SUMMARY

Following completion of the 2014 field work campaign at Thunderbird in late October, a large resource update was delivered on schedule in December.

Significantly, new high grade resources were added in the up-dip region of the deposit and the proportion of the resource in the Indicated category was substantially increased. This sets a strong foundation for the Pre-feasibility Study which is on schedule for completion in Q1 2015.

Work programs have been designed for the Fraser Range nickel, Eneabba and McCalls HMS and Oxley potash projects, and are scheduled to be undertaken in H1 2015.

Exploration expenditure for the quarter is $3,950,000. Projected exploration expenditure for Q1 2015 is $1,100,000.

THUNDERBIRD MINERAL SANDS

Sheffield’s flagship Thunderbird mineral sands project is located near Derby in Western Australia (Figures 1 & 2).

The Thunderbird Scoping Study, released on 14 April 2014, showed the project has the potential to generate consistently strong cash margins from globally significant levels of production over an initial 32-year mine life.

Figure 2: Location of Thunderbird HMS project

On 12 December 2014 the Company announced an updated mineral resource of 3.205Bt @ 6.8% HM (Measured, Indicated and Inferred) for the Thunderbird deposit (Table 1, Appendix 1).

This compares with the previous March 2014 mineral resource of 2.62Bt @ 6.5% HM (Measured, Indicated & Inferred) at 3% HM cut-off (see Figure 3 and ASX release dated 19 March 2014).

1 Refer to Appendix 1 for further information.

2 The in-situ grade is determined by multiplying the percentage of HM by the percentage of each valuable heavy mineral within the heavy mineral assemblage.

3 Tonnes and grades have been rounded to reflect the relative uncertainty of the estimate, thus the sum of columns may not equal.

  • 4 -

The updated resource includes a coherent high grade zone of 1.080Bt @ 11.8% HM at 7.5% HM cut-off (Measured, Indicated and Inferred), containing 10.0Mt of zircon, 3.1Mt of high-titanium leucoxene, 2.8Mt of leucoxene and 36Mt of ilmenite.

The high in-situ valuable heavy mineral (VHM) grades for this zone of 0.92% zircon, 0.28% hightitanium leucoxene, 0.25% leucoxene and 3.3% ilmenite place Thunderbird in the top tier of mineral sands deposits globally.

The resource includes a significant new high grade component in the near-surface, up-dip region of the deposit (Figure 4). This component, comprising 95Mt @ 12.0% HM (Indicated) and 25Mt @ 12.2% HM (Inferred) (at 7.5% HM cut-off), is expected to further enhance the already robust project economics by adding more years of high grade feed to the front end of the mining schedule.

Figure 3: Thunderbird Resource Growth

Significantly, there has been a large increase in the Indicated Resource component (Figure 3). The Scoping Study excluded Inferred Resources, most of which have now been upgraded to the Indicated Resource category and will be incorporated into the Pre-feasibility Study.

The updated mineral resource is based on results from 509 aircore drill holes for 31,283m drilled by Sheffield between 2012 and 2014, including 68 new holes drilled during the 2014 program (refer to ASX releases dated 23 July; 17 September and 10 November 2014).

More results from the 2014 drilling program are anticipated during Q1 2015. These relate to 51 infill aircore drill holes and 20 sonic core drill holes in the up-dip portion of Thunderbird, and 61 regional exploration aircore drill holes.

Thunderbird Pre-feasibility

The Pre-feasibility Study is on schedule to be finalised in Q1 2015.

Work on the following activities is largely complete and reporting is in progress:

  • Bulk sample metallurgical testwork on full scale or scalable equipment;

  • Geotechnical investigations based on core from 20 sonic drill holes;

  • Mining studies;

  • Infrastructure and power studies;

  • Hydrogeological investigations.

Remaining work includes: tailings co-disposal testwork, process engineering design, product appraisal and marketing studies, optimization studies, mine scheduling and financial modelling.

Permitting

Sheffield continues to progress the permitting of the Thunderbird project, including mining lease application M04/459, which was lodged during the September 2014 quarter.

A polygonal native title claim, Mt Jowlaenga Polygon #2 – NNTT number WC2014/005, covering Application for Mining Lease 04/459 was formally entered on the National Native Title Tribunal register on 15 December 2014. The Company anticipates commencing negotiations with the claimants in the near future.

In December 2014, miscellaneous licences for access roads and a camp were lodged with DMP.

FRASER RANGE NICKEL

Four tenements were granted during the quarter (E28/2430, E28/2431, E28/2323 and E63/1696). Sheffield now has 12 granted tenements and 4 tenement applications in the Fraser Range and the adjacent Tropicana Belt with a combined area of 2,300km[2] (Figure 6).

  • 7 -

Red Bull Nickel

The main exploration target at Red Bull is an 8km long Ni-Cu-Co anomalous trend in a layered mafic-ultramafic sequence in the northern project area. Three substantial nickel targets have been outlined from aircore drilling, including intervals of up to 5m @ 0.73% Ni with anomalous Cu, Co and PGEs (refer to ASX release of 11 February 2014). Collectively, these are referred to as the “Northern Targets”.

Moving loop EM surveys have been designed for the Northern Targets region and are scheduled for completion during Q1 2015.

