SEPTEMBER QUARTER HIGHLIGHTS

CANDONGA IRON ORE PROJECT

  • Positive Feasibility Study completed confirming the viability of Candonga as a low capital (A$3.6 million) and low operating cash cost (A$12.5 per tonne of product) project.

  • Maiden JORC 2012 Proved and Probable DSO Ore Reserve estimate completed for the main Coruja Deposit at Candonga of 1.2Mt at an average grade of 60.5% Fe.

  • Ore Reserves will produce 0.9Mt of high grade (+63%), low impurity lump, hematitinha and sinter feed products.

  • Ore Reserve is sufficient for 3 years of operations at the planned 300,000tpa production rate with a life‐of‐mine strip ratio of 0.6:1.

  • Positive extensional drilling completed at the Coruja Deposit, with results including 22.8m grading 63.8% Fe and 14.9m grading 65.8% Fe. These will be included in subsequent resource updates to support more detailed mine planning.

  • Encouraging results received from initial drilling at the Águia target, 750m to the south‐east of Candonga, with results including 20.7m grading 46.5% Fe and 13.3m @ 48.8% Fe, supporting the potential that this area could host another small high‐grade zone of DSO mineralisation.

JAMBREIRO IRON ORE PROJECT

  • Ongoing dialogue continues with potential off‐takers for the Project.

  • Processing of further Jambreiro ore is underway at the Fundação Gorceix pilot plant facilities to produce a further high grade bulk product sample for delivery to potential offtakers for testing.

CORPORATE

  • Board restructure completed following rationalisation of the Company’s management team and workforce, both in Australia and Brazil. The changes are designed to conserve cash and are consistent with the revised timing for development of the Jambreiro Project.

CANDONGA IRON ORE PROJECT (CTM 100%)

Centaurus is fast‐tracking the development of the Candonga Project, located approximately 35km south of the Jambreiro Project. The Company’s near‐term strategy is to secure the necessary approvals and funding for Candonga and to commence operations as soon as possible to generate early cash flow.

The Candonga Project is situated in the municipality of Guanhães, 15km by road from the town centre, 35km by road from the Jambreiro Project and about 250km north‐east of the state capital, Belo Horizonte (Figure 1). The main economic base of the Guanhães community is currently agriculture and forestry, and the Candonga Project will be the first significant mining operation in the vicinity of the municipality.

The Candonga Project comprises the Coruja Deposit and the Águia Prospect.

During the Quarter, made substantial progress in advancing the Candonga Project, with the Project now development‐ready subject to the receipt of licensing and funding.

Key activities during the Quarter included the completion of a diamond drilling program designed to upgrade the existing high‐grade DSO Mineral Resource base at Candonga into the Measured and Indicated categories, delivery of a maiden JORC 2012 compliant Ore Reserve estimate for the Coruja Deposit of 1.2Mt at an average grade of 60.5% Fe and completion of a Feasibility Study.

The Feasibility Study results were announced to the market on 30 September 2014, together with the maiden Ore Reserve. The FS confirmed the viability of the Project, despite the current depressed iron ore price, paving the way for Centaurus to move ahead with its fast‐track development plans for the Project.

In‐Fill Drill Results

Early in the September Quarter, the Company completed a diamond drill program over the Coruja Deposit area. The program confirmed the presence of a near‐surface, generally flat‐lying lens of high grade itabirite that extends up to 30m from surface within a broader zone of friable Itabirite mineralisation.

Highlights of the results from this drilling program included the following continuous intersections (refer to Figure 3 for drill‐hole locations and Appendices A and B for a full list of the drill results from the Project):

The updated Mineral Resource underpins the Candonga Project Ore Reserve estimate and the DSO Feasibility Study, which were both released to the market at the end of September 2014.

Maiden Ore Reserve

The total JORC 2012 Proved and Probable DSO Ore Reserve estimate for the Candonga Project is 1.2Mt at an average grade of 60.5% Fe. The Ore Reserve is scheduled to produce 0.9Mt at an average grade of 63.5% Fe of lump, hematitinha and sinter feed product, which will provide a mine life of three years at the planned production rate of 300,000 tonnes per annum.

During the first two years of production the mining strip ratio will be an extremely low 0.25 tonnes of waste (including low grade material) for every 1 tonne of ore. The life‐of‐mine strip ratio is also very low at 0.6:1. The total material movement over the three year mine life is approximately 1.9Mt.

Mine planning optimized the recovery of higher value lump products (lump and hematitinha) from the simple dry crush and screening process as these products are in high demand in the Brazilian domestic market and deliver a solid premium over sinter feed (‐6.3mm) pricing.

The Ore Reserve estimate has been based on the Feasibility Study completed during the Quarter by Centaurus, with support from Micromine do Brasil Consultoria e Sistemas Ltda (Micromine) and other local consultants.

The Ore Reserve estimate is summarised in Table 2 below with additional technical information provided in Appendix C.

In order to optimise the production of higher value lump and hematitinha products, a simple blend strategy has been planned based on dividing the Ore Reserve into two ore categories and then blending the products at the product stockpiles. These ore categories are:

  • Direct Shipping Ore (DSO) – ore that requires no beneficiation to produce saleable lump, hematitinha or sinter feed products; 61.3% Fe cut‐off grade applied. The DSO component of the Ore Reserve estimate is 726,000 tonnes at an average grade of 64.8% Fe; and

  • Lump Blending Ore (LBO) – ore that produces lump and hematitinha products within market specifications after blending with appropriate DSO products; 45.0% Fe cut‐off grade applied. The LBO component of the Reserve estimate is 483,000 tonnes at an average grade of 53.9% Fe.

