SUMMARY OF OPERATIONS

PHILIPPINES INTERESTS – THE MABILO COPPER AND GOLD PROJECT

Development Strategy: Working towards near-term DSO start-up

RTG’s primary focus continues to be on advancing the Mabilo Project to start-up.

Importantly, the Mabilo Project has a significant advantage, with the first phase of the Project being a DSO operation, with limited capital expenditure requirements, for which, Mt. Labo has executed the binding finance and offtake term sheet to fund 100% of the planned capital expenditure for Stage 1 of the Project, with the primary source of ore being the 0.104Mt of supergene chalcocite material at an average reserve grade of 20.7% Cu.

The relationship with joint venture partner, TVIRD continues to build momentum, with a strong collaboration between the two teams.

As reported on 6 March 2025, Mt. Labo has entered into a strategic partnership with Glencore to finance 100% of the planned capital expenditure for Stage 1 of Mabilo. The secured financing facility provides for a total of up to US$30M (in three-tranches), on attractive terms, for the development of Stage 1 of the Mabilo Project as well as working capital requirements:

• Tranche A, for US$3.5M, provides early funding flexibility to complete Stage 1 project land acquisition, with limited conditions precedent;

• Tranche B provides US$21.5M for the balance of development of Stage 1 of the Project together with any working capital needs; and

• Tranche C provides US$5.0M for any additional working capital purposes subject to consent of both parties

With key financing milestones achieved during the previous quarter, the key remaining tasks to address and complete prior to a commitment to development are to finalise the land acquisition program for surface rights and permitting for coconut tree cutting.

RTG conducts fortnightly meetings with TVIRD, and good progress continues to be made towards the completion of start-up plans.

Mabilo Project: Background Summary

Mt. Labo has secured the Mining Permit, the successful Final Award in the SIAC matter, won the Setting Aside action of Galeo Equipment Corporation (“Galeo”) in Singapore and has executed the binding debt finance and offtake term sheet to fund 100% of the planned capital development budget for start-up of Stage 1 of the Mabilo Project.

• The Villar Family, our partner in the Mabilo Project, 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.

• RTG will have 40% of Mt. Labo; a 2% net smelter royalty; RTG’s loans to Mt. Labo, currently in the order of US$27 million (A$42.8 million), will be repaid early out of the proceeds of Stage 1, the DSO, subject to customary requirements to address liquidity and ongoing operations of Mt. Labo and repayment of external debt to finance Stage 1 of the project.

• Mt. Labo received written confirmation in May 2020 that the MGB has approved the consolidation of the current Mineral Production Sharing Agreement No. MLC-MRD-459 for the Nalesbitan Project to include the Mabilo Project, having already secured an approved Declared Mine Feasibility Study and Environmental Clearance Certificate for the Project.

Exploration and Development Activities

Resource Extensions

No exploration activities were undertaken during the June quarter.

The next round of exploration, expected this year, will likely focus primarily on sterilization drilling and extensions to the oxide reserve and resource.

An important follow-up drilling program will be undertaken in due course on the porphyry target located under volcanic cover between the South Mineralised Zone and the East Mineralised Zone and extension drilling of the skarn system along strike, with additional infill drilling in the inferred material.

The porphyry target is well supported by mineralized porphyry veins (b-veins) that have been intercepted

in the resource drilling, combined with increasing intensity of calc-silicate alteration and the trending of metallogenic vectors. Mabilo Mineral Resource

KYRGYZ REPUBLIC INTERESTS – THE CHANACH PROJECT

RTG holds a 90% interest in the Chanach Project.

Highlights of the Chanach Project include:

• Existing high-grade JORC compliant Inferred Mineral Resource of 2.95 Mt @ 5.11 g/t Au for 484,000 ounces of Au and 17.23 Mt @ 0.37% Cu for 64,000t of Cu[1] (141.1 Mlbs Cu) from only limited drilling to date ;

• Favourable acquisition cost of US$3.65 / ounce of Gold and US$0.0063 / pound of Copper;

• Experienced technical expert, advising RTG, believes the exploration potential at the Chanach Project is excellent – new drilling program undertaken this quarter; and

• A three-year renewal of the Exploration Licence, has been finalised and granted. The Exploration Licence was issued by the State Committee of Industry, Energy and Subsoil Use of the Kyrgyz Republic.

The Chanach Project is located in the prolific southern Tien Shan metallogenic belt, which runs more than 1,500 km from Uzbekistan through to China and hosts one of the world’s largest open pit gold mines, Murantau (175 Moz[2] ) with production believed to be in the order of 2 million ounces per annum[2] .

