Hudbay Releases First Quarter 2013 Results Summary

Wed, 01 May 2013 17:34:00 -0400

TORONTO, ONTARIO--(Marketwired - May 1, 2013) - HudBay Minerals Inc. ("Hudbay" or the "company") (TSX:HBM)(NYSE:HBM) today released its first quarter 2013 financial results. In the first quarter of 2013, Hudbay recorded a profit and earnings per share of $1.9 million and $0.01, respectively, compared to a profit and earnings per share of $3.4 million and $0.03, respectively, in the first quarter of 2012.

The first quarter of 2013 profit was affected by, among other things, the following items:

Financial and Operating Results

Total revenue for the first quarter of 2013 was $119.9 million, $67.1 million lower than the same period in 2012. This decrease was primarily due to lower sales volumes mainly as a result of the closures of Trout Lake and Chisel North mines and lower metals prices compared to the first quarter of 2012.

First quarter 2013 ore production at Hudbay's Manitoba business unit was 16% lower than the prior year's first quarter due to the planned permanent closures of the Trout Lake and Chisel North mines in June 2012 and September 2012, respectively, partially offset by production at Lalor. Overall mine operating costs per tonne were 6% lower than the prior year's quarter with the closure of the higher-cost Trout Lake and Chisel North mines, partially offset by higher operating costs per tonne of ore at the 777 mine.

Operating costs per tonne of ore at 777 in the first quarter of 2013 were 21% higher, compared to the same period in 2012, primarily due to increased contractor costs and additional ground support requirements. Additional contractor work was required at 777 in the past two quarters due to issues with equipment availability in the fall of 2012 that reduced operating development rates. Equipment availability has returned to normal levels, operating development progress is sufficient to support normal mining rates, and contractors are no longer assigned to operating development work. Full year unit operating costs at 777 are expected to be in line with guidance.

The operating cost per tonne of ore processed in the first quarter of 2013 at the Flin Flon concentrator increased as expected by 22% compared to the same period in 2012, largely due to reduced ore throughput following closure of the Trout Lake mine. Operating costs at the Snow Lake concentrator for the first quarter of 2013 increased 27% from the same period in 2012 due to transitional work to process Lalor ore and additional manpower and training costs to prepare for increased concentrator throughput for the remainder of 2013. Hudbay expects its full year metal in concentrate production and unit costs will be within the guidance range.

Cash Flows

Operating cash flows before change in non-cash working capital were $12.3 million, reflecting a decrease of $30.0 million compared to 2012, mainly as a result of lower sales volumes, lower realized prices and reduced gold and silver cash receipts, within the quarter, as a result of the precious metals stream transaction in 2012.

Cash and cash equivalents decreased by $286.6 million from December 31, 2012 to $1,050.5 million as at March 31, 2013. This decrease was mainly driven by $201.3 million in capital expenditures primarily at the Lalor and Constancia projects, and interest and dividend payments of $26.7 million and $17.2 million, respectively.

As at March 31, 2013, Hudbay has total available liquidity of $1,536.0 million, comprised of $1,050.5 million in cash and cash equivalents, US$250.0 million in deposits to be received from Silver Wheaton and availability under its credit facility of $235.5 million net of outstanding letters of credit. These amounts do not include anticipated cash flow from operations. The company is also considering additional financing opportunities, including equipment financing for the Constancia mobile fleet.

Lalor

The company has invested approximately $338 million of its $794 million capital construction budget for the Lalor project to March 31, 2013 and has entered into an additional $84 million in commitments for the project.

During the first quarter of 2013, Hudbay hoisted 81,800 tonnes of ore from the ventilation shaft at Lalor at a copper grade of 0.57% and zinc grade of 9.94%. During the same period, underground project development continued to advance. The company's primary focus is to complete the 910 metre shaft station in the second quarter of 2013 and to continue to ramp to the 955 metre level, which the company expects to reach by the end of the third quarter of 2013. Hudbay is developing ore and waste handling systems as well as the dewatering areas on the 910 and 955 metre levels.

Given the nature of the Lalor project, Hudbay expects to refer to three phases of the Lalor project when determining commercial production for accounting purposes. The first phase of the project includes the main ventilation shaft and associated surface and underground workings that will contribute to the production of ore between 2012 and 2014. Hudbay commenced this phase of commercial production on April 1, 2013 with Lalor initial production contributing to profit starting at that time.

