Micromem Subsidiary and Norwegian EM Technology Partner

June 24, 2009

Accelerate development of exploration sensor technology; company provides update on previously announced partnership and shifts to Phase Two of its survey tool.

TORONTO & NEW YORK--(BUSINESS WIRE)--Micromem Technologies Inc., (OTCBB: MMTIF, CNSX: MRM) through its wholly owned subsidiary Micromem Applied Sensor Technologies, Inc. (MASTInc), announced that as a result of excellent progress during Phase One, Norwegian EM Technology (NEMT) has requested MASTInc to accelerate the schedule for the availability of its Phase Two survey tool. This tool, based on NEMT's unique survey technology, will enhance the capabilities of its sister company, Excel Expro Norge AS (EEN), for exploration activities in the North Sea and other international oil and gas regions. EEN is a young hydrocarbon exploration company, which was offered a share in exploration rights to a Norwegian offshore license area of approximately 1,000 square km.

MASTInc's client, NEMT, is developing a unique electromagnetic hydrocarbon and mineral exploration survey system for both offshore and onshore oil and mineral exploration. Its patent-pending system is being developed initially for use in a light aircraft, with expectations that this system can perform more efficient, cost-effective, fish and environmentally friendly basin-wide surveys than traditional seismic methods.

Marius J. Mes, Dr. Ing, engineering manager for NEMT, states, "We contracted MASTInc for a multi-phase project to help us realize our survey tool. The capabilities and features of MASTInc's successful HCS magnetic sensor make it uniquely suited for our type of application. In addition, their can-do attitude for developing new technology convinced us to work with them. As a specified first step, MASTInc developed, built and delivered a proof-of-concept Phase One experimental survey system around MASTInc's HCS sensor on time and within budget."

The Phase One receiver, which incorporates Micromem's patented magnetic sensor, was field-tested by NEMT for its ability to perform as a survey receiver for very low power signals within a strong background noise environment. As a result of NEMT feedback and experience gained from the initial Phase One field testing, the test results were used to fine-tune requirements for Phase Two of the survey system development and help detail the design specifications of the Phase Two prototype survey receiver. The Phase Two development aims to provide enhanced performance, capabilities and improved noise suppression/compensation.

The low signal power level requires extremely high gain amplification with as little embodiment circuitry noise addition as possible. Significant electrical noise will also be generated in the environment of use (i.e., an aircraft in this case) that must be suppressed and compensated for as well as possible. MASTInc and NEMT have started working on a Phase Two product development plan that will deliver the required functionality. The Phase Two product will be available for ruggedized field-testing within five to six months.

Steven Van Fleet, president of MASTInc, adds, "MASTInc recently contracted for third party certified sensitivity testing of their magnetic sensor. At 25 KHz and higher sampling rates, the sensitivity was approaching the sensitivity of a cesium vapor magnetometer. The sensor is the smallest in the world with a packaged footprint of less than 200 microns square with an active area of less than 5 microns. NEMT was a client of opportunity for us because of its unusual instrument sensitivity needs and signal processing challenges."

The magnetic sensor, designed in a proprietary and patented gallium arsenide compound, is ideally suited for arraying into complex sensing structures. MASTInc has ongoing sensor optimization that includes patented concentrator designs on a wafer and external circuitry innovations. This is to further improve the signal-to-noise ratio, moving the Hall sensor technology into new sensitivity areas never before achieved by similar sensing technologies.

Dr. Mes concludes, "MASTInc's proven capability of applying its magnetic sensors in enormous arrays is unique and one-of-a-kind. This will provide the hydrocarbon and mineral exploration industry with new tools for their work in the near future, which is expected to represent a huge market potential for MASTInc."
