MGX Minerals Announces Driftwood Creek Magnesium Metal Production Conceptual Engineering Study by Hatch

VANCOUVER, November 10, 2021 - MGX Minerals Inc. ("MGX" or the "Company") (CSE:XMG) (CNSX:XMG.CN) (FKT:1MG) (OTC:MGXMF) announces a review is underway of a Conceptual Engineering Study for the Production of Magnesium by Hatch Engineering (Canada) for Driftwood Creek Magnesium. Due to an increase in the price of magnesium and related special application of magnesium as a solid rocket fuel, MGX has begun a review of the report, commissioned by the Company, and generated by Hatch Engineering in 2018. Findings consist of a required US magnesium market price of $4,000-$6,000 USD per tonne Mg for positive economics to be achieved. Consideration for value added specialized magnesium products such as rocketry were not considered in the study. The 160 page report confirms no technical or economic issues beyond spot price using known technology. Due to the significant increase in magnesium price (reaching >$11,000 USD per tonne in September 2021) and advances in purpose and application for magnesium solid fuel rockets, the project is now under review as a magnesium metal project versus solely as a magnesium oxide project. The report remains confidential for competition related reasons.

Mg/CO2 type rockets

Utilizing powdered magnesium as a solid fuel and carbon dioxide as an oxidant. The calculated specific impulse of powder rocket engines is higher than that of traditional propulsion systems.

Research and Development

MGX has identified a potential research and development partner with an available test site to provide design, production and testing of a large scale Mg/CO2 type rocket potentially utilizing Mg fuel from the Company's Driftwood Creek Magnesium project.

Driftwood Creek Magnesium Deposit

MGX has completed a Preliminary Economic Assessment ("PEA") for the Driftwood Creek magnesium project (Tuun, 2018). The PEA references report title "Driftwood Magnesite Project Mineral Resource Estimate, Brisco, BC", author Allan Reeves, P.Geo, report date September 30, 2016, revised July 21, 2017. The resource highlights are listed as follows:

• - Measured 2.8 million tonnes grading 43.3%plus Indicated 5.2 million tonnes grading 43.3% (M+I) mineral resource totaling 8.028 million tonnes grading 43.3% magnesium oxide (MgO)

  - Inferred mineral resource totaling 846,000 tonnes grading 43.20% MgO

  - Bulk of resource is located less than 100 meters from surface
