ShapshotDuring December 2023 quarter, key permitting milestones were achieved. Technical approval of the Plan of Economic Exploitation (PAE/Mining Lease Application) received. Environmental Impact Assessment (EIA) and Preliminary Licence (LP) also approved by Pará State Environmental Committee (COEMA).

March 1, 2024 - Centaurus reshapes Jaguar DFS to focus on concentrate project in response to changed nickel market conditions. The Centaurus Board decided to reshape the current Feasibility Study – deferring the parts of the study relating to a fully integrated downstream nickel sulphate project and focusing instead on completing the Feasibility Study based on an initial nickel concentrate-only project. The development of a potential downstream refinery can be considered in future when market conditions improve.

Centaurus is expected to deliver the Jaguar Concentrate Feasibility Study by the end of June 2024.

Summary:

The various deposits at the JNP differ from most nickel sulphide deposits mined to date globally because they are of hydrothermal origin, with the nickel sulphide mineralisation being of high tenor (tenor referring to the Ni concentration in 100% sulphides) with low Cr and Mg content and not directly associated with mafic-ultramafic rocks. It is interpreted that the JNP mineralisation represents a hybrid hydrothermal style between magmatic Ni-Cu-PGE sulphide and IOCG mineralisation.

The JNP is located in the Carajás Mineral Province (Carajás), which contains one of the world’s largest known concentrations of large tonnage IOCG deposits.

The Jaguar mineralised bodies are hosted within sheared sub-volcanic porphyritic dacites of the Serra Arqueada Greenstone belt, adjacent to the boundary with a tonalite intrusive into the Xingu basement gneiss, while Onça Preta and Onça Rosa are tabular mineralised bodies hosted within the tonalite. The hydrothermal alteration and mineralisation form sub-vertical to vertical bodies structurally controlled by regional ductile-brittle mylonitic shear zones.

Sulphide assemblages are similar in both ore types, differing only in modal sulphide composition and structure. The mean sulphide assemblage (in order of abundance) is pyrite, pentlandite, millerite, violarite, pyrrhotite and sphalerite with trace vaesite, nickeliferous pyrite and chalcopyrite.

The most abundant type constitutes low-grade nickel mineralisation, occurring within veins concordant with the foliation, that is associated with the biotite-chlorite alteration. The target high-grade nickel mineralisation is associated with the magnetite-apatite-quartz alteration. It occurs as veins and breccia bodies consisting of irregular fragments of extensively altered host rocks within a sulphide-magnetite-apatite rich matrix. Mineralised breccias form semi-massive sulphide bodies up to 30m thick parallel to, or crosscutting, biotite-chlorite rich zones.

Mineralisation at the Onça Preta and Onça Rosa deposits is predominantly of the second type, forming tabular semi-continuous to continuous bodies both along strike and down dip. Regolith at the deposit is in-situ and comprises a thin soil layer overlying a decomposed saprolite transitional zone. The thickness to the base of the transitional zone generally varies from 5m to 25m (max. 34m). Within the JNP tenement there are also several untested targets characterised by magnetic and/or electromagnetic anomalies located along favourable structures.
