      BacTech Provides Update on Prudent Global Debenture
=======================================================================

Toronto, Canada, December 4, 2008 - BacTech Mining Corporation
("BacTech" or the "Company", TSX.V: BM) today announced that it has
been unable to obtain the necessary financing to pay the cash component
of an agreement signed with the Prudent Global Income Fund ("Prudent
Global") of Dallas, Texas, due to the current market conditions and the
short period of time the Company had to raise the funds.

The agreement, announced in a press release November 12, 2008, was to
repurchase a CAD$3 million principal amount unsecured five year term
10% Series I Debenture issued to Prudent Global on March 15, 2004.
Under the agreement, BacTech would have paid CAD$400,000 in cash and
issued 3,500,000 million common shares of BacTech to Prudent Global in
full satisfaction of the outstanding debt obligation.

BacTech will continue to work with Prudent Global to try to negotiate a
reasonable settlement of the outstanding debt obligation prior to the
Debenture maturity date of March 15, 2009.
