NEWS RELEASE

SHEFFIELD INTERSECTS 26 METRES OF 1.13% COPPER

Vancouver, BC – March 18, 2008

- Sheffield Resources Ltd. (“Sheffield”) (TSX-V: SLD) and (FRANKFURT:

“S2Q”) is pleased to report additional assay results from the diamond drilling sampling program at the Engels

Mine Prospect which is located on Sheffield’s Moonlight Copper Project in Plumas County, California.

The current drill program is designed to define high-grade copper mineralization, which may in part be mined in

the initial starter pit of a copper leach mine at the Moonlight Project. In the current program a total of 32 core

holes have been drilled at the Engels Mine Prospect and a further 15 reverse circulation holes have been drilled in

the Moonlight Deposit. Assays for two core holes reported herein complete the assaying for the core holes drilled

in the recent drilling program. Samples from the 15 reverse circulation holes are expected to be announced

shortly. Sheffield plans to use the sample material derived from the core and reverse circulation drill cuttings in

metallurgical programs to begin characterization of the several types of mineralization recovered in this season’s

drilling programs. Silver and gold contained in the mineralization are highly unlikely to be recovered in a copper

leach operation, but may contribute to revenue if some of the high-grade copper is recovered into a flotation

concentrate.

The Engels’ mineralization remains open for expansion to the north, west, south and to depth. We are particularly

excited about these results from the Engels Mine Prospect during this period of rising copper prices. The near

surface geometry, high grade and oxidation all indicate that this project has the potential to be fast tracked to

feasibility at low cost." Photographs of the project can be found on Sheffield’s website

www.sheffieldresources.com

The drill holes reported herein are from the first modern drill program in the Engels Mine area, which is one of

four principal target areas on the Moonlight Copper/Silver Project. A preliminary NI 43-101 compliant resource

was reported in March 2007 for the adjacent Moonlight Deposit which also remains open to resource expansion

laterally and to depth.

Drilling will resume in the spring when Sheffield will continue to define both the Engels Mine high-grade

mineralization and the historical Moonlight Deposit oxide copper resource. The Company expects to report an NI

43-101 compliant resource for each deposit in 2008.

Quality Control and Assurance

A rigorous Quality Control and Assurance program (QC/QA) is in place, including systematic inclusion of

standard sample materials and duplicate analyses. Samples are sent in sealed containers to ALS Chemex in Reno,

Nevada. ALS Chemex is a recognized ISO 9000 registered laboratory. The control samples and duplicate assay

results received for the drilling program demonstrated to Sheffield Resources that the assay results reported herein

are reliable.

The exploration program is managed by Robert Wetzel, a California registered professional geologist and

qualified person. David M Jenkins, P.Geo., and president of Sheffield Resources is designated the qualified

person for the Moonlight Copper Project.
