The study is based on a 30-year operation life with US$267.9 million earmarked for pre-production capex.
The PFS combines a long-life, low-cost open pit or quarry operation with a processing plant located on-site and within 2 kilometres of the resource.
Project essential to Europe’s goal of securing critical lithium chemicals
Infinity’s managing director Ryan Parkin said: “The PFS has confirmed San José as a long life, low cost Project that is essential to meet the European Commission’s goal to secure critical lithium chemicals that are imperative for the economic survival of their automotive industry.
“The value of the Project is significant with a pre-tax NPV10 of US$860m and an attractive IRR of 42% over an extended project life, which, when coupled with the potential support of major European institutions such as the European Investment Bank, provides confidence for the development of the flagship lithium chemicals Project within Europe.”
Notably, the project life has been extended by 25% from 24 to 30 years of production.
The 30-year project life comprises 19 years of mining with the processing plant to continue operation for 11 years using stockpiles after mining finishes.
Tin and boron could add more value
Potential tin and boron credits are available and are being assessed in the ongoing optimisation studies.
Additional work is required to define a value of the potential by-product credits, or if it would be economic to extract value from these credits.
Below is a graphic representation of the project’s forecast operation.
Parkin added: “The Project presents the potential for exceptional multi-decade employment positions and tax revenues that are largely retained within the region of Extremadura, whilst also providing a world class beacon for complementary activities in lithium-ion battery production and technologies in the region and throughout Spain.
“San José retains unique sustainability characteristics that further complement Europe’s aggressive carbon emissions compliance requirements through the implementation of an environmentally advantageous process flowsheet and superior carbon emissions profile for European end markets.”
