“Deep drilling at both Jaguar South and Onça Preta continues to deliver outstanding results with intersections such as 21.0m at 2.26% Ni at Jaguar South and 36.0m at 1.27% Ni at Onça Preta from around 480 to 500m down-hole.
“These results have given us a great platform and the confidence to start the Jaguar Deeps program, which will mark an exciting new phase of exploration at Jaguar. We now have the capacity on-site to drill and carry out DHEM surveys down to 1,500m depth, which is almost twice as deep as any of our current drilling.
“The continued delivery of outstanding results from resource growth drilling and the start of the Jaguar Deeps program is consistent with the Company’s two-pronged strategy of continuing to grow the Jaguar Resource, in parallel with key de-risking steps associated with project permitting, completion of the ongoing Definitive Feasibility Study and ongoing strategic off-take discussions.”
Jaguar South Drill Results
Resource growth drilling continues to deliver with step-out holes at Jaguar South returning outstanding results. Drill hole JAG-DD-23-593 on section 478090mE intersected 19.0m at 2.13% Ni from 220.0m (including 11.0m at 3.31% N from 223.0m) and 22.0m at 1.92% Ni from 325.0m (including 9.0m at 3.43% Ni from 325.0m), as shown in Figure 1.
The upper intersection of JAG-DD-23-593 is immediately below the current planned pit limits and the thick highgrade nature of the intersection is likely to influence future pit optimisations (Figure 1), while the deeper intersection is at the base of the current MRE and is projected to contribute to additional resource growth.
Furthermore, the exciting Jaguar Deeps drilling program is now underway (program discussed further below). The deepest hole completed to date at Jaguar South is JAG-DD-22-445 on section 478300mE which intersected 20.4m at 3.94% Ni (including 9.5m at 5.59% Ni ) from 612.7m (Figure 1).
The first hole of the Jaguar Deeps drill program is a parent hole which is currently underway on section 478300mE targeting mineralisation more than 300m below JAG-DD-22-445 and the current base of the MRE . The parent hole has been designed so that it provides a platform for additional deeper wedge holes to be drilled further testing the down-dip and lateral extensions.
Drilling to date has identified consistent high-grade mineralisation on sections either side of 478300mE over at least 180m of strike and at depths greater than 600m from surface. DHEM conductor plates suggest that the strike of the high-grade shoot could be up to 300m wide and extend for at least 200m below the current deepest drilling.
Highlights of the new assay results received from drilling at the Jaguar South Deposit include the following downhole intervals (see Table 1 for complete results and plan map at Figure 2):

The Jaguar South Deposit is the largest deposit at the Jaguar Project, hosting an MRE of 34.6Mt at 0.92% Ni for more than 316kt of contained nickel . The base of the November 2022 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 2).

Onça Preta Results
Deep step-out drilling at the Onça Preta Deposit continues to intersect consistent semi-massive zones of highgrade nickel sulphides. Drill-hole JAG-DD-23-583 returned 36.0m at 1.27% Ni from 483.6m (including 6.0m at 2.02% Ni from 500.1m) and 11.2m at 1.01% Ni from 585.2m on section 476885mE. This intersection is around 60m downdip from JAG-DD-22-375, which intersected 20.8m at 1.54%Ni from 415.4m (Figure 3).
Furthermore, visual observations[2] from drill-hole JAG-DD-23-614, located on the same section (which is currently the deepest hole drilled to date at Onça Preta ) intersected multiple zones of stringer to semi-massive nickel sulphide mineralisation within broader mineralised intersections 200m down-dip from JAG-DD-23-583 and 100m below the limit of the November 2022 MRE. Refer to Figure 7 and Table 5 for photos of the core and visual estimates of hole JAG-DD-23-614.
Located 100m along strike on section 476985mE, drill hole JAG-DD-23-613 (the second deepest drill hole at Onça Preta) intersected additional zones of stringer to semi-massive nickel sulphide mineralisation. These intersections are 120m below the current MRE and demonstrate continuity of the high-grade nickel sulphide mineralisation both down-dip and along strike, which bodes well for resource growth and potential future underground operations. Refer to Figure 6 and Table 4 for photos of the core and visual estimates of hole JAG-DD-23-613.
The Jaguar Deeps program is now also underway at Onça Preta, with drilling designed to target the high-grade shoot more than 200m below the current deepest drilling and over 300m below the existing MRE limits. Successful intersections in the Jaguar Deeps drilling have the potential to significantly increase the down-dip extent of the Onca Preta Deposit.
2 Visual estimates are uncertain in nature and hence are in no way intended to be a substitute for analytical results. All intervals have been sampled and the analytical results will be reported to the market when the Company receives them.

