CRESO EXPLORATION INTERSECTS 65.7 METERS OF 18.2 G/T G AND 79.6 METERS OF 4.61 G/T GOLD IN HOLE #2 ON THE MINTO PROJECT
Creso Exploration Inc. (formerly Willowstar Capital Inc.) has learned that the TSX Venture Exchange approved the listing of the common shares of the corporation following the closing of the qualifying transaction (see news in Stockwatch on June 3, 2010). The trading of the Creso Exploration shares under the new symbol, CXT, will commence on June 10, 2010.
Creso also announces drill results from the Minto project located halfway between Timmins and Sudbury in Ontario and approximately 30 kilometres southwest of NorthGate Minerals Corp.'s Young-Davidson gold deposit. The 2009 NQ diamond drilling two-hole program best results are from hole No. 2:
18.2 grams per tonne Au over 65.7 metres from 49.3 m to 115 m, (7.9 g/t Au if cut at 31.1 g/t), including 33.2 g/t Au over 25.7 metres from 49.3 m to 75 m (10.4 g/t Au if cut at 31.1 g/t);
4.61 g/t Au over 79.6 metres from 132.4 m to 212 m, (3.35 g/t Au if cut at 31.1 g/t), including 20.7 g/t Au over 10 metres from 202 m to 212 m (11.5 g/t Au if cut at 31.1 g/t).
In both zones, sampling is continuous with sample widths varying from 0.41 m to 1.28 m (averaging one m) and grades varying from 487.9 g/t over 0.42 m to 0.03 g/t over 0.73 m. From surface geology the upper zone presents a true width of 30 metres. The bottom zone is new and no true width has been determined yet. According to JVX Ltd., the downhole geophysical interpretation completed on the Minto property indicates that the mineralized body extends in a northwest-to-southeast direction at a depth of 50 to 170 metres and is open at depth. The corporation will drill a step-out hole for the purpose of further defining the location of the body using more downhole geophysics. Hole No. 1, located 30 m north of hole No. 2 gave a value of 10.4 g/t over 0.5 metre from 31.6 m to 32.1 m, but failed to intersect the target zone.
According to Mike White, PGeo, who supervises the project, gold is present in three different host rocks determined by visual and lithogeochemical analysis, namely: felsic rocks, mafic rocks and intermediate volcanic/breccias, within a potassium-enriched northerly structural/quartz vein system, approximately 30 m in width according to surface geology.
The Minto project is part of a substantial land package that has been consolidated by Creso over the last 12 months representing 280 square kilometres and which also includes the Tyranite mine and the Duggan zone.
The Tyranite mine is located two kilometres north of the Minto project on a north-to-south structure and has been identified over a strike length of more than one kilometre. A shaft down to 1,000 feet and more than 4,500 feet of drifts on five levels explore the mine workings. The Tyranite mine shows strong geological similarities and characteristics to the Duggan zone such as a north-to-south trend located in proximity to a major intrusion.
Between 1939 and 1942, 210,300 tons grading 0.147 ounce per ton (five g/t) Au were produced. An inferred historical resource of 472,000 tons (428,000 metric tonnes) grading 6.9 g/t Au is estimated to exist in the underground workings (White 2007)**.
A current 3-D geological modelling of all Tyranite available data indicates that three out of five lenses plunge at depth and that the central and northern mineralized zones present a true width between 70 to 80 metres, the central one being still open at a depth of 350 m.
The Duggan zone, located one kilometre to the west of the Tyranite zone, has the same characteristics: north-to-south trend located on the edge of a major intrusion. Creso, in its 2007 drilling campaign, has discovered a mineralized zone with sample grades in excess of one g/t Au over an average width of 80 metres and a strike length of 450 metres which appears to be open to the north at a depth of more than 200 metres.

** Creso has not analyzed the assay results of the previous exploration results to verify the resource database and therefore, this historical estimate should not be relied upon. The previous estimate is not a current estimate made in compliance with National Instrument 43-101 and the authors are not treating this historical resource estimate as a resource or reserve within the meaning of National Instrument 43-101. The authors view this historical estimate as a conceptual indication of the potential size and grade of the resource.
Exploration program
In May, 2010, borehole induced polarization (BHIP) surveys were done on the Tyranite and Minto properties. Results from the Tyranite hole are not yet available. Three-dimensional conductivity and chargeability models from borehole gradient IP data have been calculated for holes M-0901 and M-0902 on the Minto property.
The corporation has completed downhole geophysical testing on the MacMurchy property and intersected 7.4 per cent nickel and two g/t platinum and palladium over one metre in hole D6-07 confirming the nickel potential of the area. The MacMurchy property is located in the southwest corner of the MacMurchy township about 10 kilometres south-southwest of the Minto property.
The corporation is currently evaluating bids for an agreement for a 200-kilometre low-level airborne (Mag, VLFEM and radiometric) geophysical survey to cover the Minto, Tyranite and Duggan zone on a 30-metre spacing in order to define geological structures and mineralized zones. Upon completion of the geophysical survey, the corporation will undertake a 5,000-metre drill program on the Minto, Tyranite and Duggan properties.
Samples were assayed at the facilities of Swastika Laboratories of Kirkland Lake (Swastika, Ont.), a certified and accredited laboratory by a standard fire assay method. All samples with greater than one g/t Au were reassayed by a pulp and metallics method. Above interval values are weighted averages.
The corporation's principal mining exploration holdings are located in the Shining Tree mining camp of Northern Ontario within 100 kilometres of the Timmins and Kirkland mining camps and additional interests are held in base metal properties in Guatemala. Creso has approximately $4-million in working capital with no debt.
