A. Lee Graham Reporter The U.S. Securities and Exchange Commission has temporarily suspended securities trading activity for Norstra Energy Inc. after the Southlake company said unnamed individuals have been promoting its stock. “We seek to clarify that we have not engaged in any such activity and have no connections to, or relationships with, anyone who would be engaging in the promotion of our stock,” reads part of a company news release. The promotional items in question include projections that the company said are not based on genuine analysis of its operations. “As an exploration stage enterprise, our focus must remain on developing our property interests to establish a commercially viable hydrocarbon resource,” the company said. “This is where our attention and funds will remain focused, and we have not, and do not currently intend to, expend funds on stock promotional activity.” The company plans to resume stock trading activity on July 10, 2013. More information is available at www.norstraenergy.com. Norstra Energy Inc. is an oil and gas exploration company with interests spanning more than 10,000 acres in the Bakken Shale in Montana. lgraham@bizpress.net
