My understanding is companies (producers) with offshore assets such as SDL (not yet producer), PNA (copper/gold at Laos) and RIV (coal at Mozambique, Africa) should be less exposed with Henry Tax system than their peers (OZL, FMG, etc..) in Australia.
The new tax system if applied, will put on-shore miners at disadvantage as they have to pay 40% Resource Rent Tax, so their NPVs (profits, P/E) will drop significantly in long run.
