CENTAURUS LAYS NEW GROWTH FOUNDATIONS WITH MAIDEN 27.6Mt JORC RESOURCE FOR CANAVIAL PROJECT
Emerging project located 10km from flagship Jambreiro Project lifts Guanhães Region resource inventory to +150Mt and company‐wide resources to +200Mt
International iron ore company Centaurus Metals Ltd (ASX Code: CTM ) is pleased to advise that it has established a strong foundation for the future growth and expansion of its flagship Jambreiro Project in Brazil after delivering a maiden JORC Mineral Resource for the Canavial Project , a key satellite deposit located 10km to the south‐west of Jambreiro ( Figure 1 ).
The maiden Mineral Resource estimate, of 27.6 million tonnes at an average grade of 30.5% Fe, has boosted the Company’s JORC compliant resource inventory in the Guanhães region of south‐eastern Brazil to over 152 million tonnes and the Company’s total resource inventory in south‐east Brazil to over 201 million tonnes .
Importantly, the new Canavial Resource estimate includes 15.8 million tonnes grading 33.2% Fe of friable itabirite mineralisation , of which 6.1 million tonnes grading 34.1% Fe has already been converted to Indicated Resources.
With the addition of this friable itabirite Resource at Canavial to that of the Jambreiro Project, the friable component of the Company’s Guanhães regional footprint now stands at 81.5 million tonnes grading 28.8% Fe with over 70% of this resource base falling into the Measured and Indicated categories.
Mineral characterization and process testwork is underway focusing on the friable itabirite material at Canavial. Results of this testwork are due by the end of August 2013. The Company expects to be able to achieve similar beneficiation results to those achieved at Jambreiro, such that a high grade, low impurity concentrate can be produced.
The Canavial Project is advantageously located in an area predominantly covered by a eucalypt plantation, which means that environmental licensing for potential future project development will be relatively simple, as was the case with Jambreiro.
The maiden Canavial JORC Mineral Resource estimate is set out in Table 1 below, with additional technical details of the Resource provided in Appendix A attached:

Canavial’s Link to the Jambreiro Project
Given its location just 10km from the Jambreiro Project, Canavial has the potential to provide an additional source of friable itabirite to the Jambreiro Project. Jambreiro itself has a JORC Mineral Resource estimate (combined Measured, Indicated and Inferred) of 125.2 million tonnes grading 26.7% Fe including an Ore Reserve of 48.5 million tonnes grading 28.1% Fe of friable ore .
Recent drilling at Jambreiro has been targeting the conversion of the friable material currently in the Inferred Resource category. The results from this drilling are imminent and an updated resource is expected before the end of June.
Centaurus has commenced detailed engineering works on the Jambreiro Project and recently received the key Installation Licence (LI) for the Project, allowing on‐site construction activity to commence. As outlined earlier this week, Centaurus is targeting production of first iron ore concentrates at Jambreiro by mid‐2014 as it completes potential life‐of‐mine off‐take negotiations with domestic steel customers in Brazil in the coming months.

About the Canavial Project
The mineralisation at Canavial is divided into two zones; the Central Zone and the Southern Zone ( see Figure 2 ). The Central Zone mineralisation strikes in a NW‐SE orientation and has a strike extent of approximately 1,000m, dipping between 20 and 45⁰ to the north‐east.
The shallow zones of friable itabirite mineralisation are between 15 to 35m thick and extend over 100m down‐ dip between holes on section (s ee Sections 4 and 5 in Figures 3 and 4 ). The geometry and material characteristics of the Central Zone mineralisation is expected to lend itself to a low strip ratio and has the potential to support a low‐cost open cut operation.
The Southern Zone is a NW‐SE zone with a strike extent of around 700m where the mineralisation is sub‐ vertical ( see Section 10 in Figure 5 ). The change in dip angle is due to the proximity of the nose of a large‐scale fold in the south eastern limit of the tenement area. The zones of friable itabirite mineralisation are between 10 to 20m thick and vertical to sub‐vertical.
The mineral assemblage of the Canavial friable itabirite mineralisation is similar to that of the Jambreiro Project with hematite (probably martite) and magnetite being the dominant iron oxides with quartz and some clay minerals. The main difference to the Jambreiro ore is the higher percentage of goethite and limonite present in the mineralisation. Locally, some shallow mineralised intervals have elevated levels of Al2O3 and P due to the clay minerals.
It is expected that these gangue minerals will clean up in the beneficiation process to produce a high iron, low impurity iron product similar to that which is to be produced at Jambreiro.
Commenting on the maiden resource at Canavial, Centaurus’ Managing Director, Mr Darren Gordon, said: “This is a great result from a standing start at Canavial, with drilling delivering a solid maiden JORC resource which has a significant component of friable itabirite mineralisation similar to what we have 10km down the road at Jambreiro.
“While we still have to complete metallurgical testwork and other studies to progress this Project, all the indications are that it could develop very quickly as a low‐cost bolt‐on growth opportunity for the main processing operation at Jambreiro.
“This highlights the significant exploration upside within the Guanhães region and the opportunities to continue to grow our resource inventory. We have a maiden resource for our other key satellite project in this region, Candonga, due within a month or so and there are many other untested exploration targets within our broader regional tenement holding. We plan to test these in the future, once we have a fully‐fledged mining operation up and running at Jambreiro.”
