The Manager Companies Company Announcements Australian Securities Exchange Exchange Centre 20 Bridge Street SYDNEY NSW 2000 Dear Sir
Nelson Bay River Iron Project: Updated DSO South Pit Reserves
Shree Minerals Ltd (ASX code: SHH) (“the Company”) is pleased to advise the publication of the updated DSO South Pit Reserves for its Nelson Bay River (NBR) Iron Project. The new reserves are based on the the recent drilling programme completed after the 24 October 2012 Reserve Statement The aim of the drilling was to upgrade the resource and revise the Mine Plan for the first two of years of DSO operations.
The new Mineral Resource estimates for the DSO South Pit reflects an increase to 0.87Mt compared to the earlier Mineral Resource estimate of 0.7Mt. The Reserves Estimates for DSO South Pit similarly increases to 0.65Mt compared to the earlier reserve of 0.33Mt.
Mine Plan for DSO Iron Ore
The updated production schedule for the first two years of production is sourced initially solely from the DSO South Pit. .The DSO ore mined only requires crushing and screening to produce a marketable product that requires no further beneficiation. Two separate DSO pits are planned for the first two years of mining the, DSO South Pit followed by the DSO North Pit where the latter is contained within the BFO resource to its north. The updated mine plan and production schedule mines a total of 0.914 Mt of DSO compared to the previous 0.815Mt.
Reserves
The Ore Reserve Estimate was completed by the Minserve Group Pty Ltd in accordance with the 2012 JORC Code guidelines based on the Mineral Resource Estimate completed by Simon Tear of H&S Consultants Pty Ltd (HSC). The methodology and other details are in Annexure 1.
Under the JORC Code, only Measured and Indicated Mineral Resources can be considered for conversion to Ore Reserves after consideration of “Modifying Factors” including mining, processing, economic, environmental, social, and government factors. The Ore Reserve Statement applies solely to the resource estimates in the Measured and Indicated categories.

Information material to understanding the Ore Reserves Material Assumptions
The Updated Reserve Statement is based on the:
-
The Mineral Resource estimate is based on the Nelson Bay Iron Project Updated Resource Estimates for the DSO Deposit, 13 November 2013 by Simon Tear of H&S Consultants Pty Ltd.
-
Nelson Bay Iron Project Direct Shipping Ore Feasibility Study, 4 July 2012, by The Minserve Group Pty Ltd; and
-
Nelson Bay River Iron Project Direct Shipping Ore (DSO) JORC Reserves Statement Competent Person's Report, 24 October 2012, by Alwyn Hyde-Page of The Minserve Group Pty Ltd
-
The classification of the Ore Reserves into the confidence categories of Proven and Probable categories reflects the confidence of the ore resource categories in the Ore Resource Statement. Ore in each category is fully contained within the orebody mined within the pit shell with a selvage of lower grade ore encasing the high grade DSO ore.
Criteria for Classification
-
The Mineral Resource was converted to an Ore Reserve by upgrading resources completed in the Feasibility Study that included detailed mine design based on geotechnical input, a mining schedule that included loss and dilution and costing consistent with this level of study.
-
The DSO reserve estimate is based on 95% recovery of the high grade ore and 5% dilution with peripheral low grade material for the Measured and Indicated mineral resources, all of which are contained within the designed pit shell. Only the Iron % (Fe %) has been adjusted for loss and dilution with the other qualities shown based on their mineral resource values.
-
No Probable Ore Reserves have been derived from Measured Mineral Resources.
-
Mining Method & Assumptions
-
An opencut selective mining method was used to mine the ore in flitches using hydraulic excavators matched with articulated dump trucks. This was deemed to be the most appropriate method.
-
Geotechnical parameters for mine design were provided by Geonet Pty Ltd based on geotechnical drillholes and laboratory testing results. An audit of this work was done by Geotek Pty Ltd as part of the Nelson Bay River Mine Pit Stability Plan required as a condition of approval for mining. Grade control is an integral part of mining as described in the Nelson Bay Iron Project Direct Shipping Ore Feasibility Study and DSO JORC Reserve Statement of October 2012. No pre-production drilling is required.
-
Mining dilution of 5% with low grade ore was used.
-
Mining loss of 5% of the in situ ore was used.
-
Minimum mining widths were not applicable as internal waste was included with the ore in the model.
-
The Inferred Mineral Resources included in the pit, where appropriate, were mined in conjunction with the Measured and Indicated Resources as there is no

