Called company, and yes, they cannot disclose monetary values to contracts, hands tied behind their backs.

As some of the contracts are open ended, with continuous revenue streams, (i.e if the product is well received, and more orders come their way).

Many companies operate like this, (another stock O own GTG is the same - via confidentiality agreements / disclosure ).

I am a major holder of ZYL and quite happy to hold, company is doing well. However in stating this they need some hard hitting contracts, one after another in fairly quick succession to force the share price up, until then it is a trading stock. In that it spikes after every announcement, and falling back to near its previous level, if long lead times between announcements.
