TORONTO, ONTARIO--(Marketwired - Feb 19, 2015) - HudBay Minerals Inc. ("Hudbay" or the "company") (HBM.TO)(HBM) today released its fourth quarter 2014 financial results. In the fourth quarter of 2014, operating cash flow before change in non-cash working capital decreased to negative $3.5 million from $0.8 million in the fourth quarter of 2013. Operating cash flow in the fourth quarter of 2014 was impacted by lower year-over-year revenues from lower copper sales volumes, with approximately 40% of copper produced during the quarter in-transit and unsold, and an 18% decrease in realized copper prices. Cash flow from operations was also negatively affected by the previously disclosed unscheduled two-week shutdown of the 777 shaft, which caused the Manitoba business to miss its 2014 production guidance targets for zinc and precious metals and achieve the lower end of its guidance range for copper production.

"2014 represented a turning point for Hudbay with the completion of construction of three new mines and the delivery of an initial 26% year over year increase in copper production," said David Garofalo, president and chief executive officer. "In 2015, we remain on track to achieve our target of at least a further 270% year over year increase in copper production and to improve our unit operating costs significantly through further economies of scale."

Profit and earnings per share in the fourth quarter of 2014 were $49.6 million and $0.21, respectively, compared to a loss and loss per share of $61.5 million and $0.32 in the fourth quarter of 2013, respectively. The higher profit is mostly the result of a non-cash tax recovery arising from the recognition of previously unrecognized temporary differences in both Peru and Manitoba.

Profit and earnings per share for the fourth quarter of 2014 were affected by, among other things, the following items:

	Pre-tax gain (loss) ($ millions)	After-tax gain (loss) ($ millions)	Per Share ($/share)
Augusta related costs	(4.2)	(3.1)	(0.01)
Loss on mark-to-market of embedded derivative related to long-term debt and warrants	(2.0)	(2.0)	(0.01)
Loss as a result of provisional pricing adjustments	(3.4)	(2.2)	(0.01)
Foreign currency losses	(8.3)	(8.5)	(0.04)
Deferred tax adjustments - Manitoba	-	35.2	0.15
Deferred tax adjustments - Peru	-	38.0	0.16

Hudbay has received commitments from a syndicate of Canadian banks, including its current lenders, to increase the size of the company's corporate revolving credit facility from US$100 million to US$250 million. The credit facility is intended to provide additional liquidity as the Constancia project ramps up to commercial production. The upsized credit facility will be on substantially similar terms to the existing revolving credit facility and will be repayable in 2018. Hudbay expects to complete definitive documentation for the credit facility amendments by the end of the first quarter of 2015.

Hudbay's board of directors has declared a semi-annual dividend in the amount of $0.01 per common share, payable on March 31, 2015 to shareholders of record on March 13, 2015.

Financial and Operating Results

Total revenue for the fourth quarter of 2014 was $128.4 million; $7.7 million lower than the same period in 2013. This decrease was primarily due to lower copper prices and lower copper, gold and silver sales volumes compared to the fourth quarter of 2013, which is a result of the unscheduled two week shutdown of the 777 shaft and approximately 40% of copper produced in the quarter in-transit and unsold.

Fourth quarter 2014 ore production at Hudbay's Manitoba business unit was 13% higher than the prior year's fourth quarter as a result of higher production volumes at Lalor and Reed. Combined mine/mill unit operating costs in the Flin Flon area were 42% higher than the prior year's quarter primarily due to the unscheduled two-week shutdown of the 777 shaft in October. Mine/mill unit costs in the Snow Lake area were 10% lower in the fourth quarter compared to the prior year due to higher throughput from the Lalor mine.

Cash Flows

Operating cash flow before change in non-cash working capital was negative $3.5 million for the fourth quarter of 2014, a $4.3 million decrease compared with the same period in 2013, primarily as a result of lower copper sales volume and lower realized copper prices.

Cash and cash equivalents decreased by $210.4 million from September 30, 2014 to $207.3 million as at December 31, 2014, mainly as a result of $230.7 million of investments, primarily at the Constancia project.

At December 31, 2014, Hudbay had total pro-forma available and committed liquidity of approximately $607 million, including $207.3 million in cash and cash equivalents and availability under the company's credit facilities, including the increased amount committed by the lenders under Hudbay's corporate revolving credit facility. Hudbay expects that this will be sufficient to meet its liquidity needs for 2015.

Constancia

At Hudbay's 100% owned Constancia project in Peru, physical construction was essentially completed and copper concentrate production began as expected during the fourth quarter of 2014. Commercial production remains on track for the second quarter of 2015 and the mine is expected to achieve full capacity in the second half of the year. Safety remains a primary focus at the operation with the project achieving approximately 21 million hours worked and only one lost time injury in 2014.