way that they can be differentiated separately in the block model. Where mined any Inferred Resource is included in the production schedule Processing Method & Assumptions
- The direct shipping ore requires no metallurgical process beyond crushing and screening to produce a product.
Basis of Cut off Grade
-
The geology mineral wireframe was designed to a 54% Fe cut-off as described in section 3. The resources and reserves for High Grade ore (HG) are reported from within the mineral shape with no grade cut-off.
-
A separate Low Grade (LG) ore selvage enclosing the high grade was modelled for ore below the 54% Fe cut-off .
Estimation Methodology
-
The Mineral Resource model used is that described in the Nelson Bay Iron Project Updated Resource Estimate for the DSO Deposit, 13 November 2013. All the Measured and Indicated Resources are contained within the DSO pit shell and these form the ore reserves.
-
Validation of the resource model provided by H&SC to Shree.
-
Economic modelling and analysis of surface constraints, mining leases and other modifying factors to determine the ultimate mining limits based on the Minserve 4 October 2012 Ore Reserve Estimate reports and the updated 2013 LIDAR surface coverage.
-
Adjustment of the existing pit layout and mining sequence to conform to the ultimate mining limits.
-
Reserves generation and Reserves reporting based on the updated November 2013 resource wireframe model imported by Shree into the SURPAC software system which was used to create mining block quantities and qualities used to develop the updated Production Schedule.
-
Material Modifying Factors
-
The accuracy and confidence of the Ore Reserves estimates are confined by the accuracy and confidence of the Mineral Resources estimates and are consistent with the selective mining method adopted and the grade control processes described. The type and size of mining equipment specified is matched to suit the geology of the mineralisation of the deposit.
Mr Yue Guan of Shree Minerals Limited carried out the modification of the mine design to accommodate updated surface topography and undertook the SURPAC software assessment of reserves scheduled within the modified Minserve (October 2012) pit shell design. Mr Alwyn Hyde-Page of Minserve supervised the preparation of this Ore Reserve report.

Based on current planning, the known DSO southern pit is scheduled to produce approximately 777,400t of DSO ROM product at an average grade of 56.7 %Fe over 19 months (note this includes Measured, Indicated and Inferred resources).
THE SOUTHERN DSO OXIDE RESOURCE DATA
Information material to understanding the Mineral Resource estimate Geology & Geological Interpretation • The Nelson Bay iron mineralisation comprises a steeply SW dipping mafic dyke intruded into steeply NE dipping siliciclastic sediments of the Proterozoic Rocky Cape Group. • The dyke has an unusual mineral assemblage of magnetite, siderite and grunerite and is reminiscent of skarn-type mineralogy. • The deposit displays a very distinct and discrete airborne magnetic anomaly. • Oxidation of the dyke by surface weathering has generated a distinct gossan within which occurs the high grade iron-rich DSO material • The geological interpretation for the DSO mineralisation is based on a combination of drillhole iron grades at a nominal cut off of 54%, drillhole logging and geological sense. • Mineralisation identifiable as red/yellow/brown oxidised material comprising gossan and ferruginous clay material; host rocks comprise grey slightly leached siliciclastics - Sampling & Sub sampling Techniques • A combination of RC and diamond drilling, some triple tube. Sampling consists of chips on 1m intervals and 1m cut half core. • Consistency of sampling method maintained • RC samples riffle split to 2-3kg and analysed by XRF • Diamond samples were sawn half core (HQ size). • Core sample intervals based on geological control. Drilling Techniques • The total number of holes on the deposit is 16 diamond and 37 reverse circulation. • Drill spacing was approximately 20-30m on section and 50m between sections. • Holes drilled at an angle on an even spaced grid; holes intersected mineralisation at a reasonably steep angle. Criteria for Classification • Classification of the estimates has been upgraded from the 2011 estimates to include Measured material. • The classification is based on the search parameters, geological understanding, the minimal changes from the previous estimates associated with the infill drilling, the compatibility of the diamond and RC drilling assay results and the QAQC outcomes for assays, sampling and drilling recoveries. • It is assumed that the deposit will be mined by an open pit method.

