Recommended Merger of Katanga and Nikanor to Create a Leading African Copper and
                                 Cobalt Company



The Boards of Katanga Mining Limited and Nikanor PLC are pleased to announce
today that they have reached agreement on the terms of a recommended Merger of
the two companies. The Merger will create a company with a combined market
capitalisation of approximately US$3.3 billion and the potential to become by
2011 Africa's largest copper producer and the world's largest cobalt producer.

Summary

*      The Merger will bring together the adjacent properties in the Democratic
Republic of Congo (DRC) owned by Katanga and Nikanor, which were previously part
of the same mine complex, to create a major single-site operation.

*      Substantial high-grade resources of both copper and cobalt will create an
exceptional foundation for a large-scale, low-cost and long-life operation.

*      Based on work completed to date, the Merged Company intends to develop a
unified mine complex with annual output approaching 400,000 tonnes of copper and
40,000 tonnes of cobalt by 2011. It is believed that the combined operations
will be the largest single-site project in the world producing both copper and
cobalt.

*      The Merger is expected to deliver significant value enhancement for
shareholders of both companies resulting from capital savings, lower unit
operating costs and increased production.

*      More cost effective operations are expected to increase revenue to the
DRC government. The coordination of the Merged Company's infrastructure spend
and corporate social responsibility activities will also be more effective in
producing positive change for the communities surrounding the operations.

*      Officials in the DRC have been kept apprised of the potential Merger and
have expressed their support.

*      The Merger will be implemented by way of an offer by Katanga for Nikanor
together with a Cash Return to Nikanor Shareholders of US$452 million.

*      The Merged Company will be well-funded, with a pro forma cash balance of
approximately US$745 million as at 30 September 2007, after taking account of
the Cash Return.

*      The Merged Company will follow Katanga and Nikanor's existing strategies
of financing their projects through a mixture of debt and equity. The level of
additional financing required will be determined as part of a combined business
plan, but it is expected that production from Katanga and a phased approach to
capital expenditure will result in a lower and delayed requirement for
additional financing than for Nikanor standalone.

*      Katanga has received irrevocable undertakings to support the Merger and
accept the Offer from Glencore Finance, RP Capital Entities with interests in
Nikanor Shares, Oakey Invest Holdings Inc. and Pitchley Properties Limited
representing 78.4 per cent. of Nikanor Shares in issue.

*      Nikanor has received irrevocable undertakings from Arthur Ditto, Tain
Holdings Limited, George Forrest and RP Capital Entities with interests in
Katanga Shares representing 48.1 per cent. of Katanga Shares in issue to support
the Merger and not to accept any competing proposal.

*      In addition, Arthur Ditto and Tain Holdings Limited have undertaken to
vote in aggregate in respect of 6,843,000 Katanga Shares, representing 8.7 per
cent. of Katanga Shares in issue, in favour of the Merger at the Katanga
extraordinary general meeting.

*      The Merged Company will be led by Arthur Ditto as President and CEO
supported by executives to be drawn from both companies.  An integration
committee consisting of four members, two from Katanga and two from Nikanor,
will be set up to oversee the integration of the two businesses.

*      The Merged Company, which will retain the name Katanga Mining Limited,
will make an application to obtain a primary listing on the Main Market of the
London Stock Exchange within 5 months of the Effective Date.  The Merged Company
will therefore have primary listings on the TSX and the Main Market of the
London Stock Exchange.

Arthur Ditto, proposed President and CEO of the Merged Company, stated: "
Combining the assets of Katanga and Nikanor will create an industry leader in
both copper and cobalt. We believe it offers the opportunity for a dramatic
increase in value for shareholders of both companies and is a transaction where
the whole is definitely greater than the sum of the parts.  Transacting the deal
now gives us the best opportunity to lower the overall capital spending and
deliver maximum benefit from a consolidated suite of operations. We will have a
much more efficient business model with greater benefits for all stakeholders
including employees, shareholders, and the DRC".

Jonathan Leslie, Executive Chairman of Nikanor, said: "Individually, Nikanor and
Katanga both present compelling copper and cobalt investment cases; combined,
they transform into an African champion with phenomenal resources and potential.
  This merger is precisely the type of transaction we envisaged when we listed
the company more than year ago, creating a premier publicly traded copper and
cobalt company and generating significant operating and financial synergies. The
combined company will create value for shareholders and other stakeholders alike
and be even better placed to help play a positive role in the development of the
Katanga Province and as a long-term partner to Gecamines and ultimately to the
DRC".

