Kiniero Gold Project – January 2026 Progress

Nampala Gold Operation, Mali

¹ Financial information for the Nampala Gold Operation, Mali is unaudited. Figures may be subject to further adjustments.

Operation summary

• Material Mined: During the December 2025 quarter, total material mined was 2,534,890 tonnes, comprising 2,016,593 tonnes of waste and 518,297 tonnes of ore. The stripping ratio decreased to 3.89, representing a 13.2% reduction from 4.48 in the September 2025 quarter. This reduction reflects the completion of elevated waste stripping activities undertaken in the prior quarter, which was strategically focused on removing overburden to facilitate access to deeper ore zones.
• Ore Processed: A total of 582,618 tonnes of ore were processed during the December 2025 quarter, representing a 16.2% increase from 501,300 tonnes in the September 2025 quarter. The increase in throughput was primarily driven by improved plant availability, fewer chute blockages, reduced ore clogging as rainfall subsided, and fewer electrical and instrumentation-related interruptions.
• Head Grade: Average head grade for the December 2025 quarter was 0.68 g/t, down 1.4% from 0.69 g/t in the September 2025 quarter. This modest decline reflects the processing of a predominantly medium-grade ore blend, as higher-grade ore within the pits required additional blasting prior to excavation and delivery to the mill. Despite the reduction, the grade remains in line with the mine plan and grade control parameters.
• Recovery Rate: Gold recovery for the December 2025 quarter was 87.2%, broadly consistent with 88.4% in the September 2025 quarter. The slight decrease reflects normal processing variability during the period, including a marginal increase in gold reporting to tailings. Overall recovery performance remains in line with operational expectations.
• Gold Production: Gold production for the December 2025 quarter totalled 11,028 ounces, an increase of 1,254 ounces compared to the September 2025 quarter. The improvement in production was driven by higher processing plant ore throughput.

Environmental and Safety Performance

• One Lost time injury (LTI) occurred in November involving one contractor at the West Pit. Since then, 345,886 LTI-free man hours have been recorded.
• No reportable environmental incidents or breaches were recorded during the period.
• Environmental monitoring programs continued for noise, water and air quality.

Community and Social Responsibility

Robex continued to support local communities at the Nampala Mine during Q4 2025, reinforcing its commitment to sustainable development and community engagement:

Key initiatives included:

• Contribution of approximately US$364,000 to the local Mining Development Fund.
• Education and training initiatives, including 28 vocational training or skills development internships for young Malians, and the distribution of school kits to students in Finkolo, Nampala, N’Tjikouna and N’Golola.
• Local partnerships and employment initiatives, including market garden purchases for women’s associations and engagement of community services provided through GIE Balimaya.
• Community donations, including support for youth sporting competitions, the CAPEMA orphanage in Sikasso, and 23 people with disabilities in Finkolo, Ganadougou and N’Tjikouna.
• Extensive local and national procurement, supporting regional suppliers and strengthening economic opportunities in the Sikasso region and across Mali.

Exploration and Development

During the quarter, Robex advanced exploration activities across its West African exploration portfolio, maintaining a focus on near-term production opportunities and long-term resource growth at Kiniero and Nampala.

Kiniero Gold Project, Guinea

• A detailed program of structural and lithological mapping was completed by specialist consultant Dr Alistair Reed of QMap Pty Ltd, improving understanding of geological controls on gold mineralisation across the Kiniero district and refining priority exploration targets for diamond and reverse circulation (RC) drilling programs.
• A diamond drilling program commenced in late October at Sector Gobele Area, comprising five holes for a total of 1,956 metres. The program aims to vector toward the centre of the volcanic system, assess the potential for an “Expanded Sector Gobele” open pit, and test depth extensions below existing mineralisation. Multiple zones of alteration and sulphide mineralisation were intersected, with assays pending.
• A reverse circulation drilling program at Sabali South comprised 29 holes for 4,540 metres, targeting the Sabali-Mansounia mineralised corridor and evaluating the potential development of a Kiniero “Super-Pit”, testing both lateral and depth extensions of known mineralisation.
• A sterilization RC drilling program was also completed across the Sector Gobele waste dump area and Sabali South MOP, with seven holes drilled. Results are pending.

Nampala Near-Mine Exploration, Mali

• Exploration remained focused on short- to medium-term, low strip ratio, free-dig oxide opportunities near existing processing infrastructure.
• A large-scale RC drilling program on the Mininko Exploration Permit comprised 207 holes for 19,916 metres, drilled at nominal 25m x 25m spacing. The program tested shallow oxide mineralisation within approximately 10 km of the Nampala processing plant, aimed at identifying low-cost sustaining and replacement feed options to extension of the current life-of-mine inventory.
• The program successfully identified two new mineralised targets, which will be advanced through further geological interpretation, preliminary Mineral Resource modelling and mine optimisation studies, subject to ongoing technical assessment.
