The Company also generated adjusted earnings 1 of $16.0 million ($0.02 per share) and adjusted EBITDA 1 of $162.2 million in the second quarter. Adjusted earnings were $141.7 million ($0.1 8 per share) and adjusted EBITDA were $499.1 million for the six months ended Jun e 30, 2023. Adjusted operating cash flow 1 were $110.6 million ($0.14 per share) and $345.7 million ($0.45 per share) for the three and six months ended June 30, 2023. “Overall, we are pleased with the performance of our operations during the second quarte r. We are currently tracking at the midpoint or higher for copper, gold and nickel guidance and the lower end for zinc. We generated adjusted EBITDA of over $160 million despite a decline in metal prices early in the second quarter and resulting provisional pricing adjustments. Lundin Mining’s earnings and cash -generation potential has further increased with the addition of Caserones which closed early in the third quarter. On a 100% proforma basis, including Caserones, Lundin Mining’s operations produced a pproximately 280,000 tonnes of copper-equivalent metal in the first half of this year. Caserones produced approximately 70,000 tonnes of copper in the first half of the year and is off to a strong start in the third quarter,” commented Peter Rockandel, CEO. Mr. Rockandel added, “With the free cash flow from operations, the new $800 million Term Loan, and the existing $1.75 billion revolving credit facility, Lundin Mining retains a strong balance sheet and significant liquidity to progress growth projects.” Summary Financial Results Three months ended June 30, Six months ended June 30, US$ Millions (except per share amounts) 2023 2022 2023 2022 Revenue 588.5 590.2 1,339.9 1,581.3 Gross profit 52.8 46.0 266.2 524.8 Attributable net earnings (loss)2 59.1 (52.6) 205.7 292.5 Net earnings (loss) 61.3 (48.6) 226.6 329.5 Adjusted earnings 1,2 16.0 (35.3) 141.7 260.3 Adjusted EBITDA1 162.2 148.6 499.1 736.4 Basic and diluted earnings per share ("EPS")2 0.08 (0.07) 0.27 0.39 Adjusted EPS1,2 0.02 (0.05) 0.18 0.35 Cash flow from operations 194.8 366.4 406.7 683.7 Adjusted operating cash flow1 110.6 49.7 345.7 522.6 Adjusted operating cash flow per share1 0.14 0.06 0.45 0.70 Free cash flow from operations1 20.7 266.3 91.8 461.1 Free cash flow1 (84.6) 149.1 (118.8) 321.5 Cash and cash equivalents 190.2 498.2 190.2 498.2 Net debt1 (229.8) 469.9 (229.8) 469.9 1 These are non-GAAP measures.

Overall, the operations performed well during the second quarter of 2023 and the Company remains on track to achieve production guidance. Operational Performance Candelaria (80% owned): Candelaria produced 36,952 tonnes of copper, and approximately 21,000 ounces of gold in concentrate on a 100% basis in the quarter. Copper production was lower than the prior year quarter due to grades partially offset by higher throughput. Gold productio n was lower than the prior year quarter due to recoveries. Current quarter production costs and copper cash cost1 of $2.14/lb were higher than the prior year quarter largely owing to higher contractor and maintenance costs. Cash cost was further impacted by lower sales volumes. Chapada (100% owned): Chapada produced 10,697 tonnes of copper and approximately 13,000 ounces of gold in concentrate in the quarter. Copper production was higher than the prior year quarter primarily due to higher recoveries in the quarter. Current quarter production for both metals was better than the first quarter of 2023, due to higher grades and recoveries. In aggregate, production costs were higher than the prior year comparable quarter due to higher sales volumes achieved, wh ile the higher sales volumes also led to improvement on a unit basis with a copper cash cost of$2.69/lb for the quarter. Eagle (100% owned): During the quarter Eagle produced 4,686 tonnes of nickel and 3,881 tonnes of copper which were lower than the prio r year quarter due to lower grades and lower throughput. Production costs were lower than the comparable prior year quarter due to lower consumable costs. Nickel cash cost in the quarter of $1.88/lb was higher than the prior year quarter due primarily to lower by-product copper price and lower sales volumes. Neves-Corvo (100% owned): Neves-Corvo produced 7,610 tonnes of copper for the quarter and 24,177 tonnes of zinc. Copper production was lower than the prior year comparable quarter, due to lower grades, while zinc production was higher primarily due to increased throughput and recoveries driven by the ramp -up of the Zinc Expansion Project (“ZEP”). Production costs were comparable to the prior year quarter. Copper cash cost of $3.99/lb was higher than the prior year quarter due primarily to lower copper sales volumes. Zinkgruvan (100% owned): Zinc production of 11,938 tonnes and lead production of 3,816 tonnes were lower than the prior year quarter due to lower throughput due to a shut -down of the mill to perform the planned implementation of the sequential flotation circuit. Copper production of 917 tonnes was higher than the prior year quarter due to higher grades. Production costs were lower than the prior year quarter due to lower mine and mill costs . Zinc cash cost of $0.24/lb was lower than the prior year quarter due to lower production costs.