Sinter feed produced from the LBO ore is not intended to meet immediate sales specifications and will be stockpiled as “Low Grade Fines” for future processing.

Of the total saleable product, approximately half will be lump (‐31.5 + 19.0mm) and hematitinha (‐19.0 + 6.3mm) at an average grade of 62.8% Fe. The balance of production will be a high quality sinter feed product with an average grade of 64.0% Fe.

Candonga Feasibility Study

The Candonga Feasibility Study, which was completed during the Quarter, confirms the technical and financial viability of a 300,000tpa project producing a suite of high‐grade Direct Ship Ore (DSO) products to the local steel and pig iron industries. Key highlights of the Feasibility Study include low forecast mine gate cash operating costs (C1 + Royalties) of A$14.9/tonne and a very low pre‐production capital cost of A$3.6 million.

The key financial parameters of the project include forecast revenues of A$36.5 million and EBITDA of A$23.1 million over a 3‐year period (using an estimated mine gate life‐of‐mine domestic sale price of A$41/tonne).

The strong economics – generated from the modest capital investment – will enable Centaurus to establish a solid cash‐flow business in Brazil. This will allow the Company to leverage its knowledge of the iron ore sector in Brazil to expand its production base through the development of other similar low‐cost DSO opportunities which are currently being assessed or alternatively, its fully‐licensed Jambreiro Project.

The Company’s Project Implementation Plan has been built around completing the mining contract in Q4 2014 and being in a position to commence site development activities in February 2015. On‐site development is planned to take around two months, enabling the commencement of production in April 2015 following the end of the 2014/2015 wet season in south‐east Brazil.

Both the environmental and mining approvals processes are well advanced and on schedule. The Company lodged its combined Preliminary and Installation Licence (LP/LI) application in May 2014 and its trial mining licence in April 2014. Final approvals are expected to be received by Q1 2015.

The Study was prepared in conjunction with Micromine do Brasil Consultoria e Sistemas Ltda (Micromine), who completed the estimation of the Mineral Resources and Ore Reserves, mine planning and sequencing, overall mine design and assessment of the required mining fleet.

Key Feasibility Study Outcomes and Assumptions

The key financial outcomes of the FS are set out in Table 4 below with key assumptions summarised in Table 5.

Capital & Operating Costs

The total pre‐production capital costs for the Project have been estimated at a very modest A$3.6 million, which equates to a very attractive A$12 per tonne of annual production. The low capital costs are a function of the fact that the Company will mine high grade ore and simply process the ore through a dry crushing and screening plant to extract the various lump, hematitinha and sinter feed products.

The C1 operating cash costs over the life‐of‐mine (LOM) at the mine gate are a very attractive A$12.5 per wet tonne of product. The Company will use a mining contractor for the mining operations. Detailed quotes have been received from a number of mining contract groups and these have been used to generate the mining costs of the Project. There will be no drill and blast activities required on site.

Domestic Sales Market

Hematitinha is predominantly sold to domestic pig iron producers who use the material in their mini blast furnaces (MBF). Pig iron producers have limited cost effective means of substituting out hematitinha for sinter or pellets in the MBF and as such there is a true domestic market pricing regime for hematitinha.

Lump and sinter feed is predominantly sold to the integrated steel mills but could also be sold to other mining groups as a quality enhancer for their own product mix. The pricing for lump and sinter feed is expected to be a function of the prevailing international export markets, overall product quality and a logistic cost net‐back.

For the purpose of the FS, the Company used an average FOB mine gate price of A$41 per wet tonne over the life of the Project. CRU Strategies provided an independent domestic market review which was used by the Company to assist in the assessment of product pricing. The Company believes that this pricing profile is conservative even after allowing for the current low price of iron ore in the global market.

Project Concept & Layout

The Candonga Project has the following major components:

  • One open pit (Coruja) operated on a contract mining basis;

  • Two waste dumps and a top soil dump;

  • Crushing and screening plant capable of producing 300ktpa of lump, hematitinha and sinter feed product; and

  • Infrastructure facilities (including water supply, workshop, laboratory, weighbridge, fuel storage, office, safety and occupational health facilities).

Project Implementation Plan

The Project site implementation program will start upon the approval of the Installation Licence (LI), which is expected before February 2015. Plant installation and mine preparation will then commence immediately, with commissioning planned for March 2015 and first production planned for April 2015.

The dry crushing and screening plant contemplated for the Candonga Project is “off‐the‐shelf” equipment in Brazil and procurement lead‐times are short. The equipment can be easily transported to site and the time from order to installation is expected to be approximately two months. The Company will engage the operations team at the commencement of the plant installation. The implementation team will comprise key Centaurus personnel and the mining contractor.

Environmental Approvals and Project Development Timetable

The Company lodged a combined Preliminary Licence/Installation Licence application (LP/LI) in May 2014 and is now awaiting approval. The Company expects the relevant approval to be received before February 2015. The Company is not expecting any issues with the approval process as the area of the Project is pasture with no native vegetation removal required.

Furthermore, the strong social and economic benefits that will flow to the region from the development of the Candonga Project have also helped create a very positive relationship with local communities and stakeholders.

Exploration Drill Results

The Company has received the final batch of assays from the recent diamond drill program at the Candonga Project. The results come from the Coruja Deposit resource extension drilling and drilling of the Águia Prospect, located 750m south‐east of the Coruja Deposit.

Coruja Deposit Extension Drilling

Diamond drill holes were completed along strike at the Coruja Deposit, to the northwest of a drainage that was previously understood to be the western limit of the DSO mineralisation. A drill section located 70m northwest of the drainage successfully intersected high grade itabirite mineralisation in drill hole CDG‐DD‐ 14‐00023 (14.9m at 65.8% Fe) and CDG‐DD‐14‐00024 (7.3m at 62.0% Fe).

