Creso Announces Results of Surface Sampling at West Shining Tree

MONTREAL, QUEBEC -- (Marketwire) -- 09/09/11 -- Creso Exploration Inc. ('Creso' or the 'Corporation')(TSX VENTURE: CXT)(OTCQX: CRXEF)(FRANKFURT: C3X) is pleased to announce the results of surface grab and channel sampling at the Corporation's Moore-McDonald, Downey, Gibson, Bennett, and Kubiak properties in the West Shining Tree district of NE Ontario (Figure 1). Creso's management is very encouraged by the fact that 15 samples exceed 10 g/t Au, 9 samples exceed 20 g/t Au and 5 samples exceed 30g/t Au.

Table 1 reports results with gold values greater than 1 g/t, which occur in 65 of 297 samples taken from these properties, with the highest grade results as follows.

a) 266.0 g/t Au and 73.6 g/t Au in grab samples from Downey (previously
   reported in the May 27, 2011 Press Release);
b) up to 103.0 g/t Au in a grab sample from Moore-MacDonald;
b) 56.8 g/t Au in a grab sample from Downey;
c) 20.1 g/t Au in a grab sample from Gibson;
d) 10.89 g/t Au in a grab sample from Bennett, and
e) 5.06 g/t Au in a grab sample from Kubiak.

Selective excavation of large-volume exploration samples from each of these properties is being planned for the coming weeks, in the expectation that this technique will provide a more accurate measure of determining the average grade of gold over wide areas of mineralization.

Creso geologists are encouraged by the large number and broad distribution of high grade assays throughout the West Shining Tree area, where gold appears to be locally controlled by quartz-carbonate-sulfide veins and veinlets that range in width from hairline whisps to 20 - 40 centimeters. These veins tend to be contained within extensive East-West shear zones, particularly at intersections with Northerly trending structures, and sometimes cut pre-existing bull-quartz veins.

Moore-MacDonald and Gibson properties

The Moore-MacDonald property in Macmurchy Township appears to display the most consistent trends of high grade gold assays (Figure 2: http://media3.marketwire.com/docs/MooreMacdonaldproject2.pdf), but the Gibson property in Asquith Township hosts what may be the biggest shear zone in the entire Shining Tree district. This shear zone is recognized in the field for over 8 kilometers in strike length and up to 1.5 kilometers in width. Sampling at Gibson was carried-out principally to test CARDS (Computer Aided Resource Detection System) anomalies that were developed on contract by Diagnos Inc. (TSX VENTURE: ADK), a leading company in the use of artificial intelligence and advanced knowledge-extraction techniques. Working in tandem with Creso personnel, Diagnos geologists sampled quartz veins in shear zones at the Gibson property from 112 locations, six of which returned assays above 1 g/t Au, including higher grade assays up to 20.1 g/t Au, 10.7 g/t Au, and 7.16 g/t Au (Figure 3: http://media3.marketwire.com/docs/GibsonDiagnosSamples.pdf). An East-West zone of mineralized shears north of Moorecamp Lake appears to be particularly favorable for follow-up examination. Similarly, samples extending westward from the old Bennett mine in Macmurchy Township display a consistent trend of plus-3 g/t Au assays that demand further testing (Figure 1: http://media3.marketwire.com/docs/RegionalMap1.pdf & Table 1: http://media3.marketwire.com/docs/TableCreso.pdf ).

Downey property

Channel sampling at the Downey property in Asquith Township that was meant to test extensions of previously reported high grade gold mineralization resulted in multiple elevated assay values up to 34.01 g/t Au over one meter and an adjoining sample of 7.16 g/t Au over 0.5m, where the original surface grab ran 4.71 g/t Au (Table 1: http://media3.marketwire.com/docs/TableCreso.pdf). In an attempt to quickly test below the high grade (266 g/t Au) zone at Downey, a Winkie Drill returned one small-bore core sample from approximately 11.6 meters vertical depth with a gold value of 1.68 g/t over 0.5 meters.

Additional large-volume sample testing is also being considered in the Tyranite and Minto zones in the east part of the Shining Tree District, in addition to possible extension of deep drilling in those areas in the near future.

This Press Release has been reviewed and approved by Mr. Alex Kutah, M. Sc, P. Geo., the Qualified Person under National Instrument 43-101.

Creso Exploration QA/QC procedures follow standard industry practices. Sealed core boxes are transported twice daily from the drill rig to the core logging facility by qualified Creso personnel. Core is logged and prepared for sampling in a secure building. Sample intervals are selected according to geologic contacts, visible mineralization, and alteration. Drill core is cut along a center line using a typical circular rock saw designed for core cutting. Sampled core is placed into sample bags, sealed and shipped to an assay lab that follows the ISO 9000 series of Quality Management standards. All samples were analyzed for gold and other trace elements at ALS Group Ltd. laboratories by standard industry procedures. These procedures include gold by fire assay-AAS finish, with follow-up gold analyses by fire assay-gravimetric finish and/or metallic screen. Multi-element analysis is done by ICP (ME-MS61) using a four-acid digestion.

Blank and certified standard samples are routinely submitted with all sample batches sent to the lab for assay. In addition, replicates, duplicates, and field duplicates are routinely included in sample batches. Samples with visible gold are analyzed with procedures designed to reduce the variability of the sample results. And finally, samples are routinely sent to other labs for additional checks.

About Creso

The Corporation's principal mining exploration holdings are located in the Shining Tree mining camp of Northern Ontario within 100 km of the Timmins and Kirkland Lake mining camps, and additional interests are held in base metal properties in Guatemala.
