Hudbay Announces Third Quarter 2021 Results

Toronto, Ontario, November 3, 2021 – Hudbay Minerals Inc. (“Hudbay” or the “ company”) (TSX, NYSE:HBM)

today released its third quarter 2021 financial results. All amounts are in U.S. dollars, unless otherwise noted.

Third Quarter Operating and Financial Results

• Generated $359.0 million in revenue, $103.5 million of operating cash flow before change in non -cash

working capital and $119.3 million of adjusted EBITDAi in the third quarter of 2021 from higher realized base

metals prices and higher gold sales volumes, partially offset by lower base metals sales volumes.

• Consolidated copper production in the third quarter was 23,245 tonnes ; quarterly c onsolidated gold

production increased by 35% to 53,872 ounces in the third quarter, compared to the second quarter in 2021,

a record for Hudbay.

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

were $0.62 and $1.97, respectively , an improvement of 26% and 12% compared to the second quarter of

2021.

• Third quarter Peru production was boosted by significantly higher gold grades from Pampacancha and

record gold recoveries, leading to record quarterly go ld revenue. Pampacancha production continues to

ramp-up, achieving a 109% increase in ore production quarter over quarter.

• Third quarter Manitoba production benefited from higher throughput and higher gold grades at Lalor but was

negatively impacted by lo wer zinc grades and zinc recoveries, limiting overall zinc concentrate feed to the

zinc plant. Manitoba results included initial gold production from New Britannia's gold circuit.

• On track to meet annual production guidance for copper, gold, zinc and silver in concentrate and doré,

consolidated sustaining capital expenditures, and Manitoba unit operating cost in 2021. After adjusting for

unbudgeted COVID-related costs in Peru, full year unit operating costs for Peru are expected to be around

the top end of the 2021 guidance range.

• Third quarter net loss and loss per share were $17 0.4 million and $0.65, respectively. After normalizing for

an impairment charge related to higher estimated closure costs associated with the company’s updated Flin

Flon closure p lan and the Flin Flon restructuring charges, amongst other items, third quarter adjusted net

earningsi per share were $0.15.

• Cash and cash equivalents increased during the third quarter to $297.5 million as at September 30, 2021,

mainly as a result of $139.8 million of cash generated from operations, partially offset by $89.1 million of

capital investments primarily for the cons truction of the New Britannia project and sustaining capital

expenditures, and $33.6 million of interest paid on the company’s senior unsecured notes.

Executing on Growth Initiatives

• New Britannia has achieved project completion as construction activities at the new copper flotation facility

concluded in October. Refurbishment and commissioning activities at the gold mill were completed in July

2021, and the mill achieved first gold production on August 11, 2021. Commissioning of the copper circuit

was completed and first production of concentrate was achieved in October, ahead of the original schedule ,

while ramp-up activities at the flotation plant continue. Annual gold production from Lalor and the Snow Lake

operations is on track to increase to over 180,000 ounces at an average cash cost and sustaining cash cost,

net of by -product credits, of $412 and $788 per ounce of gold, respectively, during the first six full years of

operation starting in 2022.

• Mining activities at the Pampacancha satellite pit continue to advance as planned with grades and tonnes

reconciling well against the mine plan, achieving the expected increase in gold grades in 2021 and on track

for achieving higher copper grades in 2022, in line with recent company guidance.

• Recent Copper World drilling has identified three new deposits for a total of seven distinct deposits with a

combined strike length of over seven kilometres. The company remains on track to complete an initial

inferred resource estimate before the end of the year and a preliminary economic assessment in the first half

of 2022.

• Scoping study planned for 2022 to examine the opportunity to reprocess tailings in Flin Flon after the closure

of the 777 mine, which could further increase metal production, defer closure costs and reduce the

environmental footprint of the tailings facility.

• Amended and restated Hudbay’s senior secured revolving credit facilities to increase available borrowings to

$450 million and enhance the company’s financial flexibility, while extending the maturity to 2025.

“Our third quarter performance demonstrates our continued focus on execution and delivery in 2021 as we enjoyed

the first full quarter of Pampacancha production and we started to see the benefits of higher gold from the New

Britannia mill,” said Peter Kukielski, President and Chief Executive Officer. “We also recently commissioned the new

copper flotation circuit at New Britannia, ahead of our expected timelines. With the completion of the Pampacancha

and New Britannia growth projects , we are on the cusp of achieving significantly increased cash flows from these

high-return investments for many years to come . We are also very pleased to have continued exploration success at

our Copper World project and look forward to advancing the opportunity for a private land operation in Arizona to

unlock further value for our stakeholders.”

Summary of Third Quarter Results

Cash generated from operating activities in the third quarter of 2021 increased to $139.8 million, compared to $96.4

million in the second quarter and $51.8 million in the first quarter of 2021. Operating cash flow before change in non -

cash working capital was $103.5 million during the third quarter of 2021, reflecting a decrease of $ 29.3 million

compared to the second quarter of 2021, primarily as a result of lower base metals sales volumes and lower realized

copper and precious metals prices, partially offset by higher precious metals sales volumes.

