• The impact of recent global fuel price increases was only partially felt during the Quarter (primarily in March 2026) and had a minimal overall effect on operating costs due to the processing plant’s use of grid power rather than diesel generation. Diesel prices increased from approximately US$0.80/l in January–February to US$1.45/l in March, with the rise of US$0.65/l resulting in an increase of approximately 10% in AISC for the month of March, primarily related to earthmoving activities. MOPS (Mean of Platts Singapore – barrel price) pricing during March ranged from US$115 to US$252, with the most recent price easing to US$198.

• The contracted fuel supplier to the Okvau Gold Mine has confirmed that it has secured a guaranteed diesel supply through to early June 2026 and will continue to provide regular updates regarding extensions to the secured supply period.
