Name of the Project
Mina do Barosso lithium project.
Location
The project is located near Boticas, in northern Portugal.
Client
Savannah Resources.
Project Description
A scoping study has confirmed that Mina do Barosso 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 has indicated and inferred mineral resources of 14-million tonnes at 1.1% lithium oxide (Li2O) containing 149 200 t of Li2O using a 0.5% Li2O cutoff.
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 over the life-of-mine (LoM) mill head grade of 1.02% Li2O (diluted) and an average overall strip ratio of 5.2:1 (waste:ore ratio). The project will have an LoM exceeding 11 years.
The flowsheet envisaged 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% Li2O.
