• Simberi Operations has sufficient diesel fuel stocks for over 3 months of mining and power generation
• Diesel is supplied by Puma Energy and originates from various refineries in Asia
• St Barbara has been holding increased diesel storage for several months

St Barbara Limited (ASX:SBM) has advised that its Simberi Operations is well stocked with diesel fuel, with current stocks sufficient to cover more than two months' usage on the island and another 3.5 million litres in allocated storage in the country, totaling over 3 months of requirements for mining and power generation. The diesel is supplied by Puma Energy (majority owned by the Trafigura Group) and originates from various refineries in Asia, including Singapore, Malaysia, South Korea and Japan. St Barbara has been taking the precaution of holding increased diesel storage for several months now, with the pricing of 6.4 million litres of the stored diesel locked in and paid for based on pre-conflict pricing. While 1.8 million litres of the diesel in storage at Lae will only be priced at the end of March 2026, the company is well-positioned to weather any potential disruptions to global diesel fuel supply chains.
