Hudbay Announces First Quarter 2022 Results

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. Cash 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 relative 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 sales 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 earnings ⁱ per share were $0.02.
• Operating cash flow before change in non-cash working capital was $77.1 million and adjusted EBITDA ⁱ 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 2022, 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 Snow 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 absenteeism, 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 production 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 2022 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 of 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 credits ⁱ , 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 maintained 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 continues to face intermittent operational, labour and travel disruptions with periodic waves of COVID-19 cases.

Cash generated from operating activities in the first quarter of 2022 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, first 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 $0.04, 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 remains 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 earnings ⁱ and adjusted net earnings per share ⁱ in the first quarter of 2022 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 EBITDA ⁱ was $110.2 million, compared to $180.3 million in the fourth quarter of 2021, 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 2022, 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 been 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.

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 2022, relative to the fourth quarter of 2021, 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 2022 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 2021, 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 cash cost per pound of copper produced, net of by-product credits, in the first quarter of 2022 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 contributions from precious metal by-product credits later this year.

Peru's sustaining 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.

Manitoba Operations Review

¹ Includes refined zinc metal sold and payable zinc in concentrate sold.
² Includes total payable precious metals in concentrate and in doré sold.
³ Reflects combined mine, mill and G&A costs per tonne of ore milled.
⁴ Combined unit cost, cash cost and sustaining cash cost per ounce of gold produced, net of by-product credits, are non-IFRS financial performance measures with no standardized definition under IFRS. For further information, please see the "Non-IFRS Financial Reporting Measures" section of this news release.
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 2022, the Manitoba operations produced 43,167 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%, whereas 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 months 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 2022 was lower than the fourth quarter of 2021 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 approaches 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, additions 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 commence 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 the 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 to 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.

The combined Snow Lake mills processed less ore in the first quarter compared to the fourth quarter as a result of less ore being mined at Lalor. Stall recoveries were consistent with the metallurgical model for the head grades delivered. The Flin Flon concentrator consumed the available ore feed from the 777 mine in the first quarter of 2022. Recoveries were consistent with the metallurgical model for the head grades delivered.

Combined mine, mill and G&A unit operating costs in the first quarter of 2022 increased by 5% compared to the fourth quarter of 2021. The increase was primarily due to higher propane usage during the colder winter coupled with continued inflationary cost pressures for bulk commodities and fuel, and lower tonnes processed. Full year combined unit costs are expected to remain within 2022 guidance ranges.

Cash cost per ounce of gold produced, net of by-product credits, in the first quarter of 2022 was $416 and in line with the 2022 guidance range for Manitoba.

Supply Chain and Cost Inflation

The company continues to experience higher operating costs as a result of higher input prices for many services and consumables, such as power, fuel and grinding media, due to global supply chain disruptions. Hudbay also continues to face intermittent operational labour and travel disruptions with periodic waves of COVID-19 cases. However, these external challenges are effectively being managed and Hudbay has been able to maintain steady operations during the first quarter while continuing to track in line with 2022 unit operating cost guidance.

Copper World Preliminary Economic Assessment Nearing Completion

The initial technical studies for Copper World have been completed and the results are being incorporated into a Preliminary Economic Assessment ("PEA") contemplating the development of the Copper World deposits in conjunction with an alternative plan for the Rosemont deposit to capitalize on regional synergies. The PEA is expected to incorporate a two-phase mine plan with the first phase reflecting a standalone operation utilizing Hudbay's private land for processing infrastructure and contemplating mining portions of Copper World and Rosemont located on patented mining claims. The first phase is designed as an economically viable standalone plan, requiring only state and local permits and is expected to reflect an approximate 15-year mine life.  The second phase of the mine plan is expected to extend the mine life and incorporate an expansion onto federal lands to mine the entire Rosemont and Copper World deposits. The second phase of the mine plan would be subject to the federal NEPA permitting process. Hudbay expects the PEA to demonstrate positive economics for this low-cost, long-life copper project and the company is on track to publish the results in a NI 43-101 Technical Report in the second quarter of 2022.

In April, Hudbay commenced early site works at Copper World with initial grading and clearing activities taking place on the company's private land. The company has also increased the number of drill rigs at site to seven to conduct infill drilling and to support future feasibility studies.

Rosemont / Copper World Litigation Update

In April, two groups of project opponents provided separate notices of their intent to bring citizen suits against Rosemont under the Clean Water Act. In each case, project opponents have alleged that Copper World contains jurisdictional waters of the United States ("WOTUS") and that Rosemont requires a Section 404 Clean Water Act permit to advance the project. The Army Corps of Engineers has never determined that there are WOTUS on the site and Hudbay has independently concluded that none of the dry washes in the area are WOTUS.

In addition to the citizen suits under the Clean Water Act, the same groups subsequently filed motions for a preliminary injunction in the two lawsuits challenging the 404 permit for the Rosemont project. These lawsuits had been stayed following the suspension of the 404 permit in 2019. Hudbay is in the process of relinquishing the suspended 404 Permit and has a filed a motion to dismiss these cases as moot on that basis.

Hudbay continues to await a decision from the U.S. Court of Appeals for the Ninth Circuit relating to the District Court's 2019 ruling to vacate the final record of decision ("FROD") in respect of the Rosemont project. The FROD was issued by the U.S. Forest Service and is based upon a standalone development plan for the Rosemont project, as set forth in Hudbay's 2017 feasibility study.

Mineral Reserve and Resource Growth at Constancia and Snow Lake

Hudbay provided its annual mineral reserve and resource update on March 28, 2022. In Peru, mine planning gains and economic re-evaluations have resulted in additional mineral reserves at Constancia which have largely offset 2021 mining depletion. Current mineral reserve estimates at Constancia total 521 million tonnes at 0.31% copper with over 1.6 million tonnes of contained copper. As a result, Constancia's expected mine life has been extended one year to 2038. The inferred mineral resources have also increased in 2022 due to the inclusion of the Constancia Norte underground mineral resource estimates.

