AUSTRALIAN SECURITIES EXCHANGE ANNOUNCEMENT & MEDIA RELEASE

The Exploration Target for the Itapitanga Nickel‐Cobalt Project currently stands at 35‐45Mt at 0.80% to 1.10% nickel, 0.07% to 0.12% cobalt and 18g/t to 30g/t scandium. Centaurus cautions that the potential quantity and grade of the Exploration Target is conceptual in nature and to date there has been insufficient exploration to define a JORC compliant Mineral Resource. It is also uncertain if further exploration and resource development work will result in the estimation of a Mineral Resource.
For full details of the Exploration Target please refer to the Company’s ASX Release of 1 August 2018.
A Phase 2 drilling program is being planned with the aim of allowing the Company to prepare a maiden JORC Mineral Resource estimate for the project. Any future drilling, however, will only be possible after the Company has secured the appropriate RC drill licence for the wetland and vegetated areas at the project.
Daniel’s Creek Fault Zone
The focus of the recent hand‐held auger drilling has been on the Daniel’s Creek Fault Zone (the central part of the Northern Target), where the first phase of RC drilling returned some of the project’s best assay results, including ITAP‐RC‐18‐127 ( 32m at 1.02% Ni and 0.13% Co ) and ITAP‐RC‐18‐139 ( 15.0m at 0.92 % Ni and 0.22% Co ).
Mineralised intercepts are broader and of higher nickel and cobalt grades in association with structural features. These structures facilitate the supergene process, which furthers the concentration of the nickel and cobalt mineralisation and deepens the mineralised profile.
RC drilling was not possible in the Daniel’s Creek Fault Zone during the maiden campaign under the existing drilling permit. Auger drilling has been able to continue in areas where no vegetation clearing is required and was successful in intersecting high grade nickel‐cobalt laterite mineralisation (represented by the red triangles in Figure 1).
While numerous auger holes were able intersect the top of high‐grade nickel and cobalt mineralisation, many of the auger holes, which started in alluvium (stream sediment), could not advance due to water influx into the holes. In those areas where auger drilling has been ineffective, further RC drilling will be required to test beneath the alluvium.
Some of the better assay results from the recent auger drilling at the Daniel’s Creek Fault Zone include:
-
5.0m @ 0.87 % nickel and 0.22% cobalt from 2.0m to 7.0m (EOH) in ITAP‐AG00128;
-
3.0m @ 0.84 % nickel and 0.21% cobalt from 1.0m to 4.0m (EOH) in ITAP‐AG00127;
-
5.0m @ 0.73 % nickel and 0.15% cobalt from 2.0m to 7.0m (EOH) in ITAP‐AG00099;
-
5.0m @ 0.70 % nickel and 0.11% cobalt from 1.0m to 6.0m (EOH) in ITAP‐AG00163;
-
4.0m @ 0.69 % nickel and 0.11% cobalt from 2.0m to 6.0m (EOH) in ITAP‐AG00096;
-
4.0m @ 0.51% nickel and 0.12% cobalt from 2.0m to 6.0m (EOH) in ITAP‐AG00100; and
-
3.0m @ 0.79 % nickel and 0.13% cobalt from 3.0m to 6.0m (EOH) in ITAP‐AG00105.
All of these intersections finished in mineralisation (see Figure 1 and attached Table 1 for a full list of auger assay results).
The results indicate that the high‐grade mineralisation does extend beneath Daniel’s Creek between the North and South zones of the Northern Target. In this area there is more than 300m of untested strike potential to be tested with further RC drilling.

