Company") has a joint venture with Tropical Mines Limited ("TML"), a private
company based in Nigeria, earning a 51% interest in the Segilola Gold Project
in Nigeria. The project is considered to be the most advanced gold exploration
project in the country and is held by Segilola Gold Limited ("SGL") with our
joint venture partner TML, a Nigerian company owned by local investors and the
Government.

    Location

    The Segilola Gold Project is located at the village of Iperindo-Odo
Ijesha, near the city of Ilesha in Osun State, Nigeria. The project site is
situated within 600m of a sealed road, 18km south of the regional centre
Ilesha, the local government centre, with a population of 300,000, which is
itself located on a sealed dual carriage way, 120km north east of Lagos (the
principal international entry port and major commercial centre of Nigeria,
estimated population, 16 million).
    Nigeria has a well established petro-chemical industry based in the Niger
River delta and the government of Nigeria, is now in its second term of
democratic rule. The Government has recently established the Ministry for
Solid Minerals Development to administer all mineral assets occurring in
Nigeria other than oil and natural gas.South Western Nigeria Showing the Segilola Project Site and the Ijebu

    The project is the subject of a Mining Lease, ML41 (changed from ML19706)
that covers an area of 46 hectares within an Exploration Licence, EPL39/40
(changed from EPL 13205)) covering 16km(2).
    SGL also successfully acquired the Ijebu Igbo license area which is
located on the same geological trend south west of the Segilola licenses. This
is an additional licence and being newly acquired still has to be included in
the exploration programme.

    Geology

    The geological setting is described as basement gneiss and Proterozoic
schist belt. The known (from previous drill hole information) mineralised zone
extends over an identified strike length of approximately 1000m. The gold
mineralisation is in the form of quartzite veins within a regional shear
system. The veins are invariably steep dipping and are commonly associated
with fractures and localised shear zones. What is commonly called the Iperendo
reef is not one vein but comprises a vein system of several
parallel-silicified zones within the Ile-Ife-Ilesha schist belt.
    The gold mineralisation is known to be closely linked to silification and
phyllic alteration, and to occur together with pyrite and molybdenite. The
gold mineralisation is bound to the vein sections and to the altered wall
rocks thus forming a drillcore indicated ore body with a thickness between 5m
and 28m (average approximately 10m). The gold contents change along strike as
well in dip, grades encountered in the cores vary between (less than)1g/t and
136g/t.
    The concentration of the gold in quartz veins and silicified zones along
major faults and fracture zones is attributed to the Pan Africa thermotectonic
event. The major fractures and shear zones, most with an overall NNE-SSW tend
appear to be a feature of the region. The regional setting is very similar to
the Ashanti and Sefwi systems in nearby Ghana, which have hosted gold
production in excess of 20 million ounces.Project Area Geology - Segilola Prospect
    To view map, please visit: http://files.newswire.ca/578/CGASegilola.docPrior to our interest in the project Nigerian Mining Corporation ("NMC")
and Hansa Geomin, a German resource engineering company, had undertaken
significant work at the site including the following:-   Landsat TM imagery and aerial photography;
    -   Geological mapping @ 1:12500;
    -   1500 soil samples analysed for gold;
    -   520m of costeaning;
    -   100m of exploration adit;
    -   400km ground magnetics;
    -   10km radiometrics; and
    -   2800m of diamond drilling. Holes were spaced 30m apart logged and
        sampled/analysed in 1m intervals.Resource Potential

    An assessment by a leading Australian geological firm (NH Cole &
Associates) in October 1995 included an assessment of the potential ore
reserves at the project.
    A drill indicated gold mineralisation zone has been shown to exist for
950m along strike and to 150m in depth. The drilling to date suggests that a
grade in excess of 5g/t may be achievable.
    The Company has not yet commissioned a technical report on the Segilola
Project, and as such is not in a position to adopt the resource and other
technical information prepared by TML or its consultants, but intends to
prepare a 43-101 compliant technical report once a resource estimate is
prepared by the Company.
    CGA has reviewed the NMC database (hard copy) and the Hansa Geomin
database (digital), determined a common grid and produced plans and sections
detailing all previous drilling and excavations.
    It is apparent that both the up and down dip extensions and those beyond
the 950m strike length have not been tested so the prospectivity for those
areas within the tenements is considered strong.

    Recent Assay Results

    The Turkish drilling company (Spektra Jeotek), is well advanced in the
current 10,000m drilling campaign with over 7,000m already drilled (76 holes).
The drill core is sent to SGS Laboratories Ltd at Tarkwa in Ghana for sample
prep and assay. The most recent set of assay results since those presented in
the December 2008 quarterly report are set out below.TABLE 1 - Recent Assay Results at the Segilola Gold Project
    To view table, please visit: http://files.newswire.ca/578/CGASegilola.docWork has commenced on the resource model. All results to date have been
included in the model and are encouraging, and will initially be used for
in-house resource generation to establish the scope for a feasibility study.

    Additional Potential

    Further trenching has indicated both northerly and southerly extensions.
Current diamond drilling has verified the existence of this northerly
extension. This work has increased the strike length to approximately 1,050m
and it is still open.
    It is expected that additional sampling and drilling may extend the known
mineralised strike length further to the North and South.

    Metallurgical Testing

    The results of the initial metallurgical testwork (bottle roll test) have
indicated that:-   grade of previously assayed samples is correct;
    -   there is a very low value in the residues from the bottle roll test;
        and
    -   from the limited tests a high extraction can be expected.ABOUT CGA MINING LIMITED
