number of outstanding Common Shares.

In connection with the NCIB renewal, Lundin Mining intends to enter into an automatic repurchase plan with its

designated broker to allow for the repurchase of Common Shares at times when the Company ordinarily would

not be active in the market due to its own internal trading blackout periods, insider tra ding rules or otherwise.

Any such plan entered into with the Company’s broker will be adopted in accordance with applicable Canadian

securities laws. The Company will determine parameters for such a plan based on market conditions, share price,

best use of available cash, and other factors.

The NCIB renewal has been approved by the Company’s Board of Directors; however, it is subject to acceptance

by the TSX and, if accepted, will be made in accordance with the applicable rules and policies of the TSX and

applicable Canadian securities laws. Under the NCIB, Common Shares may be repurchased in open market

transactions on the TSX and/or other Canadian exchanges, or by such other means as may be permitted by the

TSX and applicable Canadian securities laws. The price that Lundin Mining will pay for Common Shares in open

market transactions will be the market price at the time of purchase.

Pursuant to the NCIB renewal, which will commence following expiry of the current NCIB, it is expected that the

Company will be able to purchase up to 63,682,170 Common Shares, representing 10% of the total outstanding

Common Shares as of November 30, 2020, minus those Common Shares beneficially owned, or over which

control or direction is exercised by the Company, the sen ior officers and directors of the Company and every

shareholder who owns or exercises control or direction over more than 10% of the outstanding Common Shares,

over a period of twelve months commencing after TSX approval. In accordance with TSX rules, any daily

purchases, other than pursuant to a block purchase exception , on the TSX under the NCIB will be limited to a

maximum 25% of the average daily trading volume on the TSX for the six months ended November 30, 2020. Any

Common Shares that are purchased under the NCIB will be cancelled.

The actual number of Common Shares that may be purchased and the timing of such purchases will be

determined by the Company.

Under the Company’s current NCIB that commenced on December 9, 2019 and which expires on Decemb er 8,

2020, the Company previously sought and received approval from the TSX to purchase up to 63,707,653 Common

Shares. As of November 30, 2020, the Company has purchased 2,212,600 Common Shares under its current NCIB

through open market transactions at a weighted average price of approximately C$6.69 per Common Share.
