Bonaparte Receives Drilling Results on 2010 Drill Program on Rosy Property and Announces Option Grant

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 29, 2010) - Bonaparte Resources Inc. (TSX VENTURE:BON) ("Bonaparte" or the "Company") reports on its drilling results on the Rosy Property, Yukon. The Company has received all analytical results from three holes totaling 263.34 metres on gold and silver bearing vein targets on the property.

Drill holes Rosy-10-01 and 02 tested the R1 vein. Rosy-10-01 mostly cored competent metadiorite with varying degrees of clay alteration. R1 was intersected from 11.62 m to 14.52 m. At this depth, the vein was strongly weathered and altered. Mineralization comprised stringers of pyrite and chalcopyrite. This 2.9 m interval returned 0.259 g/t gold, 2.31 g/t silver and 1513 ppm arsenic. A hematite-rich alteration envelope is developed adjacent to the vein structure for up to two metres in core; however, the envelope did not return elevated values. Rosy-10-02 was a "scissor" hole to Rosy-10-01. This hole cored competent metadiorite with crosscutting dykes and varying degrees of clay alteration. R1 was intersected between 85.36 and 87.65 m. At that depth, R1 is composed of medium to dark grey quartz with minor carbonate veinlets containing weak to moderate disseminated pyrite and trace arsenopyrite. The mineralization flanks a syngenetic quartz-feldspar porphyry dyke. The intersection of R1 sub-surface, including the un-mineralized dyke, has a weighted average of 1.28 g/t gold, 2.63 g/t silver and 3382 ppm arsenic over 2.29 m. The table below contains analytical results from samples within this deeper intersection of R1.

Significant Drill Results – Rosy-10-02

Intersection (m) Length (m) Gold (g/t) Silver (g/t) Arsenic (ppm) Type
85.36 – 85.78 0.42 4.15 1.9 9070 Vein
85.78 – 87.09 1.31 0.008 0.1 38 Dyke
87.09 – 87.65 0.56 2.12 9.1 6940 Vein

Rosy-10-03 cut dominantly metadiorite with numerous shear structures hosting carbonate veins. R2 was intersected at 52.03 m and occurred as a series of parallel, narrow, carbonate veinlets with weakly disseminated pyrite. This hole did not return significant values for gold, silver or arsenic.

The drill program was supervised by Archer, Cathro and Associates (1981) Limited of Vancouver, British Columbia. The Company is currently reviewing its exploration plans for the Rosy Property.

The Company also announces that, on September 27, 2010, it granted an aggregate of 50,000 stock options to a director of the Company. Each option is exercisable at $0.45 per common share and is exercisable until June 22, 2015. The options vest immediately but may not be exercised until shareholders have approved of the Company's stock option plan at its next annual general meeting.
