Notes to Editors

US Oil and Gas plc is a PLUS (Ticker: USOP) listed oil and gas exploration company with a strategy to identify and acquire oil and gas assets in the early phase of the upstream life-cycle and mature them into marketable opportunities for the medium and large-sized oil companies. The Company’s main asset is in Nye County, Nevada where it holds the entire share capital of the US-based company Major Oil International LLC. Major Oil has acquired, and intends to acquire, rights to exploration and development acreage in two high potential resource areas in Hot Creek Valley, Nye County, adjacent to the oil and gas rich Railroad Valley area of Nevada, both of which are part of the Sevier Thrust of central Nevada and western Utah, USA.

The IPDS Passive Seismic Survey results reported on 26th February 2010 showed high DHI (Direct Hydrocarbons Indicator) readings for Section 2 (North), with DHI of 0.96. This section was identified as the likely first well drilling target and which has now been staked and prepared for the first well drilling campaign. DHI readings for Section 3 (East) of up to 0.59 DHI, led USOIL to nominate this section as its likely second well-drilling target. Geochemical results for Eblana Phase I indicates five clearly defined hydrocarbon reservoirs, with excellent correlation with IPDS and gravity/magnetic survey results.

The final shortlist of well-drilling contractors has been drawn up and the result of the selection process will be announced in due course.
