Implant Sciences Awarded Contract to Deploy Explosives Trace Detection Units at Nigerian Corporation to Protect Against Terrorist Threats

WILMINGTON, MA--(Marketwire - Nov 2, 2012) - Implant Sciences Corporation ( OTCQB : IMSC ), a high technology supplier of systems and sensors for homeland security and defense markets, today announced it has sold three more Quantum Sniffer™ QS-H150 handheld explosives trace detectors to a corporate customer for critical infrastructure protection in Nigeria.

This marks the fifth sales contract in the African nation in the past six months. This was the second sale made by Implant Sciences' in-country Nigerian distributor, AC Belgrave. Recent sales in Nigeria have included deployment for airline catering and hotels.

"We've experienced a rapid expansion in our sales since the first QS-H150 was sold into the country just months ago. The unfortunate growing threat from terrorist groups has created a need for high security at commercial and governmental buildings. The Quantum Sniffer can play a growing role in this security environment," stated Darryl Jones, Implant Sciences' Vice President of Sales and Marketing.

"In a similar trend to what we have experienced in China, initial sales of our Quantum Sniffers are quickly generating a positive reputation for reliability and accuracy in Africa. Thanks to our dedicated local distributors' superior sales and customer service capabilities, we are able to deliver high-quality, high-performance, made in the U.S.A. equipment to our international customers. We anticipate continued growth in the African continent," added Glenn D. Bolduc, Implant Sciences' President and CEO.
