SUMMARY

Second Quarter Results Boosted by Strong Manitoba Operations

- Strong production and cost performance from the Manitoba operations during the quarter; an increase in production of all metals over the first quarter and record gold production driven by increasing Lalor gold grades and record gold recoveries at Stall.

- Successfully achieved efficient restart of operations at Constancia in mid-May with increased government-supported COVID-19 health and safety protocols in place.

- Second quarter net loss was $51.9 million or $0.20 per share. Second quarter adjusted net loss¹ per share was $0.15 and adjusted EBITDA¹ was $49.1 million, after adjusting for the impact of the Peru temporary suspension costs and a partial reversal of the Peru inventory write-down from last quarter.

- Operating cash flow before change in non-cash working capital decreased to $29.5 million in the second quarter of 2020 from $81.3 million in the same quarter of 2019 due to lower production at Constancia and lower realized base metal prices offset by higher realized gold prices and higher gold sales in Manitoba.

- Cash and cash equivalents increased during the second quarter to $391.1 million as at June 30, 2020 as a result of the previously announced $115.0 million gold prepay transaction and cash generated from operations, partially offset by capital investments on the New Britannia refurbishment project.

On Track to Achieve Manitoba Guidance; Updated Peru Guidance

- Owing to the outstanding performance from the Manitoba operations in the first half of 2020, and the ability to achieve safe and continuous operations despite COVID-19 operating challenges, we are on track to meet all Manitoba production and cost guidance for 2020.

- COVID-19 in Peru had a significant impact on our business in the second quarter and continues to be a risk we are actively managing. A government declared state of emergency in mid-March required the suspension of operations at Constancia for a period of eight weeks. The Constancia mill resumed full operation on May 18 processing stockpiled ore, and mining activities returned to normal levels in early July under a successful phased restart plan.

- Updated 2020 Peru production guidance of 65,000 to 75,000 tonnes of copper and 25,000 to 35,000 ounces of precious metals reflects the Constancia suspension period and the expected start of mining at Pampacancha in early 2021.

Executing on Growth Initiatives

- Fully-funded New Britannia gold mill refurbishment project remains on schedule and within budget, with detailed engineering approximately 90% complete and construction activities approximately 25% complete.

- Early mining of the gold zone at Lalor is well-underway, which is expected to result in gold production of 74,000 ounces in 2020 and 102,000 ounces in 2021. This is in preparation for the restart of the New Britannia gold mill, which is expected to increase annual gold production from Lalor to over 150,000 ounces by 2022.

- Successfully advanced Pampacancha with individual land-user agreements in place covering approximately two-thirds of the land, and land clearing activities are underway.

- Filed initial briefs with the U.S. Court of Appeals for the Ninth Circuit in June to advance the appeal of the July 2019 Rosemont court decision, which revoked the U.S. Forest Service's issuance of the Final Record of Decision for Rosemont.

- Restructured revolving credit facilities in the wake of COVID-19 to right-size the facilities and further enhance our financial flexibility during the development of the New Britannia and Pampacancha projects.

- Updated National Instrument ("NI") 43-101 resource estimate for the 1901 deposit near Lalor includes a larger base metal resource estimate and a new gold-rich inferred resource estimate of 500,000 tonnes grading 6.8 grams per tonne of gold.

Summary of Second Quarter Results

Cash generated from operating activities in the second quarter of 2020 decreased to $31.4 million compared to $107.0 million in the same quarter of 2019. Operating cash flow before change in non-cash working capital was $29.5 million during the second quarter of 2020, reflecting a decrease of $51.8 million compared to the same period of 2019. The decrease in operating cash flow is primarily the result of lower realized base metal prices as well as lower Constancia production and sales due to the temporary suspension of mine operations. This decrease was partially offset by higher gold production and sales in Manitoba as well as higher realized gold prices.

Copper-equivalent production in the second quarter of 2020 decreased by 21% compared to the same period in 2019 primarily as a result of lower ore production from Constancia due to the eight-week suspension of operations commencing mid-March 2020 following a government declared state of emergency as well as lower Constancia copper grades. However, copper-equivalent production in Manitoba increased by 9% in the second quarter over the same quarter in 2019 primarily due to a 25% increase in gold production as sustained results from the Stall mill gold recovery improvement initiatives are achieved.

Net loss and loss per share in the second quarter of 2020 were $51.9 million and $0.20, respectively, compared to a net loss and loss per share of $54.1 million and $0.21, respectively, in the second quarter of 2019. Second quarter earnings were negatively impacted by lower base metal prices, lower sales volumes due to the temporary suspension of Constancia mine operations and lower Constancia grades. In addition, the temporary suspension at Constancia resulted in fixed overhead production costs of $25.6 million during the second quarter and $31.9 million year-to-date that would normally be capitalized to inventories and property, plant, and equipment, to be immediately expensed as part of our cost of sales. This was partially offset by a $8.2 million reversal of a Peru inventory write-down due to rising copper prices in the second quarter. The below table provides a summary of COVID-19 related charges at Constancia and where each item is classified in our consolidated interim financial statements.

Financial statement category	COVID-19 related cost description	Three months ended June 30, 2020	Six months ended June 30, 2020

1 These charges are not included in our calculation of adjusted net loss and adjusted EBITDA. Adjusted net loss and adjusted EBITDA are non-IFRS financial performance measures with no standardized definition under IFRS. For further information and a detailed reconciliation, please see the discussion under the "Non-IFRS Financial Reporting Measures" section of this MD&A.

After adjusting for the temporary suspension costs in Peru and the reversal of the Peru inventory write-down, among other items, adjusted net loss¹ and adjusted EBITDA¹ in the second quarter of 2020 were $39.7 million, or $0.15 per share, and $49.1 million, respectively. This compares to an adjusted net loss and adjusted EBITDA of $8.1 million, or $0.03 per share, and $95.9 million, respectively, in the same period of 2019. The increase in adjusted net loss and decrease in adjusted EBITDA was primarily due to the same factors noted above.

On a budgeted sales volume basis, if operations at Constancia were maintained during the eight-weeks in which production was suspended, this would have resulted in approximately $108.0 million of incremental revenue and generated approximately $42.4 million of incremental year-to-date pre-tax earnings, assuming closing second quarter commodity prices. These amounts would have improved our current year-to-date reported revenue of $454.0 million and pre-tax loss of $156.1 million.

3

In the second quarter of 2020, consolidated cash cost per pound of copper produced, net of by-product credits¹, was $0.64, compared to $1.27 in the same period last year. Given the significant reduction in Constancia production in the second quarter, this measure is more heavily impacted by our Manitoba production which contains meaningful zinc and precious metal by-product revenue components, and this is not indicative of future consolidated cash costs. The overall decrease in this measure was a result of declines in Peru production costs in the second quarter exceeding a more muted decline in by-product credit revenues, due to the significant Manitoba by-product revenue component remaining unchanged compared to the same period in 2019. Incorporating sustaining capital, capitalized exploration, royalties, selling, administrative and regional costs, consolidated all-in sustaining cash cost per pound of copper produced, net of by-product credits¹, in the second quarter of 2020 was $2.26, which decreased from $2.30 in the same period last year, driven mainly by same factors noted above.

*Reflects Constancia temporary shutdown in April and May.

RECENT DEVELOPMENTS

COVID-19 Business Update

Amidst the COVID-19 pandemic, our business response plan continued to be executed throughout the quarter, building off our crisis response protocols to establish business practices to carry us through this ongoing public health situation. We remain focused on the health and safety of our workforce, their families and the communities in which we operate. Addressing the pandemic is a collective effort and we continue to actively engage with our industry associations to understand developing practices and with local stakeholders and public health authorities to ensure effective implementation of our business response plans. We closely monitor the evolution of the pandemic in each of our regions and are continuously reviewing and adapting our procedures based on the latest local situation.

Each of our business units has developed effective site-specific measures to identify and limit COVID-19 exposure and transmission and maintain a safe environment for our workers and our communities. Site-specific measures include testing of incoming workers prior to their travel to site, pre-screening protocols, quarantine periods for incoming workers, workplace physical distancing protocols, and adjustment of work rotation schedules. These measures continue to evolve as the status of the pandemic changes in each of our operating regions and our measures are adapted to the regional health authorities' latest restrictions and guidelines.

