AUSTRALIAN SECURITIES EXCHANGE ANNOUNCEMENT
& MEDIA RELEASE
The results are expected to contribute to an increase in the global Mineral Resource Estimate (MRE), due for delivery at the end of September, as well as to upgrade more of the Jaguar MRE into the higher-confidence Measured and Indicated categories in advance of Ore Reserve estimation as part of the DFS.
onlyCentaurus' Managing Director, Mr Darren Gordon, said: "The resource development in-fillprogram has been our focus for the past six months and continues to demonstrate the consistency and quality of the nickel sulphide mineralisation that sits within the planned open pit limits.
"We are confident that these results will push the majority of the upcoming MRE into the higher confidence Measured and Indicated Resource categories that will, in turn, underpin a maiden Ore Reserve Estimate for the Definitive Feasibility Study. This represents a major step to de-risking the Jaguar Project.
"It's also great to see the existing deposits continuing to grow, with outstanding step-out results of up to 31.7m at use1.61% Ni received from below the current MRE limits at Onça Preta. This is further supported by our deepest hole on the project to date, which stepped-off over 120m down-dip targeting DHEM conductor plates. Visual inspection
of this step-out hole has confirmed the presence of semi-massive sulphides.
"We are quickly approaching the completion of the current Resource development in-fill drilling program for the pcoming MRE and, once we do, we will immediately swing the majority of the 15 rigs across to Resource Growth
and greenfields discovery drilling - which should make for a very interesting second half of 2022 at Jaguar."
personalResource Growth - Step-out Drilling
While drilling has so far been focused on the in-fill program that is required for the upgrade and development of the Jaguar Resource, 2-3 rigs have been designated to specifically target resource growth by undertaking step-out drilling at the Onça Preta and Jaguar South Deposits.
The current base of both the Onça Preta and Jaguar South Deposits has now been extended well below the base f the underground operations identified in the May 2021 Jaguar Project Scoping Study, which was already re tricted by the base of the March 2021 MRE. Any new resource tonnes generated by step-out drilling are therefore expected to result in growth of the overall MRE and, in time, contribute to future underground
operations. Onça Preta
The December 2021 Mineral Resource Estimate (MRE) expanded the Onça Preta Deposit to 5.2Mt at 1.52% Ni for more than 78kt of contained nickel. Onça Preta is the highest-grade deposit at the Jaguar Project.
Step-out drilling continues to intersect semi-massive and massive zones of nickel sulphides including 31.7m at For1.61% Ni and 13.5m at 1.26% Ni in JAG-DD-22-263 on section 476885mE and 22.7m at 1.47% Ni in JAG-DD-22-284 n section 476935mE (Figure 1). Both drill-holes intersected mineralisation below the base of the December 2021
MRE, indicating a likely increase in the MRE due for delivery at the end of September 2022.
Importantly, drill hole JAG-DD-22-3752, the deepest hole drilled to date at Onça Preta, has intersected 20m of semi- massive nickel sulphide mineralisation within a broader mineralised intersection a further 50m down-dip from JAG- DD-22-263, highlighting the potential for further resource growth. For photos of the core and visual estimates of hole JAG-DD-22-375, see Figure 10 and Table 3.

The 2022 drilling of the Onca Preta and Onça Rosa Deposits is part of a push to extend the high-grade underground ForResources at depth with the support of the new Down-Hole Electromagnetic (DHEM) probe, which has the capacity
to survey down to a depth of 750m down-hole.Jaguar South
The Jaguar South Deposit is the largest deposit at the Jaguar Project, hosting an MRE of 27.6Mt at 0.93% Ni for more than 257kt of contained nickel, including an Indicated component of 13.9Mt at 1.01% Ni for 140kt of contained nickel.
The base of the December 2021 MRE continues to be constrained by the depth of drilling and ongoing step-out drilling continues to confirm that the mineralisation remains open at depth and along the +800m strike length of the deposit in both directions (see Figure 8).

Step-out drilling at Jaguar South includes JAG-DD-22-3413, which has intersected 10m of stringer and semi-massive nickel sulphide mineralisation within a broader mineralised intersection more than 120m down-dip from JAG-DD-21-164 (16.0m at 1.32% Ni). For photos of the core and visual estimates of hole JAG-DD-22-341, see Figure 11 and Table 4.

conductor plates in light blue.
This intersection is more than 70m below the limits of the December 2021 MRE. The confidence in stepping-out over 120m down-dip is driven by the DHEM conductor plates, along with a continual improvement of the geological
Forinterpretations and the developing structural model.
Once resource definition drilling is completed in the coming weeks and the mineralisation within the optimised pit shell has been upgraded to the higher confidence Measured and Indicated Resource categories, the drill rigs will be moved onto resource growth (extensional and step-out) and greenfields discovery drilling.
