BacTech Provides Corporate Update.

TORONTO -- The Board of Directors of BacTech Mining Corporation ("BacTech")(TSX VENTURE:BM) today announced that it is actively exploring and pursuing alternatives to maximize and preserve shareholder value, including the sale or merger of the Company or a sale of its major asset, its 55% interest in the Tonkin Springs Mine, located on the Cortez Trend in Nevada. BacTech has held discussions with third parties concerning strategic and financing alternatives over the past six months; however, these discussions have not resulted in a transaction to date.

BacTech has been notified by the Nevada Bureau of Land Management ("BLM") that it will be required to increase its current reclamation bond in respect of the Tonkin Springs Mine by USD$1.1 million from USD$1.7 million to USD$2.8 million. As of March 11, 2005, BacTech is non-compliant with respect to the BLM reclamation bond funding obligation. BacTech has 30 days to post the additional reclamation bond. In the event the bond is not posted, the Company's 55% interest in Tonkin Springs will revert to U.S. Gold Corporation, the original owner of the property.

In addition, BacTech has an interest payment due on March 21, 2005 in the amount of $300,000 on its $3 million 10% redeemable debenture. BacTech currently has a working capital deficit of approximately $1,868,000 (including $1,700,000 due in respect of the reclamation bond funding obligation and the interest payment on the redeemable debenture) and cash resources of less than $350,000.

CORPORATE PROFILE

BacTech has developed and patented bioleach technology for the treatment of refractory ores and concentrates over the past 16 years to enhance the recovery of gold, silver and base metals. BacTech has successfully commissioned three bioleach plants for gold and demonstrated its technology in the selective recovery of base metals from complex sulphide concentrates in a joint project with Industrias Penoles de C.V. of Mexico.

BacTech acquired a 55% stake in Tonkin Springs LLC, the owner of the Tonkin Springs gold project in north central Nevada, in July 2003. BacTech has entered into a series of agreements in China and the Philippines that could see the Company participating in certain projects. The Company continues to evaluate additional projects where BacTech's bioleaching technology may be employed.
