Ann: Clarification, page-21

"The Company would like to reiterate that the initial production sample testing is preliminary in nature and cannot be relied upon until a full production reconciliation is completed in the coming months. As the commercial expansion of the project continues and more product sampling is reconciled, the Company will update the market accordingly."

So either one of two things can be inferred from the release.

1. SC6 has not yet been produced
2. The lab cannot produce accurate results.

The announcement states that the lab is fully commissioned so I think its fair to discount that.
If they could prove SC6 was produced, common sense tells us they would be only too happy to clarify that thats the case but they still cant provide those details.
