15 January, 2010 - US Oil and Gas plc - U.S. OIL and GAS shares close first day of trading up 60% over the offer price

Dublin, Ireland, 15th January, 2010

U.S. Oil and Gas plc, Ticker: USOP, (USOIL), the oil and gas exploration company, has closed its first day of trading on London’s PLUS markets exchange at 8p sterling per share, representing a gain of 60% over the 5p Offer price.

The positive share performance is seen by the company as showing the market’s confidence in the company’s prospects and in the oil exploration sector in general.

U.S. Oil and Gas has an ongoing exploration program in Nevada, where the company holds a large lease acreage, having acquired the entire share capital of U.S.-based oil and gas company Major Oil International LLC. The primary assets of Major OIL International LLC are leases covering 21 sq kilometres in Hot Creek Valley, Nye County, Nevada.

"We're starting out with an excellent shareholder base and we're looking forward to an immediate start on ‘Eblana Phase 1’ – a six month exploration programme already planned in detail, says Brian McDonnell, U.S. Oil and Gas CEO. Exploration within the same geological feature as our claim in Nevada has already demonstrated huge reserves - the Covenant field has yielded over a billion barrels.”
