Total Resource for Kipoi Project increased by 47% - Inferred Mineral Resource expands to 644,000t contained Copper Metal, 22,600t Cobalt and 2,788,000oz Silver



    PERTH, Western Australia, April 16 /CNW/ - Perth-based emerging copper
miner Tiger Resources Limited ("Tiger" or the "Company") (ASX/TSX: TGS) is
pleased to report a significant increase in minerals resources for the Kipoi
Copper Project (the "Kipoi Project" or the "Project") in the Katanga Province
of the Democratic Republic of Congo ("DRC").
    Maiden Inferred Mineral Resource estimates have been completed for the
Kipoi North and the Kileba South deposits. The two deposits are located within
the boundaries of the Kipoi Project area which contains a 12 km sequence of
mineralised Roan sediments that also hosts the Company's flagship Kipoi
Central deposit.
    The new Mineral Resources are shown in the attached tables.

    
    Highlights

    Total Inferred Copper ("Cu"), Cobalt ("Co") and Silver ("Ag") Mineral
    Resource for Kipoi Project increases to 644,000t of Copper, 22,600t of
    Cobalt and 2,788,000oz of Silver.

    Increase in Copper represents a 47% growth in the resource base.

        Kileba South Inferred Mineral Resource
    -   9.5 M tonnes at 1.40% Cu containing 133,000t of contained copper
        metal.

        Kipoi North Inferred Mineral Resource
    -   5.3M tonnes @ 1.36% Cu and 8.1g/t Ag containing 71,600t of copper
        and 1,372,000 oz of silver.

    -   Mineralisation outcrops at both deposits, and the deposits are suited
        to open pit mining operations with potentially low strip ratios.

    -   Both resource estimates represent predominantly oxide mineralisation
        which would support a Solvent Extraction and Electrowinning ("SXEW")
        operation.

    -   At both deposits further mineralisation has been intersected in
        additional holes, but mineralisation is not yet defined adequately to
        include in the resource.

    -   Further potential exists at both deposits for lateral oxide
        extensions and the deposits are open at depth with substantial scope
        for expansion of sulphide resource.

    -   Kipoi North and Kileba South are in close trucking proximity to Kipoi
        Central offering synergies and efficiencies for future mining
        operation

    -   A revised Mineral Resource estimate for the Kipoi Central deposit is
        in progress and expected to be released in the third quarter 2009.
    

    The Company considers the increase in resources to be extremely
significant as it has the potential to support the development of a long life
mining operation at Kipoi.

    Background

    The Kipoi Project is located 75km's northwest of Lubumbashi, the
Provincial Capital of the Katanga Province in the DRC and covers an area of
55sqkm. Contained within the boundaries of the Project area is a 12km long
fragmented sequence of mineralised Roan sediments that host at least 5
Copper/Cobalt deposits.
    The Company's objective has been to develop a mineral resource base
sufficient to support a future long term copper production capacity of up to
100,000tpa through a clearly focussed exploration and development programme.
    In March 2008 the Company announced its Maiden Inferred Mineral Resource
estimate for its flagship Kipoi Central deposit of 13.4Mt at 3.3% Cu
containing 439,000 tonnes of copper, 20,000 tonnes of cobalt and 1,416,000
ounces of silver. A part of the Kipoi Central Inferred Mineral Resource was
upgraded to a Measured and Indicated Classification in June 2008 which formed
the basis of the Definitive Feasibility Study (DFS) completed in September
2008.
    During 2008 the Company also undertook extensive diamond and RC resource
drilling on the Kipoi North and Kileba deposits.

