The auger drilling at Itapitanga continues to demonstrate that the nickel‐cobalt laterite mineralisation occurs from surface, with high grades of both nickel and cobalt mineralisation intersected to depths of 12m prior to drill refusal occurring.
The Itapitanga Project is located in the Carajás Mineral Province, a tropical region that hosts deep weathering profiles generally to 50m and often up to 100m. The high‐grade nickel‐cobalt laterite mineralisation is hosted within this weathered profile.
Anglo American’s neighbouring world‐class Jacaré Ni‐Co Deposit, one of the highest large‐tonnage nickel‐cobalt grades in the world with Mineral Resource of 307Mt at 1.3% Ni and 0.13% Co, including a high‐grade cobalt resource of 185Mt at 1.2% Ni and 0.18% Co[1] , is hosted in a laterite profile that is mineralised from surface down to an average depth of 40‐50m.
RC drilling will now be done to determine the full width and grade of the nickel‐cobalt mineralisation at the Project. Accordingly, the Company has recently executed a 5,000m RC drill contract with specialist Brazilian RC drilling group, Geosenda Perfurações Especiais. The rig is now being mobilised and drilling is set to start mid‐April.

Management Comment
Centaurus’ Managing Director, Darren Gordon, said the latest results supported the Company’s view that Itapitanga is a highly promising nickel‐cobalt project with scale and grade.
“To have numerous continuous intersections of high grade nickel and cobalt from surface to the bottom of the auger hole is exceptional and the fact that 29 of these first 33 holes finished in mineralisation is highly encouraging,” Mr Gordon said.
“We have so far defined a strike length of 3.3km with widths of up to 500m at the Northern Target and have recently started auger drilling on the Southern Target.
AUSTRALIAN SECURITIES EXCHANGE ANNOUNCEMENT & MEDIA RELEASE

“Mobilisation of a RC rig has commenced for the maiden RC drill program that is set to start in mid‐April. Given the mineralisation profile of the neighbouring Jacaré deposit, which hosts one of the highest large‐tonnage nickel‐ cobalt grades in the world, we’re confident that the RC drilling can extend the current mineralised intersections significantly.
“With the EV space driving the cobalt prices towards US$100,000/t along with a positive outlook for nickel we are looking forward to start delivering quality nickel and cobalt drill results from the RC drilling from early May.”

APPENDIX B – TECHNICAL DETAILS OF THE ITAPITANGA NICKEL‐COBALT PROJECT, JORC CODE, 2012 EDITION – TABLE 1 SECTION 1 SAMPLING TECHNIQUES AND DATA
| Criteria | Commentary | ||||
|---|---|---|---|---|---|
| Sampling techniques | Soil samples were collected at roughly 100‐150m intervals along a fence line oblique to the | ||||
| mineralisation. Surface material was first removed and sample holes were dug to roughly | |||||
| 30cm depth. A 2‐3kg 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 for | |||||
| chemical analysis. | |||||
| Channel samples were taken at a road cutting site vertically across the profile. The channel | |||||
| sample height was 2.5m, approximately 3‐5kg of sample was collected. | |||||
| Auger samples are taken by a hand‐held auger. Initial sections are 400m apart with 100m | |||||
| between holes. Care is taken to try to remove up‐hole contamination from the auger bit | |||||
| during sampling. A 3‐5kg sample was taken from the bit. The sample was placed in a plastic | |||||
| sample bagwith a sample tagbefore beingsent to the lab. | |||||
| Drilling techniques | Auger drilling completed using a hand‐held auger with a 200mm auger bit. Drilling depth is | ||||
| determined bydrill refusal. | |||||
| Drill sample | recovery | Not applicable. | |||
| Logging | All outcrop and soil sample points were registered and logged in the Centaurus geological | ||||
| mapping points database. | |||||
| Sub‐sampling | All geological samples were received and prepared by SGS Geosol Laboratories in | ||||
| techniques and sample | Parauapebas, Brazil as 0.5‐5kg samples. They were dried at 105°C until the sample was | ||||
| preparation | completely dry (6‐12hrs), crushed to 90% passing 3mm and reduced to 200‐300g. The | ||||
| samples were pulverised to 95% passing 150µm and split further to 50g aliquots for | |||||
| chemical analysis. | |||||
| Quality | of assay | data | Chemical analysis for metal oxides is determined using XRF analysis (XRF79C). Fusion disks | ||
| and laboratory tests | are made with pulped sample and the addition of a borate based flux. Analysis at SGS is for | ||||
| a 12 element suite. LOI using loss determination by thermo‐gravimetric analysis at 1000°C. | |||||
| Chemical analysis was completed for gold by fire assay and ICP for limit of 0.001ppm as well | |||||
| as multi element using ICP (IC40B) for select samples. | |||||
| SGS Geosol Laboratories insert their own standards at set frequencies and monitor the | |||||
| precision of the XRF and ICP analysis. These results reported well within the specified 2 | |||||
| standard deviations of the mean grades for the main elements. | |||||
| Additionally, the labs 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. | |||||
| Laboratory procedures are in line with industrystandards. | |||||
| Verification | of | All samples were collected by Centaurus field geologists. All assay results were verified by | |||
| sampling and assaying | alternative Company personnel and the Competent Person before release. | ||||
| Location | of | data | The survey grid system used is SAD‐69 22S. This is in line with Brazilian Mines Department | ||
| points | requirements. No mapping points are reported. | ||||
| Data | spacing | and | Initial soil samples were collected on 100‐150m spacing along a fence line. | ||
| distribution | In future, soils sampling will be conducted on 200‐400m line spacing with 50m between | ||||
