Summary:

• Operating cash flow ¹ of $124 million, a 54% increase from the first quarter 2017
• Consolidated copper production of 40,842 tonnes, an 18% increase from the first quarter 2017
• Consolidated zinc production of 34,896 tonnes, a 14% increase from the first quarter 2017
• Consolidated cash cost ² , net of by-product credits, of $0.85 per pound of copper, a 3% decrease from the first quarter 2017
• Consolidated all-in sustaining cash cost ² , net of by-product credits, of $1.49 per pound of copper, a 2% increase from the first quarter 2017
• Continued progress on reducing debt balances with $67 million repaid during the quarter and amended revolving credit facilities to extend the maturities and reduce the interest rates
• Net debt ² of $950 million and total liquidity of $497 million, including $153 million in cash, an improvement from March 31, 2017 levels of net debt of $1,035 million and total liquidity of $433 million
• Rosemont project received the Final Record of Decision from the U.S. Forest Service
• Allocated additional funds to exploration budget to focus on high-priority drilling targets
• On track to meet production, operating cost and capital cost guidance for 2017

Net profit and earnings per share in the second quarter of 2017 were $25.6 million and $0.11, respectively, compared to a net loss and loss per share of $5.7 million and $0.02, respectively, in the second quarter of 2016.

In the second quarter of 2017, operating cash flow before change in non-cash working capital increased to $124.1 million from $80.6 million in the first quarter of 2017 and $69.5 million in the second quarter of 2016. The increase in operating cash flow is the result of growth in sales volumes of most metals and higher realized copper and zinc prices.

"We continued to generate positive free cash flow, which enabled us to expand our exploration budget to focus on building our long-term growth pipeline," said Alan Hair, president and chief executive officer. "For the balance of the year, we remain committed to deliver on our operating targets, further reduce debt and advance the in-house brownfield opportunities at Lalor and Pampacancha, and we are on-track to achieve these objectives."

¹ Operating cash flow before change in non-cash working capital. ² Cash cost and all-in sustaining cash cost per pound, net of by-product credits, and net debt are not recognized under IFRS. For a detailed description of each of these non-IFRS financial performance measures used in this news release, please see the discussion under "Non-IFRS Financial Performance Measures" beginning on page 6 of this news release.

Net profit and earnings per share in the second quarter of 2017 were affected by, among other things, the following items:

Compared to the same quarter of 2016, production of zinc in concentrate increased as a result of higher zinc grades in Manitoba, while copper production declined due to lower copper grades in Peru.

In the second quarter of 2017, consolidated cash cost per pound of copper produced, net of by-product credits, was $0.85, a marginal increase compared to $0.83 in the same period of last year. Incorporating sustaining capital, capitalized exploration, royalties and corporate selling and administrative expenses, consolidated all-in sustaining cash cost per pound of copper produced, net of by-product credits, in the second quarter of 2017 was $1.49, up from $1.42 in the second quarter of 2016. The increase in all-in sustaining cash cost was driven by higher planned sustaining capital expenditures in Peru and lower copper production compared to the second quarter of 2016.

Cash and cash equivalents increased by $20.1 million in the second quarter to $152.7 million compared to March 31, 2017. This increase was partly a result of cash generated from operating activities of $131.9 million, and a net release of restricted cash of $16.9 million. These inflows were partly offset by $53.5 million of capital investments primarily at Hudbay's Peru and Manitoba operations and debt repayments of $67.1 million.

Net debt declined by $85.7 million from March 31, 2017 to $949.8 million at June 30, 2017, as approximately $63 million in drawings under Hudbay's revolving credit facilities were repaid. At June 30, 2017, total liquidity, including cash and available credit facilities, was $496.8 million, up from $432.9 million at March 31, 2017.

¹ Net debt is a non-IFRS financial performance measure with no standardized definition under IFRS. For further information, please see page 6 of this news release.

¹ Metal reported in concentrate is prior to deductions associated with smelter contract terms. ² Includes refined zinc metal sold and payable zinc in concentrate sold. ³ Cash cost, sustaining cash cost and all-in sustaining cash cost per pound of copper produced, net of by-product credits, are non-IFRS financial performance measures with no standardized definition under IFRS. For further information, please see page 6 of this news release.

