TWELVE NEW NICKEL AND GOLD TARGETS OUTLINED IN FRASER RANGE
KEY POINTS
-
Grant of three new exploration licences expands Sheffield’s footprint in Fraser Range
-
Five substantial new nickel targets identified from review of historic (pre the discovery of Nova/Bollinger) data and initial reconnaissance sampling, including:
-
Substantial auger soil nickel anomalies with peak values ranging from 1671,274ppm Ni
-
Only one anomaly has been drilled, intersecting ultramafic rocks with nickelcopper mineralisation
-
Rock chip assay results up to 1.15% nickel from weathered ultramafic
-
Seven new gold targets delineated by high quality historic exploration activity involving extensive shallow drilling
-
Several targets ready for next stage of focussed deeper drilling
Sheffield Resources (“Sheffield”) (ASX:SFX) today announced the identification of 12 substantial new nickel and gold targets on recently granted tenements at its Fraser Range project.
The granted tenements are located within the northern foreland region of the Tropicana Belt adjacent to the Fraser Complex (Figure 1). The tenements are situated approximately 240km south of the Tropicana gold mine and 30km northwest of Sirius Resources NL’s (ASX:SIR) Nova/Bollinger Nickel-Copper deposit.
A review of past exploration has identified five substantial new nickel targets associated with late stage ultramafic intrusions. The ultramafic rocks are thought to have intruded deepseated structures separating the Yilgarn Craton from the Fraser Complex. Only one nickel anomaly has been tested by drilling, as gold was the principal focus of previous explorers.
The tenements also contain seven gold targets delineated by early stage historic shallow drilling programmes by explorers targeting the region for Tropicana style gold mineralisation.
Managing Director, Bruce McQuitty said Sheffield has assembled a large and strategic tenement holding within the highly prospective Fraser Range Nickel Province and adjacent Tropicana Gold Belt.
“A substantial amount of historical early stage exploration has been completed over these tenements, providing well defined nickel and gold targets for follow up work. These targets have come at no cost to Sheffield.”
“Historically the region has been the focus of gold exploration with the majority of work completed prior to the discovery of Nova/Bollinger. It is clear from the review of past exploration that a number of promising new nickel targets remain untested.
“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.

Figure 1: Location of recently granted tenements in the Fraser Range region
The recently granted exploration licences, E28/2481, E28/2453 and E63/1696, are located within Sheffield’s Fraser Range project (Figure 1). The project now comprises fifteen granted exploration licences and two applications over a total area of 2,131km[2] . A review of historic exploration has identified five new significant nickel targets and seven advanced gold targets on the recently granted tenements, as outlined below.
Nickel Targets
The nickel targets occur on E28/2481 “Oak Dam” which is located around 50km to the north of Sirius’s Nova/Bollinger Nickel-Copper deposit. The targets are associated with mafic/ultramafic intrusions within the northern foreland zone (Tropicana Belt) of the Albany-Fraser Orogenic Belt. This is a zone of intense deformation which has been exploited by late stage differentiated ultramafic, mafic and carbonitite intrusive complexes.
The five targets, named Dreadnought, Depth Charge, Lifeboat, Torpedo and Frigate, are defined by historical auger soil sampling undertaken by AngloGold Ashanti Ltd (“AngloGold”) (as manager of the Tropicana JV with Independence Group NL). The nickel soil anomalies are associated with magnetic highs (Figure 2) and sporadic outcrop of ultramafic rocks. Limited reconnaissance rock chip sampling undertaken by Sheffield has confirmed elevated nickel values associated with these targets.

Dreadnought
The Dreadnought soil nickel anomaly located within E28/2481 is associated with a northeast trending magnetic high with a strike length of over two kilometres. The magnetic feature correlates with a small outcrop of highly weathered, ferruginous and silicified ultramafic rock.
The very strong nickel soil anomaly (>140ppm Ni) has a strike length of more than 1.5km and a width of 350m, with a maximum value of 1,274ppm Ni . The core of the anomaly comprises 6 samples assaying over 400ppm Ni. Sheffield’s rock chip sampling of a weathered ultramafic returned a maximum value of 1.15% Ni (Table 2, Appendix 1).
Historic trenching across the ultramafic unit, thought to date from the early 1970s is the only evidence of prior exploration for nickel at Dreadnought (Figure 3).
Depth Charge
The Depth Charge anomaly overlies the southern portion of a 14km long trend comprising a series of discontinuous ultramafic intrusions with varying degrees of magnetic anomalism. A strong soil anomaly (>140ppm Ni) approximately 1.6km long and up to 300m wide occurs at the southern end of this trend. Auger soil samples retuned a maximum value of 696ppm Ni .

