@Hiddenvalue, it would be a total miracle if either of those options you've mentioned actually materialized...probably as likely as WMC producing at a rate of 110k -120k oz p.a by end of Dec'22.
The previous mine owners (Apex Minerals) spent a $Motza on Wiluna and then BLK bought the mine for not very much in 2014 (refer below). I don't think the sale value will be as low as the 2014 numbers, but it does seem likely the dollars involved will be opportunistic (whatever they turn out to be).
