Key Highlights
• 23 % uplift in unrisked licence-wide prospective resources to c. 4.31 billion barrels (mean).
• 618 million barrels (MMbbl) unrisked net mean now further attributable to GEO’s 78% working
interest (103 MMbbl risk-adjusted) in PEL94.
• Prime Walvis Basin “sweet-spot” location in 350–1 550 m water depths; regional successes in
the Namibia’s Orange Basin (Venus, Graff, Mopane) underline the country’s deep-water
potential.
GEO Exploration Limited (AIM: GEO) is pleased to announce the results of an independent
geoscience evaluation of Licence PEL 94 (Block 2011A), offshore Namibia. The study has greatly
enhanced our understanding of the potential in the eastern portion of PEL94 and it has identified two
new sandstone leads - Emerald (in the Albian) and Beryl (in the Cenomanian). The work confirms
substantial upside and a materially de-risked resource base.
The evaluation concludes that Emerald and Beryl together contain 792 MMbbl of unrisked gross
mean prospective resources, with 726 MMbbl attributable to Emerald and 66 MMbbl to Beryl. At
GEO’s 78% working interest this equates to 618 MMbbl of net mean resources, while the assigned
weighted Geological Risk Factor (or geological chance of success) yields 103 MMbbl of risk-adjusted
net mean resources.
Importantly, these upgraded numbers lift the licence-wide unrisked gross mean prospective
resources on PEL 94 to approximately 4.31 billion barrels, representing a 23 % increase over the
3.52 billion barrels announced on 27 March 2023. On a risked net basis, GEO’s share has grown by
roughly 32 % to 429 MMbbl.
Seismic mapping has delineated robust, dip and fault-bounded structural closures. The seismic
data interpretation has also highlighted direct hydrocarbon indicators in the area—including gas
chimneys and flat spots—providing strong evidence for an active petroleum system, migration of
hydrocarbons throughout the section and therefore increasing the chance that the leads are charged
with oil. The water depth is c.750 m at the location of the leads identified.
The 5798 km² licence area sits within the Walvis Basin “sweet-spot,” an area benefiting from
improved charge maturity modelling, while recent world-class discoveries in the Orange Basin to the
south (Venus, Mopane, Capricornus) highlight the prolific nature of Namibia’s Atlantic margin.
Omar Ahmad, Chief Executive Officer of GEO Exploration Limited, commented:
"Before commenting on these exciting results, I would first like to congratulate Her Excellency Dr
Netumbo Nandi-Ndaitwah on her appointment as President of Namibia and Victoria Sibeya on her
appointment as Acting Managing Director of the National Petroleum Corporation of Namibia
(NAMCOR). I would like to thank Petroleum Commissioner Maggy Shino, the Namibia Ministry of
Mines and Energy and our partners for their continued support to Geo.
Today's resource upgrade underscores the tremendous potential we see in PEL 94 and the strong
conviction we have in our Namibian licence. Our technical team has done a terrific job delivering
new, material leads on the eastern side of the block. With excitement building across Namibia—and
particularly in the Walvis Basin—we are actively progressing farm-out discussions to secure the best
outcome for our shareholders"
Volumetrics of Prospects and Leads for PEL 94
The Prospective Resources are detailed in Table A below and have been classified in accordance with
the Society of Petroleum Engineers Petroleum Resources Management System (SPE-PRMS), and have
been estimated using a probabilistic method. They are based on 3D and 2D seismic data and
geological information, including analogues, to which GEO has access. The prospects are considered
viable drilling targets. The leads require more data and/or evaluation before they can be considered
viable drilling targets.