Martin Kabwelulu, Minister of Mines of the DRC, said: "The DRC government would
like to highlight its support for the merger of Katanga and Nikanor. This
transaction highlights the quality of Katanga and Nikanor's deposits and
provides a natural platform between these two projects for the development of
these assets into a major copper and cobalt producer. The combination of
operational synergies between these two companies will result in increased
financial benefits for the DRC state and shareholders. The DRC has 10 per cent.
of the world's copper reserves and less than 1 per cent. of its production. This
transaction is a significant milestone in the transformation of the DRC's mining
sector towards production. The DRC government welcomes the merger as proof of
the confidence of the business community in the future of the DRC mining sector
".

Merger terms

The Merger will be effected by way of the Offer and Cash Return to Nikanor
Shareholders. Under the terms of the Merger Nikanor Shareholders will be
entitled to receive for each Nikanor Share:

          0.613 New Katanga Shares, and

          US$2.16 in cash by way of the Cash Return.

Following the Merger, Nikanor Shareholders will hold 60 per cent. and Katanga
Shareholders 40 per cent. of the Merged Company, calculated on a fully diluted
basis, excluding the recently announced convertible loan from Glencore Finance.
Based on the closing share prices of Katanga (on the TSX) and Nikanor (on AIM)
on 5 November 2007, the Merged Company would have a combined market
capitalisation of US$3.3 billion after the proposed Cash Return, calculated on
the fully diluted number of shares for both companies. The cash element of the
Merger will be paid by way of the Cash Return of US$452 million from Nikanor's
existing cash resources.

Katanga and Nikanor have entered into an Implementation Agreement in relation to
the Merger, which contains provisions regarding the implementation of the Merger
and certain assurances and confirmations between the parties.

Dealing disclosure requirements

The Nikanor Board has determined that Rule 8 disclosures should not be required
in connection with the Merger





                                                                 6 November 2007

                   RECOMMENDED MERGER OF KATANGA AND NIKANOR



Introduction

The Boards of Katanga and Nikanor are pleased to announce that they have agreed
the terms of a recommended Merger of Katanga and Nikanor to be implemented by
way of an offer by Katanga for the entire issued and to be issued share capital
of Nikanor and a Cash Return.  Further terms and conditions relating to the
Offer are contained in Appendix I of this Announcement and will be set out in
full in the Offer Document. Appendix II of this Announcement contains
information on sources and bases used in this summary and the following
Announcement. Terms used in this Announcement have the meaning given to them in
Appendix IV of this Announcement.

Significant potential synergies have been identified, including capital and
operating savings, operating efficiencies and increased production. The Merged
Company's objective will be to use a phased approach to the construction and
development of  facilities with a combined output potential of 400,000 tonnes of
copper cathode and 40,000 tonnes of cobalt (as metal or salt). The DRC will
benefit from the creation of a strong regional champion with enhanced output and
higher royalties and tax payments. The coordination of the Merged Company's
infrastructure spend and corporate social responsibility activities will also be
more effective in producing positive change for the communities surrounding the
operations.

The Merger will bring together the adjacent properties owned by Katanga and
Nikanor and create a Merged Company with the potential by 2011 to become
Africa's largest copper producer and the world's largest cobalt producer.

Officials in the DRC have been kept apprised of the potential Merger and have
expressed their support.

The Merged Company, which will retain the name Katanga Mining Limited, will make
an application to obtain a primary listing on the Main Market of the London
Stock Exchange within 5 months of the Effective Date.  The Merged Company will
therefore have primary listings on the TSX and the Main Market of the London
Stock Exchange.



Terms of the Merger

Under the terms of the Merger, Nikanor Shareholders will be entitled to receive
for each issued Nikanor Share:



0.613 Katanga Shares; and



US$2.16 in cash by way of the Cash Return.



A total of up to 128.1 million New Katanga Shares will be issued upon completion
of the Offer. Immediately following completion of the Offer, Nikanor's current
shareholders will own 60 per cent. and Katanga Shareholders will own
approximately 40 per cent. of the Merged Company calculated on a fully diluted
basis, excluding the recently announced convertible loan from Glencore Finance.
The cash entitlement of the Offer will be paid by way of a Cash Return of US$452
million, based on the fully diluted share capital of Nikanor, from Nikanor's
existing cash resources.  Nikanor Shareholders may elect to receive their
proportion of the Cash Return in pounds sterling, at the exchange rate
prevailing at the date of payment.



