    POSITIVE PRE-FEASIBILITY OUTCOME FOR CLONCURRY COPPER PROJECT

    Results from the recently completed Pre-Feasibility Study have successfully demonstratedboth the technical and commercial credentials of Excos Cloncurry Copper Project

    Production of ~20,000tpa of Cu and ~13,000ozpa of Au over an initial 11-year mine lifegenerates a robust base case project valuation (NPV = A$126M) with significant upside

    On the basis of these positive results the Board intends making an immediate commitment tothe Definitive Feasibility Study phase

    INTRODUCTION

    Exco Resources Limited (Exco) is pleased to provide a summary of results from the recentlycompleted Pre-Feasibility Study (PFS) on the Cloncurry Copper Project (CCP). The PFS commenced

    in December 2007 and initially considered options for a 1 to 2Mtpa sulphide concentrator operationlocated within the Companys Project areas (see Figure 1). The preferred scenario of locating a2Mtpa facility at Excos flagship E1 Camp emerged quite quickly allowing the Company and its StudyManager GRD Minproc to focus on developing preliminary engineering designs, cost estimates andsensitivity analyses for this option, which are summarised below.

    In addition to identifying the optimal capacity and location, the PFS has also provided a solid technicalbasis for the CCP. Aspects such as mining, ore beneficiation, metallurgy (including by-productpotential), infrastructure and transportation have all been addressed. Each of these aspects willreceive more detailed attention during the upcoming Definitive Feasibility Study (DFS).

    In parallel with the PFS the Company has also progressed an environmental impact study (EIS) andcompleted the major portion of an infill drilling program targeting conversion of ~25 million tonnes of

    the existing ~36 million tonnes of CCP resources (see Table 1) to the indicated category (andultimately to a probable reserve) as the basis for the initial 11-year mine life. This drilling andsubsequent resource modelling will be completed during Q3/2008 to allow incorporation into the DFS.

    Project valuations are considered robust and compare favourably with peer projects in Australia.There are also a number of opportunities for significant commercial upside (e.g., further resourceupgrades, pit optimisations, mine planning and scheduling, cost optimisations and by-productpotential), which will all be further investigated as studies continue.

    On the basis of both the technical and commercial credentials of the CCP the Board intends makingan immediate commitment to the DFS, targeting completion by the end of Q1/2009.

    PROJECT OVERVIEW

    Critical Mass ofresources in place

    Simple open-pitmining

    Excos wholly owned Cloncurry Copper Project (CCP) is located in NWQueensland with its centre of gravity at the Companys flagship E1 Camp,approximately 40 km northeast of the town of Cloncurry and 8km east of XstratasErnest Henry Mine (see Figures 1 & 2).

    The CCP includes tenements and mining leases with a resource base in excess of35.8 Mt grading 0.93% copper and 0.25 g/t gold (see Table 1). The sulphidecopper-gold mineralization occurs predominantly within magnetite, pyrrhotite, andchalcopyrite-pyrite mineral assemblages.

    Conventional blast, excavate and haul mining techniques will be utilized to recoverore from open cut pits. The project infrastructure (Figure 2) will be located at theE1 Camp with ore being trucked from Monakoff and Great Australia to aprocessing plant at E1.

    Figure 2: Project layout & proposed infrastructure

    Conventional Cu/Auconcentrator withgood by-productpotential

    Processing of the ores will be by means of conventional crushing, grinding andflotation to produce a sulphide concentrate that will be sold to third parties forsmelting and refining. With an initial 11-year mine life and at a throughput rate of~2Mtpa the project is expected to produce ~20 000 tpa of copper and~13 000 ozpa of gold in a sulphide concentrate. Magnetite, cobalt and uraniumpresent upside potential as by-products.

    Schedule in placetargeting firstproduction in late2010

    Tailings and waste rock will be deposited in surface dumps adjacent to theprocessing plant and respective pits. Water will be sourced primarily from pit de-watering.

    The project is expected to directly employ in excess of 200 people as bothresidential staff and on Fly-In-Fly-Out (FIFO) arrangements. Local contractors willbe utilised during both the construction and operational phases of the project.