The Company paid an aggregate of approximately $800 million in cash consideration at closing. Remaining deferred cash consideration of $150 million will be payable in installments over the six ‑year period following the closing date. Lundin Mining also has the right to acquire up to an additional 19% interest in Lumina Copper for $350 million over a five-year period commencing on the first anniversary of the date of closing . A technical report for the Caserones mine titled “Caserones Mining Operation, Chile, NI 43-101 Technical Report on the Caserones Mining Operation” was filed under the Company's profile. • On July 27, 2023, the Company announced it had obtained a three -year term loan ("Term Loan") in a principal amount of $800 million with an additional $400 million accordion and closing of up to an additional 19% interest in Lumina Copper. Financial Performance • Gross profit for the quarter ended June 30, 2023 was $52.8 million, an increase of $6.8 million and largely comparable to the prior year quarter. On a year -to-date basis, gross profit for the peri od ended June 30, 2023 was $266.2 million and was lower than the prior year period due to lower sales volumes and lower metal prices. • For the three months ended June 30, 2023, net earnings of $61.3 million were $109.9 million higher than the prior year quarter due primarily to lower general exploration and business development costs and lower income taxes. On a year -to-date basis net earnings of $226.6 million were lower than the prior year period due to lower gross profit resulting from lower realized prices, partially offset by lower taxes. • Adjusted earnings for the three months ended June 30, 2023, of $16.0 million were $51.3 million higher than the adjusted loss of the prior year quarter due to the same factors as the change in net earnings described above. On a year-to-date basis adjusted earnings of $141.7 million were lower than the prior year period due to lower gross profit partially offset by lower income taxes. Financial Position and Financing • Cash and cash equiva lents as at June 30, 2023 was $190.2 million. Cash flow from operations of $194.8 million was used to fund investing activities of $283.5 million. Cash from financing activities was $99.9 million, which was comprised primarily of the proceeds from debt on a net basis partially offset by dividends paid to shareholders. Cash and cash equivalents remained relatively unchanged during the six months ended June 30, 2023. • As at June 30, 2023, the Company had a net debt balance of $229.8 million. • As at August 2, 2023, the Company had cash and net debt balances of approximately $2 70.0 million and $930.0 million, respectively. The net debt increase was attributable to debt financing of the acquisition of Caserones. ===== SIDA 4 ===== Outlook Overall, the operations performed well during the second quarter of 2023. The Company is currently tracking to the midpoint or higher for copper, gold and nickel guidance and the lower end for zinc. Production continues to be weighted to the second half of the year. Candelaria and Eagle production is forecast to be modestly weighted to the second half of the year, primarily owing to mine sequencing and the resultant grade profiles. Chapada production is forecast to be weighted to the second half of the year due to first half seasonal operating considerations, and forecast grade and recovery profiles. Expected cash costs remain consistent with reported guidance for Candelaria, Caserones and Neves -Corvo. Chapada’s cash cost guidance range has been improved to $2.35 - $2.55/lb of copper, reflecting lower pricing of consumables. Eagle’s forecast nickel cash cost guidance has been increased to $2.30 - $2.45/lb of nickel. While Eagle’s overall operating costs remain consistent with the Company’s previou s expectations, nickel cash cost guidance has been increased primarily driven by lower by-product credits, mainly pricing. Zinkgruvan’s cash cost guidance has been improved to $0.45 - $0.50/lb of zinc, reflecting greater by-product credits. A reduction in capital expenditure guidance is expected for the remainder of the year as the timing of several projects at Candelaria has been deferred into next year. At Josemaria, foreign exchange, a delay in planned equipment deliveries and reduced activities have lowered capital spend guidance. 2023 Production and Cash Cost Guidance Previous Guidancea Revised Guidance (contained metal) Production Cash Cost ($/lb) Production Cash Cost ($/lb)b Copper (t) Candelaria (100%) 145,000 - 155,000 1.80 – 1.95c 145,000 - 155,000 1.80 – 1.95c Caserones (100%)e 60,000 - 65,000 2.30 - 2.45 60,000 - 65,000 2.30 - 2.45 Chapada 43,000 - 48,000 2.55 – 2.75d 43,000 - 48,000 2.35 – 2.55d Eagle 12,000 - 15,000 12,000 - 15,000 Neves-Corvo 33,000 - 38,000 2.10 – 2.30c 33,000 - 38,000 2.10 – 2.30c Zinkgruvan 3,000 - 4,000 3,000 - 4,000 Total 296,000 - 325,000 296,000 - 325,000 Zinc (t) Neves-Corvo 100,000 - 110,000 100,000 - 110,000 Zinkgruvan 80,000 - 85,000 0.60 – 0.65c 80,000 - 85,000 0.45 – 0.50c Total 180,000 - 195,000 180,000 - 195,000 Molybdenum (t) Caserones (100%)e 1,500 - 2,000 1,500 - 2,000 Gold (koz) Candelaria (100%) 85 - 90 85 - 90 Chapada 55 - 60 55 - 60 Total 140 - 150 140 - 150 Nickel (t) Eagle 13,000 - 16,000 1.50 – 1.65 13,000 - 16,000 2.30 – 2.45 a.

Overall, the operations performed well during the second quarter of 2023 and the Company remains on track to achieve production guidance. Operational Performance Candelaria (80% owned): Candelaria produced 36,952 tonnes of copper, and approximately 21,000 ounces of gold in concentrate on a 100% basis in the quarter. Copper production was lower than the prior year quarter due to grades partially offset by higher throughput. Gold production was lower than the prior year quarter due to recoveries. Current quarter production costs and copper cash cost1 of $2.14/lb were higher than the prior year quarter largely owing to higher contractor and maintenance costs. Cash cost was further impacted by lower sales volumes. Chapada (100% owned): Chapada produced 10,697 tonnes of copper and approximately 13,000 ounces of gold in concentrate in the quarter. Copper production was higher than the prior year quar ter primarily due to higher recoveries in the quarter. Current quarter production for both metals was better than the first quarter of 2023, due to higher grades and recoveries. In aggregate, production costs were higher than the prior year comparable quarter due to higher sales volumes achieved, while the higher sales volumes also led to improvement on a unit basis with a copper cash cost of $2.69/lb for the quarter. Eagle (100% owned): During the quarter Eagle produced 4,686 tonnes of nickel and 3,881 tonnes of copper which were lower than the prior year quarter due to lower grades and lower throughput. Production costs were lower than the comparable prior year quarter due to lower consumable costs. Nickel cash cost in the quarter of $1.88/lb was higher t han the prior year quarter due primarily to lower by-product copper price and lower sales volumes. Neves-Corvo (100% owned): Neves-Corvo produced 7,610 tonnes of copper for the quarter and 24,177 tonnes of zinc. Copper production was lower than the prior year comparable quarter, due to lower grades, while zinc production was higher primarily due to increased throughput and reco veries driven by the ramp -up of the Zinc Expansion Project (“ZEP”). Production costs were comparable to the prior year quarter. Copper cash cost of $3.99/lb was higher than the prior year quarter due primarily to lower copper sales volumes. Zinkgruvan (100% owned): Zinc production of 11,938 tonnes and lead production of 3,816 tonnes were lower than the prior year quarter due to lower throughput due to a shut-down of the mill to perform the planned implementation of the sequential flotation circuit. Copper production of 917 tonnes was higher than the prior year quarter due to higher grades. Production costs were lower than the prior year quarter due to lower mine and mill costs. Zinc cash cost of $0.24/lb was lower than the prior year quarter due to lower production costs.