It is intended that until the Effective Date, Nikanor will maintain its listing
on AIM, following which a de-listing would take effect no earlier than 20
business days after the Effective Date.



The Katanga Board and the Nikanor Board have unanimously approved the Merger and
are recommending it to their shareholders.



In addition to the receipt of sufficient acceptances under the Offer from
Nikanor Shareholders, the Offer will be subject, amongst other things, to the
approval of the transaction by Katanga Shareholders, the approval by Nikanor
Shareholders of the re-registration of Nikanor under the Companies Act so as to
facilitate certain steps in relation to the Cash Return and regulatory and other
approvals. The Merger is expected to be completed by the end of the first
quarter of 2008.



Katanga has received irrevocable undertakings to support the Merger and accept
the Offer from Glencore Finance, RP Capital Entities with interests in Nikanor
Shares, Oakey Invest Holdings Inc. and Pitchley Properties Limited representing
78.4 per cent. of Nikanor Shares to support the Offer, subject to certain
exceptions in relation to financing arrangements.



Nikanor has received irrevocable undertakings from Arthur Ditto, Tain Holdings
Limited, George Forrest, RP Capital Entities with interests in Katanga Shares
representing 48.1 per cent. of Katanga Shares to support the Merger and not to
accept any competing offer.  In addition, Nikanor has received a similar
irrevocable undertaking from Glencore Finance with respect to the Katanga Shares
issuable upon conversion of the US$150 million convertible loan from Glencore
Finance which was completed on 5 November 2007.  In addition, Arthur Ditto and
Tain Holdings Limited have undertaken to vote in favour of the Merger at the
Katanga extraordinary general meeting in aggregate in respect of 6,843,000
Katanga Shares, representing 8.7 per cent. of the Katanga Shares in issue.



Further details of these irrevocable undertakings are set out in Appendix III to
this Announcement.



Background and Reasons for the Merger

*      The Merger reunites two adjacent assets that were previously part of the
same mine complex. By integrating the two projects, mining plans and capital
expenditure programmes can be optimized and production and operating
efficiencies achieved.



*      Financial and operational synergies are anticipated over the life of the
project from pooling expertise, logistics, mining fleets and processing
facilities. Benefits include reduced capital expenditure requirements due to
shared infrastructure, higher copper and cobalt recoveries, production of a
higher grade copper cathode, increased cobalt production, reduced acid costs
resulting from a balance of oxide and sulphide ores and other cost savings.



*      The Merged Company will have a significantly enhanced profile and the
ability to compete on a global scale. Based on the closing share prices of
Katanga (on the TSX) of C$11.75 and Nikanor (on AIM) of #5.885 on 5 November
2007, the Merged Company, would have a combined market capitalisation of US$3.3
billion after the proposed Cash Return calculated on the fully diluted basis
number of shares after the proposed Cash Return for both companies.

*      The Merged Company will be well-funded, with a pro forma cash balance of
approximately US$745 million as at 30 September 2007, after taking account of
the Cash Return.

*      The Merged Company will follow Katanga and Nikanor's existing strategies
of financing their projects through a mixture of debt and equity. The level of
additional financing required will be determined as part of a combined business
plan but it is expected that production from Katanga and a phased approach to
capital expenditure will result in a lower and delayed requirement for
additional financing than for Nikanor standalone.



*      Management intends to use the phased expansion approach currently being
used by Katanga to bring its Kamoto complex into production on schedule and on
budget. This phased expansion is likely to delay achieving maximum capacity
relative to the combined standalone business plans but will allow a greater
portion of capital expenditure to be funded from internally produced cash flows
and reduced implementation risk.



*      The existing program to rehabilitate the Kamoto joint venture to achieve
150,000 tonnes of refined copper and 8,000 tonnes of refined cobalt a year will
be continued more aggressively, while a mine plan for the combined assets is
being detailed and a new feasibility study completed.



