Brownstone's Second Piceance Basin Well Contains 254' Net Pay

TORONTO, ONTARIO--(Marketwire - Sept. 25, 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. (the "Operator"), have advised that the North Barcus Creek #2-12 well contains an estimated 254 feet of potential net pay. Casing has now been set to total depth. This result correlates positively with the 263 feet of potential net pay recently reported in the adjacent North Barcus Creek #1-12 well. Brownstone owns a 10% working interest in each of the #1-12 and #2-12 wells.

Brownstone and Dejour have engaged Gustavson Associates, Boulder Co. (Geologists - Engineers - Appraisers) to conduct a preliminary petrophysical analysis of the #2-12 well logs and in its report Gustavson disclosed that it is their interpretation that the reservoirs in the North Barcus Creek #2-12 and #1-12 wells are similar. Throughout drill operations the mud logs for each of the #2-12 and #1-12 wells showed strong evidence of reservoir gas. Both wells were keyed off the Federal #22-12 well drilled by Pacific Transmission Supply Co. in 1979, which reported 260' of possible gas pay.

Completion work on the North Barcus Creek #1-12 well has commenced. Results should be available within the next 10 days. Completion of the #2-12 will follow immediately thereafter.

Brownstone and its partners have also been advised by the Operator that it plans to drill additional wells on this 1,590 acre North Barcus Creek prospect, which forms part of the highly promising Rio Blanco Project consisting of a total of 5,554 acres. Brownstone holds a 10% unpromoted interest in these lands and all actual exploration expenditures. The Operator reports that the cost of drilling the #2-12 and #1-12 wells has been less than the original budgeted amount.

This North Barcus Creek lease block lies directly between a large Exxon lease block directly to the east and a large lease block owned by EnCana to the west. The Exxon lands host four recent natural gas resource discoveries drilled by Williams Cos. immediately offsetting the joint venture's leases. Exxon previously announced its intention to drill 1,000 wells on its leases in that area. Recently Conoco-Philips announced its intention to commence drilling of the first of 800 wells on the EnCana lands, which are now subject to a Conoco-Philips joint venture, early in 2008.

The North Barcus Creek prospect has the potential to initially drill up to 40 wells based on 40 acre spacing units with further down-spacing to 10 acre units in the future. Accessible pipeline facilities lay within one mile of the lease boundaries.

This 'Rio Blanco Deep' project is one of 23 separate exploration projects covering approximately 300,000 acres held by Brownstone (10% working interest) and its joint venture partners in the basins of Piceance/Uinta in Colorado/Utah.
