Mawson and BATCircle2.0 Co-Funding for the Rajapalot Gold-Cobalt Project, Finland

VANCOUVER, June 21, 2021 - Mawson Gold Ltd. ("Mawson") or (the "Company") (TSX:MAW)(Frankfurt:MXR)(OTC PINK:MWSNF) is pleased to announce co-funding of battery metal geometallurgical support by Business Finland for €397k (CAD$590k) as part of a 50% co-funding of €795k (CAD$1.2M) for the Finland-based Circular Ecosystem of Battery Metals ("BATCircle2.0"). BATCircle2.0 is funded by Business Finland in cooperation with Mawson Oy (Mawson's 100%-owned Finnish subsidiary), the Geological Survey of Finland (GTK) and Aalto University.

Highlights:

• Mawson Oy has been granted €397k (CAD$590k) as part of a 50% co-funding of €795k (CAD$1.2M) for the Finland-based Circular Ecosystem of Battery Metals ("BATCircle2.0") to study cobalt geometallurgy, optimise gold-cobalt separation methods, improve overall cobalt recovery by minimising losses to tailings, investigate on-site production possibilities, reduce environmental impacts of tailings and add to the Finnish circular battery economy;
• Mawson, in conjunction with research partners at GTK, Aalto University and University of Oulu along with Finnish specialist consultants, intends to:
  • Couple the financial return from gold with a requirement to maximise the separation of battery and critical metals including cobalt, nickel, tungsten and copper;
  • Test and demonstrate the viability of enhanced recovery of these by/co-products during mineral processing using green technologies, which will be further developed by GTK and tested on existing tailings;

Mr. Hudson, Chairman and CEO, states, "We are again thankful that Business Finland has chosen to continue to support Mawson in our pursuit to become a significant Finnish (and European) raw material battery-metal supplier from our 100%-owned Rajapalot project, which is already 7^th largest European cobalt resource.

"BATCircle2.0 will build on the work of BATCircle, which provided the most comprehensive metallurgical studies performed at Rajapalot to date. That work demonstrated excellent gold recoveries with a viable method to obtain industrial acceptable recoveries for cobalt to produce a cobalt concentrate that could be further treated by hydrometallurgical methods (leaching, solvent extraction, purification) to produce cobalt sulphate. The battery supply chain, through to the customer, is demanding sustainable and ethically sourced metals and minerals, and the Finnish ability to deliver against these demands, via projects such as Rajapalot, is a unique and competitive advantage. A key to the successful extraction of our battery and critical metals will be a positive net return."

The objectives of Mawson's BATCircle2.0 project are to:

• Optimise enhanced gravity streams for cobalt and gold separation;
• Efficiently separate gold and cobalt/sulphide concentrate streams;
• Add understanding of optimal conditions for flotation of cobaltite;
• Study leaching of non-cobaltite concentrate residues;
• Investigate on-site cobalt metal or salt production;
• Reduce acid production in tailings and carbon capture using Mg-rich waste in tailings;
• Enhance circular battery economy by integrating project results into the economics of recovery of nickel and cobalt from sulphide concentrates.

Many Finnish cobalt-gold polymetallic systems are driven by the economics of gold with the metallurgical focus therefore driven to returns on gold. Losing battery and critical metals to tailings is a poor outcome for Finland and the development of a local circular low-carbon economy. Mawson's Rajapalot gold-cobalt project in Lapland also contains nickel, copper and tungsten, a common Finnish metal association but unusual globally. Drilling for metallurgical sampling will continue,

providing fresh research materials.

Background to BATCircle2.0: The BATCircle2.0 consortium has been granted €10.8 million by Business Finland as part of a total funding budget of €19.3 million. BATCircle2.0 is a key project in Business Finland`s Smart Mobility and Batteries from Finland programs.

The BATCircle2.0 consortium will build on the first phase of BATCircle which was successfully completed in April 2021. The aim of the project consortium is to create a competitive and sustainable European battery industry through collaboration and joint research between companies and research organisations. The BATCircle2.0 consortium led by Aalto University consists of the following universities, research institutions and companies:

• Universities: Aalto University, University of Eastern Finland, LUT University (Lappeenranta Uni of Tech), University of Oulu;
• Research Institutions: Geological Survey of Finland (GTK), VTT Technical Research Centre of Finland;
• Companies: Boliden Harjavalta Oy, Finnish Minerals Group Oy, Fortum Waste Solutions Oy, Metso Outotec Oyj, Norilsk Nickel Harjavalta Oy, Terrafame Oy, Umicore Finland Oy, AkkuSer Oy, BroadBit Batteries Oy, Fennoscandian Resources Ab, FinnCobalt Oy, Keliber Technology Oy, Latitude 66 Cobalt Oy, Mawson Oy, X-Ray Minerals Services Finland Oy