Combined Reserves and Resources

Katanga's reserves and resources are reported to Canadian National Instrument
43-101 ("NI 43-101") requirements. Proven and probable reserves comprise 93
million tonnes of ore at 3.53% copper and 0.37% cobalt. Measured and indicated
resources (excluding reserves) comprise 69 million tonnes of ore at 3.47% copper
and 0.39% cobalt. Total contained copper excluding inferred resources is 5.7

Nikanor Irrevocable Undertakings

Irrevocable undertakings to accept the Offer, subject to certain exceptions in
relation to financing arrangements, have been received from certain major
Nikanor Shareholders, being Glencore Finance, RP Capital Entities with interests
in Nikanor Shares, Oakey Invest Holdings Inc. and Pitchley Properties Limited in
respect of in total 162,015,413 Nikanor Shares representing in aggregate
approximately 78.4 per cent. of Nikanor's issued share capital.  These
irrevocable undertakings continue to be binding in the event of a higher offer
being made by a third party for Nikanor but cease to be binding if:

  * there occurs a material adverse event in relation to Katanga which shall
    only be deemed to have occurred if such event causes an interruption in
    substantially all of production at any of Katanga's mines and such
    interruption is reasonably likely to continue for a period of more than 45
    days or a Katanga Negative Concession Review Event occurs;
  * the Offer is withdrawn by Katanga unless a new revised Offer on equivalent
    or superior terms is announced by Katanga or it is announced that it cannot
    become unconditional; or
  * the Offer or the new revised or replacement Offer has not become
    unconditional by 15 March 2008.



Katanga Irrevocable Undertakings

Irrevocable undertakings to support the Offer and not to accept any competing
proposal, subject to certain exceptions in relation to financing arrangements,
have been received from certain major shareholders and members of the Katanga
Group, being Arthur Ditto, Tain Holdings Limited, George Forrest, RP Capital
Entities with interests in Katanga Shares in respect of in total 37,918,000
Katanga Shares representing in aggregate approximately 48.1 per cent of
Katanga's entire issued share capital. In addition, Nikanor has received a
similar irrevocable undertaking from Glencore Finance with respect to the
Katanga Shares issuable upon conversion of the US$150 million convertible loan
from Glencore Finance which was completed on 5 November 2007  These irrevocable
undertakings cease to be binding if:

  * there occurs a material adverse event in relation to Nikanor which shall
    only be deemed to have occurred if such event causes an interruption in
    substantially all of production at any of Nikanor's mines and such

    days or a Nikanor Negative Concession Review Event occurs;
  * the Offer is withdrawn by Katanga in accordance with the terms of the
    Implementation Agreement unless a new revised Offer on equivalent or
    superior terms is announced by Katanga and Nikanor or it is announced that
    it cannot become unconditional; or
  * the Offer or the new revised or replacement Offer has not become
    unconditional by 15 March 2008.

In addition, Arthur Ditto and Tain Holdings Limited have undertaken to vote in
favour of the Merger at the Katanga extraordinary general meeting in aggregate
in respect of 6,843,000 Katanga Shares, representing 8.7 per cent. of Katanga
Shares.

RP Capital Entities, by virtue of the size of their shareholding in both Katanga
and Nikanor, and George and Malta Forrest, by virtue of contractual arrangements
to be entered into between the Merged Company and Forrest group companies as
described below, will not be permitted to vote in favour of all resolutions to
be considered at the extraordinary general meeting of Katanga.  However George
Forrest and RP Capital Entities with interests in Katanga Shares, who together
hold in aggregate 31,075,000 Katanga Shares, representing approximately 39.4 per
cent. of Katanga's existing issued share capital have agreed not to support any
competing proposals.

Board of Directors

The proposed board of the Merged Company is to be made up of 10 directors as
follows:

Con Fauconnier          Independent Non Executive Director       (Chairman)

Arthur Ditto                  President and Chief Executive Officer

Terry Robinson            Independent Non Executive Director

Robert Wardell            Independent Non Executive Director

George Forrest           Non Executive Director        (George Forrest nominee)

Malta Forrest               Non Executive Director        (George Forrest
nominee)

Raphael Berber           Non Executive Director        (Cosaf Limited / Pitchley
Properties Limited nominee)

Stephen Oke               Non Executive Director        (Oakey Invest Holdings
Inc. nominee)

Aristotelis Mistakidis  Non Executive Director        (Glencore Finance nominee)

It is proposed that an additional Independent Non Executive Director will be
identified and announced (upon approval from the Boards of both Katanga and
Nikanor) prior to the posting of the Offer Document.  It is proposed that
Stephen Jones, the current Chief Financial Officer of Katanga will become the
Chief Financial Officer of the Merged Company and that Peter Sydney Smith, as a
member of the Integration Committee, will have responsibility for the London
listing.

