  FIRST QUANTUM MINERALS RESPONDS TO ADASTRA MINERALS' DIRECTORS' CIRCULAR AND
   ENCOURAGES ADASTRA SHAREHOLDERS TO TENDER TO FIRST QUANTUM'S PREMIUM OFFER

First Quantum Minerals Ltd. ("First Quantum", TSX Symbol "FM", LSE Symbol "FQM")
replied today to the directors' circular filed by Adastra Minerals Inc.
("Adastra") in response to First Quantum's offer to purchase all of the
outstanding shares of Adastra at an exchange ratio of 1 First Quantum common
share for each 17.5 Adastra common shares held. Unless otherwise noted, all
dollar amounts referred to in this press release are in Canadian dollars.

"We believe that our premium offer represents and remains the best opportunity
for Adastra shareholders. Ours is a fair and reasonable offer. Adastra, on the
other hand, has failed to maximize value for shareholders both over the last
several years and since First Quantum's initial approach to Adastra. First
Quantum, by comparison, has achieved significant share price appreciation and
substantial growth since our company was formed in 1996," said Mr. Philip
Pascall, Chairman and CEO of First Quantum. "First Quantum has had extensive
experience in successfully developing, financing and operating major mines and
tailing deposits in the Copperbelt region of Zambia and the Democratic Republic
of Congo ("DRC"). This experience should significantly reduce the execution risk
of Adastra's Kolwezi project and maximize value for Adastra shareholders."

In deciding whether to tender to the First Quantum offer, Adastra shareholders
are encouraged to consider the following:

1.   FIRST QUANTUM HAS DISPLAYED SUPERIOR PROJECT DEVELOPMENT AND OPERATIONAL
     PERFORMANCE AND PRODUCED SUPERIOR RETURNS FOR ITS SHAREHOLDERS THAN HAS
     ADASTRA FOR ITS SHAREHOLDERS

     o    Since 1996 First Quantum has acquired or discovered seven projects,
          has brought three into production, is currently constructing the
          fourth and is preparing to construct a fifth

     o    Adastra has yet to complete a definitive feasibility study on Kolwezi,
          which was acquired in April 1997

     o    Based on the information provided by Adastra in its directors'
          circular, financing for the Kolwezi project is highly conditional and
          it is not apparent that it is at a level sufficient to commence the
          project. To finalize project loan agreements, raise the required
          additional equity and complete final engineering design before the end
          of 2006 is extremely aggressive and may prove unachievable

2.   IN ITS EFFORTS TO FINANCE KOLWEZI, ADASTRA HAS SUBSTANTIALLY DILUTED ITS
     INTEREST IN THE PROJECT WITHOUT CREATING ANY MEANINGFUL VALUE FOR
     SHAREHOLDERS

     o    Over the past two years Adastra's interest in Kolwezi has declined
          from 82.5% to 65% and, if the Mitsubishi transaction closes, will
          further decline to 50.1% while Adastra's shareholders meanwhile have
          not received any cash benefit or meaningful share price appreciation.
          The only material gain in the share price has followed from First
          Quantum's offer announcement

          -    The sale by Adastra of a 17.5% interest in the Kolwezi project to
               the Industrial Development Corporation of South Africa Limited
               ("IDC") and the International Finance Corporation ("IFC") for
               approximately US$12 million essentially represented a recovery of
               costs with zero premium to Adastra shareholders. In light of what


FIRST QUANTUM MINERALS LTD.                                               06-04
- --------------------------------------------------------------------------------

               Adastra are now claiming, this appears to be a significantly
               undervalued sale price. Additionally, Adastra has awarded the IDC
               and IFC, combined, warrants to acquire shares at an exercise
               price of $0.75 per share, which as at February 12, 2003 (the date
               awarded), represented 5% of Adastra's fully diluted shares
               outstanding

          -    The potential sale by Adastra of a 14.9% interest in the Kolwezi
               project to Mitsubishi for US$37.5 million implies a value of
               approximately $190 million for Adastra and is not superior in
               value to First Quantum's offer. In fact, the 15 year exclusive
               off-take contract, to be awarded to Mitsubishi as part of the
               potential sale transaction, is an unusually long exclusive
               off-take which will be of considerable value to Mitsubishi, which
               should be discounted from the consideration offered, thus
               reducing the implied value further. In First Quantum's view this
               transaction taken as a whole represents a dilution in Adastra's
               value and would not be pursued if First Quantum's offer were to
               succeed

3.   FIRST QUANTUM IS OFFERING A SIGNIFICANT PREMIUM WITH UPSIDE POTENTIAL IN
     FIRST QUANTUM SHARES

     o    First Quantum's offer currently values Adastra at $2.21 per Adastra
          share, which represents:

          -    63% premium to the 20 day average price before discussions
               occurred on November 3, 2005;

          -    64% premium to the $1.35 exercise price of options issued to
               management in October 2005 after First Quantum had expressed
               interest in a merger; and

          -    30% premium to the $1.70 equity issue that Adastra completed in
               December 2005.

     o    First Quantum's shares provide a significantly lower risk profile and
          better liquidity for Adastra shareholders. Adastra shareholders stand
          to benefit from First Quantum's strong cash flow and growth

     o    It is likely that First Quantum's board will declare its final
          dividend for 2005 and determine the record date for that dividend
          under its dividend policy after the closing date for First Quantum's
          offer. Adastra shareholders who have tendered their shares prior to or
          on the closing date (and assuming all conditions under First Quantum's
          offer have been satisfied or waived by First Quantum) would be
          entitled to receive, as shareholders of record of First Quantum, their
          pro rata share of the declared dividend

4.   ADASTRA HAS NOT BEEN WILLING TO DISCUSS SHAREHOLDER VALUE MAXIMIZATION WITH
     FIRST QUANTUM

     o    First Quantum has attempted on multiple occasions to negotiate with
          Adastra but these efforts have been rejected in each instance

     o    After First Quantum's first approach in October 2005 Adastra issued a
          1,885,209 options to directors, management and employees at an
          exercise price of $1.35 and 6,000,000 shares from treasury at $1.70

5.   ADASTRA HAS HAD SUFFICIENT TIME TO INVESTIGATE VALUE MAXIMIZATION OPTIONS -
     IT IS TIME TO REMOVE THE SHAREHOLDER RIGHTS PLAN ("SRP") AND LET THE
     SHAREHOLDERS DECIDE

     o    Adastra has owned its interest in the Kolwezi project since April 1997

     o    Adastra has been in discussions with Mitsubishi since April 2005

     o    Adastra and First Quantum had initial discussions in October 2005

     o    Adastra formed a special committee of their board of directors and
          hired NM Rothschild & Sons Limited on December 2, 2005

     o    First Quantum believes that the potential Mitsubishi sale likely
          signals the end to any auction process as potential purchasers (if
          any) are most unlikely to want to be bound by a 15 year exclusive
          off-take contract and the further reduced equity ownership in the
          project

     o    The benefit to shareholders of Adastra's SRP, adopted by the board of
          Adastra in December 2005, is therefore questionable as the Mitsubishi
          arrangement discourages any further value maximization process

By tendering to the First Quantum offer Adastra shareholders will receive shares
in a growing, profitable company with an established dividend policy. They will
benefit from the experience of First Quantum management who have successfully
financed and developed similar projects in this region and in particular the

DRC. They will have an interest in a copper and gold producing company with a
number of operations in 3 different countries rather than a company whose sole
development project is vulnerable to the vagaries of the cobalt market.
