Resource Potential of Brownstone Piceance/Uinta Properties Pegged at 5.3 TCF Natural Gas and 2 Billion Barrels of Oil

TORONTO, ONTARIO--(CCNMatthews - Nov. 27, 2006) - Brownstone Ventures Inc. (TSX VENTURE:BWN) today announced that it has received reports evaluating the resource potential of its Dejour/Retamco joint venture properties in the Piceance and Uinta Basins (see press release dated June 26, 2006) (the "Retamco JV"). The report, authored by Houston, Texas based W.D. Von Gonten & Co., Petroleum Consultants (dated October 24, 2006) states there is a resource potential for 4.107 Trillion Cubic Feet (TCF) of natural gas and 2.055 Billion Barrels of Oil to the 100% interests. Brownstone holds a 10% participating interest. Brownstone is assigning this potential to the category of 'undiscovered' resources pursuant to NI 51-101 requirements. Additionally, Williams & Associates, Petroleum Consultants, of Midland, Texas calculates the potential resource of associated Coal Bed Methane to be in excess of 1.2 TCF. Brownstone is assigning this potential to the category of 'prospective' resources, again pursuant to NI 51-101 requirements.

The Von Gonten report, prepared for Retamco Operating Inc., partner/operator of the Retamco JV, and a significant shareholder of Brownstone as a result of the Retamco JV, assigns resource potential to 14 of the 18 project areas within the Piceance and Uinta Basins. The remaining project areas will be reported shortly.

Subsequent to the report, Delta Petroleum (NASD:DPTR) reported a significant discovery in the Paradox Basin (Southern Uinta), a project area in which Brownstone holds a 10% interest in 24,500 acres of lands previously unvalued within the Von Gonten report.

Brownstone owns a 10% participating interest in the gas resource potential and 10% participating interest in the oil resource potential as discussed in these reports. Certainty of the economic viability of this resource potential at this time is not yet determined, based on COGE standards, discussed below.

The Retamco JV, which includes Dejour Enterprises Ltd. (TSX VENTURE:DJE), Retamco Operating Inc., and Brownstone has requested that W.D. Von Gonten & Co. update their report and, where appropriate, establish proven undeveloped reserves (PUD) in areas where extensive drilling and production activity have taken place. This report is expected early in 2007.

Brownstone has been advised by Retamco that drill permits are expected to be approved in December by the Colorado Bureau of Land Management (BLM) that will allow the drilling of four 12000' wells proposed on the Barcus Federal Prospect, a 3 section -1920 acre lease block that forms part of the Retamco JV Rio Blanco Project Area. A drill rig currently operating on adjacent lands will be available early in January 2007. Additional permits should be forthcoming early in the New Year.

Retamco further advised that Exxon Mobil has recently completed for production 4 wells on acreage surrounding this lease block, each at flow rates greater than 2.5 million cubic feet per day, from the Mesa Verde sand, the major blanket resource zone being exploited in the Basin. Wells in this area are usually drilled on 10 acre spacing units.

In a recent release (dated October 15, 2006), Exxon disclosed plans to move 14 rigs to this project, build a town site for 600 personnel, and drill 1000 wells over the foreseeable future to exploit the reserves on these lands. Retamco also advised that Williams Co., a major US operator of pipelines, is in the final stages of completion of a 36" gas line able to transport large quantities of gas from this area beginning early in 2007. This pipeline is located in close proximity to the Barcus Federal Prospect, with available capacity. Authorization for expenditures (AFE's) are now being prepared.

About the Piceance/ Uinta Basin

The Piceance/Uinta Basin, heart of the Rockies, is part of the most active gas production region in the US, where proven reserves and daily production rates now exceed the Gulf of Mexico, according to the Oil & Gas Investor (November 2006). Currently over 100 rigs are active in the Basin - 100% utilization.

"Consulting and research firm Wood Mackenzie says the top 34 E&P companies working in the region today could drill as many as 43,000 wells in Rockies in the next five years...with planned expenditures of nearly $25 billion during that timeframe...drawn by the vast reserve potential." (Oil & Gas Investor, November 2006).

"This Piceance/Uinta Basin Project represents another direct oil and gas investment designed to provide both high impact and leverage to Brownstone's investments. We are very pleased with the proposed activity on and adjacent to the Retamco JV project lands and expect the value of this investment, both land and resource, to continue to escalate", stated Mr. Inwentash, President & CEO.