The final hole of the drill program (CDG‐DD‐14‐00026) was drilled a further 30m along strike and intersected mineralisation at 45m depth. No further drilling was carried out due to the likely high strip ratio that would be associated with the mineralisation identified on this section.

Down‐hole results are shown on the map in Figure 3 and the Table in Appendix A. Highlights of the previously unreleased results include the following continuous intersections:

  • 22.8m @ 63.8% Fe, 6.2% SiO2, 1.1% Al2O3 and 0.04% P in CDG‐DD‐14‐00019 from 7.3m;

  • 17.0m @ 62.5% Fe, 5.2% SiO2, 3.1% Al2O3 and 0.02% P in CDG‐DD‐14‐00022 from 3.0m;

  • 14.9m @ 65.8% Fe, 2.6% SiO2, 1.4% Al2O3 and 0.04% P in CDG‐DD‐14‐00023 from 20.7m; and

  • 7.3m @ 62.0% Fe, 8.8% SiO2, 0.5% Al2O3 and 0.03% P in CDG‐DD‐14‐00024 from 23.0m.

The above assay results from the Coruja Deposit were not included in the updated Mineral Resource estimate referred to above. The results will be used to complement the geological interpretation and eventually update the block model to support more detailed mine planning.

Águia Prospect Drilling

Two exploration drill holes were completed on the Águia target, which is located 750m to the south‐east of Candonga (see Figure 3). The drilling intersected 20.7m of itabirite mineralisation grading 46.5% Fe (including 3.4m at 63.8% Fe) in hole CDG‐DD‐14‐00020 and 13.3m of itabirite mineralisation grading 48.8% Fe (including 3.2m at 66.6% Fe).

The Águia magnetic anomaly is of similar scale to that of the Coruja Deposit and sits on the ridge of a hill demarcated by high grade itabirite blocks and rich magnetic soils. To date native vegetation has hindered access to preferred drilling locations. The Company is in the process of securing the necessary licenses to conduct additional drilling at this target.

The information gathered from drilling at the Coruja Deposit gives the Company confidence that the Águia prospect could host another small high‐grade zone of DSO mineralisation.

JAMBREIRO IRON ORE PROJECT (CTM 100%)

Jambreiro remains one of the few fully permitted, development‐ready greenfields iron ore projects in Brazil. Discussions with a number of parties in relation to off‐take and other potential transactions progressed during the Quarter.

In order to advance off‐take considerations and allow for an assessment of the high quality of Jambreiro ore in the sintering process, the Company was requested to provide a further bulk sample of Jambreiro product for testing with a potential off‐taker. Accordingly, the Company made the necessary arrangements to extract further ore at Jambreiro from trenches and have it processed at the Fundação Gorceix pilot plant facilities. Upon completion of the processing the product sample can be delivered to the potential off‐taker.

APPENDIX C – JORC Code, 2012 Edition – Table 3 Compliance Statement for Candonga Project

SECTION 1 ‐ SAMPLING TECHNIQUES AND DATA

(Criteria in this section apply to all succeeding sections).

Criteria Commentary
Sampling
techniques
 All trenches in the 2013 program were cut down to 2.2m. Continuous cut channels were sampled on
2m intervals or to lithological contacts. The 3‐5kg samples were split and pulverised to ±50g
samples for XRF and titration analysis.
 RC samples were taken at 1m intervals from which 3‐5kg samples were split, prepared and analysed
as above.
 Diamond samples were taken at maximum 1.4m intervals or to lithological contacts no less than
0.3m from which ¼ core (3‐5kg) was sampled, prepared and analysed as above.
 The Candonga Project has a regular drill hole spacing of around 40mx25m over the high grade
itabirite zone. Drilling on the other areas of the Project are irregular.
 Field duplicate samples were taken at a set frequency of one every 20 samples (5% of total samples)
from the splitter to monitor sample representivity.
 All of the data used for the resource estimation is based on the logging and sampling of historical
trenches, RC and diamond core drilling.
 Classification testwork samples from drill core were continuous with the minimum sample interval
being 1.0m. A ¼ core sample was taken and the minimum sample weight was 3.5kg with maximum
sample weight being 25kg. All sample intervals are described in the ASX announcement dated 18
August 2014.
 For classification bulk samples, a small excavator was used to target samples of specific lithologies
(in situ itabirite and mineralised colluvium). Sample weights were between 250‐500kg
Drilling
techniques
 Historically three diamond holes (HQ) were drilled by Cenibra for a total of 95m in 2007. These
holes are not used in the resource estimation.
 Centaurus completed 1 diamond drill hole (HQ) for a total of 88m in 2010.
 RC drilling employed a 5.5” face hammer. Centaurus completed 27 RC holes for a total of 1,654m in
2010 and 2013.
 Centaurus has completed a further 25 diamond drill holes (HQ) for a total of 784m in 2014 of which
17 holes for a total of 484m were used in the Mineral Resource estimate reported on 1 September
2014.
 Hole depths range from 12 to 95m.
Drill sample
recovery
 For diamond drilling, core recoveries were logged and recorded in the database for all Centaurus
diamond holes. Overall recoveries are >85%. There were localised core loss issues due to changes in
material type. Drilling was controlled to maximize core recovery.
 For RC drilling, geologists or field assistants recorded sample weights and calculated sample
recovery during drilling. No significant issues were detected.
 To ensure adequate sample recovery and representivity a Centaurus geologist or field technician
was present during drilling and monitored the sampling process.
 No relationship between sample recovery and grade has been demonstrated. No bias to material
size has been demonstrated.
Logging  All trenches and drill holes have been logged geologically and geotechnically to a level of detail
appropriate to support the Mineral Resource estimate as well as metallurgical and mining study
support for iron ore.
 Logging for both forms of drilling is qualitative and quantitative in nature.
 All Centaurus trenches, RC chip trays and diamond core have been photographed. Historical drilling
was not photographed.
 The total length of drilling used in the resource estimate is 2,226m. 100% has been logged. The total
length of trenches is 444m. 100% has been logged.

