BacTech Announces Proposed Financing

   BacTech Mining Corporation ("BacTech" or the "Company") (TSX VENTURE: BM) today announced that it proposes to raise up to $2.0 million by way of a private placement of up to 26,666,667 units priced at $0.075 per unit. Each unit consists of one common share of BacTech and one common share purchase warrant. The warrant entitles the holder to buy an additional common share for a period of 3 years at a price of $0.105 per share.

The Company has received commitments for approximately $1.8 million of the financing. Of the commitments received to date, Yamana Gold Inc. ("Yamana") has confirmed its intention to subscribe for 13,333,333 units or $1 million of the financing. Yamana has conducted studies on BacTech's proprietary bioleach processing technology. It is one of a number of processing technologies being considered for Yamana's majority-owned Jeronimo gold project in Chile. In addition, Baker Steel Resources Trust ("Baker Steel") of London, England, will purchase up to 4,666,666 units, or $500,000.

In connection with the financing, and subject to approval by the TSX Venture Exchange, a finder's fee of 5% cash may be paid to certain arm's length parties. Closing of the financing is conditional upon execution of definitive subscription documents and receipt of all required regulatory approvals.

On June 23, the Company announced that the holders of subscription receipts issued in March 2010 would convert the same into shares and warrants of the parent company, BacTech Mining Corporation, instead of into BacTech Gold Corporation, a subsidiary of BacTech. As a result of the above, Baker Steel will become the largest single shareholder, controlling 18.21% of BacTech. It is anticipated that following the closing of the financing, an individual nominated by Baker Steel will be appointed to the BacTech board of directors.
