Exploration Update – Iron Ore
Summary
-
The Manager of the Mt Stuart Iron Ore Joint Venture has reported the assay results for a programme of exploration RC drilling completed in December 2013;
-
Best intersections include : 12m @ 57.22% Fe from 22m in CBRC340 and 10m @ 54.87% Fe from surface in MSRC038 in channel iron deposits (CIDs);
WEST PILBARA, W.A. – Iron
– MT STUART IRON ORE JOINT VENTURE (MSIOJV) ELs 08/1135, 1292, 1330, 1341 , API JV 70% (Manager), Cullen 30%, and contributing. Cullen retains 100% of Other Mineral Rights
The MSIOJV is between Cullen - 30%, and API Management Pty Ltd (“API”) - 70%. The shareholders of API are the parties to the unincorporated joint venture known as the Australian Premium Iron Joint Venture (APIJV). The participants in the APIJV, Aquila Steel Pty Ltd (a subsidiary of Aquila Resources Limited, ASX: AQA) 50%, and AMCI (IO) Pty Ltd 50%.
The Manager provided the following project update including assay data in relation to exploration drilling activities completed in the December 2013 Quarter:
“MSIOJV Project Update 1/7/2013 – 21/2/2014
During the period the following work was completed:
-
RC drill pads prepared and access maintenance continued.
-
RC drilling programme with 43 RC holes for 1,372m completed.
-
Winze at Catho Well backfilled and site rehabilitated.
2
Catho Well (E08/1330)
Rehabilitation of bulk sample winze has been completed.
Drill pads and approximately 2km of track were cleared in preparation for RC drilling.
10 RC drill holes for 370m were completed at Catho Well assessing the northwest continuation of the Catho Well Channel Iron Deposit (CID) with the best intercept of:
10m @ 54.87% Fe from surface in MSRC038 (Figure 1).
Common features from logging:
-
Vitreous goethite hard capping (Zpw).
-
Alternating mixed (Zpm); comprising goethitic oolitic/pisolitic textures in a clay matrix and Zpg (Goethite dominant zone).
-
Basal unit of goethitic oolitic CID, non-mineralised lithics and an inconsistent clay component (Zpl).
-
A siliceous basal conglomerate is commonly intercepted, overlying basement.
-
A basement of dolomite and shale.
The RC drilling was completed to assess the northwest continuation of the Catho Well paleodrainge outside the current defined Catho Well Mineral Resource. The grade of the CID is maintained however thins to the northwest.
Yanks Bore (E08/1135)
Clearing of tracks and drill pad positions was completed in preparation for RC drilling. Drilling at Yanks Bore targets a low-lying, oolitic CID ridge. 12 RC holes were completed for 312m drilled. The best result was 2m @ 54.83% Fe from 4m in MSRC048 (Figure 1). Samples for potential beneficiation test work have been retained at site pending further assessment.
Cardo Bore (E08/1341)
Clearing of existing tracks (4km) and drill pads positions was completed in preparation for RC drilling. The RC drilling on Cardo Bore CID targeted areas of +50% Fe identified from earlier drilling. 9 RC holes were completed for 336m drilled. The best result returned was 12m @ 57.22% Fe from 22m in CBRC340 (Figure 1). Results confirm isolated areas of +54% Fe within a broader +50% Fe CID.
Mt Stuart (E08/1292)
Clearing of existing tracks (2km) and drill pad positions was completed in preparation for RC drilling. The RC drilling on Mt Stuart targeted a gently sloping remnant CID mesa. 12 RC holes for 354m were completed with the best intercept of 2m @ 55.56% Fe from 2m in MSRC025 (Figure 1). Samples for potential beneficiation test work have been retained at site pending further assessment.

ABOUT CULLEN : Cullen is a Perth-based minerals explorer with a multi-commodity portfolio including projects managed through a number of JVs with key partners (FMG, APIJV (Aquila-AMCI), Hannans Reward, Northern Star, Matsa and Thundelarra/Lion One Metals), and a number of projects in its own right. The Company’s strategy is to identify and build targets based on: data compilation, field reconnaissance and earlystage exploration (particularly geochemistry). A number of Cullen’s 100%-owned projects are at the target drilltesting stage.
Competent Person Statement
Exploration Results (MSIOJV)
The information in this report that relates to exploration results for the MSIOJV is based on information compiled by Mr Stuart Tuckey, who is a Member of The Australasian Institute of Mining and Metallurgy and is a full-time employee of API Management Pty Ltd. Mr Tuckey has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr Tuckey consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.

JORC Code, 2012 Edition – Table 1 (MSIOJV)
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
-
Criteria JORC Code explanation Sampling Nature and quality of sampling (eg cut channels, random chips, or techniques specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.
-
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
-
Aspects of the determination of mineralisation that are Material to the Public Report.
Commentary
-
Samples for analysis were collected every 2m down hole directly from the cyclone after passing through a three tier riffle splitter mounted on the RC drilling rig. Each sample represented 12% (by volume) of the drilling interval with an average weight of 4kg for a 2m interval. Standards and duplicates were inserted into the sample sequence at the rate of 1 in 50 samples, i.e. every 25th sample was a standard or a duplicate. These samples were used to test the precision and accuracy of the sampling method and laboratory analysis.
-
Sample analysis was completed by SGS Laboratories in Welshpool, WA. Samples were sent direct to the laboratory, sorted, dried and pulverised using a ring mill.

|---|---|---|
| In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, |
Samples were analysed for a suite of elements by X-Ray Fluorescence Spectrometry and gravimetrically for Loss on Ignition (LOI 1000° and LOI 371 °C). Assays were reported to API by email. |
