The company advised in the Jan-March 24 Quarterly report that Blair Athol's coal sales were revised to 1.7mt. In that quarterly report, they advised that 75kt didn't make it onto the shipping and fell into the June quarter (image below). So that meant they needed to have 541kt of coal sales in the June quarter. They did 408kt, which included the 75kt that was at the docks from the previous quarter.
426kt - Jul-Sep 23
418kt - Oct-Dec 23
315kt - Jan-Mar 24
408 - Apr-Jun 24 (541kt was needed to reach 1.7mt worth of sales from BA)

If you go back through the quarterly reports over the years, you'll constantly find that the coal was on the train but didn't make the ship, the dragline needed repairs, and the weather was bad. At the start of the year, they said Blair Athol had a coal sales target of approximately 2.0mt (this should factor in any risks). This was then reduced to 1.7mt coming into the final quarter, and then they produced 1.56mt. That caps off a terrible FY24.

I hope this fiscal year, FY25, has significant improvements.
