ASX and Media Release

23 July, 2015

NEXT GENERATION OF MINERAL SANDS DISCOVERIES AT ENEABBA

KEY POINTS

  • Four new near-surface, dunal HMS discoveries from initial aircore drilling program

  • High value mineral assemblage: up to 36% combined rutile and zircon

  • Discoveries occur east of the Gingin Scarp, away from the historic focus of mineral sands mining and exploration in the Eneabba district

  • Sheffield’s existing resources at Eneabba plus new discoveries may support a standalone operation

Sheffield Resources Limited (“Sheffield” “the Company”) (ASX:SFX) today announced the discovery of four new mineral sands prospects from first-pass aircore drilling at its 100% owned Eneabba Mineral Sands Project in Western Australia’s Mid-West region (Figure 2).

The dunal deposits, named Robbs Cross, Thomson, Ding Road and Mt Adams, occur to the east of the Gingin Scarp, a topographic feature representing a former coastal cliff. Historically, most mineral sands mining and exploration at Eneabba has targeted strandlines located to the west of this feature (Figure 2).

Significant results include:

Robbs Cross

  • 21m @ 1.96% HM from 3m (RCAC001), including 9m @ 2.76% HM from 12m

  • 19.5m @ 1.98% HM from 3m (RCAC005), including 9m @ 2.58% HM from 10.5m

  • mineral assemblage: 12.5% rutile, 14.7% zircon, 4.1% leucoxene, 47% ilmenite

Ding Road

  • 10.5m @ 2.35% HM from 0m (DCAC153), including 6m @ 3.02% HM from 3m

  • 9m @ 2.70% HM from 0m (DCAC154),including 7.5m @ 2.97% HM from 0m

  • mineral assemblage: 15.4% rutile, 20.3% zircon, 3.8% leucoxene, 44% ilmenite

Thomsons

  • 22.5m @ 2.16% HM from 0m (TMAC016), including 4.5m @ 4.37% HM from 18m

  • 16.5m @ 1.83% HM from 0m (TMAC005), including 7.5m @ 2.22% HM from 6m

  • mineral assemblage: 12.3% rutile, 15.1% zircon, 3.6% leucoxene, 50% ilmenite

Mt Adams

  • 10.5m @ 2.11% HM from 0m (MAAC017), including 7.5m @ 2.48% HM from 1.5m

  • mineral assemblage: 10.4% rutile, 13% zircon, 2.1% leucoxene, 57% ilmenite

(refer to Tables 2 and 3, Figures 2, 3 and 4, and Appendix 2 for full details)

Sheffield’s Managing Director Bruce McQuitty said the four discoveries represented an exciting new frontier for exploration in the world class Eneabba mining district.

“The dunal style of heavy mineral deposit we are targeting has many favourable characteristics for mining, including a high value mineral assemblage and favourable deposit geometry with little or no overburden,” he said.

“We are confident the region will yield further discoveries, enabling us to build on our existing high grade Eneabba Resource base of 4.5Mt of contained valuable heavy mineral.”

The current high grade resource at Sheffield’s Eneabba Project comprises 172Mt at 3.0% HM (Table 1 and Appendix 1) in three dunal deposits (Yandanooka, Durack and Drummond Crossing), one strandline deposit (West Mine North) and one combined dunal and strandline deposit (Ellengail). Of these, the Drummond Crossing resource, with its combined zircon and rutile assemblage of 24%, is most similar in setting and style to the dunal prospects outlined by recent drilling. The four recent discoveries have combined zircon and rutile assemblages of between 23% and 36%.

The dunal deposits of the Eneabba region are typically rich in zircon and rutile and the ilmenite is generally high grade (>60% TiO2) and suitable as feedstock for the chloride pigment process or as synthetic rutile feedstock. The deposits are broad, up to 20m thick, have little or no overburden and sit above the water table – factors which contribute to simple, low-cost mining.

