Corporate Update

Updated CPR confirms Chariot's estimate of gross mean unrisked prospective resource volumes

Chariot Oil & Gas Limited (AIM: CHAR), is pleased to announce the results from its latest independent Competent Person's Report ("CPR") from Netherland Sewell & Associates Inc. ("NSAI") which reports gross P50 unrisked prospective resource volumes of 14.4 billion barrels ("Bbbls") with gross mean unrisked prospective resource potential of 16.1 Bbbls, a slight increase of 3.5% or 535 million barrels, within Chariot's licence areas offshore Namibia.

Highlights:

·; P50 risked resource potential of 2.2 Bbbls (Net to Chariot - 1.5 Bbbls)

·; Based on NSAI's gross, risked discounted cash flows for the entire prospect and lead inventory Chariot determines a net Expected Monetary Value ("EMV") of £11.2 billion (P50) - corresponding to £7.47 (US$12.00) per net risked bbl

·; Probabilities of Success in line with Chariot risking

·; Supports the investment case and the work carried out by Chariot's in house technical team

This CPR updates a previous study which reported gross P50 unrisked resource volumes of 9.0 Bbbls with gross mean unrisked resource volumes of 10.1 Bbbls, as announced on 28 October 2010. The earlier study was undertaken prior to the identification of further resources in the Tapir Complex in the Northern licence and the Nimrod prospect in the South. The updated potential resources resulted primarily from the reprocessing of 3D seismic data and subsequent AVO analysis work.

As part of this update, NSAI undertook a geologic risk assessment on the updated prospect and lead inventory as identified by Chariot and conducted an independent review of the individual prospect and lead risking. Overall, the CPR resource volumes were slightly higher than Chariot's estimates with a gross mean unrisked figure totalling 16.1 Bbbls, with increased figures for both the P10 and P90 estimates. NSAI's risking was broadly in line with Chariot's risking across the whole inventory, with minor adjustments to some prospects.

On receiving the report, the Company has calculated a total risked EMV of £11.2 billion, equivalent to £7.47 (US$12.00) per net risked bbl, up from £4.6 billion, equivalent to £5.98 (US$9.27) per net risked bbl as previously stated.

Paul Welch, CEO of Chariot, commented:

"These volumes have resulted from the extensive geological and geophysical work undertaken by the Chariot technical team across all our licence areas. It is very satisfying to continue to have third party endorsement of our prospective resources. Having established the potential of our assets, we now look forward to the next stage of our development and the drilling of our prospect inventory."

Please see table below for a breakdown of the key figures from the CPR.

Totals are the arithmetic sum of multiple probability distributions and may not add up because of rounding.

(1) NSAI have not summed post-tax cash flows because of the expected interdependence of prospects and leads. The oil price used for economic analysis is a Brent crude price of US$85 per barrel escalated at 2.5% per year.

(2) In accordance with the PRMS, we have reported the low, best, and high estimates for each prospect and lead. As requested, we have also included mean estimates for each prospect and lead.

(3) These prospects demonstrate amplitude-offset-with-variation behaviour that may be a direct indicator of the presence of petroleum.

(4) Leads in the Central Licences were assessed with 2D seismic data only; all other prospects and leads were assessed with 3D seismic data.

The resources in the report were estimated using a combination of deterministic and probabilistic methods and are dependent on a petroleum discovery being made. These estimates were prepared in accordance with generally accepted petroleum engineering and evaluation principles and in accordance with the 2007 PRMS definitions and guidelines as approved by the SPE.

QUALIFIED PERSON Martin Richards, Chariot's Development Engineering Manager, is the qualified person for the purpose of this release. Martin has worked in the oil and gas industry for over 30 years and has an in-depth experience of all aspects of subsurface management, reservoir engineering and petroleum economics. He has an MA in Physics from Oxford University, an MSc in Geophysics and Planetary Physics from Newcastle University and an MEng in Petroleum Engineering from Heriot-Watt University. He has read and approved the technical disclosures in this announcement.
