Coeur Reports Third Quarter 2021 Results

Reaffirms Production Guidance; Updates Cost and Capital Expenditure Guidance

Coeur Mining, Inc. ("Coeur" or the "Company") (NYSE: CDE) today reported third quarter 2021 financial results, including revenue of $208.0 million and cash flow from operating activities of $21.8 million. The Company reported GAAP net loss from continuing operations of $54.8 million, or $0.21 per share, which included a $26.0 million non-cash write-down of Mexican value-added tax ("VAT") refunds and non-cash unrealized losses of $35.7 million on strategic equity investments, primarily related to Coeur's 18% equity ownership of Victoria Gold Corp. ("Victoria") during the quarter. On an adjusted basis¹, Coeur reported EBITDA of $48.8 million, cash flow from operating activities before changes in working capital of $34.8 million and net loss from continuing operations of $2.6 million, or $0.01 per share.

Key Highlights

• Solid production results and stronger fourth quarter expected to result in full-year production levels within 2021 guidance ranges - Third quarter gold and silver production totaled 87,083 and 2.5 million ounces, respectively. Production levels are expected to increase during the fourth quarter and finish the year within the Company's guidance range of 322,500 - 367,500 ounces of gold and 9.7 - 12.2 million ounces of silver
• Second consecutive quarterly exploration record - Coeur achieved another quarterly exploration record by investing approximately $20.0 million and drilling roughly 326,500 feet (99,500 meters) from up to 27 drill rigs at six locations. The Company continues to generate meaningful new discoveries and identify future growth opportunities from the largest exploration program in its history
• Strong quarterly results at Wharf - Wharf's gold production increased 17% quarter-over-quarter to 28,157 ounces, leading to $24.9 million and $23.9 million of operating and free cash flow¹, respectively - the second highest quarterly cash flow figures since Coeur's acquisition of the operation in early 2015. Cumulative operating and free cash flow¹ since the acquisition for approximately $99.5 million now totals $319.6 million and $290.7 million, respectively, implying a current internal rate of return of approximately 43%
• Rochester expansion now 42% complete; seeking to mitigate inflationary pressures on remaining unawarded work packages - Coeur achieved several key milestones at its Rochester expansion project during the quarter while also continuing to incorporate learnings from ongoing test work and operating activities to maximize future operating flexibility and de-risk the expansion. The Company currently estimates a likely 10% - 15% increase in the project's overall total capital estimate due to the impact of inflationary pressures on the four remaining unawarded packages
• Re-adjusting timing and scale of Silvertip expansion due to exploration success and current inflationary environment - The Company has elected to assess the potential for a larger-scale expansion of Silvertip given ongoing exploration success and the potential benefits of a larger-scale operation. Additionally, recently-received preliminary capital estimates targeting a smaller, accelerated expansion and re-start were higher than anticipated, reflecting current inflationary pressures, supply and labor disruptions, and schedule constraints. A potentially larger-scale expansion and restart is expected to follow the completion of the ongoing Rochester expansion project
• Strategic sale of La Preciosa silver project to Avino Silver & Gold - Coeur has entered into a definitive agreement (the "Agreement") with Avino Silver & Gold Mines Ltd. ("Avino") (TSX/NYSE American: ASM) to sell its La Preciosa silver project, which is located near Avino's existing operation in the State of Durango, Mexico for fixed consideration of approximately $34.7 million and contingent consideration of up to an additional $58.8 million for total potential consideration of up to $93.4 million plus two royalties that collectively cover the entire La Preciosa land package. The combination of equity ownership, contingent payments and royalties provides exposure to future upside potential
• Maintaining balance sheet flexibility to support ongoing investments - The Company ended the third quarter with total liquidity of approximately $330.0 million, including $85.0 million of cash and $245.0 million of available capacity under its $300.0 million revolving credit facility ("RCF")²

"Our third quarter results reflect our strategy of elevated near-term investment in our balanced platform of North American assets to generate attractive returns and long-term, sustainable free cash flow¹, from lower cost, longer life precious metals assets," said Mitchell J. Krebs, President and Chief Executive Officer. "During the quarter, Wharf was our standout performer by delivering its second-highest quarterly cash flow figures since we acquired it in early 2015. Additionally, Wharf recently celebrated one year without a recordable safety incident. Mr. Krebs continued, "With a strong expected fourth quarter underway, we remain on track to achieve our 2021 production guidance at each of our operations."