We believe the most important way we can support the communities in which we operate is to manage safe operations that provide income for local employees, businesses, and communities. In addition to our efforts to maintain safe operations, we have been supporting public health efforts and providing COVID-19 relief funding, supplies and services to our neighbouring communities. Each region has different emergency needs at this critical time. In Peru, we have donated medical equipment and supplies to the regional hospitals and have delivered food to nearby communities in need. In Manitoba, we have donated to charities that provide various forms of support to families in need.

Resumption of Operations at Constancia

On May 14, following an eight-week suspension of Constancia operations due to a government declared state of emergency, Hudbay received approval of our restart protocols from Peru's Ministry of Energy and Mines. On May 18, 2020, the Constancia processing facilities resumed full production. During the Constancia mine suspension period, a smaller workforce was maintained at the site to oversee critical aspects of the operation and pro-actively prepare detailed mine reopening plans, which helped facilitate the quick and efficient restart of operations. In an effort to ensure a steady ramp-up while minimizing the number of workers at site, the restart plan followed a two-phased approach. The initial phase utilized stockpiled ore to fill the mill for the first six weeks. This was followed by a ramp-up of mining activities, commencing the last week of June with a full ramp up to normal levels in early July.

The situation in Peru, however, remains fluid. The state of emergency, first declared by the government in response to the COVID-19 pandemic on March 15, has since been extended to August 31, 2020 and there remains a risk of further disruptions to mining operations. We are actively monitoring the situation and any potential future impact on Constancia's operations.

Annual Guidance Update

On May 14, 2020, we suspended our previously issued 2020 annual guidance for our Peru operations due to the temporary suspension of operations at Constancia and the ongoing uncertainty surrounding the COVID-19 pandemic. Following a full resumption of Constancia milling activities in mid-May and mining activities in early July, we have reissued updated 2020 annual guidance for our Peru business unit.

Our updated annual production and operating cost guidance, along with our annual capital and exploration expenditure forecasts are presented below. These forecasts incorporate the impact of regularly scheduled maintenance at our operations, including semi-annual mill maintenance at Constancia and planned maintenance on the Lalor hoist facilities during the third quarter. Our updated Peru guidance assumes we are able to continue to safely operate for the remainder of the year while adhering to our existing health protocols and those required by the Peruvian government. Our Manitoba guidance remains unchanged from previously disclosed expectations.

1 Metal reported in concentrate is prior to refining losses or deductions associated with smelter terms.
2 Precious metals production includes gold and silver production on a gold-equivalent basis, and silver is converted to gold at a ratio of 89:1.
3 Reflects combined mine, mill and G&A costs per tonne of milled ore. Peru costs reflect the deduction of expected capitalized stripping costs. Combined unit costs are non-IFRS financial performance measures with no standardized definition under IFRS. For further information, please see the discussion under the "Non-IFRS Financial Reporting Measures" section of this MD&A.
4 Excludes capital costs not considered to be sustaining or growth capital expenditures.
5 Peru growth capital expenditures include costs associated with project development and acquiring surface rights. Additional costs remain outstanding in recognition of current uses of land and the company is currently entering into agreements to address these matters.
6 Includes $20.0 million of capitalized Arizona spending associated with the Rosemont and Mason projects.
7 Includes $15.0 million of capitalized exploration resulting in total exploration expense of $10.0 million.

The revised production guidance for Peru reflects a reduction of approximately 15,000 to 20,000 tonnes of copper and 20,000 ounces of precious metals compared to the original guidance issued earlier this year, with molybdenum production only modestly affected. This reduction reflects the lost production during the eight-week temporary suspension at Constancia, in addition to revised mine plans for the remainder of the year and the resulting deferral of some higher-grade ore into 2021. The precious metals production guidance also reflects the revised expected Pampacancha production start date of early 2021, compared to the second half of 2020 previously, due to the Peruvian government declared state of emergency and the resulting impact on the Consulta Previa consultation process.

Peru sustaining capital of $80.0 million reflects the deferral of approximately $20.0 million into 2021 due to the resequencing of capital activities, such as tailings and capitalized stripping, as a result of the temporary mine suspension. The revised unit cost guidance in Peru reflects lower mining costs during the gradual ramp-up of mining activities in the second quarter of 2020. There was no change to exploration expenditure guidance.

Peru growth capital of $70.0 million is unchanged from previous guidance and includes initial expenditures for developing the Pampacancha deposit, acquiring surface rights from the local community, but excludes the costs associated with recognizing the current uses of the land by certain community members. We have made significant progress with completing these individual land-user agreements, with agreements covering approximately two-thirds of the property completed to-date and the remaining agreements expected to be completed during the third quarter of 2020. As of June 30, 2020, approximately one-third of the land has been vacated and turned over to Hudbay. We intend to update our Peru growth capital guidance for these remaining costs once all of the individual land-user agreements are completed.

Credit Facility Amendment

In the second quarter of 2020, in the wake of the COVID-19 pandemic, we entered into discussions with the syndicate of banks in our revolving credit facilities (the "Credit Facilities") to restructure the facilities in order to provide Hudbay with enhanced flexibility during the development of the New Britannia and Pampacancha projects. Each of the banks in the syndicate has received credit approval to amend the Credit Facilities on the proposed terms and the transaction is expected to close by the end of August.

8

As a result of the amendment, total available borrowings under the Credit Facilities will be $400.0 million to reflect our anticipated business requirements until June 2022 when the Credit Facilities mature. The revised covenants include maintaining a net debt to EBITDA ratio of less than 5.25:1 and an interest coverage ratio of greater than 2.50:1 until the end of 2021. Refer to the Liquidity and Capital Resources section for additional information.

Snow Lake Development and Exploration Update

New Britannia Refurbishment Activities Underway

The New Britannia refurbishment project remains on schedule and on budget. In May, we broke ground at the New Britannia site with the start of construction of the foundation for the new copper flotation building. Construction of the pipeline between the New Britannia and Stall mills continues as planned. Detailed engineering is approximately 90% complete and construction activities are approximately 25% complete to-date. Refurbishment activities are on track for completion in August 2021, with plant commissioning and ramp-up expected during the second half of 2021. Through our expertise in project development and the advancement of the detailed engineering work, we have identified the potential to produce gold from the New Britannia mill earlier than expected in 2021. We are exploring this early gold opportunity and expect to provide an update in the third quarter of 2020.

We are continuing with our plan to mine approximately 90,000 tonnes from the gold zone in 2020 as part of stope sequencing in preparation for the restart of the New Britannia gold mill. Gold production from Lalor is expected to be 74,000 ounces in 2020 and 102,000 ounces in 2021, as per the March 30, 2020 mine plan. Upon completion of the New Britannia mill refurbishment, average annual gold production from Lalor is expected to increase to over 150,000 ounces at cash costs and sustaining cash costs, net of by-product credits, of approximately $480 and $655 per ounce, respectively, during the first eight years.

1901 Deposit Updated Resource Estimate

Since its discovery in February 2019, drilling has continued to define the extent and geometry of the 1901 deposit. After announcing an initial inferred resource estimate for the two zinc-rich lenses in August 2019, the focus of the infill drill program conducted during the winter of 2020 was two-fold: to upgrade the classification of a significant portion of the inferred resources reported in August 2019, and to define an initial inferred resource estimate for the gold mineralization that had been intersected around the two zinc-rich lenses.

The 1901 deposit is located half-way between the former Chisel North mine and the Lalor mine, less than 1,000 metres from an active underground ramp at a depth ranging from 550 to 650 metres and within 15 kilometres trucking distance of both the Stall base metal concentrator and the New Britannia gold mill. The property is 100% owned by the Company, free of any royalties or streams. The mineralization is similar to Lalor with zinc-rich volcanogenic massive sulphide lenses containing high-grade gold zones and indication of a copper-gold rich feeder zone. The mineralization occurs along the hanging wall contact of the stratigraphic horizon hosting the Chisel North deposit.

