INDONESIA UPDATE

Range refers to the announcement titled 'Indonesia Operational Update'published on 22 March 2018. Range confirms that the reported forecast production figure of 200 bopd (gross) has been extrapolated from the Company's 1P reserve estimates of 279,055 barrels (gross).

Based on Range's initial 23% indirect interest in the Indonesia project, the net forecast production to Range is estimated at 46 bopd and net 1P reserves of 64,183 barrels.

Range does not consider its interest in the Perlak field in Indonesia to be a material oil and gas project for the purposes of the ASX Listing Rules in light of the significance of its oil and gas assets in Trinidad.

Reserves cautionary statement

Oil and gas reserves estimates are expressions of judgment based on knowledge, experience and industry practice. Estimates that were valid when originally calculated may alter significantly when new information or techniques become available. Additionally, by their very nature, reserve and resource estimates are imprecise and depend to some extent on interpretations, which may prove to be inaccurate. As further information becomes available through additional drilling and analysis, the estimates are likely to change. This may result in alterations to development and production plans which may, in turn, adversely impact the Company's operations. Reserves estimates and estimates of future net revenues are, by nature, forward looking statements and subject to the same risks as other forward-looking statements.

Note relating to statutory disclosure of significant shareholdings

All shareholders who are holding (directly or indirectly), 3% or more of the issued and outstanding Ordinary Shares are requested to notify the Company without delay of any changes to their holding which increase or decrease such holding through any single percentage. Likewise, shareholders who acquire 3% or more of the issued and outstanding Ordinary Shares are requested to notify the Company without delay.

Glossary - SPE Definitions

Bopd- barrels of oil per day

Proved reserves- quantities of petroleum, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from known reservoirs and under defined economic conditions, operating methods, and government regulations. Probable Reserves are those additional Reserves which analysis of geoscience and engineering data indicate are less likely to be recovered than Proved Reserves but more certain to be recovered than Possible Reserves.

1P- Proved reserves. Probability of success 90%.