"Our sector-leading level of investment in exploration continues to focus on delivering resource and reserve growth to further extend mine lives and generate new potential growth opportunities. Our key near-term catalyst remains the Plan of Operations Amendment 11 (`POA 11') expansion at Rochester in northern Nevada, where we continue to generate and apply key learnings from the existing operation to best position the expanded operation for long-term success once construction is completed. Despite the current inflationary environment, we believe Rochester remains a transformative, well-funded source of growth for the Company on which we remain laser focused."

"Preliminary capital estimates to expand and restart the Silvertip operation in northern British Columbia were received during the quarter and came in higher than we anticipated, reflecting the current inflationary environment, supply and labor disruptions, and schedule constraints. However, the extent of our ongoing exploration success and commitment to our capital allocation framework is leading us to investigate the possibility of a larger expansion and restart to take advantage of a potentially much larger resource than we had originally contemplated when we acquired the high-grade Silvertip mine. Although this will require additional time to assess while we carry out further drilling, it will have the benefits of allowing us to prioritize a successful completion of the Rochester expansion, preserving balance sheet flexibility and potentially allowing for many of these macroeconomic factors to stabilize."

"Finally, we have signed an agreement to sell the La Preciosa project in Mexico to Avino, which operates the nearby Avino mine. We believe this transaction will accelerate value creation from this asset by allowing the Avino team to incorporate La Preciosa into its nearby Avino operation. Moreover, this transaction is consistent with our capital allocation framework and allows us to prioritize higher-return growth from our U.S. and Canadian exploration and development projects while retaining upside to La Preciosa through equity participation, the retention of royalties and contingent payments," concluded Mr. Krebs.

Financial and Operating Highlights (Unaudited)

Financial Results

Third quarter 2021 revenue totaled $208.0 million compared to $214.9 million in the prior period and $229.7 million in the third quarter of 2020. The Company produced 87,083 and 2.5 million ounces of gold and silver, respectively, during the quarter. Metal sales totaled 89,804 ounces of gold and 2.5 million ounces of silver. Average realized gold and silver prices for the quarter were $1,645 and $24.18 per ounce, respectively, compared to $1,651 and $26.60 per ounce in the prior period and $1,754 and $24.15 per ounce in the third quarter of 2020.

Gold and silver sales accounted for 71% and 29% of quarterly revenue, respectively. The Company's U.S. operations accounted for approximately 64% of third quarter revenue.

Costs applicable to sales³ remained relatively consistent quarter-over-quarter at $134.3 million. General and administrative expenses for the quarter totaled $8.7 million compared to $10.5 million in the prior period, primarily due to lower employee-related costs.

Coeur invested approximately $20.0 million ($15.4 million expensed and $4.6 million capitalized) in exploration during the quarter, compared to roughly $18.6 million ($12.4 million expensed and $6.2 million capitalized) in the prior period, reflecting an increase in drilling activity at Kensington, Rochester and Silvertip. Notably, the Company completed approximately 326,500 feet (99,500 meters) of expansion and infill drilling during the period, establishing another new Company record. See the "Operations" and "Exploration" sections for additional detail on the Company's exploration activities.

Operating costs related to COVID-19 mitigation and response efforts declined to $0.6 million during the third quarter, compared to $2.3 million in the prior period and $4.0 million in the third quarter of 2020. These costs were primarily driven by employee-related expenses at Kensington and Palmarejo, and are included in "Pre-development, reclamation, and other expenses" on the Company's income statement. Coeur has maintained rigorous health and safety protocols across its operations and in surrounding communities aimed at limiting the exposure and transmission of COVID-19 which has led to minimal business interruptions.

The Company recorded an income tax expense of $6.4 million during the third quarter. Cash income and mining taxes paid during the period totaled approximately $8.0 million.