Consolidated copper production in the third quarter of 202 1 was 23,245 tonnes, generally in-line with the second

quarter of 2021 as slightly lower copper production in Peru was offset by higher copper production in Manitoba .

Consolidated gold production in the third quarter of 2021 was 53,872 ounces, a quarterly record for Hudbay and a

35% increase from the second quarter of 2021 , due to higher gold grades from Pampacancha and record gold

recoveries in Peru, along with significantly higher gold grades at Lalor . Zinc production in the quarter was 20,844

tonnes, a slight decrease from the second quarter as production volumes were lower in Flin Flon. Consolidated silver

production increased to 763,168 ounces, an 11% increase versus the second quarter of 2021, primarily due to higher

silver grades milled in Peru and Snow Lake.

In the third quarter of 2021, consolidated cash cost per pound of copper produced, net of by -product credits i, was

$0.62, compared to $ 0.84 in the second quarter of 2021. This 26% decrease was mainly a result of lower operating

costs. Sustaining cash cost per pound of copper produced, net of by -product creditsi, decreased to $1.97 in the third

quarter of 2021, from $2. 25 in the second quarter, primarily due to the same factors affecting cash cost as well as

slightly lower sustaining capital expenditures . Consolidated cash cost and sustaining cash cost per pound of copper

produced, net of by-product credits, are expected to remain within the guidance ranges for 2021.

Net loss and loss per share in the third quarter of 202 1 were $170.4 million and $0. 65, respectively, compared to a

net loss and loss per share of $3.4 million and $0. 01, respectively, in the second quarter of 2021. Third quarter

results were negatively impacted by an updated closure plan reflecting higher estimates for closure activities in Flin

Flon, primarily related to water treatment costs . The higher closure cost estimate has resulted in an increase to the

company’s environmental obligation and a corresponding increase to Flin Flon’s property plant and equipment.

However, as the closure of Flin Flon is expected to commence within 12 months, an impairment charge was made

resulting in a loss of $147.3 million. The quar terly financial results were also negatively impacted by Flin Flon

restructuring charges comprising an inventory supplies write down of $5.4 millio n and a severance accrual of $3.6

million for unionized employees , as well as an increase in past service pension cost provision of $4. 2 million related

to pensions for Manitoba unionized employees.

Adjusted net earningsi and adjusted net earnings per sharei in the third quarter of 2021 were $ 38.2 million and $0.15

per share after normalizing for an impairment due to the updated Flin Flon closure plan and the Flin Flon restructuring

charges, among other items . This compares to adjusted net earnings and adjusted net earnings per share of $5.4

million and $0.02 per share in the second quarter of 202 1. Third quarter adjusted EBITDA i was $1 19.3 million,

compared to $143.2 million in the second quarter of 2021, primarily due to lower base metal sales volumes and lower

realized copper and precious metals prices, partially offset by higher precious metals sales volumes.

As at September 30, 2021, Hudbay’s liquidity includes $29 7.5 million in cash and cash equivalents as well as

undrawn availability of $297.3 million under its credit facilities. The company’s liquidity position was further enhanced

in October through the successful renegotiation of the credit facilities to increase available borrowings to $450 million,

while extending the maturity to 2025.

While Peru has experienced notable improvements in COVID -19 statistics throughout 2021, Hudbay continues to

maintain stringent COVID -19 measures and controls to ensure the safety of its workforce, partners and the

communities in which the company operates. This has allowed Constancia to continue to operate safely although it

has resulted in elevated unit operating costs due to the ongoing COVID-related protocols.

During the third quarter 2021, the Constancia operations produced 18,072 tonnes of copper, 17,531 ounces of gold,

521,036 ounces of silver and 282 tonnes of molybdenum. While copper production was 5% lower than the second

quarter due to a planned semi -annual mill maintenance shutdown in July , gold and silver production increased by

72% and 11%, respectively, due to significantly higher gold and silver head grades from Pampacancha and

significantly higher gold recoveries. This was a record quarter for gold production, grade s and recoveries in Peru.

Other than molybdenum, which is expected to fall slightly below the 2021 guidance range but in-line with the recently

published mine plan , Hudbay expects the production of all other metals in Peru to be in line with the 2021 full year

guidance.

Total ore mined during the third quarter of 2021 decreased by 8% from the second quarter of 2021 as mining levels

were optimized for mill throughput . Ramp-up of mining activity at Pampacancha has increased steadily since first

production in April 2021. Total Pampacancha ore mined during the third quarter increased by 109% to 2.1 million

tonnes compared to the second quarter of 2021. Tonnes of ore milled during the third quarter of 2021 were 6% lower

than the second quarter of 2021 due to the scheduled mill mai ntenance shutdown. Milled grades for copper were

slightly lower than the second quarter but were in line with the mine plan . Milled grades for gold and silver were 57%

and 36% higher, respectively, than the second quarter due to significantly higher precio us metal head grades from

Pampacancha.

