Management Discussion
"We are very pleased with the results of the Ca�ariaco Norte Pre-Feasibility
Progress Report," stated Sean Waller, P.Eng., President of Candente.
"The work completed by Candente and AMEC during 2010 certainly
demonstrates the very attractive technical and financial parameters of the
Ca�ariaco Norte project. With the significant increase in the size of the
resource announced late last year, a solid scope of development and robust
financials, Ca�ariaco Norte is rapidly evolving into one of the premier
undeveloped large scale copper projects in the world - with the added benefit of
being located in Peru."
The Ca�ariaco Norte project offers many advantages. It is reasonably close to
key road and power infrastructure, has a low strip ratio, soft rock, low
operating cost, offers excellent potential for discovery of additional
resources, and is located in Peru, one of the most favourable countries in the
world for mining project development.
Candente advises readers that additional geotechnical drilling and rock quality
assessment is required to complete the open pit slope design to a level
consistent with generally accepted prefeasibility requirements. Due to the
preliminary level of pit wall design, this report does not meet the criteria of
a Pre-Feasibility Study and therefore is classified as a Pre-Feasibility
Progress Report.
The above ground structures in the tailings management facility
("TMF") have been designed to a pre-feasibility level, however
geotechnical investigations in the TMF area have not been completed and as a
result there is a risk that the TMF design may require revision. The remainder
of the Pre-Feasibility Study Progress Report does however meet a
pre-feasibility level of assessment, and Candente is satisfied that this report
provides sufficient level of project development to justify advancement to a
Feasibility Study.

Financial Analysis
The Net Present Values of the Ca�ariaco Norte project at various copper price
points and discount rates are presented below. Candente has selected as the
Base Case a long term copper price of US$2.25 /lb. The financial model applied
by AMEC utilizes a reverting price curve whereby metal prices in the early
years of operation are higher and gradually decrease to fixed long term prices
after year 10. This approach recognizes the industry consensus view that future
copper and precious metal prices will remain higher than historical price
trends over the short to medium term, with reversion to lower long term prices.
For the Base Case with year 1 production anticipated in 2015, the initial
copper price is US$2.92 /lb reverting to US$2.25 /lb after year 10; a gold
price of US$1,159 /oz reverting to US$1,015 /oz; and a silver price of US$20.96
/oz reverting to US$15.85 /oz.
As of January 2011, AMEC is applying long term metal prices of US$2.40 /lb
copper, US$1,015 /oz gold and US$15.85 /oz silver. The Ca�ariaco Norte project
is highly leveraged to the price of copper. At long term copper prices of
US$2.40 /lb and above, the after tax NPVs and IRRs increase significantly.

The financial model is based on open pit mining by the owner with leased supply
of mobile mining equipment including scheduled additions and replacements. All
other project costs are the responsibility of the owner including process and
infrastructure preproduction capital, life-of-mine sustaining capital, and
closure costs. Peru corporate income tax of 30%, employee profit sharing tax of
8% and the Peru mineral production royalty is applied on a sliding scale of 1%
to 3% according to revenue levels. Depreciation on capital equipment as
permitted by Peru tax regulations has been applied. Finance charges for project
construction capital have not been applied in the model.
The mine plan is based on Measured and Indicated mineral resources only, with
Inferred mineral resources considered as waste. Mineral resources that are not
mineral reserves do not have demonstrated economic viability.
Capital Costs
Preproduction direct capital costs for the 95,000 tonnes per day project are
estimated to be US$904.6 million which includes US$171.9 million for mine
preproduction development, US$381.3 million for process plant, US$101.5 million
for tailings management facility, US$26.9 million for concentrate storage and
handling facilities at the load-out port, and US$223.0 million for
infrastructure including diversion channel, access road, and connection to the
national power grid. Indirects, owner's cost, and contingency total US$532.5
million.
The capital cost estimate is predominantly based on 3rd quarter 2010 costs. In
addition to the capital cost, the financial analysis includes owner's
preproduction costs of US$52.9 million, working capital of US$65.7 million,
sustaining capital and closure costs of US$128.1 million.

