Calyx Provides Update on 2013 Resonance(R) Carinata Contracting Program

VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 30, 2013) - Calyx Bio-Ventures Inc. (TSX VENTURE:CYX) ("Calyx" or the "Company") is pleased to provide an update on the Resonance® carinata growing program currently being conducted by its majority-owned subsidiary, Agrisoma Biosciences Inc. ("Agrisoma").

The 2013 growing program was introduced on March 26, 2013, at a day-long event held in Swift Current, Saskatchewan, in connection with the Government of Saskatchewan's Ministry of Agriculture, the Saskatchewan Mustard Development Commission, and Prairie Gold. The presentation covered a range of topics of interest to potential growers, including agronomics, Resonance® carinata breeding and varieties, crop inputs (fertilizer, weed & insect control), crop insurance, and grower experiences from last year.

The 2013 contracting program is in progress. Spring has been colder and longer than normal this year. Farmers in Alberta, Saskatchewan and Manitoba usually begin planting in late April in southern areas, but 2013 planting has been delayed for many growers. The delayed planting season and resulting shortened growing season is not expected to impact the ability of growers to successfully cultivate Resonance® carinata in the current year. A further update will be provided when the growing season progresses.