Criteria Commentary
Sub‐sampling
techniques
and sample
preparation
 Diamond Core (HQ) was cut with a specialized sampling tool where friable or using a core saw
where compact. A quarter core was sampled.
 RC samples were collected on 1m down hole intervals reduced using a 3‐tier riffle splitter reducing
the sample size to 3‐5kg. Sample weight/split analysis shows that on average a 12.5% split ratio was
achieved.
 The majority of mineralised samples from RC drilling were dry.
 All samples were received and prepared by ALS, SGS or Intertek Labs in Belo Horizonte, Brazil as 3‐
5kg samples. They were dried at 105°C until the sample was completely dry (6‐12hrs), crushed to
90% passing 2mm and reduced to 500g via a Jones riffle splitter. The 500g samples were pulverised
to 95% passing 104µm and split further to 50g aliquots for chemical analysis.
 Field control sample insertion included field duplicates taken every 25 samples. Results from the
duplicate samples show the data has an acceptable precision, indicating that the sampling
technique is appropriate for the deposit.
 The sample size is considered to be appropriate to correctly represent the mineralisation as well as
the thickness and consistency of the mineralised intersections.
 Classification samples for the Candonga DSO Project have been taken from the first 17 holes of the
2014 diamond program.
 All metallurgical samples were received and prepared at the Centaurus SPF. The samples were
received naturally dry. After homogenization the sample was crushed to ‐32mm and water was
added to simulate 4% and 7% natural moisture.
 Dry sieve analysis was completed using a screening plant for the following size fractions: ‐31.5mm, ‐
19.0mm and, ‐6.3mm.
 The product samples were split to 1kg then pulverised and split further to a 100g aliquots that were
sent to SGS Geosol for chemical analysis.
Quality of
assay data and
laboratory
tests
 All chemical analysis was completed at ALS, SGS or Intertek Labs. Laboratory duplicates were
completed every 10‐20 samples and standards were completed every 20‐25 samples dependent on
the laboratory.
 Laboratory control sample insertion included blank samples at the start of every new hole then
every 50 samples. Standard samples (CRMs from Geostats Australia) are inserted every 20 samples.
A number of different standards at a range of grades are used to monitor analytical precision of the
assay results. Field duplicates were inserted every 25 samples.
 Metal Oxide is determined using XRF analysis. Analysis at ALS was for a 24 element suite while at
Intertek analysis was for 11 elements. FeO is determined using Titration and LOI using Loss
Determination by Thermogravimetric analysis.
 Laboratory procedures are in line with industry standards and are appropriate for iron ore.
 Acceptable levels of precision have been achieved with all standard assays reporting within 2
standard deviations of the certified mean grade for the main elements of interest.
 The ALS, SGS and Intertek labs insert their own standards at set frequencies and monitor the
precision of the XRF analysis. These results also reported well within the specified 2 standard
deviations of the mean grades for all main elements. Additionally the labs performed 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.
 Analysis of field duplicates and lab pulp duplicates have returned an average correlation coefficient
of over 0.96 confirming that the precision of the samples is within acceptable limits.
 Centaurus sends a selection of pulps to umpire laboratories (Acme) for independent verification. To
date comparison of results between laboratories did not reveal any issues and analytical precision
was considered acceptable.
 CentaurusQAQCprocedures and results are to industrystandard and are of acceptablequality.

Criteria Commentary
Verification of
sampling and
assaying
 All significant intersections are verified by alternative Company personnel before release. As part of
Resource estimation processes, drill hole data was independently reviewed by BNA Micromine.
 No twin holes have been completed to date.
 All primary data is stored in the Centaurus Exploration office (Guanhães, Brazil). All data is entered
into a Micromine Geobank database which is administrated by a database geologist.
 No adjustments were made to the assay data apart from resetting the below detection level values
to half of the detection limit.
Location of
data points
 The survey grid system used is SAD‐69 23S. This is in line with Brazilian Mines Department
requirements. All survey collars and trenches were surveyed using a total station. There were no
down hole surveys completed.
 Complete topographical survey pickup of the area was done using a total station with pickup
completed on 10x10m spacing.
Data spacing
and
distribution
 Drill sections run perpendicular to the high grade itabirite mineralisation at spacing between 30‐
40m. Drill spacing away from the high grade zone is irregular. Drill holes on section are generally 25‐
30m apart. Due to local topographical constraints the spacing is sometimes not achievable.
 The data spacing and distribution is considered adequate to establish the degree of geological and
grade continuity appropriate for the Mineral Resource estimation and classifications applied under
the JORC 2012 code.
 No sample compositinghas been applied.
Orientation of
data in
relation to
geological
structure
 The orientation of the mineralisation is understood and drill holes were designed to intersect the
mineralisation at an appropriate angle. This is demonstrated in the geological cross‐sections (see
Figures 4‐5).
 All significant intersections have been reported as downhole widths and not true widths.
 The trenches by nature are oblique to the mineralisation angle and as a result return accentuated
mineralised interval.
 No drilling orientation and sampling bias has been recognized at this time and is not considered to
have introduced a samplingbias.
Sample
security
 All samples are placed in pre‐numbered plastic samples bags and then a sample ticket is placed
within the bag as a check. Bags are sealed and placed in larger bags (10 samples per bag) and then
transported by courier to ALS or Intertek labs in Belo Horizonte. Sample request forms are sent with
the samples and via email to the labs. Samples are checked at the lab and a work order is generated
by the lab which is checked against the sample request.
 All remnant diamond core, RC chip trays, sample rejects and pulps are stored at the Guanhães
technical office.
Audits or
reviews
 As part of the Resource estimation process drill hole data was independently reviewed by
Volodymyr Myadzel the BNA Micromine Senior Resource Geologist and project Competent Person.
The report finds the sample techniques and data collection and management to be in line with
current industrystandards.

