Savannah Resources demonstrates the viability of feldspar and quartz as co-products at the Mino do Barroso lithium project

The sale of the by-products could end up significantly reducing costs

Savannah Resources PLC -
Mino do Barroso remains one of Europe's largest lithium projects

Savannah Resources PLC (LON:SAV) has completed a glass and ceramics test work programme on the feldspar and quartz that are found at its Mina do Barroso lithium project in Portugal.

The work demonstrates that feldspar and quartz from Mina do Barroso's spodumene concentrate tails are suitable for use in a range of glass and ceramic applications.

It has also confirmed that the bulk tail from the spodumene concentrator is also a saleable product requiring no further processing.

Meanwhile, marketing studies have concluded that prices for Mina do Barroso co-products could be significantly higher than reported in the 2018 scoping study, with feldspar at between US$65 and US$100 per tonne, and quartz at US$60 to US$100 per tonne.

Glass and ceramics are two of the biggest global markets for feldspar and quartz

Accordingly, discussions are underway with potential offtake and joint venture partners to advance the co-product opportunity.

Savannah is currently targeting an average annual production rate of 175,000 tonnes of battery grade spodumene lithium concentrate from Mino do Barroso, in addition to targeting the production of feldspar and quartz co-products for the regional glass and ceramics industries.

"Glass and ceramics are huge global industries, with Europe representing 25% of global production of ceramics,” said Savannah chief executive David Archer. 

“Feldspar and quartz products have been produced in this region of Portugal for decades and are well regarded by glass and ceramic manufacturers in the domestic market and in Spain. The completed test work has validated Mina do Barroso's feldspar and quartz for these applications. Producing saleable products from the waste stream of the spodumene concentrator will help to reduce the operating costs and the footprint associated with handling and storing waste material on the project site.”
