*previously reported: all holes are uncut and over core length; core length is estimated 50-90% of true width; 1 g/t Au multiplied by 0.0291666 equals troy ounces per short ton (to convert from metres to feet multiply by 3.2808). VG: visible gold

QA/QC was followed in sampling the core. The core is sawed in half for sampling. Standards, blanks and duplicates were inserted into the stream of core samples every 20 metres. The core was assayed at Expert Laboratory Inc. at Rouyn-Noranda, PQ using 30 gram samples. The core samples were analyzed using the fire assay method and AA finish. Assays of 1 g/t Au and greater are re-assayed using the gravimetric method. Fred Sharpley, P.Geo is the QP for the Omega Property.

Robert Kasner commenting on these results stated: The open pit area for the first 100 metres is expanding beyond our initial expectations. These new results will greatly expand the tonnage outlined so far. There are several fill-in drill holes yet to be completed in this 100 metre deep pit and assays to come from several already completed. A lot of the assays previously reported left out assays that can now safely be incorporated. For example hole OM-11-28 has been recalculated over a much greater distance and returned 1.034 g/t over 48 metres. A numberof holes are now being recalculated and will be released at a later date. It is now possible to begin working on a deeper pit than 100metres