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 Candonga Project tenement (DNPM 831.629/2004) is 100% owned by Centaurus.
 The tenement is part of the Cenibra‐Centaurus Agreement. Centaurus will pay a vendor royalty of
0.85% of gross revenue on any product sold from the tenement.
 All mining projects in Brazil are subject to the CFEM royalty, a government royalty of 2% of revenue
(less taxes and logistics costs).
 Landowner royalty is 50% of CFEM royalty.
 The Project is not located within national or state wilderness or historical parks.
 The Final Exploration Report was submitted on 27 November 2013. An application for a Trial Mining
License was submitted on 11 April 2014. The licence allows for the mining and dry processing of
300ktpa of ROMper license.
Exploration
done by other
parties
 Cenibra conducted geological mapping and a small diamond drill program in 2007 to satisfy Brazilian
Mine Department requirements. This work is not incorporated into the Resource.
Geology  The Candonga Project is located within the Guanhães Group (Lower Proterozoic) of the Mantiqueira
Complex. The region is dominated by structurally complex meta‐volcanic and meta‐sedimentary
sequences with duplex fault systems and folding ranging from micro folding in outcrop to large scale
regional deformation.
 The Itabirite units are part of an iron formation including ferruginous quartzites, quartz mica schists
and amphibolites within a metasedimentry sequence. This sequence is emplaced in regional gneissic
basement.
 The Itabirite mineralisation comprises concentrations of medium ‐ coarse grained friable and
compact material that have undergone iron enrichment. The mineralisation is composed of quartz,
hematite, magnetite, goethite, limonite, with minor amphibole (grunerite), Mica (muscovite) and
clay minerals.
 Itabirite thicknesses vary from 5m to up to 40m generally dipping 30‐55° to the N‐NE. The combined
strike length of the mapped mineralisation is around 1,500m. Itabirite has been intersected at
depths up to 88m with friable itabirite intersected up to 60m.
 There are localised occurrences of high grade itabirite or magnetite lenses (up to 30m thick)
associated with hydrothermal enrichment alongfold axis and faultplanes.
Drill hole
Information
 At the date of announcement a total of 56 holes for 2,621m have been completed by Centaurus on
the Candonga Project including 29 diamond holes for a total of 967m and 27 RC holes for a total of
1,654m. From the current drilling 17 holes (484m) are included in the resource estimate. Diamond
holes drilled by Cenibra in 2007 are not included in the resource due to low confidence in analysis.
 Refer to ASX Announcement on 1 September 2014 for full details of drill hole results.
Data
aggregation
methods
 Continuous sample intervals are calculated via weighted average using a 20% Fe cut‐off grade with
3 metre minimum mining widths.
 High grade intervals within a continuous sample interval may be reported inclusive. (For example:
CDG‐RC‐13‐0008 37m @ 56.5% Fe, including 20m @ 63.4% Fe)
 No metal equivalents are reported.
Relationship
between
mineralisation
widths and
intercept
lengths
 The orientation of the mineralisation is well understood and drill holes were designed to intersect
the mineralisation at an appropriate angle representing the true widths. Where the true width is
not intersected it is stated and also demonstrated in cross sectional diagrams.
 The trenches by nature are oblique to the mineralisation angle and as a result return accentuated
mineralised interval.

SECTION 3 ‐ ESTIMATION AND REPORTING OF MINERAL RESOURCES

(Criteria listed in Section 1, and where relevant in Section 2, also apply to this section).

Criteria Commentary
Database
integrity
 All data is entered into excel data sheets and imported into a Micromine Geobank database.
Project geologists validate the data entry.
 Assay files are sent electronically from the labs. These files are imported directly into Geobank by
the database geologist. The database geologist is responsible for up‐dating the database and
generation of validation reports.
 The independent resource geologist responsible for the Resource estimation ran additional
validation checks on the database before completing the estimation. There were no critical
database issues at the time of the final Resource estimation.
Site visits  The Competent Person for this report, Volodymyr Myadzel (Senior Resource Geologist) for
Micromine Brazil visited the site in December 2010 to complete an external audit of Centaurus’
drilling, sampling, QAQC, and logging procedures. No significant issues were revealed during the
audit that would be material to the outcomespresented in this Resource estimate.
Dimensions  With the combination of the Coruja, Aguia and other minor targets, the Candonga Resource has
dimensions of approximately 1,500m of total strike length. The ore body outcrops in most places
with a localized thin colluvial cover in places and generally open at depth with the deepest
mineralisation being intersected at 88m depth. The itabirite mineralisation is between 10‐40m
thick with the average thickness in the main deposit (Coruja) being around 30m.
 Block model extends from 721516mE to 723231mE and 7911183mN to 7912494mN and elevation
from 740mRL to 986mRL(surface).
Moisture  Tonnage is estimated on an in situ basis.
 Moisture measurements were completed as part of the detailed process test work sample regime.
An in situ moisture content of 6% was determined.
 Due to the significant topographical relief across the resource area the water table depth is quite
variable but on average sits 40m below the surface. The DSO component of the resource is located
100% above the water table.
Geological
interpretation
 There is good confidence in the geological interpretation of the central zone of the mineral
deposit. In this zone the high grade itabirite lens which is hosted in a broader itabirite zone is
consistent in grade and geometry both on section and along strike. Further work needs to be
carried out on distal zones to improve understanding. These zones are generally classified in the
Inferred Resource category.
 Surface and trench mapping as well as the ground magnetics geophysics were used for the
interpretation of mineralisation and stratigraphy where there was no drill hole support.
 Lithological domaining of the itabirite mineralisation was completed using geological logging with
the aid of geochemical analysis. The four domains reported are mineralised colluvium, high grade
itabirite, friable itabirite and compact itabirite. These domains are important in the building of the
geo‐metallurgical model and determination of lump‐fines splits and product grain size
distributions.
 Fe grades within the high grade itabirite lens are consistent; the lens contacts are sharp and in
general hosted within the larger friable itabirite zone. The northern limit of the high grade lens
and itabirite zone is truncated by an east‐west orientated sub‐vertical thrust fault.
 The Fe grade within the itabirite reduces slightly with depth due to the effect of supergene
enrichment near surface.
 The interpretation of the friable and compact boundaries was derived primarily from a hardness
scale with support from geochemical analysis where appropriate.
 Centaurus Project Geologists were responsible for all stratigraphic, structural and mineralisation
wireframe interpretations. They were then passed to the independent resource geologist
(Competent Person)to review andgenerate the block model.

