Quick question.

If Samples have already been tested by a Korean Cathode Manufacturer with 99.94% results why would AGY send a further 5 tonne for testing?

Is there a testing regime of sample sizes before you can proceed to the next step?

Looking at the timelines AGY scheduled the 5 tonne shipment before the samples were tested so they must have either been confident that the results would be there or the 5 tonne testing is the successor to the sample testing and precursor to what?

I'm just trying to understand the detail.
