Unsure. Would need to be held in some way to protect it from the elements.
Here's photo of the first load on the MV Ocean Flower.
The second shipment was just over 19,000 tonne and that was originally around 17,000 but increased due to the MV Karine being slightly delayed in arriving at the Bunbury Port. Link
It would be nice to hear of another export sooner rather than later since we have stock ready to go. That export will seal the GMM / GXY alliance and bring confidence to the project. Now that will be a photo worth posting.
