Announcement to the Toronto Stock Exchange and Australian Securities Exchange

SUBIACO, May 22, 2023 - The Board of RTG Mining Inc. ("RTG", or the "Company") (TSX:RTG)(ASX:RTG) is pleased to announce that a comprehensive settlement of all outstanding issues with the Villar Family controlled Sage Capital and TVI Resource Development (Phils.) Inc. ("TVIRD") has been reached and a binding Memorandum of Agreement signed. On execution of the final documents, expected in the next month, all litigation that RTG had launched will be withdrawn as part of an agreed restructuring of the Mabilo Project.

The Villar Family is one of the most prominent families in the Philippines and RTG is pleased to partner with them in the development of the Mabilo Project, which is a significant mining project for the country.

The key terms of the agreement for RTG include the following:

• RTG (through SRM Gold Limited) will retain a 40% interest in Mt. Labo Exploration and Development Corporation ("Mt. Labo") with the project also developed by Mt. Labo, in line with Philippine regulatory requirements, with Sage Capital (which is owned by TVIRD) holding the remaining 60%;
• RTG will have a 2% net smelter royalty ("NSR");
• RTG's debt together with interest, currently in the order of US$27M (subject to audit) will be repaid out of the proceeds of Stage 1 of the project, the Direct Shipping Operation subject to customary requirements to address liquidity and ongoing operations of Mt. Labo;
• Funding arrangements for the project as between the major shareholders of Mt. Labo have been successfully renegotiated, (relieving RTG of a sole funding obligation) and replaced with a pro-rata funding obligation, together with a disproportionate funding obligation of Sage Capital, as set out below;
• With debt repayments in full and the NSR, RTG will be entitled to approximately 57% of the proceeds of Stage 1, the Direct Shipping Operation;
• RTG will be entitled to 40% of the operating cashflow of the project, together with the 2% NSR and repayment of its debt, which is currently in the order of US$27M;
• The first US$5M of expenditure for Mt. Labo (or 12 months of expenditure, whichever occurs the earlier), will be funded pro-rata between the two shareholders (ie RTG will provide 40%) and thereafter, Sage Capital/TVIRD will sole fund the next US$5M of expenditure, with all additional funding thereafter to be provided on a pro-rata basis;
• All parties are required to act in the best interests of the project and not compete;
• A shareholders' agreement will be finalised which will provide typical minority interest protection clauses including reserve matters for voting including annual budgets and appointments of key personnel;
• Any disputes will be resolved by the Singapore International Arbitration Centre; and
• On completion of final signed documents, all litigation matters will be withdrawn and settled in full.

With the restructuring of the Mabilo Project now agreed, over the balance of this year, the remaining permitting matters and financing plans will be finalised, a review of the 2016 Feasibility Study will be completed, together with finalising the acquisition of surface rights, following which, a commitment to development will be formalised by the Board of Mt. Labo.

RTG is pleased with the outcome of the discussions and the co-operative and constructive approach adopted by the Villar Family representatives. RTG believes they can be a strong and positive partner to work with to take the Mabilo Project forward, with both a near term development and future exploration activities to expand the project, which will start to unlock the value of the project for all stakeholders, not only the local communities but for the country as a whole.
