Commencement of Well Testing

Coos Bay Coalbed Methane Gas Field, Oregon, USA

Curzon Energy Plc, the 100% owner of the 45,000 acre Coos Bay Coalbed Methane (CBM) Project, is pleased to announce that following the recent completion of workover operations, well testing operations on all five existing wells at Coos Bay have now commenced.

Highlights

· Testing started on the 29th of January 2018

· Contract awarded to Wood Group USA, specialists in CBM well operations, to assist with optimization of well testing and field production design

· All five existing wells (1-21, 9-21, 15-21, 13-15 and 16-16) in operation

· Recording of gas and water production volumes underway

· Wells showing signs of early gas production

· Gas rates anticipated to increase steadily with reservoir water removal

Early results of the well testing at Coos Bay confirm that the coals are fully saturated and do not require the intervention of a long-term dewatering processes, which is evident from the early indications of gas production.

In parallel with the start of the testing program, the Company is advancing the installation of a water disposal system, a gas sales contract and a trunk line connection for future gas sales. The Phase One development plan for Coos Bay remains on track to deliver first gas in Q2 2018.

Stephen Schoepfer, Managing Director of Curzon Energy said:

"We are delighted to have entered the testing phase of our Phase One development plan at Coos Bay where results thus far fall in line with our technical assumptions. We remain on track to deliver first gas in Q2 2018 and I look forward to updating the market on aggregate test results in due course."

About Coalbed Methane (CBM):

Coalbed methane gas (CBM) (or coal seam gas (CSG) or coal-mine methane (CMM)), is a form of natural gas extracted from coal seams or coal deposits. CBM is generated during the process of coalification which is the transformation of plant material into coal and is contained in the coal microstructure. Typical CBM recovery entails initially pumping water out of the coal to allow the natural gas to escape. Methane is the principal component of the natural gas from CBM production, which is typically made up of ~95 per cent methane and normally does not contain hydrogen sulphide or other sulphur compounds. Natural gas produced from CBM can normally be added to natural gas pipelines without any special treatment.

The United States has the longest history and greatest volumes of CBM production, however, other

countries such as Canada, China and Australia have increased production over recent decades.