This type of deposit (dunal) has received little exploration attention in the region, despite the most recent mining operations at Eneabba being based on them. An example is Iluka Resources’ Twin Hills deposit, which was mined during 2012 and early 2013. Prior to mining, Twin Hills had a probable reserve of 19.9Mt @ 3.2% HM, and assemblage of 11% zircon, 10% rutile and 55% ilmenite[1] .

Another example of a dunal deposit currently in development is Matilda Zircon’s Keysbrook deposit located in the South Perth Basin, which has a proven and probable reserve of 26.0Mt @ 2.6% HM, and assemblage of 14.6% zircon, 27.8% leucoxene 70 and 46.6% leucoxene 88[2] l. These deposits are an attractive development proposition due to their high value mineral assemblage and low mining costs.

Prospect Details

The results reported above relate to a low cost program of 92 shallow aircore drill holes totalling 2,664m undertaken in April 2015, utilising existing tracks for access on vacant crown land. The drilling targeted anomalous heavy mineral identified from surface sampling (see ASX release dated 30 October, 2013).

An additional 6 aircore holes totalling 219m were drilled at the Mindarra Springs prospect primarily to collect bulk sample for metallurgical test work.

A full listing of drill hole details, significant intervals and mineral assemblage data is included as Tables 2 and 3.

Robbs Cross

Robbs Cross is about 5km to the northeast of Sheffield’s Drummond Crossing resource (52.2Mt @ 2.1% HM Indicated and Inferred – refer to Appendix 1). Surface sampling identified a 2.5km x 1km anomaly of between 0.7% and 2.0% HM on the eastern flank of a low hill. The anomaly was drilled with 18 aircore holes spaced 200m apart on 2 lines. Of these, 15 holes returned mineralisation >0.9% HM over an area 1.5km x 1.4km, between 3m and 21m thickness (average 13m), with 0m to 9m of barren cover (average 4m). Within this lower grade mineralisation is a coherent higher grade zone (>2% HM) up to 9m thick over an area of 1km x 600m. The mineral assemblage is 12.5% rutile, 14.7% zircon, 4.1% leucoxene, 47% ilmenite.

Mineralisation remains open to the east, west and south. Additional drilling on optimally oriented transects is required to advance Robbs Cross, which has the potential to yield a significant deposit.

Thomsons

Thomsons is located 12km east of Sheffield’s West Mine North deposit and 2.6km south of Iluka Resources’ Ocean Hill deposit. Surface sampling identified a 3.7km long by 0.25km to 1.0km wide anomaly between 0.7% and 4.8% HM. The anomaly was investigated with 25 holes drilled at about 200m spacing, most along an existing north-south access track. From this drilling two areas of mineralisation were identified, one comprising patchy mineralisation over a 2.5km x 1.5km area with upper (near-surface) and deeper mineralised zones. Mineralisation in this area is mostly low grade with the best interval 22.5m @ 2.16% HM from surface in hole TMAC016. The other is defined by a single hole at the end of the drilled line: 24m @ 1.64% HM from surface in hole TMAC013. The mineral assemblage averages 12.3% rutile, 15.1% zircon, 3.6% leucoxene, 50% ilmenite.

Additional drilling is required to better define mineralisation at Thomsons, however even at this early stage with only very limited drilling, there is clear potential to extend the mineralisation.

Ding Road

Ding Road is located 1.8km east of Sheffield’s Drummond Crossing resource. Previous scout drilling and surface sampling by Sheffield returned values up to 2.9% HM, confirmed by significant mineralisation in a single line of 200m-spaced aircore holes drilled in 2012 (see September 2012 Quarterly report dated 18 October, 2012). An additional 24 aircore holes were drilled at Ding Road, both infilling, and testing for extensions to existing mineralisation to the north and west.

