24 The Company tests the effectiveness of these training programs and safety initiatives by recording and reporting health and safety performance across the business. By doing so, we expect to see safety performance improvements year-on-year where proactive (lead indicator) actions taken are having a positive effect on the lag indicators though a reduction in the frequency rate of hazards and incidents. The parameters used to measure performance are based on the number of incidents/ injuries per million hours worked on a rolling 12-month basis and include: > LTIFR – lost time injury frequency rate > RWIFR – restricted work injury frequency rate (where restricted work injuries encompass all injuries that do not cause lost time, but restrict the worker from performing their normal duties for any time after the accident) > TRIFR – total reportable injury frequency rate (LTIFR + RWIFR) Given that comparative safety performance data for other exploration companies and mineral resource industries are not published for Brazil, Centaurus compares our performance with the latest data for the Western Australian exploration industry, as displayed in the following Safety Performance Rate graph. Centaurus’ LTIFR for 2025 remained at Nil. The benchmark LTIFR for the Western Australian exploration industry is 2.6, which is a great safety achievement for Centaurus. The TRIFR for 2025 was Nil. The benchmark TRIFR for the Western Australian exploration industry is 3.8. Importantly, there were no fatalities or serious injuries across Centaurus’ activities during the reporting period. All injuries that required medical assistance, even those without lost time or restriction of work, are formally reported to Brazilian regulators. In 2025, Centaurus continued utilising the OHS management software, SICLOPE, which is structured with various operational modules. The software generates an ID card with a QR code for every employee on site, enabling verification of the status of each worker’s site access requirements. Routine safety inspections and hazard identification are undertaken using a mobile device application, with reports digitally recorded and leaders immediately alerted to any serious findings. 24 2025 SAFTY PERFORMANCE RATES 2.6 3.8 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 Jan-25 Feb-25 Mar-25 Apr-25 May-25 Jun-25 Jul-25 Aug-25 Sep-25 Oct-25 Nov-25 Dec-25 y CTM 12-month LTIFR moving average WA 2023-2024 LTIFR Exploration average* CTM 12-month TRIFR moving average WA 2023-2024 TRIFR Exploration average* First aid simulation training
