Hudbay Announces Fourth Quarter and Full Year 2021 Results and Provides

Annual Guidance

Toronto, Ontario, February 23, 2022 – Hudbay Minerals Inc. (“Hudbay” or the “ company”) (TSX, NYSE:HBM)

today released its fourth quarter and full year 2021 financial results and annual production and cost guidance. All

amounts are in U.S. dollars, unless otherwise noted.

Fourth Quarter and Full Year Operating and Financial Results

• Consolidated copper production of 99,470 tonnes and consolidated gold production of 193,783 ounces

increased by 4% and 55%, respectively, in 2021 as compared to 2020.

• Achieved 2021 consolidated copper, gold and silver production guidance while zinc produc tion fell short of

the 2021 guidance range.

• Peru copper production met 2021 guidance with strong operating performance in the fourth quarter, aided by

the continued ramp up of Pampacancha. Manitoba zinc production wa s below 2021 guidance primarily due

to higher dilution and mine plan limitations at the 777 mine as it approaches closure.

• Record quarterly consolidated gold production of 64,159 ounces in the fourth quarter, an increase of 18%

compared to the third quarter of 2021, due to higher grades at Pampacancha and the commissioning of the

New Britannia mill.

• Generated record quarterly revenue of $425.2 million. Operating cash flow before change in non -cash

working capital was $156.9 million and adjusted EBITDA i was $180.3 million in the fourth quarter of 2021,

due to higher realized base metals prices and higher gold and coppe r sales volumes, partially offset by

lower zinc sales volumes.

• Full year, consolidated cash cost and sustaining cash cost per pound of copper produced, net of by -product

creditsi, of $0.74 and $2.07, respectively, achieved 2021 guidance as inflationary cos t pressures were offset

by strong by-product credits.

• Consolidated cash cost and sustaining cash cost per pound of copper produced, net of by -product creditsi,

for the fourth quarter of 2021 were $0.51 and $1.95, respectively, a decrease of 18% and an increase of 1%,

respectively, compared to the third quarter of 2021.

• Fourth quarter net loss and loss per share were $10.5 million and $0.04, respectively. After adjusting for an

impairment charge related to a revaluation of our Flin Flon environmental obligat ion due to declining long

term discount rates, amongst other items, fourth quarter adjusted net earningsi per share was $0.13.

Executing on Growth Initiatives

• New Britannia achieved commercial production on November 30, 2021. December mill throughput averaged

1,200 tonnes per day with gold and silver recoveries in line with metallurgical models . Throughput and

recoveries are expected to achieve design rates in the second quarter of 2022.

• Published an initial mineral resource estimate for Copper World on December 15, 2021, which contained a

higher grade, near-surface zone that has the potential to be mined earlier in the mine life and is composed

of both sulphide and oxide mineralogy. The company remains on track to complete a preliminary economic

assessment of Copper World in the first half of 2022.

• Results from the Constancia Norte underground scoping study are expected to be incorporated into the

annual mineral reserve and resource update for Constancia in March 2022.

• Commenced a winter drilling program in Manitoba in January 2022 to test high -priority targets near Lalor

and 1901 for potential reserve and resource expansion and support the completion of a preliminary

economic assessment of the Flin Flon tailings reprocessing opportunity.

“2021 was a year of execution for Hudbay as we invested approximately $250 million in our brownfield growth

projects at Pampacancha and New Britannia,” said Peter Kukielski, President and Chief Executive Officer. “We began

to see increased cash flows from these short -payback, high-return investments in the fourth quarter and we are now

at an inflection point where we anticipate meaningful copper and gold production growth along with significant

EBITDA and cash flow growth. 2022 will be a year in which we start to reap the rewards from our disciplined growth

strategy while we advance our high-quality pipeline of copper growth assets, including our newly discovered Copper

World project in Arizona, which we believe will generate significant value.”

2022 Annual Guidance and Outlook

• Consolidated copper production is forecast to increase by 17% to 116,000 ii tonnes in 2022 and by 34% to

133,500ii tonnes in 2024, compared to 2021, with higher copper grades expected from the Pampacancha

deposit in Peru.

• Consolidated gold production is forecast to increase by 2 8% to 24 7,500ii ounces in 2022 and by 59% to

307,500ii ounces in 2024, compared to 2021 , due to higher production from the New Britannia mill and

Pampacancha.

• Introduced 2022 cash cost guidance by business unit with Peru cash cost of $ 1.10 to $1.40 per pound of

copper produced, net of by -product credits i, and Manitoba cash cost of $ 300 to $550 per ounce of gold

produced, net of by-product creditsi.