In 2021, a positive scoping study was completed, which resulted in an inferred mineral resource estimate of 6.5 million tonnes at 1.2% copper in two high grade skarn lenses located below the open pit in the Constancia Norte area. The study concluded these two lenses could be mined by underground methods starting in 2029 to supplement the open pit production. The company intends to conduct infill drilling and an internal pre-feasibility study in hopes of converting the underground mineral resources to mineral reserves for inclusion in the mine plan for the Constancia operations.

As a result of exploration success in Manitoba in 2021, additional mineral reserves were identified at Lalor and the 1901 deposit, which are expected to extend the mine life of the Snow Lake operations by one year until 2038, maintaining the 17-year mine life. Resource to reserve conversion has more than offset 2021 mining depletion with a net gain for all metals, including an additional 218,000 ounces of gold contained in reserves after adjusting for 2021 mining depletion.

Inferred mineral resources at Lalor and 1901 increased by 1.1 million tonnes despite delays in underground drill programs caused by COVID-19 related restrictions. This increases the total inferred mineral resources at Lalor and 1901 to 8.1 million tonnes. These inferred mineral resources have the potential to maintain the 5,300 tonnes per day production level in Snow Lake beyond 2028 and further extend the mine life.

Other Exploration Updates

Peru Regional Exploration

Hudbay controls a large, contiguous block of mineral rights with the potential to hold mineable deposits within trucking distance of the Constancia processing facility, including the past producing Caballito property and the highly prospective Maria Reyna and Kusiorcco properties. Exploration agreement discussions with the communities of Uchucarcco and Anahuichi on the Maria Reyna, Kusiorcco and Caballito properties are in progress.

Drilling continues at the Llaguen copper porphyry target in northern Peru with a total of 9,250 metres in 21 holes completed to-date. Assays have been received for eight holes and all holes have intersected mineralization. Based on the positive results from the initial drilling, a second phase of drilling has been initiated aimed at defining an initial inferred mineral resource estimate for Llaguen in the third quarter of 2022.

Snow Lake Regional Exploration

The company has been actively conducting surface and underground winter drilling activities in the Snow Lake area, primarily focused on the copper-gold rich feeder zone at the 1901 deposit, the drilling gap between 1901 and lens 17 at Lalor, and a high-priority geophysical target located immediately north of Lalor. In addition, Hudbay continues to compile results from ongoing infill drilling programs at Lalor and 1901.

Arizona Regional Exploration

In addition to infill drilling to support feasibility studies at Copper World, Hudbay continues to test regional exploration targets. There remain several opportunities to further extend economic mineralization within the private land limits at Copper World and Rosemont, including to the north and south of Bolsa through infill drilling to bridge the gaps.

Flin Flon Tailings Reprocessing Opportunity

Hudbay is exploring the concept to potentially reprocess the Flin Flon tailings in the future. In early January 2022, the company commenced a confirmatory drill program on the tailings facility in Flin Flon to support the evaluation of the tailings reprocessing opportunity. This opportunity could utilize the Flin Flon concentrator, with modifications, after the closure of the 777 mine, creating operating and economic benefits in northern Manitoba and Saskatchewan. It could also provide the opportunity to redesign the closure plans, increase metal production, defer or reduce certain closure costs and reduce the environmental impacts of the tailings facility.

Geo, Vice President, Exploration and Technical Services. Mr. Tavchandjian is a qualified person pursuant to NI 43‑101. For a description of the key assumptions, parameters and methods used to estimate mineral reserves and resources at Hudbay's material properties, as well as data verification procedures and a general discussion of the extent to which the estimates of scientific and technical information may be affected by any known environmental, permitting, legal title, taxation, sociopolitical, marketing or other relevant factors, please see the technical reports for the company's material properties as filed by Hudbay on SEDAR at www.sedar.com .

Non-IFRS Financial Performance Measures

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 ounce of gold produced and combined 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 provides an alternate measure of the company's performance for the current period and gives insight into 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. Hudbay provides adjusted EBITDA to help users analyze the company's results and to provide additional information about its ongoing cash generating potential in order to assess its 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 its financial position. Cash cost, sustaining and all-in sustaining cash cost per pound of copper produced are shown because the company believes they help investors and management assess the performance of its operations, including the margin generated by the operations and the company. Cash cost and sustaining cash cost per ounce of gold produced are shown because the company believes they help investors and management assess the performance of its Manitoba operations. Combined unit cost is shown because Hudbay believes it helps investors and management assess the company's cost structure and margins that are not impacted by variability in by-product commodity prices.

During 2021, there were non-recurring adjustments for Manitoba operations, including severance, past service pension costs, write-downs of certain machinery and equipment, and inventory supplies write-downs as well as non-cash impairment charges related to an updated Flin Flon closure plan and lower long term discount rates in the fourth quarter, none of which management believes are indicative of ongoing operating performance and have therefore been excluded from the calculations of adjusted net earnings (loss) and adjusted EBITDA.

Cash cost and sustaining cash cost per pound of zinc produced was a previously disclosed non-IFRS measure, most recently published in the company's MD&A for the year ended December 31, 2021, dated February 23, 2022. With the planned closure of 777 mine and Flin Flon operations, including the zinc plant, in the second quarter of 2022, the production profile of Manitoba has shifted from zinc to gold and therefore the company has ceased providing this measure on a go forward basis.

The following tables provide detailed reconciliations to the most comparable IFRS measures.
