TORONTO, ONTARIO--(Marketwire - Jan. 23, 2009) - Pacific Comox Resources Ltd. (TSX VENTURE:PCM) reports the assay results for the final 40 holes in its RC drilling program to outline additional at/near surface gold/silver mineralization on a tighter drill spacing basis on the Carmelitas Zone of the Mabel property in northern Sonora State, Mexico. The 40 holes averaged 1.0 g/tonne gold and 30 g/tonne silver over an average interval of 3.5 meters. The assays for each hole are given in Table 2. To January 2009, 195 mineralized holes have been drilled in the Carmelitas Zone (see Table 1 below) which includes 46 higher grade holes that averaged: Gold grade 2.9 g/tonne, Silver grade 104 g/tonne, with an average mineralized interval of 4.5 meters. - A resource estimate for the Mabel property is underway and will include all the holes drilled to-date. - It is planned to follow the current resource estimate with a preliminary economic assessment of the project based on the completed metallurgical test work and the resource estimate. ---------------------------------------------------------------------------- Table 1: Summary of Mabel Results by Area To January 2009 (Including Previously Reported) ---------------------------------------------------------------------------- Number Thickness Gold Silver ---------------------------------------------------------------------------- Area Of Holes (meters) (g/tonne) (g/tonne) ---------------------------------------------------------------------------- Carmelitas Zone Mineralized Holes 195 3.9 1.2 42 ---------------------------------------------------------------------------- Carmelitas Zone Holes Include 46 4.5 2.9 104 ---------------------------------------------------------------------------- Gate North 11 5.0 1.6 78 ---------------------------------------------------------------------------- Gate South 8 3.0 0.5 35 ---------------------------------------------------------------------------- Ridge Zone 10 3.0 1.7 35 ---------------------------------------------------------------------------- Ridge Zone - 3 Meter Chip Samples 14 - 0.7 68 ---------------------------------------------------------------------------- Micho - RC Holes 10 All Holes Reported Au/Ag Mineralization ---------------------------------------------------------------------------- Micho - 3 Meter Chip Samples (1) 9 - 4.6 192 ---------------------------------------------------------------------------- 1. Also reported 0.43% average copper grade in chip samples. ---------------------------------------------------------------------------- Note: All thicknesses and grades are arithmetic averages. ---------------------------------------------------------------------------- Pacific Comox has drilled 611 holes on the Mabel property totalling 12,546 meters giving an average hole length of 20 meters. Carmelitas has been an area of concentrated closed spaced drilling to provide data for the resource estimate but it still has exploration potential in several areas where the drilling has been more widely spaced. As shown in Table 1, all the zones which have been drilled have returned holes or widely spaced clusters of holes which offer significant exploration potential. More closely spaced drilling is needed to assess the economic potential of the holes. For example, 11 contiguous holes in the Gate North area have averaged 1.6 g/tonne gold and 78 g/tonne silver over average mineralized intervals of 5 meters. However, the holes are approximately 50 meters apart and more closely spaced drilling is planned to test the ultimate size of the zone and increase the hole density. Preliminary metallurgical work, previously reported, on a 100 kg composite sample from the areas of drill intersected mineralization has been partially completed. The heap leach amenability tests (coarse mineralization bottle roll cyanidation tests) were conducted on approximately 1,000 gram of whole mineralization at different crush sizes for a 14 day period. Test results are summarized in Table M-1 below. The heap leach amenability cyanidation recovery of gold increased from 85.1% to 86.7% for gold and from 81.7% to 86.0% for silver when the feed size was decreased from 12.7 mm (1/2 inch) to 2.0 mm.
