Field testing of ENPAR's acid mine drainage (AmdEL) technology is successful

    TORONTO, Oct. 21 /CNW/ - ENPAR Technologies Inc. (TSX-V: ENP) ("ENPAR" or
the "Company") is pleased to announce positive results from field testing of
its patented "ACID MINE DRAINAGE" Electrochemical Cover (AmdEL) Technology.
    The objective of the study was to test the effectiveness of the AmdEL
Technology to provide a sink for oxygen, thereby inhibiting the oxidation of
sulphide mine tailings and limiting the generation of acid mine drainage (AMD)
and associated leaching of metals.
    ENPAR'S AmdEL Technology operates independently of the mineralogy and
associated electrical properties of the underlying waste material (e.g.,
sulphide mine tailings and/or waste rock).
    The independent study was supported by the Mine Waste Technology Program,
which is funded by the U.S. Environmental Protection Agency, (EPA) and jointly
administered by the EPA and the U.S. Department of Energy.
    The field research was conducted by MSE Technology Applications Inc.
(MSE) at its test facility in Butte, Montana. MSE is a diversified research
and engineering company that provides engineering, management, and technical
support services to agencies of the U.S. Government on behalf of other public
and private sector clients.
    The 2-year study utilized low sulphide mine tailings from the local
Golden Sunlight Mine, and was comprised of 4 in-ground test cells (2
electrochemically-enhanced treatment cells and 2 untreated control cells) with
each test cell consisting of a 1.5-metre diameter in-ground hole approximately
3 metres in depth. Acid base accounting was utilized as the indicator of
sulphide oxidation.
    One of the electrochemically-enhanced cells retained 100 percent of its
original sulphide sulphur content in the upper layer of the tailings, whereas
the untreated cells contained less than 1% total sulphide sulphur at the
conclusion of the demonstration.
    Dr. Gene Shelp, President and CEO of ENPAR Technologies stated, "the
extremely positive results of this independent study reaffirm the Company's
assertion that the AmdEL Technology represents a novel non-invasive method of
controlling acid mine drainage. Our goal is to provide the mining industry
with another effective tool to assist in managing the long-term disposal of
and significant environmental risk associated with reactive sulphide waste
    Acid mine drainage and acid rock drainage (ARD) remain the greatest
environmental problems facing the mining industry today. The cost of
remediating AMD/ARD sites in Canada and the USA alone has been estimated at
greater than US $50 billion. Thus, the mining industry is interested in
identifying new technologies that may enhance its competitiveness and reduce
its environmental footprint and financial liability.
    ENPAR'S AmdEL Technology shows significant promise as a complementary
technology for more conventional cover strategies or as a stand-alone system
to mitigate AMD/ARD.
    The success of this independent study will form the basis for the
Company's future commercialization and marketing strategies.
