GXG Resumption of Trading

26 May 2015

U.S. Oil & Gas Plc (GXG London: USOP, OTC New York: USOPY), the oil and gas exploration company with assets in Nevada, is pleased to announce that GXG Markets restored trading in the Company's securities at 9.00 CET, Tuesday 26th of May 2015. This action follows the completion by GXG Markets of its investigation and the findings of an independent Due Diligence Report that confirmed that the Company had not misled the market.

In a previous announcement, the Company welcomed GXG Markets' appointment of an independent Due Diligence consultancy. The Due Diligence Report encompassed the history of the Company from September 2011, its communications with the Market over a two year period, its discovery of oil in Hot Creek Valley, as well as its governance and administrative processes.

The Company believes that the GXG Markets' investigation was prompted by unfounded allegations made to GXG Markets, including anonymous internet allegations. These allegations were contrived, vexatious and utterly without foundation.

US Oil and Gas CEO Brian McDonnell said: 'With the restoration of trading and the independent Due Diligence Report, we can now move forward vigorously with our corporate and exploration agendas.'
