The current drill program is designed as a series of step out drill holes to define the boundaries of high-grade potentially leachable copper mineralization at the Engels Mine prospect. The true widths of the mineralization have not yet been determined.
Dave Jenkins, Sheffield’s President recently commented, "Once again, the drill results expand the area of potentially economic high-grade copper mineralization starting at the surface at the Engels Mine prospect. The Engels’ mineralization remains open for expansion to the north, west, south and to depth. The near surface geometry and high copper grade indicate that this project has the potential to be fast tracked to feasibility at relatively low cost." Photographs, cross sections and a location map of the project can be found on Sheffield’s website www.sheffieldresources.com
Quality Control and Assurance
A rigorous Quality Control and Assurance program (QC/QA) is in place, including systematic inclusion of standard sample materials, blank samples, duplicate samples and inter-laboratory check assaying. 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.
