JAGUAR NICKEL PROJECT – POWER SUPPLY UPDATE

• Equatorial Pará Distribuidora de Energia S.A. (Equatorial) has informed Centaurus of required upgrades to power transmission capacity in order to meet the Jaguar Project’s power requirements.

• The power grid upgrade process is planned to deliver significantly expanded power transmission capacity to the region to support the development of Jaguar and other major mineral projects.

• The proposed timing to complete the transmission capacity upgrade is consistent with the Jaguar Project’s current development timeline.

Centaurus Metals (ASX Code: CTM, OTCQX: CTTZF) advises that it was informed by Equatorial Pará Distribuidora de Energia S.A. (Equatorial), a key energy distribution and power provider in the Carajás Province, of the need to upgrade transmission capacity to the Company’s planned, and Ministry of Mines and Energy (MME) approved, connection point in order to meet the long-term power requirement for the Jaguar Nickel Project.

The MME had previously approved the Jaguar Project’s request for 47MW of power, with this approval being based on the assessment that the required supply could be met from existing network capacity.

Centaurus requested a trading halt in its securities while its team in Brazil sought clarification of the situation.

At a meeting on Tuesday in Belem, Equatorial advised the Company that Empresa de Pesquisa Energética (EPE - MME’s planning department responsible for energy) is currently undertaking a detailed study to increase transmission capacity in the region where the Project is located, for Jaguar and other proponents. The Company has been informed that this study is due to be completed by December 2025.

The region where Jaguar is located has recently seen a significant increase in future power demand requirements, mainly due to mining projects such as Centaurus’ Jaguar Nickel Sulphide Project, Ero’s Tucumã Copper Project, the expansion of Vale’s Onça Puma operations for a second kiln and the Pantera Copper Project.

Upon completion of the EPE study, steps will be initiated to implement the preferred transmission upgrade solution.

Based on recent discussions with the various key Brazilian energy supply agencies, the power grid upgrade process should deliver expanded power transmission capacity to the region consistent with the Jaguar Project’s current development timeline.

The Company will work closely with these agencies to ensure that the advised timeline for the transmission capacity expansion remains on track to support the development of the Project. Concurrently, the Company will continue to assess other short-term power options in case there is slippage in the power grid upgrade process to ensure the Project timeline remains on track.

Centaurus’ Managing Director, Mr Darren Gordon said: “Following the advice from Equatorial earlier this week that upgraded power transmission was required to meet Jaguar’s long term power requirements, our team in Brazil moved quickly to clarify the situation and I am pleased to say that we had a very positive and constructive meeting with the Equatorial on Tuesday, Brazil time. It is very pleasing to see that the Brazilian Government is directly considering the Jaguar Project, and other significant mining projects owned by major mining houses in the region, as part of the future expansion of the transmission capacity.