The updated resource estimates for the 1901 deposit, as of July 20, 2020, are provided in the table below:

1 CIM definitions were followed for the estimation of mineral resources. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
2 Mineral resources are reported within an economic envelope defined by a mineral stope optimization algorithm assuming a selective mining method.
3 Long-term metal prices of $1,500/oz gold, $18.00/oz silver, $3.00/lb copper and $1.09/lb zinc were used for the estimation of the mineral resources.
4 Metal recovery estimates are based on the assumption that the base metal mineralization would be processed at the Stall concentrator and would present a similar performance to those experienced historically for the Chisel and Lalor zinc-rich lenses. The gold mineralization is assumed to be processed at the New Britannia concentrator, which is currently being refurbished.
5 Specific gravity measurements using industry standard techniques were completed on all assayed intervals.

High resource conversion - The upgraded base metal measured and indicated resource estimates at the 1901 deposit are equivalent to 100% of the initial tonnage of the 2019 base metal inferred resources reported in our most recent AIF, with a 12% lower zinc grade and more than double the gold grade. While the 2020 infill drilling only covered approximately two-thirds of the footprint of the 2019 mineral resource estimates, it has evidenced a larger zinc-rich resource with significant gold, silver and copper content. There remains an additional 400 thousand tonnes of base metal inferred resource estimates with attractive zinc, copper and gold content which has the potential to be upgraded to higher categories with further drilling.

Significant gold content - The 2020 drilling program was also successful in defining a new gold-rich inferred resource estimate of 500 thousand tonnes at a gold grade of 6.8 grams per tonne. Total gold resources have significantly increased with 122 thousand ounces in measured and indicated and 137 thousand ounces in inferred, compared to a total of 58 thousand inferred ounces previously, which continues to demonstrate the gold potential of the Snow Lake camp.

Conservative resource estimation method - The methodology followed to estimate mineral resources at the 1901 deposit is identical to the approach used for the Lalor mine (please refer to the NI 43-101 Technical Report for Lalor dated March 28, 2019 for more details) and constrains the resource within a stope optimization envelope that is expected to lead to a high mineral resource to mineral reserve conversion factor.

1901 Deposit Exploration Potential

There remains further opportunity to convert additional inferred material to the measured and indicated categories and to extend the resource in the northern and eastern parts of the deposit. We expect to complete a drill program in early 2021 with a focus on expanding and upgrading the 1901 resource estimate. We have also identified additional favourable exploration drill targets located between the 1901 deposit and the Lalor mine that remain to be tested.

In addition, recent drilling has identified several high-grade copper-gold zones that have not been included in the current resource estimate due to limited drilling density. Highlights of these copper-gold intersections are summarized in the table below:

Snow Lake Expansion Potential

The updated resource estimate for the 1901 deposit was planned as part of phase three of our Snow Lake gold strategy. There remain opportunities for extension and additional conversion of mineral resource estimates at the 1901 deposit and we are engaged in engineering activities to develop a viable mine plan for the 1901 deposit that could supplement production from Lalor to take advantage of the future processing capacity of our mills in the Snow Lake region.

We are also examining the potential to optimize both the Stall and New Britannia mills, which could create further value for the 1901 deposit and the Snow Lake operations. At the Stall mill, we are initiating studies to increase gold and copper recoveries. We will also be completing studies to potentially expand the New Britannia mill capacity beyond the currently planned 1,500 tonnes per day. We expect to complete these studies in the first half of 2021 as we execute the third phase of our Snow Lake gold strategy.

Constancia Regional Exploration

Our consistent approach to community negotiations has proved successful, demonstrating our strong relationships with the neighbouring communities near Constancia and positioning us well to unlock future value on our other regional growth targets in Peru. After reaching an exploration agreement with the Quehuincha community in early 2019 and subsequently completing the Consulta Previa process, we are on track to commence our planned drill program in the fall of 2020 to test a high-grade skarn target on the Quehuincha North property.

11

We are also continuing the follow-up drilling program on the previously disclosed Constancia North intersections to test a possible extension of copper porphyry and high-grade skarn mineralization occurring within 300 metres of the edge of the current Constancia pit. We expect to have the results from this drilling program in the third quarter of 2020.

Appointment of Chief Financial Officer

On June 11, 2020, Steve Douglas was appointed as Hudbay's Senior Vice President and Chief Financial Officer effective June 30, 2020. Mr. Douglas is highly regarded and brings over 25 years of resource industry and senior finance leadership experience to our executive team.

Appeal of Unprecedented Rosemont Court Decision

On June 22, 2020 we announced the filing of the Company's initial brief with the U.S. Court of Appeals for the Ninth Circuit in relation to the U.S. District Court for the District of Arizona's ("District Court") decision in July 2019, which revoked the U.S. Forest Service's ("Forest Service") issuance of the Final Record of Decision ("FROD") for the Rosemont project in Arizona. The filing of the Company's brief follows the U.S. federal government's initial brief which was filed on June 15, 2020 by the U.S. Department of Justice on behalf of the federal agencies involved in issuing the FROD. The FROD was issued in June 2017 after a thorough process involving 17 co-operating agencies at various levels of government.

The briefs explain how both the Company and the government believe that the District Court misinterpreted federal mining laws and Forest Service regulations as they apply to Rosemont. Both briefs assert that current law broadly authorizes mining-related activities, such as ore processing and tailings storage, to be conducted on open Forest Service lands. The District Court's determination that the Forest Service's mining regulations do not apply to mining activities unless those activities are conducted entirely on valid mining claims, and hence above ore bodies, is contrary to plain language reading of the general mining law, as well as Forest Service regulations, which explicitly allow for mining-related activity to occur on lands not covered by any mining claim.

On June 29, 2020, further briefs were filed by industry groups in support of Hudbay and the U.S. government's appeal. These industry groups include the National Mining Association, the American Exploration and Mining Association, and the Southern Arizona Business Coalition.

Dividend Declared

A semi-annual dividend of C$0.01 per share was declared on August 11, 2020. The dividend will be paid on September 25, 2020 to shareholders of record as of September 4, 2020.

BlackNorth Initiative

Hudbay's President and Chief Executive Officer, Peter Kukielski, recently joined other senior executives from Canadian public companies in a pledge to take action to end systemic racism and create opportunities for all of those in the underrepresented BIPOC (Black, Indigenous and People of Colour) community. The pledge is part of the BlackNorth Initiative and the recently formed Canadian Council of Business Leaders Against Anti-Black Systemic Racism. The BlackNorth Initiative aligns with our values of dignity and respect, caring, openness and trustworthiness that are inherent in our corporate culture and in our decision-making and actions. Our community engagement efforts are focused around creating opportunities for all members of the communities in which we operate. Through the BlackNorth Initiative, we intend to expand our efforts to help end systemic racism.

Following the government-mandated mid-March suspension of operations at Constancia, the mine remained closed for approximately eight weeks and resumed operations in mid-May, achieving normal mill throughput levels on May 18, within 48 hours after restart, and continued at these levels for the remainder of the second quarter. The initial six weeks following restart focused on milling activities while processing stockpile ore. This was followed by a ramp-up of mining activities commencing the last week of June with a full ramp-up to normal levels in early July. Enhanced health and safety measures were implemented upon the re-start of operations and remain in place as we continue to monitor the local impacts of the COVID-19 pandemic.

Ore milled at our Constancia mine during the second quarter of 2020 was 43% lower compared to the same period in 2019 due to the temporary shutdown of Constancia. Milled copper grades in the second quarter were approximately 8% lower than the same period in 2019 as mainly lower grade stockpile ore was processed during the quarter. Copper recoveries in the second quarter of 2020 decreased by 10% compared to the same period in 2019 due to processing of mainly lower grade stockpiled ore.

Combined mine, mill and G&A unit operating costs in the second quarter of 2020 were 25% lower than the same period in 2019, primarily due to lower operating costs as a result of constrained activity during the state of emergency, and significantly reduced mining costs during the quarter. We also deferred a second quarter planned plant maintenance shutdown from May to the third quarter, as a result of completing proactive plant maintenance during the eight-week temporary suspension.

Year-to-date production variances were affected by the same factors as the second quarter variances versus prior year.

2 Precious metals production includes gold and silver production on a gold-equivalent basis. For 2019, silver is converted to gold at a ratio of 70:1. For 2020, silver is converted to gold at a ratio of 89:1.

