STRONG DRILLING RESULTS TO UNDERPIN FEASIBILITY STUDY ON JAMBREIRO IRON ORE PROJECT
RESOURCE UPGRADE DUE NEXT MONTH AS CENTAURUS PUSHES TOWARDS FIRST PRODUCTION IN LATE 2013
International iron ore company Centaurus Metals Limited (ASX Code: CTM ) is pleased to report that the Bankable Feasibility Study on its 100 per cent-owned Jambreiro Iron Ore Project in Brazil has been strengthened by outstanding results from the recently completed RC in-fill drilling campaign.
The results, which are the first received from the in-fill program, highlight the quality and consistency of the key Tigre and Cruzeiro deposits. These deposits will be the basis of Jambreiro’s initial development ahead of production at the end of next year.
The current JORC Resource estimate at Jambreiro stands at 116.5 million tonnes grading 26.8% Fe (Measured, Indicated and Inferred). The in-fill program has strengthened the Company’s confidence in the resource and will lead to an up-grade of the resource by the end of May. This upgrade will focus primarily on upgrading the respective categories of the resource, rather than increasing the overall quantity.
This revised resource will form the basis of the Bankable Feasibility Study (BFS), which is underway.
Recently completed pilot plant testwork has shown that the friable itabirite ore, with a head grade consistent with the overall Resource base, can be upgraded to a 65.6% Fe product with low impurities (2.8% SiO2, 0.9% Al2O3 and 0.01% P) using a simple magnetic separation process.
The first results from the in-fill program include a continuous interval of 106.0 metres at 30.7% Fe from 27.0 metres in drill hole JBR-RC-12-0114. This intersection represents the widest continuous interval recorded to date at the project.
The in-fill drilling program focussed on the mineralisation which will underpin the first four years of production from the Tigre and Cruzeiro Deposits.
The Tigre Deposit
Highlights of the recent results from the Tigre Deposit (Figure 1) include the following continuous intervals ( see attached Appendix A for a full list of recent drilling intersections from the Tigre Deposit ):
-
106.0 metres @ 30.7% Fe, 3.6% Al2O3 and 0.03% P from 27.0 metres in Hole JBR-RC-12-0114
-
87.0 metres @ 32.3% Fe, 4.3% Al2O3 and 0.04% P from 23.0 metres in Hole JBR-RC-12-0118
-
59.0 metres @ 32.9% Fe, 3.8% Al2O3 and 0.03% P from 15.0 metres in Hole JBR-RC-12-0121
-
55.0 metres @ 34.2% Fe, 1.9% Al2O3 and 0.03% P from surface in Hole JBR-RC-12-0120
-
53.0 metres @ 32.7% Fe, 4.0% Al2O3 and 0.03% P from 49.0 metres in Hole JBR-RC-12-0122
-
45.0 metres @ 35.5% Fe, 2.8% Al2O3 and 0.04% P from 15.0 metres in Hole JBR-RC-12-0137
-
38.0 metres @ 36.9% Fe, 3.5% Al2O3 and 0.02% P from surface in Hole JBR-RC-12-0138
-
33.0 metres @ 39.6% Fe, 2.9% Al2O3 and 0.05% P from 24.0 metres in Hole JBR-RC-12-0123
-
30.0 metres @ 38.5% Fe, 2.6% Al2O3 and 0.04% P from 7.0 metres in Hole JBR-RC-12-0140
-
22.0 metres @ 38.8% Fe, 3.2% Al2O3 and 0.03% P from surface in Hole JBR-RC-12-0136

Many holes contain particularly wide intersections of a higher grade nature than seen in previous drilling. Drill holes JBR-RC-12-0114 (106.0m at 30.7% Fe) and JBR-RC-12-0118 (87.0m at 32.3% Fe) in particular demonstrate excellent continuity of wide and relatively high-grade friable ore from near surface in the heart of the Tigre Deposit.
The southern extension of the Tigre Deposit continues to deliver higher grade friable mineralisation from surface, demonstrated in drill holes JBR-RC-12-0138 (38.0m at 36.9% Fe) and JBR-RC-12-0136 (22.0m at 38.8% Fe). This zone continues to present the best start up option for mining, with higher grades of ore at or near surface with favourable strip ratios.
The Cruzeiro Deposit
Highlights of the recent results from the Cruzeiro Deposit (Figure 1) include the following continuous intervals ( see attached Appendix B for a full list of recent drilling intersections from the Cruzeiro Deposit ):
-
30.0 metres @ 33.9% Fe, 2.3% Al2O3 and 0.02% P from surface in Hole JBR-RC-12-0127
-
27.0 metres @ 36.0% Fe, 3.3% Al2O3 and 0.03% P from 4.0 metres in Hole JBR-RC-12-0128 24.0 metres @ 33.3% Fe, 5.1% Al2O3 and 0.07% P from 6.0 metres in Hole JBR-RC-12-0125 22.0 metres @ 32.7% Fe, 1.5% Al2O3 and 0.01% P from surface in Hole JBR-RC-12-0126
Results from the Cruzeiro Deposit continue to highlight the shallow, relatively high-grade nature of the deposit. The mineralisation at Cruzeiro dips sub-parallel to the natural surface and when combined with the southern extension of the Tigre Deposit will provide excellent low strip ratio material for the planned startup of mining.
Resource and BFS Study Up-date
All resource drilling at the Jambreiro Project was completed in March. The drilling will convert the majority of the mineralisation earmarked for the first four years of production into JORC Measured Resources, comprehensively covering the estimated two-year project payback period.
All drill samples have now been submitted to the Intertek laboratory with results expected by early May. The Company is well advanced in the data validation and geological interpretation of the deposits at Jambreiro and the new JORC Resource estimate is on schedule to be completed by the end of May.
A comprehensive program of metallurgical sampling was undertaken at the start of the year with samples covering the quarter-by-quarter current mining sequence for the first four years of production. Following the successful initial pilot plant program referred to above, a significantly larger sample of Jambreiro ore is now being prepared for an extended pilot plant test work program.
The new JORC Resource base will form the platform for a new JORC Ore Reserve estimate and mine planning that will feed into the Jambreiro BFS which is underway and due for completion in September 2012.
A diamond rig has been mobilized to the Jambreiro Project to start the geotechnical drill program required as part of the BFS. Centaurus has engaged WALM Engenharia e Tecnologia Ambiental Ltda to supervise the geotechnical drilling and provide input into the BFS on geotechnical, water and waste management matters. WALM is a Brazilian based engineering group with extensive experience in engineering, design and execution studies of several mines in the Iron Quadrangle region of Brazil that have similar characteristics to the Jambreiro project.

Centaurus’ Managing Director, Mr Darren Gordon, said the latest results were outstanding and would further strengthen the economics of the Jambreiro Project.
“ The widths and grade of mineralisation coming from the friable ore are particularly encouraging and provide great confidence that we have a resource base that will form the foundation of a long life mining operation,” Mr Gordon said.
“The pilot plant work has shown that we can produce a high-grade sinter product from the Jambreiro ore that will be highly sought after in the domestic steel industry in Brazil. The BFS that is underway is expected to confirm the strong economics that were delivered in the Pre-Feasibility completed in November last year.”