Quarterly operating cash flow totaled $21.8 million compared to $58.1 million in the prior period, largely driven by lower metal sales and changes in working capital. Changes in working capital during the quarter were $(13.0) million, compared to $26.6 million in the prior period, largely due to the buildup of leach pad inventory at Rochester, timing of interest payments as well as a cash outflow of $7.4 million associated with Coeur's prepayment agreement at Kensington. The Company expects the remaining $7.6 million cash outflow under the arrangement to occur in the fourth quarter.

Capital expenditures during the third quarter were $71.3 million compared to $78.2 million in the prior period. Expenditures related to the POA 11 expansion project at Rochester totaled $39.0 million during the quarter, compared to $33.2 million in the second quarter. Sustaining and development capital expenditures accounted for approximately 26% and 74%, respectively, of the Company's total capital investment during the quarter.

Capital Projects Update

Rochester Expansion

Overall progress under the current scope of the project was approximately 42% complete at the end of the period. During the third quarter, the Company completed crushing of over-liner material for the new Stage VI leach pad and commenced foundation work for the Merrill-Crowe process plant and crusher corridor.

As of September 30, 2021, the Company has committed approximately $351 million of capital since the inception of the expansion project in the third quarter of 2020, including 78 executed contracts valued at approximately $339 million. There are a total of four packages yet to be awarded, including two structural, mechanical, piping, electrical and instrumentation ("SMPEI") construction contracts for the Merrill-Crowe process plant and crushing circuit, respectively.

As previously disclosed, Coeur began experiencing signs of inflationary pressures on recent bids received for the remaining uncommitted contracts. The Company is in the process of reassessing its options to mitigate these pressures by (i) re-scoping and combining these remaining contracts to capture potential cost savings and efficiencies, and (ii) modifying its commercial approach to awarding the remaining uncommitted contracts.

Coeur currently estimates that the overall impact of inflationary pressures, including the two SMPEI contracts, could potentially add up to 10% - 15% to the total construction capital estimate for the expansion project. The total construction capital estimate for POA 11 of approximately $453 million, as previously disclosed, includes $35 million of 2020 budgeted expenditures, $397 million as reflected in Coeur's Canadian National Instrument 43-101 Technical Report for Rochester dated December 16, 2020 and roughly $20 million of project enhancements reported in the second quarter of 2021.

Coeur has been using Rochester's existing crusher system and the Stage IV leach pad as a full-scale test bed to optimize performance and further de-risk the POA 11 expansion project.

Through these efforts, the Company has identified a potential opportunity to enhance future operating flexibility by incorporating pre-screens into the flowsheet for the newly constructed crushing circuit. While the Company completes detailed engineering related to implementing pre-screens into the POA 11 expansion in the coming months, Coeur intends to install pre-screens on the existing crusher system during the first half of 2022, which is expected to improve the performance of the existing crushing system and Stage IV leach pad while providing additional experience and knowledge that can potentially be applied to the new crusher corridor as part of the POA 11 expansion. If the Company determines that pre-screens are a value-accretive scope change to the project, Coeur currently estimates that commissioning and ramp-up of the new crushing circuit could be extended by three to six months.

Silvertip Expansion and Restart

During the quarter, the Company received preliminary capital estimates for an accelerated expansion and restart, which were higher than originally anticipated and reflect overall inflationary pressures as well as supply disruptions and labor market tightness consistent with broader macroeconomic themes.

Coeur continues to generate positive results from its ongoing exploration program at Silvertip. Assay results continue to demonstrate the potential for significant resource growth with over two miles (3.5 kilometers) of north-south strike length now delineated, more than triple the original resource strike length. As highlighted in the Company's news release published on September 9, 2021, recent drilling has encountered flat-lying, manto-style mineralization with meaningful thicknesses that connects to the vertical massive sulfide feeder structures in both the Southern Silver and Discovery South zones, demonstrating the potential to grow resource tonnage with additional drilling. Recent drilling south of the Southern Silver zone has cut 11 horizontal manto-style massive sulfide horizons with greater than 10% sphalerite, further suggesting the mineral system may grow to the south. Additionally, ongoing metallurgical test work is validating the Company's assumptions on potential recovery rates and concentrate qualities.

Given these drilling results, the enhanced understanding of the Silvertip deposit and the potential to significantly expand the size of the resource with continued drilling, Coeur is now assessing the opportunity to significantly enhance the economics of a potential expansion and restart by re-evaluating the overall scope, including higher throughput, staging options, delivery timeline and commercial approach to the project.