The Company paid an aggregate of approximately $800 million in cash consideration at closing. Remaining deferred cash consideration of $150 million will be payable in installments over the six ‑year period following the closing date. Lundin Mining also has the right to acquire up to an additional 19% interest in Lumina Copper for $350 million over a five-year period commencing on the first anniversary of the date of closing. A technical report for the Caserones mine titled “Caserones Mining Operation, Chile, NI 43 -101 Technical Report on the Caserones Mining Operation” was filed under the Company's profile. • On July 27, 2023, the Company announced it had obtained a three-year term loan ("Term Loan") in a principal amount of $800 million with an additional $400 million accordion and closing of up to an additional 19% interest in Lumina Copper. Financial Performance • Gross profit for the quarter ended June 30, 2023 was $52.8 million, an increase of $6.8 million and largely comparable to the prior year quarter. On a year -to-date basis, gross profit for the period ended June 30, 2023 was $266.2 million and was lower than the prior year period due to lower sales volumes and lower metal prices. • For the three months ended June 30, 2023, net earnings of $61.3 million were $109.9 million higher than the prior year quarter due primarily to lower general exploration and business development costs and lower income taxes. On a year - to-date basis net earnings of $226.6 million were lower than the prior year period due to lower gross profit resulting from lower realized prices, partially offset by lower taxes. • Adjusted earnings 1 for the three months ended June 30, 2023, of $16.0 million were $51.3 milli on higher than the adjusted loss of the prior year quarter due to the same factors as the change in net earnings described above. On a year- to-date basis adjusted earnings of $141.7 million were lower than the prior year period due to lower gross profit partially offset by lower income taxes. Financial Position and Financing • Cash and cash equivalents as at June 30, 2023 was $190.2 million. Cash flow from operations of $194.8 million was used to fund investing activities of $283.5 million. Cash from financing activities was $99.9 million which was comprised primarily of the proceeds from debt on a net basis partially offset b y dividends paid to shareholders. Cash and cash equivalents remained relatively unchanged during the six months ended June 30, 2023. • As at June 30, 2023, the Company had a net debt1 balance of $229.8 million. • As at August 2, 2023, the Company had cash and net debt balances of approximately $ 270.0 million and $930.0 million, respectively. The net debt increase was attributable to debt financing of the acquisition of Caserones. ===== SIDA 16 ===== 3 Outlook Overall, the operations performed well during the second quarter of 2023. The Company is currently tracking to the midpoint or higher for copper, gold and nickel guidance and the lower end for zinc. Production continues to be weighted to the second half of the year. Candelaria and Eagle production is forecast to be modestly weighted to the second half of the year, primarily owing to mine sequencing and the resultant grade profiles. Chapada production is forecast to be weighted to the second half of the year due to the first half seasonal operating considerations and forecast grade and recovery profiles. Expected cash costs remain consistent with reported guidance for Candelaria, Caserones and Neves -Corvo. Chapada’s cash cost guidance range has been improved to $2.35 - $2.55/lb of copper, reflecting lower pricing of consumables. Eagle’s forecast nickel cash cost guidance has been increased to $2.30 - $2.45/lb of nickel. While Eagle’s overall operating costs remain consistent with the Company’s previous expectations, nickel cash cost guidance has been increased primarily driven by lower by-product credits, mainly pricing. Zinkgruvan’s cash cost guidance has been improved to $0.45 - $0.50/lb of zinc, reflecting greater by-product credits. A reduction in capital expenditure guidance is expected for the remainder of the year as timing of several projects at Candelaria have been deferred into next year. At Josemaria, foreign exchange, a delay in planned equipment deliveries and reduced activities have lowered capital spend guidance. 2023 Production and Cash Cost Guidance Guidancea Revised Guidance (contained metal) Production Cash Cost ($/lb)b Production Cash Cost ($/lb)b Copper (t) Candelaria (100%) 145,000 – 155,000 1.80 – 1.95c 145,000 – 155,000 1.80 – 1.95c Caserones (100%)e 60,000 – 65,000 2.30 – 2.45 60,000 – 65,000 2.30 – 2.45 Chapada 43,000 – 48,000 2.55 – 2.75d 43,000 – 48,000 2.35 – 2.55d Eagle 12,000 – 15,000 12,000 – 15,000 Neves-Corvo 33,000 – 38,000 2.10 – 2.30c 33,000 – 38,000 2.10 – 2.30c Zinkgruvan 3,000 – 4,000 3,000 – 4,000 Total 296,000 – 325,000 296,000 – 325,000 Zinc (t) Neves-Corvo 100,000 – 110,000 100,000 – 110,000 Zinkgruvan 80,000 – 85,000 0.60 – 0.65c 80,000 – 85,000 0.45 – 0.50c Total 180,000 – 195,000 180,000 – 195,000 Molybdenum (t) Caserones (100%)e 1,500 – 2,000 1,500 – 2,000 Gold (koz) Candelaria (100%) 85 – 90 85 – 90 Chapada 55 – 60 55 – 60 Total 140 – 150 140 – 150 Nickel (t) Eagle 13,000 – 16,000 1.50 – 1.65 13,000 – 16,000 2.30 – 2.45 a.

On a year -to-date basis revenue was lower than the prior year period primarily as a result of lower sales volumes ($126.6 million) and realized metal prices ($88.9 million). Revenue from gold and silver for the three and six months ended June 30, 2023 includes the partial recognition of an upfront purchase price on the sale of precious metals streams for Candelaria, Neves -Corvo, and Zinkgruvan as well as the cash proceeds which amount to approximately $425/oz for gold and between $4.25/oz and $4.57/oz for silver. Chapada’s copper revenue includes the recognition of deferred revenue from copper streams acquired with the Chapada mine, as well as the cash proceeds of 30% of the market price of the copper sold under the streams. Revenue is recorded using the metal pri ce received for sales that settle during the reporting period. For sales that have not been settled, an estimate is used based on the expected month of settlement and the forward price of the metal at the end of the reporting period. The difference between the estimate and the final price received is recognized by adjusting revenue in the period in which the sale is settled. Settlement dates can range from one to six months after shipment. ===== SIDA 21 ===== 8 Provisionally Valued Revenue as of June 30, 2023 Metal Payable metal Valued at Copper 82,405 t $3.77 /lb Zinc 27,637 t $1.08 /lb Gold 35 koz $1,929 /oz Nickel 1,668 t $9.25 /lb Quarterly Reconciliation of Realized Prices Three months ended June 30, 2023 ($ thousands) Copper Zinc Gold Nickel Total Current period sales1 473,543 74,219 65,401 78,486 691,649 Prior period price adjustments (53,338) (20,341) (2,949) 2,039 (74,589) 420,205 53,878 62,452 80,525 617,060 Other metal sales 46,124 Copper stream cash effect (4,253) Gold stream cash effect (20,923) Less: Treatment & refining charges (49,477) Total Revenue 588,531 Payable Metal 56,633 t 29,499 t 34 koz 3,859 t Current period sales1,2 $3.79 $1.14 $1,929 $9.23 Prior period adjustments2 (0.42) (0.31) (87) 0.24 Realized prices2, 3 $3.37 /lb $0.83 /lb $1,842 /oz $9.47 /lb Three months ended June 30, 2022 Copper Zinc Gold Nickel Total Current period sales1 502,541 111,814 58,808 102,349 775,512 Prior period price adjustments (127,376) (6,432) (5,652) (31,525) (170,985) 375,165 105,382 53,156 70,824 604,527 Other metal sales 56,114 Copper stream cash effect (5,244) Gold stream cash effect (20,181) Less: Treatment & refining charges (44,995) Total Revenue 590,221 Payable Metal 60,239 t 34,814 t 32 koz 4,206 t Current period sales1,2 $3.78 $1.46 $1,825 $11.04 Prior period adjustments2 (0.96) (0.09) (176) (3.40) Realized prices2, 3 $2.82 /lb $1.37 /lb $1,649 /oz $7.64 /lb 1.

