ENPAR RECEIVES PATENT APPROVAL FROM THE PEOPLE'S REPUBLIC OF CHINA RELATED TO LEACHING TECHNOLOGY FOR THE RECOVERY OF NICKEL FRO

TORONTO, May 5 /CNW/ -- 
TORONTO, May 5 /CNW/ - ENPAR Technologies Inc. ("ENPAR" or "the
 Company") is pleased to announce that   the Company has been granted a
 patent for its ExtrEL Leaching Technology by the State Intellectual
 Property Office of the People's Republic of China. The patent will
 remain in effect for a term of twenty (20) years from the filing date
 of the application, and management anticipates near-term patent
 approvals from several other jurisdictions including Australia, Canada,
 Russia, South America and United States.


A state-of-the-art, environmentally friendly technology, ExtrEL is being
 developed as a cost effective method for the extraction of nickel from
 mining mill sulphide waste. Designed to recover nickel and other
 valuable by-products at low cost, successful implementation of this
 unique technology is also expected to reduce the impact of acid mine
 drainage (AMD). AMD is identified as one of the most serious
 environmental issues facing the mining industry today.


The Company expects to complete the laboratory development stage by late
 2011. Based on laboratory test results to date, it is anticipated that
 the ExtrEL Leaching Technology has the potential to achieve greater
 than 90% recovery of nickel from sulphide waste materials. Given ready
 access to nickel sulphide tailings deposits similar to those located in
 the Sudbury nickel mining camp, commercial implementation of the ExtrEL
 Technology by mining companies nationally and internationally could
 lead to significant cost savings and profits. ENPAR expects that, in
 addition to the recovery of iron, sulphur and other metals, the system
 will produce relatively low volumes of environmentally stable residual
 material.


Comprised predominantly of iron and sulphur, mill sulphide tailings
 represent an environmental liability to the industry due to the
 environmental impacts of AMD which can last for decades or perhaps
 centuries. The mining industry in Canada reportedly spends more than
 $100 million annually on control measures, with potential, long-term
 liabilities estimated in the billions of dollars.


ENPAR is a "Technology Company" applying its patented and proprietary
 "Electrochemical Technologies" to the treatment of waste water and
 drinking water contaminated by metals or nutrients i.e.,
 nitrate/ammonia associated with the mining, metal processing, chemical,
 agricultural, municipal and waste management sectors. At present, ENPAR
 holds a total of 20 patents and has submitted an additional 18 patent
 applications related to six distinct technologies. The common shares
 trade on Tier ll of the TSX Venture Exchange under the symbol "ENP".
