Basic Earth Updates Canadian Exploration Effort

Denver, Colorado, July 7, 2003—Basic Earth Science Systems, Inc. (Basic) (OTCBB:BSIC) reported today that Legent Resources Corporation (Legent), its wholly-owned Canadian subsidiary, has set casing on its second exploration effort in Canada, the Oungre 10-16-2-14W2. Setting casing in a well represents a decision to continue operations past the drilling phase to determine if commercial production can be established. The well, operated by Zinke & Trumbo Canada Corp, is approximately one mile south of the town of Oungre, Saskatchewan. Legent has a 12.5% interest in this well. In December 2002, Legent’s first exploration well, the Freestone 46C-18-9-6, was a dry hole.

“We are cautiously optimistic by the possibilities that this decision represents to Basic,” explained Ray Singleton, the company’s president. “Unfortunately, the Oungre well’s primary target, the Red River formation, was not adequately developed at this location and was incapable of commercial production. However, the Company has decided to set casing in order to further evaluate secondary objectives that were encountered during drilling operations.”

Basic is an oil and gas exploration and production company with primary operations in both the Canadian and U.S. portions of the Williston basin, south Texas and Colorado. Basic is traded on the “over-the-counter – bulletin board” under the symbol BSIC.