This updated mineral resource estimate is based on 230 drill holes and includes
the results of 16 drill holes completed after the previous estimate by SRK
Consulting (Canada) Inc. in September 2008, as well as a review of the deposit
lithology, alteration and specific gravities. Metal prices used by AMEC for the
updated resource estimate are: copper US$2.50 /lb, gold US$1,035 /oz and silver
US$17.25 /oz.
Mining
The Ca�ariaco Norte copper project will see development of a large scale open
pit mine utilizing conventional truck and shovel mining. The mine plan calls
for the extraction of 728.2 million tonnes of mineralized material and 713.5
million tonnes of waste over the projected 22 year mine life (strip ratio of
0.98 to 1). Average life-of-mine head grades to the process plant will be 0.40%
copper, 0.067 g/t gold and 1.71 g/t silver. Importantly, the mine grades during
the first three years of production will be higher, with average feed grades of
0.48% copper, 0.086 g/t gold and 2.14 g/t silver.
The open pit mine design relating to the angle of the pit wall slopes has been
developed based on geotechnical logging of drill core plus rock quality
evaluation and compressive strength testing of a limited number of core
samples. The amount of geotechnical data available is not sufficient however to
support development of a pre-feasibility level design for the pit wall slopes.
As a result, the mine plan developed for this report must be considered to be
at a preliminary level.
In the absence of sufficient geotechnical data AMEC has applied overall pit
slopes of 35 degrees on the high west wall and south wall, and 44 degrees on
the lower north and east walls. Additional geotechnical drilling in the pit
area is required to permit a pre-feasibility and feasibility level pit wall
design. Candente plans to complete the required geotechnical drilling and rock
quality testing as part of a Feasibility Study program.
Metallurgy and Process
Grinding and flotation test work was performed by SGS Lakefield located in
Santiago, Chile, under the direction of Transmin Metallurgical Consultants in
Lima. Preliminary concentrate roasting test work for the removal of arsenic was
conducted by Outotec Oyj in Sweden.
The metallurgical test work confirms that conventional crushing, grinding and
flotation technologies are appropriate for the recovery of copper, gold and
silver from the Ca�ariaco Norte deposit. The preliminary concentrate roasting
test work supports the application of this technology for the reduction of
arsenic in the Ca�ariaco Norte concentrate.
Processing will utilize primary crushing, semi-autogenous and ball mill
grinding for size reduction followed by rougher and cleaner flotation for
copper recovery and production of copper concentrate. The copper concentrate
will then be subjected to a partial concentrate roast process at site to reduce
arsenic levels and improve the marketability of the copper concentrate.
Final copper concentrate will be trucked to a load-out port facility near Eten
in Northern Peru for ocean shipment to offshore smelters. Sulphuric acid
produced as a by-product of the roasting process will be upgraded and sold to
consumers in western South America. Process tailings will be contained at the
project site in a facility design for long term tailings management.
Water Management
Candente management recognizes and fully respects the importance of water to
both the daily lives of the surrounding communities and agricultural projects
downstream. For Ca�ariaco Norte, a controlled water management system has been
developed and preliminary engineering studies indicate that the Ca�ariaco Norte
project will have minimal impact on the local water resources.
Local ground water and surface water courses within the proposed mine area are
expected to be adequate to supply the majority of water required for the
proposed mine operation. Discharge of water to the environment is anticipated
only after project closure. The water management system will ensure that
discharge streams meet the appropriate Peruvian regulations for water quality
and be suitable for downstream agricultural usage. As part of the next phase of
project engineering study Candente plans to work with the local community to
assess opportunities for the provision and distribution of water for
agricultural purposes.
Environment and Community
Development of the Ca�ariaco Norte project would result in a significant
increase in local and regional employment opportunities and would generate
significant ongoing expenditures to regional and national suppliers for goods
and services required for mine operation. Furthermore, the Ca�ariaco Norte mine
would provide a substantial long-term addition to the tax base for the
Lambayeque region.
In keeping with world best practice, Candente intends to follow the Equator
Principals and World Bank Standards for the proposed mining development at
Ca�ariaco Norte. These
protocols outline best practices for developing projects with regard to
protecting the environment, biodiversity and managing social impact.
Permitting Advances
Environmental and Social Impact Assessment ("ESIA") studies have been
underway since 2007 with AMEC Peru S.A., an internationally recognized
environmental consultant in Lima. The assessment is ongoing but at this point
there are no findings that suggest the project would not meet environmental
approval. Candente has received several permits for certain aspects of
Ca�ariaco Norte development and previously received a Certificate from the
Peruvian National Institute for Culture confirming that no archaeological
remains exist in the area of the Ca�ariaco Norte pit.
Timeline
The proposed timeline for project development to production is scheduled to be
approximately four years after commencement of a Feasibility Study.
Opportunities
Based on the work completed to date there are several significant opportunities
that may offer the potential to further enhance the Ca�ariaco Norte project
including:
The mine plan for the first 18 months of operations may be optimized to
maximize the IRR and reduce project payback period.
The Ca�ariaco Norte deposit is open to depth and the potential exists for the
mine life to be extended beyond the 22 years proposed in this report and/or the
mining and processing rate to be increased. Both opportunities offer the
potential to enhance the economics of the Ca�ariaco Norte project.
The potential exists to discover and delineate additional resources at the
Ca�ariaco Sur and Quebrada Verde targets which are located approximately 1.5
kms and 3.5 kms south of the Ca�ariaco Norte deposit. These targets are located
within Candente's Ca�ariaco property and, should an economic deposit be
delineated at either site, it is possible that development would utilize the
proposed Ca�ariaco Norte facilities.
Risks
As with most projects at this level of assessment, risks exist that may affect
the development of the project. Factors that could pose a risk to the Ca�ariaco
Norte project include changes in world commodity markets, equity markets, costs
and supply of labour and materials relevant to the mining industry, extent of
resources actually contained in mineral deposits, geotechnical conditions,
actual recoveries achieved in processing ore, marketing of concentrate,
technological change, water management, local community opposition,
environmental permitting, change in government and changes to regulations
affecting the mining industry.

CAUTIONARY NOTE TO U.S. INVESTORS
We advise U.S. investors that this news release uses terms that are not
recognized by the United States Securities and Exchange Commission
("SEC"), including "mineral resources", "measured
resources", "indicated resources" and "inferred
resources". The estimation of measured and indicated resources involves
greater uncertainty as to their existence and economic feasibility than the
estimation of proven and probable reserves. U.S. investors are cautioned not to
assume that mineral resources in these categories will be converted to
reserves. The estimation of inferred resources involves far greater uncertainty
as to their existence and economic viability than the estimation of other
categories of resources. U.S. investors are cautioned not to assume that
estimates of inferred mineral resources exist, are economically mineable, or