    Completion of the Definitive Feasibility Study (DFS) and the Environmental ImpactAssessment (EIS) is planned for the end of Q1/2009. Subject to receipt of therelevant project approvals and permits, and procurement of the necessary longlead items, construction is expected to commence in late 2009, targeting firstproduction in Q3/2010.

    PROJECT SCOPE & PARAMETERS

    JORC CompliantResource Base

    Infill drilling willconvert projectresources to theIndicated category

    GEOLOGY & RESOURCES: The resource base for the Cloncurry Copper Projectis made up of six main deposits located in three different geological settings, threedeposits at the E1 Camp (E1 North, South and East), two at Monakoff (Monakoffand Monakoff East) and one deposit on the edge of Cloncurry at the historicalGreat Australia mine (see Figures 1 & 2).

    The six resources have been estimated using a combination of inverse distanceand ordinary kriging. Each of the resources has been reviewed either byindependent consultants and/or by Excos resource geologists. The resourceshave been classified using the JORC code as either Indicated or Inferred (with aminor amount of unclassified material, depending on the resource). The resourcebase is summarized in Table 1.

    Infill drilling continues targeting conversion of ~25 million tonnes of the existing ~36million tonnes of CCP resources (see Table 1) to the indicated category (andultimately to a probable reserve) as the basis for an initial 11-year mine life. Thisdrilling and subsequent resource modelling will be completed during Q3/2008 toenable incorporation into the DFS.

    Strip Ratio = 4.5:1

    Mining Inventorieslikely to increase

    MINING: The PFS has assessed the economic viability of mining operations at thesix deposits including development of open-pits and the infrastructure required toaccess, mine and dispose of waste rock.

    The study has produced pit designs, inventories, a schedule and costs associatedwith feeding 2 Mtpa of ore to concentrator facility located at the E1 Camp.

    On the basis of work completed during the PFS, mining inventories currently total21.4 Mt of ore at 0.92% Cu and 0.25 g/t Au with an average Net Smelter Return(NSR) value of $35.6/t of ore. The total mining inventory of 117.1 Mt includes95.7 Mt of waste at a strip ratio of 4.5:1.

    Pit optimisations have been carried out assuming a copper price of US$2.00/lb,

    which Exco currently considers conservative.

    Inventories are expected to increase once infill drilling has been completed andsubsequent resource modelling and pit re-optimisation work carried out at a rangeof copper prices.

    PROCESSING & METALLURGY: A number of metallurgical testwork programshave previously been completed on the CCP ores with an emphasis on flotation.The PFS testwork program therefore focused primarily on the comminution sectionwith the overall aim of obtaining sufficient information to develop a robust processflow sheet for a 2 Mtpa copper-gold concentrator.

    Testwork hasdemonstrated goodCu & Au recoveries

    Simple &conventional processflowsheet

    The results show that the majority of samples tested for ore competency arecategorised as hard to very hard favouring the inclusion of a Ball Mill, rather than aSAG mill as part of the comminution circuit.

    The results of the previous flotation testwork can be summarised as follows:

    Most primary sulphide composites float well

    There are indications that the copper minerals are fine in size. Finer primary

    grinds gave an improved copper recovery and concentrate grade Gold recovery is associated with copper recovery, cobalt is associated with

    pyrite

    Regrinding the rougher concentrate achieves higher re-cleaner concentrate

    grades

    Metal recoveries are 92% for primary Copper and 80% for Gold.

    The current process flowsheet incorporates a single processing line, including athree stage crushing circuit, stockpile, reclaim, ball mill in closed circuit with cycloneclassification, flotation, high rate thickening of concentrate and tailings, pressurefiltration of concentrate and truck load-out facilities. Further testwork will beconducted as part of the DFS to refine this design.

    Figure 3: Conceptual Process Flow Sheet

    Existinginfrastructure is wellestablished

    INFRASTRUCTURE & LOGISTICS: Infrastructure development for the projectincludes access and haul roads, water supply, power supply, campaccommodation, the process plant infrastructure and a Tailings Storage Facility.

    Sufficient work has been completed to provide preliminary design information andcost estimates consistent with the level of detail required for the PFS. Furtherdetailed design will be carried out during the DFS.

