Hudbay Announces First Quarter 2022 Results

Toronto, Ontario, May 9, 2022 – Hudbay Minerals Inc. (“Hudbay” or the “ company”) (TSX, NYSE:HBM) today

released its first quarter 2022 financial results. All amounts are in U.S. dollars, unless otherwise noted.

First Quarter Operating and Financial Results

• Consolidated production in the first quarter was 24, 702 tonnes of copper and 53,956 ounces of gold. C ash

cost and sustaining cash cost i per pound of copper produced, net of by -product credits, were $1.11 and

$2.29, respectively.

• Full year 2022 production and cost guidance reaffirmed as first quarter production was in line with quarterly

cadence expectations and Hudbay achieved strong unit operating cost performance despite the inflationary

environment.

• Peru's operations in the first quarter were impacted by COVID -19 related employee absenteeism and high

rainfalls resulting in reduced Pampacancha production relati ve to the fourth quarter of 2021, as well as a

semi-annual scheduled mill maintenance period in January.

• Manitoba achieved first quarter gold production of 43,167 ounces at a cash cost per ounce of gold produced,

net of by -product credits i, of $416 as New Britannia's gold metallurgical recoveries improved significantly

relative to previous months. Manitoba sa les volumes were impacted by the availability of railcars during the

quarter, with excess inventory of approximately 7,000 tonnes of copper concentrate containing high gold

content and 6 million pounds of refined zinc at the end of the quarter, collectively valued at approximately

$45 million.

• First quarter net earnings and earnings per share were $63.8 million and $0.24, respectively. After adjusting

for a non -cash gain of $79.9 million mostly related to a quarterly revaluation of the Flin Flon environmental

provision given higher long term risk -free discount rates, amongst other items, first quarter adjusted net

earningsi per share were $0.02.

• Operating cash flow before change in non-cash working capital was $77.1 million and adjusted EBITDAi was

$110.2 million in the first quarter of 2022, benefiting from strong realized base metals prices but negatively

impacted by the temporary buildup of unsold inventory in Manitoba.

• Cash and cash equivalents decreased during the first quarter to $213.4 million, as at March 31, 2022, mainly

as a result of $55.9 million of sustaining capital investments, $31.9 million of interest payments and an $18.6

million partial repayment of the gold prepay liability, partially offset by cash generated from operations, which

was negatively impacted by limited railcar availability leading to an inventory buildup in Manitoba.

Executing on Growth Initiatives

• The Copper World preliminary economic assessment is nearing completion and is expected to reflect a two-

phase mine plan contemplating the development of the Copper World deposits in conjunction with an

alternative plan for the Rosemont deposit.

• In April 20 22, the New Britannia mill consistently achieved throughput greater than 1,500 tonnes per day

after scheduled rod mill liner maintenance was completed in the first quarter.

• Announced annual reserve and resource update with mineral reserve growth replacing close to 100% of

2021 mining depletion and extending the mine life at each of Constancia and Snow Lake by one year to

2038.

• Significant exploration activity continues across the business with seven drill rigs now turning at the Copper

World site to conduct infill and extension drilling and to support future economic studies, winter drilling

campaigns recently completed in the S now Lake region and at the Flin Flon tailings facility, and the

advancement of exploration initiatives in Peru.

“We maintained steady operations during the first quarter despite being faced with a number of external challenges,

including COVID -related abs enteeism, extreme weather conditions and inflationary cost pressures,” said Peter

Kukielski, President and Chief Executive Officer. “This led to strong unit cost performance which is a testament to our

effective risk management systems and focus on operating efficiencies. We have seen strong performance from the

New Britannia mill in Manitoba and we are on track to mine the significantly higher grades in Peru later this year . As

such, we have reaffirmed our 2022 p roduction and cost guidance . We look forward to continuing to advance our

world-class project pipeline, including the release of a robust PEA on our Copper World project in the second

quarter.”

Summary of First Quarter Results

Consolidated copper production in the first quarter of 202 2 was 24,702 tonnes, in line with expected quarterly

cadence for the year . Consolidated gold production decreased by 16% compared to the fourth quarter, primarily due

to lower gold production in Peru as COVID -19 related absenteeism and high rainfalls limited production from the

Pampacancha pit during the quarter . Consolidated zinc production in the first quarter was 4% lower than the fourth

quarter primarily due to lower zinc grades at Lalor and 777.

Consolidated cash cost per pound of copper produced, net of by -product credits i, in the first quarter of 2022 was

$1.11, compared to $ 0.51 in fourth quarter o f 2021. This increase was a result of higher milling costs and lower

copper production in Peru and higher general and administrative costs in Manitoba, partially offset by slightly higher

by-product credits per pound . Consolidated sustaining cash cost per pound of copper produced, net of by -product

creditsi, was $2.29 in the first quarter of 2022 compared to $ 1.95 in the fourth quarter. This increase was primarily

due to the same reasons outlined above , partially offset by lower sustaining capital expenditures and capitalized

exploration. Both measures were slightly above the company’s 2022 guidance ranges primarily as a result of the by-

product credit impact from lower sales volumes in the first quarter, as described below, and therefore, consolidated

cash cost and sustaining cash cost are expected to decline in future quarters to within the 2022 guidance ranges with

higher expected copper production and contributions from precious metal by-product credits.

