Manson Creek Resources Ltd.: CR Drilling Intersects 0.51% Copper, 0.016% Molybdenum, and 2.49 g/t Silver Over 63.58 Meters

CALGARY, ALBERTA--(CCNMatthews - Aug. 11, 2005) - Manson Creek Resources Ltd. (TSX VENTURE:MCK) is pleased to announce the assay results for drill holes 05CR01 through 05CR08. The eight drill holes were recently completed on the CR prospect located near Houston, British Columbia.

The first phase of drilling has confirmed that numerous zones and styles of mineralization are present in the mineralized porphyry. The new zone of porphyry discovered at the Burn Anomaly is also mineralized.

The work completed to date, mapping, trenching, and diamond drilling, has outlined a mineralized porphyry system that is 900 meters by 100 to 180 meters. The east-west trending porphyry remains open along strike and depth.

The CR drill program consisted of eight drill holes that totaled 1,580 meters of NQ core. All of the drill holes except for 05CR03 were drilled at a 180 degree azimuth. Hole 05CR03 was drilled due north and all holes were drilled at a -45 degree angle. Please refer to the drill hole location plan map attached for the location of all drill holes.

The drill program was designed to test both the Burn geochemical soil and geophysical anomalies and to test the porphyry units identified in historic exploration programs. All of the drill holes intersected variably mineralized porphyry units. Three drill holes, 05CR06 - 05CR08, tested the Burn anomaly and all three intersected mineralized crowded feldspar-quartz-biotite pheric porphyry (QFP). Drill holes 05CR07 and 05CR08 ended in mineralized QFP and only partially tested the newly discovered porphyry unit. The new QFP zone was cut in drilling along 200m of strike length.

Geology

Two mineralized intrusive units are present on the CR property. The oldest unit is a fine-grained felsic porphyry and it is locally disrupted by a younger crowded feldspar-quartz-biotite pheric porphyry (QFP). Both of the units are observed to host copper and molybdenum mineralization.

Chalcopyrite and molybdenite are the main minerals of economic importance and they occur alone or in combination in one of the four main styles of mineralization recognized at CR. These are: 1) chalcopyrite in silicified andesite (country rock): 2) disseminated and veinlet mineralization in the QFP: 3) micro veinlet and veinlet mineralization in the fine grained felsic porphyry: and 4) localized molybdenite-rich stockworks. The distribution and extent of the molybdenite-rich stockworks remains poorly understood. Narrow intercepts, including 3.9m of 0.86% Mo, 4.9m of 0.075% Mo, and 14.1m of 0.052% Mo are encouraging and demonstrate the potential for high grade molybdenum mineralization in the system.

Hydrothermal alteration is very strong, well developed, and displays many of the characteristics that occur in mineralized copper - molybdenum porphyry systems. The dominate alteration types observed in the core are zoned from east to west. The intensity of secondary potassium feldspar with localized secondary biotite (potassic alteration) associated with strong silicification and patchy strong sericite alteration increases in the drill holes to the west. This alteration pattern indicates the best exploration potential could occur in the largely untested western part of the system.

Further work will be undertaken to trench areas west of the fault in an effort to expose and map the new porphyry zone.

All assay work was performed by ICP (4-acid digestion) at ALS-Chemex labs of Vancouver, with gold done by standard fire assay methods. The samples sent to the lab were sealed with security tags for delivery to ALS-Chemex. Duplicate samples were inserted in each batch of samples and then checked to ensure proper quality assurance and quality control.
