Sheffield Commences 30,000 Foot Drill Program

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 30, 2006) - Sheffield Resources Ltd.("Sheffield")(TSX VENTURE:SLD) announces that its wholly owned subsidiary American Sheffield, Inc. has commenced drilling at its Moonlight Copper Project in Plumas County, California. American Sheffield has a contract for up to 30,000 feet of HQ gauge core drilling. The contract is with Ruen Drilling Incorporated, a California licensed company, based in Clark Fork, Idaho. Permission was granted by the USDA Forest Service for the expanded drill program.

Dominick and Dominick Securities Inc. of Toronto have agreed to act as Sheffield's agent in assisting Sheffield in securing a private placement. The funds from the private placement will be used for costs related to confirmation and expansion of the 240 million tons of copper mineralization previously reported by Placer Dome at the Moonlight Copper Project.

The initial 2005 drill program was successful in cutting 185 metres (607 feet) grading 0.54% copper and 7 gpt silver followed by a deeper 68 metre (223 feet) long intersection containing 0.44% copper and 5 gpt of silver. The first drill hole encountered potentially economic grade copper mineralization at 9 metres of depth in bold contrast to depths of 75 metres and 45 metres in the two nearest holes drilled by Placer Dome Inc., the previous operator. The 2005 drill program was halted to avoid potential damage to softened forestry roads occasioned by unseasonable heavy rain falls.

The exploration program is managed by Robert Wetzel, a California registered professional geologist and qualified person. The technical information in this news release has been prepared in accordance with Canadian regulatory requirements set out in National Instrument 43-101. David M Jenkins, P.Geo., and President of Sheffield Resources is designated the qualified person for the Moonlight Project.