On a year -to-date basis, production costs of $823.0 million was an increase of $38.3 million over the prior year comparable period primarily due to increased contractor and maintenance costs at Candelaria. Depreciation, Depletion and Amortization For the three and six months ended June 30, 2023 depreciation, depletion and amortization expense decreased compared to the prior year comparative periods, primarily attributable to an extended life of mine at Eagle and reduced Candelaria deferred stripping amortization.

During the current quarter, exploration costs were spent primarily on in -mine and near -mine targets at the Company’s operations. Geophysical surveys were conducted at Chapada, Eagle and Zinkgruvan. Drilling at Candelaria was divided between Ojos distri ct and Candelaria Underground with six rigs. Exploration drilling at Neves -Corvo and Zinkgruvan was primarily focused along near -mine mineralized trends; Drilling at Chapada has primarily focused on Saúva and the Chapada District with four drill rigs opera ting during the quarter. Drilling at Eagle commenced during the second quarter with geophysical targeting support which will continue into the third quarter. Other Income Net other income for the quarter and six months ende d June 30, 2023 increased compared to the prior year comparable periods due to foreign exchange, trading gains on debt and equity investments and gains on foreign currency contracts. This was partially offset by Ojos del Salado sinkhole expenses and a comparatively lower gain on disposal in the current year related to a subsidiary sold in a prior period. Foreign exchange gains and losses recorded in other income primarily resulted from foreign exchange revaluation of working capital denomin ated in foreign currencies.

Year -to-date, gross profit was lower than the prior year period due to higher production costs and lower sales volumes. Production Copper production for the three and six months ended June 30, 2023 was lower than the prior year quarter and year-to-date period due to lower grades from the open pit, partially offset by higher throughput. Gold production in the current quarter was below the prior year quarter, due to lower recoveries and on a year-to-date basis, gold production was comparable to the prior year period. Annual copper and gold production are on track to achieve guidance. Production Costs and Cash Cost Production costs and copper cash cost for the three and six months ended June 30, 2023 were higher than the prior year quarter, mainly due to higher contractor services and higher maintenance costs partially mitigated by contracted lower energy costs. Cash cost was further impacted by lower copper sales volumes. Annual copper cash cost guidance has remained unchanged from previous guidance. AISC for the three and six months ended June 30, 2023 were higher than the prior year periods due to higher cash cost and higher sustaining capital expenditures.

Year -to-date, gross profit was lower than the prior year period, due to higher depreciation expense. Production Copper production for the t hree and six months ended June 30, 2023 was higher than the prior year periods due to higher recoveries in the second quarter of 2023. Gold production in the quarter and year -to-date was lower than the prior year periods due to lower grades. Production of both metals in the current quarter were higher than production in the first quarter. Both metals are on track to meet annual production guidance. Production Costs and Cash Cost Current quarter production costs were higher than the prior year quarter due primarily to higher volumes sold. Year-to-date, production costs are comparable to the prior year period. Copper cash cost in the second quarter was better than the prior year quarter due to higher sales volumes. Year-to-date, cash cost was higher than 2022 due to lower sales volumes. Annual cash cost guidance has improved from $2.55 - $2.75/lb to $2.35 - $2.55/lb of copper due lower pricing of consumables. AISC was lower in the current quarter and higher year -to-date, attributable to cash cost movements described above. Projects The Company is continuing to evaluate options for long -term mine and plant expansion. Study work is being conducted following comprehensive exploration efforts focused on near-mine targets since acquisition. The results will be incorporated in any future expansionary or optimization plans. During the second quarter, approximately 12,700 metres of exploration drilling were completed, primarily on Saúva area targets. ===== SIDA 30 ===== 17 Eagle (USA) Operating Statistics 2023 2022 (100% Basis) YTD Q2 Q1 Total Q4 Q3 Q2 Q1 Ore mined (000s tonnes) 345 189 156 718 165 190 181 182 Ore milled (000s tonnes) 342 181 161 718 170 187 182 179 Grade Nickel (%) 2.8 2.9 2.6 2.8 2.7 2.7 3.0 2.8 Copper (%) 2.1 2.2 2.0 2.3 1.9 2.2 2.5 2.5 Recovery Nickel (%) 88.7 88.8 88.5 86.6 88.6 85.5 87.3 85.3 Copper (%) 97.1 97.0 97.2 97.2 96.8 96.5 97.7 97.6 Production (contained metal) Nickel (tonnes) 8,410 4,686 3,724 17,475 4,096 4,379 4,719 4,281 Copper (tonnes) 7,021 3,881 3,140 15,895 3,081 3,994 4,400 4,420 Revenue ($000s) 174,670 105,250 69,420 520,472 157,060 106,715 106,828 149,869 Production costs ($000s) 91,184 45,735 45,449 193,003 50,581 47,736 55,128 39,558 Gross profit ($000s) 59,665 46,845 12,820 247,946 87,359 37,329 29,796 93,462 Cash cost ($ per pound nickel) 2.11 1.88 2.43 0.79 2.40 1.05 0.90 (1.25) AISC ($ per pound nickel) 4.09 3.34 5.16 3.01 5.23 2.77 2.93 1.19 Gross Profit Gross profit for the quarter ended June 30, 2023 was higher than the prior year quarter, primarily due to positive nickel price adjustments as well as lower depreciation expense. Year-to-date, gross profit was lower than the comparable period in 2022, as a result of lower nickel prices and price adjustments and sales volumes. Production Nickel and copper production in the current quarter and year-to-date were lower than the prior year comparable periods, due to lower grades and throughput. Production of b oth metals is trending higher in the current quarter over the first quarter of 2023 and on a year -to-date basis in accordance with expectations. Both metals are on track to meet full year production guidance. Production Costs and Cash Cost Production costs in the second quarter and year -to-date were lower than the prior year periods due to lower costs for consumables and royalties. Nickel cash cost in the quarter and year -to-date was higher than the prior year periods due to lower sales volumes and lower copper by-products. Annual cash cost guidance has increased from $1.50 - $1.65/lb to $2.30 - $2.45/lb of nickel due mainly to lower by -product credits.

