Boulder Mining Corporation - Opal Energy Inc.

Boulder Mining Corporation through its U.S. subsidiary Opal Energy Inc. offers an aggressive, disciplined and results-oriented vehicle to invest in the U.S. E&P sector with a particular focus on natural gas exploration targets in South Texas. The business strategy is to build asset value through the drill bit, growing a production platform upon which will be superimposed some remarkable, high-impact exploration opportunities. Drilling inventory will be continuously enhanced by the implementation of a series of proprietary 3-D seismic shoots. Opal has attracted funding partners for an initial US$16 million South Texas exploration package that calls for drilling 10 wells and completing a 75 sq. mi. seismic shoot over the next 9 to 12 months. Interpretation of the seismic shoot is ultimately expected to uncover dozens of new high-quality drilling prospects starting in Q3-2007.

Effective November 21 or so, Boulder intends to change its name to Opal Energy Corp, request a new trading symbol and unveil its new website under the address www.opalenergy.ca.
