“That mentioned, with out cautious consideration round implementation, a proposal of this scale may jeopardise future investments.”
A movement to reform Chile’s royalty regime for copper and lithium mining has been on the desk since September 2018.
Initially, Invoice 12093-08 proposed a production-based 3% royalty on the full worth (advert valorem) of manufacturing for firms producing in extra of 12 ktpa copper.
A controversial modification handed by the Chamber of Deputies, Congress’ decrease home, in Could 2021, included a sliding scale part to the royalty, WoodMac factors out.
This may set off larger funds when the LME copper worth trades above $2.00/lb ($4,400/tonne) on an annual common foundation, as much as a marginal ceiling of 75% of contained worth at costs above $4.00 ($8,800/t).
The modification has but to be debated by the Senate or signed into regulation.
“Dialogue of the amendments has tended to give attention to a situation of 75% marginal royalty funds coming into play,” Tankard mentioned.
To supply distinction to that headline quantity, our evaluation means that on the $4.00/lb copper worth degree the place a marginal 75% charge is proposed, the efficient royalty charge can be an extra cost equating to 22% of gross income for a mine producing focus.”
Concessionary reduction has been proposed for upgraded manufacturing with the thresholds for 4 copper product classes —focus, blister, anode and cathode.
Wooden Mackenzie thought of the web refining price of Chile’s three electro-refineries, Chuquicamata, Potrerillos and Ventanas, which common 10 USc/lb Cu, as the premise for the extent of cathode royalty reduction.
“As a part of Chile’s nationwide mining firm, Codelco, these three refiners’ concessions can be tutorial, since Codelco’s revenues report on to the state,” Tankard mentioned. “Nevertheless, we have now additionally used that price because the assumed degree of reduction that may apply to Chile’s leach-SxEw mines.”
“Evaluating materials flows from every mine, we assigned the set of measures to Chile’s price base, on the copper worth forecasts utilized in 2025 and 2030 in WoodMac’s Copper Mine Value Abstract.
“This corresponds to forecasts of 275 and 330 USc/lb respectively, each values sitting a way beneath the 400 USc/lb set off worth for the proposed high charge marginal royalty cost of 75% for focus producers,” Tankard mentioned.
Typically, the impression to C3 Whole Value (C1 money price plus depreciation, royalties, company overhead, extraordinary prices and curiosity prices) for Chilean operations can be to push a given operation up the price curve by 10 to twenty centiles.
“Nevertheless, lots of Chile’s mines are already comparatively excessive price and this, for instance, would are likely to push a 3rd quartile producer into the fourth quartile,” Tankard added.
“For the 2025 situation at 275 USc/lb, about 1.4 Mt of costed manufacturing of a Chilean whole of 6.1 Mt can be pushed right into a pre-tax loss-making place on a C3 foundation, up from 0.9 Mt with out the imposition of the royalty.”
Wooden Mackenzie’s evaluation careworn that it’s not but clear how the proposed sliding-scale royalties can be applied throughout the present fiscal framework.

Below the Particular Mining Tax, a quasi royalty applied in 2010, operations producing greater than 50 ktpa copper are topic to a progressive tax on income at charges between 5% and 14%.
“A key ingredient for potential traders can be affirmation {that a} proposed royalty would change the Particular Mining Tax in an orderly manner, somewhat than being levied along with present tax constructions,” Tankard mentioned.
“In addition to the implications for larger prices arising from the proposed royalty, the uncertainty created by the tempo and scale of amendments drafted have the potential to undermine confidence in future, not-yet-committed, venture investments.”
Chile has unparalleled copper useful resource endowment, though as higher-grade ore is progressively depleted, more and more these enormous sources are low-grade.
“Though the royalty as proposed wouldn’t drastically change the manufacturing panorama within the near-term, there’s clear threat it may compromise continued urge for food to make the large-scale, long-term investments Chile has benefited from over the previous 30 years, in favour of initiatives in different jurisdictions that supply sooner or extra assured returns,” Tankard mentioned.
