ASX and Media Release
28 November 2012
HIGH ORDER VTEM ANOMALIES IDENTIFIED AT RED BULL
KEY POINTS
-
Numerous electromagnetic anomalies identified from initial Red Bull VTEM survey
-
4 high order anomalies represent immediate targets for follow up, 3 of these have coincident magnetic anomalies
-
Infill VTEM lines currently being flown over the 4 high order anomalies

Sheffield Resources (“Sheffield”, “the Company”) (ASX:SFX) today announced the identification of four high order anomalies from the first pass VTEM airborne electromagnetic (EM) survey undertaken at its Red Bull Project. Red Bull is located within 20km of Sirius Resources NL’s (ASX:SIR) recent Nova nickel-copper discovery in the newly identified Fraser Range Nickel Province in Western Australia (Figure 3).
Geophysical consultants, Southern Geoscience Consultants have identified four high order EM anomalies (RB_VA1 to 4 – Figures 1 & 2), three of which show correlation with magnetic anomalies. Over ten second order VTEM anomalies have been defined, which will require further detailed assessment of the data and infill results to rank them accordingly (Figure 1).
A program of infill VTEM surveying is underway to reduce the line spacing over these anomalies to 100m.
Managing Director, Bruce McQuitty said the early results provide Sheffield with immediate targets for follow up work.
“While it is early days, to have four highorder anomalies generated from the first VTEM survey at Red Bull is an exciting result, and provides an immediate focus for ground based work.”
“Follow-up reconnaissance of these targets will begin immediately.”

“Interpretation of the survey data is ongoing and is likely to generate further targets.”

Sheffield engaged Southern Geoscience Consultants (SGC) to design and manage the programme, and provide data processing and interpretation services. Preliminary comments from SGC on the priority anomalies identified to date (Figure 2) are as follows:
-
RB_VA1 – Strong, high amplitude VTEM anomaly apparent over two main survey lines, strike ~200-400m. Source is likely to be at shallow depth <100m. Clear relationship to a local magnetic anomaly.
-
RB_VA2 – Moderate-Strong VTEM anomaly apparent over two main survey lines, strike ~200-400m. Source is likely to be at shallow-moderate depth ~100m+. Clear relationship to a local magnetic anomaly.
-
RB_VA3 – Moderate-Strong, low amplitude VTEM anomaly apparent over two main survey lines, strike ~200-400m. Source is likely to be at moderate-deep level >>100m. Clear relationship to the margin of a local circular magnetic anomaly/ potential intrusive body.
-
RB_VA4 – Moderate-Strong VTEM anomaly apparent over 3-4 main survey lines, strike >400m. Source is likely to be at moderate depth level ~100m+. Appears to be situated along the margin of a broad, deep seated magnetic body.
The additional lower-order anomaly shown in area (RB_VA5) is a possible localised bedrock anomaly; infill surveying will assist confirming whether this is of interest or a second order target.
Areas of high conductivity, likely to be related to palaeodrainage features are apparent in the data (Figure 1). In these areas the VTEM effectiveness is limited, however ground based EM methods will be considered to survey areas of geological interest as a second phase.
VTEM Survey details
The 144km[2] VTEM survey targeted prospective mafic and ultramafic sequences of the Fraser Complex beneath shallow transported cover in the northern half of tenement E69/3052 (which is pending grant). Sheffield initially planned surveying at 100m line-spacing over the northern half of the target area, and 200m line spacing in the south for a total 1,112.8 line km. Following identification of priority anomalies in the south, an additional 90 line km of infill lines were designed and are currently being surveyed. Only preliminary datasets have been received to date.

ABOUT SHEFFIELD RESOURCES
Sheffield Resources Limited ( Sheffield ) is a rapidly emerging heavy mineral sands (HMS) company.
ASX Code – SFX Market Cap @ 48cps - $47.2m Issued shares – 98.4m Cash - $7.3m (at 30/9/2012)
The Company has over 6,000km[2] of highly prospective tenure, all situated within the state of Western Australia.
HEAVY MINERAL SANDS
The Dampier project, located near Derby in WA’s Kimberley region, contains the large, high grade zircon-rich Thunderbird HMS deposit.
The Eneabba project comprises multiple HMS deposits and is located near Eneabba approximately 140km south of the port of Geraldton in WA’s Mid-West region.
Sheffield is also evaluating the large McCalls chloride ilmenite project, located 110km to the north of Perth.
NICKEL-COPPER
Sheffield’s 525km[2] Red Bull project is located in the highly prospective Fraser Complex within 20km of Sirius Resources NL’s (ASX:SIR) Nova Ni-Cu discovery.
IRON
Sheffield has identified iron mineralisation on three of its tenements in the Pilbara iron ore province. Thick hematite mineralisation was intersected in first pass RC drilling at the Three Pools project, 20km north of Newman.
TALC
Sheffield’s large Moora Talc Belt project contains numerous talc occurrences and is located near Imerys’ long-life Three Springs talc mine in WA’s Mid-West region. The Company is targeting high purity talc, similar to that produced from the simple quarrying operation at Three Springs.
