(" IDEX " or the " Company ") (TSXV: IDEX; OTCQB: IDXMF) is pleased to announce that it has filed a preliminary short form base shelf prospectus (the “ Preliminary Shelf Prospectus ”) with the securities commissions in each of the provinces and territories of Canada.

The specific terms of any future offering of securities (if any) will be set forth in a shelf prospectus supplement (a “ Prospectus Supplement ”), which will be filed with the applicable Canadian securities regulatory authorities in connection with any such offering. Each Prospectus Supplement will contain specific information concerning, among other matters, the securities to be issued and the use of proceeds from any such issuance.