Coeur anticipates this ongoing review, current macroeconomic conditions impacting capital estimates and continued exploration investment will result in the Company sequencing a potential Silvertip expansion and restart following the completion of the POA 11 expansion at Rochester. Coeur believes the benefits of this sequencing includes (i) allowing for an acute focus on successful completion of the Rochester expansion, and (ii) maximizing balance sheet flexibility.

Liquidity Update

The Company ended the third quarter with total liquidity of approximately $330.0 million, including $85.0 million of cash and $245.0 million of available capacity under its $300.0 million RCF². The aggregate borrowing capacity under the RCF may be increased by up to $100.0 million. Additionally, the Company had $139.7 million of strategic investments in equity securities and the full $100.0 million available under its at-the-market common stock offering program established in April 2020 ("ATM Program").

Hedging Update

The Company did not execute any additional hedges during the third quarter. Coeur previously completed its gold hedging program for 2021 and continues to proactively monitor market conditions to potentially layer in additional hedges on up to 50% of expected gold production in 2022. The Company's silver price exposure remains unhedged. An overview of the hedges currently implemented is outlined below:

Mexican VAT

Under the legacy royalty agreement between Coeur's Mexican subsidiary (Coeur Mexicana, S.A. de C.V., or "Coeur Mexicana") and a subsidiary of Franco-Nevada Corporation that was terminated in 2016, the Company was entitled to receive refunds of VAT paid on each royalty payment from the tax administration in Mexico - Servicio de Administración Tributaria ("SAT").

Coeur applied for and initially received VAT refunds; however, in 2011 SAT began denying the Company's VAT refund requests based on the argument that VAT was not legally due on the royalty payments. Accordingly, Coeur began to request refunds of the VAT as undue payments, which SAT also denied. The Company has since been engaged in ongoing efforts to recover the VAT from the Mexican government (including through litigation and potential arbitration as well as refiling VAT refund requests).

While the Company believes that it remains legally entitled to be refunded the full amount of the VAT receivable, based on the continued failure to recover the VAT receivable from the Mexican government and recent unfavorable Mexican court decisions which the Company and its counsel believes are contrary to legal precedent, conflicting and erroneous, Coeur wrote off the $26.0 million carrying value of the VAT receivable as of September 30, 2021. Notwithstanding the write-down, the Company intends to continue vigorously pursuing the VAT refunds, including potentially pursuing arbitration under the North American Free Trade Agreement.

Gold sales under Coeur Mexicana's current stream agreement with a subsidiary of Franco-Nevada Corporation, which took effect upon termination of the legacy royalty agreement in 2016, are not subject to VAT.

Mark-to-Market Adjustments

The Company values its strategic investments in equity securities as of the end of each reporting period. The estimated fair values of the Company's equity investments in Victoria and Integra Resources Corp. were $131.2 million and $8.5 million, respectively, at September 30, 2021 compared to $164.7 million and $9.6 million, respectively, at June 30, 2021, resulting in a non-cash unrealized loss of $35.7 million during the third quarter of 2021. This figure is included in "Fair value adjustments, net" on the Company's income statement.

Rochester LCM Adjustment

Coeur reports the carrying value of metal and leach pad inventory at the lower of cost or net realizable value, with cost being determined using a weighted average cost method. At the end of the third quarter, the cost of ore on leach pads at Rochester exceeded its net realizable value which resulted in an lower of cost or market ("LCM") adjustment of $6.0 million (approximately $5.3 million in costs applicable to sales³ and $0.7 million of amortization).

