Total capital costs of $343 million
• 2004 - Acquired by EuroZinc
• 2006 - Acquired by Lundin Mining
through merger with EuroZinc
• 2010 - Exploration discovered a
new copper-rich massive sulphide
deposit, Semblana
• 2011 - Zinc plant successfully
expanded to 1.0Mtpa
• 2013 – Achieved annual record zinc
production aided by higher grades
from the Lombador ore body
17
2013 Results
• Production of 56.5kt copper and an annual record of 53.4kt zinc
• C1 costs of $1.90/lb Cu in-line with latest guidance
• Average copper grades of 2.6% with recovery rate of 84.5%
• Copper production exceeded guidance for the year due to higher
than expected throughput, offset by lower recoveries
• Higher zinc grades from initial production in the deeper sections
of Lombador contributed to increased zinc production in H2/2013

Four Mining Methods
• Drift and fill – A very selective mining method used mainly in copper
ore. Employs cemented hydraulic sandfill
• Bench and Fill – Productive bulk mining method used mainly in zinc
and also in copper ore. Employs paste fill in primary stopes and
waste rock in secondary stopes
• Mini Bench – Modified bench and fill method used in zinc and copper
ore. Employs paste fill in primary stopes and waste in secondary
stopes
• Optimized Bench and Fill – Productive bulk mining method used in
zinc ore. Paste in primary stopes and waste in secondary stopes

Three types of Backfill
• Uses mill tailings strengthened with cement. Preferred fill type, good from
environmental perspective, very cheap, capacity being increased
• Hydraulic Sandfill – Uses sand mined from our own quarry strengthened
with cement. Railed to the mine from our own quarry. Expensive and will
be largely displaced by paste in next twelve months
• Waste Fill- Waste rock mined from ore access tunnels. Previously hoisted
to surface for disposal but now mostly is stowed underground
43
Zinc and Copper Treatment
•Copper and zinc ore are handled separately
in the mine and also treated separately
•Zinc plant has a capacity of 1.2Mtpa and
2014 is the first year of full utilisaton
•Copper plant currently operates at 2.3Mtpa
and has capacity for 2.7Mtpa

Production Outlook
• Copper production to remain steady going forward at 50-55kt
• Zinc production expected to increase to 75-80kt by 2015
Notes: LUN three year guidance released on December 4, 2013. Production outlook assumes mid-point of guidance range.
47
Tailings and Water Management
48
Tailings Management System
• The tailings have acid generation potential and have been placed, since
mine start up, sub-aqueously, in a large tailings pond.
• The new method consists of Paste/Thickened Tailings production, uses
latest available technology and is sub-aerially deposited.
49
Tailings Management System – Paste/Thickened Tailings Technology
• The sequential deposition areas are defined by berms or dykes,
built with mine waste rock
• The Paste/Thickened Tailings Technology allows:
– Cover of each area with an engineered cover after filling
– Co-disposal of acid generating tailings and waste rock
– Minimization of acid rock drainage impacts
– Better geochemical and geotechnical stability
– A progressive and concurrent closure of the tailings dam
during operation of the mine.
50
Concentrate Transport and Setubal Port
51
Concentrate Marketing
• All concentrates, both copper and zinc, are sold under long
term contracts directly to mainly European smelters
• The commercial terms under the contracts are negotiated on
an annual basis and the concentrates are sold at the
respective benchmark for copper and zinc concentrates or
better
• Copper Benchmark terms for 2014
– Treatment charge $92/t concentrate
– Refining charge $0.092/lb payable copper
• Zinc benchmark terms for 2013 (negotiations still in progress
for 2014)
– Treatment charge $212/t concentrate based on zinc prices of
$2,000/t with escalators 2-6%, and de-escalators 2%

Concentrate Transport and Setubal Port
• Storage at the mine approximately:
– 20,000t for Copper concentrates
− Built a covered concentrate
warehouse at the mine 2013
– 12,000t for Zinc concentrates
• Concentrates loaded into containers
and railed 180 km to our storage and
shiploading facility at Setubal on
Atlantic Coast
• Sampling for concentrate quality
before it leaves the mine
• Concentrates are typically shipped as
7,000t bulk cargos from Setubal
55
Setubal Port Concentrate Handling
• The Setúbal facility is owned by Somincor and includes warehouses
equipped with mechanised load out and blending equipment
• Warehouse capacity is 27,000t of copper concentrates and 8,000t of
zinc concentrates but the proportions can be adjusted
• From time to time Somincor also loads concentrates for other mining
operations
• Approximately 6 ships are loaded every month primarily for European
Smelters

Investment in Portugal: Fiscal Environment
• High public deficit and inability to independently obtain finance led to
2011 agreement with IMF & ECB to finance Portuguese economy. Three
year program considered a success and planned to finish at the end of
May 2014
• Austerity measures being enforced under the bailout agreement, which
contemplated amongst other things:
– Taxes, such as personal, VAT and Corporate Tax were increased
– Measures to promote economic growth, notably employment measures to grant
more labor contract flexibility
– Reduction in number of annual holidays, public holidays and penalty rates for
overtime
– Reduction in public deficit
• Income Tax Rate – 29.5% in 2014 vs 31.5% in 2013
59
Investment in Portugal: Royalties
ARTICLE 13.1 OF CONCESSION CONTRACT:
In additional to Corporate tax Somincor pays royalties, in
accordance with the latter’s sole criteria and discretion:
a) 10% of annual net profits less all corresponding tax
charges;
or
b) Alternatively, 1% of NSR.

Zinc Expansion Project
• Neves-Corvo zinc orebodies Neves Corvo can yield at up to
3Mtpa of zinc ores whereas we now have 1.2Mtpa plant
capacity
• Current studies are defining the optimum mine and plant
expansions to achieve a sustainable zinc output in the order
of 150,000tpa zinc.
• Two main areas of study are the underground ore and waste
handling (incl. shaft capacity) and the process plant.
– Debottlenecking has increased the shaft output from 2.5Mtpa to
4.9Mtpa, so some expansion scenarios require modest
investments
– A SAG mill was previously acquired for the zinc plant expansion.