In the second quarter of 2020 production of copper, gold and silver were 53%, 39%, and 54% lower, respectively, than the same period in 2019, as the temporary mine suspension and generally lower grades resulted in reduced production during the quarter. Production in the second half of the quarter, following the resumption of operations, was consistent with volumes from the same period in 2019. For the first half of 2020, production of copper, gold and silver were 45%, 41%, and 40% lower, respectively, compared to the first half of 2019 for the same reasons as the second quarter variances. Molybdenum production was similarly affected.

Peru's updated 2020 production guidance has been revised to reflect the lost production during the eight-week temporary suspension at Constancia, in addition to revised mine plans for the remainder of the year and the resulting deferral of some higher-grade ore into 2021. Our updated guidance assumes we will be able to continue to safely operate for the remainder of the year while adhering to our existing health protocols and those required by the Peruvian government.

Cash cost per pound of copper produced, net of by-product credits, for the three and six months ended June 30, 2020 were $1.56 and $1.61, respectively. Cash cost remained relatively consistent quarter over quarter, however, increased 17% on a year-to-date basis. The overall increase is primarily due to lower copper production as a result of the temporary shutdown and lower copper grades and recoveries, as well as lower by-product credits, partially offset by lower combined operating costs.

Sustaining cash cost per pound of copper produced, net of by-product credits, remained consistent quarter over quarter; however, increased by 23% on a year-to-date basis. The overall increase is primarily due to the same factors noted above affecting cash costs partially offset by lower sustaining capital due to a curtailment of activity during the eight-week shutdown.

The Manitoba business unit had solid operating performance across the mines, mills and zinc plant during the second quarter. In response to the COVID-19 pandemic, we have worked collaboratively with our health and safety committees and the local health units with a focus on keeping our employees and communities safe by implementing a number of layered workplace controls. As a result, the second quarter Manitoba operating results were largely unaffected by the COVID-19 pandemic and are on track to achieve annual production and cost guidance.

Operational performance during the second quarter at both Lalor and 777 was strong, with ore production generally in line and grades largely exceeding the same period in 2019. The enhanced precious metal production from Lalor, driven by improved gold and silver grades is a result of prioritizing resources within the higher value portions of the base metal lenses. Development in the gold rich lenses 25 and 27 advanced ahead of schedule, and production from these areas is expected ahead of the New Britannia mill restart as Lalor transitions to a gold mine. Higher 777 ore grades during the second quarter of 2020 were expected and consistent with the mine plan which included the mining of higher-grade copper stopes during the quarter. As a result, both second quarter and year-to-date gold and silver grades mined in Manitoba increased significantly, while base metal grades were consistent with the same comparative periods in 2019.

Total unit operating costs for the second quarter of 2020 decreased by 8% compared to the same period in 2019 mainly due to lower operating costs at Lalor. Year-to-date total unit operating costs in Manitoba similarly decreased by 7% for the same reason.

At the Stall concentrator, ore processed during the second quarter of 2020 was generally consistent with the same period in 2019, despite a planned two-week outage on one of the grinding lines for capital upgrades. Gold and silver recoveries during the quarter increased by 19% and 10%, respectively, compared to the same period in 2019 due to a combination of improved ore characteristics and numerous operational improvement projects implemented at the Stall mill. Ore processed in the Flin Flon concentrator in the second quarter of 2020 decreased by 11% compared to the same period in 2019 due to less Lalor ore required to be processed in Flin Flon as a result of higher throughput at the Stall mill. Furthermore, operational optimization between the 777 mine and the Flin Flon mill, which provides input feed for paste backfill to the mine, led to lower milling activity and a corresponding increase of the ore stockpile at quarter end.  Metal recoveries at the Flin Flon concentrator during the second quarter of 2020 decreased slightly compared with the same period in 2019, which was in line with metallurgical models.

Unit operating costs at Stall decreased slightly in the second quarter of 2020 compared to the same period in 2019, whereas unit operating costs at Flin Flon were 16% higher over the same period because of reduced ore throughput.  Manitoba combined mine, mill and G&A unit operating costs in the second quarter of 2020 remained unchanged compared to the same period in 2019.

Year-to-date ore processed at Stall increased by 7% as a result of several continuous improvement initiatives and higher ore availability from the Lalor mine. Year-to-date ore processed at the Flin Flon mill remained largely unchanged from the same period in 2019.

Year-to-date combined mine, mill and G&A unit operating costs were 6% lower as the mines and mills delivered consistent results with less production disruptions.

In the second quarter of 2020, copper, gold and silver production was 6%, 25%, and 26% higher compared to the same period in 2019 due to higher head grades and higher gold and silver recoveries. Zinc production declined by 2%, in the second quarter of 2020. Year-to-date, gold, silver and zinc production increased by 29%, 16% and 3%, respectively, due to higher throughput and higher gold and silver head grades. Year-to-date copper production decreased by 3% as head grades decreased.

Cash cost per pound of copper produced, net of by-product credits, in the second quarter of 2020 was negative $1.00. These costs were lower compared to the same period in 2019, primarily as a result of lower mining costs, higher by-product credits and higher copper production.

Sustaining cash cost per pound of copper produced, net of by-product credits, in the second quarter of 2020 was $1.67. These costs were lower compared to the same period in 2019, primarily due to the reasons listed above slightly offset by increased sustaining capital expenditures.

Cash cost and sustaining cash cost per pound of zinc produced, net of by-product credits, in the second quarter of 2020 were lower than the same period last year as a result of significantly higher by-product credits and lower mining costs, partially offset by lower zinc production and higher sustaining capital expenditures.

Cash cost and sustaining cash cost per pound of zinc produced, net of by-product credits, were lower in the first half of 2020 compared to the same period in 2019 due to increased zinc production, significantly higher by-product credits and lower mining costs, partially offset by higher sustaining capital expenditures.

OUTLOOK

This outlook includes forward-looking information about the markets for the commodities we produce. For additional information on forward-looking information, refer to the "Forward-Looking Information" section of this MD&A. We may update our outlook depending on changes in metals prices and other factors. In addition to this section, refer to the "Operations Review" and "Financial Review" sections for additional details on our outlook for 2020.

Commodity Markets

In March 2020, the World Health Organization declared the COVID-19 outbreak a global pandemic. The current and future impacts on global commerce are anticipated to be far-reaching. To date, there has been significant volatility in stock markets, commodities and foreign exchange markets, restrictions on the conduct of business in many jurisdictions and the global movement of people and some goods have become restricted. Containment measures have resulted in significantly decreased economic activity in the second quarter of 2020, which has adversely affected the broader global economy.

Our 2020 operational and financial performance will be influenced by a number of factors. At the macro-level, the impact of COVID-19 and the general performance of the Chinese, North American and global economies will influence future demand for our products. The realized prices we achieve in the commodity markets significantly affect our financial performance. To date, we have experienced production below estimated levels and reduced revenue.

Copper and zinc prices declined by 20% or more in response to the COVID-19 pandemic, reaching lows in March of $2.08 per pound and $0.83 per pound, respectively. Since that time, liquidity injections by central banks and government stimulus in all parts of the globe, combined with actual and projected supply disruptions in copper and zinc mining operations, have seen prices of both metals rebound dramatically with copper hitting fresh 2020 highs in the $2.90 range in July.  Gold prices have also been very volatile, initially dropping approximately $200 per ounce in response to the global asset sell off in March before fears of future inflation stemming from the response of central banks and governments to COVID-19 drove prices to all-time record levels above $2,000/oz in early August.

We remain confident in the longer-term outlook for the commodities we produce; however, there is significant ongoing short to medium-term uncertainty surrounding COVID-19 and the extent and duration of the impacts that it may have on demand and prices for the commodities we produce, on our suppliers, on our employees and on global financial markets. As a result, our financial results may remain volatile as COVID-19 continues to affect production, operating costs and the prices we receive for our products.

FINANCIAL REVIEW

Financial Results

In the second quarter of 2020, we recorded a net loss of $51.9 million compared to a loss of $54.1 million for the same period in 2019, representing a marginal increase in earnings of $2.2 million. Year-to date in 2020, we recorded a net loss of $128.0 million compared to a loss of $67.5 million in the same period in 2019, a decrease in profit of $60.5 million.

