HIGHLIGHTS - Technical

Yarraloola Project – West Pilbara

  • Robe Mesa maiden Inferred Resource for pisolitic iron-stones (CID) of 73 Mt @ 53.9% Fe (equivalent calcined iron, FeCa of 60.4%) + 8.0% SiO2 + 3.4% Al2O3 + 0.04% P + 10.8% LOI above a cut-off grade of 50% Fe (FeCa>55%).

  • Inferred Resource includes an initial higher grade portion of 20 Mt @ 55.7% Fe (FeCa of 62.3%) + 6.2% SiO2 + 2.9% Al2O3 + 0.04% P + 10.6% LOI at above a cut-off grade of 55% Fe (FeCa of 60%).

  • Inferred Resource consists of an upper (outcropping) zone up to 25m thick and lower (subcropping) zone up to 25m thick of sub-horizontal pisolitic iron-stone mineralisation separated by up to 20m of shaley material.

  • Inferred Resource (Fe>50%, FeCa>55%) is characterised by low phosphorus (P<0.05%) and high loss on ignition (LOI of 9 to 12%) and is open to the North, East and West in most areas and further drilling is required to close the envelope.

  • Three 202m deep RC holes show magnetite mineralisation in the Ashburton Trough is hosted by chloritic schists with compositions indicative of intermediate to rhyolitic volcanics that supports an “Algoma-style” (volcanic) setting rather than an outlier of the Hamersley basin sequence.

  • In the Ashburton Trough, YAR091 reported 91m @ 25.4% Fe down-hole from surface and YAR093 intercepted 29m @ 31.9% Fe (28-57m down-hole) and 55m @ 31.8% Fe (77-132m down-hole) with no indications of crocidolite (blue asbestos).

  • In the Ashburton Trough, initial grind-size analysis for magnetite recovery by Davis Tube indicates the host-rock is “soft”, high-quality concentrate was recovered from -63 microns and the best 5m-interval sample reported 36.9% magnetite mass recovery @ 69.4% Fe + 3.36% SiO2.

Project Summaries

Yarraloola Project – West Pilbara

Background

The Yarraloola tenements cover 1450km[2] in the western part of the Hamersley Basin and adjacent parts of the Ashburton Trough in the West Pilbara. In parts, these Archaean and Proterozoic-aged rocks 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 ironstone or Channel Iron deposits (CID’s). These are basin margin sediments of the Carnarvon Basin that 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 received final assay results from an RC drilling programme on two prospects.

  1. A section of the palaeo Robe Channel system located on E08/1060 and E08/1686.

  2. Magnetite schists in the Ashburton Trough on E08/1686 and E08/1826 (Fig 1).

Completed in the last quarter, the programme consisted of 28 RC drill-holes for a total of 2168m, of which 25 holes for 1562m were drilled into the Robe Mesa and 3 holes for 606m were completed on the Ashburton schist. Samples (1m interval) were submitted to Bureau Veritas Laboratories in Perth for extended iron-ore suite XRF and trace-element analysis by ICP on fused disk. After the assay results were received, all the geochemical and geological data from the Robe Mesa was submitted to Optiro Pty Ltd in Perth for an independent assessment of the tonnage potential. A maiden Inferred Resource with attached JORC-tables was reported in full on 3 February 2015. Geochemical results from the magnetite schists and the associated host-rocks in the Ashburton Trough have been reviewed by CZR and were reported with an attached JORC-table on 11 February 2015.

Results

Robe Mesa Pisolitic Iron-stone – CID Mineralisation

The geological model for the pisolitic ironstone in the Robe Mesa which reflects both surface mapping and an interpretation of the drilling is shown on Fig 2, 3 and 4 and can be summarised as follows.

  1. Two intervals of dark reddish brown, flat-lying, pisolitic iron-stone sediments that are each up to 25m thick are separated by up to 20m of lighter coloured shaley to sandy material.