La Preciosa Transaction

Under the Agreement entered into on October 27, 2021, Coeur is selling its La Preciosa project located in the State of Durango, Mexico to Avino. The transaction consideration includes:

• Total fixed proceeds of $34.7 million, including:
  • (i) $15.0 million upon closing of the transaction,
  • (ii) $5.0 million promissory note that matures prior to the first anniversary of the transaction closing, and
  • (iii) Equity consideration of 14.0 million units, payable on closing, each consisting of one share of Avino common stock and one half of one common share purchase warrant of Avino common stock, priced at a 25% premium to the 20-day volume weighted average price prior to announcement. Coeur is expected to hold 12% and 16% of the basic and fully diluted shares outstanding of Avino upon closing of the transaction. The initial value of the equity consideration using the closing price of Avino from the day prior to announcement is approximately $14.7 million
• Total contingent consideration of up to $58.8 million, including:
  • (i) deferred cash consideration of approximately $8.8 million to be paid no later than the first anniversary of initial production from any portion of the La Preciosa project, and
  • (ii) contingent payments of $0.25 per silver equivalent ounce (subject to an inflationary adjustment) on any new mineral reserves discovered and declared outside of the current resource area at the La Preciosa project, up to a maximum payment of $50.0 million
• Two royalties covering the La Preciosa land package, including (i) a 1.25% net smelter returns royalty on properties covering the Gloria and Abundancia areas of the La Preciosa project and (ii) a 2.00% gross value royalty on all areas of the La Preciosa project other than the Gloria and Abundancia areas, offset by the amount of any new mineral reserve contingent payments made to Coeur

In connection with the transaction, Coeur and Avino will enter into a governance agreement on closing pursuant to which, among other rights, Coeur will be granted preemptive rights to maintain its pro rata interest in Avino and the right to appoint one director to Avino's Board of Directors or a board observer so long as Coeur maintains a minimum ownership of 10% in Avino. The transaction is subject to customary closing conditions, including required regulatory approvals and is expected to close in the first quarter of 2022.

Operations

Third quarter 2021 highlights for each of the Company's operations are provided below.

Palmarejo, Mexico

Operational

• Third quarter gold and silver production totaled 24,254 and 1.7 million ounces, respectively, compared to 27,595 and 1.7 million ounces in the prior period and 29,296 and 1.8 million ounces in the third quarter of 2020
• Production during the quarter continued to benefit from higher mill throughput and increased recoveries, offset by lower average gold and silver grades due to the processing of additional development ore. Higher recoveries in the quarter reflect ongoing blending optimization and business improvement initiatives as well as a drawdown of in-circuit inventory
• The Company continues to accelerate development and rehabilitation rates in active areas of the mine, advancing development in future expansion areas to maintain header options and flexibility to maintain its focus on driving higher production rates while prioritizing the health and safety of its workforce

Financial

• Third quarter adjusted CAS¹ for gold and silver on a co-product basis totaled $704 and $12.50 per ounce, respectively, compared to $662 and $13.34 per ounce in the prior period, reflecting the combination of metal sales and average realized prices which impacts the allocation of costs on a co-product basis, lower average grades as well as higher cement consumption related to ongoing rehabilitation efforts
• Capital expenditures in the third quarter were $8.5 million compared to $9.8 million in the second quarter, reflecting slightly lower investment in business improvement projects, underground development and infill drilling
• Free cash flow¹ in the third quarter totaled $14.7 million compared to $23.6 million in the prior period, largely driven by lower gold sales quarter-over-quarter

Exploration

• Exploration investment for the third quarter totaled approximately $4.2 million ($2.8 million expensed and $1.4 million capitalized), compared to roughly $3.6 million ($1.8 million expensed and $1.8 million capitalized) in the prior period
• Up to eight surface and underground core rigs were active during the quarter. A total of approximately 65,000 feet (19,800 meters) were drilled during the period, including 38,400 feet (11,700 meters) of expansion and 26,600 feet (8,100 meters) of infill drilling
• Infill drilling focused on specific zones within the Independencia and Guadalupe deposits. Surface rigs targeted areas of the Northwest Independencia, Hidalgo (located within the Independencia deposit) and La Patria (located within the Guadalupe deposit) zones, while underground rigs focused on closing off extensions of the southern portion of the Independencia zone
• Expansion drilling during the quarter continued to focus on the Hidalgo and El Ojito (located in the northeastern portion of the Independencia deposit) zones
• Expansion and greenfield target generation was focused mainly in the Guazapares district (east of the Palmarejo district and outside of the gold stream area of influence). Coeur is currently in the process of obtaining surface agreements and environmental permits for the La Carmela target (located within the Guazapares district) and anticipates drilling this area by the end of the year
• Coeur plans for eight drill rigs to be active at Palmarejo in the fourth quarter and expects to maintain this pace throughout 2022

