BAC BacTech Environmental Corporation

BacTech Environmental Corporation ("BacTech" or the "Company")
(CNSX:BAC)(WKN:A1H4TY) today announced the results of its bioleach test work on
concentrates from the Snow Lake arsenic/gold residue stockpile that is a
refractory material containing high levels of arsenic (16%).


The Company is pleased to report that the patented BACOX bio-oxidation process
oxidizes over 95% of the sulphides. This eliminates future acid mine drainage
environmental problems associated with the stockpile, that are one of the key
drivers of the project.


In addition, the bio-oxidation process renders 88.6% of gold contained in the
sulphides available for extraction, compared to only 9.4% using conventional
gold extraction without oxidation. A high weight loss of 45.7% was obtained
during oxidation resulting in the gold grade almost doubling to 17.8 g/t from
the original 9.80g/t, but still maintaining the same amount of gold in the plant
feed. This mass reduction reduces considerably the size and cost of equipment
required in final gold extraction processing. The reagent consumptions noted in
the test work for gold extraction were also modest and comparable to those
associated with current bio-oxidation plants used in the gold mining industry.


The bioleach work is an integral part of the ongoing Economic Study currently
underway with Micon International. The study is expected to be completed in
April. In addition, BacTech has hired Golder Associates Ltd. who is in the
process of completing the Environmental Impact Statement required for an
Environment Act License.


"These are very good numbers considering the difficult nature of the ore.
Virtually eliminating the release of acid is very important from a reclamation
point of view, as is the high recovery of the contained gold. Historically, we
have found that we should be able to obtain higher recoveries in a commercial
operation compared to the laboratory where optimization of parameters is easier
on a continuous basis and the bacteria used in the process adapt over time to
the type of feedstock", said Ross Orr, President and CEO of BacTech. "This
result clearly demonstrates the effectiveness of BacTech Technology for these
types of environmental remediation"

was conducted by Inspectorate Exploration and Mining Services.


BacTech profile

BacTech Environmental holds the exclusive, royalty-free rights to use the
patented BACOX bioleaching technology for the reclamation of tailings and mining
waste materials. On December 13, 2011, BacTech signed a contract with the Mines
Branch of the Manitoba Department of Innovation, Energy and Mines, to remediate
an arsenopyrite gold stockpile situated at the Snow Lake Mine in Snow Lake,
Manitoba. This is the Company's first project since the Plan of Arrangement was
completed on December 2, 2010.
