GENERAL MEETING – NOTICE & PROXY FORM

Dear Shareholder,

Redbank Copper Limited ( ASX: RCP ) (“ Redbank ” or “ the Company ”) invites you to attend a General Meeting (“ Meeting ”) of shareholders to be held at the Vibe Hotel, Level 9, 9 Alvan Street, Subiaco, Western Australia on 10 June 2022 commencing at 10.30am WST.

Meeting Summary & Redbank Strategy

The business of the meeting seeks ratification and/or approval for:

• Option issue to Managing Director Hugh Thomas which formed a material part of his employment contract;

• resolutions arising from the recent $4M capital raising (see ASX release dated 11[th] April), to underpin the 2022 exploration season at the Redbank Copper Project in the McArthur Basis, Northern Territory;

• Change of Company name to NT Minerals Limited.

Over the past 12-18 months, the Company has made significant exploration progress with several high priority copper drill targets identified and significant advancements made towards better understanding the structural controls and existing mineralised systems within the broader Redbank Project area.

The Redbank Project has shown itself to be an exciting exploration opportunity, with several of the targets identified to date exhibiting key features of sediment hosted copper deposits. The foundations have been set and the Company is now well positioned to unlock the underlying value of this asset through targeted and systematic exploration.

The $4M capital raising was strongly supported and will provide the Company with funding to capitalise on the extensive technical work completed to date, and the confidence to aggressively pursue the fast-approaching 2022 field season at Redbank.

In addition, the Board also seeks approval to change the name of the Company from ‘Redbank Copper Limited’ to ‘NT Minerals Limited’ which the Board believes better reflects the Company’s strategic direction and signals the commencement of an exciting new chapter in the Company’s development.

Shareholder approval will also be sought for the issue of 7,500,000 Options to Managing Director Hugh Thomas as part of his employment contract. The Board considered it necessary, appropriate and equitable to have the Options as additional non-cash remuneration to secure Hugh’s services and to incentivise him to pursue the growth and success of your Company.

Since joining the Board in February, Hugh has made a significant contribution towards improving the Company’s capital position and strategic planning and his skills and leadership will be vitally important as the Company embarks on this next phase of growth.
