Hudbay Announces Second Quarter 2018 Results

TORONTO, July 31, 2018 -- HudBay Minerals Inc. (“Hudbay” or the “company”) (TSX:HBM) (NYSE:HBM) today released its second quarter 2018 financial results. All amounts are in U.S. dollars, unless otherwise noted.

Summary:

• Net profit and earnings per share in the second quarter of 2018 were $25 million and $0.09, respectively, compared to a net profit and earnings per share of $19 million and $0.08, respectively, in the second quarter of 2017
• Operating cash flow¹ of $132 million in the second quarter of 2018, a 6% increase from the second quarter of 2017
• Reduced net debt² position by $49 million during the second quarter of 2018; as at June 30, 2018, Hudbay had net debt of $536 million and total liquidity, including cash and available credit facilities, of $859 million
• Consolidated cash cost², net of by-product credits, of $0.96 per pound of copper, a 13% increase from the second quarter of 2017
• Consolidated all-in sustaining cash cost², net of by-product credits, of $1.48 per pound of copper in the second quarter of 2018, down slightly from $1.49 in the second quarter of 2017
• Manitoba combined mine/mill unit operating costs are now expected to be between C$125 and C$135 per tonne in 2018³; Peru remains on track to meet production, capital cost and unit cost guidance for 2018

Net profit and earnings per share in the second quarter of 2018 were $24.7 million and $0.09, respectively, compared to a net profit and earnings per share of $19.1 million and $0.08, respectively, in the second quarter of 2017.

In the second quarter of 2018, operating cash flow before change in non-cash working capital increased to $131.6 million from $124.1 million in the same quarter of 2017. The increase in operating cash flow is the result of higher realized prices for copper, zinc and precious metals, partially offset by decreases in the sales volumes of copper, zinc and silver and higher mine operating costs.

“In the first half of the year, we delivered solid production results and growing free cash flow, and applied that cash flow to substantial net debt reduction and funding the development of our exploration pipeline,” said Alan Hair, president and chief executive officer. “Our focus for the remainder of the year is to deliver on our operating targets, complete the ramp-up of ore production at Lalor and move Rosemont through the permitting process into development.”

Net profit and earnings per share in the second quarter of 2018 were affected by, among other things, the following items:

Compared to the second quarter of 2017, production of contained copper-equivalent in concentrate in the second quarter of 2018 decreased by 6.7% as a result of lower production of copper and zinc, partially offset by higher production of precious metals. This reflected lower grades at the Constancia mine in accordance with the mine plan, offset in part by higher Constancia mill throughput.

In the second quarter of 2018, consolidated cash cost per pound of copper produced, net of by-product credits, was $0.96, an increase compared to $0.85 in the same period last year. The increase is mainly due to increased operating costs in Hudbay’s Peru and Manitoba business units and reduced copper production, partially offset by higher by-product credits realized. 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 2018 was $1.48, down slightly from $1.49 in the second quarter of 2017, as higher cash costs were offset by reduced sustaining capital spending.

Cash and cash equivalents increased by $46.8 million from March 31, 2018 to $439.6 million as at June 30, 2018. This increase was a result of operating cash flow before change in non-cash working capital of $131.6 million. These inflows were partly offset by $34.6 million of working capital movements and $39.2 million of capital investments, primarily at Hudbay’s Peru and Manitoba operations.

Net debt declined by $49.2 million from the first quarter to $536.2 million at June 30, 2018, as a result of positive cash flow from Hudbay’s operations. At June 30, 2018, total liquidity, including cash and available credit facilities, was $859.2 million, up from $810.0 million at March 31, 2018.

Based on results to date, Hudbay is on track to meet production and capital expenditure guidance expectations, as well as Peru unit cost guidance. As a result of a number of factors, including cold weather in the first quarter, higher costs at the 777 mine and the impact of a fan outage at the Lalor mine, Hudbay expects Manitoba combined mine/mill unit operating costs to be between C$125 and C$135 per tonne in 2018.

Peru Operations Review

During the second quarter of 2018, the Peru operations produced 26,818 tonnes of copper, which was approximately 10% lower than production in the second quarter of 2017 due to an expected decline in mined grades in accordance with the mine plan. Production for the first half of 2018 for all commodities increased compared to the same period in 2017 due to improved mill throughput, offset in part by lower copper grades.

Recoveries of copper and silver were slightly lower in the second quarter of 2018, compared to the same period in 2017, while gold recoveries remain unchanged over the same period. Hudbay is implementing several metallurgical initiatives with the intention of increasing copper recoveries as anticipated in the recently filed 2018 Technical Report for Constancia. Production results to date are on track to meet 2018 Peru production guidance.

Combined mine, mill and G&A unit operating costs in the second quarter of 2018 were 15% higher than the same period in 2017. The higher combined unit operating costs are due to higher costs for diesel, steel and power and a decrease in capitalized stripping. Combined unit costs for the first half of 2018 include accruals for signing bonuses for the three-year collective bargaining agreement agreed to earlier in 2018, as well as costs associated with the scheduled plant maintenance outage in May 2018, which was significantly broader in scope than the maintenance planned for the fourth quarter of 2018. Accordingly, Hudbay expects combined unit costs in the second half of 2018 to be lower than the first half, with full year combined unit costs expected to be within the guidance range for 2018.