Results indicate the mineralisation extends a further 600m to the north, is closed off to the west, but remains open to the east. With the additional drilling, the high grade component (>2% HM) at Ding Road now extends for 1km, is up to 7.5m thick, and has between 0m and 7.5m of cover. Significantly, Ding Road has an excellent mineral assemblage with over 35% combined rutile and zircon: 15.4% rutile, 20.3% zircon, 3.8% leucoxene, 44% ilmenite.

Additional drilling is required to test the extent of this mineralisation to the east of Ding Road.

Mt Adams

Mt Adams is immediately east of Tronox’s Dongara heavy mineral sands project. Surface sampling by Sheffield identified two zones of coherent mineralisation between 0.7% and 2.05% HM. The larger northern zone has the approximate dimensions of 1.6km by 1.2km and the smaller southern zone has the dimensions of 0.8km by 0.6km.

Both anomalies were investigated with a total of 22 aircore holes drilled at 240m spacing along existing tracks. Of these, 8 holes returned significant intervals with the best being 10.5m @ 2.11% HM from 0m in hole MAAC017, including 7.5m @ 2.48% HM from 1.5m. At 0.9% HM cut-off the mineralisation extends over an area of 1.7km x 850m, is between 3m and 10.5m in thickness (average 6m) and has between 0m and 7.5m (average 2.7m) of barren cover. The mineral assemblage is 10.4% rutile, 13% zircon, 2.1% leucoxene, 57% ilmenite.

Mineralisation at Mt Adams is open in all directions. Additional drilling is required to fully test the extent of mineralisation, with the current results suggesting excellent potential to define a nearsurface HMS deposit.

Mindarra Springs

Mindarra Springs is located 20km to the south of Sheffield McCalls HMS resource. BHP explored Mindarra Springs for mineral sands in the mid-1990’s and drilled approximately 150 aircore drill holes through the area. Sheffield has previously announced an Exploration Target[3] based on this drilling of approximately 1.7-2.2Bt at 1.4%-1.6% HM (refer to Sheffield’s September 2014 Quarterly Report, dated 28 October 2014 for details).

3 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. Figures have been rounded to reflect the implied level of accuracy.

A single line of six holes were drilled at 500m spacing along an existing road for the primary purpose of collecting sample for ilmenite characterisation test work. The mineralised intervals and assemblage data returned from the drilling are within the ranges predicted, confirming the quality of the historic BHP drilling. For example the best interval of 16.5m @ 2.17% HM from 10.5m in hole MSAC005, including 9m @ 2.78% HM from 16.5m. The mineral assemblage comprises 3.9% rutile, 3.8% zircon, 2.3% leucoxene and 81% ilmenite (total 91% VHM).

Further Work

The results reported in this announcement are from initial, first-pass drilling which utilised existing tracks for access and placement of drill holes. This work resulted in a 100% success rate with significant mineralisation identified, and additional drilling required at each prospect.

Sheffield has identified a number of additional targets similar in setting to those tested by this drilling program, and will prioritise additional work in the region to investigate these opportunities.

Appendix 2: JORC (2012) Table 1 Report (23 July, 2015 Eneabba dunal aircore drilling results)

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

Criteria JORC Code explanation Commentary
Sampling
techniques

Nature and quality of sampling (eg cut
channels, random chips, 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.

NQ diameter aircore drilling used to
collect 2-3kg samples at 1.5m intervals
down-hole.

Mineral Sands Industry-standard drilling
technique.
Drilling
techniques

Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast, auger,
Bangka, sonic, etc) and details (eg core
diameter, triple or standard tube, depth of
diamond tails, face-sampling bit or other
type, whether core is oriented and if so, by
what method, etc).

Aircore system NQ diameter holes.

Blade drill bit used for all drilling

Aircore system used as an industry
standard for HMS deposits.
Drill sample
recovery

Method of recording and assessing core
and chip sample recoveries and results
assessed.

Measures taken to maximise sample
recovery and ensure representative
nature of the samples.

Whether a relationship exists between
sample recovery and grade and whether
sample bias may have occurred due to
preferential loss/gain of fine/coarse
material.