Production Costs and Cash Cost Production costs for the three months ended June 30, 2023, were comparable to the prior year quarter. Year -to-date, production costs were higher than the six months ended June 30, 2022 primarily due to higher zinc sales volumes. Copper cash cost for the three and six months were higher than the prior year comparable periods due to lower copper sales volumes and higher treatment and refining charges and lower zinc by -product credits in the current quarter. Annual copper cash cost guidance remains unchanged . AISC for the three and six months ended June 30, 2023 were higher than the prior year quarter due to higher cash cost and higher sustaining capital expenditures from mine development. ===== SIDA 32 ===== 19 Zinkgruvan (Sweden) Operating Statistics 2023 2022 (100% Basis) YTD Q2 Q1 Total Q4 Q3 Q2 Q1 Ore mined, zinc (000s tonnes) 578 268 310 1,209 325 260 298 326 Ore mined, copper (000s tonnes) 106 51 55 192 48 61 38 45 Ore milled, zinc (000s tonnes) 526 211 315 1,234 309 293 327 305 Ore milled, copper (000s tonnes) 112 34 78 225 26 84 27 88 Grade Zinc (%) 7.1 6.6 7.4 7.0 7.3 6.9 7.3 6.5 Lead (%) 2.7 2.4 2.9 3.0 3.0 2.9 3.3 2.7 Copper (%) 2.6 3.1 2.4 2.1 2.6 2.4 2.3 1.6 Recovery Zinc (%) 87.8 86.3 88.7 88.4 88.3 87.5 89.1 88.7 Lead (%) 80.0 76.2 82.1 82.4 82.2 82.5 83.1 81.7 Copper (%) 88.9 86.1 90.5 87.1 89.0 86.1 87.7 87.3 Production (contained metal) Zinc (tonnes) 32,698 11,938 20,760 76,503 19,785 17,813 21,265 17,640 Lead (tonnes) 11,223 3,816 7,407 30,517 7,619 7,046 9,124 6,728 Copper (tonnes) 2,634 917 1,717 4,077 607 1,737 535 1,198 Silver (000 oz) 1,006 374 632 2,621 663 642 739 577 Revenue ($000s) 90,518 29,520 60,998 292,120 67,178 64,854 70,596 89,492 Production costs ($000s) 46,691 17,786 28,905 115,553 29,590 25,709 29,066 31,188 Gross profit ($000s) 30,827 6,821 24,006 139,828 29,800 33,703 30,500 45,825 Cash cost ($ per pound) 0.43 0.24 0.54 0.32 0.32 0.18 0.44 0.27 AISC ($ per pound) 1.00 1.06 0.97 0.68 0.77 0.50 0.82 0.57 Gross Profit Gross profit for the three and six months ended June 30, 2023, was lower than the prior year periods due to lower net zinc price combined with lower sales volumes. Production Production of zinc and lead in the three and six months ended June 30, 2023 was below the prior year periods, impacted by lower throughput as a result of a shut -down of the mill to perform the planned implementation of the sequential flotation system. In the current quarter, zinc and lead production were also impacted by lower grades and r ecoveries. Copper production in the current quarter and year-to-date was higher than the prior year periods, due to higher grades. Annual zinc and copper production guidance remains unchanged. Production Costs and Cash Cost Production costs for the quarter were lower than the prior year comparable periods due to mainly to lower sales volumes. Year-to-date production costs also benefitted from foreign exchange. Zinc cash cost was lower than the prior year quarter due to lower mine and mill costs. On a year-to-date basis cash cost was higher due to lower sales volumes partially offset by lower production costs and favourable foreign exchange. Full year cash cost guidance has improved from $0.60 - $0.65/lb to $0.45 - $0.50/lb of zinc due to higher by -product credits. AISC for the quarter and year -to-date were higher than the prior year periods due to higher sustaining capital expenditures. ===== SIDA 33 ===== 20 Josemaria Project (Argentina) Project Development The Josemaria Project continues to advance in several areas of pre-construction in reducing risks and enhancing the project, for example by advancing government agreements, evaluating inflation and currency devaluation impacts, enhancing mining and production plans and further water, geotechnical and exploration drilling planned for the remainder of 2023. At Josemaria, the construction of the Phase 1 camp is substantially complete with the exception of the installation of the power supply system and subsequent commissioning of the kitchen. Internal roadwork has also been completed. Site work is now focused on drilling for additional water resources and after the winter in the fourth quarter exploration drilling will commence. The long lead grinding mills started to arrive in Argentina and are scheduled to be moved to San Juan in July with deliveries continuing throughout the remainder of 2023 and into 2024. Negotiation continues on the San Juan infrastructure agreements for the royalty offset funding of the access road and th e power line capital costs with signing of these agreements scheduled after the change in provincial governor determined by the recent July 2nd election. Agreements for the Guandacol access road bypass and road maintenance agreements are nearing completion and work will be proceeding imminently. Additionally, a work plan was prepared for the remainder of 2023 focusing on de -risking the project and adding value to Josemaria as well as advancing project financing and execution readiness activities. This work involves eight work streams in the categories of mine optimization, throughput and concentrator recovery, concentrate shipping, infrastructure optimization, commercial reviews and project financing, execution readiness and project permitting and government agreements. During the current quarter, the Company spent $50.6 million, inclusive of foreign exchange and trading gains on debt and equity investments of $30.7 million (Q2 2022 - $29.1 million). Capital expenditures during the current quarter were $91.7 million (Q2 2022 - $54.9 million). On a year -to-date basis the Company spent $141.1 million in project development costs. Annual capital guidance has been reduced from $400.0 million to $350.0 million to reflect foreign exchange, a delay in planned equipment deliveries and reduced activities. Josemaria Mineral Resources and Mineral Reserves remain unchanged since the 2020 estimates. ===== SIDA 34 ===== 21 Metal Prices, LME Inventories and Smelter Treatment and Refining Charges Overall, the average metal prices for quarter and the year-to-date 2023 were lower than the respective comparative periods with the exception of gold. The average metal prices for copper, zinc and nickel for the second quarter of 2023 were all lower than the average prices for the first quarter of 2023 by; 5% copper, 19% zinc and 14% nickel while the average price for gold for the second quarter of 2023 was 5% higher compared to the first quarter.

