· Reserve migration includes first-time booking of proved 1P (P90) reserves volumes on G3E's GGZ Block totalling 5.2 Bcf valued at US$33.7M

The estimates of reserves have been provided by independent reserve engineers Netherland Sewell and Associates Inc. (NSAI) on eight coal bed methane exploration and development blocks namely GSS, GCZ, GSN, GQY-A, GQY-B, GGZ, GFC and GPX.

Randeep S. Grewal, Chairman and Founder commented:

'Our annual independent updated reserves report reinforces the potential of our quality and well positioned asset base in China. The reduction in the consolidated reserve values are as a result of the US$613m cost recovery and removal of Area 2 in the GSS Block as a result of the Supplementary Agreement with CNOOC.

'The GGZ Block is progressing well towards development, with first gas anticipated this year as planned. Once in production, the GGZ Block will be the next asset to be ring-fenced for sale, farm-out or a dividend in specie, as per producing blocks, GSS and GCZ which are presently planned to be included in the Hong Kong IPO of GDG.

'Our continued primary focus is to explore and develop our remaining exploration blocks and dis-risk the development profile across our vast acreage with our partners CNOOC, CUCBM, CNPC and PetroChina.'

G3 Exploration Ltd.; Exploration & Development Assets

Reserve volumes reported as at 31 December 2017 include first-time booking of our first proved (P90) 1P reserve volumes on the GGZ development asset located in the Guizhou Province, which is an initial step towards the commencement of large scale commercial gas sales from the block. In accordance with the plan announced on 20 December 2017, the migration of resources to proved reserves reflects the following achievements at GGZ during 2017:

· Successfully completed 12CBM production wellsin multiple coal seam reservoirs

· Continuous and stable pilot commercial production from seven CBM production wells

· Finalised initial pilot gas sales programme for current gas producing wells

Guizhou Province is located in southern China and currently sources the majority of its gas needs by pipeline from other provinces. As such, prices in Guizhou attract a transportation premium to encourage the delivery of gas to the province. It is expected that gas sourced and produced directly in Guizhou will also benefit from this premium as the premium is a factor in determining city-gate end user pricing, making these assets even more desirable.

Green Dragon GasLtd.; Production Assets

GSS Block and GCZ Block are located in the southern Qinshui Basin, Shanxi Province, China, which is one of the two areas in China where the initial gas in place (GIIP) estimates are over 3,500 Bcf according to NSAI. GDG holds 47% and 60% of the participating interests under the Cooperation Agreement (for GCZ Block) and the PSC (for GSS Block), respectively.

The 2017 reserve report includes all 1,453 wells operated by GDG, CNOOC and PetroChina across these blocks in which the company has varying equity interests.

Average wellhead price used in the reserves evaluation for year 2018 was US$9.38/Mcf (5% escalation thereafter) at the production blocks, inclusive of Government subsidies. Changes in PV10 values in year over year comparison are mainly as a result of:

· Inclusion of CNOOC GSS Block cost recovery balance of circa. US$613 million

· Removal of Area 2 coal seam 3 from GSS Block according to the GSS Supplementary Agreement signed in 2017

The estimates in this announcement have been prepared in accordance with definitions and guidelines set forth in the 2007 Petroleum Resources Management System (PRMS) approved by the Society of Petroleum Engineers. The information in this announcement pertaining tothe Company reserves have been reviewed by Hassan Sindhu, the Company's Director of Resources Management,who holds a Petroleum Engineeringdegree from the China University of Petroleum.
