COMPELLING NEW DRILL TARGET IDENTIFIED FROM GROUND EM SURVEY AT RED BULL NICKEL PROJECT

KEY POINTS

  • Coincident bedrock conductor and nickel geochemical target identified at Stud prospect:

  • Modelled bedrock conductor of 500m x 500m, depth to top 150-200m

  • Significant nickel anomalism in shallow aircore drill holes coincident with up-dip projection of conductor: e.g. 12m @ 0.32% Ni from 37m (REAC272)

  • 1km trend of IP anomalism (possible disseminated sulphide source) extends south from conductor and coincides with >0.1% Ni anomalism in aircore drill holes, e.g. 5m @ 0.73% Ni from 33m in hole REAC240

  • Traces of nickel and copper sulphides in end-of-hole aircore samples

  • Scout aircore drilling results enhance prospectivity of Big Bullocks project in Northern Fraser Range

Sheffield Resources Limited (“Sheffield” “the Company”) (ASX:SFX) today announced the identification of a new, high-priority Ni-Cu drill target following completion of high-powered, moving loop EM surveys at its 100% owned Red Bull Nickel Project, located in the Fraser Range region of Western Australia (Figure 3).

Red Bull MLTEM

The recently completed systematic high-powered MLTEM survey covered the Northern Targets region at Red Bull, where previous aircore drilling and soil sampling outlined several areas of NiCu-Co anomalism along an 8km strike length of a folded and faulted mafic/ultramafic complex (see ASX release dated 18 February 2015).

The most significant result from the survey is the discovery of a new bedrock conductor of moderate intensity located beneath significant Ni-Cu anomalism in shallow aircore drill holes at the Stud prospect. Stud was originally defined from two phases of exploration aircore drilling undertaken by Sheffield in the second half of 2013, outlining a coherent anomaly of >0.2% maximum Ni-in-hole over a strike length of 1.8km.

Southern Geoscience Consultants (SGC) have modelled the source of the conductive anomaly as large (~500m x 500m), striking NNE-SSW, with a vertical to 85 degree plunge to the ESE and a depth to top of ~150-200m (Figure 1).

Significant results from aircore drilling in the area immediately up-plunge from the modelled bedrock conductor include:

  • 22m @ 0.39% Ni , 138ppm Cu, 272ppm Co, 7ppb Pt, from 32m (REAC240) including 5m @ 0.73% Ni , 168ppm Cu, 466ppm Co from 33m

  • 12m @ 0.32% Ni , 204ppm Cu, 337ppm Co, 8ppb Pt from 37m (REAC272)

  • 8m @ 0.15% Ni , 400ppm Cu, 261ppm Co, 14.5ppb Pd, 14.5ppb Pt from 22m (REAC250)

  • 12m @ 0.15% Ni, 152ppm Cu, 145ppm Co from 30m, 14.3ppb Pd (REAC239) including 4m @ 0.22% Ni , 192ppm Cu, 227ppm Co from 38m

(see ASX releases dated 12 September 2013 and 27 November 2013 for details)

In addition to the anomalous geochemical results, trace amounts of the nickel-sulphide mineral violarite (FeNi2S4) were observed in end-of-hole samples from two drill holes at Stud (Figure 1) (REAC273 and REAC238 - see ASX release dated 27 November 2013).

Further, a previous MLTEM survey identified three localised zones of induced polarisation (IP) anomalism, immediately south along strike from the new bedrock conductor (Figure 2) (see ASX release dated 7 July, 2014). The IP anomalism may be related to the presence of disseminated sulphide in the bedrock. Its location along strike from the bedrock conductor may represent a transition from a disseminated to semi-massive sulphide source.

Sheffield’s Managing Director Bruce McQuitty said the Stud prospect was shaping up as a compelling drill target due to the combination of bedrock conductor, strong nickel anomalism near surface and observed trace amounts of nickel sulphide.

“Our Fraser Range tenements continue to demonstrate high prospectivity and potential, and to deliver shareholder value we will continue to assess whether self-funded exploration and /or joint venture or divestment across parts of our Fraser Range package is best.

“Sheffield’s current focus is on delivering an updated PFS on the Thunderbird mineral sands project that will pave the way for commencement of a definitive feasibility study.”

The MLTEM survey identified a number of other IP anomalies worthy of further evaluation, along with a subtle conductor trend in the central-north of the area surveyed. This conductor, although of weak intensity is located in a structurally complex region of folded and faulted interlayered mafic intrusive and sedimentary rocks. These second order targets would initially require follow-up testing with aircore drilling.

Big Bullocks Aircore Drilling Program

Results have also been received from aircore drilling at Sheffield’s Big Bullocks tenement E39/1733, located 85km south of the Tropicana gold mine in the northern Fraser Range (Figure 4). The program comprised 110 broadly-spaced aircore holes drilled to bedrock for a total 3,432m, providing a first pass test of the subsurface geology (Figure 5).

Significantly, mafic/ultramafic intrusive complexes were identified, confirming the presence of rock types suitable for formation of magmatic Ni-sulphide deposits.

In addition, two felsic intrusive units with sulphidic and potassic alteration and anomalous copper values were identified (BBAC027 and BBAC 049). Anomalous drill results are shown in Figure 5 and are discussed below.

BBAC030 returned highest nickel values of 456ppm Ni (40-42m), and 336ppm Ni (42-43m, eoh) in a gabbro adjacent to an interpreted fault.

BBAC027 returned 596.8ppm Cu from 13-14m (eoh) in a sheared, quartz-rich felsic intrusive rock, with potassic alteration and ex-sulphide throughout. The association of anomalous copper with sulphides suggest the area may be a prospective copper-gold target.

BBAC049 returned 496.6ppm Cu from 13-14m (eoh) in a coarse-grained felsic intrusive rock, with abundant interstitial networks of ex-sulphide and moderate potassic alteration. This area is similarly considered a prospective copper-gold target.

BBAC068 returned 541ppb Au and 11ppm As from a single 4m composite (4-8m) within transported silcrete immediately above the interface with weathered bedrock (upper saprolite). Although there were no other anomalous gold values from this or adjacent drill holes, the value is considered significant enough to warrant follow-up work.

Sheffield also sampled and assayed several spoil piles from historic holes drilled by Ponton Minerals in the northwest corner of the Big Bullocks project (Figure 5). An anomalous end-ofhole nickel result reported by Ponton from drill FRNAC144 (from 36-39m) was confirmed by Sheffield’s sampling, returning values of 0.13% Ni (24-30m) and 0.17% Ni (30-34m) in a sheared anorthosite. This area is also considered worthy of follow-up work to investigate the extent of the anomalous nickel value.

Follow-up drilling to investigate the anomalies and targets identified from this very broadlyspaced first-pass drilling program will be prioritised along with other work in the Fraser Range.