During the second quarter of 2023 the treatment charges (“TC”) and refining charges (“RC”) in the spot market for copper concentrates between miners and commodity traders increased from an average spot TC during April of $71 per dmt of concentrate and a sp ot RC of $0.071 per lb of payable copper to a spot TC of $84 per dmt of concentrate and a spot RC of $0.084 per lb of payable copper during June. Also, the spot terms at which Chinese copper smelters were prepared to buy increased through the quarter from a TC of $83 per dmt of concentrate and a RC of $0.083 per payable lb of copper over April to a TC of $91 per dmt of concentrate and a RC of $0.091 per payable lb of copper in June. The terms for annual contracts for copper concentrates for 2023 were reached in December 2022 at a TC of $88 per dmt with a RC of $0.088 per payable lb of copper. The spot TC, delivered China, for zinc concentrates during the second quarter of 2023 decreased from $225 per dmt, flat, in April to $200 per dmt, flat, in June. The 2023 annual terms for zinc concentrates were settled at $274 per dmt of concentrate, with an upscale price escalator of 6% from a price basis of $3,000 per dmt zinc without de-escalator. The Company’s nickel concentrate production from Eagle is sold under several long-term contracts at terms in-line with market conditions. Gold production fro m Chapada and Candelaria is sold at terms in -line with market conditions for copper concentrates. ===== SIDA 35 ===== 22 Liquidity and Capital Resources As at June 30, 2023, the Company had cash and cash equivalents of $190.2 million and a net debt balance of $229.8 million. Cash flow from operations for the three months ended June 30, 2023 amounted to $194.8 million and was $171.6 million lower than the prior year quarter due mainly to a lower comparative change in non -cash working capital, partially offset by lower income tax and higher foreign exchange and trading gains on debt and equity investments. On a year-to-date basis, cash flow from operations was $406.7 million and was $276.9 million lower than the prior year comparable period as a result of lower gross profit before depreciation partially offset by lower income taxes. Cash flow used in investing activities for the three and six months ended June 30, 2023 amounted to $283.5 million and $523.5 million respectively. Cash flow used in investing activities during the current quarter was lower than the prior year quarter due to higher expansionary capex in the current period partially offset by the Josemaria acquisition costs and bridge loan payments. On a year-to-date basis cash flow used in investing activities was comparable to the prior year period. During the current quarter, the Company used $99.9 million for financing activities which was lower than the amount used in the prior year quarter due primarily to the payment of a performance dividend in 2022. On a year -to-date basis, there was cash flow of $119.4 million from financing activities compared to $259.5 million used in the prior year co mparable period. This change was due to higher net proceeds from debt partially offset with lower dividends paid in the current period. Capital Resources The Company continues to expect to be able to fund all its contractual commitments with its operating cash flow, cash on hand and available capital resources. As at June 30, 2023, the Company had $386.5 million of debt and $28.5 million of lease liabilities outstanding. As at June 30, 2023, the Company has a revolving Credit Facility of $1,750.0 million with $176.0 million outstanding (December 31, 2022 - $13.7 million). The Credit Facility bears interest on drawn funds at rates of Term Secured Overnight Financing Rate ("Term SOFR") + Credit Spread Adjustment ("CSA") + 1.45% to Term SOFR + CSA + 2.50% d epending on the Company’s net leverage ratio. The Credit Facility is subject to customary covenants. On April 26, 2023, the Credit Facility was amended extending the term to April 2028 and reducing the CSA to 0.10%. The Company also has equipment financin g with an outstanding balance of $1.2 million as at June 30, 2023 (December 31, 2022 - $2.4 million) and a commercial paper program of $27.2 million (€25.0 million) which matures in May 2025. In June the Company entered into an additional commercial paper program of $54.3 million (€50.0 million) which matures in June 2028. The amounts outstanding related to both commercial paper programs as at June 30, 2023 was $65.2 million (€60.0 million) (December 31, 2022 - $26.7 million). As at June 30, 2023, the Company had outstanding short-term unsecured term loans of $149.1 million (December 31, 2022 - $127.4 million). In July 2023, the Company entered into a third commercial paper program ("Commercial Paper Program 3") which matures in July 2028. The $43.5 millio n (€40.0 million) program bears interest on drawn funds at EURIBOR+0.30%. In July 2023, the Company drew down €30.0 million on Commercial Paper Program 3 and €10.0 million under the second commercial paper program. On July 27, 2023, the Company announced that it had received a new term loan in a principal amount of $800 million, which the Company will use to refinance the drawdown under the Company’s existing $1.750.0 million revolving credit facility which was used to fund the upfront cash consi deration of the Caserones Acquisition. The term loan has a term of three years and provides for an additional $400 million non -committed accordion, which would become available upon receipt of additional binding commitments and closing of up to an addition al nineteen percent (19%) interest in Caserones. The term loan bears interest on US dollar denominated drawn funds at an annual rate equal to Term SOFR+CSA+1.60% to 2.65%, depending on the Company’s net leverage ratio. The term loan is unsecured, save and except for a charge over certain assets in the USA, and has similar covenants to the Company’s existing $1,750.0 million revolving credit facility. ===== SIDA 36 ===== 23 During the three and six months ended June 30, 2023, no shares were purchased under the Company's Normal Course Issuer Bid (Q2 2022 and YTD 2022 - 1,189,200 shares, $8.1 million consideration).

These performance measures have no meaning within generally accepted accounting principles under IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. This data is intended to provide additional i nformation and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The following are non-GAAP measures that the Company uses as key performance indicators. Net Debt Net debt is a performan ce measure used by the Company to assess its financial position. Management believes that in addition to conventional performance measures prepared in accordance with IFRS, net debt is a useful indicator to some investors to evaluate the Company’s financial position. Net debt is defined as cash and cash equivalents, less debt and lease liabilities, excluding deferred financing fees and can be reconciled as follows: ($thousands) June 30, 2023 December 31, 2022 Cash and cash equivalents 190,182 191,387 Current portion of total debt and lease liabilities (284,656) (170,149) Debt and lease liabilities (130,359) (27,179) (415,015) (197,328) Deferred financing fees (netted in above) (4,998) (4,926) (420,013) (202,254) Net debt (229,831) (10,867) Adjusted Operating Cash Flow and Adjusted Operating Cash Flow per Share Adjusted operating cash flow per share is a performance measure used by the Company to assess its ability to generate cash from its operations. Adjusted operating cash flow is defined as cash provided by operating activities, excluding changes in non-cash working capital items. The Company believes adjusted operating cash flow per share is a relevant measure to some investors, as it removes the impact of working capital, which can experience variability period -to-period. Adjusted operating cash flow per share can be reconciled to the Company's cash provided by operating activities as follows: Three months ended June 30, Six months ended June 30, ($thousands, except share and per share amounts) 2023 2022 2023 2022 Cash provided by operating activities 194,844 366,411 406,719 683,668 Changes in non-cash working capital items (84,207) (316,665) (61,015) (161,117) Adjusted operating cash flow 110,637 49,746 345,704 522,551 Basic weighted average number of shares outstanding 772,255,656 766,775,032 771,739,532 751,676,764 Adjusted operating cash flow per share 0.14 0.06 0.45 0.70 Free Cash Flow from Operations and Free Cash Flow The Company believes free cash flow from operations and free cash flow are relevant measures for investors. Free cash flow from operations is indicative of the Company’s ability to generate cash from operations, after consideration of required sustaining capital expenditures necessary to maintain operations. Free cash flow is a relevant measure for some investors, as it is indicative of the Company’s available cash generated. Free cash flow from operations is defined as cash flow provided by operating act ivities, excluding exploration and project investigation costs and less sustaining capital expenditures. Free cash flow is defined as free cash flow from operations les s expansionary capex and exploration and project investigation costs. ===== SIDA 38 ===== 25 The Company has r edefined free cash flow so that it encompasses all capital expenditures, including both sustaining and expansionary, to more fully represent available cash generation.

