History of the Theunissen project
3
By 2008 he has successfully developed
the first UCG proposal at Sasol; proving
the value of this exciting technology.
Mr Brand became the UCG Business
Manager for Sasol, Director of the UCG
Association in London + the Technical
Director of Wildhorse Energy
Mr Monkoe left Sasol Mining in 2006 to
become COO at Ingwe Collieries and later
non-executive Director at Optimum Coal.
He was part of the Optimum buy-out
where he retained a substantial
shareholding and became financially
independent at the listing of Optimum.
In 2001 Johan Brand (Mining Engineer) and
Eliphus Monkoe (Operations Manager) met
at Sasol Mining as part of the Brandspruit
Mining team.
Eliphus told Johan about his experience in
the Former Soviet Union where UCG has
been implemented since the 1940’s.
Together they initiated the implementation of
UCG at Sasol.

African Carbon Energy (“Africary”)
• African Carbon Energy was established as a South African coal mining company in 2007 as a 50:50 Partnership between Johan and Eliphus.
• The company was founded on our expertise in mining, exploration, gasification and specifically Underground Coal Gasification (UCG) and our business philosophy then is to support equity investments with operational involvement
• From 2011 to 2012 Africary finalized the deal for a massive coal resource from BHP Billiton SA that is ideally suited for UCG in the Free State.
• We also bought 2 farms ideally placed for our first project.
• Our business philosophy grew to invest and develop our own UCG to Power project on the Theunissen resource for implementation in the DoE process.

AFRICARY’s vision
“To build own and operate a
Modern Commercial UCG plant”and then grow to large scale Poly-generation
Low cost and abundant resource “COAL”
Growing market demand “ELECTRICITY”
rising price and 30 year off-take agreement
Clean, Green and efficient technologies “UCG”
Use learning and experience from other projects to
fast-track and focus

Coal gasification is an old concept
UCG has a long history… • Coal gasification was used more than 150 years ago to produce “town-gas”
for lighting streets in the UK and the US • Sasol (South Africa) has been gasifying coal for over 50 years and currently
produces about 40% of the nation's current liquid fuel requirements (160,000 bbl/day)
• Commercial UCG has been successfully operated in 15 mines for more than 50 years in Russia – supplying UCG syngas for power generation

Over a 6 month period with the injection flow rate kept constant 1500 nm3/hr, the
graphs indicate changes in volume of syngas produced and the energy content of the
syngas.
There is clear correlation between these two parameters, when there is more gas
being generated, the gas is of higher energy content.

Why UCG in SA?
With Eskom’s 7 years production experience at Majuba – UCG is a proven SA
technology
With increase in tariffs electricity generation by gas engines is cost competitive!
The graph below shows the increase in the average annual selling price of Eskom
electricity from 17.91c/kWh in 2006 to 79,73c/kWh in 2015 and is set to continue this

Advantages of Africary's commercial UCG
technology – positive environmental impact
UCG power generation produces 25% less CO2 per MWe and in large scale
Combined Cycle mode can reach energy efficiencies of up to 58%
compared to current 35%.
UCG has no dust particulate emissions or ash handling AND little or no
leaching of trace elements from ash when operated correctly / optimally
UCG mining and power generation uses 90% less water
Less sulphur and heavy metals are released or emitted by the UCG
process
Gas Engines offer higher fuel efficiency (up to 40%), than any boiler
operated in SA today (±35%)

Advantages of Africary's commercial UCG
technology – positive social impact
UCG can monetize economically unmineable coal that would be otherwise lostto the economy (<26% of coal reserves recoverable with conventionalmining…Source: U.S. Energy Information Administration, “International EnergyStatistics: Coal,” 2011)
New high value jobs created in the drilling, gas processing and gas engine /CCGT maintenance industries
UCG projects can be located in economically depressed areas away fromcurrent mined areas
There are no chemicals used in the UCG process as only air and water are usedfor gasification
No fracking required and there are no drilling chemicals injected when drillingthe boreholes
Clean Coal Technologies provide a much needed injection of R&D capital with anew industry being developed and creating high value jobs