• 2022 unit operating costs are expected to increase by approximately 7%ii in Peru and 15% ii in Manitoba,

compared to 2021, as a result of expected higher input costs due to industry wide inflation in each region

and the transition of operations in Manitoba.

• Consolidated cash cost guidance of $0.60 to $1.05 and consolidated sustaining cash cost guidance of $1.60

to $2.25, in each case, per pound of copper produced, net of by-product credits, is expected in 2022.

• Total capital expenditures are expected to decline by 17% year -over-year as major growth investment

programs in Peru and Manitoba were completed in 2021 and lower sustaining capital spending is expected

in Peru, offset by higher growth spending on technical and economic studies for Copper World.

• Exploration spending of approximately $65.0 million in 2022 reflects plans to continue drilling activities at

Copper World and test promising targets in Peru, Manitoba, Nevada and Chile.

Summary of Fourth Quarter Results

Consolidated copper production in the fourth quarter of 2021 was 2 8,198 tonnes, a 21% increase compared to the

third quarter of 2021, primarily due to higher throughput and copper grades in Peru . Consolidated gold product ion

was 64,159 ounces in the fourth quarter of 2021, another quarterly record for Hudbay and an increase of 18% versus

the third quarter , primarily due to higher gold production in Snow Lake with the commissioning of the New Britannia

mill in the fourth quarter. Consolidated zinc production in the quarter increased by 11% versus the third quarter of

2021, primarily due to higher zinc grades at 777 and Lalor . Consolidated silver production in the fourth quarter

increased by 18% compared to the third quarter as higher grades and recoveries in Manitoba offset lower grades in

Peru.

In the fourth quarter of 2021, consolidated cash cost per pound of copper produced, net of by -product creditsi, was

$0.51, compared to $0.62 in the third quarter of 2021. This 18% decrease was mainly a result of higher copper

production and higher gold by -product revenue. Sustaining cash cost per pound of copper produced, net of by -

product creditsi, slightly decreased to $1.95 in the fourth quarter of 2021, from $1.97 in the third quarter, primarily due

to the same factors affecting cash cost offset by higher sustaining capital expenditures and royalties.

Operating cash flow before change in non -cash working capital was $156.9 million during the fourth quarter of 2021,

reflecting an increase of $53.4 million compared to the third quarter of 2021 , primarily the result of higher realized

base metal prices and higher gold and copper sales volumes.

Net loss and net loss per share in the fourth quarter of 2021 were $10.5 million and $0.04, respectively, compared to

a net loss and net loss per share of $170.4 million and $0.65, respectively, in the third quarter of 2021. Fourth quarter

results were negatively impacted by a revaluation of the environmental obligation due to lower long term discount

rates since the middle of the year and a corresponding increase to Flin Flon’s property plant and equipment

("PP&E"). As the closure of the 777 mine and Flin Flon operations is expected to commence within several months,

an impairment charge was made to PP&E resulting in a loss of $46.2 million. The quarterly financial results were also

negatively impacted by $13.3 million in mark-to-market net losses arising from the revaluation of the gold prepayment

liability, revaluation of certain ot her financial instruments, share -based compensation, and a $3. 4 million Flin Flon

restructuring charge.

Adjusted net earningsi and adjusted net earnings per sharei in the fourth quarter of 2021 were $32.7 million and $0.13

per share , respectively, after adjusting for the impairment charge related to the revaluation of the environmental

obligation in Flin Flon, among other items. This compares to adjusted net earnings and adjusted net earnings per

share of $0.9 million and $0.00 per share in the third quarter of 202 1, which were recalculated as a result of the

company’s year-end 2021 tax provision calculation review (see “Non-IFRS Financial Performance Measures”). Fourth

quarter adjusted EBITDA i increased to $180.3 million, compared to $ 119.3 million in the third quarter of 202 1,

primarily due to higher copper and gold sales volumes and higher realized prices, partially offset by higher exploration

and selling and administrative expenses.

As at December 31, 2021, Hudbay’s liquidity includes $271.0 million in cash and cash equivalents as well as undrawn

availability of $346.9 million under its revolving credit facilities. The company’s liquidity position was further enhanced

in October 2021 through the renegotiation of its credit facilities to increase available borrowings to $450 .0 million and

extend the maturity to 2025.

Summary of Full Year Results

On a consolidated basis, Hudbay’s copper, gold and silver production met 2021 guidance; however, production of

zinc and molybdenum fell short of the 2021 guidance ranges. Production of gold in Peru exceeded the top end of the

guidance range due to strong gold grades from Pampacancha. Prod uction of gold and silver in Manitoba fell below

the 2021 guidance range primarily due to higher than expected grade dilution at the 777 mine during the fourth

quarter and prioritizing base metal rich zones in the fourth quarter at Lalor while deferring some gold-rich ore for

future processing at New Britannia to achieve higher gold recoveries. Zinc production was impacted by higher dilution

and mine plan limitations as the 777 mine approaches the end of life.