As of April 26, 2013 the main production shaft was sunk to approximately 710 metres and is approximately 72% complete. Hudbay expects shaft sinking to be completed in late 2013. Upon completion of sinking, the installation of the steel sets and guides as well as the headframe changeover will begin. Ore production is expected to transition from the ventilation shaft to the main production shaft by the fourth quarter of 2014, subject to receipt of required regulatory permits.

Hudbay is in the process of completing the final engineering work for the load-out facilities located at the 955 metre level, as well as the main pumping installations. The company is preparing for construction of the main intake fan systems and the main substation, which is scheduled to be completed in the fourth quarter of 2013.

Hudbay expects to submit the Environment Act Licence application for the new concentrator to the Manitoba government in the second quarter of 2013. The new design will incorporate a larger grinding circuit being fed from the surface stockpile. Hudbay will hoist uncrushed ore up the main production shaft at Lalor to be crushed on surface and then conveyed to the surface stockpile. The stockpile will feed a SAG mill and ball mill combination that has design capacity of 5,400 tonnes per day.

Reed Copper Project

During the first quarter, Hudbay's focus for its 70% owned Reed copper project near Flin Flon, Manitoba was advancing the underground ramp and sinking the escape and ventilation raises from surface. Of Hudbay's $72 million capital construction budget, the company has invested approximately $37 million on the project to March 31, 2013 and has entered into an additional $13 million in commitments. Capital expenditures at Reed are expected to total approximately $44 million in 2013.

After completing the first portal development round in October 2012, the underground ramp had advanced approximately 363 metres as of March 31, 2013. In March 2013, Hudbay was able to start hauling waste from underground via haul trucks, which is expected to reduce cycle times and improve the rate of ramp development.

Hudbay expects initial production at the Reed copper project by the fourth quarter of 2013 and full production of approximately 1,300 tonnes of ore per day by the first quarter of 2014.

Constancia

Hudbay has incurred approximately US$480 million in costs of its US$1.5 billion capital construction budget on the Constancia project to March 31, 2013 and has entered into an additional US$534 million in commitments for the project.

The company has secured the mine fleet with 18 haul trucks scheduled for delivery between June 2013 and August 2014.

Tire procurement is underway with a number of tires purchased and contracts arranged to meet fleet requirements. Hudbay expects the arrival of the three hydraulic shovels in August 2013, September 2013 and January 2014, respectively, and to begin pre-stripping activities late in 2013.

Development of the project is approximately 25% complete. Civil earth works for the process plant area are approximately 70% complete and remain on schedule. The principal foundations for the ball and SAG mills are poured and complete. Forms are being erected for the reclaim tunnels and crusher foundation. Progress on the tailings management facility has been negatively impacted by the unusually high rainfall in the first quarter. However, the dry season commenced in April and Hudbay believes the impact on project schedule is recoverable. Targets for initial production in late 2014 and full production in the second quarter of 2015 remain unchanged.

Land access for the power transmission line is being arranged and the negotiation of the power purchase agreement is well advanced. The principal port operator has provided assurances that the concentrate shipments will be accommodated, and Hudbay is considering short term and long term solutions to best serve the project's needs.

In accordance with the agreements Hudbay has entered into with local communities, relocation of affected families is underway and the construction of new housing is in progress. Hudbay has delivered new homes to 14 families, and the remaining 22 families are scheduled to be relocated in 2013.

Permitting and regulatory efforts remain on schedule. The next major permit is the operating permit, which Hudbay expects to receive in the normal course upon commissioning of the mine which is scheduled for early 2015. The company has already received the beneficiation concession, mining permit and approval for the early refund of value added tax on purchases with retroactive effect to December 2012.

Non-IFRS Financial Performance Measures

Operating cash flow per share and cash costs per pound of copper sold ("cash cost") are included in this news release because the company believes that, in the case of operating cash flow per share, it helps investors to evaluate changes in cash flow while taking into account changes in shares outstanding, and in the case of cash costs, they help 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.

Operating cash flow per share

The following table presents Hudbay's calculation of operating cash flow per share for the three months ended March 31, 2013:


	Three Months Ended


	Mar. 31	Mar. 31
($000s except share and per share amounts)	2013	2012

Operating cash flow before change in non-cash working capital	12,261	42,247

Weighted average shares outstanding	172,012,192	171,912,598

Operating cash flow per share	0.07	0.25

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 takes a by-product costing approach, under which the company designates copper as its primary metal of production and from which the company subtracts the net revenues realized from the sale of other metals mined with copper. As there is significant variation in calculation methodologies in practice, Hudbay's cash cost may not be directly comparable with the cash cost of other companies.

