Taking a cue from Australia, the PH government seeks to be more creative taxing large-scale mining. Why not? But the usual impact-on-competitiveness objection is naturally being raised:
Rocky G. Dimaculangan, vice-president for communications of the  Chamber of Mines, said the organization had yet to study the impact of a  carbon tax and a mineral resource rent tax.
“Nevertheless, the government is already getting its fair share  of revenues from large-scale mining companies through the array of taxes  currently imposed on us. They should focus instead on collecting taxes  from the small-scale and illegal operations,” Mr. Dimaculangan said.
