Lalor

The company has invested approximately $412 million at the Lalor project to November 30, 2013 and has entered into an additional $42 million in commitments. The Lalor underground mine remains on schedule and on budget. Underground project development has continued, with completion of the excavation of the production shaft to the 985 metre level. Initial steel guide installation is planned for January 2014. Receipt of the Environmental Act licence, which permits mining from the production shaft, is expected in the ordinary course.

The company is investing $9 million at its existing Snow Lake concentrator to refurbish equipment and facilities and double production capacity to approximately 2,700 tonnes per day by mid-2014, when the production shaft at Lalor is being commissioned. This investment has enabled the deferral of construction of the new Lalor concentrator until 2015. The company has allocated $10.5 million of Lalor's $75 million growth capital budget to continue with engineering and optimization work for the new concentrator during 2014.

Constancia

At Constancia, detailed engineering and procurement were completed during 2013 and the project is over 56% complete to December 31, 2013. Of the total project capital budget of US$1.7 billion, Hudbay has incurred approximately US$932 million in costs to November 30, 2013 and has entered into an additional US$305 million in commitments.

Hudbay is continuing construction activities on the power transmission line from Tintaya to Constancia, with preliminary agreements securing approximately 90% of the land access rights for pylon construction and civil foundations completed on 55% of the tower sites. Mine equipment is being delivered to site on schedule and major haul trucks are currently being assembled. Two of the three hydraulic shovels are in Peru with one assembled and one currently being constructed. All of the mill sections have been delivered to site. Both ball mills have been assembled through trunnions and one SAG mill shell is currently being assembled with the head ends currently being attached. Assembly and installation of the float cells is almost complete with three shells remaining. Hudbay is conducting steel erection at the plant site and productivity is advancing well. Water capture for operations began in December 2013. Foundation work and dam construction on the east tailings facility are underway and on schedule. Bog removal in the tailings facility continues with good productivity and volume assumptions are in line with expectations.

In accordance with the agreements Hudbay has entered into with local communities, the company has delivered new homes to 29 of 36 families and has constructed a total of 32 homes. The relocation of these families is in progress. Negotiations to secure surface rights over the Pampacancha deposit are expected to commence in the near future.

Hudbay has received approval of all required construction permits. It has also obtained approval for the early refund of value added tax on purchases with retroactive effect to December 2012. In the third quarter Hudbay received approval of its Environmental and Social Impact Assessment (ESIA) Modification 1 and submitted an application for a second amendment to the ESIA in December 2013, which would cover the final project configuration and permit the incorporation of Pampacancha into the mine plan. An amendment to the mine permit to allow for mining in accordance with ESIA Modification 1 was approved in December 2013. Also in December 2013, Hudbay entered into a 15-year tax and fiscal stability agreement with the government of Peru. All permitting remains on schedule.

Reed

Of Hudbay's $72 million estimated capital construction budget, the company has invested approximately $59 million on the project to November 30, 2013 and has entered into an additional $5 million in commitments. As of November 30, 2013, project development has advanced 1,662 metres with an additional 417 metres of pre-production development for a total 2,079 metres of advancement.

Initial production was achieved during September 2013. The project is on budget and on schedule and is expected to reach commercial production by the second quarter of 2014.

Exploration Budget

Hudbay has budgeted exploration expenditures of $20.4 million which is almost entirely devoted to brownfield opportunities near the company's existing deposits. A key component of this will be the development of the 955-1025 metre level exploration drift at Lalor during the second half of 2014, which is expected to enable tighter-spaced drilling to upgrade known inferred resources and to test the down plunge exploration potential of the gold and copper-gold zones. Underground exploration drilling at 777 will also continue with the objective of extending the mine life beyond 2021.

In Peru, Hudbay expects to continue exploration activities on the porphyry and skarn mineralization potential of its property near the Constancia deposit. Geophysical activities are currently underway to help define new areas of activity for 2014.

1 Metal reported in concentrate is prior to refining losses or deductions associated with smelter terms. Production volumes include anticipated pre-commercial production amounts from Lalor, Reed and Constancia.
2 Includes 100% of Reed mine production
3 Precious metals production includes gold and silver production. Silver converted to gold at a ratio of 50:1 for 2014 guidance.
4 Reflects combined mine and mill costs per tonne of milled ore. Excludes mine and mill costs and tonnes associated with pre-commercial production mine output from Reed and Lalor in 2014. Constancia unit costs not included as the mine is not expected to be in commercial production during 2014.

Metal production in any particular quarter may vary from the annual guidance rate based on variations in grades and recoveries due to the areas mined in that quarter and other factors. Mining and processing costs in any particular quarter can also vary from the annual guidance rate above based on a variety of factors including the scheduling of maintenance events and seasonal heating requirements. Metal production and costs will also vary from quarter to quarter due to the ramp up of operations at the company's new mines. As in past years, costs in the first and fourth quarters are expected to be higher at the company's Manitoba operations due to additional heating and other seasonal costs.

2014 Production and Unit Cost Guidance Flin Flon Zinc Plant
Zinc concentrate treated	195,000 - 225,000 tonnes
Recovery	97%
Zinc metal produced	100,000 - 110,000 tonnes
Unit Operating Costs 1	C$0.30 - $0.37/lb
1 Forecast unit operating costs are calculated on the same basis as reported unit operating costs in Hudbay's quarterly and annual management's discussion and analysis.

Hudbay's domestic zinc concentrate production in 2014 is expected to result in zinc plant production levels above 2013 results due to higher domestic zinc concentrate production and the availability of third party purchased concentrate. Operating costs at the zinc plant in 2014 are expected to be comparable to 2013 levels.

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 should 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).
