("ZIOC" or the "Company")
Zanaga Project Mineral Resource Update
Zanaga Iron Ore Company Limited (AIM:ZIOC) is pleased to announce the following Mineral Resource update relating to the expansion and improvement in resource classification on the Zanaga Iron Ore Project (the "Zanaga Project") in the Republic of Congo (Congo Brazzaville). The updated resource estimate was prepared by independent consultants SRK Consulting (UK) Ltd ("SRK") and reflects additional drill-hole and assay data obtained since the preparation of the last estimate reported on 5 April 2011.
Highlights
·; Iron ore mineral resource expands to 4.3 billion tonnes at an average grade of 33.0% Fe from 4.0 billion tonnes at an average grade of 33.9% Fe, reported in accordance with the JORC Code
·; Improvement in resource classification: Ratio of Measured, Indicated and Inferred Resources has improved to 3%:59%:38% respectively, representing a significant change from the previous estimate announced on 5 April 2011 of 0%:43%:57%
·; Total of 126,984 metres drilling included in updated JORC statement
·; Mineral Resources derived from only 25km of the 47km orebody trend
Clifford Elphick, Non-Executive Chairman of ZIOC, commented:
"I am pleased to announce an improvement in the JORC compliant Mineral Resource classification as well as an expansion in Mineral Resource inventory at the Zanaga Iron Ore Project. A significant drilling programme has been conducted on the Zanaga Project and today's results provide further confidence in the large scale orebody."
Zanaga Iron Ore Project Mineral Resource Grows to 4.3 billion tonnes at 33.0% Fe
Mineral Resource Statement
Classification | Tonnes (Mt) | Fe (%) | SiO2 (%) | Al2O3 (%) | P (%) | Mn (%) | LOI (%) |
Measured | 149 | 38.7 | 39.1 | 2.4 | 0.047 | 0.093 | 1.2 |
Indicated | 2,540 | 34.1 | 43.6 | 2.8 | 0.050 | 0.112 | 1.0 |
Inferred | 1,650 | 31 | 46 | 4 | 0.05 | 0.12 | 2 |
Total | 4,339 | 33.0 | 44.3 | 3.3 | 0.049 | 0.114 | 1.3 |
Reported at a 0% Fe cut-off grade within an optimised Whittle shell representing a metal price of 130 USc/dmtu.
The Mineral Resource statement set out above is reported in accordance with the terms and definitions included in the Australasian Joint Ore Reserves Committee (JORC) Code (2004) as at September 2011. As at this date, the total Mineral Resources reported at a 0%Fe COG constrained within an optimised Life of Mine (LOM) pit shell, amounts to 4.34 Bt grading 33.0% Fe, 0.049% P, 44.3% SiO2, 3.3% Al2O3, 0.114% Mn, and 1.3% LOI. The shell was determined by SRK using operating costs derived from the Pre-Feasibility Study work streams and a selling price of 130 USc/dmtu based on the SRK 3rd Quarter 2011 consensus market forecast for Brazilian fines without adjustment. The table above presents the Measured Mineral Resource, Indicated Mineral Resource, the Inferred Mineral Resource and the total Measured plus Indicated plus Inferred Mineral Resource based on drilling to 26 August 2011 and as estimated by SRK in September 2011. The Competent Person, Dr John Arthur of SRK, has given his permission for the publication of this information in the form and context within which it appears.
Drilling programme summary
The updated JORC Mineral Resource is estimated on drilling completed on the Zanaga Project up until 26 August 2011 and includes an additional 59,618 metres (88% increase) & 951 holes (45% increase) to drilling carried out for the previous resource statement announced on 5 April 2011. In addition, a total of 43,373 XRF analyses and 37,617 Niton analyses were used to model the mineral resource, more than twice the amount used in the previous mineral resource statement. Please see the table below for an update on drilling completed.
Drilling completed | Metres |
at 30 Jun 2010 (IPO JORC resource) | 42,706 |
30 Jun 2010 - 24 Nov 2010 (previous JORC resource, announced 5 Apr 2011) | 24,660 |
24 Nov 2010 - 26 Aug 2011 (new JORC resource, announced 26 Oct 2011) | 59,618 |
Total to date | 126,984 |
Geological Summary
The north-south oriented greenstone belt which hosts the Zanaga deposit has been defined by an airborne geophysical survey over 47 km in length, and is typically between 0.5 and 3.0 km in width.
The iron bearing lithologies within the Zanaga deposit are itabirites/BIF, interbedded with basic lavas. Typically, the itabirites consist of layers of iron-rich and quartz rich meta-sediments which alternate on a millimetre to centimetre scale and which have been crosscut by late intrusions and dolerite dykes.
The weathered itabirite units which overlie un-weathered ore are typical of iron ore deposits and characterised by an enrichment in iron due to a mass reduction and associated leaching of the silicate layers.