Page 20

AUSTRALIAN SECURITIES EXCHANGE ANNOUNCEMENT

Criteria Commentary
Estimation
and modelling
techniques
 Itabirite mineralisation was domained according to hardness (Friable and Compact) and
mineralisation style (high grade or friable). Mineralised colluvium was domained separately and is
considered friable. Each geological unit was domained and estimated separately using hard
boundaries. Mineralisation was divided into eight domains.
 The interpretation was developed off vertical sections. Geological data was extrapolated to half
the distance between the vertical sections (30m) and 100m in depth from the deepest drill hole.
3D wireframes were built using Micromine 14.0.6 software. From the wireframes a block model
was built and interpolated.
 Inverse Distance Weighting (IDW2) was used to estimate a standard suite of 12 elements (Fe, SiO2,
Al2O3, P, Mn, TiO2, CaO, MgO, K2O, Na2O, Cr2O3and FeO) as well as LOI.
 Parent block size is X=25m, Y=25m and Z=10m with sub block size of X=2.5m, Y=2.5m and Z=2.5 m.
Average distance of sample spacing for Measured and Indicated is 45m and the search ellipse
longest axis is 50m. Search directions and ranges are domain specific and are determined from the
structural positioning of the ore body.
 All block estimates are based on interpolation into parent block volumes.
 The parent block and sub block height of 10m and 2.5m respectively was assumed based on
expected bench and flitch heights in waste and ore.
 The Mineral Resource estimate does not include any form of dilution, apart from internal waste
which could not be separated out.
 No assumptions regarding correlation between variables has been made, however, it is observed
that there are direct inverse relationships between Fe and SiO2.
 The itabirite mineralisation has clear lithological boundaries and has a Gaussian distribution so top
cuts are not applied. A lower cut‐off of 20% Fe was applied for the friable and compact itabirite
mineralisation as that appears to be the natural cut off.
 Standard model and estimation validation was completed using standard visual and statistical
methods. Visual comparisons of composite drill data with block data were completed, all with
suitable results. Visual validation of grade trends was carried out. No mining has taken place and
as such no reconciliation data is available.
Cut‐off
parameters
 A cut‐off of 55% Fe was applied to the high grade itabirite to achieve an average resource grade
similar to the average grade of the process testwork samples. A cut‐off of 50% Fe was applied to
the mineralised colluvium to achieve an average resource grade similar to the average grade of
the process testwork samples. Lower cut‐off grades than these make a minor difference to
average resource grade and volumes, as demonstrated in the grade‐tonnage curves below.
 The cut‐off grade for the itabirite mineralisation is set at >20% Fe, which appears to be a natural
grade boundary between itabirite and ferruginous quartzite. Additional process test work carried
out on <20% Fe material demonstrates it is up‐gradable to saleable product but at low mass
recoveries.
 No cut‐offgrades were applied on other contaminant elements.
Mining factors
or
assumptions
 Mining is assumed to be carried out via open pit method using conventional backhoe excavator
methods with ore and waste being mined on 5‐10m benches with 2.5m flitches. Haulage distance
will be relatively short, less than 500m. Small off‐road trucks of 25‐35t will be used. This is a
common mining fleet configuration in Brazil.
 No drill and blast will be required in the highgrade itabirite mineralised zone.

