NOTICE OF MEETING AND MEETING ARRANGEMENTS

25 October 2021

Dear Shareholders

Notice of Annual General Meeting - Great Southern Mining Limited (Company)

Notice is hereby given that the Annual General Meeting ( Meeting ) of the Company will be held at Suite 4, 213 Balcatta Road, Balcatta, Western Australia on Thursday, 25 November 2021 at 9:00am (WST) via videoconference.

Given the current COVID-19 circumstances and in the interests of public health and safety of our Shareholders, the Company is not able to allow Shareholders to physically attend the Meeting.

The Meeting will be accessible to all Shareholders via videoconference, which will allow Shareholders to listen to, ask questions and observe the Meeting. Shareholders who wish to participate in the Meeting can do so remotely by emailing the Company Secretary at mark@gsml.com.au and registering their interest. Videoconference details will then be sent out prior to the event.

Shareholders who do not wish to vote using a Proxy Form and who intend to vote on a poll at the Meeting must contact the Company Secretary on the email above by 23 November 2021 to notify the Company of their intentions and to request a personalised poll form.

The Company will send personalised poll forms following the cut-off time for the return of Proxy Forms (as indicated in the Notice of Meeting) to Shareholders who request them prior to this time. Personalised poll forms must be completed and returned to the Company after the poll has been called and prior to the close of polling. During the Meeting, the Chair will notify you how and when you are able to complete and return the personalised poll form.

You may still attend the Meeting via the videoconference facility if you have completed a Proxy Form (but have not notified the Company that you intend to vote using a poll form), but the person you have appointed as proxy will cast your vote on your behalf.

The Company strongly encourages all Shareholders to lodge Proxy Forms prior to the Meeting.

The Notice of Meeting is available on the Company’s website at www.gsml.com.au and should be read in its entirety. If you are in doubt as to how to vote, the Company encourages Shareholders to seek advice from their accountant, solicitor or other professional advisor prior to voting.

If you have any difficulties in obtaining a copy of the Notice of Meeting, please contact Mark Petricevic by email (email address above) or by telephone on (08) 9240 4111.

Authorised for release by the Company Secretary.

Sincerely

Mark Petricevic