Sample Analysis Method
-
RC samples were sent to Burnie Research Laboratory (ALS) as weekly batches during the drilling program. Analysis was via the Iron Ore Procedure MEXRF21n, being the lithium borate fusion technique coupled with XRF. Elements analysed included Fe, Al2O3, P, S, SiO2, LOI plus a further 19 elements as part of a standard Iron Ore assay suite.
-
Earlier core samples sent to SGS in Perth
-
The QAQC programme comprised field duplicates and lab duplicates. No blind inserted standards or blank standards were used;
-
Second lab check (SGS in Perth) using the same analytical method consisted of 35 samples for a range of iron grades; no issues with accuracy of the original analysis noted.
Estimation Methodology
-
The mineral wireframe was used to generate 350 1m composites.
-
Ordinary Kriging was the modelling technique with an initial set of search parameters of 10m by 50m by 20m with the minimum number of data of 8 and 4 octants (Measured) increasing to a maximum set of 15m by 75m by 30m for a minimum number of 4 data and 2 octants (Inferred)
-
Modelled elements include iron, alumina, silica, sulphur, phosphorous and loss on ignition.
-
No top cutting applied;
-
Domaining used in the modelling has included a hard boundary delineating the high grade iron zone within the Gossan Unit; two orientation domains were used to account for the modest change in orientation of the mineral body
-
Maximum along strike extrapolation from nearest drillhole is 25m; width and depth is limited by the high grade mineral wireframe, generally <20m
-
• Tonnages are estimated on a dry weight basis default density of 3t/m[3] based 93 measurements of drillcore samples
-
Cut Off Grade including basis for the selected cut off grade • A review of sampling data indicated a population break around the 54% Fe mark; visual inspection appeared to confirm this feature
-
• A mineral wireframe was designed to this 54% Fe cut off with geological sense applied, a minor amount of lower grade samples were included as internal dilution
-
• The resource is reported from within the mineral shape with no grade cut off
-
Mining and metallurgical methods and parameters and other material modifying factors considered to data • An open pit mining scenario. • Peripheral dilution included • Small starter pit planned • Grade control procedures in place
The increase in the resource estimates is due to the use of a more accurate topographic surface, better definition of the resource around historical hole NBR6 and a modest south eastern extension.

Appendix B
– JORC Code, 2012 Edition Table 1 report Nelson Bay DSO Deposit 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, techniques or 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.
-
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, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.
Commentary
-
A combination of RC and diamond drilling, some triple tube. Sampling consists of chips on 1m intervals and 1m cut half core.
-
Holes drilled at an angle on an even spaced grid; holes intersected mineralisation at a reasonably steep angle.
-
Consistency of sampling method maintained
-
RC samples riffle split to 2-3kg and analysed by XRF
-
Diamond samples were sawn half core (HQ size).
-
Core sample intervals based on geological control.
-
Mineralisation identifiable as red/yellow/brown oxidised material comprising gossan and ferruginous clay material; host rocks comprise grey slightly leached siliciclastics
-
Sampling methods are to industry standard and are considered appropriate for deposit type
-
All oxidised intervals and a few metres extending into the footwall and hangingwall were sampled.

| The DSO South reserve estimate is based on the assumption | ||