Page 21

AUSTRALIAN SECURITIES EXCHANGE ANNOUNCEMENT

==> picture [55 x 30] intentionally omitted <==

Criteria Commentary
Mining factors
or
assumptions
 Due to the visual nature of the ore to waste contacts a dilution factor of 3% and a mine recovery
of 98% was applied in the Ore Reserve estimation. These are in line with industry standards for
itabirite ore in Brazil.
Metallurgical
factors or
assumptions
 The focus of the Candonga Project will be the DSO mineralisation (high grade itabirite and
mineralised colluvium). This material will require dry crush and screen process to classify three
product types: lump (+19.0mm), hematitinha (‐19.0mm+6.3mm) and sinter feed (‐6.3mm).
 Product sizing classification results from diamond drilling and bulk trench sampling have
demonstrated that the DSO mineralisation at Candonga can deliver 25‐40% of the mineralisation
as a lump and hematitinha product with an average grade of +64% Fe. The remaining DSO
material is classified as a sinter feed product with an average iron grade of +64% Fe.
 Refer to ASX announcements on 18 August 2014 and 31 March 2014 for full details of the relevant
classification test work.
 The resource also includes friable itabirite. This material is lower grade and as such to produce a
saleable iron ore concentrate the ore mustpass through a number ofprocess stages.
Environmental
factors or
assumptions
 Both the mine waste and the plant rejects have been studied for potential acid production and
both were found to be inert.
 The Environmental Licence Application, known as the RCA/PCA, was lodged with the State
Environmental Authority (Supram)in May2014.
Bulk density  Wet bulk density measurements were completed via two methods: dill core dimensional
calculation (101) and water displacement (38). Measurements were taken every 5m in the
mineralisation and every 10m in waste. Dimensional calculation was completed for friable
material using a 20cm steel mould cutting the whole core which was then weighed. Water
displacement was carried out on 10‐20cm whole core compact samples.
 The resulting wet bulk density for the mineralised zones was 2.55t/m3for mineralised colluvium,
2.8t/m3for high grade itabirite, 2.5t/m3for friable itabirite and 3.0t/m3for compact itabirite.
 The results are considered to be conservative when benchmarked against similar high grade
itabirite deposits in the IronQuadrangle,Brazil.
Classification  Resources have been classified by the independent Competent Person in accordance with the
JORC Code 2012 Edition.
 Mineral Resources have been classified by the Competent Person in Measured, Indicated and
Inferred categories based on diamond and RC drill hole spacing (30mx30m), geological
interpretation confidence, grade continuity, QAQC and geological data confidence.
 Mineral Resource classification has appropriately taken into account the data spacing, distribution,
continuity, reliability, quality and quantity of data.
 The input data is comprehensive in its coverage of the mineralisation and does not misrepresent
in‐situ mineralisation.
 The definition of mineralised zones is based on a high level of geological understanding producing
a robust model of mineralised domains.
 The results of the validation of the block model show good correlation of the input data to the
estimated grades.
 The geological model and Mineral Resource estimation appropriately reflects the Competent
Person’s view of the deposit and appropriate account has been taken of all relevant factors.
Audits or
reviews
 As part of the Resource estimation process the geological procedures and data were internally
reviewed by Micromine, the Company responsible for the estimate. The report finds the sample
techniques and data collection and management to be in line with current industrystandards.
Discussion of
relative
accuracy/
confidence
 The confidence in this Resource estimate has been deemed appropriate for medium to long term
planning and mine design. It is not sufficient for shorter term planning and mine scheduling.
 The Candonga Resource estimate is sufficient for Feasibility level study purposes. This statement
relates to global estimates of tonnage and grade.
 Operational management of the mine geology and engineering will be important in the control of
the local variability and consequently the short term mine planning.
 There has been noproduction from the Candonga Project.

SECTION 4 ‐ ESTIMATION AND REPORTING OF ORE RESERVES

(Criteria listed in section 1, and where relevant in sections 2 and 3, also apply to this section.)

Criteria Commentary
Mineral
Resource
estimate for
conversion to
Ore Reserves
 The Mineral Resource estimate on which this Ore Reserve estimate has been based was prepared
by Volodymyr Myadzel (Senior Resource Geologist) for Micromine do Brasil Consultoria e
Sistemas Ltda. Refer to ASX announcement on 1 September 2014 for full details of the Mineral
Resource estimate.
 The Mineral Resource estimates are not in addition to the Ore Reserve estimate. The Ore Reserve
estimate is a sub‐set of the Mineral Resource estimate.
Site visits  The Competent Person is Mr Beck Nader, Director of Micromine do Brasil Consultoria e Sistemas
Ltda.
 No site visit was undertaken as presently there are no existing mine workings to examine. Mr
Nader relied on observations made byMr Myadzel who visited the site in December 2010.
Study status  A Feasibility Study has been completed by Centaurus and independent engineers (Micromine).
Refer to ASX announcement on 30 September 2014 for full details of the FeasibilityStudyresults.
Cut‐off
parameters
 The cut‐off grade was selected primarily based on marketing criteria:

For the DSO (Direct Shipping Ore) ore feed a cut off of 61.3% Fe was used to meet the Sinter
Feed product specification limit of 64% Fe,

For the LBO (Lump Blending Ore) ore feed a cut off of 45.0% Fe was used to meet the Lump
and Hematitinha product specification limit of 62% Fe once blended with the DSO product,
 Itabirite material with cut‐off above 20% Fe will be stockpiled as a low grade product (ie.
mineralised waste).
Mining factors
or assumptions
 The resource was optimised using Micromine optimising software.
 Only Measured and Indicated Resource categories were used in the optimisation process.
 The resource will be mined using traditional open pit mining methods. There are no pre‐strip
requirements and site access preparations are minimal and will be carried out by the mining
contractor.
 The overall average slope angle used for the optimisation was 42 degrees. These angles are
conservative and based on a study by geotechnical specialists Itaaçu Geologia e Engenharia Ltda.
 A project grade control management plan will be implemented by the grade control
geologist/engineer. This will include blending from the material from the pit/ROM to the crusher
as well as the blending of products. Grade control sampling will be conducted via trench face and
stockpile sampling. There is no pre‐production grade control drilling planned.
 Ore Reserve tables are stated in wet metric tonnes (wmt). The moisture has been estimated at
6%.
 A mining dilution factor of 3% has been applied for the deposit. The ore contacts are sharp and
visual and the small mining equipment will allow for selective mining.
 A mining recovery factor of 98% has been utilised. Similarly to mine dilution, the configuration of
the deposit and the selected mining equipment will allow good mining recoveries to be achieved.
 A minimum mining face width of 20 metres has been used for the design of the scheduled pits.
This is a safe mining width for the size of the proposed equipment.
 Inferred Mineral resources have not been used in the pit optimisation and pit design. All in pit
Inferred Mineral resources have been reported to low grade waste.
 Infrastructure requirements for the selected mining method will include waste dumps, stockpile
areas, haul roads, workshops, fuel storage, water catchment, weighbridge, office laboratory and
amenities.
Metallurgical
factors or
assumptions
 Centaurus proposes to crush and screen ore to three products: lump (‐31.5 + 19.0 mm),
hematitinha (‐19.0 + 6.3 mm) and sinter feed (‐6.3mm).
 The process of dry crush and screen of high grade itabirite ore in the Brazilian mining industry is
common well tested technology.
 Centaurus completed screening tests to simulate the proposed dry beneficiation on 6 bulk trench
samples and 57 diamond core samples. Samples tested are representative both spatially and of
the different ore lithologies.

