The Yarrawonga is still at anchor off Koolan Island. It's 43152 Gross Tonnage isn't actually a weight. It's more of a volume, or a theoretical volume. The Yarrawonga's Dead Weight [DWT] is 82,624 tonnes. This means that starting with a completely empty ship, you can put in 82,624 Tonnes of 'stuff' to push the ship down in the water to its load limit. This includes fuel, provisions, potable water, stores, the weight of the crew and ballast water, if any.
So I'm going to be very conservative and allow 2624 tonnes for all those other items. Which means there should be 80,000 tonnes of ore coming into the holds of the Yarrawonga at Koolan. We don't know the exact ore grade and several other variables, like contracted prices, so I'm going to just use the Average Realised Price of ore exported from Koolan in the six months to December 31, 2020, as reported in the half yearly. This is $US121. So multiplying 80,000 by 121, should mean $US9,680,000 in the till for this cargo. Which is about $A12,500,000. I would expect that it might be a million or three more, as IO rates have gone up this year.
The Yarrawonga is an (old) Panamax class ship. Which means it was built to be a snug fit in the old locks of the Panama Canal. In 2016, new, much larger locks came in to use to take larger ships, so called New Panamax ships. Still, there are a huge number of (old} Panamax ships this size and Dead Weight capacity in service. I expect what will mostly be coming to Koolan Island to load will be ships of about 80,000 DWT, the same as this one. Every time one leaves fully loaded, it'll be about $A12,500,000 in exchange for some red magnetic dirt. Ka ching!
If one ship comes in every nine days on average, thats 40 ships per year, which is 500 Million revenue for MGX.