Cost to copper concentrate includes all direct mining, milling, and concentrating costs incurred in the production of copper concentrate at Hudbay's mines and mills in addition to general and administrative expenses directly related to those operations. Downstream costs include freight, distribution, and treatment charges related to copper concentrate plus copper refining costs. Net by-product credits include revenue from the sale of zinc, gold, silver, and other by-products less the production costs of zinc and refining costs associated with gold and silver. Realization of deferred revenue under the precious metals stream agreement with Silver Wheaton is not included in net by-product credits.

Copper sales (000s lbs)	17,242		24,072
Cash cost per pound of copper sold ($/lb)	1.78		1.18
¹Indirect costs in cost of sales - mine operating costs

Cash cost for the first quarter of 2013 was $1.78/lb, compared to $1.18/lb for the same period in 2012. The increase is due primarily to the commencement of deliveries of gold and silver to Silver Wheaton under the stream agreement as the non-cash portion of these sales is excluded from by-product credits and the total sales price is relatively lower than the first quarter of 2012. The impact of the stream agreement reduced net by-product credits by approximately $0.79/lb during the quarter.

Note to United States Investors

Information concerning Hudbay's mineral properties has been prepared in accordance with the requirements of Canadian securities laws, which differ in material respects from the requirements of the Securities and Exchange Commission ("SEC") Industry Guide 7.

Under SEC Industry Guide 7, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time of the reserve determination, and the SEC does not recognize the reporting of mineral deposits which do not meet the United States Industry Guide 7 definition of "Reserve".

In accordance with NI 43-101 of the Canadian Securities Administrators, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") Definition Standards for Mineral Resources and Mineral Reserves adopted by the CIM Council on December 11, 2005.

While the terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are recognized and required by NI 43-101, the SEC does not recognize them. You are cautioned that, except for that portion of mineral resources classified as mineral reserves, mineral resources do not have demonstrated economic value. Inferred mineral resources have a high degree of uncertainty as to their existence and as to whether they can be economically or legally mined.

It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Therefore, you are cautioned not to assume that all or any part of an inferred mineral resource exists, that it can be economically or legally mined, or that it will ever be upgraded to a higher category. Likewise, you are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be upgraded into mineral reserves. You are urged to consider closely the disclosure on the technical terms in Schedule A "Glossary of Mining Terms" of Hudbay's annual information form for the fiscal year ended December 31, 2012, available on SEDAR at www.sedar.com and incorporated by reference as Exhibit 99.1 in Hudbay's Form 40-F dated March 28, 2013 (File No. 001-34244).

Hudbay Announces Increases in Metals Reserves and Resources and Declares First Phase of Commercial Production at Lalor

Wed, 27 Mar 2013 15:00:00 -0400

TORONTO, ONTARIO--(Marketwire - March 27, 2013) - HudBay Minerals Inc. ("Hudbay" or the "company") (TSX:HBM)(NYSE:HBM) today announced an increase to its copper equivalent proven and probable mineral reserves for the third consecutive year. Copper equivalent proven and probable mineral reserves increased by 12% to approximately 3.6 million tonnes, including approximately 4 million ounces of precious metal equivalent proven and probable reserves, which increased by 16% from 2012. In addition, Hudbay has approximately 1.9 million tonnes of copper equivalent measured and indicated resources and approximately 2.2 million tonnes of copper equivalent inferred resources, including approximately 2 million ounces of precious metal equivalent measured and indicated resources and approximately 3 million ounces of precious metal equivalent inferred resources.

Exploration success and resource evaluation accounted for approximately 88% of the increase in copper equivalent reserves and resources and the entire increase in precious metal equivalent reserves and resources, with the balance due to revised commodity price and exchange rate assumptions.

¹All mineral resources referred to in this news release are exclusive of and additional to stated mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Overall copper equivalent reserves and resources and precious metal equivalent reserves and resources are in-situ contained metal based on estimated reserves and resources at Hudbay's Constancia, Pampacancha, 777, Lalor, Reed, Back Forty, Tom and Jason and Lost properties. Copper equivalent metal for 2013 calculated using a copper price of US$2.75 per pound, zinc price of US$0.95 per pound, gold price of US$1,250.00 per ounce, silver price of US$25.00 per ounce, lead price of US$0.90 per pound and molybdenum price of US$14.00 per pound. Copper equivalent metal for 2012 was calculated using a copper price of US$2.75 per pound, zinc price of US$0.95 per pound, gold price of US$1,100.00 per ounce, silver price of US$22.00 per ounce, lead price of US$0.85 per pound and molybdenum price of US$13.00 per pound.

