Inmet Announces Basic Engineering Results and Financing Plan for the Cobre Panama Project

Sunday, May 06, 2012

Inmet Announces Basic Engineering Results and Financing Plan for the Cobre Panama Project18:34 EDT Sunday, May 06, 2012TORONTO, CANADA--(Marketwire - May 6, 2012) - Inmet Mining Corporation (TSX:IMN) (Inmet) is pleased to announce the completion of Basic Engineering for the Cobre Panama project and the launch of a financing plan to fully fund Inmet's 80 percent share of the related development costs. The Cobre Panama project, located in the Donoso District of Panama, is owned by Minera Panama, S.A. (MPSA), an 80 percent owned subsidiary of Inmet. Cobre Panama is one of the largest undeveloped copper porphyry deposits in the world. MPSA has completed the most important steps of permitting and Basic Engineering, and is now ready to start construction. Korea Panama Mining Corporation (KPMC), a consortium of LS-Nikko Copper Inc. and Korea Resources Corporation, owns 20 percent of MPSA and is our partner in the project. Upon closing of the proposed offering of senior, unsecured notes described in a separate press release issued today, Inmet would authorize the issuance of a "Full Notice to Proceed" for major construction.Jochen Tilk, Inmet's President and CEO said "Inmet has been involved in the development of Cobre Panama for the past 20 years. Since the early days, three separate areas of advancement have converged to strengthen our commitment: first, the deposit has grown substantially; secondly, the communities in the area have participated in and supported the development plans; and finally, Basic Engineering has presented a clear execution strategy. We have focused on the social and environmental commitments for this project as it is our priority to ensure the protection of these values. The results of Basic Engineering have demonstrated robust economics, and we are executing a solid financing plan that does not include issuing equity. The coming four years will be transformative for Inmet as we expect to grow significantly as a low cost copper producer." We will hold a conference call and webcast with a PowerPoint presentation tomorrow, May 7, at 8:00 am ET to provide you with further detail on Cobre Panama.

The capital estimate does not include any amount for escalation.Sustaining capital, including a third line expansion operating from Year 10 onward, is estimated to be US$ 2.92 billion for the estimated 31-year life of mine and includes replacement of mobile equipment, tailings facility development, and water management systems. If we move forward with Full Notice to Proceed in May, we expect total capital spending (on a 100 percent basis) excluding changes in net working capital and interest on long-term debt to be $885 million in 2012.Operating Costs Operating costs are estimated to be US$ 6.88 per tonne of ore milled with mining costs benefitting from a low life of mine strip ratio of 0.58 tonnes waste per tonne of ore. The power cost would be US $1.01 per tonne of ore milled, or 4.4 cents per kWh (LOM) and 2.7 cents per kWh in the first nine years of mine life if we sell excess power back to the grid.

