Pacific Comox Resources Ltd.: 43 Hole Diamond Drill Program Completed on Mabel Property in Mexico to Support N. I. 43-101 Compliant Resource Estimate Which is Underway

TORONTO, ONTARIO--(Marketwire - July 27, 2009) - Pacific Comox Resources Ltd. (TSX VENTURE:PCM) reports 43 diamond drill holes (1,003 meters) have been completed on the Mabel property in northern Sonora State, Mexico. Almost all the holes drilled on Mabel previous to this program were reverse circulation. In the current program 27 diamond drill holes twinned reverse circulation holes in the Carmelitas Zone and will provide additional required structural data for the completion of a N. I. 43-101 compliant resource estimate. The assays will be reported when received.

Carmelitas has been an area of concentrated drilling to outline at/near surface gold/silver mineralization on a tighter drill spacing basis than the other 4 zones.

To July 2009, excluding the current diamond drill program, 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.

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.

Exploration Program On Mabel Property Northern Sonora Mexico

Pacific Comox has drilled 43 diamond drill holes totalling 1,003 meters in the current program and previously had drilled 611 holes on the Mabel property totalling 12,546 meters.

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. For example, 11 contiguous but widely spaced 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 with an average spacing of about 50 meters. More closely spaced drilling is needed to assess the economic potential of the zones. In the current campaign 15 holes were drilled on Gate. One hole tested an EM geophysics anomaly adjacent to Carmelitas.

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. 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.

Bhagwat Singh P. Eng. serves as the qualified person (QP) for the sampling and exploration programs under the definitions of National Instrument 43-101. The geologist on the Mabel program is Cesar Lemas. For the RC drill program the product was bagged separately for each meter of drill advance. In the current diamond drill program the core were sawn and intervals selected for assay. A split RC or diamond drill sample was shipped by Company personnel to the ALS Chemex sample preparation facility at Hermosillo, Sonora which forwards prepared samples to the ALS Chemex Vancouver facility for assay.
