"We continued to deliver strong operating metrics and impressive operating cash flow," commented Gil Clausen, Copper Mountain's President and CEO. "With a healthy and increasing cash position, we are on track to advancing our organic growth objective of tripling 2020 production within the next five years, while maintaining a solid balance sheet. Our Net Debt to trailing twelve-month EBITDA⁽¹⁾ continues to improve, reaching 0.6 at the end of the quarter."

Mr. Clausen added, "In the third quarter, we completed the first step in our multi-tier growth plan with the successful installation of Ball Mill 3 at the Copper Mountain Mine. The next tier of growth is the Eva Copper Project, where project financing and basic engineering is progressing well. We also announced impressive drill results from our exploration program in the quarter at New Ingerbelle, where we doubled the vertical extent of mineralization, and at Cameron Copper, where we identified three large mineralized zones. We see exceptional exploration upside both in B.C. and in Australia and plan to continue to drill into 2022."

SUMMARY OF OPERATING RESULTS

The Copper Mountain Mine produced 22.4 million pounds of copper, 7,449 ounces of gold, and 134,987 ounces of silver in Q3 2021, as compared to 18.9 million pounds of copper, 6,630 ounces of gold, and 81,418 ounces of silver for Q3 2020. During the quarter, slightly more ore was mined from the lower grade Phase 2 area, which was planned for the commissioning of Ball Mill 3. This resulted in average mill feed grade of 0.37% Cu during the quarter, as compared to average feed grade of 0.42% Cu in the first half of 2021. The average mill feed grade in Q3 2021 was higher than Q3 2020 of 0.29% Cu.

Copper recovery was 79.7% in Q3 2021 as compared to 80.4% in Q3 2020. The Company continues to advance the installation of additional cleaner circuit capacity to support maximizing recovery on slower kinetic ore types and this is expected to be operational during the first half of 2022. The mill processed a total of 3.4 million tonnes of ore during the quarter as compared to 3.7 million tonnes in Q3 2020. Mill tonnage continued at reduced rates in Q3 2021 during periods of high grades in order to manage the volume of copper concentrate being produced. The Company is advancing the installation of additional filtration capacity in order to maintain full throughput during periods of high-grade production. This project is also expected to be complete in the first half of 2022. Mill availability averaged 92.2% for Q3 2021 as compared to 90.8% in Q3 2020. An expansion of the flotation rougher circuit is also planned to be completed in the first half of 2022 to further enhance rougher recovery.

To date, there have been no material interruptions to the Company's operations, logistics and supply chains as a result of the COVID-19 pandemic. Enhanced health and safety protocols continue to be implemented and monitored.

C1 cash cost per pound of copper produced for Q3 2021 was US$1.50, as compared to US$1.27 in Q3 2020. The increase in cost per pound in Q3 2021 was the result of higher mining costs in Q3 2021 as the mine returned to utilizing its full fleet of equipment as compared to the cost saving measures that were implemented in Q3 2020 as a result of COVID 19.

All-in sustaining costs per pound of copper produced (AISC) for Q3 2021 was US$1.77, as compared to US$1.43 in Q3 2020. AISC carries forward from C1 costs with the addition of $7.7 million in sustaining capital, lease and applicable administration expenditures in Q3 2021 as compared to $3.9 million in Q3 2020. The increase is primarily due to higher sustaining capital of $4.7 million in Q3 2021 as compared to sustaining capital of $1.4 million in Q3 2020. Sustaining capital increased from the same quarter last year as the Company completed the installation of additional new contact water management systems in the current quarter.

Total all-in costs per pound of copper produced (AIC), net of precious metal credits, for Q3 2021 was US$2.17 as compared to US$1.68 for Q3 2020. AIC carries forward from AISC with the addition of $11.3 million in deferred stripping as compared to $6.4 million deferred stripping in Q3 2020. Deferred stripping costs in Q3 2021 resulted from the Company's regular development activities as it continued to advance development of the Phase 4 pushback of the Main Pit which will continue into H1 2022. The reduced amount of deferred stripping in Q3 2020 resulted from the Company responding to the lower copper price environment and uncertainty due to the COVID-19 pandemic by resequencing short term production to lower cost mining phases to reduce operating costs.