Big Bullocks Nickel

The Big Bullocks project (E39/1733) is located in the northeast sector of the Fraser Range (Figure 6) and straddles the major regional gravity ridge associated with the Fraser Complex. During the quarter, a bedrock geological interpretation was completed using available datasets, including recently acquired 100m-spaced aeromagnetic survey data. Magnetic lows, representing possible ultramafic intrusions, were identified and will be prioritised for initial aircore drilling during Q1 2015.

MCCALLS HEAVY MINERAL SANDS

The McCalls project, located 110km north of Perth, has an Inferred Resource of 4.4Bt @ 1.2% HM containing 53Mt of HM (Appendix 1). Of this, 43 million tonnes is chloride grade ilmenite (66% TiO2) ranking McCalls as one of the largest undeveloped chloride ilmenite deposits in the world. The deposit also contains approximately 3.5 million tonnes of zircon and 1 million tonnes of rutile.

A mineral resource update for McCalls is scheduled for completion during Q1 2015.

The Mindarra Springs HMS prospect, located 20km to the south of McCalls, has an Exploration Target[1] of 1.7-2.2Bt at 1.4%-1.6% HM (refer to September 2014 Quarterly Report for full details). A short aircore drilling program to confirm the grade and mineral assemblage is scheduled for H1 2015.

ENEABBA HEAVY MINERAL SANDS

The Eneabba project comprises five mineral sands deposits: West Mine North, Ellengail, Yandanooka, Durack and Drummond Crossing with combined resources of 6.76Mt of HM (Appendix 1). Sheffield’s strategy is to evaluate these deposits with a view to developing a sequential mining operation, whilst actively exploring the region for further deposits.

An aircore drilling program has been designed for initial testing of several dunal-style HMS targets along the Gingin scarp to the east and north of Eneabba. This drilling is scheduled for H1 2015.

OXLEY POTASH

The Oxley potash project is located near Morawa in Western Australia’s Mid-west region. Oxley has an unconventional, hard rock style of potash mineralisation, hosted by a series of ultrapotassic microsyenite lavas, which typically contain over 90% sanidine (potash) feldspar. Sheffield controls the entire 32km strike extent of the prospective units within the northern Moora Basin.

Sheffield’s maiden drilling programme at Oxley returned thick, high grade potash intervals averaging 8.4% K2O over 36m width with higher grade intervals averaging 9.9% K2O over 15m width. (Refer to ASX release of 19 July 2013 for full details).

During the quarter, regional geological reconnaissance sampling and mapping was undertaken to outline the full extent of the Oxley microsyenite lavas. Metallurgical testwork and marketing studies have been scheduled for H1 2015.

1 Sheffield Resources has not yet reported any Mineral Resources for Mindarra Springs and any discussion in relation to the potential quantity of the targets is conceptual in nature. There has been insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource.

OTHER

No work was undertaken on the Pilbara Iron and Moora Talc projects during the quarter.

CASH POSITION

As at 31 December 2014, the Company had cash reserves of approximately $4.7 million.

During Q1 2015, the Company may receive approximately $1.5 million from its 2014 Research and Development tax return.

During the quarter $60,000 was raised from the exercise of options.

SCOPING STUDY

The Scoping Study referred to in this report is based on low-level technical and economic assessments, and is insufficient to support estimation of Ore Reserves or to provide assurance of an economic development case at this stage, or to provide certainty that the conclusions of the Scoping Study will be realised.

FORWARD LOOKING AND EXPLORATION TARGET STATEMENTS

Some statements in this report regarding estimates or future events are forward-looking statements. They involve risk and uncertainties that could cause actual results to differ from estimated results. Forward-looking statements include, but are not limited to, statements concerning the Company’s exploration programme, outlook, target sizes and mineralised material estimates. They include statements preceded by words such as “anticipated”, “expected”, “target”, “scheduled”, “intends”, “potential”, “prospective” and similar expressions.

The terms “Target” and “Exploration Target”, where used in this report, should not be misunderstood or misconstrued as an estimate of Mineral Resources and Reserves as defined by the JORC Code 2012, and therefore the terms have not been used in this context. Exploration Targets are conceptual in nature and it is uncertain if further exploration or feasibility study will result in the determination of a Mineral Resource or Reserve.

* All tonnages and grades have been rounded to reflect the relative uncertainty of the estimate and maintain consistency throughout the table, thus sum of columns may not equal. 1 See the compliance statements in this report for important information relating to the reporting of these Mineral Resources. 2 The Mineral Assemblage is represented as the percentage of the Heavy Mineral (HM) component of the deposit, determined by QEMSCAN for Eneabba & McCalls, with TiO2 minerals defined according to the following ranges: Rutile >95% TiO2; Leucoxene 85-95% TiO2; Ilmenite <55-85% TiO2; for Dampier the mineral assemblage was determined by screening and magnetic separation. Magnetic fractions were analysed by QEMSCAN for mineral determination as follows: Ilmenite: 40-70% TiO2 >90% Liberation; Leucoxene: 70-94% TiO2 >90% Liberation; High Titanium Leucoxene (HiTi Leucoxene): >94% TiO2 >90% Liberation; and Zircon: 66.7% ZrO2+HfO2 >90% Liberation. Non-magnetic fractions were submitted for XRF analysis and minerals determined as follows: Zircon: ZrO2+HfO2/0.667 and High Titanium Leucoxene (HiTi Leucoxene): TiO2/0.94.[3] West Mine North, Drummond Crossing, Durack and McCalls deposits are reported below 35% slimes cut-off.