2

==> picture [92 x 35] intentionally omitted <==

  1. The upper interval of pisolitic iron-stone is well exposed as a continuous outcropping sheet on the mesa while the lower level is outcrops in part but is consistently intersected by drilling.

  2. Volume calculations utilised samples of pisolitic iron-stone with iron (Fe) >50% in intercepts that are greater than 5m thickness and include no more than two (dilutionary) samples within an intercept with Fe<50%. The conversion to tonnage used a specific gravity (SG) of 2.6.

Optiro reported the following tonnages from Surpac using the detailed parameters that are attached in Appendix 1 of the CZR announcement to the ASX on 3 February 2015.

Table 1. Robe Mesa – Mineral Resource Estimate at January 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 January 2015 – reported above a Fe cut-off grade of 55% .

Inferred 20 55.7 6.2 2.9 0.11 10.6 0.04 0.02 62.3

Overall, the pisolitic iron-stone in the Robe Mesa represents a low phosphorous (P) style of “channel-iron” mineralisation which will upgrade significantly (reported as Feca content) during the calcining process to remove the volatiles (mostly crystalline water) prior to smelting. Further drilling to assess the geological, mineralogical and metallurgical properties of the Robe Mesa mineralisation is planned.

Ashburton Trough Magnetite Mineralisation

The three RC holes for a total of 606m into the Ashburton Trough provided representative geological material for geochemical analysis within a 12km long and 800m wide prospect that hosts high-order magnetic anomalies on E08/1686 and E08/1826 (Fig 1). Mapping of the prospect has identified sporadic outcrop of magnetite-bearing schists and quartzites along 6km of the 12 km strike length (Fig 5). The strongly foliated and coarser grained textures differentiate this magnetite mineralisation from the finer grained, more siliceous and less deformed units of the Hamersley Basin.

Two of the inclined (-60) drill-holes recovered significant intercepts with magnetite. In the south YAR091 intersected 100m downhole of magnetite schists before entering a richly chloritic sequence with compositions typical of rhyolitic to dacitic volcanics (Fig 5). Further north, YAR093, intersected an upper zone from 28 to 75m (29m downhole) and a lower intersection extending from 76 to 132m (56m downhole). Analytical results summarised in Table 3 were then used to generate

For grind-size optimisation, bulked RC-samples were processed to determine the optimal sizefraction for a magnetite concentrate with Fe @ 67% from the Davis Tube. YAR091-0-45m and YAR093-28-53m each produced a good quality concentrate in the grind-size range of 63 and 45 microns, while YAR091-45-105m and YAR093-76-129m required grinding to 38 microns to produce a concentrate of the same quality. As a result, all Davis Tube recovery was undertaken at -38 micron to standardise the mass recovery and concentrate analysis. These results are summarised in Table 4.

Overall, drilling shows the following.

  1. There is a relatively thin (<30m deep) near-surface oxidation zone

  2. The geochemistry indicates Fe-contents typical of the values from most well documented iron-formations

  3. The grind-size optimisation suggests the magnetite-host-rock is relatively soft

  4. The Davis Tube shows the magnetite recoveries are relatively consistent with low levels of contaminants such as phosphorous. Further work is planned to assess the commercial significance of the magnetite schists in the Ashburton Trough.

In addition to studies of the magnetite-bearing rocks, the geological and geochemical features of the host-rocks in the Ashburton Trough sequence have been reviewed as part of the programme to establish the potential geological setting and origin for the mineralisation. Evidence of quiet water sedimentation is represented by graphitic schists and carbonates. This appears to be associated with evidence of andesitic to rhyolitic volcanism reflected by the major and trace-element geochemistry

of interbedded chloritic schist (Fig 6). These features are regarded as being indicative of “Algomastyle” magnetite mineralisation.

In addition, a recent assessment of the trace element signatures from the volcanic rocks suggests they developed within a continental margin setting (Fig 7). As such, the sequence may also be prospective for volcanic hosted base-metals (copper, lead and zinc) and epithermal gold mineralisation. Further work is being planned.
