ICS Copper Drills 40.9 meters of 1.10% Cu and 16.0 meters of 1.56% Cu at the Mokambo Property
ABBOTSFORD, BC, July 23 /EMWNews/ - ICS Copper Systems Ltd. (ICX:TSX.V) is pleased to announce that the Company has obtained important assays and widths from the sulphide twinning confirmation diamond drill program which is now completed. The latest results show that HOLE M-08-S-04 INTERSECTED 40.9 METERS TRUE THICKNESS OF 1.10% TOTAL COPPER AND HOLE M-08-S-05 INTERSECTED 16.0 METERS TRUE THICKNESS OF 1.56% TOTAL COPPER. To confirm that the historic mineral estimate was accurate and to bring the estimate into a NI 43-101 compliant mineral resource, ICS re-sampled the same historic sulphide drill holes that were twinned. The re-sampled new assay results show a very good correlation to the historic assay results as illustrated below. The first table illustrates a few selected mineralized zones in each drill hole, for direct comparison of the historic assays and the re-sampled assays (A H Knight Labs, Kitwe, Zambia, 2008).

Sulphide Twin Drill Program The twinned hole drill sites were chosen not only to confirm the largest defined areas of mineralization but to confirm the other mineralization along strike (+ 3,400 meters) over the property. The 5 hole sulphide twinning program results are now complete and again the assay results compare well with the historical drill results. Direct assay comparison with respect to lithology or depth within the hole is difficult, due to hole deflections in the historic and twinned holes that subsequently vary the depth and the lithologie thicknesses. Indirect comparison shows however, highly anomalous mineralized zones that are equivalent within those lithologies. In several holes, the mineralized intersections were thicker than the historic sulphide holes due to previous operators not sampling all mineralization in the core.

RSG Global, a subsidiary of Coffey Mining is presently auditing these results as part of their requirements under NI 43-101 as they prepare to undertake a new mineral resource calculation and subsequent Technical Report. Oxide Copper Drill Program ICS is also pleased to announce that the shallow (100 meter) grid drill program covering the property is now complete. Assay results are pending but will be fast tracked so that they can be included in RSG Global's mineral resource estimation and subsequent Technical Report. It is anticipated that the report will be finalized by mid to late August so that GRD Minproc can economically evaluate the Mokambo Property. David Makepeace, P.Eng. M.Eng, a director of the Company and its acting Chief Operating Officer, a qualified person as defined by National Instrument 43-101, supervised the preparation of the technical information in this news release. President and CEO of ICS, Graham Chisholm comments: "The sulphide drill program corroborates the historical assays and the results above speak for themselves. We are pleased with these drilling results and we look forward to receiving the NI 43-101 Technical Report being prepared by Coffey Mining." ICS COPPER SYSTEMS LTD.