SUMMARY OF FINANCIAL RESULTS

In Q3 2021, revenue was $137.2 million, net of pricing adjustments and treatment charges, compared to $95.0 million in Q3 2020. Q3 2021 revenue is based on the sale of 24.4 million pounds of copper, 8,308 ounces of gold, and 142,128 ounces of silver. This compares to 17.8 million pounds of copper, 6,232 ounces of gold and 67,901 ounces of silver sold in Q3 2020. As noted above, the increase in revenue is due to higher metal prices and metal sales which were somewhat offset by lower United States to Canadian dollar foreign exchange rates and a negative mark to market and final adjustment on concentrate sales of $7.6 million as compared to a positive mark to market and final adjustment of $11.3 million for Q3 2020.

Cost of sales in Q3 2021 was $70.5 million as compared to $53.0 million for Q3 2020. The increase in cost of sales can largely be attributed to the increase in volume of copper sold in Q3 2021 as compared to Q3 2020. Cost of sales is also affected by the allocation of mine operating costs to deferred stripping with $12.8 million, inclusive of $1.5 million in depreciation, allocated to deferred stripping in Q3 2021, compared to $7.8 million, inclusive of $0.8 million in depreciation, in Q3 2020.

The Company generated a gross profit of $66.6 million in Q3 2021 as compared to a gross profit of $42.0 million in Q3 2020. Net income for Q3 2021 was $25.8 million as compared to net income of $33.2 million for Q3 2020. The variance in net income in Q3 2021 as compared to Q3 2020 is a result of several items, including:

• Higher revenue due to more pounds sold at a higher average price as compared to Q3 2020.
• A $7.6 million negative mark to market and final adjustment from provisional pricing on concentrate sales in Q3 2021, as compared to an $11.3 million positive mark to market and final adjustment from provisional pricing on concentrate sales for Q3 2020, a differential of approximately $18.9 million.
• A non-cash unrealized foreign exchange loss of $7.6 million as compared to a gain of $6.9 million in Q3 2020, a differential of approximately $14.5 million, which was primarily related to the Company's debt that is denominated in US dollars.
• A non-cash deferred tax expense of $13.8 million as compared to $10.1 million for Q3 2020.

On an adjusted basis, the Company recorded a net income of $41.4 million in Q3 2021, or $0.20 per share, compared to $15.1 million in Q3 2020, or $0.08 per share.

PROJECT DEVELOPMENT UPDATE

Copper Mountain Mine, Canada

The Company successfully installed and commenced commissioning of Ball Mill 3 in the third quarter of 2021. The Company expects to add slurry to the new mill in early Q4 2021 with full capacity expected to be achieved by year end. The Ball Mill 3 Expansion Project is designed to increase mill throughput to 45,000 tonnes per day from 40,000 tonnes per day and improve copper recovery as a result of achieving a finer grind of ore.

Eva Copper Project, Australia

The Company continued to advance basic engineering and project financing during the quarter. A final capital cost, operating cost and update on project economics is expected to be complete and announced in the fourth quarter of 2021, ahead of a final construction decision.

EXPLORATION UPDATE

Canada

The exploration drilling program which was initiated in March 2021, with the objective of expanding resources and reserves at the Copper Mountain Main Pit, North Pit and New Ingerbelle continued in the third quarter. Following on favourable results, more drill rigs are expected to be added and drilling is planned to continue into the first quarter of 2022.

In the third quarter, the Company announced positive results from the drilling at New Ingerbelle. The current drill program encountered long intercepts of high-grade mineralization with continuity. For details, please see the Company's September 9, 2021 press release.

Australia

The 2021 exploration program designed to discover additional copper, copper-gold or gold deposits at the Company's Cameron Copper Project, which is situated 40 kilometres south of its Eva Copper Project, continued through the third quarter. The program, which consists of detailed geophysical, geochemical and geological surveys followed by drill testing, produced encouraging results with three mineralized zones identified. The drill program encountered intercepts of high-grade mineralization, within long, low-grade mineralized envelopes, with lateral continuity between intercepts of up to 1 kilometre. For drill hole results, please see Copper Mountain's October 12, 2021 press release.

As a result of the success to date, a second round of drill testing has begun. The Company plans to carry out further drilling that will also include new undrilled targets with significant copper-gold anomalies in surface soil and rock samples.

OUTLOOK

The Company reaffirms its upward revised 2021 production guidance of 90 to 100 million pounds of copper and the Company expects to be at the top end of the 2021 AIC guidance of US$1.80 to US$2.00 per pound due to inflationary pressures on the costs of fuel and steel used in operations.
