Calyx's Operating Subsidiary Reports Successful Commercial Production of Resonance Brand Feedstock Crop across Western Canada

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 27, 2012) - Calyx Bio-Ventures Inc. (TSX VENTURE:CYX) ("Calyx" or the "Company") announces that the Company's operating subsidiary, Agrisoma Biosciences Inc. ("Agrisoma"), is pleased to report a successful harvest from Agrisoma's first commercial production season.

In the spring of 2012, over 40 separate growing sites comprising 6,500 acres across the southern Prairie regions of western Canada were contracted for the closed-loop production of Agrisoma's Resonance™ brand brassica carinata ("carinata"), a non-food oilseed crop. Carinata oil is an ideal feedstock for the production of value-added products such as bio-jet fuel, renewable diesel, and biodiesel and is ideally suited to the semi-arid growing conditions of the Southern Prairies of Canada and the Northern Plains of the United States.

2012 was the inaugural year of commercial production of Resonance™ carinata. 39 growing sites were contracted for commercial feedstock production and 5 growing sites were planted for pedigreed seed production in anticipation of expanded contracting acreage in 2013. In July and August of 2012, Agrisoma hosted its first annual Crop Walk Series to provide growers and industry representatives the opportunity to learn more about Resonance™ carinata's performance in the field.

Carinata is a sustainable feedstock used for the production of biofuel and is the result of more than a decade of development efforts and advanced crop improvement efforts. Agrisoma's key markets for the Resonance™ carinata include Western Canada, the Northern Plain States and the Southeast United States.

"We are very excited about Resonance™ carinata's performance in its first commercial year," stated Hugh Notman, President and CEO of Calyx Bio-Ventures. "The crop has shown itself to be highly resilient to a variety of growing conditions and successfully withstood extreme weather seen at some of the fields."

"The strong performance of Resonance™ carinata in our first year of commercial production confirms the potential for carinata to provide new opportunities for growers in the production of a non-food feedstock for the rapidly scaling renewable fuels industry" said Steven Fabijanski, President and CEO of Agrisoma.