The following table provides further details on these variances:

Revenue

Revenue for the second quarter of 2020 was $208.9 million, $120.5 million or 37% lower than the same period in 2019, primarily as a result of significantly lower sales volumes in Peru as a result of an eight-week shutdown at Constancia through to May 18. The lag in concentrate shipments resulted in Peru's first shipment for the quarter occurring in June. Revenues from Manitoba during the quarter were also lower compared to the same period in 2019, due to lower realized base metal prices, partially offset by higher realized gold prices and higher zinc sales volumes.

Year-to-date revenue in 2020 was $454.0 million, $167.7 million or 27% lower than the same period in 2019 largely due to the same reasons as the quarterly variance, partially offset by a variable consideration adjustment on our stream revenue.

Realized sales prices

This measure is intended to enable management and investors to understand the average realized price of metals sold to third parties in each reporting period. The average realized price per unit sold does not have any standardized meaning prescribed by IFRS, is unlikely to be comparable to similar measures presented by other issuers and should not be considered in isolation or a substitute for measures of performance prepared in accordance with IFRS.

For sales of copper, gold and silver we may enter into non-hedge derivatives ("QP hedges") which are intended to manage the provisional pricing risk arising from quotational period terms in concentrate sales agreements. The QP hedges are not removed from the calculation of realized prices. We expect that gains and losses on QP hedges will offset provisional pricing adjustments on concentrate sales contracts.

Our realized prices for the second quarter in 2020 and 2019, respectively, are summarized below:

			Realized prices1 for the		LME YTD 20202	Realized prices1 for the

2 London Metal Exchange average for copper and zinc prices.
3 All sales for the three and six months ended June 30, 2020 and 2019 were cast zinc metal. Zinc realized prices include premiums paid by customers for delivery of refined zinc metal, but exclude unrealized gains and losses related to non-hedge derivative contracts that are included in zinc revenues.
4 Sales of gold and silver from our 777 and Constancia mines are subject to our precious metals stream agreement with Wheaton Precious Metals, pursuant to which we recognize deferred revenue for precious metals deliveries and also receive cash payments. Stream sales are included within realized prices and their respective deferred revenue and cash payment rates can be found on page 30.

Cost of sales related to Peru decreased for the second quarter of 2020 compared to the same period of 2019 by $75.6 million. The decrease is primarily the result of less overall mining, milling, general and administrative costs, and units-of-production depreciation due to the temporary suspension of operations at Constancia, as well as a $25.6 million fixed overhead charge (cash: $12.4 million, non-cash: $13.2 million included in depreciation) that ordinarily would have been capitalized to inventories and property, plant, and equipment.  There was also a reversal of a prior period inventory write-down in Peru of $8.2 million to reflect higher realizable inventory values resulting from an increase in copper prices. In Manitoba, cost of sales increased by $10.9 million compared to the second quarter of 2019 primarily as a result of higher depreciation costs from an increase to our decommissioning and restoration obligation and as well as a drawdown of inventory during the quarter.

Year-to-date, cost of sales was $488.7 million, which was $38.1 million less than the same period in 2019. The temporary suspension of operations at Constancia for eight weeks due to the government declared state of emergency resulted in an adjustment to cost of sales by $31.9 million of fixed overhead costs (cash: $15.8 million, non-cash: $16.1 million included in depreciation) that would ordinarily have been capitalized to inventories and property, plant, and equipment. These direct charges were offset by lower mining, milling, general and administrative, and freight and units-of-production depreciation costs resulting from lower production.

For details on unit operating costs refer to the respective tables in the "Operations Review" section of this MD&A.

31

For the second quarter of 2020, other significant variances in expenses from operations, compared to the same period in 2019, include the following:

- Other expenses decreased by $27.6 million compared to the second quarter of 2019 primarily due to the write down of a joint venture receivable related to the purchase of the remaining interest in the Rosemont development project from prior year of $26.0 million whereas no comparable charge was recorded in the current quarter.

For 2020 year-to-date, other significant variances in expenses from operations, compared to 2019, include the following:

- Selling and administrative expense decreased by $9.5 million compared to the same period in 2019. This decrease was mainly due to lower stock-based compensation charges as a result of the relative impact of the revaluation of previously issued share units to lower share prices and a general reduction in consulting, travel and legal overhead costs.

- Other expenses decreased by $33.8 million due to the write down of a joint venture receivable from prior year of $26.0 million as well as the recognition of a delivery obligation related to the Pampacancha deposit from prior year of $7.5 million, neither of which reoccurred in the current year.

1 Includes interest income and other finance expense.
2 Includes variable consideration adjustment (prior periods).
3 Includes accretion on community agreements, unwinding of discount on provisions, and net foreign exchange losses (gains).

Compared to the three months ended June 30, 2019, net finance expense increased by $8.0 million.  Accrued finance costs increased by $2.4 million due to lower interest income earned on our cash balances. Non-cash finance costs increased by $5.6 million primarily as a result of $7.6 million in losses recorded on the revaluation of our gold prepayment liability, partially offset by $4.1 million in gains on our investments measured through profit or loss consisting of securities in Canadian metals and mining companies. In addition, we recorded $3.3 million in interest charges, as we no longer capitalize interest costs on the Rosemont project effective of October 1, 2019, due to its delay in development.

32

On a year-to-date basis, net finance expense increased by $13.1 million compared to the same period in 2019 mainly for the reasons as described above and due to higher losses from the non-cash revaluation of certain embedded derivatives measured through profit or loss. Offsetting this increase is a reduction in non-cash accretion expense on our stream arrangements by $5.9 million from the same period in 2019 due to a reduction in the variable consideration adjustment compared to a similar adjustment recorded in the first half of 2019.

Tax Recovery

For the three and six months ended June 30, 2020, tax recovery increased by $33.0 million and $33.5 million, respectively, compared to the same period in 2019. The following table provides further details:

	Three months ended			Six months ended

1 Deferred tax (recovery) expense represents our draw down/increase of non-cash deferred income and mining tax assets/liabilities.

Income Tax Recovery

Applying the estimated Canadian statutory income tax rate of 27.0% to our loss before taxes of $156.1 million for the year-to-date period in 2020 would have resulted in a tax recovery of approximately $42.1 million; however, we recorded an income tax recovery of $27.2 million. The significant items causing our effective income tax rate to be different than the 27.0% estimated Canadian statutory income tax rate include:

- Decrease in the deferred tax recovery of approximately $8.5 million as certain non-monetary assets are recognized at historical cost while the tax bases of the assets change as the exchange rates fluctuates, which creates taxable temporary differences.

- Certain deductible temporary differences mostly with respect to Peru, and mostly relating to the decommissioning and restoration liabilities, were not recognized as we have determined that it is not probable that we will realize the recovery of these deferred tax assets based on the timing of the reversals of the deductible temporary differences and the future projected taxable profit of the Peruvian operations.  This has resulted in deferred tax expense of $8.0 million.

- Certain deductible temporary differences with respect to our foreign operations are recorded using an income tax rate other than the Canadian statutory income tax rate of 27%, resulting in a deferred tax recovery of $2.4 million.

33

Mining Tax Recovery

Applying the estimated Manitoba mining tax rate of 10.0% to our loss before taxes of $156.1 million for the year-to-date period in 2020 would have resulted in a tax recovery of approximately $15.6 million; however, we recorded a mining tax recovery of $0.8 million. Effective mining tax rates can vary significantly based on the composition of our earnings and the expected amount of mining taxable profits. Corporate costs and other costs not related to mining operations are not deductible in computing mining profits. A brief description of how mining taxes are calculated in our various business units is discussed below.

Manitoba

The Province of Manitoba imposes mining tax on profit related to the sale of mineral products mined in the Province of Manitoba (mining taxable profit) at the following rates:

- 10% of total mining taxable profit if mining profit is C$50 million or less;

- 15% of total mining taxable profit if mining profits are between C$55 million and C$100 million; and

- 17% of total mining taxable profit if mining profits exceed C$105 million.

We estimate that the tax rate that will be applicable when temporary differences reverse will be approximately 10.0%.