Northern Target (Western Contact)
Wetlands also cover the western margins of the Northern Target (see Figures 1 and 2). The mineralisation at the Northern Target remains open to the west and south‐west along roughly 2.5km of the 3.5km strike extent of the Northern Target.
Auger drilling has been carried out along these limits and has successfully identified high‐grade nickel and cobalt mineralisation beyond the current limits of the Exploration Target. As with some of the auger drilling in the Daniel’s Creek Zone, many of the auger holes did not pass through the alluvium and, as such, will require RC drilling to fully test the extent of the mineralisation.
The following assay results are from the western contact north of Daniel’s Creek:
-
2.7m @ 1.21 % nickel and 0.07% cobalt from 2.0m to 4.7m (EOH) in ITAP‐AG00078;
-
2.6m @ 1.09 % nickel and 0.08% cobalt from 2.0m to 4.6m (EOH) in ITAP‐AG00077;
-
3.3m @ 1.28 % nickel and 0.04% cobalt from 3.0m to 6.3m (EOH) in ITAP‐AG00080;
-
1.2m @ 1.04 % nickel and 0.08% cobalt from 2.0m to 3.2m (EOH) in ITAP‐AG00074;
-
2.0m @ 1.16 % nickel and 0.05% cobalt from 1.0m to 3.0m (EOH) in ITAP‐AG00201; and
-
7.0m @ 0.94 % nickel and 0.07% cobalt from 6.0m to 13.0m (EOH) in ITAP‐AG00079.
The following assay results are from the western contact south of Daniel’s Creek:
-
4.0m @ 1.13 % nickel and 0.11% cobalt from 1.0m to 5.0m (EOH) in ITAP‐AG00139;
-
1.0m @ 1.10 % nickel and 0.08% cobalt from 4.0m to 5.0m (EOH) in ITAP‐AG00130; and
-
3.0m @ 0.67 % nickel and 0.02% cobalt from 3.0m to 6.0m (EOH) in ITAP‐AG00132.
All of the intersections reported above finished in mineralisation (see Figure 1 and attached Table 1 for a full list of auger assay results).
The result from auger hole ITAP‐AG00139 (4m at 1.13% Ni and 0.11% Co) is particularly interesting as it indicates the presence of high‐grade mineralisation at the south‐western limit of the current Exploration Target, showing that the mineralisation may trend further to the south‐west than originally thought. Additional auger drilling has been planned for this area (see Figure 1 – yellow triangles).
Northern Target (Eastern Contact)
The auger drilling beyond the current limits of the Eastern Contact has extended the high‐grade nickel‐cobalt mineralisation with ITAP‐AG00076 intersecting 4.7m @ 2.44 % nickel and 0.03% cobalt from 5.0m to the end‐of‐ hole (EOH). Further RC drilling will also be required in this area.
New North‐eastern Target
The exploration team has also identified a new target in the north‐eastern portion of the project area (see Figure 1). The mineralisation represents the tail of Vale’s neighbouring Jacarezinho Nickel Laterite Project.
Drilling at the North‐eastern Target returned multiple intersections of nickel‐cobalt laterite mineralisation. The target area is roughly 500m long and 200m wide. The best results from initial auger drilling in this area include:
-
2.0m @ 0.86 % nickel and 0.04% cobalt from 9.0m to 11.0m (EOH) in ITAP‐AG00239; and
-
1.0m @ 0.41 % nickel and 0.05% cobalt from 2.0m to 3.0m in ITAP‐AG00237.
See Figure 1 and attached Table 1 for a full list of auger assay results.

The North‐eastern Target area is partially covered by vegetation and the appropriate clearing licenses will be required to test the new target with RC drilling. An RC program has been designed for this target to be completed in the next phase of work.
Next Steps
The auger program is continuing at the Itapitanga Nickel‐Cobalt Project. In parallel, the Company has lodged the appropriate applications for RC drilling of the vegetated wetland that covers both the Daniel’s Creek Fault Zone and the Western Contact of the Northern Zone and is working with the local agencies to expedite this licence.
Once this licence is approved, the Company is positioned to be able to commence a second phase of RC drilling. Planning for this next phase of work is underway and would include brownfields exploratory drilling over the new targets identified in the latest auger program as well as a number of undercover targets following the positive results from RC drill hole ITAP‐RC‐18‐114, which intersected 30.0m @ 0.90% Ni and 0.04% Co underneath 12.0m of granite country rock.
The Phase 2 drilling program currently being planned would also involve resource definition drilling to allow for the estimation of a maiden JORC Mineral Resource estimate.

About the Itapitanga Nickel‐Cobalt Project
The Itapitanga Project covers an area of approximately 50km[2 ] and is located in the Carajás Mineral Province of northern Brazil. The Project is the southern extension of the same ultramafic‐mafic intrusive complex that hosts both the Jacaré Ni‐Co deposit and several unpublished nickel‐cobalt resources held by Vale (see Figure 3 below).
Anglo American’s neighbouring world‐class Jacaré Ni‐Co Deposit, is one of the highest large‐tonnage nickel‐cobalt grades in the world with a 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] .
The Itapitanga Project is located on farm land 50km northeast of the regional centre of São Felix de Xingu and accessible all year via unpaved road. The project is located 110km from Vale’s operating nickel mine Onça‐Puma.
Figure 3 – Location of the Itapitanga Nickel‐Cobalt Project. The regional magnetic signature (AS) is coincident with the ultramafic intrusive that hosts the nickel‐cobalt mineralisation.

