PFS Study
Shree has previously announced a PFS study on a staged project development as following: o Stage 1 : DSO
-
Stage 2 : BFO
-
Stage 3 : Magnetite
The PFS outcomes have been updated by the company for DSO phase based on the new resource estimates, with the following update on the project:
-
Resource is outcropping – no pre-stripping required
-
Close to existing infrastructure – road and port facilities
-
FOB Cost Estimate – A$ 48 per tonne
-
Cash operating surplus, pre tax (DSO Phase) - A$ 39 million using, 58% Fe CFR North China current spot prices.
-
Statutory approvals well advanced
-
Discussions with potential off-take parties well advanced
-
Discussions with potential mining contractors well advanced
-
Work to upgrade PFS to a Feasibility study for DSO phase in progress.
-
Targeting production within 6 months of approvals.

Background
The iron mineralisation at the Nelson Bay River Iron Project (EL41/2004) is hosted by a 10 to 28 metres wide mafic dyke, which crosses cuts the country rocks and increases in width with depth. Within this dyke is a magnetite-rich section and oxidation of the magnetite has generated goethitehematite mineralisation to varying depths. During 2011-12, the company drilled 1,259 m RC along 23 holes for DSO resource delineation (Figure 1).

Resource Estimation
In view of the 2011 RC drilling, the DSO resource estimates were revised. The revised DSO resource estimates at 0.7 Mt show an increase of 55% in the resources over the 2010 figures of 0.45 Mt with similar iron and other element values.
The DSO resource estimate is based on information from 6 diamond and 17 RC percussion holes, totalling 1175.3 m (Table 2). From these holes, 217 composites of 1m length were used for the resource modelling.

An initial geological interpretation of the goethitic-hematite mineralisation was made using a combination of iron grades and geological logging. A nominal cut off 54% iron was used in conjunction with geological sense and mineral coherency to create the high-grade wireframes (Figure 2).

Resource modelling used Ordinary Kriging with a maximum search distance of 112.5m and a minimum number of two data points for a block size of 5m by 25m by 5m. The resources were reported from within the high-grade mineral wireframe with no cut off grade.

As a result of the 2011 drilling, new resource estimates for the goethitic-hematite (DSO and BFO) mineralisation for the Project are given in Table 3.
Table3: Nelson Bay Updated DSO + BFO Resource Estimates
| Material Type |
Resource Category |
Mass (Mt) | Grade % | Grade % | ||||
|---|---|---|---|---|---|---|---|---|
| Fe | Al2O3 | P | S | SiO2 | LOI | |||
| DSO | Indicated | 0.34 | 57.4 | 1.3 | 0.075 | 0.035 | 9.2 | 6.4 |
| DSO + BFO |
Inferred | 1.10 | 50.8 | 2.2 | 0.044 | 0.055 | 18.1 | 5.5 |
| Total Resource | 1.43 | 52.3 | 2.0 | 0.051 | 0.050 | 16.0 | 5.6 |
As no drilling during 2011 was carried out for the BFO resource area the values for the BFO resource have been retained from the 2010 Resource estimate. However, reinterpretation of the geology based on the information gleaned from the 20111 drilling suggested a small narrow zone of higher grade mineralisation in the core of the gossan zone at 54.5 to 55.5% Fe. Shree believes that this material, using Platts 52% Fe index as a reference point, could be sold as low-grade DSO and thus has the potential to increase the size of the DSO resources.
Additionally, peripheral to the main DSO resource there is low-grade material, which could be processed by the BFO processing circuit and thus has the potential to increase the size of the BFO resources.
The revised geological interpretation has meant a modification to the Skarn Dyke iron resource estimate reported in the 2010 resource estimate. This is due to the greater depth of oxidation associated with the Oxide Iron mineralisation eating into the fresh rock skarn mineralisation. The new
