Sheffield identifies large conductor at Red Bull

THE DRILL SERGEANT: Sheffield Resources (ASX:SFX) has received results from high-powered Moving and Fixed Loop Transient Electromagnetic (MLTEM& FLTEM) ground geophysical surveys at the company’s Red Bull nickel-copper project, located within 20 kilometres of Sirius Resources’ (ASX: SIR) Nova nickel-copper deposit, in the Fraser Range Nickel Province of Western Australia.

The MLTEM survey was completed at the Earlobe and Stud prospects, where previous aircore drilling had identified nickel-copper-cobalt anomalism.

Sheffield said the survey had identified a broad, deep conductive anomaly immediately to the west of the Earlobe prospect (anomaly RBD1), and several local zones of strong polarisation coincident with drillhole geochemical anomalies at the Stud prospect.

A single FLTEM survey was then completed over RBD1 to better define the conductor and provide for more robust drill target design.

Sheffield’s geophysical consultants have modelled the RBD1 conductive source as large (350 x 1,200m), striking WNW-ESE with moderate NNE plunge and a depth to top of about 550-600m.

RBD1 is located at the junction of three interpreted faults and Sheffield’s main target mafic/ultramafic domain.

Sheffield considers the RBD1 conductor to be an exciting new target, with similar hallmarks to Sirius Resources’ nearby Nova discovery.

“Although the target is deep, we are encouraged by the high conductance levels, large scale and favourable geological setting,” Sheffeild Resources managing director Bruce McQuitty said in the company’s announcement to the Australian Securities Exchange.

“This is a similar sized conductor, with similar conductance, to Sirius Resources’ main Nova conductor.

“The IP anomalies at Stud are also encouraging, being located in an area of significant nickel-copper-cobalt anomalism where disseminated nickel and copper sulphides have been observed in end-of-hole aircore drill chips.

“Sheffield’s value is underpinned by the world class Thunderbird mineral sands project, however we are well funded to continue the search for high value nickel targets in the Fraser Range and drilling of this target will be prioritised in our 2014 exploration program.”