The high-grade nickel sulphide mineralisation intersected continues to confirm the current interpretation of the NNE plunge towards the Puma Layered Mafic-Ultramafic Complex, with vectoring of the drilling coming from DHEM conductor plates that extend up to 200m below the deepest drilling.
The first parent hole at Onça Preta is underway which will allow wedge holes to test the mineralisation down-dip and laterally. Again, the holes will be surveyed by the Company’s EM survey team to establish EM plates that will help drive the directional drilling and wedge hole targeting.
New assay results from drilling at the Onça Preta Deposit include the following down-hole intervals (see Table 1 for complete results and plan map in Figure 4):

The Onça Preta Deposit is the highest-grade deposit at the Jaguar Project, with the November 2022 Mineral Resource Estimate (MRE) expanded to 14.2Mt at 1.23% Ni for more than 173kt of contained nickel. Now with 400m of strike and up to 700m of down-dip extent (Figure 4), the Onça Preta deposit demonstrates outstanding potential for significant ongoing resource growth.

Jaguar Deeps
The Company has optimised its drill contractor fleet and now has six diamond rigs on-site with a further reduction to three diamond rigs expected during the September Quarter. The RC rig was demobilised last quarter. Final results from the RC drill program can be found in Table 3.
Drilling is now focused on the strategic Jaguar Deeps drilling, which is underway. Initial parent holes that are underway are designed to step-out over 300m below the current deepest drill holes at the Jaguar South and Onça Preta Deposits. Once the parent holes are completed, wedge holes will be drilled that can further test both downdip or laterally along strike if required. The wedge hole directions will be driven and vectored by the DHEM surveys of the parent holes.

The hydrothermal nature of the mineralisation at the Jaguar Project is understood to be similar to that seen at the Salobo Copper-Gold Mine and points to a deep plumbing system which remains to be tested beyond the current drill depths at Jaguar (Figure 5). Down-dip extension of the Jaguar Deposits are currently around 600m from surface with successful drilling potentially doubling the down-dip extent of the mineralisation.

APPENDIX A – Compliance Statements for the Jaguar Project
The following Tables are provided for compliance with the JORC Code (2012 Edition) requirements for the reporting of Exploration Results at the Jaguar Project.
SECTION 1 - SAMPLING TECHNIQUES AND DATA
(Criteria in this section apply to all succeeding sections).
| Criteria | Commentary |
|---|---|
| Sampling techniques | • Historical soil sampling was completed by Vale. Samples were taken at 50m intervals along 200m spaced north-south grid lines. • Surface material was first removed, and sample holes were dug to roughly 20cm depth. A 5kg sample was taken from the subsoil. The sample was placed in a plastic sample bag with a sample tag before being sent to the lab. • Surface rock chip/soil samples were collected from in situ outcrops and rolled boulders and submitted for chemical analysis. • The historical drilling is all diamond drilling. Drill sections are spaced 100m apart and generally there is 50 to 100m spacing between drill holes on sections. • Core was cut and ¼ core sampled and sent to commercial laboratories for physical preparation and chemical assay. • At the laboratories, samples were dried (up to 105°C), crushed to 95% less than 4mm, homogenized, split and pulverized to 0.105mm. A pulverized aliquot was separated for analytical procedure. • Sample length along core varies between 0.3 to 4.0m, with an average of 1.48m; sampling was done according to lithological contacts and generally by 1m intervals within the alteration zones and 2m intervals along waste rock. • Current drilling is being completed on spacing of 100m x 50m or 50m x 50m. Sample length along core varies between 0.5 to 1.5m • Core is cut and ¼ core sampled and sent to accredited independent laboratory (ALS). • For metallurgical test work continuous downhole composites are selected to represent the metallurgical domain and ¼ core is sampled and sent to ALS Metallurgy, Balcatta, Perth. • Samples from RC drilling are split to make 3-5kg samples. The sample is placed in a plastic sample bagwith a sample tagbefore beingsent to the laboratory. |
| Drilling techniques | • Historical drilling was carried out between 2006 to 2010 by multiple drilling companies (Rede and Geosol), using wire-line hydraulic diamond rigs, drilling NQ and HQ core. • Vale drilled 169 drill holes for a total of 56,592m of drilling in the resource area. All drill holes were drilled at 55⁰-60⁰ towards either 180⁰ or 360⁰. 530 Centaurus drill holes (459 diamond for 96,318m and 71 RC for 10,020m) for a total of 106,158m of drilling on the project. There are a further 40 diamond holes drilled that were used for the model interpretation, but either were not assayed as they are dedicated geotech or metallurgical bulk sample holes or assays remain pending and as such were not included in the model interpolation. Most drill holes were drilled at 55⁰-75⁰ towards either 180⁰ or 360⁰. • Current drilling is a combination of HQ and NQ core (Servdrill). • The current RC drilling is completed by Geosenda Sondagem using a face sampling hammer (4.5”). Sample is collected from the sample cyclone in large plastic sample bags. Samples are then split either by riffle splitters or manually (fish bone method) where there is high moisture content. • All RC holes were sampled on 1m intervals. Sample size, sample recovery estimate and conditions were recorded. |
| Drill sample recovery | • Diamond Drilling recovery rates are being calculated at each drilling run. • For all diamond drilling, core recoveries were logged and recorded in the database for all historical and current diamond holes. To date overall recoveries are >98% and there are no core loss issues or significant sample recovery problems. • To ensure adequate sample recovery and representativity a Centaurus geologist or field technician is present during drilling and monitors the sampling process. • No relationship between sample recovery and grade has been demonstrated. No bias to material size has been demonstrated. • RC sample weights are taken for all samples and a recovery estimate are made where the sample is not wet. Where the sample is wet a visual estimate of the sample recovery is made. The estimated recovery is approximately 90%, which is considered acceptable for the deposit type. • To ensure the representative nature of the sample, the cyclone and sample hoses are cleaned after each metre of drilling, the rig has two cyclones to facilitate the process. Additionally, extra care is taken when drilling through the water table or other zones of difficult ground conditions. • Noquantitative twinned drillinganalysis has been undertaken at theproject to date. |

