Croesus - blast from the past

Hi All,

Could any long term SIR holders shine any light on an issue I have discovered? In my trading transactions I found that I had bought Croesus Mining (CRS) shares circa 2006. I have no record of them being sold. From what I can gather they were suspended for a long period, placed into administration, recapitalised, then renamed Sirius Resources. Because they were not delisted, should I still have a requisite amount of SIR shares? Computershare can not shed any light on the matter as on their system it says I do not have any positions with SIR.
Did anyone come by their SIR shares through a holding in Croesus Mining, and if so, what sort of dilution should I expect?

Thanks in advance,
Andy