Relationships with Major Shareholders

Nikanor and its major shareholders currently have in place relationship
agreements under which the major shareholders have the rights to appoint certain
of the directors to the Nikanor Board.  As part of the terms of the approval of
the Offer by certain of the major shareholders of both companies of the Offer,
it has been agreed that the major shareholders will have certain appointment and
nomination rights in respect of directors following the Offer becoming
unconditional in all respects.

In particular, it is proposed that George Forrest shall have the right to
appoint 2 non-executive directors; Glencore Finance one non-executive director;
Cosaf Limited   and Pitchley Properties Limited (taken together) one
non-executive director and Oakey Invest Holdings Inc. one non-executive
director.

After three years from the Effective Date, Art Ditto shall cease to be the
President and Chief Executive Officer unless re-appointed by Glencore. In
addition in the event that Arthur Ditto ceases to be the President and Chief
Executive Officer of the Merged Company, Glencore Finance shall have the right
to nominate (but not remove) the Chief Executive Officer and in the event that
Con Fauconnier ceases to be the Chairman, George Forrest has the right to
nominate (but not remove) the Chairman. Such nominations are subject to
confirmation by the nomination committee of the Board. George Forrest will also
be given the right to appoint the Non Executive Chairman of DCP and KCC. It is
intended that Simon Tuma-Waku will be the Vice Chairman of these entities.

None of the rights of the major shareholders set out above shall prejudice the
Merged Company's shareholders right to remove any of the major shareholders'
nominees in general meeting.  Any director appointed to the board by the board
of the Merged Company will automatically come up for re-election at the
subsequent annual general meeting of the Merged Company.

The rights of the major shareholders as set out above to nominate and/or appoint
director(s) is subject to them and their associates holding certain minimum
interests in the Merged Company, being 5 per cent. in the case of each of George
Forrest and Glencore Finance and 10 per cent. in respect of each of RP Capital
Entities and Pitchley Properties Limited (taken together) and Oakey Invest
Holdings Inc.

It is intended that Relationship Agreements will be entered into between the
Merged Company and these shareholders to take effect on the Effective Date.
With effect from the Effective Date the existing relationship agreements between
Nikanor and its major shareholders will cease to have effect.

Glencore Finance, Ruwenzori Limited, Karisimbi Limited (which does not currently
hold any Nikanor Shares) and Cosaf Limited have entered into a co-operation and
voting agreement in relation to Nikanor. The agreement is intended, amongst
other things, to ensure that the parties exercise their respective rights as
shareholders in Nikanor in a co-ordinated manner. The agreement also includes
specific obligations (i) on each party to notify the other parties when it
purchases further Nikanor Shares; and (ii) on the parties (if required by
Glencore Finance) to vote the Nikanor Shares which they respectively hold (a) in
favour of the appointment of Glencore Finance's appointee as either the chief
financial officer and executive chairman or as the chief financial officer and
chief executive officer (as the case may be) of Nikanor (or against the removal
of such person from such office) and (b) in favour of the execution by Nikanor
of certain offtake agreements with Glencore. The agreement also includes
restrictions on the transfer of the Nikanor Shares which are held by the
respective parties and certain pre-emption rights in relation thereto. It is
intended that as from the Effective Date, this agreement will terminate and be
replaced by an agreement in relation to Katanga which will contain essentially
the same terms and conditions as applied with respect to Nikanor and otherwise
making it consistent with agreements as they apply to Glencore Finance as
described in this section and under "Transactions with Major Shareholders"
below. The agreement is governed by English law.



Transactions with Major Shareholders

In connection with the approval of the Offer the Merged Company has agreed to
enter into the arrangements with each of Glencore and George Forrest as set out
immediately below.