| Logging | • Historical outcrop and soil sample points were registered and logged in the Vale geological mapping point database. • All drill holes have been logged geologically and geotechnically by Vale or Centaurus geologists. • Drill samples are logged for lithology, weathering, structure, mineralisation and alteration among other features. Logging is carried out to industry standard and is audited by Centaurus CP. • Logging for drilling is qualitative and quantitative in nature. • All historical and new diamond core has been photographed. • Geologists complete a visual log of the RC samples on 1m intervals at the time of drilling. Logging captures colour, rock-type, mineralogy, alteration and mineralisation style. Logging is both qualitative and quantitative. • Chiptrays have been collected, photographed and stored for all drill holes to-date. |
| Sub-sampling techniques and sample preparation |
• Diamond Core (HQ/NQ) was cut using a core saw, ¼ core was sampled. Sample length along core varies between 0.3 to 4.0m, with an average of 1.48m; sampling was done according to lithological contacts and generally by 1m intervals within the alteration zones and 2m intervals along the waste rock. • There is no non-core sample within the historical drill database. • For RC sampling 1m samples are taken from the cyclone and then split by rifle splitter (if dry) or manually (if wet) using the fish-bone technique. Sample weight is between 3-5kg. • QAQC: Standards (multiple standards are used on a rotating basis) are inserted every 20 samples. Blanks have been inserted every 20 samples. Field duplicates are completed every 30 samples. Additionally, there are laboratory standards and duplicates that have been inserted. • Centaurus has adopted the same sampling QAQC procedures which are in line with industry standards and Centaurus’s current operating procedures. • Sample sizes are appropriate for the nature of the mineralisation. • All historical geological samples were received and prepared by SGS Geosol or ALS Laboratories as 0.5-5.0kg samples. They were dried at 105°C until the sample was completely dry (6-12hrs), crushed to 90% passing 4mm and reduced to 400g. The samples were pulverised to 95% passing 150µm and split further to 50g aliquots for chemical analysis. • New samples are being sent to ALS Laboratories. The samples are dried, crushed and pulverised to 85% passing 75µm and split further to 250g aliquots for chemical analysis. • During the preparation process grain size control was completed by the laboratories (1 per 20 samples). • Metallurgical samples are crushed to 3.35mm and homogenised. Samples are then split to 1kg sub- samples. Sub-samples areground to specific sizes fractions(53-106µm)for flotation testwork. |
| Quality of assay data and laboratory tests |
• Chemical analysis for drill core and soil samples was completed by multi element using Inductively Coupled Plasma ICPAES (multi-acid digestion); ore grade analysis was completed with Atomic Absorption (multi-acid digestion); sulphur analysis was completed with Leco, and Au and PGEs completed via Fire Assay. • New samples are being analysed for 48 elements by multi element using ME-MS61 (multi-acid digestion) at ALS Laboratories; ore grade analysis was completed with ICP-AES (multi-acid digestion); sulphur analysis was completed with Leco, and Au and PGEs completed via Fire Assay. • ALS Laboratories insert their own standards at set frequencies and monitor the precision of the analysis. The results reported are well within the specified standard deviations of the mean grades for the main elements. Additionally, ALS perform repeat analyses of sample pulps at a rate of 1:20 (5% of all samples). These compare very closely with the original analysis for all elements. • Vale inserted standard samples every 20 samples (representing 5%). Mean grades of the standard samples are well within the specified 2 standard deviations. • All laboratory procedures are in line with industry standards. Analysis of field duplicates and lab pulp duplicates have returned an average correlation coefficient of over 0.98 confirming that the precision of the samples is within acceptable limits. • Vale QAQC procedures and results are to industry standard and are of acceptable quality. • All metallurgical chemical analysis is completed byALS laboratories |
| Verification of sampling and assaying |
• All historical samples were collected by Vale field geologists. All assay results were verified by alternative Vale personnel. The Centaurus CP has verified the historical significant intersections. • Centaurus Exploration Manager and Senior Geologist verify all new results and visually confirm significant intersections. • Twin holes have been completed of both historical drilling and DD/RC drilling. There is good correlation between both drilling campaigns and sample bases. • All primary data is now stored in the Centaurus Exploration office in Brazil. All new data is collected on Excel Spreadsheet, validated and then sent to independent database administrator (MRG) for storage (DataShed). • No adjustments have been made to the assaydata. |

