Bonaventure Enterprises Inc.: Bonaventure Enterprises Inc.: Assay Results From the 2008 Drilling on K9 Uranium Property, Quebec

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 3, 2009) - BONAVENTURE ENTERPRISES INC. ("Bonaventure" or the "Company") (TSX VENTURE:BVT)(FRANKFURT:YQG) is pleased to provide shareholders with a complete listing of U3O8 assay results from the Company's 2008 diamond drilling campaign on the K9 Uranium Property ("K9") in Quebec's James Bay Mining District. K9 is located 125 km N-NE of the community of Radisson (Quebec) approximately 1,400 km north of Montreal (Quebec).

In 2007, Bonaventure completed the Phase 1 exploration program of surface uranium validation that included a high resolution airborne magnetic-EM-radiometrics survey, a ground spectral (or radiometric) survey, blasted bedrock sampling and assaying, and compilation, synthesis, Phase 2 planning and reporting. Bonaventure identified 5 significant airborne eU (or an Equivalent Uranium values taken from ground spectral measurements and not chemical assays) anomalies along a 7 km by 675 m combined "A" and "B" Zones showing the best uranium potential at the time. The uranium bedrock footprint at surface of the combined "A" and "B" Zones averaged 0.14% (2.80 lbs/ton) U3O8 with whereas spectral readings averaging 0.05% eU3O8 (1 lbs/ton).

Between May and November 2008, Bonaventure completed 58 diamond drill holes totaling 7,787 m of the Phase 2 delineation drilling of the "A" and "B" Zones. Uranium mineralization with grades greater than or equal to 0.008% (0.16 lbs/ton) U3O8 were intersected 45 drill holes. A total of 10 holes did not intersect significant mineralization and 3 holes were abandoned due to difficult drilling conditions. Some 5,916 drill core samples were assayed for Uranium by the ALS Laboratory Group(i). Significant U3O8 intervals are outlined in the following table (for intervals greater than or equal to 0.008% U3O8):

(i) Bonaventure has in place a rigorous QA/QC program consistent with
National Instrument 43-101 and using best industry practice. The ALS-Chemex
Laboratory of Val-d'Or (Quebec) and Vancouver (British Columbia) is
responsible for all of Bonaventure's assaying for the K9 Uranium Property
using the ME-MS61 (Mass Spectrometer) Elements Assay Protocol. Standards,
blank and duplicate samples were added for Quality Assurance and Quality
Control. 

Notes

- NSV - No significant values greater than or equal to 0.008% or greater
 than or equal to 0.16 lbs/ton U3O8
- ABAN - Abandoned drill hole due to difficult drilling conditions
- ND - drill hole not drilled due to poor access 
- Grey shaded intervals indicate assays were previously released on
 July 10, 2008
- 36 core samples from drill hole K9-08-09 were lost and subsequently not
 assayed
- 13 core samples from drill hole K9-08-16 were lost and subsequently not
 assayed
- 60 core samples from drill hole K9-08-58 were lost and subsequently not
 assayed

About Bonaventure Enterprises

Bonaventure Enterprises Inc. (TSX VENTURE:BVT) is a mineral exploration company focused on developing a diversified portfolio of uranium properties in Canada and promising gold properties in Nevada, with the goal of establishing National Instrument 43-101 compliant Mineral Resources in the near term.
