Tri-Valley Rapidly Accelerating Projects Development

Tri-Valley Corporation (AMEX: TIV) announced that nothing adverse to the Company's operations has occurred to justify the drop in its stock price during the past few days and, in fact, its oil production trend is strongly up as reported in its Annual Shareholder Meeting last Saturday.

Yesterday's downturn occurred with a large block of stock being sold just before the closing bell, distorting the total trading volume of the day which amounted to less than one percent of the outstanding shares.

Historically, Tri-Valley shares recover strongly from these kinds of market induced pressures even though the dip in share price can force sales from margin accounts and stop loss orders at the time. We are devoted to generating new wealth from new oil and gas production and are working with properties of exceptional potentials in that regard, said F. Lynn Blystone, president and chief executive officer.

The well was drilled to 7,000 ft. and logged pay in two natural gas filled sands in the Nortinville formation at 3,350 ft. and 3,800 ft. The deeper Starkey Channel was penetrated at 6,500 ft. and encountered 26 ft. of high porosity and permeable natural gas filled sands.

“The Company had drilled four commercially productive wells to the shallower Nortinville formations on Andrus Island, noted Donald Hosmer Royale Energy CEO. This was the first attempt to drill to the deeper Starkey objective. The deeper objective in the well was higher risk but because of the potential upside the Company felt the risk was justified.