²For 2013 and 2012, precious metal equivalent reserves and resources include gold and silver only, expressed in ounces of gold with silver converted to gold at a ratio of 50:1.

On a per share basis, Hudbay's copper equivalent proven and probable reserves grew to 46.1 pounds per share compared to 41.3 pounds per share in 2012. Copper equivalent measured and indicated resources grew to 24.1 pounds per share compared to 11.9 pounds per share in 2012 and copper equivalent inferred resources grew to 28.3 pounds per share compared to 21.6 pounds per share in 2012.

Hudbay also announced that, based on production results to date in 2013 from the Lalor mine, the company expects to achieve commercial production from the first phase of Lalor as at March 31, 2013, with Lalor initial production expected to contribute to profit starting in April 2013.

"We have grown our metals reserves and resources per share for the third consecutive year and, in doing so, we have been able to provide our shareholders with increasing leverage to commodity exposure on a per share basis," said David Garofalo, President and Chief Executive Officer. "Much of this success was attributed to growth from Constancia and the higher grade Pampacancha deposit in Peru. As we continue our Peru exploration program and begin to explore from underground at our Lalor project, we are hopeful we will continue increasing reserves and resources going forward."

Additional Information

The reserve and resource estimates included in this news release were prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute on Mining, Metallurgy and Petroleum Standards on Mineral Resources and Reserves: Definitions and Guidelines. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Manitoba

To estimate mineral reserves, measured and indicated mineral resources were first estimated in a 12-step process, which includes determination of the integrity and validation of the data collected, including confirmation of specific gravity, assay results and methods of data recording. The process also includes determining the appropriate geological model, selection of data and the application of statistical models including probability plots and restrictive kriging to establish continuity and model validation. The resultant estimates of measured and indicated mineral resources are then converted to proven and probable mineral reserves by the application of mining dilution and recovery, as well as the determination of economic viability using full cost analysis. Other factors such as depletion from production are applied as appropriate.
Estimated inferred mineral resources within our mines were estimated by a similar 12-step process, used to estimate measured and indicated resources.
The zinc price used for mineral reserve and resource estimations for the Manitoba mines was US$1.01 per pound (includes premium), the copper price was US$2.75 per pound, the gold price was US$1,250.00 per ounce and the silver price was US$25.00 per ounce using an exchange of 1.05 C$/US$.
For additional details relating to the estimates of mineral reserves and resources at the 777 mine, including data verification and quality assurance/quality control processes refer to the "Technical Report 777 Mine, Flin Flon, Manitoba, Canada" dated October 15, 2012 on SEDAR.
For additional details relating to the estimates of mineral reserves and resources at the Lalor project, including data verification and quality assurance/quality control processes refer to the "Pre-Feasibility Study Technical Report, on the Lalor Deposit" dated March 29, 2012 on SEDAR.

Peru

For additional details relating to the estimates of mineral reserves and resources at the Constancia project, including data verification and quality assurance/quality control processes refer to "The Constancia Project, National Instrument 43-101 Technical Report" as filed on SEDAR by Hudbay on November 6, 2012.
Copper Equivalent % is calculated for the in situ value of contained metals using the following $US metal price assumptions, Cu=2.75/lb Mo=13.00/lb, Ag=22.00/oz and Au=1,100.00/oz.
The Constancia and Pampacancha mineral reserves are based on a Peruvian Sole: US Dollar exchange rate of 2.85:1 and the following long term metals prices: Cu US$2.75/lb; Ag US$23.00/oz; Au US$1,150.00/oz; and Mo US$14.00/lb.
The Constancia mineral resources are reported at a 0.12% copper cut-off and are based on the following assumptions: a copper price of US$2.88/lb, a molybdenum price of US$14.00/lb, copper recovery of 89%, molybdenum recovery of 60%, processing cost of US$5.50/t and mining cost of US$1.30/t.
The Pampacancha mineral resources are reported at a 0.20% copper cut-off and are based on a Peruvian Sole: US Dollar exchange rate of 2.85:1 and the following long term metals prices: Cu US$2.75/lb; Ag US$23.00/oz; Au US$1,150.00/oz; and Mo US$14.00/lb.
Measured and indicated mineral resources were estimated in house. The process includes determination of the integrity and validation of the data collected, including confirmation of specific gravity, assay results and methods of data recording. The process also includes determining the appropriate geological model, selection of data and the application of statistical models including probability plots to establish continuity and model validation.

Reed

The weighted average (based on planned production tonnage) used in the Reed pre-feasibility study for mineral reserve estimation for copper was US$2.95 per pound, the gold price was US$1,269.09 per ounce and the silver price was US$24.78 per ounce using an exchange rate of 1.034 C$/US$.