| Location of data points | • All historical collars were picked up using DGPS or Total Station units. Centaurus has checked multiple collars in the field and has confirmed their location. All field sample and mapping points were collected using a Garmin handheld GPS. • An aerial survey was completed by Engemec Topografia and has produced a detailed surface DTM at (1:1000 scale). • The survey grid system used is SAD-69 22S. This is in line with Brazilian Mines Department requirements. • New drill holes are sighted with handheld GPS and after completion picked-up by an independent survey consultant periodically. Downhole survey for all the historical drill holes and Centaurus hole up to JAG-DD-19-012 used Maxibor equipment. All new drill holes are being downhole surveyed usingReflex digital down-hole tool,with readings everymetre. |
| Data spacing and distribution |
• Soil samples were collected on 40m spacing on section with distance between sections of 200m and 400m depending on location. • Sample spacing was deemed appropriate for geochemical studies. • The historical drilling is all diamond drilling. Drill sections are spaced 100m apart and generally there is 50 to 100m spacing between drill holes on sections. Centaurus is in the process of closing the drill spacing to 100m x 50m or 50m x 50m. • No sample compositing was applied to the drilling. • Metallurgical samples to date have been taken from Jaguar South, Jaguar Central, Jaguar North, Jaguar Northeast,Jaguar Central North and Onça Preta. |
| Orientation of data in relation to geological structure |
• Historical drilling was oriented at 55⁰-60⁰ to either 180⁰ or 360⁰. This orientation is generally perpendicular to the main geological sequence along which broad scale mineralisation exists. • Mineralisation is sub-vertical; the majority of the drilling is at low angle (55-60⁰) in order to achieve intersections at the most optimal angle. |
| Sample security | • All historical and current samples are placed in pre-numbered plastic sample bags and then a sample ticket was placed within the bag as a check. Bags are sealed and then transported by courier to the ALS laboratories in Vespasiano, MG. • All remnant Vale diamond core has now been relocated to the Company’s own core storage facility in Tucumã,PA. |
| Audits or reviews | • The Company is not aware of any audit or review that has been conducted on the project to date. |
SECTION 2 - REPORTING OF EXPLORATION RESULTS
(Criteria listed in the preceding Section also apply to this section).
| Criteria | Commentary |
|---|---|
| Mineral tenement and land tenure status |
• The Jaguar project includes one exploration licence (856392/1996) for a total of circa 30km2. A Mining Lease Application has been lodged that allows for ongoing exploration and project development ahead of project implementation. • The tenement is part of a Sale & Purchase Agreement (SPA) with Vale SA. One final deferred consideration payment totalling US$5.0M (on commencement of commercial production) and a production royalty (2.00% on a nickel concentrate product or 1.75% on a nickel sulphate product) are to follow. Centaurus has taken on the original obligation of Vale to BNDES for 1.8% Net Operating Revenue royalty. • Mining projects in Brazil are subject to a CFEM royalty, a government royalty of 2% on base metal revenue. • Landowner royalty is 50% of the CFEM royalty. • Centaurus has secured possession rights to three properties over the Jaguar Project. The agreements remove exposure to the landowner royalty over the properties secured. • The project is covered by a mix of cleared farmland and natural vegetation. • The project is not located within any environmental protection zones and exploration and mining is permitted with appropriate environmental licences. |
| Exploration done by other parties |
• Historically the Jaguar Project was explored for nickel sulphides by Vale from 2005 to 2010. |
| Geology | • Jaguar Nickel Sulphide is a hydrothermal nickel sulphide deposit located near Tucumã in the Carajás Mineral Province of Brazil. • Jaguar is located at the intersection of the WSW-trending Canaã Fault and the ENE-trending McCandless Fault,immediatelysouth of the NeoArchean Puma Layered Mafic-Ultramafic Complex. |