Sample quality (including wet vs. dry and
qualitative recovery) is logged at the drill
site.

Orientation process undertaken at the
beginning of program to set up sampling
system to collect 2-3kg sub-sample from
1.5m intervals.

Sample weight recorded at laboratory

Drill system is optimised for HMS.

Duplicate samples are collected at the
drill site (see below) to enable analysis of
data precision.

The sample quality is considered
appropriate, for example, to establish
context of exploration results and support
Mineral Resource estimation.
Logging
Whether core and chip samples have
been geologically and geotechnically
logged to a level of detail to support
appropriate Mineral Resource estimation,
mining studies and metallurgical studies.

Whether logging is qualitative or
quantitative in nature. Core (or costean,
_channel, etc) photography. _

Every drill sample is washed and panned,
then geologically logged on-site in 1.5m
intervals, recording primary, secondary
and oversize lithology, qualitative
hardness, grainsize, rounding, sorting, and
washability, visual estimates of HM%, SL%
and OS%, and depth to water table.

The entire length of the drill hole is logged;
  • 20 -
Criteria JORC Code explanation Commentary

The total length and percentage of the
relevant intersections logged.
minimum (nominal) interval length is 1.5m.

Logging is suitable such that
interpretations of grade and deposit
geology can be used, for example, to
establish context of exploration results and
support Mineral Resource estimation.
Sub-sampling
techniques
and sample
preparation

If core, whether cut or sawn and whether
quarter, half or all core taken.

If non-core, whether riffled, tube sampled,
rotary split, etc and whether sampled wet
or dry.

For all sample types, the nature, quality
and appropriateness of the sample
preparation technique.

Quality control procedures adopted for all
sub-sampling stages to maximise
representivity of samples.

Measures taken to ensure that the
sampling is representative of the in situ
material collected, including for instance
results for field duplicate/second-half
sampling.

Whether sample sizes are appropriate to
the grain size of the material being
sampled.
HM%, SL% OS% Determination
Drill Site

2-3kg sample collected at 1.5m intervals in
numbered bags at the drill site via rotary
splitter at cyclone discharge point.

Duplicate samples (field duplicates)
collected at drill site 1 in every 40 samples.

Reference blank material samples inserted
1 each in every 40 samples.

Sample submitted to external laboratory
for heavy liquid separation (HLS)
determination of weight per cent heavy
mineral (HM), Slimes (SL) and Oversize
(OS).
Laboratory

2-3kg drill sample sub-split via rotary splitter
to approx. 200g for analysis.

HM, SL and OS calculated as percentage
of total sample weight.

Laboratory repeat and standard are
inserted 1 in every 40 samples.
All

Spacing of duplicate, standard, blank and
lab repeat samples are designed to
identify sample misplacement or
misallocation during sample collection
and laboratory analysis.

Sample representivity and data precision
has been determined as acceptable
through analysis of results from field
duplicate samples and laboratory repeats.

Visual estimates of HM, Slimes and OS
logged at the drill site are compared
against laboratory results to identify any
major errors.

Analysis of duplicates show the data has
acceptable precision, indicating sampling
techniques are appropriate for the deposit
style.

Techniques are considered appropriate
for use in public reporting of Exploration
Results.
HM Assemblage Determination

Heavy Mineral Concentrate (HMC) from
individual samples is combined according
to HM grade and weight into (nominal)
25g – 50g composite samples for HM
assemblage determination.

Weighed HMC is split via a micro-riffle to
ensure HM%, SL% and OS% of the final
composite sample can be correctly
calculated.

Resultant data is considered to be of
suitable quality for the reporting of
Exploration Results.
  • 21 -
Criteria JORC Code explanation Commentary
Quality of
assay data
and
laboratory
tests

The nature, quality and appropriateness of
the assaying and laboratory procedures
used and whether the technique is
considered partial or total.

For geophysical tools, spectrometers,
handheld XRF instruments, etc, the
parameters used in determining the
analysis including instrument make and
model, reading times, calibrations factors
applied and their derivation, etc.

