Orca Exploration announces results of independent resource report on the Songo Songo West prospect

    TORTOLA, British Virgin Islands, Sept. 30 /CNW/ - Orca Exploration Group
Inc ("Orca") announces that McDaniel & Associates Consultants Ltd. has
finalised its report on the resource potential of the Songo Songo West
prospect that lies 2.5 kilometres west of the existing Songo Songo field. The
Songo Songo West prospect has a similar geological structure to the Songo
Songo field and is expected to have trapped gas in the same reservoir.
    The report summarises the prospective recoverable resources to be as

    Formation       Unrisked    Unrisked    Unrisked    Unrisked      Risked
                         P90         P50        Mean         P10        Mean
                         Bcf         Bcf         Bcf         Bcf         Bcf
    Neocomian          170.1       418.1       505.2     1,027.9       264.4
    Cenomanian           8.5        31.7        46.4       117.7        16.2
                                               551.6                   280.6

    The prospect is interpreted by McDaniel as having a high geological
chance of success of 52% in the Neocomian and 35% in the Cenomanian
    The size of the prospect compares extremely favourably with the Songo
Songo field that contains total gross 2P recoverable Additional Gas reserves
of approximately 500 Bcf on a life of licence basis (gross to the Company 474
Bcf with an NPV 10 of US$255 million) that is available to be marketed and
sold by Orca under the terms of the PSA with the Tanzania Petroleum
Development Corporation.
    Orca has tendered for a jack up rig with a view to testing the prospect
in 2009. The Company is currently looking for another operator in East Africa
to share the costs of the rig and ancillary services.

    Forward Looking Statements

    This disclosure contains certain forward-looking estimates that involve
substantial known and unknown risks and uncertainties, certain of which are
beyond Orca Exploration's control, including the impact of general economic
conditions in the areas in which Orca Exploration operates, civil unrest,
industry conditions, changes in laws and regulations including the adoption of
new environmental laws and regulations and changes in how they are interpreted
and enforced, increased competition, the lack of availability of qualified
personnel or management, fluctuations in commodity prices, foreign exchange or
interest rates, stock market volatility and obtaining required approvals of
regulatory authorities. In addition there are risks and uncertainties
associated with oil and gas operations, therefore Orca Exploration's actual
results, performance or achievement could differ materially from those
expressed in, or implied by, these forward-looking estimates and, accordingly,
no assurances can be given that any of the events anticipated by the
forward-looking estimates will transpire or occur, or if any of them do so,
what benefits, including the amounts of proceeds, that Orca Exploration will
derive therefrom.