Cash cost per pound of copper produced, net of by-product credits, for the three months ended June 30, 2018 was $1.64, an increase of 32% from the same period in 2017, mainly as a result of higher consumable costs and lower capitalized stripping. Sustaining cash cost per pound of copper produced, net of by-product credits, for the three months ended June 30, 2018 was $1.82, consistent with the same period in 2017, as reduced sustaining capital expenditures offset higher cash costs.

Manitoba Operations Review

During the second quarter of 2018, the Manitoba operations produced 33,170 tonnes of zinc, 10,807 tonnes of copper and 32,363 ounces of gold-equivalent precious metals. Production of copper was comparable to the same period in 2017, while production of gold and silver was 19% and 34% higher, respectively. Zinc production was 5% lower compared to the same period in 2017 as a result of lower zinc grades at Lalor, in line with the mine plan.

A failure of one of two main exhaust fans at Lalor in June has created operating restrictions underground that are delaying the ramp-up to 4,500 tonnes per day and limiting ore production to approximately 3,000 tonnes per day. Repairs to the fan are expected to be completed in August.

Total ore mined at Hudbay’s Manitoba operations during the second quarter of 2018 decreased by 7% compared to the same period in 2017. Increased production at the Reed mine was offset by decreased production at the 777 mine. Overall, gold and silver grades were 11% and 21% higher, respectively, while copper and zinc grades were 5% and 14% lower, respectively, in the second quarter of 2018 compared to the same period of 2017. Grade variances were due to planned stope sequencing. Unit operating costs for all Manitoba mines for the second quarter of 2018 increased by 22% compared to the same period in 2017 for the reasons described below. Lalor unit costs are expected to be elevated in the third quarter of 2018 due to reduced production and costs arising from the exhaust fan failure.

Ore processed in Flin Flon in the second quarter of 2018 was consistent with the same period in 2017. Lower production at the 777 mine was offset by the transfer of excess Lalor ore to the Flin Flon concentrator and higher-than-expected ore output from the Reed mine. Copper and zinc recoveries in the second quarter of 2018 were consistent with the same period in 2017 while gold and silver recoveries were 9% and 12% higher, respectively, due to higher head grades. Unit operating costs at the Flin Flon concentrator were 14% higher in the second quarter of 2018 compared to the same period in 2017 as a result of higher maintenance expenditures. Ore processed was 10% higher and copper recoveries were 4% higher at the Stall concentrator in the second quarter of 2018 compared with the same period in 2017, due to ongoing operational and maintenance improvements and better metallurgical understanding of the Lalor ore. Unit operating costs at the Stall concentrator were 4% lower in the second quarter of 2018 compared to the same period in 2017 as a result of the increased throughput.

Manitoba combined mine, mill and G&A unit operating costs in the second quarter and year-to-date in 2018 were 10% and 13% higher, respectively, than in the same periods in 2017 due mainly to higher 777 and Lalor mining costs, Flin Flon mill maintenance and ore rehandling costs. Lalor costs will continue to be affected by additional costs to truck Lalor ore to the Flin Flon mill. Ore production at Reed was substantially complete at the end of July, as planned.

As a result of a number of factors including cold weather in the first quarter, higher costs at the 777 mine and the impact of a fan outage at the Lalor mine, Hudbay expects Manitoba combined mine/mill unit operating costs to be between C$125 and C$135 per tonne in 2018, with higher costs during the third quarter of 2018 while Lalor exhaust fan repairs are completed. Production of all metals is expected to be within full year guidance.

Cash cost per pound of copper produced, net of by-product credits, in the second quarter of 2018 was negative $0.71 per pound of copper produced. This was lower compared to the same period in 2017, primarily as a result of significantly increased zinc by-product credits, partially offset by the factors affecting unit operating costs described above.

Sustaining cash cost per pound of copper produced, net of by-product credits, in the second quarter of 2018 was $0.38, which is consistent with the prior year as the lower cash cost was offset by higher planned sustaining capital expenditures.

Credit Facility Extension & Amendments

On June 15, 2018 we entered into amendments to our senior credit facilities to extend the maturity date by one year to July 14, 2022 from July 14, 2021 and to incorporate various amendments to the terms and conditions of the facilities to provide Hudbay with greater flexibility. The two facilities have substantially similar terms and conditions and continue to provide revolving credit to a maximum amount of up to $550 million.

Dividend Declared

A semi annual dividend of C$0.01 per share was declared on July 31, 2018. The dividend will be paid on September 28, 2018 to shareholders of record as of September 7, 2018.

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 29 of Hudbay’s management’s discussion and analysis for the three and six months ended June 30, 2018 available on SEDAR at www.sedar.com and EDGAR at www.sec.gov.