Other Properties

Back Forty mineral resources were estimated using NSR cut-off values based on metal price assumptions of US$0.96 per pound zinc, US$3.65 per pound copper, US$1.01 per pound lead, US$1,456.36 per troy ounce gold and US$27.78 per troy ounce silver and applying recoveries for each metallurgical domains determined for the deposit. Back Forty mineralization offering reasonable prospects for economic extraction by open pit were determined using the Lerchs-Grossman optimizing algorithm. Optimization parameters were based on costs derived in the "Technical Report, Preliminary Economic Assessment on the Back Forty Deposit, Menominee County, Michigan, USA" dated April 26, 2012 as well as updated metallurgical recoveries and updated metal prices. Average NSR cut-off values for the open pit mineral resources were US$27.75/tonne and average NSR cut-off values for an underground mining scenario were US$66.45/tonne.
Tom and Jason Metal prices used (US$0.57/lb Zn, US$0.35/lb Pb and US$7.00/oz Ag) and a gross dollar value cut-off of US$50/tonne. Ag values were capped at 550 g/t. For additional detail relating to the Tom/Jason mineral resource estimates see "Technical Report on the Tom and Jason Deposits, Yukon territory, Canada" as filed on SEDAR by Hudbay on May 24, 2007.

Hudbay Releases Fourth Quarter 2012 Results

Wed, 20 Feb 2013 17:12:00 -0500

TORONTO, ONTARIO--(Marketwire - Feb. 20, 2013) -

Summary

Production of all metals in concentrate and overall unit operating costs met full year 2012 guidance.
Fourth quarter operating cash flow before stream deposit and change in non-cash working capital decreased to $6.0 million, mainly due to lower realized metals prices, the impact of the precious metal stream transaction on cash proceeds received for gold and silver sold in the quarter and unusually high sales volumes in the comparable 2011 period.
Profit and earnings per share in the fourth quarter of 2012 of $7.4 million and $0.04, respectively.
Development of three new mines proceeding well with first full quarter of ore production from the ventilation shaft at Lalor, full scale civil works underway at Constancia and ramp development advancing well at Reed.
Lalor project estimated capital expenditures increased by $90 million to $794 million as scope changes, including a 20% increase in grinding capacity to 5,400 tonnes per day, as well as improved estimation from completion of basic engineering are incorporated.
Drilling at Constancia's higher grade Pampacancha satellite deposit continued to expand the known deposit, raising the possibility of further grade enhancements early in the mine life.
Semi-annual dividend of $0.10 per share declared.

HudBay Minerals Inc. ("Hudbay" or the "company") (TSX:HBM)(NYSE:HBM) today released its fourth quarter 2012 financial results. In the fourth quarter of 2012, Hudbay recorded a profit and earnings per share of $7.4 million and $0.04, respectively, compared to a profit and earnings per share of $34.3 million and $0.21, respectively, in the fourth quarter of 2011.

The fourth quarter of 2012 profit was affected by, among other things, the following items:

	Pre-tax gain (loss) ($ millions)		After-tax gain (loss) ($ millions)		Per Share ($/share)
Impairments and mark-to-market adjustment related to junior mining investments	(4.1	)	(4.1	)	(0.02	)
Gain on mark-to-market of embedded derivative related to long term debt	1.9		1.9		0.01
Impact on deferred tax expense of translation of Peruvian tax basis	-		2.7		0.02
Impact on deferred taxes of change in discount rates on decommissioning and restoration liabilities	-		1.1		0.01
Foreign exchange gain	9.1		8.5		0.05
Loss as a result of provisional pricing adjustments	(3.5	)	(2.2	)	(0.01	)
Loss on forward zinc purchase contracts related to fixed price customer sales	(0.6	)	(0.4	)	-

"For the sixth consecutive year, Hudbay met its production guidance, which is a testament to our operating team and our reliable northern Manitoba assets," said David Garofalo, Hudbay's president and chief executive officer. "Our focus in 2013 is to continue to advance our robust portfolio of development assets, which we expect to provide significant copper, gold and zinc production growth over the next two years as they are brought into production."

Hudbay's board of directors has declared a semi-annual dividend in the amount of $0.10 per common share, payable on March 28, 2013 to shareholders of record on March 18, 2013.

