Micromem Receives ARTRA Gas Specifications

Toronto, Ontario and New York, New York, July 13, 2023 - Micromem Technologies Inc. (CSE: MRM) (OTCQB: MMTIF) ("Micromem") ("the Company") is pleased to announce it has received the detailed specifications for an ARTRA natural gas unit (the "Unit") which is to be delivered to Romania. The Unit specifications will allow for the Company's first sale of a diagnostic ARTRA unit relating to natural gas wells.  This Unit, which is now being costed, will be built in California by our engineering partner firm, Entanglement Technologies. The Unit will be utilized for testing purposes and to assess the viability for widespread adoption and use in operating gas wells; it is intended to be an integral component of an interconnected smart network for commercial gas wells. This opportunity to expand Micromem's market for the ARTRA unit to the natural gas well market is a logical extension of Micromem's initiatives in the energy sector; it provides the Company the opportunity, going forward, to advance the development of a comprehensive analytics capability for  operating gas and oil wells.

The Company  believes that the  potential  opportunity  for  this  Unit  in Romania  is  considerable; our  estimate is  that  there are  in excess  of  10,000 operating  gas wells in Romania. Micromem expects that it will receive a purchase order for this Unit over the next several weeks. This follows the purchase order for the oil well unit that Micromem previously announced on July 5^th.  Micromem is expecting follow up specifications for additional units to follow with additional purchase orders.
