Hudbay Minerals Inc. - Exhibit 99.3 - Filed by newsfilecorp.com

Toronto, Ontario, February 21, 2018 – Hudbay Minerals Inc. (“Hudbay” or the “company”) (TSX, NYSE:HBM) today released its fourth quarter and full year 2017 financial results. All amounts are in U.S. dollars, unless otherwise noted.

Net profit and basic and diluted earnings per share in the fourth quarter of 2017 were $99.7 million and $0.38, respectively, compared to a net loss and loss per share of $47.3 million and $0.20, respectively, in the fourth quarter of 2016.

In the fourth quarter of 2017, operating cash flow before change in non-cash working capital was $171.9 million, compared to $122.3 million in the fourth quarter of 2016. The increase in operating cash flow is the result of higher realized copper and zinc prices, while higher zinc sales and precious metals sales offset lower copper sales.

“We ended 2017 on a positive note by achieving or exceeding production guidance and continuing to grow positive free cash flow while reducing debt,” said Alan Hair, president and chief executive officer. “Our focus for 2018 is delivering on this year’s operating targets and completing the ramp-up of base metal ore production at Lalor, commencing production from the Lalor gold zones and Pampacancha, and moving Rosemont through the permitting process into development.”

1}Operating cash flow before change in non-cash working capital.
²Cash 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, 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 fourth quarter of 2017 were affected by, among other things, the following items:

	Pre-tax gain	After-tax gain	Per share
	(loss)	(loss)	gain (loss)
	($ millions)	($ millions)	($/share)
Mark-to-market adjustments of various items	(5.6)	(4.3)	(0.02)
Past service pension costs	(10.4)	(6.9)	(0.03)
Gain on contingent consideration from Balmat sale	6.4	6.4	0.03
Asset impairment	(11.3)	(7.5)	(0.03)
Non-cash deferred tax adjustments	-	45.4	0.17

Compared to the fourth quarter of 2016, production of zinc, gold and silver in concentrate increased due to increased Lalor mine throughput and higher zinc grades at 777, while copper production remained consistent.

In the fourth quarter of 2017, consolidated cash cost per pound of copper produced, net of by-product credits, was $0.77, a decrease compared to $0.85 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 fourth quarter of 2017 was $1.49, up from $1.46 in the fourth quarter of 2016. The increase in all-in sustaining cash cost was driven by higher planned sustaining capital expenditures in Manitoba.

Cash and cash equivalents increased by $27.6 million in the fourth quarter of 2017 to $356.5 million at December 31, 2017. This increase was mainly a result of operating cash flow of $129.4 million, partly offset by $88.0 million of capital expenditures and $9.5 million in expenditures related to financing activities.

Net debt declined to $623.1 million at December 31, 2017 from $649.6 million at September 30, 2017, as a result of cash flow from Hudbay’s operations. At December 31, 2017, total liquidity, including cash and available credit facilities, was $777.9 million, up from $749.9 million at September 30, 2017. Over the course of 2017, net debt declined from $1,085.3 million to $623.1 million.

During the fourth quarter, Hudbay recognized a pre-tax expense of $10.4 million for past service pension costs arising from new collective bargaining agreements in the Manitoba business unit. The company also recognized an asset impairment charge of $11.3 million related to equipment purchased to build a new concentrator in Snow Lake, Manitoba, that the company no longer expects to be usable in its operations. Hudbay realized a gain of $6.4 million upon receipt of deferred consideration from the sale of the Balmat mine, which followed the completion of certain milestones.

During the fourth quarter of 2017, the Peru operations produced 33,837 tonnes of copper, which was approximately 9% higher than production in the third quarter of 2017 as a result of improved copper head grade and copper recoveries, and consistent with the same quarter of 2016 as expected grade decline was offset by improved mill throughput. In 2017, copper production at Constancia exceeded the guidance ranges, while precious metals production was slightly below the lower end of the guidance range.

Recoveries of copper, gold and silver were higher in the fourth quarter of 2017, compared to the same period in 2016. Optimization of plant performance continues to be a focus at Constancia.

Combined mine, mill and G&A unit operating costs in the fourth quarter of 2017 were 22% higher than the same period in 2016. The higher combined unit costs are mostly related to decreased capitalized stripping, higher utility prices and higher overall operating costs due to increased molybdenum production during the period. Additionally, increased plant maintenance costs were incurred during a significant scheduled plant shutdown. Full year 2017 unit operating costs were higher than guidance expectations due to lower than expected mill throughput in the first half of the year combined with factors affecting the fourth quarter costs described above.

Cash cost per pound of copper produced, net of by-product credits, for the three months ended December 31, 2017 was $1.38, an increase of 24% from the same period in 2016 mainly as a result of lower deferred stripping, increased plant cash costs and profit sharing.

Sustaining cash cost per pound of copper produced, net of by-product credits, for the three months ended December 31, 2017 was $1.81, an increase of 18% from the same period in 2016 as a result of the factors noted above.

Negotiations to secure surface rights over the Pampacancha deposit are ongoing. The community has provided Hudbay with access to the land to carry out early-works activities and Hudbay expects to begin ore production later this year. In the event that the commencement of mining at Pampacancha is unexpectedly delayed beyond 2018, Hudbay expects to mine material from the Constancia pit instead, which would not impact copper production guidance, but would reduce 2018 Peru precious metals production guidance by approximately 25%.

