Macarthur Minerals $10M IPO Spinout of Infinity Mining Limited Closes Oversubscribed

VANCOUVER, Nov. 24, 2021 - Macarthur Minerals Ltd. (ASX: MIO) (TSX-V: MMS) (OTCQB: MMSDF) (the Company or Macarthur) is pleased to announce that the Initial Public Offering (IPO) of its spin-out company, Infinity Mining Ltd. (Infinity) has now closed. The IPO offer opened on 5 November 2021 and closed oversubscribed on 19 November 2021 under its Prospectus dated 28 October 2021.

Macarthur Australia Limited, a subsidiary of Macarthur, as the majority shareholder, will work closely with Infinity to develop these assets to maximize shareholder value. The timing to develop these assets is ideal and further diversifies Macarthur enhancing the opportunity to drive additional value to shareholders.

The current investor interest in Australian Lithium assets was very much a motivator for investors to take up this offering combined with the Company's portfolio of base metal assets.

IPO Lead Manager CPS Capital Group Pty Ltd, Managing Director, Jason Peterson commented:

"CPS is thrilled to have worked with the efficient and hardworking team at Infinity Mining to close out this oversubscribed IPO. The book included multiple cornerstone institutional investors from Australia and Europe who followed up their initial seed investment and was accompanied by strong demand from local Sophisticated and Retail investors. Infinity provides an exciting opportunity due to the blended exposure in key battery metals such as copper/nickel/lithium combined with advanced gold projects which can be accelerated towards near term production. We look forward to the listing and working with Infinity to deliver long term shareholder value."

Joe Phillips, Managing Director of Macarthur Minerals commented:

"Macarthur is pleased to report that the Offer under the Infinity Prospectus has been filled oversubscribed to the maximum A$10m and the company now will seek a 2021 listing date. Infinity Mining has contracted an experienced technical and geological team and will conduct a very active exploration campaign both in the Pilbara and the Central Goldfields over the course of the next few months. Macarthur is pleased to have worked with CPS and their professional corporate team under the guidance of Jason Peterson and I have been personally impressed with the quality of their clients and the reach that this company has in the Australian investment market. Well done to the CPS Perth team."

On behalf of the Board of Directors, Mr Cameron McCall, Chairman