In the first quarter of 2022, Peru and Manitoba maintain ed steady operations with unit operating cost performance of

$12.37 per tonne and C$176 per tonne, respectively, in line with the 2022 guidance ranges. This strong cost

performance was achieved despite continuing to experience broad based inflationary pressures caused by higher

input prices for many services and consumables, such as power, fuel, grinding media, freight and insurance, leading

to higher than budgeted operating costs during the first quarter of 2022. The company also continue s to face

intermittent operational, labour and travel disruptions with periodic waves of COVID-19 cases.

Cash generated from operating activities in th e first quarter of 202 2 decreased to $63.6 million compared to $ 95.8

million in the fourth quarter of 2021. Operating cash flow before change in non-cash working capital was $77.1 million

during the first quarter of 2022, compared to $156.9 million in the fourth quarter 2021. These decreases were due to

lower sales volumes for copper, gold and zinc, primarily as a result of limited railcar availability in Manitoba as

detailed below, partially offset by higher silver sales volumes and higher base metals realized prices.

As previously announced, f irst quarter Manitoba sales were impacted by limited railcar availability resulting in

approximately 7,000 tonnes of copper concentrate inventory containing high gold content , and 6 million pounds of

refined zinc inventory in excess of normal operating levels. Had the excess copper concentrate and zinc inventory

been sold during the first quarter, Hudbay would have realized approximately $ 45 million of incremental revenue,

assuming end of quarter commodity prices. The above quantities are expected to be recognized as revenue and

converted to cash as inventory levels are drawn down over the next several months with increased railcar access as

weather conditions improve.

Net earnings and earnings per share in the first quarter of 2022 were $63.8 million and $0.24, respectively, compared

to a net loss and loss per share of $10.5 million and $0.0 4, respectively, in the fourth quarter of 2021. First quarter

earnings benefited from a non -cash gain of $79.9 million mostly related to the quarterly revaluation of the Flin Flon

environmental provision, which was impacted by rising long term risk -free discount rates. With Flin Flon operations

closing in June of this year and given the long -term nature of the reclamation cash flows, quarterly revaluation of the

corresponding environmental provision remain s highly sensitive to changes in long -term risk-free discount rates and,

as such, the company expects to continue to experience quarterly environmental provision revaluations. The

quarterly financial results were also negatively impacted by $10.5 million in non-cash mark-to-market losses arising

from the revaluation of the gold prepayment liability, among other items.

Adjusted net earningsi and adjusted net earnings per sharei in the first quarter of 202 2 were $5.2 million and $0.02

per share, respectively, after adjusting for the non-cash gain related to the revaluation of the environmental provision,

among other items. This compares to an adjusted net earnings and adjusted net earnings per share of $32.7 million,

and $0.13 per share in fourth quarter of 2021. First quarter adjusted EBITDAi was $110.2 million, compared to $180.3

million in the fourth quarter of 202 1, primarily as a result of the same factors affecting operating cash flow noted

above.

As at March 31, 2022, the company’s liquidity includes $213.4 million in cash as well as undrawn availability of

$357.5 million under its revolving credit facilities. The company expects that the current liquidity combined with cash

flow from operations will be sufficient to meet its liquidity needs for the foreseeable future. Given the elevated

inventory levels in Manitoba at the end of the first quarter and the positive expected quarterly production cadence, the

company projects its cash balance to grow throughout the remainder of the year based on current commodity prices.

The Peru operations were impacted by the COVID -19 Omicron variant during January and February of 202 2,

resulting in high employee absenteeism which had a direct impact on the quarter's production. Despite the high

absenteeism, COVID-19 containment costs have decreased considerably as the severity of the variant appears lower

and COVID -19 protocols have b een modified to align with recommended public health measures. Full year

production of all metals and costs in Peru are expected to be within guidance ranges for 2022.

TSX, NYSE – HBM

During the first quarter of 2022, the Constancia operations produced 19,166 tonnes of copper, 10,789 ounces of gold,

505,568 ounces of silver and 207 tonnes of molybdenum. Production of all metals was lower than the fourth quarter

of 2021 primarily due to a planned semi -annual mill maintenance shutdown in January and lower grades . As

previously disclosed, full year production in Peru is expected to benefit from significantly higher grades in the fourth

quarter of 2022.