Financial and Operating Results

Total revenue for the fourth quarter of 2012 was $181.0 million; $73.3 million lower than the same period in 2011. This decrease was primarily due to lower sales volumes compared to the fourth quarter of 2011, when the company drew down on unusually high copper concentrate inventory. Lower gold prices in the fourth quarter of 2012 reflect in part, the effect of the precious metals stream agreement. For the full year 2012, revenue was $702.6 million, $188.2 million lower than in 2011, mainly as a result of lower sales volumes, primarily due to the reason described above, and lower metals prices.

Fourth quarter 2012 ore production at Hudbay's Manitoba business was 20% lower than the prior year's fourth quarter due to the planned permanent closures of the Trout Lake and Chisel North mines in June 2012 and September 2012, respectively, offset partly by the start of production at Lalor. Overall mine operating costs per tonne were 13% lower than the prior year's quarter with the closure of the higher-cost Trout Lake and Chisel North mines. In addition, the operating cost per tonne of ore processed at the Flin Flon and Snow Lake concentrators increased in the fourth quarter of 2012 as a result of reduced feed to the Flin Flon concentrator and costs associated with the new Snow Lake copper circuit and preparations for the ramp up of Lalor mine production. Production of all metals in concentrate and overall unit operating costs met full year guidance.

Cash Flows

Operating cash flow before stream deposit and change in non-cash working capital was $6.0 million for the fourth quarter of 2012, a $76.2 million decrease compared with the same period in 2011 mainly as a result of lower sales volumes and reduced gold and silver receipts as a result of the stream transaction.

For the full year 2012, operating cash flows before stream deposit and change in non-cash working capital were $143.0 million, reflecting a decrease of $109.2 million compared to 2011, mainly as a result of the lower sales volumes and reduced gold and silver receipts as a result of the stream transaction.

Cash and cash equivalents decreased by $161.9 million during the quarter to $1,337.1 million as at December 31, 2012, mainly as a result of capital expenditures of $180.7 million, primarily on Hudbay's growth initiatives.

Lalor

The company has invested approximately $326 million of the revised $794 million capital construction budget for its wholly owned Lalor project near Snow Lake, Manitoba, to January 31, 2013 and has entered into an additional $93 million in commitments for the project.

The mine portion of the project remains on time and on budget. Basic engineering of the new Lalor concentrator is complete.

Capital expenditures are expected to be approximately $90 million higher than the original budget of $263 million for the concentrator portion of the now $794 million project. Scope changes and improved estimation from completion of basic engineering account for the increase. The scope changes include an increase in the grinding capacity by 20% to 5,400 tonnes per day to better match the potential production shaft capacity. The mine plan, as previously disclosed, contemplates an ore production rate of 4,500 tonnes per day at full production, however, the main production shaft is designed for 6,000 tonnes per day. The new concentrator design also incorporates a longer construction schedule with concentrator startup in late 2015. However, first ore production from the main production shaft is still projected to be on schedule in late 2014, at which time it will be processed at the Snow Lake and Flin Flon mills and a portion stockpiled for the new concentrator upon its commissioning.

During the fourth quarter of 2012, Hudbay hoisted 58,000 tonnes of ore from the ventilation shaft at Lalor. Between August and December 2012, Hudbay hoisted 72,300 tonnes of ore and 79,830 tonnes of waste using the ventilation shaft. Underground project development has continued to advance and Hudbay's primary focus is to reach the 910 metre shaft station and continue to ramp to the 955 metre level. The main production shaft is now sunk to approximately 525 metres and is 53% complete. Hudbay expects shaft sinking to be completed in late 2013. Upon completion of sinking, the installation of the steel sets and guides as well as the headframe changeover will begin.

Hudbay is in the process of completing the final engineering work for the load-out facilities located at the 955 metre level, as well as completing the main pumping installations. The company is preparing for construction of the main intake fan systems and the main substation during 2013.

Hudbay expects to submit the Environmental Act Licence application for the new concentrator to the provincial government in the first half of 2013. The new design will incorporate a larger grinding circuit being fed from the surface stockpile. Hudbay will hoist uncrushed ore up the Lalor shaft to be crushed on surface and then conveyed to the surface stockpile. The stockpile will feed a SAG mill and ball mill combination that has design capacity of 5,400 tonnes per day.

Reed Copper Project Development Progressing on Schedule

During the fourth quarter, Hudbay's focus for its 70% owned Reed copper project near Flin Flon, Manitoba was underground ramp development and completion of surface infrastructure.

Of the company's $72 million capital construction budget, the company has invested approximately $26 million on the project to January 31, 2013 and has entered into an additional $20.5 million in commitments for the project. Capital expenditures at Reed are expected to total approximately $44 million in 2013.