With C1 cash costs over the life of mine at US$ 0.82/lb and total C3 costs of US$ 1.47/lb, Cobre Panama would rank as one of the lowest cost future copper producers in the world.Third Party Reviews Inmet recognizes the industry trend of escalating costs as a significant risk and has commissioned numerous third party reviews to ensure the quality and reliability of the estimates, and to mitigate this risk. Independent reviews encompassed:Capital cost estimates Operating cost estimates for both process and mining Project schedule Compliance with the International Finance Corporation Performance Standards on Social and Environmental Sustainability Tailings management facility Project controls Project execution readinessThe results of these studies confirmed the conservative cost assessment as well as the overall execution readiness of the project. These are summarized in the Basic Engineering Summary Report at Early Commitment and Securing Long-lead Items To reduce exposure to capital cost escalation, we expect to have committed in excess of 50 percent of the estimated capital by the end of 2012.The power plant has already been contracted under a lump sum, turn-key contract to SK Engineering & Construction Co. Ltd., a Korean engineering and construction firm, that has already secured suppliers for long-lead items such as Boilers, Steam Turbine Generators, and Flue Gas Desulphurization systems. The detailed engineering and construction for the process plant would be contracted in the third quarter this year under an Engineering, Procurement and Construction arrangement and the bidding process is currently underway. The SAG mills, ball mills and wrap-around drives have been ordered, and are currently being fabricated with delivery expected next year. The balance of project infrastructure is under contract with Joint Venture Panama (JVP), a joint venture led by SNC Lavalin Group Inc. (70 percent), with partners Techint International Construction Corp. (15 percent) and GyM.S.A., a member of Graña y Montero Group (15 percent) under an Engineering, Procurement and Construction Management agreement that was executed in November 2010. JVP's procurement activities are well underway and would result in the early award of all major earthworks, site capture, camps and site services packages during the second quarter this year. Procurement of the initial mine fleet is well underway and we expect to make a commitment by the third quarter this year.Strategic Decision on Ownership and Financing Plan Recent Project Milestones Over the past years, Inmet has constantly evaluated the appropriate ownership level in Cobre Panama, balancing the growth opportunity presented by future copper production against the capital and execution risk. As our evaluation advanced, the parallel progress in Cobre Panama has substantially lowered the risk and Inmet's capability to fund has increased significantly. The following milestones have facilitated our assessment, and have increased the project's value while reducing financing and execution risk:The completion of Basic Engineering in April 2012 resulting in favourable economics for the project The development of a sound financing plan The approval of the Environmental and Social Impact Assessment (ESIA) on December 28, 2011 The closing of the KPMC option exercise on April 24, 2012 The discovery of Balboa in connection with a substantial increase in mineral reserves and resources and the prospect of future discoveries The establishment of a large and experienced owner's team The establishment of a highly experienced and competent project execution team by Joint Venture Panama (JVP), Inmet's Engineering, Procurement and Construction Management (EPCM) contractor on the project The award of the power plant under a lump sum, turn-key contract to a reputable contractor The completion of all necessary negotiations and resettlement planning with those who will be economically or physically displaced by the development of the projectOn that basis, we believe our best course of action to enhance value is to initiate development with an 80 percent ownership interest in MPSA. As construction advances, we will continue to evaluate opportunities to optimize our holding, balancing the potential benefits of reduced ownership against exposure to this world class copper asset.Financing Plan As announced today by separate press release, Inmet intends to offer an issuance of US $1 billion principal amount of senior, unsecured notes. We have also commenced a process to consider a precious metals stream transaction. We are currently engaged in discussions with interested parties to sell a portion of future gold and silver production attributable to our 80 percent interest in Cobre Panama. If we are successful in completing such precious metals stream transaction on acceptable terms, the stream transaction would provide an additional approximately US$1 billion for our share of the capital cost of the project. The total project funding plan along with the approximate proportion of funding in place is outlined in the table below:(US$ billions)% financedCapital estimate$6.2Funding sources:KPMC$1.423%Inmet cash on hand1.750%Inmet senior unsecured notes1.066%Inmet precious metals stream1.082%Inmet cash flow from operating mines 2012 to 2015 net of financing costs1.5106%Other1.0123%Total Funding Sources$7.6123%Funding classified as "other" represents steps to create additional financial flexibility and to further mitigate financial risk, including:Sale of additional equity in the project Project level debt financing, including off-take financing and equipment lease financing Corporate level debt financing, including a corporate revolving credit facilityChange of Functional Currency to US Dollar The development of Cobre Panama would significantly increase Inmet's exposure to the US dollar considering:Inmet's share of the development costs for the project, the vast majority of which are denominated in US dollars; and our expected issuance of US dollar denominated high yield bonds.On completion of the proposed offering of senior, unsecured notes and authorization for a Full Notice to Proceed, the functional currency of Inmet would become the US dollar effective May 31, 2012, and Inmet would report its financial results in US dollars beginning in the second quarter of 2012.Project Execution Project teamOur qualified and experienced owner's team now comprises 50 members, and would grow to 107 by 2013. This team comprises senior, seasoned individuals with extensive experience in mining and large project development. Profiles for key personnel are included in the Basic Engineering Summary Report. In addition to the owner's team, JVP has mobilized an equally qualified team of 154 members that would peak at 361 in 2013.Current Activities Approved early works are currently underway, including the upgrade of the 40-kilometre Llano Grande road from the Pan-American Highway to the project site. This upgrade incorporates enhanced drainage features, reduced longitudinal slopes and new bridge structures. Three other roads are under construction, and will provide ready access to the site while bypassing local communities to minimize the impact of increased traffic flow. We have received permits and started construction of camps to house up to 2,000 workers by the fourth quarter this year. At the port site at Punta Rincon, we have received the required permit for the installation of a temporary landing barge which will facilitate access for equipment, materials and personnel coming from the port of Colón.Development Plan Cobre Panama would be developed as a conventional truck and shovel open pit mine with a concentrator that employs proven technology (crushing, grinding, and flotation) to produce copper-gold and molybdenum concentrate. A 300 megawatt coal-fired power plant and ship loading port facilities would also be part of the project. A series of analyses were conducted to determine economic pit limits and the mining phase development sequence for three mineral deposits in the concession area: Botija, Colina, and Valle Grande. The concentrator site would be centrally located within two kilometres of all three deposits as well as the stockpile. A fourth smaller deposit, Medio, is roughly 500 metres 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 to 14. Neither the Balboa nor Brazo deposits are incorporated into the mine plan, and represent expansion upside and potential justification for an early expansion of the third line. A third grinding circuit could be added to the concentrator that would commence operation in Year 10, increasing the base ore processing rate from 160,000 tonnes per day to 240,000 tonnes per day. Mine operations would be scheduled for two 12-hour shifts per day, 365 days per year. Four rotating crews would provide continuous operator and maintenance coverage in the mine. The concentrator would operate an estimated 31 years, including the processing of about 193 million tonnes of stockpiled ore during Years 28 to 31.Project Timeline and Milestones Project timelines cited below are subject to permitting and approvals, and will be confirmed in our ongoing reporting.
