SHEFFIELD ANNOUNCES CONTRACT FOR 30,000 FOOT DRILL PROGRAM
Sheffield Resources Ltd.'s wholly owned subsidiary, American Sheffield Inc., entered into a contract for up to 30,000 feet of HQ gauge core drilling at its Moonlight copper project in Plumas county, California. The contract is with Ruen Drilling Inc., a California-licensed company based in Clark Fork, Idaho. Ruen Drilling was selected by American Sheffield on the basis of equipment and footage rates. Permission has been granted by the USDA Forest Service for the expanded drill program, which is scheduled to begin in mid-May after spring breakup.
The initial 2005 drill program was successful in cutting 185 metres (607 feet) grading 0.54 per cent copper and seven grams per tonne silver, followed by a deeper 68-metre-long (223-foot-long) intersection containing 0.44 per cent copper and five grams per tonne of silver. The first drill hole encountered potentially economic-grade copper mineralization at nine 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 rainfall.
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, PGeo, president of Sheffield Resources, is designated the qualified person for the Moonlight copper project
