MAIDEN DRILLING PROGRAM DELIVERS BROAD TALC INTERSECTIONS

KEY POINTS

Sheffield's first diamond drilling program in the Moora Talc Belt intersects significant zones of talc in four of six prospects tested, including:

Fowlers

72.3m of talc from 0.9m depth in drill hole MODD006, and 83.7m of talc from 0.8m depth in drill hole MODD008

Tilleys

26.5m of talc from 45m depth in drill hole MODD009.

Sampling in progress with analytical results expected in August.

Bulk minerals explorer Sheffield Resources ("Sheffield") (ASX:SFX) today announced broad intersections of talc from a successful maiden drilling program at its Moora Talc Belt project located 300km north of Perth in Western Australia"s Mid West region (Figure 1).

The diamond drilling program of 1,238m returned significant talc intersections from four of the six targets tested (see Table 1 for further details). In particular, the talc intersections in drill holes MODD006 and MODD008 at Fowlers are amongst the longest recorded at that prospect (Figure 2).

Sampling of the drill core is in progress and the samples will be submitted for XRF analysis and brightness measurements to determine the suitability of the talc for various end use applications. The results of this work are expected in August.

Whereas many past explorers in the Moora Talc Belt have tended to focus their drilling on shallow talc targets within the zone of weathering (which can be from 30m to 60m depth) Sheffield"s approach is to target fresh talc below the base of weathering and to undertake systematic sampling to identify zones of higher quality talc.

Sheffield has a dominant tenure position over the 175km long Moora Talc Belt (Figure 1). The Moora Talc Belt includes Rio Tinto"s world class Three Springs talc mine which has been producing premium grade microcrystalline talc from a relatively simple "dig-and-deliver" operation since 1948.

Managing Director, Bruce McQuitty said the drilling results are a positive start to Sheffield"s exploration campaign in the Moora Talc Belt.

"Our strategy is to prove up large deposits, or clusters of deposits, containing high quality talc capable of supporting long-life direct shipping mining operations."

Sheffield is one of very few listed public companies in the world offering significant exposure to talc.

About Talc

Talc, with a chemical formula of Mg3Si4O10(OH)2, is a hydrous silicate mineral made up of magnesium (Mg), silica (SiO2) and water. It is one of the softest minerals known to man and is also chemically inert, non-toxic, repels water and readily absorbs oil.

Talc may be sold both as a raw lump product to talc mills and also after milling as a micronised product.

Paper represents the largest end-use industry for talc, followed by the ceramics industry. Talc is also used in the manufacture of plastics. Surging requirements in the automotive market for recyclable and lightweight materials have largely been contributing to the escalating demand for plastics, which in turn is propelling growth of talc products. Talc has many other industry uses including rubber, paints, roofing and pharmaceuticals.

Chinese producers dominate the world market (approximately 50%) with regard to volume production. The Chinese talc industry has been facing a number of challenges which have created insufficient supply of high-grade talc. This is due primarily to the exhaustion of high grade talc mines in China and an increase in demand both domestically and in export markets. Chinese output of high grade talc is considered insufficient to meet the current needs of neither the Chinese domestic market nor export demand.

During 2008 and 2009 talc prices ranged between US$259 and US$460 per tonne depending on grade.

North Perth Basin Mineral Sands Project Update

Assaying and resource estimation work is progressing according to the timetable announced on 2 June 2011. Resource estimation is in progress for the Company"s Yandanooka prospect.

Pilbara Iron Project Update

Detailed geological mapping and sampling has been completed at the Company"s Three Pools project, located 20km north of Newman. An aboriginal heritage survey has been scheduled for late July, ahead of drilling planned to commence in September.

ABOUT SHEFFIELD RESOURCES

Sheffield Resources Limited (Sheffield) is a new exploration company with a bulk minerals focus. The Company"s Projects are geared towards the steel industry feed cycle (iron ore and tungsten) and the emerging fillers-ceramics-pigments cycle (talc, zircon, titanium dioxide).

ASX Code – Market Cap @ 25cps -
SFX $14.7m
Issued shares –58.6mNEW EXPLORATION COMPANY -BULK COMMODITY FOCUS Cash -$5.8m(at 31 Mar 2011)

The Company has over 6,000km2 of highly prospective tenure, all situated within the state of Western Australia.

TALC

Sheffield has 1,152km2 of tenure over the 175km-long Moora Talc Belt which represents a dominant ground position over a region that has, for the last 50 years, been exclusively controlled by major mining companies.

The Moora Talc Belt includes the large Three Springs mine which is owned by Rio Tinto Limited subsidiary Luzenac Australia Pty Ltd. Three Springs is renowned for producing high purity talc and is a relatively simple "dig-and-deliver" operation.

The existing infrastructure is excellent. A railway and a sealed highway transect the project and connect to Geraldton port approximately 170km to the northwest.

Sheffield"s large tenement holding contains numerous talc occurrences and has the potential to become a strategic talc asset. Sheffield therefore represents a unique opportunity for investors to gain exposure to one of the few high-grade talc explorers in the world.

HEAVY MINERAL SANDS

Sheffield controls over 5,000km2 of mineral sands tenure in the established North Perth Basin mineral sands province and the emerging Carnarvon, Eucla and Canning Basin provinces.

Sheffield"s North Perth Basin tenement package of over 2,500km2 contains seven advanced exploration projects: West Mine North, Ellengail, Yandanooka, Durack, Beekeepers, and Irwin which are located near Eneabba and the large McCalls deposit - a former BHP project located near Gingin. These projects are well located close to existing mineral sands operations and to a network of highways and railway lines connecting to Geraldton and Fremantle/Kwinana ports. Sheffield"s strategy is, subject to exploration success, to build multiple HMS projects capable of supporting a flexible mobile mining plant.

IRON

Sheffield"s Pilbara iron ore projects consist of five granted tenements and 15 tenement applications, of which three are second-in-time applications and nine are subject to ballot with multiple competing parties. Sheffield"s strategy is to target hematite mineralisation adjacent to infrastructure in the world class Pilbara iron province and to build up consolidated tenement holdings over time. Reconnaissance mapping has so far identified iron enrichment on three of the Company"s tenements.