Other

• Approximately 47% (11,701 ounces) of Palmarejo's gold sales in the third quarter were sold under its gold stream agreement at a price of $800 per ounce. The Company anticipates approximately 40% - 45% of Palmarejo's gold sales for 2021 will be sold under the stream agreement

Guidance

• Full-year 2021 production guidance remains unchanged at 100,000 - 110,000 ounces of gold and 6.5 - 7.8 million ounces of silver
• CAS¹ guidance remains unchanged at $635 - $735 per gold ounce and $11.75 - $12.75 per silver ounce
• Capital expenditures are expected to be slightly lower at approximately $35 - $40 million (previously $40 - $45 million)

Rochester, Nevada

Operational

• Silver and gold production in the third quarter totaled 0.7 million and 6,051 ounces, respectively, compared to 0.9 million and 7,232 ounces in the prior period and 0.7 million and 6,462 ounces in the third quarter of 2020
• Tons placed increased 7% quarter-over-quarter to 3.4 million, largely due to operational improvements since successfully swapping out the secondary crushing unit in April 2021. This helped Coeur crush just under 1.3 million tons of over-liner material for the Stage VI leach pad across 38.5 days during the period, completing the nearly 1.8 million tons necessary for the POA 11 expansion project
• Silver production during the quarter was affected primarily by the crushing of over-liner material which impacted the Company's ability to stack and leach material on the Stage IV leach pad, while gold production largely reflects a 56% decrease in run-of-mine material placed quarter-over-quarter due to lower allocated haul truck hours
• The execution of key projects has impacted Coeur's ability to place material on the Stage IV leach pad over approximately 72 days since the beginning of the year, including (i) 54 days for the crushing of over-liner material and (ii) 18 days for the swap-out of the secondary crushing unit

Financial

• Third quarter adjusted CAS¹ figures in the table above and highlighted below exclude the impact of an LCM adjustment totaling approximately $5.3 million related to the net realizable value of metal and leach pad inventory. Second quarter adjusted CAS¹ figures in the table above and highlighted below include a non-cash inventory charge of approximately $8.6 million related to a change in Coeur's recovery rate assumption on the Stage IV leach pad
• Third quarter adjusted CAS¹ for silver and gold on a co-product basis totaled $22.68 and $1,665 per ounce, respectively, compared to $26.09 and $1,787 per ounce in the prior period, largely driven by lower metal sales and the inclusion of a non-cash inventory charge taken in the prior period
• Capital expenditures decreased slightly quarter-over-quarter to $40.1 million, reflecting continued investment in the POA 11 expansion project and the completion of several sustaining projects in the prior period
• Free cash flow¹ in the third quarter totaled $(49.6) million compared to $(38.3) million in the prior period

Exploration

• Quarterly exploration investment totaled approximately $3.5 million ($2.4 million expensed and $1.1 million capitalized), compared to roughly $2.0 million ($0.9 million expensed and $1.1 million capitalized) in the prior period
• Two reverse circulation rigs and two core rigs were active during the quarter. Expansion drilling tested Nevada Packard, North and East Rochester, and Lincoln Hill, while infill drilling focused within the Rochester pit. A total of approximately 40,400 feet (12,300 meters) were drilled during the period, including 30,100 feet (9,175 meters) focused on expansion and 10,300 feet (3,125 meters) focused on infill drilling
• Coeur plans to have four drill rigs active at Rochester for the remainder of the year. One core and two reverse circulation rigs are expected to focus on expansion targets at North Rochester and Plainview (located north of North Rochester)
• Additionally, the Company expects to move one core and one reverse circulation rig to begin infill drilling at Lincoln Hill and scout drilling at Gold Ridge during the fourth quarter, respectively
• An aggressive district-wide greenfield, gold-focused exploration program began in the third quarter and is scheduled to continue into the fourth quarter, consisting of soil geochemistry and ground geophysical work as well as the drilling mentioned above. The geochemistry and geophysical surveys are expected to cover Lincoln Hill, Independence Hill and Gold Ridge as well as areas west of Rochester and northwest of Nevada Packard. The combined data from this program, when integrated with historic data over the area, is expected to identify new targets for drilling in 2022 and beyond