Glencore

Katanga and Nikanor have agreed that the Merged Company shall appoint Glencore
as the exclusive offtaker for the Merged Company and its subsidiaries from time
to time pursuant to which it will buy and take delivery of 100 per cent. of the
quantity of copper and cobalt produced by the mines currently owned and
subsequently acquired by Katanga, save for any existing offtake agreements of
the Katanga Group and existing offtake agreements in place at the time of any
newly acquired mines.  The terms on which Glencore shall be appointed shall be
on the same terms, including the same commercial terms, as the offtake entered
into on 5 November 2007 between Katanga and Glencore save that it shall be
extended for the life of all Katanga's mines.  However, in respect of Nikanor,
the existing offtake arrangements between Nikanor and Glencore shall continue
post the Effective Date. Following the Effective Date, Katanga will work with
Glencore on the terms of a unified contract for the offtake from the Merged
Company's operations.

George Forrest

KOL and Entreprise General Malta Forrest have entered into the T17 Open Pit
Mining Agreement and the Dima LOI (a letter from KOL to Entreprise General Malta
Forrest confirming KOL's intention to enter into a commercial contract with
Entreprise General Malta Forrest for the exploitation of open pits of the mining
complex "DIMA" on the basis of the T17 Open Pit Mining Agreement and the usual
standards for such type of contract) and these agreements shall continue
following the Effective Date.  Notwithstanding the Dima LOI, the final pricing
for the Dima LOI is to be agreed with the management of the Merged Company and
approved by the board of the Merged Company.

In addition George Forrest will be granted the right to bid for any new contract
mining or construction contract for the Merged Company's KOV open cut
operations.  If there is more than one bidder, then if the proposals are
equivalent then George Forrest's proposal will be preferred.  In the event that
the sequence of mining is changed and KOV is to be mined ahead of the DIMA pits,
then the Dima LOI will be transferred across to KOV and, notwithstanding the
Dima LOI, the final prices and terms will be agreed between George Forrest and
the management of the Merged Company and approved by the board of the Merged
Company.

It is proposed that George Forrest and the management of the Merged Company will
agree upon the price and terms on which the existing Nikanor and/or DCP on site,
or ordered, equipment will be sold across to, and paid for by, George Forrest to
enable him to perform under his contracts with the Merged Company.

At any board meeting of the Merged Company to vote on these matters, neither of
the Directors appointed by George Forest shall vote on the proposed resolution.

KOL Call Option

In order to give the Merged Company the opportunity to acquire KOL, an entity
owned by George Forrest and Tain Holdings Limited (an entity connected with Art
Ditto) which is the operator of KCC's assets pursuant to the KOL Operating
Agreement, George Forrest and Tain Holdings Limited have entered into a call
option pursuant to which the Merged Company has an option to acquire KOL free
from all encumbrances.  The purchase price payable if the option is exercised
will be determined by an independent investment bank agreed between the parties
as the fair market value to the KOL shareholders, as at the date of the
valuation, based on the Katanga stand alone model as at the date of this
Announcement.

The call option shall be exercisable once the purchase price is determined and
has been notified to the parties, subject to the approval of the board of the
Merged Company and to such regulatory and stock exchange approvals as may be
required.  The call option shall terminate if not exercised within 3 months from
the date the purchase price is determined and notified to the parties.

If the call option is exercised by the Merged Company, the consideration may be
paid in cash or in Katanga Shares or a combination thereof at the election of
George Forrest and Tain Holdings Limited. The number of Katanga Shares to be
issued shall be calculated by reference to the volume weighted average price per
Katanga Share on the TSX for the 5 trading days prior to the exercise by Katanga
of the notice.  No consideration will be paid to George Forrest or Tain Holdings
Limited for the grant of the call option.

At any board meeting of the Merged Company to determine whether to exercise the
option, neither Arthur Ditto nor any of the Directors appointed by George
Forrest shall vote on the proposed resolution.

Integration Committee

Katanga will set up an Integration Committee following this Announcement, to
continue until the listing on the London Stock Exchange is achieved, to oversee
the integration of Nikanor and Katanga into the Merged Company. The Integration
Committee shall consist of at least 4 members, being not less than 2 nominees of
Nikanor and not less than 2 nominees of Katanga. The initial members of the
Integration Committee shall be Peter Sydney-Smith, Rick Dye, Al Schoening, and
Jim Gorman. Peter Sydney-Smith shall be responsible for listing and integration
to hold office until the listing is completed.  The Integration Committee will
be constituted within 2 weeks of the date of this Announcement and will meet in
the period prior to and after the Effective Date, but their proposals will only
be implemented following the Effective Date.  Should the Nikanor appointees
resign, they will be replaced by Nikanor employees for the duration of the
committee.



