Mr. Jeffrey Steiner, on behalf of the Board, is pleased to report that Mr. Jack R Cartmel has been appointed as CFO of Altair
effective May 10, 2021.

Jack Cartmel is a Vancouver-based Chartered Professional Accountant with over 15 years of experience in the mining industry. Jack has been involved and assisted numerous public companies implement their strategic business plans. As part of ALTAIR’sn compliance action plan the appointment of a new CFO achieves separation of that role from the CEO pursuant to TSX Venture Exchange regulations, as Mr. Steiner has served as the Interim-CFO in recent months.

The Company has also finalized a non-binding letter of intent (the “Agreement”) with International Millennium Mining Inc. to acquire a 65% interest in the Simon Property located in the state of Nevada. The Agreement provides for staged share payments with 500,000 shares of the Company to be issued upon receipt of regulatory acceptance to the Agreement. To fully earn its interest the Company will have to issue an additional 1.5 million shares over six years. Cash payments of US$2,000 per month, commencing August 2021, will also be required pursuant to the Agreement. The exploration commitment for the first year of the option is US$85,000. To fully earn its interest an additional US$2.115 million of exploration expenditures will be required by the end of the six-year option term.

The Simon Property, located in the Cedar Mountains, approximately 90 km east of Hawthorne, Nevada, is a polymetallic past producer, that was mined intermittently between 1916 and 1968. More recent exploration work, which included 3D IP resistivity surveying, magnetic surveying, mobile metal ion geochemistry sampling, and geological mapping, carried out in 2007 and 2008, has identified six anomalous zones, four of which are prime targets for further exploration, including drilling. These targets include silver/lead/zinc mineralization; gold, with silver and copper mineralization; gold/silver/copper with minor amounts of lead, zinc and antimony; and molybdenum, with anomalous values of copper and antimony. The reader is cautioned that these data cannot be relied upon for investment purposes and that any such data need to be confirmed by a Qualified Person.

The material in this press release has been reviewed and approved by Dr. Stewart A Jackson, PGeo., a Qualified Person under National Instrument 43-101, and independent of the Company.

This is the first property acquisition which ALTAIR has arranged in 2021, and the Company is continuing with its consideration and negotiations on other properties. The Company is evaluating potential precious metal and non-ferrous metal opportunities in North America and Africa, in addition to Kazakhstan and Central Asia.
