22 February, 2012 – U.S OIL And GAS Plc Competent Person’s Report

U.S. Oil & Gas Plc.

(“US Oil” or the “Company”)

Competent Person’s Report

U.S. Oil & Gas plc (PLUS:USOP), the oil and gas exploration company with its main asset in Nevada, USA, is pleased to announce the completion of a Competent Person’s Report (CPR) from independent petroleum consultants Forrest A. Garb & Associates (FGA). The CPR follows the interpretation of all currently available data related to US Oil’s original (pre-December 2011) lease area at Hot Creek Valley. U.S. Oil & Gas has a 100% interest in the property through its wholly owned subsidiary Major Oil International LLC.

Based on a detailed review and using the Petroleum Resources Management System (SPE-PRMS), Forrest A. Garb & Associates calculated gross Prospective Resources and Net Present Value for the prospect.

Highlights:

Geological Assessment of Drilling Target:

* Major Oil used a rigorous process to identify possible oil and gas accumulations.

* No single data analysis is taken as a basis for drilling the well.

* The subsurface structure appears to be a continuity of the oil producing welded volcanic tuffs found
in Railroad Valley.

* The dominant trap type is structural given the faulting and compartments in the area.

* According to SPE-PMRS guidelines, the “prospect” is sufficiently well defined to be a drilling target.

Best Estimate Prospective Resources (50% probability) based on SPE-PRMS:

* Gross Prospective Resources amount to 189 MMSTB.

* Gross estimates for recoverable oil are 67 MMSTB.

* Estimated Net Present Value (un-risked) for the Prospective Resources is $514 MM for a ten year projection discounted at 10% per year.

CPR Summary
FGA based their analysis on all available data for US Oil’s original (pre-December 2011) lease area reviewing gravity data, magnetic data, satellite imagery, 2-D seismic data, passive seismic data, and various consulting firms’ interpretations provided by Major Oil. Based on review of the materials provided, FGA concluded that Major Oil used a thorough, rigorous process to identify possible oil and gas accumulations and mitigate risk. They are of the opinion that activities proposed in this exploration program are consistent with current practices in oil and gas exploration, and FGA believes that this Prospect is sufficiently well-defined to be a viable drilling target.

Financial Model and Net Present Value
FGA reviewed the assumptions and cash flow calculations used in the present value estimate for a financial model provided by Major Oil. The model was based on a 15 well exploration plan with wells being drilled over a two year period, a capital investment of $40 MM, and oil production and cash flows projected over a ten year period. This 15 well project has an estimated present value discounted at 10% per year of $514 MM (unrisked) for the ten-year projection. FGA agrees with the procedure and results of these economics based on the assumptions described.

US Oil and Gas CEO Brian McDonnell said, “This comprehensive independent assessment of the prospectivity of our Hot Creek Valley property has confirmed its considerable potential, endorsed our exploration process and validated our selection of drilling targets. We now look forward to starting our drilling campaign subject to final approval by US federal authorities.”

A copy of the letter from Forrest A. Garb & Associates summarizing its conclusions will be made available on the Company website www.usoil.us.