Figure 3: Historic trenching of ferruginous talc-carbonate altered ultramafic from Dreadnought
Widely spaced aircore drilling (400m x 100m) by AngloGold intersected mafic to ultramafic granulites within quartzofeldspathic gneisses. AngloGold noted trace amounts of sulphide in the ultramafic rocks and considered the geological setting to be highly prospective for nickel mineralisation. Consequently, selected drill holes were re-assayed for nickel. Significant intersections include:
-
34m at 0.18% Ni , 242ppm Cu, 93ppm Co, 26ppb Pd and 21ppb Pt from surface to end of hole (DCA100), including 4m @ 0.32% Ni , 520ppm Cu, 105ppm Co, 70ppb Pd and 60ppb Pt from 20m
-
48m @ 0.17% Ni , 33ppm Cu, 96ppm Co, 6ppb Pt from surface to end of hole (DCA102) including 4m @ 0.36% Ni , 48ppm Cu, 205ppm Co and 5ppb Pt from 12m
-
(>0.1% Ni cut-off, refer to Appendix 1, Table 1 for full details).
An end-of-hole multi-element sample from drill hole DCA100 returned highly elevated copper and nickel results comprising 1m @ 0.25% Ni and 0.11% Cu from 33m (EOH sample).
Life Boat
The Life Boat prospect is located along the same ultramafic trend as Depth Charge and is defined by a single anomalous auger soil sample of 167ppm Ni associated with an aeromagnetic high. The auger sampling grid at Life Boat is 400m x 100m.
Torpedo
The Torpedo prospect is located at the north-eastern end of the 14km long trend that contains both Life Boat and Depth Charge. The nickel soil anomaly (>140ppm Ni) at Torpedo, as defined from 400m x 100m auger sampling, has a strike length of 1.6km and a width of 300m with a maximum value of 443ppm Ni .
Frigate
The Frigate prospect differs from the other nickel targets as it is associated with a magnetic low. Historic auger soil sampling (at 400m x 100m spacing) attained values of up to 332ppm Ni at the 1.25km by 500m wide (>140ppm Ni) anomaly. Sheffield obtained 889ppm Ni from a rock chip sample of iron stained tremolite-actinolite schist outcropping near this locality (Table 2).
Gold Targets
Within recently granted exploration licences E28/2481, E28/2453 and E63/1696 historic exploration by companies such as AngloGold and Sipa Resources Ltd (“Sipa”, ASX:SRI) has identified seven substantial gold exploration targets.
The exploration completed to date comprises early stage auger soil sampling and widespread shallow aircore dilling with minor follow-up RC and diamond drilling. This thorough, high quality early stage exploration has positioned the project for the next stage of focussed deeper drilling and evaluation.

Dragon Fly (E28/2481)
The Dragon Fly gold prospect features gold mineralisation associated with tabular zones of biotite-carbonate-sericite-pyrite alteration in a host lithology of intermediate to felsic garnet bearing gneiss, quartz-feldspar garnet gneiss and minor amphibolite.
AngloGold undertook extensive pedogenic calcrete auger drilling over Dragon Fly on a 100m by 400m grid which outlined a 1.6km by 0.6km gold anomaly (Au > 10ppb ), within a larger but discontinuous gold anomalous region of 6km by 4km. Aircore drilling produced a best intersection of:
9m @ 1.30g/t Au from 24m (DFA021), including 4m @ 2.67g/t Au from 28m. (>0.1g/t Au cut-off, refer to Appendix 1, Table 6 for full details).
A total of 25 reverse circulation holes were drilled for 3,834m on a 200m x 50m spacing, with one diamond hole drilled to 183.6m depth down-hole. Significant intersections include:
-
8m @ 0.96g/t Au from 27m and 4m @ 0.97g/t Au from 46m (DFRC004);
-
8m @ 1.00g/t Au from 39m (DFRC009), including 1m @ 3.08g/t Au from 42m;
-
2m @ 1.11g/t Au from 74m; 1m @ 5.36g/t Au from 78m and 6m @ 1.12g/t Au from 85m (DFRC011);
-
2m @ 2.29g/t Au from 50m , including 1m @ 4.04g/t Au from 51m (DFRC020)
-
(>0.5g/t Au cut-off, refer to Appendix 1, Table 4 for full details).
Drilling has confirmed the presence of a large alteration system and that the mineralisation remains open at depth.
Scorpion (E28/2481)
The Scorpion prospect comprises two pedogenic calcrete auger gold (>10ppb Au) anomalies. The northern anomaly has dimensions of 1.8km by 0.4km with a maximum value of 178ppb Au while the southern anomaly is 1km by 0.3km with a maximum value of 85ppb Au. AngloGold drilled a total of 119 aircore holes for 2,818m at 400m x 100m spacing. A single line of three RC holes spaced at 100m were drilled at the southern zone returning a best intersection of:
2m @ 2.6g/t Au from 115m (SNRC005)
- (>0.5g/t Au cut-off, refer to Appendix 1, Table 4 for full details).
The northern anomaly was not tested by RC drilling. Gold mineralisation was found to be associated with mafic units within a dominantly granitic domain.
Tomahawk (E28/2481)
The Tomahawk prospect has a 2km by 0.2km pedogenic calcrete auger anomaly with a maximum value of 43ppb Au (400m x 100m auger spacing). A second pedogenic anomaly (1km by 0.4km) occurs just to the northeast of Tomahawk. Although AngloGold’s initial shallow aircore drilling of these targets (at 400m x 100m spacing) returned only weakly anomalous results, they are located in a structural setting considered prospective for Tropicana-style gold mineralisation.
Theofrastos (E28/2453)
The Theofrastos gold prospect, situated within E28/2453, was previously explored by Sipa Resources Ltd. Auger drilling outlined a pedogenic calcrete gold anomaly of 6km by 2km with a maximum value of 85ppb Au (Figure 5). The soil anomaly has been tested by extensive RAB and aircore drilling which was followed by 27 RC drill holes.
The best intersection obtained by Sipa was;
-
10m @ 1.29g/t Au from 64m, including 1m @ 7.8g/t Au from 71m (TFC010)
-
(>0.1g/t Au, refer to Sipa’s ASX announcement dated 26 May, 2011 for full details)
The mineralised lodes occur in altered felsic gneiss and schist within an albite-tremolite-biotite alteration zone containing disseminated pyrite and trace amounts of chalcopyrite and molybdenite. The lodes strike north-northeasterly and dip shallowly to the southeast.

