24 February, 2012 – U.S. Oil & Gas Plc – Acquisition of Additional Lease Acreage

U.S. Oil and Gas Plc.
(“U.S. Oil” or the “Company”)
Acquisition of Additional Lease Acreage

U.S. Oil and Gas plc (PLUS: USOP), the oil and gas exploration company
with its main asset in Nevada,USA, is pleased to announce it has acquired
additional lease acreage in Hot Creek Valley. Through its wholly owned subsidiary,
Major Oil International LLC, U.S. Oil has leased two new lots,
totaling 5,000 acres and contiguous with existing acreage, from the
Nevada Bureau of Land Management. The company’s total acreage position in
Hot Creek Valley is now 15,738 acres (approx. 64 sq. km.).

U.S. Oil’s intention in acquiring the new leases is to enhance the Company’s
Nevada asset, but it does not foresee expending significant exploration effort
in advance of the currently planned drilling programme.

U.S. Oil’s CEO Brian McDonnell said, ‘These acquisitions materially increase our
exposure to the Hot Creek Valley play and consolidate our position. We know
that oil resources we have already located extend into part of the newly leased
area, and we believe the new acreage offers exciting exploration and drilling
opportunities.’

THE DIRECTORS OF THE COMPANY ACCEPT RESPONSIBILITY FOR THE CONTENTS