Criteria Commentary
Metallurgical
factors or
assumptions
 A weighted average product split was determined for each lithology and then applied to the mine
sequencing to determine the final product masses.
 To determine the in situ cut‐off grade between ore types, a product regression formula for each
of the three product types was implemented. The formula was derived from results of the 57 test
work samples completed and demonstrates that there is an average increase in Fe grade for
Lump and Hematitinha and a decrease in Fe grade for Sinter Feed. The opposite is observed for
SiO2and Al2O3. No change is observed in P.
 The Candonga ore is high grade itabirite composed primarily of iron oxides (hematite and
magnetite). The market specifications for these ore types are variable for each product type. The
Candongaproduct comfortablymeets the Brazilian domestic market specifications.
Environmental  In May 2014, Centaurus lodged an environmental licence called a RCA/PCA with the State
Environmental Authority (Supram). This will allow 1.5Mtpa of dry processing. Supram technicians
conducted the initial site inspection on 26 August 2014 and no issues of note were raised during
the visit. Approval of the licence is expected inQ1 2015.
Infrastructure  The Candonga Project is located 15km from sealed highways and 110‐350 km from potential
customers (integrated steel mills and pig iron producers);
 Power for the proposed plant will be provided by diesel motors and a diesel storage facility will
feed the mining fleet. The office and amenities will be connected to grid power. Water
catchment is readily available in the project area.
 Theproject is located 15km from the regional cityof Guanhães which has apopulation of 50,000.
Costs  Process plant and other capital costs were developed by Centaurus using supplier information.
The FS estimated capital costs for the Project are shown in the Table below.

Costs  All iron ore projects in Brazil are subject to the CFEM royalty, a government royalty of 2% of
revenue (less taxes and logistics costs).
 A State levy known as the TFRM fee will be payable at a rate of approximately A$1.28 per tonne
of product sold.
Revenue factors  The average FOB price (across all product types) used in the Feasibility Study was A$41/wmt.
 Given the short life of the Project foreign exchange assumptions are fixed over the period of the
mine life. Forecasts of AUD/USD ‐ 0.89 and AUD/BRL ‐ 2.05 have been used.
 Centaurus engaged CRU for product pricing guidance. Pricing was further benchmarked against
current operations. Pricing is specific to product type and quality.
 The Micromine optimisation used a conservative pit that utilized an Fe price 55% of the Project
pricingassumption.
Market
assessment
 Centaurus engaged CRU for marketing guidance. Additionally Centaurus has been in negotiations
with integrated steel mills for the off take of Jambreiro and Candonga products. Pig iron
producers have shown interest in lump products. They are dependent on hematitinha supply as
they have limited economic means of substitution for sinter or high cost pellets.
 Approximately half of the annual Candonga production will be lump/hematitinha (+62% Fe) with
the balance beinga highgrade(+64% Fe)sinter feedproduct.
Economic  The followingsets out the high level economics of the Project

 The 2 key factors with the greatest impact on Project economics are product prices and exchange
rates.
Social  Centaurus maintains strong working relationships with all stakeholders in the vicinity of the
Project, including the landowners in the region.
 The Company has been operating in the region since 2010 and has established a permanent field
office in the cityof Guanhães,15km from the Project.
Other  The water catchment area is limited.
 The area has no record history of earthquakes or natural disasters.
 The project is planned to start on a trial mining licence that allows for mining of 300,000tpa of ore
per licence. The application was lodged with the DNPM on 11 April 2014. The DNPM technical site
visit was conducted on 16 September 2014. Centaurus expects the technical approval of the GU
before November 2014. In parallel the Company will apply for a full mining licence expected to be
granted in Q3 2015. There will be no additional environmental licence required for the full Mining
Licence.
 The Company has advanced the environmental licensing process for Candonga with the State
Environmental Authority (Supram) by lodging the main environmental licence application, known
as the RCA/PCA, in May 2014. Supram technicians conducted the initial site inspection on 26
August 2014 and no issues of note were raised during the visit. The environmental Operating
Licence is expected byApril 2015.

Criteria Commentary
Discussion of
relative
accuracy/
confidence
 The Ore Reserve estimates have been completed to a Feasibility Study level of confidence.
 There is no production data for benchmarking of the Ore Reserve estimate.
 The statement relates to global estimates. Factors that may affect global grade and tonnage
estimates may include: geological interpretation, density assumptions, mining dilution and
recovery and process performance. A detailed grade control plan will be implemented to control
these factors.
 The Micromine pit optimization was run on the prices used in the economic model. The pit
chosen used an Feprice 55% of the Projectprice. This represents a veryrobustpit selection.
