| BacTech Granted Two Patents |
| TORONTO, CANADA--(Marketwire - July 30, 2009) - BacTech Mining Corporation ("BacTech" or the "Company")(TSX VENTURE:BM) is pleased to report that two more patents were recently granted to BacTech which further add to the portfolio of advancements in BacTech's technology. One patent has been granted in Chile and the other in Mexico. The patent granted in Chile references a new type of reactor system for bioleaching using low cost materials of fabrication with a novel combination of aeration and mixing to further reduce costs. In one example, the entire bioleaching system can be built quickly as a single, below ground reactor using concrete or, as a plastic lined pit, which can be easily reclaimed at the end of an operation. This is a paradigm shift away from using a conventional series of stainless steel reactors above ground, each equipped with high cost agitators. Dr. Paul Miller, BacTech's Vice President of Technology and Engineering, stated, "We look forward to testing this new low cost reactor system on future projects which would make bioleaching even more cost effective and much simpler to employ. It may provide the quantum leap to take us forward into the next generation of projects in which bioleaching is used as the favoured method for remediation by removing harmful elements from mine wastes, or for treating refractory ores/concentrates in gold and base metal mining". The patent granted in Mexico references an improved method for heap leaching of chalcopyrite. Ross Orr added, "While BacTech is generally recognized as advancing its technology base for treating concentrates, our technical team has also made advancements in heap leaching methods suitable for treating low grade chalcopyrite ores. One of the problems with current heap leaching techniques is that leaching rates are slow, whether or not bacteria are present. Our patented improvements address some of these issues by identifying practical ways to speed up the process and to also make leach rates more predictable." Finally, effective July 31, the Company will terminate its investor relations contract with Pierre Anglos of Cumberland, B.C. CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION Except for statements of historical fact relating to the Company, certain information contained herein constitutes "forward-looking statements". Forward-looking statements are frequently characterized by words such as "plan," "expect," "project," "intend," "believe," "anticipate" and other similar words, or statements that certain events or conditions "may" or "will" occur. Forward-looking statements are based on the opinions and estimates of management at the date the statements are made, and are subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statements. These factors include the inherent risks involved in the exploration and development of mineral properties, the uncertainties involved in interpreting drilling results and other ecological data, fluctuating metal prices, the possibility of project cost overruns or unanticipated costs and expenses, uncertainties relating to the availability and costs of financing needed in the future and other factors described in the section entitled "Risks" in the Company's Management Discussion and Analysis for the Year Ended December 31, 2008. Circumstances or management's estimates or opinions could change. The reader is cautioned not to place undue reliance on forward-looking statements. BACTECH PROFILE 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. In June 2008, the Company signed an agreement to acquire Yamana Gold Inc.'s 33% interest in two refractory gold deposits in Papua New Guinea. In September 2008, BacTech signed an MOU to investigate the use of bioleaching to reprocess arsenic-laden tailings in Cobalt, Ontario. This is the Company's first foray into the cleantech industry. BacTech is continuing to evaluate additional remediation projects. Shares outstanding 83,857,206 |