Management and Employees

Katanga and Nikanor attach great importance to retaining the skills and
expertise of their management and employees.  The boards of Katanga and Nikanor
believe that, although the combination of similar functions may lead to some
operating restructuring, the increased size and strength of the Merged Company
will offer attractive career prospects for its employees.



The existing employment rights of employees of both Katanga and Nikanor will be
fully safeguarded.



Recommendation of the Board of Nikanor

The Nikanor Directors, who have been so advised by JPMorgan Cazenove Limited,
consider the terms of the Offer to be fair and reasonable. In providing their
advice to the Nikanor Directors, JPMorgan Cazenove Limited has taken into
account the commercial assessments of the Nikanor Directors. Accordingly, the
Nikanor Directors intend unanimously to recommend that Nikanor Shareholders
accept the Offer, as they intend to do in respect of their own beneficial
holdings, which in aggregate amount to 253,350 Nikanor Shares, representing
approximately 0.1 per cent. of Nikanor's existing issued share capital.



Katanga Shareholder Approval and Recommendation of the Board of Katanga

The Offer is conditional on the approval of Katanga Shareholders at an
extraordinary general meeting of Katanga to be convened. The Katanga Board
intends unanimously to recommend that Katanga Shareholders vote in favour of the
Offer, and Arthur Ditto and Tain Holdings Limited have irrevocably undertaken to
do so in respect of in aggregate 6,843,000 Katanga Shares representing
approximately 8.7 per cent. of the issued share capital of Katanga, and not to
support any competing proposals.



Nikanor Shareholder Resolutions

The Offer is also conditional upon the passing at an extraordinary general
meeting of Nikanor of certain resolutions, each conditional upon the Offer being
unconditional in all other respects, including, in particular resolutions to (i)
re-register Nikanor as a company incorporated under the Companies Act; and (ii)
to adopt new memorandum and articles of association suitable for a company
governed by the Companies Act, each in order to allow the Nikanor Directors to
effect the Cash Return in accordance with section 50 of the Companies Act.



Conditions to the Offer

The Offer is subject to certain conditions, which are set out in full in
Appendix I of this Announcement.



Inducement Fee

Under the Implementation Agreement:



Nikanor has agreed to pay an inducement fee of #7.62 million (or if lower, 1 per
cent. of the Offer value to Nikanor Shareholders, excluding the Cash Return) to
Katanga, subject to any adjustment for VAT, if:



(a)     a third party announces prior to the Offer lapsing that it may make an
offer for Nikanor, or another third party announces an offer within six months
of the announcement by the first party and one of such offers is declared
unconditional in all respects or completed;

(b)     Nikanor Directors fail to recommend the Offer, or withdraw their
recommendation or otherwise fail to take the steps required to implement the
Offer, save in the event of a Katanga Negative Concession Review Event; or

(c)     Nikanor enters into an agreement which would breach Rule 21(a), (b)(iv)
and (v) of the Code.



Katanga has agreed to pay an inducement fee of US$9.93 million (or if lower, 1
per cent. of the market value of Katanga at the time of this Announcement) to
Nikanor, subject to any adjustment for VAT, if:



(a)     a third party announces prior to the Offer being withdrawn that it may
make an offer for Katanga or another third party announces an offer within six
months of the announcement by the first party, and one of such offers is
declared unconditional in all respects or is completed;

(b)     Katanga withdraws or fails to make the Offer, save in the event of a
Nikanor Negative Concession Review Event occurring or any event giving rise to
an inducement fee payable to Katanga having occurred; or

(c)     Katanga Directors fail to recommend the Offer, or withdraw their
recommendation that shareholders of Katanga approve the transaction or otherwise
fail to take the steps required to implement of the Offer, save in the event of
a Nikanor Negative Concession Review Event. No amount shall be payable if the
condition relating to the requirement for Katanga's shareholder approval is not
satisfied unless Katanga's directors withdraw their recommendation in respect of
such approvals.



