The modelled tax rates will directly impact the NPV of the project/PFS. And if a Royalty structure is implemented it will be even more detrimental.
An increase from 18% to 30% tax is a reduction of 12% in the NPV of the project - it will directly impact the investment decision and reduce the potential takeover price.
Pro-green / clean energy spin is fluff compared to the bottom line of the balance sheet.

Dont get me wrong I’m all for fair and equitable distribution - but if the government or the public arent willing to invest in getting the dirt out of the ground I am absolutely against scalping the people who do take that risk. Look at what happened when Kevin Rudd and Gillard introduced the Mining Resource Rent Tax and the Mining Super Tax scheme - the large existing players played around with their books to avoid as much of it as possible, while the smaller resource development projects were shut down because the tax hike had to be modelled into the future mine and of course it was detrimental and a lot of investment projects when on hold. And Boric is even more left/socialist than Gillard and Rudd were.
