I think the $300k cost base wouldn't be too far off. If you take the $30.74m from the Annual Report for "available for sale securities" as at 31/12/12, deduct the Superior Resources Holding (assuming this is classed as AFS) at $45k, you are left with $30.695m. If you apply a notional 30% tax rate to the value of Syrah, you get $9.21m. Deduct the actual Deferred Tax Liability from that notional tax amount and you get a cost of Syrah at $152k or so. Now that assumes all the deferred tax liability is related to the Syrah share holding. If not, then the cost base could be higher accordingly. I am no tax expert, so I could be completely off track!
