BacTech Announces Agreement With Blackstone Development

  BacTech Mining Corporation ("BacTech" or the "Company") (TSX VENTURE: BM) today announced that it has signed an agreement with Blackstone Development Inc. ("Blackstone") of Cobalt, Ontario, granting the Company access to Blackstone's considerable tailings inventory in the Cobalt camp in Northern Ontario.

Under the terms of the agreement, BacTech will pay $10,000 to Blackstone and issue 1,000,000 common shares in the BacTech reclamation company that will be created following the proposed reorganization (announced January 12, 2010). Also, an additional 100,000 shares will be issued to Blackstone annually for the life of the project, and a 2% NSR will be paid to Blackstone on any metals recovered from the tailings.

It is believed that there are considerable amounts of silver, cobalt, nickel and copper still in the tailings. BacTech will undertake a field program to determine the grades of the various tailings deposits to identify suitable production candidates. The initial workplan will focus on investigating the use of the Company's proprietary technology to stabilize the contained arsenic in the tailings, in addition to recovering the contained metals deemed to be economically recoverable for its own account.

The tailings are a result of extensive silver mining in the Cobalt area from the early 1900s. Given the lack of environmental protocols and technical inefficiencies during the historical mining, considerable amounts of waste rock and tailings were deposited in and around lakes in the area, and that has led to the liberation of heavy metals and arsenic into the local water systems.

The Blackstone tails cover the majority of the Cobalt camp that, at one time, was the most prolific silver mining camp in modern times. The claim package includes more than 50 past-producing mines and their related tailings. Blackstone estimates that as much as 8 to 10 million tonnes of tailings are situated on their land package.

BacTech plans, subject to establishing economic grades of recoverable metals, to build a demonstration plant in the Cobalt area to retreat concentrates recovered from the existing tailings. A proposed site for the plant was also identified on a recent visit to Cobalt.

Testwork was conducted by BacTech on samples collected last summer from the Castle Mine tailings located near Gowganda (see news release June 24, 2009). Gowganda, located approximately 100 km from Cobalt, was thought to contain mineral concentrations similar to those reported for the Cobalt area. However, the Company was unable to duplicate the reported metal content quoted by Gold Bullion Development Corp. at the Castle tailings and, as a result, the Company will focus on the Blackstone tailings going forward, with no further work planned at this time for the Gowganda area tailings.

BACTECH PROFILE

In January the Company announced its intention to effect a divisive reorganization whereby BacTech will transfer all of its interests in mining projects and the rights to its bioleaching technology to a wholly-owned subsidiary. The common shares of the subsidiary will be distributed to the shareholders of BacTech upon completion of the reorganization. BacTech will hold an exclusive and perpetual right to use the bioleaching technology for projects related to environmental remediation of mine tailings. Completion of the proposed reorganization is subject to receipt of all required consents and approvals, including without limitation, court approval, shareholder approval, and TSX Venture Exchange approval. The special meeting of shareholders required to approve the reorganization is scheduled for June 9, 2010.

BacTech owns patented bacterial oxidation technology for the treatment of refractory ores and concentrates to enhance the recovery of gold, silver and base metals. The Company's focus is the acquisition of equity positions in projects amenable to bioleaching.