Nature of quality control procedures
adopted (eg standards, blanks,
duplicates, external laboratory checks)
and whether acceptable levels of
accuracy (ie lack of bias) and precision
have been established.
HM%, SL% OS% Determination

Assay and laboratory procedures are
industry standard for HMS, although
laboratories’ methods and heavy liquid
composition vary slightly. TBE (2.96g/ml) is
used for these results.

Method produces a total grade as weight
per cent of the initial sample.

Method does not determine the relative
amounts of valuable (saleable or
marketable) and non-valuable heavy
mineral species.

QAQC sample frequency is described
above. Blank material used is
commercially available builder’s sand.

Reference standards and blanks are
examined for performance over time and
within laboratory batches. Batches or sub-
batches are re-analysed if unacceptable
QAQC data are returned.

Analysis of reference standards, blanks
and laboratory repeats show the data to
be of acceptable accuracy and precision
for use in public reporting of Exploration
Results.
HM Assemblage Determination

HM assemblage determination was by
QEMSCAN™.

This method is considered an industry
standard, typically optimised according to
the HM characteristics of individual
deposits.

The QEMSCAN™ process uses observed
mass and chemistry to classify particles
according to their average chemistry, and
then report mineral abundance by %
mass.

For TiO2minerals specific breakpoints are
used to distinguish between rutile (>95%
TiO2), leucoxene (85-95% TiO2) and
ilmenite (<55-85% TiO2). These breakpoints
are chosen to reflect mineral assemblage
data defined by previous workers in the
region, and provide a consistent base for
comparison between prospects and
Mineral Resources.

Reference material was not used, the
method design and comparison to visual
observation is considered sufficient to
establish acceptable accuracy of the
data for the reporting of Exploration
Results.
Verification
of sampling
and assaying

The verification of significant intersections
by either independent or alternative
company personnel.

The use of twinned holes.

Documentation of primary data, data
entry procedures, data verification, data
storage (physical and electronic)
protocols.

Discuss any adjustment to assay data.

Significant intervals are reviewed by senior
Sheffield personnel prior to release.

Data is logged electronically using
“validation at point of entry” systems prior
to storage in the Company’s drill hole
database, which is managed by
Company personnel and an external
consultancy.

Documentation related to data custody
and validation are maintained on the
Company’s’ server.

Location of
data points

Accuracy and quality of surveys used to
locate drill holes (collar and down-hole
surveys), trenches, mine workings and
other locations used in Mineral Resource
estimation.

Specification of the grid system used.

Quality and adequacy of topographic
control.

Drill hole collar locations were determined
by handheld GPS with expected
accuracy of +/- 15m horizontal.

RL was determined by projection to a DTM
models created from Landgate spot
height data.

Coordinates are referenced to the Map
Grid of Australia (MGA) zone 50 on the
Geographic Datum of Australia (GDA94),
RL are AHD.

The quality and accuracy of the
topographic control is considered
sufficient for the reporting of Exploration
Results.
Data spacing
and
distribution

Data spacing for reporting of Exploration
Results.

Whether the data spacing and distribution
is sufficient to establish the degree of
geological and grade continuity
appropriate for the Mineral Resource and
Ore Reserve estimation procedure(s) and
classifications applied.

Whether sample compositing has been
applied.

See body of announcement for drill hole
spacing.

Significant intervals are reported as
indicated in the relevant table(s) in the
body of the announcement.

Details of samples composited for mineral
assemblage determination are included in
the body of the announcement.
Orientation
of data in
relation to
geological
structure

Whether the orientation of sampling
achieves unbiased sampling of possible
structures and the extent to which this is
known, considering the deposit type.

If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to
have introduced a sampling bias, this
should be assessed and reported if
material.

Mineralisation is generally flat-lying,
vertical drill holes therefore approximate
true thickness and perpendicular
intersection of mineralisation.
Sample
security

The measures taken to ensure sample
security.

