I see the combination of the two companies creating not only a new global leader in copper, but also one of the most exciting, 'must-own' companies in the global mining sector.

We are taking the significant step of making this proposal directly to Inmet shareholders and requesting their support for what, together, we know can be achieved. We invite Inmet shareholders to participate in this vision and to become shareholders in this most exciting new venture."

        expanding copper production footprint with the capacity to deliver,
        according to third party research analyst estimates, in excess of
        1.3 million tonnes of copper production per annum by 2018, which
        would make the combined entity a top five copper producer

    iii.Enhanced financial profile with greater liquidity, greater free cash
        flow generation ability and enhanced flexibility to raise capital
        when necessary at a lower long term cost of capital

--  Creation of a new global leader focused on copper with industry leading
    copper production growth, based upon third party research analyst
    projections, of over 24 percent, compounded annually, from 2012 to 2018,
    driven by a strong pipeline of low capital intensity development
    projects and low cost expansions of existing operating assets.

--  Opportunity to benefit from the implementation of First Quantum's unique
    and proven approach to project construction at the Cobre Panama Project,
    in respect of which Mr. Pascall commented:

    "Our in-house expertise and technical competencies have translated into
    a real competitive advantage. These unique technical capabilities have
    allowed us to construct projects at a fraction of the cost achieved by
    our peers. We deliver on our promises to meet budget, to be on time, to
    attain rapid commissioning to commercial production and to achieve
    absolute production targets. Our commitment is to apply these skills to
    Cobre Panama, creating an opportunity for all shareholders to benefit
    substantially."

A diverse portfolio of profitable operating assets and quality growth projects makes First Quantum one of the fastest-growing mining companies in the word.

First Quantum has earned a strong reputation as an industry leading developer of high-quality base metals projects globally.