    Initial transport and logistics studies have been carried out to assess the facilitiesavailable during construction and for product transport. Cloncurry has extensiveinfrastructure serving the town, with good road and rail access, and an airfieldcapable of accommodating mid range (Fokker 100) type aircraft. No major issuesare expected as to the delivery of equipment as the existing infrastructure is welldeveloped.

    Concentrate will be trucked either directly to the Mt Isa smelter as is the case from

    the Ernest Henry operation, or to existing loading sheds in Cloncurry. Theconcentrate would be transferred to rail cars in Cloncurry and moved to the port ofTownsville where it would be transferred to ship for international markets.Queensland Rail has provided quotations for the cost of transporting theconcentrate to Townsville.

    EIS baseline studieswell underway

    ENVIRONMENTAL: An Environmental Impact Statement (EIS) is currently beingprepared for the CCP, according to the requirements of the Environmental

    Protection Act 1994. Potential impacts on the environment due to the constructionand operation of the project will be assessed, and appropriate mitigation strategiesoutlined to minimise environmental harm.

    The following summary describes the progress of the EIS:

    Draft Initial Advice Statement and Terms of Reference have been completed and

    are awaiting submission.

    The wet and dry season flora/fauna assessments have been completed.

    The soil survey has been undertaken and the soil samples are undergoing

    laboratory analysis.

    Noise loggers have been deployed on site to collect data for analysis and

    modelling.

    Air quality, groundwater, surface water, waste rock and cultural heritage are

    progressing with final reports expected in the coming months.

    The following additional baseline studies will be undertaken in the coming months:

    CAPITAL COST SUMMARY

    Capex of A$209M inline with industry

    benchmarks

    Opportunities tooptimise MiningCapex during DFS

    Incremental Capexrequired to increasethroughput andrecover by-products

    The total PFS capital cost estimate for the CCP is ~A$209M. Table 3 provides a

    summary of the CAPEX by area.

    The costs are for a 2 Mtpa Cu-Au concentrator based in the Cloncurry district ofNW Queensland. The costs, which are presented in second quarter 2008Australian dollars, are considered to have an accuracy of 25% and are consistentwith a number of industry benchmarks.

    Major equipment costs are based on budget quotes received from vendors. All

    other items are based on either in-house database information, allowances or

    information obtained from suppliers.

    It is important to note that the Mining CAPEX includes both the costs for mine

    development (pre-strip) and the cost of an owner mining fleet. The treatment of

    these costs will be looked at together with the preferred mining regime (i.e., owner

    mining versus contract mining and dry hire alternatives) during the DFS phase.

    During the DFS the Company will also be investigating the impact of increasing

    throughput from 2 to 2.5Mtpa. Conceptual estimates suggest project costs will

    increase by ~10% for a 25% increase in throughput. Additional Capital Costestimates will also be compiled during the DFS phase in the context of recovering

    by-product magnetite and uranium.

    OPERATING COST SUMMARY

    Opex of A$1.62/lb ofpayable Cu

    Opportunities tooptimise Opex andincrease by-productcredits during DFS

    Operating costs have been developed using the parameters specified in theprocess and mine design criteria. The operating cost estimate (see Table 4) ispresented in second quarter 2008 Australian dollars, and is considered to have anaccuracy of 25%.

    Cash operating costs (before royalties, but after gold credits) are estimated to

    average A$1.51/lb of payable copper.

    Total cash costs (after royalties and gold credits) are expected to average $1.62/lbof payable copper, or $28.66/t of ore treated.

    The operating costs are dominated by power, fuel and labour. Significant attentionwill be given to optimising these specific cost areas during the DFS.

    No additional allowance has been made during the PFS for potential by-productcredits from Cobalt, Magnetite and / or Uranium. These will be further investigatedduring the DFS

    PROJECT FINANCIAL MODEL

    A detailed financial model has been constructed for the project by Exco usingcapital and operating costs developed by GRD Minproc and commodity priceassumptions based on published forward curves, as summarised in Table 5.

    For the purposes of the PFS, the financial analysis has been conducted on aproject basis only. The analysis is on an un-escalated basis and assumes financingby shareholders.

