Brownstone Ventures Inc.: Piceance Basin Well Contains 263' Net Pay

TORONTO, ONTARIO--(Marketwire - Sept. 5, 2007) - Brownstone Ventures Inc. (TSX VENTURE:BWN) ("Brownstone") announces that its joint venture partners, Dejour Enterprises Ltd. (TSX VENTURE:DEJ)(AMEX:DEJ) ("Dejour") and Retamco Operating Ltd., have advised that the H & P Rig #159 has been released from the North Barcus Creek #1-12 well where logging operations and the setting of production casing were successfully completed. Brownstone (together with Dejour) engaged Gustavson Associates, Boulder Co. (Geologists - Engineers - Appraisers) to conduct a preliminary petrophysical analysis of the #1-12 well logs, who have reported to Brownstone and Dejour that it is their interpretation that there exist reservoir properties consisting of an estimated 263 feet of potential net pay with average porosity of 10%. Throughout drill operations the mud log showed strong evidence of reservoir gas.

The H&P Rig #159 is in the process of relocating and rigging up to drill the nearby North Barcus Creek #2-12 well (within approximately 1,800 feet of the #1-12 well) to be deepened to a projected TD of 11,425'. Drill operations should be concluded around the end of September 2007.
