:: BacTech Engaged to Study Bioleaching for Continental's Viken Deposit in Sweden

BacTech Mining Corporation reports that Continental Precious Minerals Inc. has commissioned the Company to examine the potential use of BacTech's bioleach technology for the treatment of CPM's black oil shale assets in Sweden known as the Viken deposit.

Black shale deposits are polymetallic by nature, with a variable proportion of sulphide components which may lend themselves to treatment using bioleaching to remove the sulphide components and liberate valuable metals. The metal values, including uranium, molybdenum, nickel and vanadium, are generally encapsulated or trapped in organic matter and are present as small-sized particles. A National Instrument 43-101 compliant technical report was recently published by CPM on the Viken deposit outlining an inferred resource estimate of 2.83 billion tonnes.

An investigation on the amenability of ore samples from the Viken deposit to BacTech's bioleaching technology will be conducted in the Microbial Geochemistry Laboratory at the University of Toronto under the guidance of Dr. Chris Kennedy and Dr. Paul Miller, BacTech's Vice President of Technology and Engineering. A laboratory was recently established by Dr. Kennedy at the University, suitable for conducting such investigations. Ross Orr, President & CEO of BacTech commented, "This is a new potential area of application for our technology and, considering the importance of such deposits, it could represent a highly profitable diversification of our business into the treatment of low grade oil shales for metal recovery." The initial investigation is anticipated to take about four months to complete.
