Guildhall Minerals Ltd.: Edmonton Sands Drilling Program Underway

CALGARY, ALBERTA--(Marketwire - July 17, 2009) - Guildhall Minerals Ltd., operating as Edge Resources (TSX VENTURE:EDE)(PINK SHEETS:GDMHF) ("Edge Resources" or the "Company") is pleased to announce that drilling operations are underway on the Company's first well of its previously announced Edmonton Sands drilling program. The well is being drilled conventionally and vertically to approximately 1,000 meters, targeting multiple zones within the Edmonton Sands group of formations using a "Super-Single" Automatic Drilling Rig (ADR). The same ADR will move to the Company's second location immediately upon completion of the first. The first well is expected to reach total depth during the upcoming weekend. The Company continues to seek additional drilling opportunities and licenses for new locations in the highly prolific Willesden Green and Gilby areas of Alberta.

"The weather has cooperated nicely and we were able to move the rig onto this environmentally friendly, 'zero-disturbance' surface location without incurring the additional cost or complication of constructing a surface lease," said Miles Johnson, VP Operations. "As always, we will continue to consider costs as one factor - not the only factor - in the total value equation."

The Company's President & CEO Brad Nichol commented, "We have our eyes and ears open for opportunities to expand on our drilling program and increase our working interest positions. This is in line with our corporate strategy of conserving capital in this price-depressed environment while adding only the highest quality Edmonton Sands prospects to our continually expanding land position."

About the Company:

Edge Resources is focused on the development of natural gas from the Edmonton Sands group of formations, a conventional, shallow gas group of reservoirs located in Central Alberta, Canada. The Management Team's very high success rate is based on the safe, efficient deployment of capital and a proven ability to efficiently execute in shallow gas, specifically the Edmonton Sands, which gives Edge Resources a sustainable, low-cost, competitive advantage.

The Alberta Government estimates that there is 44 trillion cubic feet ("TCF") of non-producing, shallow natural gas in Alberta. Edge Resources' Management Team has evaluated over 20,000 sections of land and has identified over 200 "five-star" sections. The Company's development program focuses on pursuing only these highly prospective "five-star" Edmonton Sands prospects.