    The principal project case assessed, assumes that the concentrate product is solddomestically to Australian smelters on a CFR (Cost and Freight) basis withassumed off-take terms.

    The base case model includes only copper and gold products.

    The project life of 11 years is based on mining indicated and inferred resourcesdelineated in US$2/lb pit shells.

    The base case NPV of A$126.7 million is considered robust with the projecteconomics and payback period expected to improve during the DFS on the basisof:

    further resource upgrades

    re-optimising pit shells at a range of higher copper prices

    optimising the preferred mining scenario and associated costs, and

    inclusion of additional by-product credits from Cobalt and Magnetite

    The financial model will also be further refined during the DFS to incorporateproject finance arrangements. Preliminary discussions have commenced with anumber of potential project finance partners.

    SENSITIVITY ANALYSIS

    Preliminary sensitivity analyses have been conducted for the project to assess theeffects of changes in key parameters (i.e., copper price, mined Cu grade,concentrate Cu grade, Opex and Capex) on the IRR, NPV and the pre-tax cashsurplus.

    The NPV is most sensitive to the copper price, which is currently assumed to

    average US$2.72/lb over the life of the project, and mined copper grade.

    Figure 4: Pre-Tax NPV Sensitivity

    BY-PRODUCT POTENTIAL

    Magnetite and Cobaltare technicallyrecoverable

    Potential to generatesignificant furtherrevenue

    Recovery of magnetite (Fe3O4) and cobalt has the potential to significantly improvethe project economics. This was not included in the PFS base case but will beconsidered during the DFS.

    High level testwork has been carried out on magnetite recovery indicating thetechnical feasibility of producing a high-grade saleable product, for only incrementaladditional capital outlay (~A$10M). Payability will however be linked to marketingand transport constraints, which require further investigation.

    Testwork has also demonstrated that Cobalt is partially recovered to the copperconcentrate, whilst potential also exists to produce a separate Co-bearing pyriteconcentrate. The payability of the cobalt in either concentrate will depend on off-take terms.

    Table 7 indicates the potential additional value generated by magnetite and cobalt.

    Additional processbenefits from Fe3O4recovery

    In addition to the potential by-product revenue, several inherent process benefitsmay also be realised by the inclusion of a magnetite recovery circuit. These includeadditional copper, gold and cobalt recovery realised by scavenger flotation of thereground cleaner magnetic tails and an approximate 30% reduction in the tailsthickening and storage duty.

    The CCP resource base also contains valuable amounts of uranium. While theQueensland State Government currently prohibits the mining of uranium, it is

    considered possible that future mining may ultimately be allowed, creating theopportunity for a further viable by-product stream. The conceptual processflowsheet (acid leaching of the tailings stream) and economics of uranium recoverywill be more clearly defined in the DFS.

    DEFINTIVE FEASIBILITY STUDY & PROJECT SCHEDULE

    DFS to commenceimmediately

    A deliberatelyaggressive scheduletargeting productionin late 2010

    Exco is well fundedto achieve itsobjectives

    Exco has received a number of engineering proposals to assist in the completionof a DFS for the CCP and, given the positive results generated by the PFS, theBoard intends making an immediate commitment to this next important phase inthe development of the project.

    A preliminary project schedule has been completed considering major milestonessuch as, completion of the DFS and EIS, project approvals, financing, tendering,detailed design, construction, commissioning and project handover.

    Key milestones include;

    Immediate commencement of the DFS

    Completion of the DFS and submission of the EIS by the end of Q1/2009

    A commitment to long-lead items during Q4/2008; the ball mill and vertimillare the two longest lead items, with lead times of roughly 85 weeks.

    Commitment to Project Finance during early 2009

    Completion of the permitting process and receipt of all relevant project

    approvals, which will dictate the critical path of the subsequent constructionand commissioning phases

    Assuming no major delays are encountered in the approvals process it isanticipated that construction may commence in late 2009

    Project commissioning and first production is targeted in late 2010, withproject handover in Q1/2011

    The schedule is deliberately aggressive with a view to expediting production andmaximising the opportunities created for companies such as Exco in the currentcommodity price and supply / demand environment.

    The Company remains well funded to achieve its immediate objectives with acurrent cash position of ~A$20M.
