Australian based iron ore exploration and development company, Kogi Iron Limited (ASX: KFE) (“Kogi” or the “Company”) is pleased to update shareholders in respect of activities related to its 100% owned Agbaja Iron Ore Project located in Kogi State, Republic of Nigeria, West Africa (“Agbaja” or “Agbaja Project”) (refer Figure 1).
Resource Definition – Drilling
Further to its ASX announcement dated 28 February 2013, the Company has now completed an additional 30 hole diamond drilling program at the Agbaja Project (refer Figures 2 and 3). This represents the last component of the resource definition program designed to complete drilling of the 15km[2] Stage 1 Resource Area (refer Figure 2).
A total of 726 reverse circulation (“RC”) holes were drilled, including 138 RC holes completed in the current dry season program, covering an additional 1.2km[2] . RC drilling has been carried out at a spacing of 200 x 100m within the Stage 1 Resource Area.
A total of 41 PQ diamond holes were drilled, including 30 diamond holes in the current dry season program. The diamond drilling has been carried out at a spacing of approximately 400 x 800m within the Stage 1 Resource Area.
The purpose of the diamond drill holes is as follows:
-
As part of the QA/QC program for mineral resource estimation to twin 41 RC drill holes to cover the full extent of the Stage 1 Resource Area to confirm the thickness, grade and geological characteristics of the Laterite and Oolite units;
-
To obtain representative measurements of bulk density and increase confidence in the estimation of resource tonnages;
-
To obtain samples for additional physical rock strength tests, and
-
• For the preparation of additional bulk sample composites for metallurgical testing.

Following completion of geological and geotechnical logging, bulk density measurements, core photography and core cutting at ALS Metallurgy in Perth, one quarter of the core will be submitted for head assay, one half utilised for the preparation of representative bulk sample composites for the next stages of metallurgical test work, and one quarter retained as a reserve for future purposes.
The diamond drill core is being prepared for shipment to Perth, Australia.
Resource Definition – Mineral Resource Update
Global, independent mining consulting group, Coffey, is engaged by the Company to prepare a mineral resource update in accordance with the JORC Code (2004) guidelines. The mineral resource update will incorporate all drill results from the 2012 and 2013 RC and diamond drilling programs.
The additional RC and diamond drilling completed since the assay cut off date for the maiden mineral resource of 28 August 2012, will increase the area covered and the confidence levels within the Stage 1 Resource Area.
The mineral resource update is now scheduled for completion late in the September 2013 quarter. This is later than earlier advised and results from transport delays in shipping drill samples from Nigeria.
Exploration Target
The current Exploration Target[1] estimate for the channel iron deposits and overlying laterite on the Company’s land holdings is 1.6 to 2.7 billion tonnes at 35 to 50% Fe. This estimate includes 1.2 to 2 billion tonnes at 35 to 50% Fe within the Agbaja Project exploration licence EL12124 (inclusive of the Stage 1 Resource Area maiden Inferred Mineral Resource estimate of 488 million tonnes at 43% Fe (refer ASX Announcement dated 28 September 2012)).
The Company has commenced a program to review and update the Exploration Target for EL12124 with a view to applying the information gained from the resource definition drilling, plus recent scout drilling, to better define the exploration potential at the Agbaja Project.
As announced to ASX on 28 February 2013, the Company has completed 25 scout RC drill holes to the west and south of the Stage 1 Resource Area on EL12124 (refer Figure 2), and additional scout RC holes to the northeast of EL12124.
Geological mapping along the west escarpment of the Agbaja Plateau and prospecting pits excavated by the Company in 2011 documented the occurrence, and laterally extensive distribution, of ferruginous laterite underlain by oolitic-pisolitic ironstones elsewhere on the Agbaja Plateau within EL12124, similar to the iron mineralisation defined in the Stage 1 Resource Area. Most of these 2011 exposures were not able to determine the full thickness of the iron mineralisation. The recently completed scout drilling program was designed to test the full thickness, grade and continuity of the iron mineralisation on traverses at spacings from 3 to 4km apart.
The earlier prospecting and recent scout drilling data, combined with acquired high resolution digital satellite imagery, will be utilised to update the Exploration Target for EL12124. It is expected this update will be completed in the September 2013 quarter.
Metallurgical Test Work
Following the completion of the Phase 1 metallurgical test work program, the Company engaged Bateman Engineering (now part of the global Tenova Iron & Steel and Mining Industries group) (“Bateman”) to review the Phase 1 test work results and propose a conceptual metallurgical flow sheet, which would then be validated and optimised through a series of laboratory scale metallurgical tests. Bateman has now completed its review and has proposed a conceptual flow sheet.
1 The estimates of exploration target sizes mentioned in this report should not be misunderstood or misconstrued as estimates of Mineral Resources. The estimates of Exploration Target sizes are conceptual in nature and there has been insufficient exploration completed to date to determine the quantity and grade, or to estimate a Mineral Resource in accordance with the JORC Code (2012) guidelines. Further, it is uncertain if future exploration will result in the determination of a Mineral Resource.

The conceptual flow sheet contemplates feed size reduction to minus 0.6mm followed by simple gravity separation using spiral concentrators and wet, high intensity magnetic separation to upgrade the iron mineralisation from an average in-situ grade of 42.7% to 56-58% Fe.
The next step of the Phase 2 metallurgical test work program involves validating and optimising the conceptual flow sheet through a series of laboratory scale tests using representative composite samples prepared from the 2012 PQ diamond drill holes.
The Phase 2 metallurgical test work program remains on schedule for completion by the end of the June 2013 quarter.
Environmental and Social Impact Assessment
The Company has engaged Nigerian environmental consulting firm, Greenwater Environmental Services Limited (“Greenwater”), to undertake the first phase of an Environmental and Social Impact Assessment (“ESIA”) for the Agbaja Project in accordance with the requirements for all mining development projects under Nigeria’s Environmental Impact Assessment Act (86/1992). The acquisition of baseline and social data for the ESIA is envisaged to take approximately 12 months to complete.
During the March quarter, Greenwater completed dry season baseline data gathering. In the forthcoming wet season Greenwater will undertake its wet season baseline work program. Data collection is extensive and includes meteorology and air analysis, socio–economic and health conditions, geophysical studies, vegetation and wildlife, waste management, soil and surface water studies.