Peru Operations Review

During the second quarter of 2017, the Peru operations produced 29,798 tonnes of copper, which was 10% higher than production in the first quarter 2017 as a result of improved mill throughput, but lower than production in the same quarter of 2016 due to expected grade decline as per the mine plan.

Ore mined at Constancia during the second quarter of 2017 increased by 12% compared to the same period in 2016 as the company continues to increase stockpiles to improve its ability to blend ore at the processing plant. As expected, milled copper grades in the second quarter were approximately 15% lower than the same period in 2016 as Constancia entered lower grade phases of the mine plan. Despite harder material, mill throughput improved 3% due to plant optimization initiatives during the second quarter of 2017.

Recoveries of copper, gold and silver were lower in the second quarter of 2017, compared to the same period in 2016, due to normal ore variability. Improvements in process recoveries continue to be implemented and evaluated along with consistent positive grade reconciliations.

Combined mine, mill and G&A unit operating costs in the second quarter of 2017 were 14% higher than the same period in 2016 as a result of increased unplanned plant maintenance, costs of operating the molybdenum plant at higher than planned rates, higher community spending, road maintenance costs and other administrative costs. Combined unit operating costs are expected to decline in the second half of 2017 with full year results expected to fall within the guidance range.

Cash cost per pound of copper produced, net of by-product credits, for the three months ended June 30, 2017 was $1.24, an increase of 28% from the same period in 2016 mainly as a result of decreased copper grades, together with increased plant maintenance and other costs as described above.

Sustaining cash cost per pound of copper produced, net of by-product credits, for the three months ended June 30, 2017 was $1.82, an increase of 31% from the same period in 2016 as a result of the factors noted above, as well as expected higher sustaining capital in heavy civil works during the dry season and mobile equipment overhauls.

Hudbay expects to meet production and cost guidance in Peru for the year.

Manitoba Operations Review

During the second quarter of 2017, the Manitoba operations produced 34,896 tonnes of zinc, 11,044 tonnes of copper and 26,634 ounces of gold-equivalent precious metals. Production of zinc and precious metals was higher than the same quarter in 2016 by 32% and 10%, respectively, as a result of higher grades at 777 and Lalor as well as higher production at Lalor. Production of copper during the quarter was consistent with the same period in 2016. Due to increased Lalor mine throughput and higher zinc grades at 777, zinc concentrate production is exceeding the processing capacity of the Flin Flon zinc plant. As a result, sales of excess zinc concentrate inventory began in the second quarter of 2017 and will continue as long as concentrate production exceeds zinc plant processing capacity.

Ore mined at Hudbay's Manitoba operations during the second quarter of 2017 increased by 2% compared to the same period in 2016, primarily as a result of increased production at the company's Lalor and Reed mines, partially offset by decreased production at the 777 mine. Overall zinc, gold and silver grades were 38%, 10%, and 20% higher, respectively, while copper grades were 5% lower in the second quarter of 2017 compared to the same period of 2016. Grade variances were due to planned stope sequencing, including the resequencing of the 777 mine plan to prioritize higher grade zinc stopes in 2017.

Ore processed in Flin Flon in the second quarter of 2017 was consistent with ore processed during the same period in 2016. Copper, gold and silver recoveries in the second quarter of 2017 were consistent with the same period in 2016, while zinc recovery was 10% higher due to higher zinc head grades. Unit operating costs at the Flin Flon concentrator were 6% higher in the second quarter of 2017 compared to the same period in 2016 as a result of higher maintenance expenditures. Ore processed and recoveries at the Stall concentrator in the second quarter of 2017 were consistent with the same period in 2016. Unit operating costs at the Stall concentrator were 26% higher in the second quarter of 2017 compared to the same period in 2016 as a result of higher maintenance expenditures and additional costs related to the use of higher-cost temporary crushing facilities in April. The mill resumed use of its permanent crushing circuit by the end of April 2017.