Guidance

• Full-year 2021 production guidance remains unchanged at 3.2 - 4.4 million ounces of silver and 22,500 - 32,500 ounces of gold
• CAS¹ in 2021 are expected to be slightly higher at $21.00 - $23.00 per silver ounce (previously $20.00 - $22.00 per ounce) and $1,450 - $1,550 per gold ounce (previously $1,350 - $1,500 per ounce)
• Capital expenditures are expected to be slightly lower at approximately $158 - $170 million (previously $155 - $200 million)

Kensington, Alaska

Operational

• Gold production in the third quarter totaled 28,621 ounces compared to 28,322 ounces in the prior period and 26,797 ounces in the third quarter of 2020
• Consistent quarter-over-quarter production was driven by slightly higher average gold grade, partially offset by lower mill throughput driven by the availability of spare parts for stope drills in the Kensington Main deposit
• Jualin accounted for approximately 13% of Kensington's third quarter production, lower than the prior period of roughly 20%, largely due to stope sequencing

Financial

• Third quarter adjusted CAS¹ totaled $1,150 per ounce compared to $1,088 per ounce in the prior period, reflecting increased employee-related expenses as well as higher maintenance and consumable costs, partially offset by additional gold ounces sold
• Capital expenditures remained relatively consistent quarter-over-quarter at $6.3 million, primarily due to slightly higher underground development and additional infill drilling
• Free cash flow¹ in the third quarter totaled $7.3 million, including cash outflow of approximately $7.4 million associated with the Company's prepayment agreement at Kensington. Excluding the effect of the prepayment, free cash flow¹ totaled approximately $14.7 million in the third quarter

Exploration

• Exploration investment in the quarter totaled approximately $4.1 million ($2.7 million expensed and $1.4 million capitalized), compared to $1.9 million ($1.3 million expensed and $0.6 million capitalized) in the prior period
• Three underground and two surface core rigs were active during the quarter. A total of approximately 54,500 feet (16,625 meters) were drilled during the period, including 29,800 feet (9,100 meters) of expansion and 24,700 feet (7,525 meters) of infill drilling
• Three underground rigs focused on infill drilling at Elmira and upper Kensington Zone 30 as well as expansion drilling at Elmira, Johnson, Jualin and Raven. Additionally, two surface core rigs completed scout drilling late in the period at the Big Lake, Gold King and Comet targets
• For the fourth quarter, three underground drill rigs are expected to focus on (i) infill and expansion drilling at Elmira, (ii) infill drilling at upper Kensington Zone 30, and (iii) expansion drilling at Johnson, upper Raven and Jennifer. One surface rig is also scheduled to begin road-access scout drilling on the Valentine-Fremming target

Guidance

• Production guidance in 2021 remains unchanged at 115,000 - 130,000 ounces of gold
• CAS¹ in 2021 remains unchanged at $1,010 - $1,110 per gold ounce
• Capital expenditures are expected to be slightly lower at approximately $21 - $25 million (previously $23 - $30 million)

Wharf, South Dakota

Operational

• Gold production increased 17% quarter-over-quarter to 28,157 ounces, largely driven by a significant improvement in placement rates and the stacking of higher average grade material earlier in the year. Year-over-year gold production decreased 16% as the third quarter of 2020 was the highest quarterly production at Wharf since Coeur's acquisition
• Higher placement rates during the quarter were driven by favorable crusher conditions as well as efficiencies gained through improved maintenance and operating strategies

Financial

• Adjusted CAS¹ on a by-product basis remained relatively consistent quarter-over-quarter at $971 per ounce
• Capital expenditures decreased slightly quarter-over-quarter to $1.0 million, reflecting a lower investment in infill drilling during the period
• Free cash flow¹ was $23.9 million in the third quarter compared to $15.9 million in the prior period, largely driven by increased metal sales