Commissioning is ongoing and copper concentrate produced to date has met specifications. Trucking to the port commenced in early January and the first sale of concentrate is expected later in the first quarter of 2015.

Initial mining of softer supergene ore from the main Constancia pit is expected to result in the concentrator processing ore at average grades 30% above reserve grade in the first five years of the projected 22 year mine life. There are currently approximately 800,000 tonnes of ore on the run-of-mine pad and an additional 1.8 million tonnes of broken ore in the Constancia pit, representing approximately one month of expected throughput in the plant at design capacity. Mining and civil earthworks productivity has been at or above expectations.

Rosemont

Rosemont is a copper project located in Pima County, Arizona, approximately 50 kilometres southeast of Tucson. Hudbay's ownership in the Rosemont project is subject to an earn-in agreement with United Copper & Moly LLC ("UCM"), pursuant to which UCM has earned a 7.95% interest in the project and may earn up to a 20% interest.

The 43 hole confirmatory drill program was completed on time in December with a total of approximately 93,000 feet drilled. A metallurgical test program has commenced with initial results expected in the second quarter of 2015 and final results expected in the third quarter of 2015. Permitting efforts remain ongoing. On February 3, 2015, the Arizona Department of Environmental Quality issued the Clean Water Act Section 401 Water Quality Certification. The remaining required key permits are the final Record of Decision from the U.S. Forest Service and the Clean Water Act Section 404 Permit from the U.S. Army Corps of Engineers.

Non-IFRS Financial Performance Measures

Operating cash flow per share and cash cost per pound of copper sold are included in this news release because the company believes that, in the case of operating cash flow per share, it helps investors and management to evaluate changes in cash flow while taking into account changes in shares outstanding, and in the case of cash cost per pound of copper sold, it helps investors assess the performance of the company's operations. 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.

Cash cost per pound of copper sold

Cash cost per pound of copper sold is a non-IFRS measure that management uses as a key performance indicator to assess the performance of the company's operations. Hudbay's calculation designates copper as its primary metal of production as it has been, and is expected to be, the largest component of revenues. The calculation is presented in two manners:

• Cash cost per pound of copper sold, before by-product credits - This measure is gross of by-product revenues and is a function of the efforts and costs incurred to mine and process all ore mined. However, the measure divides this aggregate cost over only pounds of copper sold, Hudbay's primary metal of production. This measure is generally less volatile from period to period, as it is not affected by changes in the price received for by-product metals. It is, however, significantly affected by the relative mix of metal sales, and an increase in production of a by-product metal will tend to result in an increase in cash costs under this measure, regardless of the profitability of the increased by-product metal production.
• Cash cost per pound of copper sold, net of by-product credits - In order to calculate the cost to produce and sell copper, the net of by-product credits measure subtracts the revenues realized from the sale of the metals other than copper. The by-product revenues from zinc, gold and silver are significant and are integral to the economics of Hudbay. The economics that support Hudbay's decision to produce and sell copper would be different if the company did not receive revenues from the other significant metals being extracted and processed. This measure provides management and investors with an indication of the minimum copper price consistent with positive operating cash flows and operating margins, assuming by-product metal prices are consistent with those prevailing during the reporting period. It also serves as an important operating statistic that management and investors utilize to measure Hudbay's operating performance versus that of its competitors. However, it is important to understand that if by-product metal prices decline alongside copper prices, the cash cost net of by-product credits would increase, requiring a higher copper price than that reported to maintain positive cash flows and operating margins.

The following table presents Hudbay's calculation of gross cash cost per pound of copper sold and cash cost per pound of copper sold, net of by-product credits for the three months and year ended December 31, 2014 and 2013.

Cash cost after by-product credits in the fourth quarter of 2014 was $1.60/lb, compared to $2.16/lb for the same period in 2013. Cash cost before by-product credits in the fourth quarter of 2014 was $1.64/lb higher compared to the same period in 2013 primarily due to a higher ratio of zinc to copper sales in the current quarter, resulting in higher volume-related zinc costs per pound of copper sold. The increase in by-product credits of $2.20/lb compared to the same period in 2013 was also due primarily to the higher ratio of zinc to copper sales. Consequently, these two offsetting factors resulted in a net decrease to cash cost after by-product credits in the fourth quarter of 2014 compared to the same period in 2013.

Year-to-date cash cost after by-product credits was $1.98/lb, compared to $1.91/lb in 2013. The increase in cash cost before by-product credits of $0.45/lb was primarily due to higher treatment and refining charges and increased purchased zinc concentrate usage in 2014 compared to 2013. By-product credits for the year ended December 31, 2014 were $0.38/lb higher than the same period in 2013 primarily as a result of higher realized zinc prices in 2014 compared to 2013. Consequently, these two offsetting factors resulted in a net increase to the full year cash costs after by-product credits compared to the same period in 2013.