These measures are presented to provide additional information to investors and other stakeholders on the Company’s underlying operational performance. The Company believes certain investors find this information useful to evaluate the Company’s ability to generate cash flow from the Company’s core operations. Certain items have been excluded from adjusted EBITDA and adjusted earnings such as unrealized foreign exchange and revaluation gains and losses, impairment charges and reversals, gain or loss on debt settlement, interest on tax refunds and assessments, litigations, settlements and other items that do no t represent the Company’s current and on -going operations and are not necessarily indicative of future operating results. Adjusted EBITDA can be reconciled to the Company's Condensed Interim Consolidated Statement of Earnings as follows: Three months ended June 30, Six months ended June 30, ($thousands) 2023 2022 2023 2022 Net earnings (loss) 61,302 (48,626) 226,613 329,483 Add back: Depreciation, depletion and amortization 130,505 142,042 250,752 271,879 Finance income and costs 15,897 17,309 31,596 32,281 Income taxes (19,601) 49,003 29,092 126,209 188,103 159,728 538,053 759,852 Unrealized foreign exchange (19,285) 2,721 (10,641) 10,574 Revaluation gain on derivatives (14,783) (19,593) (34,033) (16,300) Sinkhole costs 11,900 — 16,482 — Revaluation gain on marketable securities (3,464) 1,626 (3,902) (2,266) Gain on disposal of subsidiary — — (5,718) (16,828) Other (283) 4,161 (1,110) 1,385 Total adjustments - EBITDA (25,915) (11,085) (38,922) (23,435) Adjusted EBITDA 162,188 148,643 499,131 736,417 ===== SIDA 39 ===== 26 Adjusted earnings and adjusted EPS can be reconciled to the Company's Condensed Interim Consolidated Statement of Earnings as follows: Three months ended June 30, Six months ended June 30, ($thousands, except share and per share amounts) 2023 2022 2023 2022 Net earnings (loss) attributable to Lundin Mining shareholders 59,109 (52,577) 205,729 292,501 Add back: Total adjustments - EBITDA (25,915) (11,085) (38,922) (23,435) Tax effect on adjustments (554) 5,035 (3,180) 3,001 Deferred tax arising from foreign exchange translation (15,989) 23,091 (21,996) (11,863) Other (634) 260 69 128 Total adjustments (43,092) 17,301 (64,029) (32,169) Adjusted earnings 16,017 (35,276) 141,700 260,332 Basic weighted average number of shares outstanding 772,255,656 766,775,032 771,739,532 751,676,764 Net earnings (loss) attributable to Lundin Mining shareholders 0.08 (0.07) 0.27 0.39 Total adjustments (0.06) 0.02 (0.09) (0.04) Adjusted EPS 0.02 (0.05) 0.18 0.35 Realized Price per Pound Realized price per pound and price per ounce are non-GAAP ratios that are calculated using the non-GAAP financial measures of current period sales and prior period adjustments. Realized prices exclude the effects of the stream cash effects as well as TC/RCs. Management believes that measuring these prices enables investors to better understand performance based on the realized metal sales in the current and prior periods. Capital Expenditures Identifying capital expenditures, on a cash basis, using a sustaining or expansionary classification provides investors with a better understanding of costs required to maintain existing operations, and costs required for future growth of exis ting or new assets. • Sustaining capital expenditures – Expenditures which maintain existing operations and sustain production levels. • Expansionary capital expenditures – Expenditures which increase current or future production capacity, cash flow or earnings potential. Where an expenditure both maintains and expands current operations, classification would be based on the primary decision for which the expenditure is being made. Expansionary capital expenditures are reported excluding capitalized interest and therefore is a non-GAAP measure. Sustaining capital expenditure is a supplementary financial measure. Cash Cost per Pound Copper, zinc and nickel cash costs per pound are key performance measures that management uses to monitor performance. Management uses these statistics to assess how well the Company’s producing mines are performing and to assess overall efficiency and effectiveness of the mining operations. Cash cost is a non-GAAP measure and, although it is calculated according to accepted indust ry practice, the Company’s disclosed cash costs may not be directly comparable to other base metal producers. • Cash cost per pound, gross – Total cash costs directly attributable to mining operations, excluding any allocation of upfront streaming proceeds or capital expenditures for deferred stripping, are divided by the sales volume of the primary metal to arrive at gross cash cost per pound. As this measure is not impacted by fluctuations in sales of by-product metals, it is generally more consistent across periods. ===== SIDA 40 ===== 27 • Cash cost per pound, net of by -products – Credits for by -products sales are deducted from total cash costs directly attributable to mining operations. By-product revenue is adjusted for the terms of streaming agreements, but excludes any deferred revenue from the allocation of upfront cash received. The net cash costs are divided by the sales volume of the primary metal to arrive at net cash cost per pound. The inclusion of by-product credits provides a broader economic measurement, incorporating the benefit of other metals extracted in the production of the primary metal. All-in Sustaining Cost (“AISC”) per Pound AISC per pound is an extension of the cash cost per pound measure discussed above and is also a key performance measure that management uses to monitor performance. Management uses this measure to analyze margins achieved on existing assets while sustaining and maintaining production at current levels. Expansionary capital and certain exploration costs are excluded from this def inition as these are costs typically incurred to extend mine life or materially increase the productive capacity of existing assets, or for new operations. Corporate general and administrative expenses have also been excluded from the all -in sustaining cos t measure, as any attribution of these costs to an operating site would not necessarily be reflective of costs directly attributable to the administration of the site. ===== SIDA 41 ===== 28 Cash and All-in Sustaining Costs can be reconciled to the Company's production costs as follows: Three months ended June 30, 2023 Operations Candelaria Chapada Eagle Neves-Corvo Zinkgruvan ($000s, unless otherwise noted) (Cu) (Cu) (Ni) (Cu) (Zn) Total Sales volumes (Contained metal in concentrate): Tonnes 36,347 10,164 3,859 