Quarterly Activities Report to 30[th] June 2015
HIGHLIGHTS - Technical
Yarraloola Project – West Pilbara
-
Statutory and heritage approvals were obtained for a reverse circulation drill programme consisting of approximately 66 RC holes totalling 6,700m and 3 diamondholes totalling 1500m.
-
A total of 50 reverse circulation holes each about 70m will infill the Inferred Resource of pisolitic-ironstone on the Robe Mesa.
-
A total of 16 reverse circulation holes, each of 200m, will examine the geology, thickness, orientation and mass-yield of magnetite mineralisation hosted within a sequence of intermediate and acid volcanics and fine grained sediments in the Ashburton Trough.
-
Three diamond drill-holes each of 500m will provide representative geological cross-sections through the magnetite-rich schists in the Ashburton Trough that typically outcrop poorly. The drilling will provide samples for density, strength and grinding studies.
Project Summaries
Yarraloola Project – West Pilbara
Background
The Yarraloola tenements now cover an area 1,071km[2] in the western part of the Hamersley Basin and adjacent parts of the Ashburton Trough in the West Pilbara following a compulsory year 6 reduction of two exploration licences.

In parts, the Archaean and Proterozoic-aged rocks within the Yarraloola project are overlain by younger sediments of the Carnarvon Basin. Sediments in the Hamersley Basin include iron-rich members of the Marra Mamba, Brockman and Boolgeeda Iron Formations. In the south, the Yarraloola tenements are transected by the RioTinto Ltd owned Robe River pisolitic iron-stone or Channel Iron deposits (CID’s). The pisolitic iron-stones are basin margin sediments of the Carnarvon Basin and currently support large-scale mining operations at Warramboo, Mesa A and Mesa J (Fig 1). In addition to the established infrastructure associated with Yarraloola, there is a new haul-road and port infrastructure being developed by Iron-ore Holdings Ltd and rail and port facilities are proposed for development by the Baosteel JV. Both of these planned infrastructure projects will traverse the CZR tenements and potentially improve the economics of any iron-ore deposits discovered within the project area
Activities
During the quarter, the company planned and obtained statutory approvals for RC and diamond drilling programmes on the two most advance prospects at Yarraloola.
-
The Robe Mesa located on E08/1060 and E08/1686 (Fig 1, Fig 2); and
-
Magnetite schists in the Ashburton Trough located on E08/1686 and E08/1826 (Fig 1, Fig 3).
Robe Mesa Pisolitic Ironstone (CID) Drill Proposal and activities
The 2015 drilling on the upper part of the Robe Mesa will infill a pattern of 23 holes on an approximate 200m grid completed in late 2014. The purpose of the drilling is to increase the confidence in the independently calculated Inferred Resource at cut-off grades of Fe = 50% and Fe = 55% and announced in February 2015 (refer ASX Announcement dated 3 February 2015 for full details of the resource). A summary of the resource statement is summarised in Tables 1 and 2.
Table 1. Robe Mesa – Mineral Resource Estimate at February 2015 – reported above a Fe cut-off grade of 50% .
| Category | Mt | Fe% | SiO2% | Al2O3% | TiO2% | LOI% | P% | S% | **Feca% ** |
|---|---|---|---|---|---|---|---|---|---|
| Inferred | 73 | 53.9 | 8.0 | 3.4 | 0.13 | 10.8 | 0.04 | 0.02 | 60.4 |
Table 2. Robe Mesa – Mineral Resource Estimate at February 2015 – reported above a Fe cut-off grade of 55% .
| Category | Mt | Fe% | **SiO2% ** | Al2O3% | TiO2% | LOI% | P% | S% | **Feca% ** |
|---|---|---|---|---|---|---|---|---|---|
| Inferred | 20 | 55.7 | 6.2 | 2.9 | 0.11 | 10.6 | 0.04 | 0.02 | 62.3 |
Late in the Quarter, a Heritage Survey cleared areas to accommodate an additional 50 drill-pads on the upper part of the Robe Mesa (Fig 2). This will allow for up to 4000m of RC drilling on the project and provide intercepts through both the upper and lower zones of mineralisation.

In addition, recent field-work has identified historical station tracks which access the area of pisolitic ironstone that was mapped as the Lower Mesa in 2014. More detailed work is planned on the Lower Mesa with a focus on developing access for additional drilling later in the year.
Ashburton Trough - Magnetite mineralisation in Schist
The 2015 RC drilling will extend exploration beyond the first three RC holes completed in 2014 and provide new cross-sections into high-order magnetic anomalies that cover an area of 12km long by 800m wide in the Ashburton Trough on E08/1686 and E08/1826 (Fig 1). The 2014 exploration programme identified magnetite-rich schists hosted by a sequence that included intermediate and rhyolitic volcanics and fine grained siliciclastic sediments. This appears to represent a deeper-water Algoma-style of mineralisation which is a new style of mineralisation in the Ashburton Trough.
Detailed geochemical studies indicate formation on a continental margin.
Results reported to the ASX in February 2015 identified more favourable characteristics of the schisthosted, magnetite mineralisation in the Ashburton Trough compared to other mined magnetite deposits in Australia. In this regard, the schists have Fe-contents and magnetite yields that are typical of other mined deposits, however have a relatively shallow capping of extensively oxidised material (>30m), drill much more rapidly, indicating they are softer, and have low levels of contaminants such as phosphorous.
A recent Heritage Survey provided clearance to conduct eight drill-lines where an initial programme of two holes per section will provide details on the geology, thickness of the magnetite-bearing intervals, geochemistry and mass yield of magnetite (Fig 3). In addition to the RC drilling, three representative 500m diamond drill-holes are planned to recover samples of the magnetite schist beneath the weathering zone for compressive-strength testing and crushing and grinding to determine the work-index. Samples from the drilling will also be analysed for a suite of other elements to determine if the volcanic and volcaniclastic rocks are prospective for gold and basemetal mineralisation.
