Synthesis Energy Systems Announces Financing to Restart

ZZ Joint Venture Plant in China

HOUSTON, September 11, 2013 -- Synthesis Energy Systems, Inc. (NASDAQ: SYMX) ("SES") announced today that its ZZ Joint Venture has obtained the bank financing required to restart the plant for the previously announced cooperation agreement with Xuecheng Energy. The ZZ Joint Venture will expand its operating scope into producing and selling methanol. The annual methanol production capacity is expected to be approximately 90,000 metric tons per year, which SES believes can generate approximately $30 million in annual revenues from the ZZ Joint Venture starting in late 2013 assuming recent average methanol prices in China.

“The ZZ Joint Venture has completed this important step to restart the plant with this new bank loan of approximately $3.2 million,” said Robert Rigdon, president and CEO, SES. “We are moving forward aggressively with the necessary retrofit and upgrades to both the ZZ plant and Xuecheng Energy’s methanol unit so that we can start our planned production and sale of methanol later this year.”

About Synthesis Energy Systems, Inc.

SES provides technology, equipment and engineering services for the conversion of low rank, low cost coal and biomass feedstocks into energy and chemical products. Its strategy is to create value through providing technology and equipment in regions where low rank coals and biomass feedstocks can be profitably converted into high value products through its proprietary U-GAS^® fluidized bed gasification technology, which SES licenses from the Gas Technology Institute. U-GAS^® gasifies coal cost effectively, without many of the harmful emissions normally associated with coal combustion plants. The primary advantages of U-GAS^® relative to other gasification technologies are (a) greater fuel flexibility provided by the ability of SES to use all ranks of coal (including low rank, high ash and high moisture coals, which are significantly cheaper than higher grade coals), many coal waste products and biomass feed stocks; and (b) the ability of SES to operate efficiently on a smaller scale, which enables the construction of plants more quickly, at a lower capital cost, and, in many cases, in closer proximity to coal sources. SES currently has offices in Houston, Texas, and Shanghai, China. For more information on SES, please visit www.synthesisenergy.com or call (713) 579-0600.