Peru

The Peruvian government imposes two parallel mining tax regimes, the Special Mining Tax and the Modified Royalty, on companies' operating mining income on a sliding scale, with progressive rates ranging from 2.0% to 8.4% and 1.0% to 12.0%, respectively. Based on financial forecasts, we have recorded a deferred tax liability as at June 30, 2020, at the tax rate we expect to apply when temporary differences reverse.

LIQUIDITY AND CAPITAL RESOURCES

In the second quarter of 2020, in the wake of the COVID-19 pandemic, we entered into discussions with the syndicate of banks in our revolving Credit Facilities to restructure the facilities in order to right-size the facilities and provide Hudbay with enhanced flexibility during the development of the New Britannia and Pampacancha projects. Each of the banks in the syndicate has received credit approval to amend the Credit Facilities on the proposed terms and the transaction is expected to close by the end of August.

As a result of the amendment, the total size of the Credit Facilities will decrease from $550.0 million to $400.0 million to reflect our anticipated business requirements until June 2022 when the Credit Facilities mature. The revised covenants are as follows:

- Maintaining net debt to EBITDA ratio of less than:

• 5.25:1 from September 30, 2020 to December 31, 2021; and,

• 3.50:1 from January 1, 2022 to maturity.

- Maintaining an interest coverage ratio of greater than:

• 2.50:1 from September 30, 2020 to December 31, 2021; and,

• 3.00:1 from January 1, 2022 to maturity.

- Maintaining a minimum liquidity greater than $50 million to December 31, 2021.

The EBITDA calculation for the purposes of the covenants may differ from the non-IFRS measure of adjusted EBITDA shown in this MD&A. As at June 30, 2020, our liquidity includes $391.1 million in cash and cash equivalents as well as undrawn availability under our Credit Facilities. As at June 30, 2020, we were in compliance with our covenants under the Credit Facilities and we have drawn $107.0 million in letters of credit under the Credit Facilities.

34

As at June 30, 2020, the Arizona business unit had $8.6 million in surety bonds and the Peru business unit had $20.0 million in surety bonds, issued to support future reclamation and closure obligations. The Peru business unit also had $45.0 million in letters of credit issued with various Peruvian financial institutions. No cash collateral is required to be posted under these letters of credit or surety bonds.

Financial Condition

Financial Condition as at June 30, 2020 compared to December 31, 2019

Cash and cash equivalents decreased by $5.0 million during the first half of the year to $391.1 million as at June 30, 2020. This decrease was mainly the result of $98.8 million of capital investments primarily at our Peru and Manitoba operations, and interest payments and other leasing and financing cost payments of $37.4 million and $25.4 million, respectively. This decrease was partially offset by $115.0 million of proceeds from the gold prepay transaction and cash flow from operating activities of $40.5 million. We hold the majority of our cash and cash equivalents in low-risk, liquid investments with major Canadian and Peruvian financial institutions.

Working capital decreased by $10.6 million to $260.7 million from December 31, 2019 to June 30, 2020, primarily due to an increase in our other current financial liabilities by $52.5 million arising mainly from the execution of the Pampacancha surface rights agreement and other community agreements, partially offset by a decrease of accounts payable by $28.8 million due to reduced accruals from lower operating activity at Constancia, and a reduction of the current portion of deferred revenue by $12.1 million based on changes in expected future stream deliveries.

Cash Flows

The following table summarizes our cash flows for the three and six months ended June 30, 2020 and June 30, 2019:

(in $ thousands)	Three months ended			Six months ended
	Jun. 30, 2020	Jun. 30, 2019		Jun. 30, 2020	Jun. 30, 2019
Operating cash flow before changes in non-cash working capital	29,457	81,259		71,409	166,941
Change in non-cash working capital	1,911	25,750		(30,954)	1,767
Cash generated from operating activities	31,368	107,009		40,455	168,708
Cash (used in) generated by investing activities	(47,409)	(90,881)		(97,356)	(130,144)
Cash generated by (used in) financing activities	102,372	(12,089)		50,440	(64,342)
Effect of movement in exchange rates on cash and cash equivalents	(1,192)	(379	)	1,451	(192)
Increase (decrease) in cash and cash equivalents	85,139	3,660		(5,010)	(25,970)

Cash Flow from Operating Activities

Cash generated from operating activities was $31.4 million during the second quarter of 2020, a decrease of $75.6 million compared with the same period in 2019. Operating cash flow before change in non-cash working capital was $29.5 million during the second quarter of 2020, reflecting a decrease of $51.8 million compared to the second quarter of 2019. The decrease in operating cash flow is primarily the result of lower copper sale volumes due to the temporary shutdown of the Constancia operations during the quarter and lower realized base metal prices compared to the second quarter of 2019.

Year-to-date cash generated from operating activities was $40.5 million, representing a decrease of $128.3 million compared to the same period in 2019. Operating cash flow before change in non-cash working capital was $71.4 million during the first half of 2020, compared to $166.9 million during the same period in 2019. The year-to-date decrease in operating cash flow is due to the same factors described above for the quarter-over-quarter variance.

35

Cash Flow from Investing and Financing Activities

During the second quarter of 2020, we generated $55.0 million in investing and financing activities, primarily driven by $115.0 million of proceeds received from the gold prepay, offset by $47.8 million of capital expenditures, capitalized lease payments of $8.2 million, and finance costs paid of $4.4 million.

Year-to-date, we used $46.9 million in investing and financing activities, composed primarily of $98.8 million of capital expenditures, interest payments of $37.4 million, capitalized lease payments of $17.2 million and net finance fees of $8.2 million, partially offset by $115.0 million of proceeds received from the gold prepayment transaction.

Capital Expenditures

The following summarizes accrued and cash additions to capital assets for the periods indicated:

	Three months ended				Six months ended				Guidance

1 Reflects Manitoba guidance issued February 20, 2020 and updated Peru guidance issued August 11, 2020.
2 Peru sustaining capital expenditures includes capitalized stripping costs.
3 Other capitalized costs include decommissioning and restoration adjustments.

Sustaining capital expenditures in Manitoba for the three and six months ended June 30, 2020 were $27.2 million and $51.0 million respectively, representing an increase of $0.1 million and a decrease of $0.2 million compared to the same period in 2019. Expenditures remain consistent period over period as we continue capital development projects at Lalor.

Sustaining capital expenditures in Peru for the three and six months ended June 30, 2020 were $6.6 million and $19.2 million respectively, representing decreases of $11.5 million and $9.3 million from the same period in 2019. The decrease in Peru sustaining capital expenditures compared to the same period last year was mainly due to the temporary suspension of operations at Constancia. Expenditures for the current quarter mostly related to deferred mine equipment overhauls and plant recovery improvement projects.

Year-to-date Peru growth capital of $70.2 million includes the recognition of future spending obligations arising from the execution of the surface rights agreement with the local community and agreements related to current uses of the land by certain community members. Significant progress has been made with the agreements in recognition of current land uses and as of June 30, 2020, over one-third of the land has been vacated. The majority of expenditures under these agreements is expected to be paid during the third quarter of 2020.

36

Year-to-date Manitoba growth capital of $14.7 million includes spending for the New Britannia refurbishment project which formally broke ground in May 2020 with the start of construction of the foundation for the new copper flotation building.

Other capitalized costs for the three and six months ended June 30, 2020 were $17.0 million and $60.2 million, respectively, and relate primarily to the remeasurement of previously recognized decommissioning and restoration liabilities at our Peru and Manitoba operations as a result of declining discount rates during the first half of 2020.

Capital Commitments

As at June 30, 2020, we had outstanding capital commitments in Canada of approximately $45.0 million of which $43.9 million can be terminated, approximately $36.4 million in Peru primarily related to exploration option agreements, all of which can be terminated, and approximately $178.6 million in Arizona, primarily related to our Rosemont project, of which approximately $87.7 million can be terminated.

Contractual Obligations

The following table summarizes our significant contractual obligations as at June 30, 2020:

38

In addition to the contractual obligations included in the above payment schedule, we also have the following commitments which impact our financial position:

- A profit-sharing plan with most Manitoba employees;

- A profit-sharing plan with all Peru employees;

- Wheaton precious metals stream agreements for the 777 mine and Constancia mines;

- A net smelter returns royalty agreement related to the 777 mine; and,

- Government royalty payments related to the Constancia mine.

