Micromem Provides General Update

Toronto, Ontario and New York, New York--(Newsfile Corp. - July 19, 2017) - Micromem Technologies Inc. (CSE: MRM) (OTCQB: MMTIF) ("Micromem") ("the Company") provides the following update:

The Company has been made aware of certain information ("Information") which has been distributed by an outside source (s) to an estimated 300 or more individuals including Micromem shareholders. This distribution contains false and misleading statements and may be construed as defamatory. The Company is now assessing whether any insider information has been shared, disclosed or released in the dissemination of the Information.

The Company provides the following additional commentary at this date:

1. It confirms that the financial statements and MD&A disclosures filed on June 28^th, 2017 for the quarter ended April 30, 2017 fairly present the status and the financial position of the Company as of that filing date. All subsequent material events since that date are as reported in our subsequent press releases.

2. In the Information that was circulated, we note a comment that one of our directors is owed $900,000 by the Company, this statement is incorrect. This director was a subcontractor for a period of several years beginning in 2013. The director invoiced in excess of US $3 million for services provided as a subcontractor through 2015 and was fully paid for these services by the Company.

   The President of the Company's wholly owned subsidiary, MAST Inc, who is also a director of the Company, was, throughout this period, the direct supervisor of this subcontractor and approved these charges.

   The President of MAST Inc. ultimately decided to stop utilizing the services of this subcontractor to the Company thereafter. He approved charges totaling approximately $167,000 as the remaining balance owing to this subcontractor and that amount has been recorded in the Company's accounts as owing to this subcontractor since the 2015 fiscal year. The Company has made multiple attempts to resolve this balance owing including a request that the subcontractor return capital assets purchased by the Company that remain in the subcontractor's possession and that a current audit of those charges be conducted by the Company's CFO, directly with the subcontractor .To date, the subcontractor has not responded to these requests by the Company nor has he returned the assets.

3. At this date, all invoices submitted to the Company by subcontractors engaged to work on the Company's projects — generally described in our disclosures as the inter well tracer project and the wear metal detection project - are fully paid by the Company.

   The Company is in current discussions with the end user customers/partners for these projects pertaining to the go-forward development path and timetable for completion of the next phases of work. Our customers and our subcontractors, who are completing this work, have indicated their willingness to work together with the Company going forward.

4. The independent directors of the Company continue to evaluate on an ongoing basis the performance of all of the officers of the Company.