The strong ramp up of ore production from the Lalor mine in the first half of 2017 has resulted in the accumulation of an ore stockpile as Lalor's production has exceeded the Stall concentrator's current milling capacity. Hudbay has started to truck some of the stockpiled ore to the Flin Flon mill for processing in the second half of 2017.

Manitoba combined mine, mill and G&A unit operating costs in the second quarter were 25% higher than in the same period in 2016. This was partly due to higher mining unit costs at Lalor, consistent with the revised mine plan, reflecting increased cement rock filling costs as well as substantial operating and capital development work that was undertaken to support the company's plan to grow Lalor's production rates to 4,500 tonnes per day. Milling unit costs were higher for the reasons outlined above. In addition, the stockpiling of Lalor ore described above increased combined mine/mill unit costs as that metric is expressed as total costs during the period (irrespective of inventory changes), divided by the tonnes of ore milled. This factor should reverse as stockpiles reduce, although costs in the second half will be affected by higher Reed mine unit costs as the capitalization of development costs will cease, and additional costs will be incurred to truck Lalor ore to the Flin Flon mill. Processing the additional Lalor production in Flin Flon is expected to drive economies of scale and additional revenues through a faster ramp up. Combined unit costs are expected to be within the guidance range for 2017.

Cash cost, net of by-product credits, in the second quarter of 2017 was negative $0.18 per pound of copper produced compared to $0.37 in the second quarter of 2016. The decrease is primarily a result of significantly increased zinc by-product credits, partially offset by higher expected costs at the 777 and Reed mines during this part of their mine life.

Sustaining cash cost, net of by-product credits, in the second quarter of 2017 decreased to $0.38 per pound of copper produced compared to $1.10 in the second quarter of 2016 as a result of the same factors described above and lower capitalized underground mine development.

Hudbay expects to meet production and cost guidance in Manitoba for the year.

Final Record of Decision for Rosemont

On June 7, 2017, the U.S. Forest Service ("USFS") issued the Final Record of Decision ("FROD") related to the Rosemont Project. Receiving the FROD concludes a thorough process involving 17 co-operating agencies at various levels of government, 16 hearings, over 1,000 studies, and 245 days of public comment resulting in more than 36,000 comments. Since receiving the FROD, the company has commenced the administrative process working with the USFS to complete the Mine Plan of Operations ("MPO"), and the draft MPO was submitted to the USFS in late June. The other key federal permit outstanding is the Section 404 Water Permit from the U.S. Army Corps of Engineers.

Credit Facility Extension & Amendments

On July 14, 2017, Hudbay entered into amendments to its senior credit facilities to secure both facilities with substantially all of the company's assets other than assets related to the Rosemont project, amend the financial covenants, extend the maturity dates to July 14, 2021 from March 31, 2019 and reduce the interest rate to LIBOR plus 3.00% from LIBOR plus 4.50%, based on financial results for the twelve months ended June 30, 2017. The revised covenants include maintaining gross total debt to EBITDA of less than 4.00 times in 2017, senior secured debt to EBITDA of less than 2.00 times, and interest coverage of more than 3.00 times. The two facilities have substantially similar terms and conditions and continue to provide revolving credit to a maximum amount of up to $550 million.

Exploration Update

Given the strong free cash flow generation of the business year-to-date, additional funds have been allocated to exploration in 2017 with a focus on high-priority drilling targets. The company has been active in identifying and acquiring grassroots exploration properties in Peru, Chile and British Columbia during the recent downturn in metals prices. The increase in exploration expenditures is expected to fund drilling on the grassroots exploration properties, as well as testing targets in Manitoba and drilling down plunge at Lalor.

The revised exploration guidance for 2017 is shown below:

¹ Assumes $2 million of Manitoba expenditures will be capitalized.

Dividend Declared

A semi-annual dividend of C$0.01 per share was declared on August 3, 2017. The dividend will be paid on September 29, 2017 to shareholders of record as of September 8, 2017.

Non-IFRS Financial Performance Measures

Net debt is shown in this news release 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. 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. For further details on these measures, including reconciliations to the most comparable IFRS measures, please refer to page 31 of Hudbay's management's discussion and analysis for the three and six months ended June 30, 2017 available on SEDAR at www.sedar.com and EDGAR at www.sec.gov .