Outstanding Share Data

As of August 10, 2020, there were 261,272,151 common shares of Hudbay issued and outstanding. In addition, there were 1,581,385 stock options outstanding.

FINANCIAL RISK MANAGEMENT

Impact of COVID-19

As a result of the COVID-19 global pandemic, we have experienced operational, supply chain, travel, labour and shipping disruptions, and may continue to experience similar disruptions in the future. As a result, our financial results may remain volatile as COVID-19 continues to affect production, operating costs and the prices we receive for our products. The resumption of normal operating activities is highly dependent on the global response and impact of the COVID-19 global pandemic. We expect that our current liquidity together with cash flows from operations will be sufficient to meet our liquidity needs in 2020.

Metals Price Strategic Risk Management

From time to time, we maintain price protection programs and conduct commodity price risk management to reduce risk through the use of financial instruments.

Commodity prices are a key driver of our financial and operational results.  Our strategic objective is to provide our investors with exposure to base metals prices, unless a reason exists to implement a hedging arrangement.

In the normal course, we typically consider base metal price hedging:

- In conjunction with a major capital commitment to a growth opportunity for which operating cash flow is a key funding source;

- To ensure the viability of a shorter life and/or higher cost mine;

- To manage the risk associated with provisional pricing terms in concentrate purchase and sale agreements;

- To offset fixed price zinc sales contracts with customers.

During the second quarter of 2020, we entered into a gold forward sale and prepay transaction which generated $115.0 million in cash proceeds to pre-fund the full capital budget of the New Britannia gold mill refurbishment. The transaction valued the future gold ounce delivery obligation for 79,954 gold ounces in 2022 and 2023 at forward curve prices averaging approximately $1,682 per ounce. The gold delivery obligation is to be satisfied with a monthly delivery of 3,331 gold ounces over a 24-month period from January 2022 to December 2023.

On an ongoing basis, we typically enter into copper hedging transactions intended to manage the risk associated with provisional pricing terms in concentrate sales agreements.

As at June 30, 2020, we had 17,650 tonnes of copper fixed for floating swaps outstanding at an average fixed receivable price of $2.55/lb associated with provisional pricing risk in concentrate sales agreements. These swaps settle across July to December 2020.

39

To provide a service to customers who purchase zinc from our plants and require known future prices, we enter into fixed price sales contracts. To ensure that we continue to receive a floating or unhedged realized zinc price, we enter into forward zinc purchase contracts that effectively offset the fixed price sales contracts with our customers.

From time to time, we enter into gold and silver forward sales contracts to hedge the commodity price risk associated with the future settlement of provisionally priced deliveries. We are generally obligated to deliver gold and silver to Wheaton prior to the determination of final settlement prices. These forward sales contracts are entered into at the time we deliver gold and silver to Wheaton and are intended to mitigate the risk of subsequent adverse gold and silver price changes. Gains and losses resulting from the settlement of these derivatives are recorded directly to revenue, as the forward sales contracts do not achieve hedge accounting, and the associated cash flows are classified in operating activities. Our swap agreements are with counterparties we believe to be creditworthy and do not require us to provide collateral.

Interest Rate and Foreign Exchange Risk Management

To the extent that we incur indebtedness at variable interest rates to fund our growth objectives, we may enter into interest rate hedging arrangements to manage our exposure to short-term interest rates. To the extent that we make commitments to capital expenditures denominated in foreign currencies, we may enter into foreign exchange forwards or acquire foreign currency outright, which may result in foreign exchange gains or losses in our consolidated interim income statements.

At June 30, 2020, approximately $359.0 million of our cash and cash equivalents was held in US dollars, approximately $21.0 million of our cash and cash equivalents was held in Canadian dollars, and approximately $11.1 million of our cash and cash equivalents was held in Peruvian soles.

2 Operating cash flow before changes in non-cash working capital.

The COVID-19 pandemic had a significant impact on our business in the first half of 2020, adversely impacting both production and base metal prices. Due to the temporary suspension of operations at Constancia throughout April and into mid-May 2020, we had lower second quarter production and sales volumes and higher production costs by $25.6 million as a result of the immediate recognition of fixed overhead production costs incurred during the suspension. With the Constancia suspension having commenced mid-March, first quarter sales volumes were less impacted. Despite this, first quarter results reflected $6.3 million of shutdown-related production costs as well as an inventory write-down of $10.4 million triggered by lower copper prices.

In 2019, the lower realized prices for copper and zinc, combined with a trend towards lower copper grades in the Constancia mine plan and the closure of the Reed copper mine in August 2018 resulted in lower revenues and gross margin, despite the lower Constancia grades being partially offset by higher mill throughput and recoveries. Earnings in 2019 were also impacted by an after-tax impairment charge of $242.1 million in the third quarter of 2019 following the U.S. District Court for the District of Arizona's decision related to the Rosemont project permits, as well as a write down of $26.0 million related to the UCM receivable in the second quarter of 2019 which was exchanged for higher ownership in the Rosemont project prior to purchasing the remaining interest from UCM. In the first quarter of 2019, pre-tax revenue and finance expenses were negatively impacted by a $22.3 million charge due to a deferred revenue adjustment arising from higher reserves and resources.

NON-IFRS FINANCIAL PERFORMANCE MEASURES

We have added adjusted net earnings (loss) and adjusted EBITDA to our non-IFRS financial performance measures this quarter. Adjusted net earnings (loss), adjusted net earnings (loss) per share, adjusted EBITDA, net debt, cash cost, sustaining and all-in sustaining cash cost per pound of copper produced, cash cost and sustaining cash cost per pound of zinc produced and combined unit cost and zinc plant unit cost are non-IFRS performance measures. These measures do not have a meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS and are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. Other companies may calculate these measures differently.

Management believes adjusted net earnings (loss) and adjusted net earnings (loss) per share better reflect the Company's performance for the current period and are better indications of its expected performance in future periods. These measures are used internally by the Company to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, the Company believes these measures are useful to investors in assessing the Company's underlying performance. We provide adjusted EBITDA to help users analyze our results and to provide additional information about our ongoing cash generating potential in order to assess our capacity to service and repay debt, carry out investments and cover working capital needs. Net debt is shown because it is a performance measure used by the Company to assess our financial position. Cash cost, sustaining and all-in sustaining cash cost per pound of copper produced are shown because we believe they help investors and management assess the performance of our operations, including the margin generated by the operations and the Company. Cash cost and sustaining cash cost per pound of zinc produced are shown because we believe they help investors and management assess the performance of our Manitoba operations. Combined unit cost and zinc plant unit cost is shown because we believe they help investors and management assess our cost structure and margins that are not impacted by variability in by-product commodity prices.

In the first half of 2020, a government-imposed shutdown of non-essential businesses led to a temporary suspension of our Constancia mining operations. As such, fixed overhead production costs incurred during the suspension were directly charged to cost of sales. These costs did not contribute to production of inventory and were therefore excluded from the calculations of adjusted net earnings (loss), adjusted EBITDA and cash costs.

Adjusted Net Earnings (Loss)

Adjusted net earnings (loss) represents net earnings (loss) excluding certain impacts, net of taxes, such as changes in estimates of asset retirement obligations at closed sites, mark-to-market adjustments, impairment charges and reversal of impairment charges, write-down of assets, and foreign exchange (gain) loss. These measures are not necessarily indicative of net earnings (loss) or cash flows as determined under IFRS.

The following table provides a reconciliation of earnings (loss) per the consolidated interim income statements, to adjusted net earnings (loss) for the three and six months ended June 30, 2020 and 2019.

After adjusting reported net loss for those items not considered representative of the Company's core business or indicative of future operations, the Company had an adjusted net loss in the second quarter 2020 of $39.7 million or $0.15 loss per share.

Adjusted EBITDA

Adjusted EBITDA is profit or loss before net finance expense/income, tax expense/recoveries, depreciation and amortization of property, plant and equipment and deferred revenue, as well as certain other adjustments. We calculate adjusted EBITDA by excluding certain adjustments included within our adjusted net earnings measure which we believe reflects the underlying performance of our core operating activities. The measure also removes the impact of non-cash items and financing costs that are not associated with measuring the underlying performance of our operations. However, our adjusted EBITDA is not the measure defined as EBITDA under our senior notes or revolving credit facilities and may not be comparable with performance measures with the same name reported by other companies. Adjusted EBITDA should not be considered as a substitute for profit or loss or as a better measure of liquidity than operating cash flow, which are calculated in accordance with IFRS. We provide adjusted EBITDA to help users analyze our results and to provide additional information about our ongoing cash generating potential in order to assess our capacity to service and repay debt, carry out investments and cover working capital needs.

