Name of the Project
Mina do Barroso lithium project.

Location
The project is located near Boticas, in northern Portugal.

Project Owner/s
Savannah Resources.

Project Description
A scoping study has confirmed that Mina do Barroso has the potential to be a major European producer of spodumene lithium, with robust project economics and the potential to deliver substantial shareholder value.

The study is considered a base case for the project and is based on a mine and concentrator-only development for the production of spodumene concentrate.

The project will use a contract miner and fleet.

Conceptual openpit mine planning has been developed, targeting a plant feed rate of 1.3-million tonnes a year, with an estimated average life-of-mine (LoM) mill head grade of 1.02% (diluted) lithium oxide and an average overall strip ratio of 5.2:1 (waste:ore ratio). The project will have an LoM exceeding 11 years.

The flowsheet comprises a combined 1.3-million-tonne-a-year dense-media separation and flotation circuit, with an overall plant availability of 85% for the recovery of spodumene. The study estimates average production of 175 000 t/y of spodumene concentrate at 6% lithium oxide.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at an 8% discount rate, of $356-million and an internal rate of return of 63.2%, with a payback of 1.7 years.

Capital Expenditure
Initial capital expenditure is estimated at between $109-million and $124.6-million

Planned Start/End Date
Production is expected to start in the first quarter of 2020.

Latest Developments
Savannah Resources has managed to continue with a few of its key activities, in spite of Covid-19-related disruptions to other operations.

The company has continued with the finalisation of the environmental-impact assessment and mine plan for the Mina do Barroso lithium project for submission to the country’s national regulator.

Savannah is also progressing financing talks, offtake agreements? and contract services for this project.