After completing the first portal development round in October 2012, the underground ramp had advanced approximately 174 metres as of January 31, 2013. In December 2012, Hudbay submitted to the provincial government the Environmental Act Licence application for Reed which, upon receipt, will allow for the commencement of full production.

Hudbay expects initial production at the Reed copper project by the fourth quarter of 2013 and full production of approximately 1,300 tonnes of ore per day by the first quarter of 2014.

Construction Progress at Constancia

On August 8, 2012, Hudbay's Board of Directors approved a US$1.5 billion investment in the company's 100% owned Constancia copper project in Peru. The Constancia development schedule contemplates nine quarters of construction, with initial production in late 2014 and full production commencing in the second quarter of 2015.

Hudbay has invested approximately US$351 million of its US$1.5 billion capital construction budget on the project to January 31, 2013 and has entered into an additional US$631 million in commitments for the project. The company expects to incur capital expenditures of approximately $961 million on Constancia for 2013. The project site has sustained a higher than normal amount of rainfall, which has slowed project progress to date. Hudbay believes that the impact on project schedule is recoverable and the targets for initial production and full production remain unchanged. The project's forecasted final costs remain on budget.

Site activity to date includes the completion of 3,500 beds in the construction camp. The tailings management facility, haul roads and water diversion infrastructure are under construction. Hudbay expects to complete the access roads for heavy haulage in the second quarter of 2013, and the waste rock facilities in the third quarter of 2013.

The Pampacancha feasibility study is underway and Hudbay will incorporate further characterization of geotechnical and hydrogeological information in the study.

Structural steel delivery is scheduled to commence in May 2013 and the major steel erection for the plant site is expected to commence in June 2013. Hudbay has secured major long lead items including flotation cells, pumps, regrind mills, SAG mills and crushers and expects to begin receiving these items in March 2013. The primary crusher mechanical installation is anticipated in the fourth quarter of 2013. The company has also secured the mine fleet with 18 haul trucks scheduled for delivery from March 2013 through August 2014. Tire procurement is underway with a number of tires purchased and contracts arranged to meet fleet requirements. Hudbay expects the arrival of the three hydraulic shovels in June, July and December 2013, respectively and to begin pre-stripping activities late in 2013.

In addition, Hudbay has executed a contract for the construction of the 70 kilometre power transmission line from the Tintaya substation. The company is finalizing negotiations on the power purchase agreements with long term pricing expected to be consistent with its original expectations. The principal port operator has provided further assurances that the concentrate shipments will be accommodated and Hudbay is considering the short term and long term solutions to best serve the project's needs.

In accordance with the agreements Hudbay has entered into with local communities, relocation of affected families is underway and the construction of new housing is in progress. Hudbay has delivered new homes to 13 families, and the remaining 23 families are scheduled to be relocated in 2013.

Permitting and regulatory efforts remain on schedule with the approval and receipt of the mining permit in December 2012. This approval followed in the normal course the beneficiation concession that was awarded in June 2012.

The next major permit is the operating permit which Hudbay expects to receive in the normal course upon commissioning of the mine which is scheduled for early 2015. The company has also received approval for the early refund of value-added tax on purchases with retroactive effect to December 2012.

Constancia Exploration Update

In Peru, exploration is ongoing at the Constancia project with three diamond drills. One drill is focused on Pampacancha infill drilling, while the two others are concentrated on Pampacancha West.

Hudbay's objective for the first quarter of 2013 is to drill Pampacancha West, which includes a group of geophysical anomalies located approximately 500 metres west of the main Pampacancha deposit. New drilling has yielded positive results including drill hole PO-12-142, which intersected 14.8 metres at 0.85% copper equivalent grade (at a depth from 11.2 metres to 26 metres) and almost 28 metres at 0.51% copper equivalent grade (at a depth from 91.4 metres to 119.75 metres).

These intersections indicate that magnetite skarn mineralization exists in this western area and exploration of this area will continue to be a priority to understand if a meaningful resource can be delineated.

In addition, Hudbay anticipates recent drilling will have a positive impact on the grade and tonnage at the main Pampacancha deposit for consideration in the new Pampacancha feasibility study. This resource will provide the company with an opportunity to continue to optimize the mine plan with potential to extend higher grades in the mine plan beyond the first five years of production. Among recent drilling results, infill drill hole PO-12-134 in the southern portion of the resource extended mineralization at depth of 108.10 metres at a 2.62% copper equivalent grade (at a depth from 88 metres to 196.1 metres). Drill hole PO-12-129 intersected almost 65 metres at a 1.17% copper equivalent grade (at a depth from 23 metres to 88 metres) at the western margin of the Pampacancha resource, which remains open to the west. A total of 16,593 metres were drilled during 2012 and Hudbay plans on drilling 3,000 metres in the first quarter of 2013 targeting extensions to the northwest and west of the Pampacancha resource and the Pampacancha West mineralization.

