San Jose lithium/tin project, Spain
Name of the Project
San Jose lithium/tin project.
Location
The project is located in the Extremadura region of Spain.
Client
The project is a joint venture (JV) between Plymouth Minerals and Valoriza Mineria.
The JV agreement enables Plymouth to earn up to 75% interest in San Jose.
During mine development, Valoriza Mineria will be a pro-rata 25% contributing partner to mine development and capital costs.
Plymouth has earned a 50% interest and expects to increase its ownership to 75% of the project through the completion of the feasibility study.
Project Description
A scoping study has demonstrated the potential for a robust lithium development at the San Jose project.
The project has estimated indicated resources of 23.9-million tonnes and inferred resources of 68.3-million tonnes.
The study recommends mining lithium mica and treating this material using a sulphate roast and water leach process to produce battery-grade lithium carbonate on site.
Conventional drill-and-blast and truck-and-shovel openpit mining methods will be employed. All material will be drilled, blasted and loaded by an excavator in backhoe configuration onto articulated dump trucks.
The trucks will haul high-grade ore using an appropriately constructed haul road to the on-site process facility.
Lower-grade ore will be hauled to an ore stockpile and stored for processing once all the higher-grade ore has been depleted.
Waste rock will be directly hauled by the same trucks to an appropriately constructed waste dump.
The operation has a potential life-of-mine of 24.1 years.
The process plant will treat about 1.25-million tonnes of ore a year to produce an estimated 15 000 t/y of battery-grade lithium carbonate.
Potential Job Creation
Not stated.
Net Present Value/Internal Rate of Return
The project has a base case net present value, at an 8% discount rate, of $401-million and an internal rate of return of 28%, with a payback from the start of production of 2.7 years.
Value
Preproduction capital is estimated at $273-million, The mineral and hydrometallurgy processing components will make up the major cost component of producing lithium carbonate on site.
Duration

Latest Developments
Plymouth Minerals is aiming to attract a strategic industry partner for the development of its flagship lithium project in Spain and is in discussions with European gigafactory developers.
Plymouth has approached international offtake partners, including China and South East Asia.
The completion of a robust scoping study for San Jose in October has enabled the firm to intensify offtake discussions.
Plymouth is now preparing to progress to a feasibility study and has said that it has a shortlist of engineering groups for the feasibility study for its San Jose lithium/tin project.
Announcements are expected in the coming weeks.
