NEWS RELEASE

Improved Offer Mailed to Adastra Shareholders

Trading: TSX and AIM: AAA

London, UK (April 18, 2006) - Adastra Minerals Inc. (“Adastra”) advises its shareholders that the notice of variation and extension amending First Quantum Minerals Ltd.’s (“First Quantum”) improved offer for Adastra (the “Improved Offer”), as announced on April 11, 2006, together with an amended Adastra Directors’ Circular, was mailed to shareholders today, resulting in the Improved Offer expiring on April 28, 2006.

The Board of Directors of Adastra, after careful consideration and the recommendation of the Special Committee of independent directors of Adastra and with the benefit of advice from its legal and financial advisors, has determined that the Improved Offer is fair to Adastra shareholders and unanimously recommends that shareholders accept the offer.

About the Improved Offer

The Board of Directors of Adastra announced on April 11, 2006 that it had entered into a definitive support agreement with First Quantum in respect of the Improved Offer.

In the Improved Offer, Adastra's shareholders will have the right to elect to receive either: (a) Cdn.$2.92 in cash per Adastra share; or (b) one First Quantum share plus Cdn.$0.265 in cash (in lieu of being entitled to First Quantum’s May 10, 2006 dividend payment for which Adastra shareholders will no longer be eligible) for every 14.76 Adastra common shares tendered, subject to pro ration based upon the maximum amount of cash and First Quantum shares offered. The maximum amount of cash to be paid by First Quantum will be approximately Cdn.$41.0 million, and the maximum number of First Quantum shares to be issued will be approximately 4.9 million, taking into account the conversion of Adastra's outstanding share options and warrants. Assuming full pro ration of these maximum amounts, this would result in approximately Cdn.$0.475 in cash and approximately 0.057 First Quantum shares per Adastra common share.

Based on the April 17, 2006 closing price of First Quantum shares of Cdn.$51.92, the implied value of the Improved Offer is approximately Cdn.$3.44 (assuming full pro ration).

Adastra is an international mining company listed on the Toronto Stock Exchange and on AIM, in London, under the symbol “AAA”. It is currently developing several mineral assets in Central Africa, including the Kolwezi Tailings Project and the possible rehabilitation of the Kipushi zinc mine in the Democratic Republic of Congo.

NEWS RELEASE

Conditional Proposal from Mwana Africa PLC -

Adastra Board reiterates its recommendation to shareholders to accept First Quantum Offer

Trading: TSX and AIM: AAA

London, UK (April 27, 2006) - Adastra Minerals Inc. ("Adastra" or the "Company") announces that it has today received a letter from Mwana Africa PLC ("Mwana") proposing that Mwana acquire Adastra. In the letter, Mwana states:

“Based on current information, we would be prepared, subject to receiving the Board's prior written consent, to propose to make an all cash offer for Adastra at no less than C$3.85 per share (the "Offer"), conditional only on the following:

•

The unanimous recommendation of the board of Adastra;

•

A break fee and support agreement from the board of Adastra;

•

Confirmation that Adastra's Kolwezi project financing package is executable;

•

Understanding of your financial model and the value that lies in the sub-surface rights and the potential to double production at the Kolwezi Tailings Project;

•

Satisfactory confirmatory due diligence.

Mwana intends to fund the consideration through a combination of existing funds and a Convertible Loan Stock ("CULS") structure which would be fully underwritten by JPMorgan Cazenove.

The acquisition of Adastra would require Mwana shareholder approval in general meeting.”

On April 18, 2006 the Board of Directors of Adastra determined that the improved offer (the "First Quantum Offer") from First Quantum Minerals Ltd. was fair to shareholders and unanimously recommended that shareholders accept the offer which expires at 11.59pm (Toronto time) on April 28, 2006.

The Board met today and carefully considered the proposal it received from Mwana. In doing so, the Board noted that although the price per Adastra share indicated in the Mwana letter is higher than the current value of the First Quantum Offer, the Mwana proposal is subject to a number of conditions, including Mwana shareholder approval, due diligence, and a condition relating to Adastra's project financing. In addition, there is no assurance that a formal offer from Mwana would be forthcoming, and that if received, any formal offer from Mwana would not be able to be consummated until at least June 2006 (and would be subject to certain risks of completion until that time), as compared to the First Quantum Offer which expires tomorrow.

Based in part on these considerations, the Board, after receiving advice from its financial and legal advisers, reiterates its recommendation to shareholders to accept the First Quantum Offer.

Adastra is an international mining company listed on the Toronto Stock Exchange and on AIM, in London, under the symbol “AAA”.