Consolidated cash costs per pound of copper produced, net of by -product creditsi, for 2021 was $0.74, and

consolidated sustaining cash cost per pound of copper produced, net of by -product credits i, for 2021 was $2.07, in

line with the company’s 2021 guidance range.

Operating cash flow before change in non ‑cash working capital increased to $483.9 million from $241.9 million in

2020. The increase is the result of higher realized base metal and molybdenum prices and higher sales volumes of

gold and copper, partially offset by lower zinc sales volumes.

Net loss and loss per share for 2021 were $244.4 million and $0.93, respectively, compared to a net loss and loss per

share of $144.6 million and $0.55, respectively, in 2020. Contributing to the 2021 net loss was an impairment charge

of $193.5 million related to an updated closure plan reflecting higher estimates for closure activities in Flin Flon. Full

year results were also negatively impacted by charges related to the refinancing of the 2025 senior notes, including a

write off of the non -cash embedded derivative of $49.8 million connected with the exercise of the redemption option

and a call premium payment of $22.9 million, as well as a $12.4 million Flin Flon restructuring charge.

Peru has experienced notable improvements in COVID -19 health statistics throughout 2021. Peru operations did not

encounter any major COVID -19 interruptions during the year; however, with the recent emergence of the Omicron

variant in Peru, the company has continued to maintain stringent COVID -19 measures and controls to ensure the

safety of Hudbay’s workforce and this has contributed to elevated unit operating costs.

During the fourth quarter of 2021, the Constancia operations produced 22,856 tonnes of copper, 17,917 ounces of

gold, 578,140 ounces of silver and 275 tonnes of molybdenum. Copper production was 26% higher than the third

quarter due to an increase in throughput and recovery at both Constancia and Pampacancha. Gold and silver

production increased by 2% and 11%, respectively, due to the increased throughput and higher grades . This was

another record quarter for gold production in Peru.

Full year 2021 copper production increased by 6% year -over-year to 77,813 tonnes, within the annual guidance

range. Full year 2021 gold production increased by 306% year -over-year to 50,306 ounces and exceeded the 2021

guidance range due to increased throughput, higher grades from Pampacancha and higher gold recoveries. Full year

2021 production guidance was met for all metals except molybdenum, which was in line with the mine plan published

in March 2021.

Total ore mined during the fourth quarter of 2021 increased by 19% from the third quarter of 202 1 as mining levels

were optimized for mill throughput . Ore mined at Pampacancha in 2021 was 5.1 million tonnes, exceeding the four

million tonne threshold required to receive an additional $4 m illion deposit from Wheaton Precious Metals under the

amended Constancia streaming agreement. The proceeds of this deposit were received in December 2021 and were

accounted for as an increase in the deferred revenue balance.

Ore milled during the fourth quarter of 2021 was 15% higher than the previous quarter due to a scheduled semi -

annual mill maintenance program affecting third quarter ore milled . Milled grades for copper were higher than the

third quarter due to higher grades from the Constancia pit. Milled grades for gold were consistent with the most recent

quarter, while milled silver grades were lower but consistent with the mine plan.

Copper recoveries in the fourth quarter increased over the third quarter of 2021 due to lower oxide levels in the

Constancia ore. Recoveries of gold in the fourth quarter of 2021 were lower than the third quarter due to variability of

the Pampacancha volume being treated and the increased presence of zinc, while silver recoveries slightly increased

compared to the third quarter due to variable metallurgical characteristics of the earlier ores from Pampacancha and

slightly lower silver head grades.

Combined mine, mill and G&A unit operating costs in the fourth quarter of 202 1 were $10.47 per tonne , a 10%

improvement versus the third quarter of 2021. COVID-related costs in Peru were $4.1 million in the fourth quarter of

2021. Combined unit operating costs in the fourth quarter were $9.96 per tonne excluding these COVID-related costs.

Full year combined unit operating costs were 20% higher than the same period in 2020 due to inflationary pressures

on consumables and energy costs and higher COVID-19 expenditures, offset in part by additional tonnes milled.

Peru’s cash cost per pound of copper produced, net of by -product credits, in the fourth quarter of 202 1 was $1.28,

relatively in line with the prior quarter. Peru’s sustaining cash cost per pound of copper produced, net of by -product

credits, in the fourth quarter of 2021 increased to $2.46, compared to $2.31 in the third quarter of 2021, due to higher

capitalized expenditures, partially offset by higher copper production.