Cash Cost, Sustaining and All-in Sustaining Cash Cost (Copper Basis)

Cash cost per pound of copper produced ("cash cost") is a non-IFRS measure that management uses as a key performance indicator to assess the performance of our operations. Our calculation designates copper as our primary metal of production as it has been the largest component of revenues. The calculation is presented in four manners:

- Cash cost, before by-product credits - This measure is gross of by-product revenues and is a function of the efforts and costs incurred to mine and process all ore mined. However, the measure divides this aggregate cost over only pounds of copper produced, our primary metal of production. This measure is generally less volatile from period to period, as it is not affected by changes in the price received for by-product metals. It is, however, significantly affected by the relative mix of copper concentrate and finished zinc production, where the sale of the zinc will occur later, and an increase in production of zinc metal will tend to result in an increase in cash cost under this measure.

- Cash cost, net of by-product credits - In order to calculate the net cost to produce and sell copper, the net of by-product credits measure subtracts the revenues realized from the sale of the metals other than copper. The by-product revenues from zinc, gold, and silver are significant and are integral to the economics of our operations. The economics that support our decision to produce and sell copper would be different if we did not receive revenues from the other significant metals being extracted and processed. This measure provides management and investors with an indication of the minimum copper price consistent with positive operating cash flow and operating margins, assuming realized by-product metal prices are consistent with those prevailing during the reporting period. It also serves as an important operating statistic that management and investors utilize to measure our operating performance versus that of our competitors. However, it is important to understand that if by-product metal prices decline alongside copper prices, the cash cost net of by-product credits would increase, requiring a higher copper price than that reported to maintain positive cash flows and operating margins.

- Sustaining cash cost, net of by-product credits - This measure is an extension of cash cost that includes cash sustaining capital expenditures, including payments on capitalized leases, capitalized sustaining exploration, net smelter returns royalties, payments on certain long-term community agreements, as well as accretion and amortization for expected decommissioning activities for producing assets. It does not include corporate selling and administrative expenses. It provides a more fulsome measurement of the cost of sustaining production than cash cost, which is focused on operating costs only.

- All-in sustaining cash cost, net of by-product credits - This measure is an extension of sustaining cash cost that includes corporate G&A, regional costs, accretion and amortization for community agreements relating to current operations, and accretion for expected decommissioning activities for non-producing assets. Due to the inclusion of corporate selling and administrative expenses, all-in sustaining cash cost is presented on a consolidated basis only.

The tables below present a detailed build-up of cash cost and sustaining cash cost, net of by-product credits, by business unit in addition to consolidated all-in sustaining cash cost, net of by-product credits, and reconciliations between cash cost, net of by-product credits, to the most comparable IFRS measures of cost of sales for the three and six months ended June 30, 2020 and 2019. Cash cost, net of by-product credits may not calculate exactly based on amounts presented in the tables below due to rounding.

Zinc Cash Cost and Zinc Sustaining Cash Cost

Cash cost per pound of zinc produced ("zinc cash cost") is a non-IFRS measure that management uses as a key performance indicator to assess the performance of our Manitoba operations. This alternative cash cost calculation designates zinc as the primary metal of production as it is the largest component of revenues for our Manitoba business unit and should therefore be less volatile over time than Manitoba cash cost per pound of copper. The calculation is presented in three manners:

- Zinc cash cost, before by-product credits - This measure is gross of by-product revenues and is a function of the efforts and costs incurred to mine and process all ore mined. However, the measure divides this aggregate cost over only pounds of zinc produced, our primary metal of production. This measure is generally less volatile from period to period, as it is not affected by changes in the price received for by-product metals. It is, however, significantly affected by the relative mix of copper concentrate and finished zinc production, where the sale of the copper will occur later, and an increase in production of copper metal will tend to result in an increase in zinc cash cost under this measure.

- Zinc cash cost, net of by-product credits - In order to calculate the net cost to produce and sell zinc, the net of by-product credits measure subtracts the revenues realized from the sale of the metals other than zinc. The by-product revenues from copper, gold, and silver are significant and are integral to the economics of our Manitoba operation. The economics that support our decision to produce and sell zinc would be different if we did not receive revenues from the other significant metals being extracted and processed. This measure provides management and investors with an indication of the minimum zinc price consistent with positive operating cash flow and operating margins, assuming realized by-product metal prices are consistent with those prevailing during the reporting period. It also serves as an important operating statistic that management and investors utilize to measure our operating performance at our Manitoba operation versus that of our competitors. However, it is important to understand that if by-product metal prices decline alongside zinc prices, the zinc cash cost net of by-product credits would increase, requiring a higher zinc price than that reported to maintain positive cash flows and operating margins.

- Zinc sustaining cash cost, net of by-product credits - This measure is an extension of zinc cash cost that includes cash sustaining capital expenditures, capitalized exploration and net smelter returns royalties. It does not include corporate selling and administrative expenses. It provides a more fulsome measurement of the cost of sustaining production than zinc cash cost, which is focused on operating costs only.

The tables below present a detailed build-up of zinc cash cost and zinc sustaining cash cost, net of by-product credits, for the Manitoba business unit, and reconciliations between zinc cash cost, net of by-product credits, to the most comparable IFRS measures of cost of sales for the three and six months ended June 30, 2020 and 2019. Zinc cash cost, net of by-product credits, may not calculate exactly based on amounts presented in the tables below due to rounding.

Combined Unit Cost & Zinc Plant Unit Cost Reconciliation

Combined unit cost ("unit cost") and zinc plant unit cost is a non-IFRS measure that management uses as a key performance indicator to assess the performance of our mining and milling operations. Combined unit cost and zinc plant unit cost are calculated by dividing the cost of sales by mill throughput and refined zinc metal produced, respectively. This measure is utilized by management and investors to assess our cost structure and margins and compare it to similar information provided by other companies in our industry. Unlike cash cost, this measure is not impacted by variability in by-product commodity prices since there are no by-product deductions; costs associated with profit-sharing and similar costs are excluded because of their correlation to external metal prices. In addition, the unit costs are reported in the functional currency of the operation which minimizes the impact of foreign currency fluctuations. In all, the unit cost measures provide an alternative perspective on operating cost performance with minimal impact from external market prices. In the first half of 2020, as a result of the temporary suspension of operations in Peru, fixed overhead production costs incurred during the suspension were directly charged to cost of sales. These costs did not contribute to production of inventory and were therefore excluded from the calculation of combined unit costs.

The tables below present a detailed combined unit cost and zinc plant unit costs for the Manitoba business unit and combined unit cost for the Peru business unit, and reconciliations between these measures to the most comparable IFRS measures of cost of sales for the three and six months ended June 30, 2020 and 2019.

ACCOUNTING CHANGES AND CRITICAL ESTIMATES

New standards and interpretations adopted

For information on new standards and interpretations adopted, refer to note 4 of our June 30, 2020 consolidated interim financial statements.

Estimates and judgements

The preparation of the consolidated interim financial statements in conformity with IFRS requires us to make judgements, estimates and assumptions that affect the application of accounting policies, reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated interim financial statements, and reported amounts of revenue and expenses during the reporting period. Actual results may differ from these estimates.

We review these estimates and underlying assumptions on an ongoing basis based on our experience and other factors, including expectations of future events that we believe to be reasonable under the circumstances. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. Certain accounting estimates and judgements have been identified as being "critical" to the presentation of our financial condition and results of operations because they require us to make subjective and/or complex judgments about matters that are inherently uncertain; or there is a reasonable likelihood that materially different amounts could be reported under different conditions or using different assumptions and estimates.

56

For more information on judgements and estimates, refer to note 2 of our June 30, 2020 consolidated interim financial statements.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting ("ICFR"). ICFR is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS.

We did not make any changes to ICFR during the three months ended June 30, 2020 that materially affected or are reasonably likely to materially affect our ICFR.