Exploration

• Exploration investment in the quarter totaled approximately $0.8 million (substantially all capitalized), compared to $1.2 million (substantially all capitalized) in the prior period
• A total of approximately 21,400 feet (6,500 meters) were drilled during the period using one reverse circulation rig, focusing on infill targets at the Portland Ridge - Boston claim group (located on the southern edge of the operation), Flossie (located west of Portland Ridge), Sunshine (near Flossie) and Juno (located north of the Portland pit) areas
• Following the successful summer drilling season, Coeur plans to continue drilling with one reverse circulation rig through the rest of 2021 and into 2022 in the Flossie, eastern Portland Ridge and Juno areas
• After more than two years of data review and drilling, the Company has made the decision not to proceed with its option agreement to acquire the Richmond Hill project (located approximately four miles north-northeast of Wharf)

Guidance

• Gold production in 2021 remains unchanged at 85,000 - 95,000 ounces
• CAS¹ in 2021 remains unchanged at $960 - $1,060 per gold ounce
• Capital expenditures are expected to be approximately $5 - $8 million

Silvertip, British Columbia

• Mining and processing activities were temporarily suspended at Silvertip on February 19, 2020 (unrelated to COVID-19)

Operational

• The Company continues to generate positive results from ongoing exploration and confirmatory metallurgical test work. Additionally, Coeur is currently evaluating various opportunities to enhance the economics of a potential expansion and restart of Silvertip
• Coeur plans to publish an updated mine plan and economic analysis for Silvertip once it determines an optimized path forward for the project which may result in a larger, more attractive operation

• Ongoing carrying costs in the third quarter were $5.6 million, compared to $6.4 million in the prior period
• Capital expenditures during the third quarter totaled $15.1 million compared to $18.5 million in the prior period, largely due to efficiencies in executing early works projects and a transition to focus more on expansion drilling. Mill decontamination remains within budget and on schedule for completion during the fourth quarter of 2021

Exploration

• Exploration investment in the third quarter totaled approximately $4.6 million (substantially all expensed), compared to roughly $5.2 million ($3.6 million expensed and $1.6 million capitalized) in the prior period
• Up to six core rigs were active during the quarter (four on surface and two underground) focused on expansion drilling at southern portions and deeper extensions of the Southern Silver, Discovery and Camp Creek zones. A total of approximately 95,000 feet (28,950 meters) were drilled during the period
• For the remainder of the year, underground drilling is scheduled to continue focusing on expansion drilling at the Southern Silver and Discovery South zones. Surface drilling is expected to move to lower elevation platforms and focus on the northern extensions of the Camp Creek and Discovery zones

Guidance

• Capital expenditures for 2021 are now expected to total $59 - $65 million (previously $75 - $90 million). Early works have progressed ahead of schedule and are expected to be completed for less than anticipated, which partially reflects the Company's plan to prioritize a potentially larger expansion to enhance the economics of a potential expansion and restart

Exploration

During the third quarter, the Company drilled a record of roughly 326,500 feet (99,500 meters) at a total investment of approximately $20.0 million ($15.4 million expensed and $4.6 million capitalized), compared to roughly 320,400 feet (97,675 meters) at a total investment of approximately $18.6 million ($12.4 million expensed and $6.2 million capitalized) in the prior period. The increase in exploration activity was largely driven by a ramp-up of drilling at Kensington, Rochester and Silvertip as well as the continuation of expansion and infill programs across the rest of the Company's portfolio.

Three reverse circulation drill rigs were active at the Crown exploration property in southern Nevada during the quarter, primarily focused on the Daisy, Secret Pass and SNA deposits. The Company drilled approximately 49,100 feet (14,950 meters) during the quarter, compared to approximately 64,800 feet (19,750 meters) in the prior period.

Coeur plans to continue the same pace of exploration at Crown for the remainder of the year, with up to three reverse circulation rigs scheduled to conduct resource expansion and scout drilling on new targets within its 300-acre disturbance permit. The Company also expects to receive an amended permit by the end of the year to begin expanding the C-Horst discovery footprint. Additionally, Coeur is working to secure two additional core rigs for infill and metallurgical studies at C-Horst.

Given ongoing efficiencies in Coeur's exploration programs at Kensington and Wharf, the slower than anticipated ramp up of drilling activity at Rochester and industry-wide constraints on drill rig availability, the Company now expects to invest $65 - $75 million in exploration in 2021 (previously $70 - $80 million), including $48 - $53 million (previously $52 - $57 million) and $17 - $22 million (previously $18 - $23 million) of expensed and capitalized drilling, respectively.