Total ore mined declined during the first quarter of 202 2, relative to the fourth quarter of 202 1, due to high rainfalls

and labour shortages, which resulted in delays affecting the water management system and lower production from

Pampacancha. Ore milled during the first quarter of 202 2 was lower compared to the fourth quarter of 2021 due to

the planned mill maintenance shutdown in January. Milled copper grades and recoveries were lower than the

previous quarter’s levels but were consistent with the mine plan . Milled gold grades and recoveries were lower than

the previous quarter due to a lower contribution of Pampacancha ore in the quarter.

Combined mine, mill and G&A unit operating costs in the first quarter of 2022 were $12.37 per tonne, and higher than

the fourth quarter of 202 1, primarily due to continued inflationary pressures on consumables and energy costs and

fewer tonnes of ore milled due to the planned mill maintenance shutdown. Hudbay experienced unbudgeted

inflationary pressure on costs in the first quarter of 2022 as a result of higher fuel prices, higher power prices, higher

steel prices affecting grinding media costs, higher community costs and higher insurance costs. Despite these

inflationary cost pressures, full year unit operating costs in Peru are expected to be within the 2022 guidance range.

Peru’s c ash cost per pound of copper produced, net of by -product credits, in the first quarter of 202 2 was $1.54,

higher than the fourth quarter primarily due to higher milling costs and lower copper production. Cash costs in the first

quarter were above the upper end of the 2022 guidance range in part due to lower production and higher costs

related to the scheduled semi -annual plant maintenance shutdown in the quarter. Cash cost per pound of copper

produced, net of by-product credits, is expected to decline and full year cash costs are expected to remain within the

2022 guidance range with higher expected copper production and contrib utions from precious metal by -product

credits later this year.

Peru’s s ustaining cash cost per pound of copper produced, net of by -product credits, in the first quarter of 2022

improved to $2. 27, compared to $2.46 in the fourth quarter, as lower sustaining capital expenditures and lower

capitalized exploration more than offset the higher milling costs and lower production in the quarter.

5 Cash cost and sustaining cash cost per ounce of gold produced were introduced in 2022 and do not have a published comparative.

During the first quarter of 202 2, the Manitoba operations produced 4 3,167 ounces of gold, 22,252 tonnes of zinc ,

5,536 tonnes of copper and 278,789 ounces of silver. Copper production increased by approximately 4%, where as

gold, zinc and silver production decreased by 7%, 4% and 13%, respectively, compared to the fourth quarter due to

expected grade variability quarter -to-quarter and lower ore milled . As previously mentioned, sales volumes in

Manitoba were impacted by limited railcar availability, and the resulting excess copper concentrate and refined zinc

inventory buildup is expected to normalize over the next several m onths with increased access to railcars as weather

conditions improve. Full year production of all metals and costs in Manitoba are expected to be within guidance

ranges for 2022.

Ore mined at the Manitoba operations during the first quarter of 202 2 was lower than the fourth quarter of 202 1 due

to employee absenteeism caused by COVID -19, unplanned maintenance requirements of the ore handling system

that temporarily affected hoisting ability at Lalor and planned lower production at 777 as the mine app roaches closure

in June 2022.

Lalor production processes to separate gold and base metal ores are fully established to optimally provide feed for

both the New Britannia and Stall mills based on the ore metal content. Higher gold content ore is processed at the

New Britannia facility and higher base metal content ore is directed towards Stall. A production ramp -up strategy to

achieve 5,300 tonnes per day at Lalor by the end of 2022 is underway and includes advancing development for new

mining fronts, addit ions to the mine equipment fleet, transition of workforce from the 777 mine upon closure, and

expansion of change house and office facilities. A planned Lalor maintenance period has been advanced to the

second quarter of 2022 in order to allow for increased availability during the third quarter after 777 has closed and the

additional workforce and equipment have transitioned to Lalor. The 777 equipment relocation strategy will co mmence

in the second quarter of 2022, ahead of expected timeframes to advance the production ramp -up to 5,300 tonnes per

day.

The 777 mine is within months of closure and the focus continues to be on safely mining out the remaining reserves

by completing the necessary ground rehabilitation to access remnant and pillar stoping blocks. Challenging ground

conditions continue to cause delays in the production sequence and result in higher dilution than planned. These

challenges are expected to continue until t he end of the mine life in June 2022. Pre -closure activities are well

underway in mined out areas to decommission stationary equipment of value for redeployment at Lalor. As

development requirements wind down, personnel and equipment are being redeployed t o Lalor as part of the Lalor

ramp-up strategy.

The New Britannia mill averaged approximately 1,400 tonnes per day in the first quarter of 2022 , slightly below the

targeted 1,500 tonnes per day as a result of completing scheduled rod mill liner maintenance during the quarter .

Since completing the mill maintenance, New Britannia has consistently achieved greater than 1,500 tonnes per day in

April. With the inclusion of doré, the gold and silver recoveries at the New Britannia mill have also improved

significantly with metallurgical recoveries in March higher in relation to previous months. Additional initiatives are

planned in the second quarter to further improve recoveries to be in line with metallurgical models.