6,170 9,374 Pounds (000s) 80,132 22,408 8,507 13,603 20,666 Production costs 405,198 Less: Royalties and other (7,969) 397,229 Deduct: By-product credits (122,636) Add: Treatment and refining charges 32,514 Cash cost 171,520 60,351 15,990 54,271 4,975 307,107 Cash cost per pound ($/lb) 2.14 2.69 1.88 3.99 0.24 Add: Sustaining capital expenditure 123,417 19,690 3,562 22,133 15,994 Royalties — 2,029 4,920 83 — Reclamation and other closure accretion and depreciation 2,444 1,847 3,011 1,296 739 Leases and other 3,654 1,171 897 148 100 All-in sustaining cost 301,035 85,088 28,380 77,931 21,808 AISC per pound ($/lb) 3.76 3.80 3.34 5.73 1.06 ($000s, unless otherwise noted) 2023 Guidance Cash cost 620,000 260,000 90,000 180,000 90,000 Cash cost per pound($/lb) 1.80 – 1.95 2.35 – 2.55 2.30 – 2.45 2.10 – 2.30 0.45 – 0.50 Three months ended June 30, 2022 Operations Candelaria Chapada Eagle Neves-Corvo Zinkgruvan ($000s, unless otherwise noted) (Cu) (Cu) (Ni) (Cu) (Zn) Total Sales volumes (Contained metal in concentrate): Tonnes 39,655 7,905 4,206 8,183 18,525 Pounds (000s) 87,424 17,427 9,273 18,040 40,841 Production costs 402,190 Less: Royalties and other (13,657) 388,533 Deduct: By-product credits (134,728) Add: Treatment and refining charges 29,960 Cash cost 162,240 51,872 8,341 43,198 18,114 283,765 Cash cost per pound ($/lb) 1.86 2.98 0.90 2.39 0.44 Add: Sustaining capital expenditure 86,107 29,760 2,923 13,760 14,083 Royalties — 2,442 10,633 (616) — Reclamation and other closure accretion and depreciation 2,082 1,865 4,683 120 956 Leases and other 2,658 1,110 631 194 160 All-in sustaining cost 253,087 87,048 27,211 56,656 33,313 AISC per pound ($/lb) 2.89 5.00 2.93 3.14 0.82 ===== SIDA 42 ===== 29 Six months ended June 30, 2023 Operations Candelaria Chapada Eagle Neves-Corvo Zinkgruvan ($000s, unless otherwise noted) (Cu) (Cu) (Ni) (Cu) (Zn) Total Sales volumes (Contained metal in concentrate): Tonnes 71,917 19,236 6,594 14,201 25,986 Pounds (000s) 158,550 42,408 14,537 31,308 57,289 Production costs 822,962 Less: Royalties and other (20,055) 802,907 Deduct: By-product credits (279,601) Add: Treatment and refining charges 69,129 Cash cost 345,212 107,669 30,630 84,163 24,761 592,435 Cash cost per pound ($/lb) 2.18 2.54 2.11 2.69 0.43 Add: Sustaining capital expenditure 214,103 35,717 10,664 47,194 30,462 Royalties — 4,252 10,606 1,813 — Reclamation and other closure accretion and depreciation 4,751 3,648 5,969 2,620 1,800 Leases and other 6,797 2,137 1,644 306 202 All-in sustaining cost 570,863 153,423 59,513 136,096 57,225 AISC per pound ($/lb) 3.60 3.62 4.09 4.35 1.00 Six months ended June 30, 2022 Operations Candelaria Chapada Eagle Neves-Corvo Zinkgruvan ($000s, unless otherwise noted) (Cu) (Cu) (Ni) (Cu) (Zn) Total Sales volumes (Contained metal in concentrate): Tonnes 78,103 20,709 7,473 16,667 34,327 Pounds (000s) 172,187 45,655 16,475 36,744 75,678 Production costs 784,617 Less: Royalties and other (29,528) 755,089 Deduct: By-product credits (315,735) Add: Treatment and refining charges 62,115 Cash cost 296,225 103,309 (638) 75,001 27,572 501,469 Cash cost per pound ($/lb) 1.72 2.26 (0.04) 2.04 0.36 Add: Sustaining capital expenditure 169,071 44,215 7,383 33,276 23,122 Royalties — 6,106 18,424 2,197 — Reclamation and other closure accretion and depreciation 4,051 3,749 9,300 451 2,073 Leases and other 4,626 2,039 1,282 396 398 All-in sustaining cost 473,973 159,417 35,751 111,321 53,165 AISC per pound ($/lb) 2.75 3.49 2.17 3.03 0.70 ===== SIDA 43 ===== 30 Managing Risks Risks and Uncertainties The Company’s business activities are subject to a variety and wide range of inherent risks and uncertainties.

Tabular amounts in thousands of US dollars, except for shares and per share amounts) - 6 - 1. NATURE OF OPERATIONS Lundin Mining Corporation is a diversified Canadian base metals mining company primarily producing copper, zinc, gold and nickel. The Company owns 80% of the Candelaria and Ojos del Salado mining complex ("Candelaria") located in Chile. The Company’s wholly -owned operating assets include the Chapada mine located in Brazil, the Eagle mine located in the United States of America (“USA”), the Neves -Corvo mine loca ted in Portugal, and the Zinkgruvan mine located in Sweden. In addition, the Company owns the large scale copper -gold Josemaria project ("Josemaria Project"), located in Argentina. On July 13, 2023, the Company announced the closing of the acquisition of a fifty-one percent (51%) controlling interest in the Caserones copper-molybdenum mine ("Caserones") located in Chile (Note 23). The Company’s common shares are listed on the Toronto Stock Exchange (“TSX”) in Canada and the Nasdaq Stockholm Exchange in Sweden. The Company is incorporated under the Canada Business Corporations Act. The Company is domiciled in Canada and its registered address is 150 King Street West, Toronto, Ontario, Canada. 2. BASIS OF PRESENTATION AND SUMMARY OF MATERIAL ACCOUNTING POLICIES (i) Basis of presentation and measurement The unaudited condensed interim consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and Interpretations of the Inter national Financial Reporting Interpretations Committee which the Canadian Accounting Standards Board has approved for incorporation into Part 1 of the CPA Canada Handbook - Accounting including IAS 34 Interim Financial Reporting. The condensed interim consolidated financial statements should be read in conjunction with the annual consolidated financial statements for the year ended December 31, 2022. The consolidated financial statements have been prepared on a historical cost basis except for certain financial instruments which have been measured at fair value. The Company's presentation currency is United States (“US”) dollars. Reference herein to $ or USD is to US dollars, C$ or CAD is to Canadian dollars, SEK is to Swedish krona, € refers to the Euro, CLP refers to the Chilean peso, BRL refers to the Brazilian real, and ARS refers to the Argentine peso. Balance sheet items are classified as current if receipt or payment is due within twelve months. Otherwise, they are presented as non-current. These condensed interim consolidated financial statements were approved by the Board of Directors for issue on August 2, 2023. (ii) Material accounting policies The accounting policies followed in these condensed interim consolidated financial statem ents are consistent with those disclosed in Note 2 of the Company’s consolidated financial statements for the year ended December 31, 2022, except as discussed below. (iii) New standards and interpretations adopted In May 2021, the IASB issued amendments to IAS 12, Income Taxes.