Chilloroya South drilling in 2012 yielded interesting results with the presence of some gold mineralization. Geological modeling for future exploration considerations is ongoing. The geophysical anomaly immediately west of the Constancia pit was not fully tested. Two drill holes failed to pierce a significant fault structure to properly test the geophysical anomaly. Near the fault some porphyry mineralization was encountered and further review is required. The opportunity remains to pierce through the faulted structure utilising a larger and more powerful drill.

Non-IFRS Financial Performance Measures

Operating cash flow per share and cash costs 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 to evaluate changes in cash flow while taking into account changes in shares outstanding, and in the case of by-product cash costs, they help investors assess the company's overall costs of metal production and compare those costs to those of other base metal producers.

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.

Operating cash flow per share

Operating cash flow per share	0.03	0.48	0.83	1.50

Cash cost per pound of copper sold

Cash cost per pound of copper sold ("cash cost") is a non-IFRS measure (see "Non IFRS Financial Performance Measures" above) that management uses as a key performance indicator to assess the performance of the company's operations. Hudbay's calculation takes a by-product costing approach, under which the company designates copper as its primary metal of production and from which the company subtracts the net revenues realized from the sale of other metals mined with copper. As there is significant variation in calculation methodologies in practice, Hudbay's cash cost may not be directly comparable with the cash cost of other companies.

Realization of deferred revenue under the precious metals stream agreement with Silver Wheaton is not included in net by-product credits.

¹Indirect costs in cost of sales - mine operating costs

Cash cost for the fourth quarter of 2012 was $2.05/lb, compared to $0.54/lb for the same period in 2011. The increase is due primarily to the commencement of deliveries of gold and silver to Silver Wheaton under the stream agreement as the non-cash portion of these sales is excluded from by-product credits and the total sales price is relatively lower than the fourth quarter of 2011. The impact of the stream agreement reduced net by-product credits by approximately $1.82/lb during the quarter.

Cost to copper concentrate increased and costs of zinc metal sales decreased (resulting in a corresponding increase in net by-product credits) as a result of an update to Hudbay's inventory costing process effective October 1, 2012. This change was necessitated by the accounting requirements related to both stream sales of 777 mine gold and silver, and pre-production revenue at the company's new Lalor and future Reed mines.

Prior to the fourth quarter of 2012, costs to produce copper and zinc concentrate were allocated based on the refined value of contained metal. Commencing in the current quarter, and going forward, costs to concentrate will be allocated between copper and zinc concentrate based on the value of contained metal net of expected treatment and refining charges. Overhead costs will also be reallocated to better reflect activity levels. As a result of this change, relatively higher costs are assigned to copper concentrate and relatively lower costs are assigned to finished zinc as compared to prior quarters. These changes do not significantly affect overall cash costs.

Cash cost for the full year 2012 was $1.07/lb, compared to $0.45/lb for the full year 2011. Mining, milling and concentrating costs per pound of copper sold were lower in the first three quarters of 2012, compared to the same period in 2011, as a result of lower mine costs at the company's Chisel North and Trout Lake mines. At Hudbay's Trout Lake mine, development costs were lower, so the company needed less ground control work and used fewer consumables. At the company's Chisel North mine, the mining method used to extract ore was lower cost as compared to 2011. Net by-product credits decreased in the fourth quarter due to the stream agreement, increasing the average cash cost for the year.

Note to United States Investors

Under Securities and Exchange Commission (the "SEC") Industry Guide 7, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time of the reserve determination, and the SEC does not recognize the reporting of mineral deposits which do not meet the United States Industry Guide 7 definition of "Reserve".

In accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") of the Canadian Securities Administrators, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") Definition Standards for Mineral Resources and Mineral Reserves adopted by the CIM Council on December 11, 2005.

It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Therefore, you are cautioned not to assume that all or any part of an inferred mineral resource exists, that it can be economically or legally mined, or that it will ever be upgraded to a higher category. Likewise, you are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be upgraded into mineral reserves. You are urged to consider closely the disclosure on the technical terms in Schedule A "Glossary of Mining Terms" of Hudbay's annual information form for the fiscal year ended December 31, 2011, available on SEDAR at www.sedar.com and incorporated by reference as Exhibit 99.1 in Hudbay's Form 40-F filed on April 2, 2012 (File No. 001-34244).