Cash Return

The cash payment due to Nikanor Shareholders as part of the Merger is funded by
a distribution paid by Nikanor financed from Nikanor's existing cash resources.
It is intended that Nikanor Shareholders are to approve the re-registration of
Nikanor as a private "Manx" company under the Companies Act, such approval being
conditional on the Offer becoming unconditional and the re-registration effected
in all respects. Upon the Offer becoming unconditional, the Nikanor Board will
make a distribution to the then Nikanor Shareholders which, at the time of the
distribution will include Katanga. To the extent Katanga receives cash pursuant
to the distribution, it will pay the relevant proportion of the Cash Return to
those Nikanor Shareholders whose shares it has acquired pursuant to the Offer.
The Nikanor Shareholders of whose Nikanor Shares Katanga has not acquired as at
the date of the Cash Return will receive their proportional share of the Cash
Return directly from Nikanor. The Cash Return is only required to be paid once
Katanga has received the amount from Nikanor.



Nikanor has agreed pending the Offer becoming unconditional to retain an amount
of cash equal to the Cash Return in a separate account in immediately available
funds.



Nikanor and Katanga will work together in order to determine the most effective
way of giving effect to the Cash Return in a manner to ensure the amount
received by Katanga will be treated as a capital return.  Further details will
be contained in the Offer Document.



Compulsory Acquisition / AIM Cancellation

On receipt of acceptances under the Offer in respect of 90 per cent. or more of
the Nikanor Shares, Katanga intends to apply the provisions of section 160 of
the Companies Act to acquire compulsorily any remaining Nikanor Shares.  The
78.4 per cent. of Nikanor Shares under the irrevocable undertakings to support
the Merger will count towards this 90 per cent. threshold.

In addition, subject to the Offer becoming or being declared unconditional in
all respects, Katanga intends to procure that Nikanor applies to the London
Stock Exchange for the cancellation of the admission to AIM of the Nikanor
Shares. It is anticipated that such cancellation will take effect no earlier
than 20 business days after the Offer becomes or is declared unconditional in
all respects. Katanga also intends to re-register Nikanor as a "Manx" company
under the Companies Act.

Disclosure of Interest in Nikanor Shares

Neither Katanga, nor any Katanga Directors (i) has any interest in or right to
subscribe for any relevant Nikanor securities, nor (ii) has any short positions
in respect of relevant Nikanor securities (whether conditional or absolute and
whether in the money or otherwise), including any short position under a
derivative, any agreement to sell or any delivery obligation or right to require
another person to take delivery, (iii) has borrowed or lent any relevant Nikanor
securities (save for any borrowed shares which have been on-lent or sold), (iv)
has any securities convertible or exchangeable into, or any rights to subscribe
for or purchase, or holds any options to purchase any Nikanor Shares or holds
any derivative referenced to securities of Nikanor which remain outstanding nor
(v) has any arrangements of the kind referred to in Note 6 to Rule 8 of the Code
(including indemnity or option arrangements or agreements or understandings of
whatever nature relating to Nikanor Shares which may be an inducement to deal or
refrain from dealing).

Katanga and Nikanor Share Option Schemes

As a result of the Merger, options and awards under the Nikanor Share Plan 2006
will vest and become exercisable. The Offer will extend to any Nikanor Shares
issued and unconditionally allotted or issued whilst the Offer remains open for
acceptance, including any Nikanor Shares unconditionally allotted or issued upon
exercise of options or vesting of share awards granted under the Nikanor Share
Plan 2006. To the extent that such options are not exercised and share awards do
not vest, and if the Offer becomes or is declared unconditional in all respects,
Katanga will make appropriate proposals to option holders in due course. It is
the intention of the Merged Company to implement new share incentive
arrangements for all management and employees following completion of the
Merger.



Implementation Agreement

Katanga and Nikanor have today entered into an Implementation Agreement which
provides, amongst other things, for the implementation of the Merger and
contains assurances and confirmations between the parties, including provisions
as to the procedure to implement the Offer on and governing the conduct of the
business of Nikanor pending the Effective Date.

The Offer is not subject to the jurisdiction of the Panel. However, Katanga and
Nikanor have agreed in the Implementation Agreement the process for the Offer

existing articles of association, the Offer is a "Permitted Acquisition" (as

acceptances on or before that date.

conduct of the Offer.  In addition, Katanga has given Nikanor certain limited
warranties.

Shareholders who are not resident in and citizens of the United Kingdom may be
affected by the laws of the relevant jurisdiction in which they are located or

applicable legal or regulatory requirements of their jurisdictions. Further
details in relation to UK and overseas shareholders will be contained in the