    Mineral Resource Estimate for Kipoi North

    The Kipoi North deposit is located less than 1km to the north of Kipoi
Central. Mineralisation at Kipoi North is hosted within an uplifted fragment
of dolomites and shales belonging to the Lower Roan Group (Mine Series - R2),
which is host to many of the major copper deposits in the Katangan Copperbelt;
including Kolwezi, Tenke Fungurumwe and Kinsevere. Resource drilling at Kipoi
North has tested mineralisation to sub-vertical depths of up to 200m over a
strike of 650m. Average depth of oxidation is approximately 150m below
surface. The mineralisation remains open along strike and at depth. The
Mineral Resource is subdivided into two main mineralised domains, a
Stratabound domain consisting of a laterally continuous R2 sequence and a
Footwall domain. High grade mineralisation is also hosted in a hangingwall
sequence but was not included in the resource estimate as this mineralisation
has not yet been adequately defined. The average width of the mineralization
is highly variable being wider near surface and narrowing at depth. Average
estimated true width of mineralization is approximately 50m.
    The Mineral Resource estimate is based on the results of 52 diamond holes
(6,820 metres) and 16 reverse circulation ("RC") holes (1,665 metres) for a
total of 8,485 metres. Cube Consulting Pty Ltd has estimated the following
Inferred Mineral Resources for Kipoi North:

    The following key points summarise the modelling method:

    -   Mineralised domain interpretations were based on a combination of
        detailed geological modelling, alteration characteristics and grade.
        Lower grade cut-offs used to limit mineralised domains were typically
        greater than 0.3% copper;

    -   Statistical analysis of 2.5 metre downhole composite data. High-grade
        assay cuts were applied where appropriate;

    -   Data was domained by host lithologies and weathering classification;

    -   Variography was used to characterise the spatial continuity within
        the mineralised domains and to determine appropriate estimation
        inputs to the interpolation process;

    -   3D block models were generated for each domain in Kipoi North. The
        block model was constrained by the interpreted mineralised volumes;

    -   Grade interpolation was carried out using Ordinary Kriging (OK) into
        25mN x 25mE x 5mRL parent cells;

    -   Search strategies were optimised using quantitative kriging
        neighbourhood analysis;

    -   Flagging of oxide, transitional and fresh material and assignment of
        density;

    -   Model depletion by best available topographical surface.
    

    Mineral Resources Estimate for Kileba South

    The Kileba South deposit is located within the boundaries of the Kipoi
Project, 7km to the south east of Kipoi Central. The Kileba South deposit is
hosted near the eastern end of the 12km sequence of mineralised Roan sediments
that fall within the Project area, in the same mineral sequence that hosts
both the Kipoi Central and Kipoi North deposits. Mineralisation at Kileba
South is hosted in sedimentary rock of the Upper R.4 (Mwashia) sequence of the
Roan Group of the Katanga Sequence, similar to the Kipoi Central copper
deposit. Mineralisation at Kileba South occurs within two northwest-striking
and southwest dipping mineralisation zones. The south-eastern mineralisation
zone is a structurally controlled copper ore body, dipping steeply to the
southwest with a strike length of 730 metres. The mineralisation includes
copper sulphide mineralisation below the base of oxidation and copper oxide
mineralisation above it. The depth of weathering is to about 120 metres
vertical depth below surface. At depth, the sulphide mineralisation is
structurally controlled and hosted by a regional northwest-trending fault
breccia. Above the base of oxidation, weathering of sulphides has led to
lateral dispersion of secondary copper minerals, generating a supergene
blanket 700m long by up to 130m wide, and 120m deep. The majority of the
reported Mineral Resource resides within the oxide profile.
    Primary sulphide mineralisation is open at depth and has currently been
modelled to a vertical depth extent of 270m. The mineralisation is also open
to the northwest.
    The Mineral Resources estimate is based on the results of 38 diamond
holes and 40 RC holes for a total of 10,984.55 metres. CSA Global Pty. Ltd.
has estimated the following Inferred Mineral Resource for Kileba South:

    Mining Development

    There are five known copper deposits hosted in a 12km long fragmented
sequence of mineralised Roan sediments that have been mapped within boundaries
of the Kipoi Project in which the Company is earning a 60% indirect interest.
    The Company proposes a staged development at the Kipoi Project. The
Company has completed an optimized definitive feasibility study in respect of
a Stage 1 mining, Heavy Media Separation ("HMS") and spiral system operation
to produce 150,000 tonnes of copper concentrate per annum for three years. The
Company has recently commenced a feasibility study to evaluate the economic
viability of constructing an SXEW plant targeted to come on stream within
three years of the start of the HMS operation. It is envisaged that ore from
Kipoi Central, Kipoi North and Kileba South and the other deposits within the
Kipoi project would be processed at the Stage 2 development phase.