Sample security is not considered a
significant risk given the location of the
deposit and bulk nature of mineralisation.

Nevertheless, the use of recognised
transport providers, and sample dispatch
procedures directly from the field to the
laboratory are considered sufficient to
ensure appropriate sample security.
Audits or
reviews

The results of any audits or reviews of
sampling techniques and data.

No formal external audits or review of
sample techniques or data have been
conducted.

Audits are not considered necessary at this
stage, Industry-standard methods are
beingemployed.

Exploration
done by
other parties

Acknowledgment and appraisal of
exploration by other parties.

The Mindarra Springs area was explored
by BHP between 1991 and 1996. BHP
completed 410 holes for 13,556m drilled
over the project area, about 150 of which
cover Mindarra Spings – refer to the body
of the announcement for further detail.
Geology
Deposit type, geological setting and style
of mineralisation.

The Eneabba Project forms part of the
Swan Coastal Plain bounded to the east
by the Gingin Scarp within the Northern
Perth Basin. The Gingin Scarp is a remnant
feature of the marine incursion which
resulted in the reworking of older rocks
and ended in the deposition of heavy
mineral sand enriched beach placers
within Cainozoic sediments. Heavy
mineral sand mining is prolific within the
Swan Coastal Plain sediments.

The prospects drilled are in newly
interpreted heavy mineral trap sites
located to the north of Eneabba and to
east of the Gingin Scarp and adjacent to
westerly to south-westerly trending paleo-
drainage.

Mindarra Spring consists of unconsolidated
Cainozoic littoral sands, gravel and clays
which cover the Cretaceous sediments of
the Dandaragan trough. The Dandaragan
trough is fault bound to the west by the
Eneabba Fault System and to the east by
the Darling Fault; which forms the
topographic expression of the Darling
Fault separating the Perth Basin from the
Archaean Yilgarn craton.

this table, and in the body of the
announcement.

announcement show the location of and
distribution of drill holes.
Data
aggregation
methods

In reporting Exploration Results, weighting
averaging techniques, maximum and/or
minimum grade truncations (e.g. cutting
of high grades) and cut-off grades are
usually Material and should be stated.

Where aggregate intercepts incorporate
short lengths of high grade results and
longer lengths of low grade results, the
procedure used for such aggregation
should be stated and some typical
examples of such aggregations should be
shown in detail.

The assumptions used for any reporting of
metal equivalent values should be clearly
stated.

Criteria for calculating significant intervals
are included in the body of the
announcement. Minimum widths,
maximum internal waste intervals and cut-
off grades have been selected to most-
appropriately represent the
mineralisation, taking into account the
early-stage, reconnaissance nature of the
drill program. No “high” or “top-cuts” are
applied. Higher-grade components of
significant intervals are detailed in Table 1
preceded by the term_“including”._
Relationship
between
mineralisation
widths and
intercept
lengths

These relationships are particularly
important in the reporting of Exploration
Results.

If the geometry of the mineralisation with
respect to the drill hole angle is known, its
nature should be reported.

If it is not known and only the down hole
lengths are reported, there should be a
clear statement to this effect (e.g. ‘down
_hole length, true width not known’). _

Mineralisation is generally flat-lying,
vertical drill holes therefore approximate
true thickness.
Diagrams
Appropriate maps and sections (with
scales) and tabulations of intercepts
should be included for any significant
discovery being reported These should
include, but not be limited to a plan view
of drill hole collar locations and
appropriate sectional views.

See body of announcement.
Balanced
reporting

Where comprehensive reporting of all
Exploration Results is not practicable,
representative reporting of both low and
high grades and/or widths should be
practiced to avoid misleading reporting of
Exploration Results.

All current drill hole results are reported in
this announcement. Where results do not
meet the criteria of significant interval
these are reported in Table 1 as “no
significant interval”.

All information considered material to the
reader’s understanding of the exploration
results have been reported.
