Hello @SplitFusion

I may have found the answer to your calculator issues but am happy to be corrected. In the PFS - ore feed for the year is 1.5 MT or approximately 4109 tonnes/day. Sayona, I suspect, has discovered that they can increase the feed rate if you take their comment of 150 kt ROM equating to 30 days at face value - I doubt they would underestimate how many days ROM they had for the purpose of a presentation. 5000 tonnes/day. That equates to 1.825 MT per year rather than 1.5 MT. Now increaseing the PFS calculation of 168 kt sc6 by the appropriate ratio (1.825/1.5) gives 204 kt. If there was improvement in retained lithium to 74% that would increase the output to 226 kt (nameplate).This assumes that they are feeding ore at a similar concentration to the PFS around 1%.

Now it may be that Piedmont made 2 concessions for the sake of the JV and SYA

1. Delaying the offtake start date to July1
2. Accepting lower sc6 grade - maybe 5.5 - 6 if that increases ore throughput (speculative) - as mentioned previously they have been loath to disclose the grade
