Guildhall Minerals Ltd.: First Well Completed, Second Well Underway, Drilling Program Extended With Addition of Two New Wells

CALGARY, ALBERTA--(Marketwire - July 21, 2009) - Guildhall Minerals Ltd., Operating as Edge Resources (TSX VENTURE:EDE)(PINK SHEETS:GDMHF) ("Edge Resources" or the "Company"), is pleased to announce that it has completed drilling operations on the Company's first Edmonton Sand well. The well was drilled vertically, without any incidents, to a depth of 966 meters and encountered multiple zones within the Edmonton Sands group. The Company has utilized the same "Super-Single" Automatic Drilling Rig (ADR) which performed very well and has now moved to the second licensed location in this drilling program. Drilling has already commenced on the second well, which is anticipated to be completed by mid week.

Furthermore, the Company is pleased to announce that it has doubled the size of this drilling program through the addition of two Edmonton Sand locations. The additional wells are located in the highly prolific Willesden Green area of Alberta.

With this expanded program, the Company will seek to reduce the costs of this program even further by utilizing greater economies of scale, which these additional locations will allow. The Company is pleased that the same ADR and crew will be available to drill the additional locations.

The Company has quickly modified its completion program and now intends to perforate all four wells after the entire drilling program is completed, in a continued effort to extract more efficiency from its operations.

Commenting on the rig and crew used, Miles Johnson, VP Operations noted, "Having used this extensively in the past, we were very pleased with the ADR equipment and personnel. Likewise, we demonstrated our company's ability to turn on a dime when necessary to create additional shareholder value. Adding two wells on the end of our program as quickly as we did was no small job. Few, if any, companies could have reacted as quickly as we did, enabling us to take full advantage of the economies of scale that a program double the size of the original can offer."

Brad Nichol, President and CEO added, "The logs on the first well indicate slightly more net pay than we originally expected, indicating this well may be better than anticipated. Our technical team will continue to raise the bar within the prolific Edmonton Sands area with the extended drilling program."
