Forward Looking InformationSecurities regulators encourage companies to disclose forward-looking information to help investors g g p g punderstand a company’s future prospects. This presentation contains statements about Inmet, andInmet’s future financial condition, results of operations and business based on assumptions we makeabout factors that are not within our control but that affect the mining industry generally and ourbusiness in particular, such as metal prices, currency exchange rates, the cost of consumables used atour operations and changes in legal and regulatory requirements among others requirements,These statements are “forward-looking” because we have used what we know and expect today tomake a statement about the future. Forward-looking statements usually include words such as may,expect, anticipate, believe or other similar words. W b li t ti i t b li th i il d We believe th expectations or assumptions reflected the t ti ti fl t din these forward looking statements are reasonable. However, actual events and results could besubstantially different because of the risks and uncertainties associated with our business or events thathappen after the date of this presentation.

Cobre Panama – Achievements to Date• Since our 2010 FEED study we have: Awarded power plant contract p g Completed the resettlement negotiations with local communities Received Panamanian approval of the Environmental & Social Impact Assessment Increased our copper resources Established a highly experienced and competent project execution team Finalized our partnership with LS‐Nikko and KORES Announced debt financing A d d bt fi i Substantial value has been built, and risk reduced 42
Conclusion: Back to Inmet• 20+ years as a builder and operator of underground and open pit mines • Always been a copper stock: 71% of gross sales last year from Cu, and a higher proportion expected this year p pp p g y pp g p y• Expect copper production growth ~ 25% this year as Las Cruces approaches design capacity• Cobre Panama delivers another low cash cost mine in a favourable jurisdiction = 30+ years to come Cu Resource (lbs) per $1,000 invested Inmet Cu Production (MM lbs) 12,703 200%+ , 5,714 4,847 4 847 3,971 3,767 2,950 220 ‐ 250 Inmet Lundin First Quantum OZ Minerals PanAust HudBay 2012 2017 A natural path for Inmet: copper exposure, low cash costs and growth 43
Risks & Opportunities • Quotes to build power plant and processing plant are written on a “Lump Sum” and “Not to Exceed” basis • Quotes are received from audited, sophisticated vendors with balance sheets to manage costs • Quotes are materially conservative – in some cases the labour multiplier (unit of work over unit of time) used for the project is as high as 3X and some of the quotes for individual work packages have small overlaps in scope the project is as high as 3X and some of the quotes for individual work packages have small overlaps in scope • Advanced stage of engineering (overall 38% complete) in combination with the large portion of firm bids received (58%) should further reduce potential for unforeseen costsCost • Panama’s use of U.S. Dollars is another positive characteristic that would reduce material cost escalation Escalation throughout • Engineering, procurement and construction contractors have incentives to stay on schedule and on budget • Received an opinion from a third party review that there is sufficient firmness and conservativeness in the project budget • By the end of 2012, 50% of the project spend is expected to be committed against firm contracts • Actively considering early purchase of bulk commodities for construction 46
Risks & Opportunities (cont’d) • Cobre Panama, while being relatively low grade, would be amenable to large scale mining methods that result in Low Cost Low Cost the efficient handling of ore and waste gProduction • Very low strip ratio, roughly a 20% of the average (0.58 vs. 2.53) for all open‐pit copper mines in 2011from a Low • Proximity to the coast permits the use of a pipeline that travels a short distance, providing a cost efficient method Grade Mine of delivering concentrate to the port • Access to low‐cost, self‐generated power which takes advantage of proximity to a coal source • Inmet has developed three mines within the tenure of the current management (Las Cruces, Cayeli and Troilus)Management • For Cobre Panama, recruited an Owner’s team that has relevant experience in construction and operations and Depth ensured that the engineering, procurement and construction contractors are of a high standard of quality • Approval of ESIA indicative of support at the highest levels of gov’t; derisks entire permitting process significantly • Extensive involvement and cooperation at both the gov’t and community level • Referring to Inmet, Signi Schneider (EDC, Chief CSR Advisor) commented “These companies take a holistic approach to risk and opportunities. They make CSR part of their business strategies. In the mining sector, companies that are acquiring mineral assets don‘t want projects that have put the community offside, where p q g p j p y ,Gov’t & SocialG ’t & S i l there is a high risk that the project may face roadblocks. They also know their financiers require them to get it right early on.” (The Globe & Mail ‐ Jan 1, 2012) • At the community level, the current lack of conflict in the project area indicates that community engagement efforts are working and a recent study shows overwhelming support for the project. • Received free prior and informed consent of the community; engaging the local community through employment p y; g g g y g p y 47

Mining• Mine production schedule was developed to maximize Plan View of Site Infrastructure and Design Pits early revenues and improve overall project returns utilizing early revenues and improve overall project returns utilizing a conventional mining fleet• Ultimate pit plans and mining phase designs have not changed from the FEED completed in March 2010, with the exception of the Medio pit extension• Open pit development sequence has been adjusted to reflect slightly lower effective cut‐off grades that have resulted from increased copper recoveries and higher metal prices used to define ore in the Basic Engineering Study• Concentrator site is centrally located within 2 km of the Botija, Colina, and Valle Grande deposits as well as the stockpile – A fourth smaller deposit Medio is about 500 m A fourth smaller deposit, Medio, is about 500 m northeast of the Colina pit. The new block model incorporates a small Medio pit which was targeted by recent drilling and is part of the mine production schedule in Years 11‐14 49
Processing / Metallurgy• As part of the 2010 FEED study a large sampling and test program was undertaken to bolster the knowledge from previous work and provide insight into the variability of the grinding and flotation response id i i h i h i bili f h i di d fl i – Metallurgy was further optimized with removal of sodium cyanide as a pyrite depressant and refinements to the cleaner circuits• Metallurgical recoveries used for the production forecasts in this study are based on the results from the 2010 FEED metallurgical program as modified by the revised flow sheet test work during Basic Engineering difi d b h i d fl h kd i i i i• Cobre Panama concentrator would use current proven technology to produce clean copper and molybdenum concentrates• Project design is based on an initial ore feed rate of 160k tpd to the processing plant using two grinding lines, each having nominal capacity of 80k tpd. The design also includes an increase to 240k tpd after Year 9 of operations f k d h d l l d k d f f – This potential expansion includes the addition of a second crusher station to source Colina and Valle Grande ore and a third line in the concentrator which includes crushing, grinding, bulk rougher flotation, water and air systems• Process plant is designed to process ore at a nominal head grade of 0 5% Cu and 0 01% Mo with design maximum copper head grade Process plant is designed to process ore at a nominal head grade of 0.5% Cu and 0.01% Mo with design maximum copper head grade of 0.9% Cu and 0.015% Mo• Copper concentrate would be delivered by a 32km slurry pipeline from the mine site to the filter plant located at the port in Punta Rincon• Af After pressure filtration, the dewatered concentrate would be stored and subsequently reclaimed and loaded onto bulk concentrate fil i h d d ld b d d b l l i d dl d d b lk vessels for delivery to international customers 50
Cobre Panama Mineral Resources• Cobre Panama mineral resources (inclusive of reserves) were re‐estimated in early 2012 to incorporate the 171 holes completed since the 2010 FEED study. The bulk of this drilling was focused on infilling the Brazo Deposit and on outlining the 2011 Balboa discovery. The increase in M&I resources reflected moving inferred resources into the indicated category on the Brazo d & fl d f d h d d h deposit and the addition of the Balboa resource. d h dd f h lb The bulk of the increases in the inferred category came from Balboa’s addition to the resource statement. Mineral resources are shown on a 100% basis and are inclusive of mineral reserves.
