       FIRST QUANTUM OFFER FOR ADASTRA CURRENTLY VALUED AT $3.28 PER SHARE

First Quantum Minerals Ltd. ("First Quantum", TSX Symbol "FM", LSE Symbol "FQM")
noted today that its offer to acquire all the outstanding shares of Adastra
Minerals Inc. ("Adastra") is valued at $3.26 (assuming the share election) based
on First Quantum's trading price of $48.11 on the TSX as at 11:30 am on March
30, 2006. With First Quantum's dividend, payable May 10, 2006 to shareholders of
record on April 19, 2006, providing a potential for approximately an additional
$0.02 per share to Adastra shareholders, this brings the total value of the
Offer to $3.28 per share.

"Our Offer currently provides a premium of 18% to Adastra's trading price of
$2.77 on the TSX as at 11:30 am on March 30, 2006." said Mr. Philip Pascal,
Chairman and CEO of First Quantum. "This represents significant and immediate
value available to Adastra's shareholders who tender to the Offer. We strongly
urge Adastra shareholders to consider these values and tender to our Offer which
expires tomorrow, March 31, 2006, at 5:00 pm Toronto time."