Twin hole drilling in the Constancia pit has indicated that the positive copper grade bias versus resource grades that has been experienced since the start of Constancia’s production is expected to persist through the life of the deposit, although the extent of the bias is expected to be less than what has been experienced to date. 2018 Peru copper guidance partially reflects the anticipated grade bias; work is ongoing to develop a revised mine plan and updated reserves, which are expected to be released by April 2018.

During the fourth quarter of 2017, the Manitoba operations produced 33,055 tonnes of zinc, 9,338 tonnes of copper and 32,150 ounces of gold-equivalent precious metals. Production of zinc and precious metals was higher than the same quarter in 2016 by approximately 13% and 22%, respectively, as a result of higher grades at all mines as well as higher ore production at Lalor. Production of all metals in Manitoba for full year 2017 was within the guidance ranges.

Ore mined at Hudbay’s Manitoba operations during the fourth quarter of 2017 decreased by 5% compared to the same period in 2016 primarily as a result of lower production at the 777 mine. Ore mined at the 777 mine declined as ground conditions necessitated the implementation of a more conservative stope sequence in order to adapt to more challenging operating conditions as the mine ages. Lower than planned equipment availability and delays in the mine sequence resulting from a plugged paste backfill line in the third quarter also impacted fourth quarter 777 production rates. Overall copper, zinc, gold and silver grades were higher in the fourth quarter of 2017 compared to the same period in 2016 by 9%, 17%, 25% and 26%, respectively, as a result of higher grades at all mines. Unit operating costs in the fourth quarter of 2017 were 44% higher compared to the same period in 2016.

Hudbay ceased capitalizing Reed development costs in the third quarter of 2017 as a result of the mine’s expected closure in the third quarter of 2018, resulting in higher Reed unit operating costs compared to prior periods. The 777 mine’s unit costs were negatively impacted by lower production as a result of the items noted above. Consistent with Hudbay’s revised mine plan, Lalor’s unit costs reflect increased cement rock filling costs as well as substantial operating and capital development work that was undertaken to increase Lalor’s production rate to 4,500 tonnes per day by the third quarter of 2018. The successful ramp up of ore production from the Lalor mine has resulted in the accumulation of an ore stockpile which exceeds the Stall concentrator’s current milling capacity. With the intention to take advantage of higher metal prices and increase Hudbay’s revenues, excess Lalor ore was trucked to the Flin Flon mill for processing, which contributed to the increased unit costs for Lalor.

Ore processed in Flin Flon in the fourth quarter of 2017 was 13% lower than the same period in 2016 primarily as a result of lower mine production, and challenges in primary crushing due to frozen blocks of ore feed recovered from stockpiles. Copper and precious metals recoveries were higher in the fourth quarter of 2017 compared to the same period in 2016 as a result of higher head grades, and improvements made to the mill. Unit operating costs at the Flin Flon concentrator were 12% higher in the fourth quarter of 2017 compared to the same period in 2016 as a result of higher maintenance expenditures and reduced production. Ore processed at the Stall concentrator in the fourth quarter of 2017 was 4% higher than the same period in 2016. Unit operating costs at the Stall concentrator were 5% higher in the fourth quarter of 2017 compared to the same period in 2016 as a result of higher maintenance expenditures resulting from unplanned repairs.

Manitoba combined mine, mill and G&A unit operating costs in the fourth quarter and full year in 2017 were 29% and 27% higher, respectively, than in the same periods in 2016 due to the factors described above. In addition, the stockpiling of Lalor ore 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. Processing the additional Lalor production in Flin Flon is expected to drive economies of scale and additional revenues through a faster ramp up. Combined mine/mill unit operating costs in Manitoba exceeded the guidance range for the reasons noted above. Zinc plant production and unit operating costs were within the guidance ranges for 2017.

Cash cost per pound of copper produced, net of by-product credits, in the fourth quarter of 2017 and full year were negative $1.42 and negative $0.59 per pound of copper produced, respectively. These were lower compared to the same periods in 2016 due primarily to significantly increased by-product credits for all metals, which were partially offset by expected higher costs at Hudbay’s 777 and Reed mines during this part of their mine lives.

Sustaining cash cost per pound of copper produced, net of by-product credits, in the fourth quarter of 2017 and full year were negative $0.35 and $0.23 per pound of copper produced, respectively, compared to $0.58 and $1.16 in the prior year as a result of the same factors described above, which were partially offset by planned increased capital spending.

Work continues with the U.S. Forest Service on the draft Mine Plan of Operations, which is progressing as planned. The remaining key federal permit outstanding is the Section 404 Water Permit from the U.S. Army Corps of Engineers.

On November 27, 2017, opponents of the Rosemont project filed a lawsuit against the U.S. Forest Service challenging, among other things, the issuance of the Final Record of Decision in respect of Rosemont. This is one of two active lawsuits challenging the Final Record of Decision and is one of the many legal challenges that have been advanced against the Rosemont permitting process. Hudbay is confident that Rosemont’s permits will continue to be upheld.

Three-year collective bargaining agreements have been entered into with Hudbay’s unionized workforces at each of its Manitoba and Peru operations, providing labour stability.

Hudbay declared a semi-annual dividend of C$0.01 per share on February 21, 2018. The dividend will be paid on March 29, 2018 to shareholders of record as of March 9, 2018.

Production, capital expenditure, exploration and unit cost guidance for 2018 remains unchanged from that provided on January 17, 2018.
