Sun River Energy, Inc. Announces Commencement of Drilling Operations in East Texas

Dallas, TX — (PRNewswire-FirstCall) — December 1, 2010 —Sun River Energy, Inc. (OTC:BB:SNRV). Sun River Energy, Inc. (the “Company” or “Sun River”) announces that it commenced drilling activities on November 30, 2010, in compliance with the terms of the Devon Energy Production Company, L.P. Farmout Agreement, which Sun River announced on October 27, 2010.

Sun River Operating, Inc. permitted the Neal Heirs #1 (API # 42-365-37706) on November 18, 2010 with the Texas Railroad Commission in District 6, Panola County, Texas. The well is permitted to 12,000 feet in the Carthage Field to test the Haynesville Shale. It is anticipated to encounter commercially productive zones in the Travis Peak and Cotton Valley geological formations.

Donal R. Schmidt, Jr., the Company’s CEO and President, stated, “Sun River’s Farmout with Devon called for drilling to commence no later than November 30^th. When you factor in the Thanksgiving Holiday, our team worked hard to timely spud this first well. This is a clear example of the quality and experience of our employees and their ability to work under time sensitive deadlines. It is always great to see a project come together when you have a short fuse. When we executed the Farmout, I was aware we would have to hustle to meet the initial deadline, but the confidence I placed in our professionals turned out to be well founded.”
