MONTREAL, QUEBEC--(Marketwire - July 21, 2010) - Creso Exploration Inc. ("Creso" or the "Company") (TSX VENTURE:CXT) is pleased to announce the occurrence of visible gold at four locations in Hole MC-09-01 (Hole #1) within a 90 meter interval of hydrothermal breccia, as well as partial results of MC-09-02 (Hole #2) on the Minto Project. Both holes have been deepened by over 300 meters from their previous depths and all cores from both holes will be submitted for analysis.

Hole #1 was re-entered and drilled from the previous end-of-hole depth of 269 meters. At a depth of 506 meters the drill intersected a hydrothermal breccia containing finely disseminated pyrite of 2% to 4% by volume. Geologists have identified visible gold at depths of 546 meters, 548 meters, 568 meters, and 586 meters. The hole is currently at a depth of 602m and analyses are pending on all cores from the re-entered hole. The collar of Hole # 1 is located 35 meters northeast of the collar of Hole # 2.

Hole #2 (June 9, 2010 Press Release - 65.7 meters of 18.2 g/t Au and 79.6 meters of 4.61 g/t Au in Hole #2 on the Minto Project) was deepened by 382m. The preliminary assay results are as follows: 5.82 g/t Au over 7.6 meters beginning at 423 meters depth (including 8.24 g/t Au over 5.0 meters). In excess of 300 meters of core remain to be analysed from Hole #2. The bottom zone is new and no true width has been determined yet. Analyses are pending on all cores from the re-entered Hole #1.

This gold mineralization is contained within a broader zone of potassic alteration within a hydrothermal breccia that displays rims of what are interpreted to be very fine secondary K-feldspar on many breccia fragments within a matrix of quartz and calcite. Within the mineralized interval, fine disseminated pyrite makes up approximately 3% by volume of the core.

Reflex measurements on the hole indicate that the hole deviates from original coordinates crossing the core locations of Hole 2, indicating zones of vg to be 20m west of the pit edge and 400+m deep, an area previously untested.
