OVER 600% INCREASE IN 1P HELIUM RESERVES
Domestic natural gas and helium producer Renergen is pleased to announce a significant
increase in methane and helium Reserves at its flagship Virginia Gas Project (“Virginia”).
Following the recent successful drilling campaign and as part of the Company's ongoing
assessment and development of Virginia, Renergen commissioned international Reserves and
Resources accreditation agency Sproule to estimate the reserves and resources of methane and
helium within the Company's Virginia Production Right area as at September 1, 2021 (“Updated
The Production Right area covers 187,000 hectares in the Free State in South Africa around the
towns of Welkom, Virginia and Theunissen (Figure 1). Renergen holds a valid licence over the
area until September 2042 (“Production Right”) and also holds 100% of the economic interest in
the Production Right.
Following completion of the estimated upgrade, Sproule has upgraded the methane and helium
Reserves at Virginia. Impressively, 1P helium reserves have increased by 620% to 7.2Bcf and
1P methane reserves have increased by 427% to 215.1Bcf. The results are very significant to
the Company, its shareholders and importantly, highlights the exciting potential of Virginia to be
a globally significant supplier of helium.
The headline numbers as calculated by Sproule are set out in the table below, together with a
comparison of reserves prior to the recent round of drilling. A full copy of the report can be found
on the Company’s website (https://www.renergen.co.za/2021-update-on-the-estimation-of-
gas-field-in-the-free-state-of-the-republic-of-south-africa-as-of-september-1/). It includes
estimates of Contingent Resources and Prospective Resources of both methane and helium, in
addition to Proved, Probable and Possible Reserves and their estimated Net Present Value at
various discount rates.

Commenting on the excellent growth in Reserves at Virginia, Stefano Marani, CEO of Renergen
said “The significant growth in methane and helium Reserves at Virginia is a major milestone for
the Company and confirms Virginia as a world-class helium project. After more than two years of
hard work by the exploration team, the results speak for themselves, and I would like the thank
the whole team for their dedicated effort and focus.
“We have and continue to work towards ensuring Virginia is well-placed to supply helium into a
growing and constrained market. Increasing our 1P helium reserves by over 600% since March
2019 is a great step forward in achieving this goal and importantly, highlights the enormous
potential of Virginia to become a significant helium supplier to not only South Africa but globally
as well. Additionally, an estimated 400 petajoules of methane at 2P also positions the Company
exceedingly well to become an integral part of South Africa’s energy mix.
“2021 has been an excellent year for Renergen, with several milestones achieved and we look
forward to firmly ending the calendar year. 2022 is shaping up to be even more exciting as we
commence production from the Phase 1 plant and begin generating revenue.”
Sproule has previously evaluated the methane and helium reserves and resources of the subject
licences for Renergen in 2018 and 2019 (Reserve and Resource Evaluation Report dated 1
March 2019 https://www.renergen.co.za/mha-final-report/).
Helium Reserves and Contingent Resources were reported as components of the non-
hydrocarbon gases of the project, however, no Prospective Helium Resources were assessed.
A presentation by the Company will be released after this announcement and will be available on

The independent resource and reserve estimates contained in the Sproule report have been
prepared in accordance with the Society of Petroleum Engineers (SPE) Petroleum Resources
Management (PRMS) guidance and provide a Technical Value, defined as an assessment of a
mineral asset’s future assessment at the valuation date, under a set of assumptions deemed
most appropriate by a practitioner, excluding any premium or discount to account for market
considerations. The Sproule evaluation is based upon data supplied by the Company,
supplemented where necessary by Sproule’s corporate awareness of current South Africa
industry costs and best practices.
Oil and gas reserves and resource estimates are expressions of judgement 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.
In respect to the Reserves estimates:
o LR5.26.1 Renergen has a high degree of confidence in the commerciality of the project.
o LR 5.26.4 The project will not flare or use as fuel any material quantities of produced gas.
o LR5.26.5 The reference point at which reserves have been estimated is at the outlet to
plant of the on-site gas gathering system.
o LR 5.31.2 Renergen, through its wholly owned subsidiary Tetra4 owns 100% of the
Virginia Production Right area.
o LR 5.31.4 The reserves quoted are deemed commercial based on existing production and
economic assumptions for an expanded processing plant currently in the final stages of
production and offtake agreements are in place.
o LR 5.31.6 Status of the project: The Virginia project currently produces limited quantities
of methane which are sold as CNG to local users. A new plant to produce methane as
LNG, and liquid helium is in the final stages of construction, with commissioning
anticipated early in Q1 2022. The company has in place offtake agreements for both the
LNG and helium production effective on first production.