APPENDIX B – TECHNICAL DETAILS OF THE ITAPITANGA NICKEL‐COBALT PROJECT, JORC CODE, 2012 EDITION – TABLE 1 SECTION 1 SAMPLING TECHNIQUES AND DATA
| Criteria | Commentary | 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. Sections are 200‐400m apart with 50‐100m 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 is placed in a plastic sample bag with a sample tag | ||
| before being sent to the laboratory. | ||
| | The first phase of RC drilling involves drill sections that are 200 or 400m. Generally there is 100m | |
| spacing between drill holes on sections. Samples are split to make 3‐5kg samples, a twin 3‐5kg sample | ||
| is kept for metallurgical testwork. The sample is placed in a plastic sample bag with a sample tag | ||
| before beingsent to the laboratory. | ||
| Drilling techniques | | Auger drilling was completed using a hand‐held auger with a 200mm auger bit. Drilling depth is |
| determined by drill refusal. | ||
| | RC drilling was completed 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. | ||
| | All holes drilled to date have been vertical. | |
| Drill sample recovery | | RC sample weights are taken for all samples and a recovery estimate is made where the sample is not |
| wet. Where the sample is wet a visual estimate of the sample recovery is made. To date the estimated | ||
| recovery is approximately 80%, which is considered acceptable for a nickel‐cobalt laterite deposit. | ||
| | 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 drillingthrough the water table or other zones of difficultground conditions. | ||
| Logging | | All outcrop and soil sample points were registered and logged in the Centaurus geological mapping |
| points database. | ||
| | 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. A hand‐held XRF is also | ||
| used to take real time geochemical readings to assist in the logging process. Logging is both qualitative | ||
| and quantitative. | ||
| | Chiptrays have been collected, photographed and stored for all drill holes to‐date. | |
| Sub‐sampling techniques | |
1m samples were taken from the cyclone and then split by rifle splitter (if dry) or manually (if wet) |
| and sample preparation | using the fish‐bone technique. Sample weight is between 3‐5kg. | |
| | QAQC: A blank sample is inserted at the start of each hole. Standards (3 different standards are used | |
| on a rotating basis) are inserted every 20 samples. Field duplicates are completed every 20 samples. | ||
| | Sample sizes are appropriate for the nature of the mineralisation. | |
| | All geological samples were received and prepared by SGS Geosol Laboratories in Parauapebas, Brazil | |
| as 0.5‐5kg samples. They were dried at 105°C until the sample was 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 50galiquots for chemical analysis. | ||
| Quality of assay data | | Chemical analysis for metal oxides is determined using XRF analysis (XRF79C). Fusion disks are made |
| and laboratory tests | with pulped sample and the addition of a borate based flux. Analysis at SGS is for a 12 element suite. | |
| LOI is determined by thermo‐gravimetric analysis at 1000°C. Fusion/XRF analysis is considered to be | ||
| an industry standard to analyse nickel‐cobalt laterite ore. | ||
| | 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 laboratories 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. |

| and assaying | Company personnel and the Competent Person before release. | |
| | All RC sampling is completed by Centaurus field staff under supervision of Centaurus geologists. | |
| Logging is entered into the Centaurus database (MS‐Access) on site. SGS Geosol send assay results as | ||
| csv files which are imported into the Centaurus database by geologists. All data is validated by | ||
| Centaurus geologists and the Exploration Manager. | ||
| | Although no RC twin holes have been completed to date good correlation has been observed between | |
| the RC drill results and the auger result. | ||
| Location of data points | | To date drill collars have been picked up using hand‐held GPS units. Drill collars and the project |
| topography will be surveyed once the first phase of drilling is complete. | ||
| | The survey grid system used is SAD‐69 22S. This is in line with Brazilian Mines Department | |
| requirements. No mapping points are reported. | ||
| Data spacing and | | Soil sampling was completed on 200‐400m line spacing with 50m between samples. |
| distribution | | Auger drilling was completed on 200‐400m line spacing with 50‐100m between holes. |
| | The first phase of RC drilling was completed primarily on 400m line spacing with 100m between drill | |
| holes. There are localised cases where the section spacing is 200m and there is 50m between holes on | ||
| section. | ||
| | No sample compositinghas been applied. | |
| Orientation of data in | | The extent and orientation of the mineralisation was interpreted based on initial field mapping, soil |
| relation to geological | sampling, auger drilling and regional geophysical interpretations. | |
| structure | | All drill holes to date are vertical and give a true width of the laterite mineralisation. |
| Sample security | | All samples were placed in plastic sample bags and then numbered. Bags are sealed and placed in |
| larger bags (10 samples per bag) and then transported to the SGS Geosol laboratory in Parauapebas, | ||
| PA. Sample request forms are sent with the samples and via email to the laboratory. Samples are | ||
| checked at the laboratory and a work order is generated by the laboratory which is checked against | ||
| the sample request. | ||
| Audits or reviews | | The Companyis not aware of anyaudit or review that has been conducted on theproject to date. |

| Geology | | The Itapitanga Project forms part of the southern extension of the ultramafic‐mafic intrusive |
| complex (2.8Ga) that intrudes the Archean Xingu basement granites in the western region of the | ||
| Carajás Mineral Province. | ||
| | Nickel‐cobalt laterite mineralisation generally occurs from surface and is associated with the | |
| ferruginous laterite of the ultramafic protore. Nickel mineralisation is associated with the saprolite | ||
| that underlies the ferruginous laterite. | ||
| Drill hole Information | | Assay results have been received for 155 RC drill holes for a total of 4,309m drilled. |
| | Refer to ASX release on 28 August 2018 for full list of significant intersections and additional RC drill | |
| hole data frompreviouslyannounced drilling. | ||
| Data aggregation methods | | Continuous sample intervals are calculated via weighted average. Significant intersections |
| considered a 0.50 % nickel or 0.08% cobalt cut‐off and 2m maximum internal waste for RC drilling | ||
| and 0.40 % nickel or 0.08% cobalt cut‐off and 2m maximum internal waste for auger drilling. | ||
| | There are three significant intersections for scandium only that considered a 20g/t scandium cut‐off | |
| and 2m maximum internal waste. ICP assay results (scandium) only received up to ITAP‐RC‐18‐084. | ||
| | Further details of the auger intersections can be found in the drill hole results of Table 1. | |
