kyrgyz gold sector windfall profits tax

Does anyone know if the prospect of 'windfall profits tax' on Andash has been raised by Kentor or in broker valuations previously? I came across the following in the "MEDIUM TERM DEVELOPMENT PROGRAM OF THE KYRGYZ REPUBLIC FOR 2012-14". Not all that surprising, but still hadn't seen it before.
Of course, Andash has to actually get the go ahead before profits became an issue..

excerpt from avove document:
44. To evening up the tax burden and ensuring completeness of tax collections the following measures will be undertaken:
...
For purposes of reimbursing budget losses, the sales tax rate
will be raised for the communications sector as it is one of the economy’s most highly profitable industries, and a windfall profits tax on gold mining enterprises will also be introduced.

cheers