Heraclitus (E28/2453)
Heraclitus is located 4km to the southeast of Theofrastos. It has an 8km by 2km pedogenic calcrete gold anomaly (>10ppb Au) with a maximum value of 68ppb Au (Figure 5). The anomaly has been tested with extensive RAB and aircore drilling with minor RC follow-up (12 holes). Significant intersections include;
-
1m @ 9.1g/t Au from 93m (HRC001);
-
1m @ 1.01g/t Au from 75m (HEC008); and
-
1m @ 2.08g/t Au from 67m (HEC009)
(>0.1g/t Au, refer to Sipa’s Quarterly Report 31 January 2011and ASX announcement 18 February 2010 for details).
Mineralisation occurs over a strike length of 2.5km with the main zone of mineralisation still open to the south-west. The mineralisation is between 10m and 20m thick and dips moderately to the south. It is hosted by a discrete zone of biotite gneiss containing minor garnet and tourmaline.

(Sipa ASX release dated 18 February 2010)
Leuccipus (E28/2453)
The Leuccipus prospect was initially delineated by a 2km by 0.6km pedogenic calcrete auger anomaly with a maximum value of 62ppb Au. Sipa completed a detailed first pass RAB (433 holes for 12,875m) and aircore (22 holes for 88m) drilling programme across the soil anomaly. This delineated a more discrete 0.5km by 1km end-of-hole gold anomaly.
A summary of significant RAB results were reported by Sipa in their ASX announcement of 15 August, 2011. Best results include;
-
7m @ 0.37g/t Au from 20m to end of hole, including 1m @ 1.0 g/t Au from 26m (WDR1816);
-
10m @ 0.65g/t Au from 20m to end of hole, including 1m @ 3.5 g/t Au from 29m (WDR1817)
-
(>0.1g/t Au)
Mineralisation is hosted by a sericite-chlorite-tourmaline felsic volcanic schist. The target is yet to be tested by RC drilling.

Leila (E63/1696)
At the Leila prospect, regional pedogenic calcrete auger sampling was undertaken by Sipa on a 0.2km by 1km grid, closing into a 0.1km to 0.2km grid over the main target. A maximum value of 86ppb Au was obtained. RAB drilling to a maximum depth of 54m, on a 50m by 200m grid, returned the following significant intersections:
-
2m @ 1.46g/t Au from 20m and 5m at 0.24 g/t Au from 24m (WDR3013);
-
4m at 0.61g/t Au from 29m (WDR3033)
-
(>0.1g/t Au cut-off, refer to Appendix 1, Table 6 for full details).
The target is yet to be tested by RC drilling.
Summary
Extensive first pass exploration programs completed in recent times by gold explorers AngloGold and Sipa have identified twelve nickel and gold exploration targets within the recently granted tenements that warrant follow up work. In several cases the targets are ready for the next stage of focussed deeper drilling.
Sheffield’s Fraser Range tenements continue to demonstrate high prospectivity and potential, and to deliver shareholder value. The Company will continue to assess whether self-funded exploration and /or joint venture or divestment across parts of our Fraser Range package is best.