Peru achieved record gold recoveries in the third quarter of 2021, significantly above the second quarter of 2021 ,

mainly due to higher grades from Pampacancha . Meanwhile, copper recoveries increased due to lower levels of

contaminants and silver recoveries decreased as a result of lower -than-expected recoverable silver values in the

earlier, more oxidized ores from Pampacancha. Recent metallurgical test work in dicates that Pampacancha silver

recoveries are expected to increase to targeted levels in 2022.

Combined mine, mill and G&A unit operating costs in the third quarter of 2021 were $11.62 per tonne, compared to

$11.25 in the second quarter of 202 1, primarily due to higher milling costs and fewer tonnes milled due to the

scheduled mill maintenance program during the quarter . Costs have been generally higher in 2021 as a result of

higher ore hardness, higher steel prices affecting grinding media costs, higher fuel prices impacting hauling costs and

COVID-19 expenditures. COVID-related costs in Peru were $4.8 million in the third quarter and are expected to

continue at a similar run-rate into the fourth quarter of 2021. Unit operating costs in the third quarter were $10.93 per

tonne excluding these COVID-related costs. Hudbay expects Peru unit operating costs to be around the top end of

the 2021 guidance range after adjusting for unbudgeted COVID-related costs.

Peru’s cash cost per pound of copper produced, net of by -product credits, in the third quarter of 202 1 was $1.26, a

32% improvement over the second quarter . The significant reduction in cash cost was due to higher by -product

credits and lower operating costs, partially offset by lower copper production. Peru’s sustaining cash cost per pound

of copper produced, net of by-product credits, in the third quarter of 2021 decreased to $2.31, compared to $2.69 in

the second quarter of 2021, due to same factors noted above affecting cash costs, offset by higher sustaining capital

expenditures.

As the Manitoba business started to see the benefits from the commencement of gold production at the New

Britannia mill, production of copper, gold and silver increased during the third quarter, compared to the second

quarter of 2021, while production of zinc decreased . Production during the quarter included 5,173 tonnes of copper,

36,745 ounces of gold, 242,141 ounces of silver and 20,844 tonnes of zinc . Hudbay expects the production of all

metals contained in concentrate and doré in Manitoba to be in line with the 2021 full year guidance.

Mining operations at Lalor have started to consistently produce and separate the gold and copper -gold ores as feed

for the New Britannia mill. At the end of the third quarter of 2021, approximately 35,000 tonnes of gold ore is

stockpiled as feed for New Br itannia, a decrease of approximately 12,000 tonnes from the end of the second quarter

of 2021. The 777 mine is now within nine months of closure and the focus continues to be on mining out the

remaining reserves by completing the necessary ground rehabilit ation in order to access old workings and remnant

stopes.

Ore mined at the Manitoba operations during the third quarter of 2021 was higher than the second quarter of 202 1

due to higher production rates at Lalor . Copper and g old grades were higher compared to the previous quarter,

mainly due to increased mining of gold and copper -gold stopes at Lalor, in line with the mine plan. Mined zinc grades

were lower than the previous quarter as mining of the gold zones at Lalor were prioritized during the quarter.

During the third quarter of 2021, New Britannia processed 41,827 tonnes of high gold content ore and produced 404

ounces of gold in doré after pouring its first doré bar on August 11. The gold and silver recoveries are expect ed to

increase in the fourth quarter after ramp -up of the mill during the third quarter. Construction of the new copper

flotation circuit was completed in October 2021 , followed by a brief commissioning period completed ahead of

schedule. Ramp-up activities at the copper circuit are underway and are on track for completion in the fourth quarter

of 2021.

Ore processed at the Stall concentrator and New Britannia mill during the third quarter was 29% higher than the

second quarter. Combined Stall and New Britannia recoveries during the third quarter of 2021 were higher for zinc

and lower for copper, gold and silver, versus the previous quarter, but were consistent with expectations as the third

quarter was a partial ramp -up period for the New Britannia mill . Operations at the Flin Flon concentrator during the

third quarter were constrained by ore feed availability from 777 and, as such, ore processed decreased by 22%

compared to the second quarter of 2021. Recoveries of copper, gold and silver at the Flin Flon concentrator during

the second quarter of 2021 were higher than the previous quarter mainly due to higher copper head grades from the

777 mine, consistent with the metallurgical model.

Combined mine, mill and G&A unit operating costs in the third quarter of 2021 slightly decreased compared to the

second quarter of 2021. Hudbay expects Manitoba unit operating costs in 2021 to be in line with the annual guidance

range.

Manitoba’s cash cost per pound of copper produced, net of by -product credits, for the third quarter of 202 1 was

negative $ 1.64, higher than the second quarter primarily due to lower by -product credits, partially offset by lower

onsite costs. Manitoba’s sustaining cash cost per pound of copper produced, net of by -product credits, in the third

quarter of 2021 was $0.75 compared to $0.36 in the second quarter, primarily due to the same reasons listed above,

offset by lower comparative sustaining capital expenditures.