The Chanach Project has extensive outcropping mineralised geology with high-grade gold veins from surface and significant gold and copper Inferred Mineral Resources. Trenching and sampling was completed in previous years, with the 3DIP and 2DIP programs undertaken during the last field season. The Chanach Project area is highly prospective for world class epithermal gold, porphyry copper-gold and polymetallic skarn deposits already identified.

To date the limited exploration activities have defined an Inferred Mineral Resource of 2.95 Mt @ 5.11 g/t Au for 484,000 ounces of Au and 17.23 Mt @ 0.37% Cu for 64,000t of Cu .

Exploration and Development Activities

2025 Drilling Program

A 5,000m drilling program has commenced to provide further structural information and investigate targets from the 2DIP and 3DIP interpretation from last field season’s work that showed several anomalies that warranted drill testing. These included the “textbook type” porphyry signatures that had a very strong chargeable anomaly (sulphides) and a resistive centre with a demagnetised zone in the middle. Three (3) holes totalling 1,975m had been completed on the porphyry area by the end of June.

Geological Setting

The Chanach Project (exploration licence AP6771) is located in the North Western part of the Kyrgyz Republic in the Jalal-Abad province and covers an area of 57.25 km[2] of the Chatkal Rangers inside the south-western Tien Shan metallogenic belt, which runs more than 1,500 km from Uzbekistan through to China and hosts one of the world’s largest open pit gold mines, Murantau (175 Moz) with production believed to be in the order of 2 million ounces per annum[2] .

A structural survey was conducted in 2022 showing occurrences of Cu-Au bearing magnetite skarns, indicating a larger porphyry centre as the key driver for mineralisation. Key findings of the structural survey were:

• 3km strike length of high-grade epithermal veins in the ‘central’ region

• Multiple copper intrusions in the ‘copper’ region over a 1.5km strike

• Multiple occurrences of magnetite skarns mapped over a 7km strike

• Historic rock grades >20g/t Au and 5% Cu

• Potential to extend tenement to east extending strike of skarns

BOUGAINVILLE INTERESTS – THE PANGUNA PROJECT OPPORTUNITY

RTG is the nominated development partner with the joint venture company established by the SMLOLA and Central in the Landowner proposal with respect to the redevelopment of the Copper-Gold Panguna Project located in the Central Region of the island of Bougainville, within the Autonomous Region of Bougainville, PNG. RTG owns just under 70% of Central, with additional loans to Central that can be converted to increase our interest. The proposal, being led by the SMLOLA, is a landowner initiative and will be subject to the success or otherwise of the SMLOLA in securing a role in the redevelopment of the mine and the minerals which are owned by the landowners exclusively represented by the SMLOLA.

The members of the SMLOLA are the owners of the customary land which is the subject of the old Panguna open pit mine, and in which the mineral resources of the Panguna mine are located.

The SMLOLA was established by the ABG nearly a decade ago to represent the customary owners of the land at the old Panguna pit. The SMLOLA constitution was prepared by the ABG legal officers representing the ABG Department of Justice and remains unchanged to this day.

The ABG established the SMLOLA as the Landowner Association to represent the Customary Owners of the land contained within the original but now expired Panguna Special Mining Licence - SML (hence the name SMLOLA, and the similarly EL 01), which covers the entire Panguna Open Pit area. This membership is automatic for those persons born into the 7 named villages, which comprise the customary land area within the SML.

The ABG and PNG Governments have announced that the holding of PNG in BCL is currently being transferred to the ABG, which will leave the ABG with just under 73% of BCL and should significantly assist with moving the Panguna Project forward.

Presidential Elections will occur in the second half of this calendar year, and we wish the candidates well.

RTG continues to work with the SMLOLA team and the community to progress meaningful and transparent discussions with the ABG on the redevelopment proposal for Panguna and support local community and social programs, reconciliations and unity programs.

RTG also continues to engage with the Toroama Government to understand how we can assist in their future plans for Bougainville, BCL and their people.

CORPORATE SUMMARY

On 31 March 2025, RTG announced it had received commitments to raise approximately A$19.5M (circa US$12.3M) in the Placement. On 9 April 2025, the Company announced it had successfully completed the issue of 169,297,750 Securities, with Tranche 1 raising proceeds of circa A$4.2M (before costs).

Shareholder approval for the issue of Tranche 2 Securities was obtained at the Company’s AGM on 23 May 2025. On 30 May 2025, RTG announced it had successfully completed the issue of 613,755,996 Securities raising proceeds of circa A$15.3M (before costs).
