• Adjusted EBITDA is a non-IFRS measures which is calculated as income from mining operations plus amortization, depreciation and depletion, inventory write down and stock-based compensation, minus general and administrative and exploration and evaluation costs. Management believes that these measures provide investors with ability to better evaluate underlying performance.

• Net revenues in Q2 2013 decreased 7% to $314M compared to Q2 2012 mainly due to lower metal prices.

• Copper production in Q2 2013 decreased 5% to 56Mlbs compared to Q2 2012. However, copper sales were higher at 69Mlbs compared to 64Mlbs in Q2 2013 due to inventory timing.

TPM [Total Precious Metals] k ozs

2012 Copper equivalent amounts are based on previously announced LOM commodity prices: Cu at $2.75/lb, Ni at $8/lb, Pt at $1600/oz, Pd at US$500/oz, Au at $1000/oz and Mo at $12/lb and excludes the impact of the Franco Nevada Agreement.

Total copper equivalent* production in Q2 2013 slightly decreased to 33.6 k tonnes compared to 33.9 k tonnes in Q2 2012

Decrease in copper production in Q2 2013 due to the completion of production at the Podolsky mine at the end of Q1 2013 accounting for a 2.6 k tonnes shortfall in Q2 2013. Morrison increased production in Q2 2013 by 0.9 k tonnes over Q2 2012.

Increase in TPM production due to higher recoveries and higher gold content realized at Robinson

Total copper equivalent* production in H1 2013 increased to 71.4 k tonnes compared to 66.5 k tonnes in Q1 2012

Increase in copper production in H1 2013 compared to H1 2013 mainly due to 22% increase at Robinson as a result of higher recovery rates and continuous improvement in mill operating practices.

Increase in TPM production mainly due to an increase in TPM at Robinson by 79% or 13.4Kozs from higher recoveries and higher gold content in concentrate.

C1 cash cost decreased due to lower production costs and higher revenues from TPM

Unit cash cost C1 – USD/lb

Lower production costs and increased bi-product revenue at Robinson resulted in a decrease in overall C1 cost from $2.90 in Q2 2012 to $2.23 in Q2 2013.

Higher production volumes at Robinson has a positive impact on overall unit cash cost in H1 2013. Robinson achieved $1.71/lb unit cost in H1 2013 compared to $2.72/lb in H1 2012 due to exceptional

performance at the mill.

• Cu production 22% higher vs. H1 2012 - higher recoveries and increased milling rates

• CAPEX for H1 related to waste stripping and dewatering activity

• C1 cost significantly lower than H1 2012 at $1.84/lb Cu

• Increase in waste mined over Q2 2012 due to acceleration of waste removal in Ruth Pit area to gain access to ore in 2014

• The remainder of 2013 ore production will be from the Liberty Pit with waste stripping focused on the Kimbley and Ruth pushbacks.

Outlook • Production 23% higher vs Q2 2012

from full use of Craig infrastructure.

• Production 7% lower vs. H1 2012 - due to remedial work at the Craig Shaft and lower grades

• Lateral development continued

• C1 cost higher vs H1 2012 due to lower production volume, lower by product revenues and operation of Craig Infrastructure

• Focus on reducing production variability by improving knowledge of orebody

• Main ramp development will continue

• Copper and by-product production is expected to increase over H1

Outlook

Sierra Gorda project

• Project remains on schedule to commence production in 2014

• Overall progress June 30 at 51%

• Detailed engineering phase largely completed for plant, sea water pipeline and tailings storage facility.

• Construction of seawater pipeline and tailings storage facility over 1/4 complete and ~1/3 of the plant construction complete

• Pre-stripping June 30 at 45.3%
